StingRay FAQ’s

StingRay Administration (17)

Why can’t external users see their files after reconnecting?

When you upload files to the StingRay using an incoming address book entry, they will show for the time you are connected and “vanish” the next time you connect. This is perfectly normal behaviour and happens due to the way the StingRay works and how it maintains high system security.

When you connect to the StingRay, it creates a “virtual session” specific to your session. There are no physical directories where files are stored. As soon as you disconnect, the files are moved into the database and the virtual session is terminated.

There is a way of notifying users of the files that have been uploaded via email. This way they can always keep a log of what was uploaded to the StingRay and when. View  When I send files in, I want to know what was uploaded. How do I do this? for the instructions.

Note: This does not apply to exchange connections/ftp sessions, in which files will always be displayed. This is due to the StingRay’s FTP server emulation capabilities.

My disk is still full after deleting files, why is this?

The StingRay does not delete files in the incoming and outgoing queues immediately, but rather marks them for deletion. The StingRay purges the database every 48-72 hours and as a result means the files you’ve marked for deletion will remain there until the database runs it’s next scheduled purge.

If it is necessary to immediately remove files from the StingRay’s incoming and outgoing queues, for example if you’ve completely run out of disk space, there is a method of forcing a database purge. You can do this following the steps below:

1) Log onto the web interface as an administrator.

2) Navigate to System Configuration.

3) Scroll to the bottom of the page and click Edit.

4) Set the date manually, it is suggested to set the date 1 month in the future.

5) Save.

6) Navigate to Hardware Configuration

7) Click Reboot on the bottom right.

After a reboot, the StingRay will immediately purge the database as it starts up. Once it’s fully rebooted follow the steps above once again to set the date back to the present. One final reboot is necessary to confirm the date.
You can confirm the files have been removed by navigating to Hardware Configuration and checking your free space.

Note: This FAQ pertains to the incoming and outgoing queues only. If your disk is full due to exchange data this method will not clear that data. You will be required to log into the exchange accounts manually and delete the necessary amount of data to free up disk space.

How to configure your StingRay to send jobs as a Hyperlink (web)

If you would like to be able to send jobs to an email address as a link (Hyperlink) to which a user can click and download the file you’ve uploaded, follow the instructions below:

Log into the StingRay’s internal web interface as an administrator.

Navigate to Address Book.

Once in the Address Book click NEW in the top right hand corner.

Here is an Address Book entry I made earlier:

Under General Information, the most important fields are Company name and Recipient name. The other fields are optional when creating an account for FTP access. Ofcourse, filling them will make it easier for you to add new roles in the future should you wish to do so.

Outgoing settings must be filled in, this is the category which tells the StingRay to send a HTTP link to an address book entry’s email address. The important fields are the email address and selecting “HTTP Link”. You will also notice that Data Access enables itself and inserts a random user and password. This is normal.

The Incoming settings do not need to be filled in.

Receiver Assignment - You may notice FTP is moved to the right. This is normal.

Please now click SAVE!


Now you can head to “Create Sendjob” and use the new addressbook entry you just created in the “Address:” field.

And watch as it shows up in your user’s email inbox:

Clicking the link will download the file in the user’s default browser.

Congratulations, you have now created an address book entry which will allow you to send jobs from the StingRay as a Hyperlink to a user’s email address for them to download at their convenience. 
If you require assistance with this, please get in touch with support.

StingRay Client (8)

What are the differences between StingRay clients, and which one can I use?

There are three widely used versions of our StingRay client;

Version 3.0 for Mac OS 10.5 (Leopard) and above.
Version 1.2.1 for Mac OS 10.4 and below.
Version for Windows XP and above.

In version 3.0, we fully integrated the StingRay Client into Mac OS 10.5 and above. No more Rosetta!

In addition, version 3 uses Quicksend. This feature enables you to send a job directly to any email address without having to create an addressbook entry beforehand. This feature works with StingRay firmware version 2.6.0 and above only.
If you’re using an older version of the StingRay client you can still create hyperlink sendjobs. All you need to do is create an addressbook entry using the StingRay’s web interface before sending a job to your recipient.

In order for you to be able to use the StingRay Client, you must first purchase the appropriate license for the Client version you wish to use. As long as you maintain the most up to date Mac OS and StingRay firmware, you will be able to use any new features we publish.

To see which version of the StingRay client you can use based on the Licenses you have, you can log into the StingRay’s internal web interface as an administrator and navigate to Client Licenses.

As you can see with the example above, there are two types of StingRay Client license:

Leonardo Internet Express

- This is for the Mac OS of 10.4 and below running StingRay Client version 1.2.1
- This is for Windows (all versions) running

StingRay Client

- This is for Mac OS version 10.5 and above running  StingRay Client version 3.0 and above.

Assigning a license to your StingRay Client is as simple as signing into your local user account within the StingRay Client on your computer. Unassigning a license is also very easy, simply log into the StingRay’s internal interface and click the red button next to the license located in Client Licenses. It will then free up the license to be used by anyone else who may require it..

Red - A license has been assigned to a device and is not available.
Green - A license is available and ready to be used.

If you require any further information pertaining to the StingRay Client software or the licenses used with the client, please do not hesitate to get in touch with us.


Access Data Server from the StingRay Client

To access the Data Server from the StingRay Client please do the following:

1) Open the StingRay Client
2) Click File > Data Server *
3) Wait for the list to the right to populate.
4) Double click Addresses
5) Double click the address you have created as an Exchange account
7) Double click Exchange

You are now in the Exchange folder of the Address Book entry via the StingRay Client. You can upload and download files as you wish.


* If Data Server is greyed out you will need to do the following:

1) Log into the web interface as an administrator
2) Navigate to Local Users
3) Click your user account (the account you’re signed into on the StingRay Client**)
4) Click edit

Under Transfer and Database rights, on the right hand side you will see a check box “Allow internal dataserver access” check it and click Save.

5) Restart your StingRay client. Data server will now be available.


** To find out which account you’re signed into on the StingRay Client, do the following:

1) Open the StingRay Client
2) Click the Application menu (one left of “File”) and select Preferences.
3) Click your StingRay (in the white box) and click Edit.

Now you will see what local user account you’re using to connect to the StingRay.

Windows StingRay client requests StingRay info at each launch

If you are prompted by the same screen every time you launch the Windows version of the StingRay client, it is most likely because you are not an Administrator of that Windows PC. The client requires Administrative privileges in order to write the StingRay Client preferences to your computer. Without them, it cannot do this.

In order to sign into the client and retain the preferences for each application launch thereafter, please do the following:

1. Log out of your limited user account in Windows.
2. Log into Windows as an Administrator.
3. Launch the StingRay Client (you may be required to redownload it from www.hermstedtstingray.com).
4. Input the StingRay and user settings you wish to use and continue to log onto the Client.
5. Log out of your Administrator account in Windows.

When you now log in as your limited user account and launch the StingRay Client application, it will no longer ask you to input any credentials.


Note: To change credentials in future, you should simply be able to change them in the preferences now that the preferences file has been saved. If for any reason you are unable to save them, you will be required to follow this guide again, with some slight differences:

1. Log out of your limited user account in Windows.
2. Log into Windows as an Administrator.
3. Launch the StingRay Client (you should already have it on the Admin account now).
4. Click File > Preferences and select the StingRay tab.
5. Select the StingRay to change preferences for and click Edit.
6. Change the credentials as required and Click OK twice.
7. Log out of your Administrator account in Windows.

When you now log in as your limited user account, you will have the new credentials when you launch the StingRay Client.

Following this guideline will ensure your logo will fit perfectly within the external web interface.

How do I change the colours in the External Web Interface?

 We’ve worked to make it as easy as possible to edit and customise the colours within the External Web Interface. If blue isn’t your colour of choice, then follow these steps and you’ll be up and running with your own colours in no time:

1) Log into the StingRay’s Internal Interface as an administrator.
2) Navigate to Network Configuration.
3) Under the heading “External Web Access” click “CSS Download” on the bottom right of the category.
4) If a new tab opens with the CSS displayed as a web page, please Right Click > Save as to download the file.
5) Open the file in your preferred text editor. (- Notepad++ is excellent on Windows.)

Immediately you are greeted with a notice:



These will need to be set in the CSS below dependent on how the user wants to customise.


The Primary colour is the main colour – the slightly darker blue in your External Web Interface.
The Secondary colour is the main blue colour of your buttons and the lighter bottom border on the header.

If you have a Primary and Secondary #colour available, simply find each instance of the #colour and replace it with your own. If you’re looking for colour codes, check out Where do I find colour codes to edit the StingRay CSS file?

Primary Colour: 5 instances
Secondary Colour: 9 instances 

Once you’re finished, save the file and do the following:

1) Log into the StingRay’s Internal Interface as an administrator.
2) Navigate to Network Configuration.
3) Click Edit.
4) To the right of Custom Weblogo or Stylesheet click Choose File.
5) Upload the CSS file you downloaded and click import.

You’ll be shown a message of confirmation when the upload completes and the changes will be effective immediately. You may need to refresh the External Web Interface page a few times or clear your cache if you don’t see the changes immediately.

If you make a mistake, don’t worry – here is the original CSS file, just re-upload it to the StingRay to restore the default colours. Note: This will change ALL colours back to the blue default!!

Download Default CSS

StingRay Features (7)

How do I send a file from the internal web interface?

There are two ways to send a file from StingRay’s internal web interface – It can be done by either selecting an address book entry or by using the built in quicksend option. The two procedures are listed below:

Send to an existing address book entry:

1) Log into the internal web interface.

2) Navigate to Create Sendjob.

3) Select an address from the list*.

4) Enter a subject.

5) Choose a file.

6) Set the priority of the job.

7) Click Send Job.

*It is possible to use the search function to the right of the listed addresses. When browsing an exceptionally long address list the search function can be much faster than browsing address by address. If you are unsure of the name you are looking for or it’s spelling, simply enter a few characters and click search. All relevant address book entries will be listed.

**The file will be sent via the protocol specified in the addresslist, for example User1 might be specified to receive jobs over FTP, while User2 may only be sent and email with the link to download from the StingRay itself.

Send a quicksend job
- This allows a user to send an email with a hyperlink without the use of the address book:

1) Log into the internal web interface.

2) Navigate to Create QuickSend.

3) Enter the email address of the receiving party.

4) Enter a subject.

5) Add a message if required.

6) Choose a file.

7) Click Send Job.

How do I create folders in the Exchange area?

By default, the Exchange area is one directory with no subdirectories. If you would like to add subdirectories, you will need access to an FTP client. Once you’re logged into your Exchange account and, as such, your Exchange area, you can add folders at will.

It is also possible to add folders using the StingRay client, however, adding folders via the web interface is not possible.

What is the difference between Incoming and Data Server access?

When you create an addressbook entry, you have the option to enable Incoming access, Data Server access, or both.

Here is a brief outline of each one:

Incoming Access

▪    Can be accessed via both FTP and the External Web Interface

▪    Files are uploaded and are no longer accessible for the user uploading.

▪    Files uploaded can be accessed by a Local User in Incoming Jobs

▪    The StingRay actively manages these files and will periodically self-clean.

▪    Files uploaded can be immediately forwarded to another location

▪    Notifications are available on upload.

Dataserver Access

▪    Can be accessed via both FTP and the External Web Interface

▪    Files uploaded are always accessible when logging into the External Web Interface.

▪    Files uploaded will not show in Incoming Jobs

▪    The StingRay will not actively manage the dataserver area. Files will remain forever unless removed.

▪    External Users must be given permissions to upload and delete files via the addressbook entry.

We generally only suggest using the Dataserver on rare occasions. Most of the time Incoming Access is sufficient for every day transfers, and being self cleaning means you will not have to actively manage the StingRay.

If Dataserver access is used and not maintained, when the disk becomes full you will encounter problems.

StingRay Firmware (2)

How to install a License file onto StingRay?

To install a license file, follow these steps:

1) Unzip the license file. Usually they are sent in a zipped format. The file should end with .bin once unzipped.

2) Log into the web interface as an administrator.

4) Navigate to Import/Export.

5) Scroll down the page until you come to import.

6) Leave “Creating only records (same records will be ignored, new data will be added)” checked and click on the drop down box. In this drop down you need to click System/license update.

7) Once you’ve selected System/license update you can browse for the file and click Import.

The license will update immediately, and you can check it’s successfully updated by navigating to Site Information.

How do I update the StingRay firmware? Do I need to update?

Keeping up to date with StingRay firmware is strongly recommended. It fixes bugs, adds functionality and increases productivity. To check you’re running the latest version, and to update if necessary do the following:

1) Log onto www.hermstedtstingray.com/services-support/technical-resources and scroll to StingRay Firmware Update Files.

2) Log into the web interface of the StingRay as an administrator and scroll to the bottom of Site Information.

Compare the versions, if your version is the same as the latest release then you’ve nothing to worry about, and there’s no need to update your firmware. However, if you are running a lower version, you should update.

Before you begin the next steps, make sure you’re entitled to update your firmware. On some updates a charge will be incurred. Contact support if you are unsure whether you’re entitled to a free update or not. If you are, follow these steps:

** Before you update your StingRay you should always create a manual backup. To manually back up your StingRay you can follow these steps.**

** Make sure your license is up to date. Log in to the web interface as an administrator and scroll to the bottom of the page. You should see either Valid or Invalid. If your license is invalid, you will need to renew it. Contact support. If you have a license, but need to install it, you can follow these instructions.**

1) Log onto the web interface as an administrator.

2) Navigate to Import/Export

3) Scroll down the page until you find Import.

4) Leave “Creating only records (same records will be ignored, new data will be added)” checked and click on the drop down box. In this drop down you need to click System/license update.

5) Once you’ve selected System/license update you can browse for the file and click Import.

**The StingRay will reboot once you have clicked Import! Make sure no one is using the StingRay while you are updating it!**

The StingRay will update itself, and reboot. Once it returns to it’s fully powered on state (this may take a short time after an update – don’t be concerned) it should be fully updated and ready to be used again, often with extra functionality (this can be seen in the change logs).

You can confirm the StingRay successfully updated by logging into the web interface as an administrator and scrolling to the bottom of the Site Information page. The firmware version should now reflect that of which you installed.

If you require any assistance, please contact support.

StingRay FTP Queries (4)

I can authenticate via FTP, but I can’t send a file, why is this?

When you connect with an FTP client to the StingRay, it will get as far as authentication and then time out.
 This commonly occurs when the StingRay is sitting behind a firewall which does not allow passive connections.

Unfortunately to send a file you will need to disable passive mode on your FTP client. To do this, please refer to the documentation available for your FTP client.

Why are my files being sent with a .bin extension?

 If you are sending files via FTP using StingRay and the receiving site is receiving them with a .bin extension then there are two possible reasons for this. In the address book entry for the site you are sending to there is an option to set Mac Extra.

This field determines how the files are transferred from StingRay to the remote site. This setting can depend upon the remote site, chosen protocol and the type of data. There are 3 options to choose from:

▪    Full: All file information is transferred to the remote site. (Default)

▪    Data-fork only: Only the data-fork is extracted from the file and sent to the remote site.

▪    MacBinary: The file is transferred to the remote site as a MacBinary file.

Setting the ‘Mac Extra’ for the outgoing job will change what questions the StingRay server asks the remote FTP server. Full will make the StingRay ask ‘MACB’ – if it gets a reply saying the remote server supports this then it’s very likely the files will be sent in a MacBinary format.

Try setting the option to ‘Datafork Only’, as this will just send the file in a binary format but will strip the resource fork. This is fine for files not susceptible to corruption for example PDF or TXT files.

Why am I disconnected from my FTP session?

By default, there is an inactivity timeout of 5 minutes on FTP sessions.

If the connection is left open for over 5 minutes, on your next action you will automatically be reconnected to the StingRay.

StingRay Hardware (5)

The Power Button, Shutdown, Reset, Enable SSH

The StingRay power button is programmed to provide three individual tasks depending on how many times you press it.

Pressing it once will Shut Down the StingRay.

Pressing it twice will reset the network configuration to factory defaults. The StingRay will reboot and will now be accesible using the default IP

Pressing it three times will enable SSH. This is required if you have a problem with your StingRay – You may be requested to do this by a support engineer.

How do I manually shut down the StingRay?

To shut down the StingRay via the Front Panel, press the power button once. It will beep, pause, and beep a few more times before shutting down.

The power button is located on the front for the white StingRays and on the back of the black fronted ones…

PLEASE NOTE: Pressing the power button more than once can change settings – Only press the button once…

Please see the following FAQ for more information on the functions of the Power Button - http://www.hermstedtstingray.com/faqs/the-power-button/

How to shut down / reboot the StingRay via the web interface?

To shut down or reboot the StingRay using the web interface please follow the instructions below:

1) Log into the web interface as an administrator.

2) Navigate to Hardware Configuration.

3) In the bottom right corner, select either Reboot or Shutdown

A message will pop up to confirm.

StingRay Internal Integration (18)

My Regular Expression is showing in the External Web Interface, why?

If you have created a regexp in a Job Ticket, saved it and find External Users see the regexp in the field where they’re supposed to input text, there are two things you need to make sure of:

1) As you can see above, Optional is unchecked. Regexp must be mandatory!
2) Additionally, all regexp snippets must be surrounded by (parentheses).

As long as these two requirements are fulfilled the regexp should perform as you’d expect.

If you’re still having issues, please contact technical support.

Job tickets show up blank when I sign in, why is this?

Does this look familiar?


When you create a StingRay Job Ticket, if there are blank fields inserted anywhere within the form, it may break and cause the ticket to display incorrectly when you or your customer signs in via the external interface. This happens, in particular, when a blank option is inserted into the “select” ticket type.

This is not to say that some fields cannot be left blank! The image below may help in clearing up any confusion.
In the image below, green ticks indicate a field that may be left blank, while red crosses indicate fields which must be filled in. The below fields only list categories that have the option to insert text. All others (check box, date etc) need a name and XMLKey, but any other options are up to you.

If for any reason a blank field is accidentally inserted into the “select” category, please select it from the drop-down menu and then click the delete (bin) icon.

If you require any assistance at all, please contact support.



Forwarding to multiple internal servers

We recently had a request by a customer to forward incoming files to two internal servers.  This is not something which StingRay has been designed to do – clearly if you look at the Workflow/Forwarding section you can only enter a single servers details.

This got us thinking that we could surely come up with a way to achieve this by forwarding files back to StingRay and StingRay then sending out to a group of addresses being in this instance, two internal servers.  It worked, although its not something that we will support we can show you how to achieve it

Follow these instructions….

Set up two OUTGOING address entries on StingRay, these should be by FTP to your internal servers and name them something obvious like workflow 1 and 2.

Create an Address Group from the top right corner of the Address book page selecting NEW GROUP and add the two addresses you’ve created to this group.  Call the group name something short and simple e.g. workflow.  Ensure the button “Visible for data server (outgoing jobs)” is ticked.

Go to Mailbox/Forwarding and create a new Forward.  Essentially what we’re looking to do is to forward files back to the StingRay which will then send out to the two address entries previously created.  See the screenshot below paying close attention to the “PATH” where the middle variable (aworkflow) is your Address Group name.  Click on the TEST button to ensure that it authenticates correctly.

 Image Missing “Workflow Forwarding Settings”

Finally you can then assign this Mailbox forwarding to any Incoming Address entry in the top General Information section – see Mailbox below:

Image Missing “Address Book Configuration” 

Once all these steps are in place you can then send files to yourself to the Incoming Address book entry you’ve assigned the Mailbox to.  This will in turn send the files back to the StingRay Group you’ve created and create “two” Outgoing jobs (this may take about a minute).  Once it has done this it will then send the files to the locations specified and bingo you have your files on both of the servers you need them on.  This Mailbox can be associated with any number of incoming address book entries.

StingRay Notifications (5)

When I send files in, I want to know what was uploaded. How do I do this?

For the reasons you cannot see what was uploaded when you disconnect and reconnect to a StingRay, view  Why can’t external users see their files after reconnecting?.

The most efficient way of keeping track of files you upload to the StingRay is with a notification.
Following the steps below, you can set the StingRay to send a notification email after every session with a detailed summary of the files uploaded:

A) Address book entry modification:

1) Log into the web interface as an administrator.
2) Navigate to Address Book.
3) Select the address book entry you wish to receive notifications after having sent a file/files in.
4) Click Edit.
5) In the address book entry, under General Information fill in the Email field and under Notification select Email.
6) Click Save.

B) Notification Setup modification:

1) Navigate to Notification Setup.
2) Click Edit.
3) Check “External” on the “On Receipt” category.
4) Click Save.

Now when a user sends a file/files into the StingRay, they will be notified of the file(s) that were uploaded via email.

How do I set up notifications for sending and receiving files?

There are three levels of email notification on the StingRay; at an admin level, at a group level and at a user level.

Admin / Protocol / Receiver Level

1) Log into the Internal Web Interface as an administrator
2) Go to Receiver Setup menu
3) Click on any receiver (FTP for example)
The local users at the bottom of the page who are moved from the left to the right will receive email notification for all incoming FTP packages, however this is dependent upon the Notification Setup.

Group Level

1) Log into the Internal Web Interface as an administrator
Go to Mailboxes/Forwarding
Click new to create a new mailbox (Studio for example)
4) Go to Address Configuration for this Mailbox
5) Move address(es) to the right hand window
6) Move the local users who require notifications for the above address(es) to the right
7) Save
This will notify local users (internal users) of jobs for the sites listed and is dependent on the Notification Setup options.

Individual user Level

1) Log into the Internal Web Interface as administrator
Go to Address Book
3) Enter the address you want a notification for
4) Within the top section “General Information” enter the email address of the external customer and/or the internal user who needs notifying when jobs are received from this site.

How do I edit notifications sent when I send or receive a file?

If you’re not happy with the default notifications you receive when sending or receiving files (depending on what occasions you have chosen to be notified on) there is a simple way of editing the notification, and with preset short codes you can add at your will, the notifications will always be dynamic.

To edit the notification, follow these steps:

1) Log into the Internal Web Interface as an administrator.
2) Navigate to Notification Setup.
3) Click Edit.
4) On the notification you wish to edit, select the pencil icon next to the checkbox
5) Once you have clicked the icon, you will be taken to another screen which gives you the ability to edit the notification to exactly how you want it, using the short codes below.
6) When you are finished click save.


Here are the short-codes, and their meanings as seen within the Notification Setup page. If you see one not on this list, please feel free to get in touch.

<?SRNAME?> – This is the name of the StingRay as show in Site Information.

<?ADDRESS?> – This is the address listed in Site Information, likely to be the address of your company.

<?TIME?> – The current time when the notification is sent.

<?DATE?> - The current date when the notification is sent.

<?VALIDUNTIL?> – The time and date of the file’s expiry.

<?RECIPIENT_NAME?> - The name of the recipient of the notification as defined in the Local User settings.

<?LF?> - Equivalent to a new line.

<?URL?><?/URL?><?LABEL?><?/LABEL?> - Add a hyperlink to the notification.
Go to <?URL?>www.hermstedtstingray.com<?/URL?><?LABEL?>StingRay home<?/LABEL?>

StingRay Reporting (1)

Does StingRay provide auditing and reporting?

Providing an audit of all files sent, received and connections from customers to download files is a key element in StingRay providing enterprises with clarity of information expected from a managed file transfer solution.

A simple text file can be exported from StingRay in a tab-delimited format for use within your accounting systems or for analysing the volume of data sent and received with key trading partners.

To download a log file;

1) Log into the StingRay via the internal web interface.

2) Go to the System Management menu and click on Import/Export.

3) Scroll down the screen to Export of Transfer Logs.

4) Complete what information you require and click Export.

StingRay Security (1)

Setting up an SSL Certificate for StingRay (HTTPs)

StingRay supports SSL certificates and can work over a HTTPs connection. This is, however, something Pro2col will need to install for you. If this is something you require, the outline of the process is written below.

In order to install an SSL certificate on your StingRay, we will first need the following information:

Country Name: (EG: Great Britain)
State or Province: (EG: Oxfordshire)
Locality or City: (EG: Oxford)
Company: (Your company name)
Organisational Unit: (A department responsible for the StingRay in your company)
Common Name: (EG: ssl.hermstedtstingray.com)

Once we have this information, we can generate a CSR (Certificate Signing Request) file. When you receive this file, please send it to your SSL Certificate provider to have an SSL Certificate created.

Note: You will be required to verify that you own the domain. A verification email will be sent to the Whois registered email address so please make sure the email address registered there is an email account of someone within your organisation who will be able to reply to it.

After receiving an SSL certificate back from the SSL Certificate provider, you will need to send it to us for installation.
When you send the SSL certificate to us, please also enable HTTPs on your StingRay. This can be done by doing the following:

▪    Navigate to Network configuration

▪    Click Edit

▪    Enable HTTPs under External Webaccess

In order to generate the CSR file and install your SSL certificate, we will require an SSH session on your StingRay. As such, in addition to the above required information, please also send the public IP and the serial number of your StingRay to allow us to log in as quickly and efficiently as possible.

For information on how to enable SSH, please see the following FAQ:

StingRay Support (9)

I need remote support, how do I set it up?

If you require assistance or have been advised to enable SSH, there are a couple of prerequisites that need to be adhered to.

You need to have SSH (port 22) open on your external firewall. If you cannot enable this, we will need to set up a TeamViewer support session. See the bottom of this page for TeamViewer instructions.
Once you have either TeamViewer or SSH enabled, you need to enable SSH on the StingRay unit. There are two ways to do this, as follows.

Option 1 is under normal circumstances.
1) Log into the StingRay as an Administrator and navigate to Network Configuration.
2) Scroll to the bottom of the page and click “Edit”.
3) Make sure network type is set to “internal and external”
4) Click “Save”
5) Click the red SSH light. It should turn green.
6) SSH is now enabled.

Option 2 is for if the web interface is not available:
1) On the front panel press any button to bring up the menu on the stingray
2) Press the button under setup.
3) Press the button under IP.
4) Set the IP to
5) Press the button under the key.
6) Now it will give the the options to ssh via SSH/IP OR SSH/ISDN. For SSH support over the internet, press the button under SSH/IP.
7) SSH is now enabled.

Remote support via Teamviewer:

If you cannot enable SSH on the firewall, we can still connect via TeamViewer to gain access to the StingRay.
- Navigate to http://www.hermstedtstingray.com/services-support/remote-services/
- Click the image for the operating system you have
- Allow the file to download and open it once downloaded
- The TeamViewer window should open and give you both a user ID and password.
- Give both of these codes to your support agent.

The support agent will assume control of your computer.


Do you use Windows? 

To allow SSH connections from Windows machines, we require Putty.

You can get it here: Putty download link
Download the version best suited to your system (x86 is most common).

How do I get a Log File from StingRay? (Trace Log)

In some cases we require a log file to see exactly what’s happening on your system when you’re trying to send or receive a job. It is a relatively easy task and can be done as follows:

1) Log into the StingRay’s internal interface as an administraotor

2) Navigate to Hardware Configuration

3) When we ask for the trace log, we will request one of the following:  If we have not, please ask.

Browser Utilities
Servlet Utilities

4) To the right of the agent you have been asked to log, click Start.

Now the StingRay is logging its’ actions as you carry out tasks. If you send or receive a job as you usually would it will log exactly what’s happening inside the StingRay while this is happening, and any errors that may be popping up.

Once you have finished the task you wished to carry out, follow these steps:

1) Navigate to Hardware Configuration

2) To the right of the agent you were asked to log, click Stop*.

3) To the right of the agent you were asked to log, click Export.

4) Save this to your local computer.

Once it is saved, please email it to support@pro2colgroup.com so we can troubleshoot your issue.


*It is extremely important you click stop after running only the tasks you were required to do. Leaving the log running will very quickly completely fill your drive and overload the StingRay.

I’ve forgotten my password, how do I reset it?

StingRay user:

If you’ve forgotten your password, please request your StingRay Administrator change it.

StingRay Administrator:

If you have forgotten your password, please contact support on support@pro2colgroup.com.
