New Server 2019 with Sophos Enterprise Console client status not shown

Teun Pleunis

We have a new installation of server 2019 standard (which is a fileserver and domain controller) with Sophos Enterprise Console.

As a starting point we have created a GPO to make sure all client computers have the required services turned on and ports open in the firewall. The clients already had Sophos installed (the old Sophos Enterprise Console server has been retired). All clients were migrated to the new domain. Using the Enterprise Console on the new server we re-deployed Sophos to all clients. This is succesfull and I checked that the clients are getting their updates from the new server. For some of these clients I also tried installing Sophos manually (from \\SERVERNAME\SophosUpdate\CIDs\S000\SAVSCFXP) , this works without issues.

However the only client that is reporting it's status back to the Enterprise Console is the local Sophos agent installed on the server itself. Even after turning off the firewall, server reboots etc.

When looking at the client the router shows the following errors in the log (trace logging is enabled);

So Sophos appears to have difficulties with the certificate. However when I connect OpenSSL with the CAC.pem cert it verifies ok:

The CertManager on the Sophos Enterprise Console server shows no entries in the current log which is strange because 20 clients are constantly trying to connect...

    The IOR string can be decoded using catior.org for one. 

    From the client log provided:

                    wchar conversion code sets: 

      TAG_SSL_SEC_TRANS port = 8194 supports 166 requires 134

    So the client is trying to get the IOR off the server of port 8194 and is getting back 127.0.0.1 port 8194.  So the client router then tries to connect back to itselft on port 8194.


    I thought there was detection in the router for preventing the IOR from containing a loopback address.  Maybe - https://community.sophos.com/kb/en-us/133590 ?

    Can you configure the server's router's IOR to be the IP address as per the following steps on the management server:

    1. Go to HKLM\SYSTEM\CurrentControlSet\Services\Sophos Message Router\ImagePath and change the value data to

      C:\Program Files\Sophos\Remote Management System\RouterNT.exe" -service -name Router -ORBListenEndpoints iiop://<SEC server IP address>:8193/ssl_port=8194

      I assume this is to be:       192.168.178.10 if this is the static IP of the management server. 

      Does it have a static IP?  If not you can override the address in the IOR to be a FQDN.
      https://community.sophos.com/kb/en-us/50832 details how you can use the switches hostname_in_ior and ORBDottedDecimalAddresses in the router args to get a adress in the IOR the clients will use.

    2. Change the value data of the following registry keys to -ORBListenEndpoints iiop://<SEC server IP address>:8193/ssl_port=8194:

      32-bit: HKLM\SOFTWARE\Sophos\Messaging System\Router\ServiceArgs
      64-bit: HKLM\SOFTWARE\Wow6432Node\Sophos\Messaging System\Router\ServiceArgs

      This ensures that the changes made persist even with any RMS updates or reinstallations.

    3. Restart the Sophos Message Router service.

    If you then look at the IOR string in catior.org, you should see the IP address in it rather than loopback.  This will be the IP the clients read off the servers IOR port (8192) so they can connect back to it on port 8194.

    You can think of the IOR string that is put out on port 8192 as a signpost telling the connecting router (client) how to get to port 8194.  The first thing is to get an IP in there that the server and clients can use to get back to the server.

    Hope it helps.

    Regards,

    Jak

    Hi Jak,

    Thank you very much for this. I was on the right track with the IOR but couldn't find a way to translate it so you provided the missing pieces of the puzzle.

    I still think it is strange that with a new installation this problem occurs as it should have used the static ip-address or servername from the beginning automatically.

     

    After the registry change (adding the static server ip) and restart of the message router service the agents came back online almost instantly. So very happy with this.

    Thanks a lot!!! At least I can get some sleep tonight :)

    Glad the information helped you figure it out.

    Regards,

    Jak
