SAV for Linux Outbound Ports Required

Ng ZhiYun

Hi,

I would like to check which are the ports that the sophos AV is using for the update.

Been receiving error message as such:

SSL error.

Failed to replicate from all update sources

I have already open port TCP 443 and 80 , 8192 - 8194

Thanks :)

    Hello Ng ZhiYun,

    this is indeed the Free version? Ports 8192-8194 are only required for the on-premise (SEC) managed install. As it tries to update over HTTPS I'd say this is the Intercept X (aka Central) version 10.

    How did you initially install? Has it worked and then suddenly stopped throwing these errors or did the updates fail from the beginning? I might be wrong but  it looks like  there's some gateway device (firewall) between this machine and Sophos that attempts SSL inspection.

    Yes this is the free version that we install on a linux VM.

    I tried opening the TCP ports for 8192-8194 too but is still receiving the same error.

    Yup it is working previously when i allow all outbound traffic however i would like to restrict the traffic and only allow specific ports if able.

    The traffic is control using a security list as the VM is hosted on cloud

    Hello Ng ZhiYun,

    as said,, ports 8192-8194 are strictly for management and have nothing to do with updating.

    Taking a second ans closer look at the log - the SSL error is perhaps a red herring. The HTTPS connection fails because of the certificate error but it seems the HTTP connection succeeds but throws a Failed to authenticate error. This suggests a problem with the updating credentials not the ports opened..
    Might be worth checking whether updating again works if you allow all traffic.

    Hi,

    Thanks for helping.

    Yup. I tried and tested allowing all traffic and it is able to update again with no error.

    I have also verify that the server is able to reach the internet with 200 response.

    Hello Ng ZhiYun,

    hm, could you show the debug log (like the one above) from the successful update?
