    SSH to Extreme Switch fails, "Server signature does not match"


      Hi all,


      I'm trying to configure our SolarWinds CatTools 3.6 (Enterprise) to backup the configuration of our Extreme Switches (Summit X350).

      Unfortunately I get an error when trying to connect to the switch, the following is from the Info Log:

      "Failed to connect to <ip address>. Reason: (30015) Server signature does not match.. Giving up after 3 connection attempts."

      These are new switches so there shouldn't be any old signatures, and that shouldn't be the problem anyway, right?

      I can connect to the switch with putty.

      I have three different ssh connection methods to choose from in the device configuration; SSH2, Extreme SSH2 and SSH2-nopty. I am a bit unsure about the difference between them but I have tried them all without succeeding.

      Telnet works (if I allow it), but we need to use SSH.

      Does anyone recognise this problem?

      Please let me know if you need any more information from me.


      Best regards,
