WARNING: '<IP>' unknown

  • I have a host I can ssh to just fine from openssh (Linux), but under cssh I get the following error:

    WARNING: '<IP>' unknown

    (where <IP> is that particular server IP I'm trying to connect to)

    suggestions?

     
    • Is IP an IP address, a hostname or an alias in the .ssh/config file?

      Later versions of cssh cope with ssh aliases, but either of the first two should work without issue.

      What version of cssh are you using on what os?

        Duncs

      I see basically the same thing.

      If I specify an IP address instead of hostname, cssh doesn't get there.  The IP addresses are good - I can ssh to them no problem.  I get:

      WARNING: unknown host <ip address> - ignoring

      cssh -v
      Version: 3.18 (2005/11/28 19:47:37)

      Linux (Gentoo)

      Any ideas?

      I have the exact same problem. SSH to the user@ip works fine - get an error from cssh:

      WARNING: '10.xxx.xxx.xxx' unknown (unable to resolve and not in user ssh config file)

      DNS names do appear to work. I don't have hosts entries for these. For what it is worth, they are on a different subnet.

      And here is the debug output:

      cssh -d aip@10.xxx.xxx.xxx
