    Connections to Linux servers fail

      Hello all.

      An issue came up with a client running under WinXP tries to connect to a Linux system using the Linux systems hostname if the name contains an underscore (_).

      Setup:
      Debian Etch 4 Linux server
      Samba for name resolution
      Jboss 4.2.3
      Jboss-remoting 2.4.0.SP1

      The client RCP client knows the name of the Linux server and tries to connect to it, but fails with a RuntimeException:

      Caused by: java.lang.RuntimeException: server_name.domain.it

      This seems to only affect the remoting stuff as no other system has issues.
      A simple (beanshell) lookup works fine: 
      print(InetAddress.getByName("server_name"));


      I know that the hostname should not have an underscore but remoting seems ATM the only thing that has problems with this.

      What can I do besides not using underscores?
      Thanks
