Hi,

There are quite a number of possibilities here, but lets start with the simple things first.

Can you ping the OpenBSD system from another system.
What result do you get if you run the ssh commands as the root user.
From one of your Linux system try telnet host_ip port# so something like telnet 123.123.123.123 22 and post the output.

It is also worth running a traceroute from your Linux system and post the output. For reference you can also run a traceroute to googles servers with traceroute 8.8.8.8 - a comparison of the results may give you a hint.

You could also compare the /etc/networks file with a working system, in case there are any routes defined.

You could also post the output of ifconfig -a check that there is a gateway address assigned.

Regards

TRACEROUTE6(8)						 System Manager's Manual: iputils					    TRACEROUTE6(8)

NAME

       traceroute6 - traces path to a network host

SYNOPSIS

       traceroute6 [-dnrvV] [-i interface] [-m max_ttl] [-p port] [-q max_probes] [-s source] [-w wait time] destination [size]

DESCRIPTION

       Description can be found in traceroute(8), all the references to IP replaced to IPv6. It is needless to copy the description from there.

SEE ALSO

       traceroute(8), tracepath(8), ping(8).

HISTORY

       This program has long history. Author of traceroute is Van Jacobson and it first appeared in 1988. This clone is based on a port of tracer-
       oute to IPv6 published in NRL IPv6 distribution in 1996. In turn, it was ported to Linux by Pedro Roque. After this it was kept in sync	by
       Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>. And eventually entered iputils package.

SECURITY

       tracepath6 requires CAP_NET_RAWIO capability to be executed. It is safe to be used as set-uid root.

AVAILABILITY

       traceroute6  is part of iputils package and the latest versions are  available in source form at http://www.skbuff.net/iputils/iputils-cur-
       rent.tar.bz2.
