Can't establish outbound ssh connection on an OpenBSD system

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.

it looks like I can't ping to that OpenBSD system from some other systems. Here is the output from my linux fedora:

Code:
