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:
~ ping -c 4 grex.org
PING grex.org (75.61.90.157) 56(84) bytes of data.

--- grex.org ping statistics ---
4 packets transmitted, 0 received, 100% packet loss, time 3105ms

I do not have root privileges on that system.
Code:
~ telnet 75.61.90.157 22
Trying 75.61.90.157...
Connected to 75.61.90.157.
