Hi Guys,
On our main server we are also having this issue. Our network setup is
using some ipip tunnels and the issue described happens only from the
master when talking to a computer on the other end of a tunnel.

Haven't checked access from the console to test the chbind/v_sshd theory
mentioned.

I have tried ssh, traceroute and others and within the strace it is always
returning Invalid argument on the connect() call. I can provide any
information requested that may help. :-)
