are you sure that you are not using an old lsof binary?
does fstat give the 'correct' information?

Hello All

This is my first posting to the list, so if it's off topic please go
lightly on me.

Running lsof on a suspect OpenBSD 2.6 i386 box, patched to the latest (jan
31) patchlevel, I see this:

# /usr/local/sbin/lsof -i | grep ssh
sshd       5249     root    3u  IPv4 0xe0da5b00      0t0  TCP host:ssh
(LISTEN)

sshd      19463     root    5u  IPv4                 0t0  TCP can't read
inpcb at 0x00000000

sshd      32487     root    5u  IPv4                 0t0  TCP can't read
inpcb at 0x00000000

What is that? I suspect they are ssh connections with the other endpoint
hidden somehow. How would someone do this? What would I look for?
