ssh wierdness

[spiff () BWAY NET (spiff)]

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?
