something on port 98?



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hey all.  I'm seeing odd results when I portscan my server from a remote
host.  nmap is indicating that port 98 (the dreaded linuxconf port) is
in a filtered state.  I have never ever ever installed linuxconf.  I
know my ipchains rules have nothing to do with this, as I just flushed
all the rules, tried the portscan again, and saw the same results.

fuser does not show any process listening on port 98.  I built a new
fuser executable from trusted source (the Debian potato sources, freshly
downloaded) and still saw nothing on that port.

telnetting to that port from a remote host hangs while trying to
establish the connection.  telnetting from the localhost gives a
connection refused message.

I doubt it's a sign that the box has been cracked, but I suppose it's
conceivable.  I'm stumped.  Can anybody offer an explanation?

thanks.
noah
