Re: [PLUG] determining what programs are using what ports
|
What's funny is, I think the apache install is messed up. Last night
at the meeting someone said they were having issues with ubuntu and
apache...but I thought nothing of it until this morning when I got
here and apache wasn't working.
It appears I have a rogue apache on my hands...
The one listening on port 80 doesn't have php installed, so it works
but it asks me to download the files
When I start another process on 81, php works (looks like this is the
one I configured)
I can't get the one on port 80 to stop! I used /etc/init.d/apache2
stop; killall, and removing with rc-update.d and rebooting...but it's
still there!
Any thoughts?
Thanks!

Randy,
Just an off-hand thought, check for TIME_WAIT in the netstat ouput
for port 80. I believe that one often shows up when you stop and
start a service too quickly. The program using the port is gone, but
the OS is waiting for all communication to end (or something like
that).
netstat -a | grep 80
The man page says:
TIME_WAIT
The socket is waiting after close to handle packets
still in the network.
Also, the man page says using "netstat -l" will give you only the
ports that are being listened on (heh, I learned something by reading
the man pages).
