[gentoo-user] Need help discovering what's using a port (for cvsd)

[Michael Sullivan]

A few years ago I was working on a programming project.  I installed a
cvsd server on our server box and checked in/checked out the project
whenever I felt like working on it (it would have gotten majorly screwed
up if the only copy of the project lived on my personal workstation -
hence using cvsd).  Anyway, I got busy with other things and forgot
about that particular programming project.  At some point over the last
few years, cvsd got unmerged.  I remerged it today and have been trying
to get it to work.  I checked the repository directory and the files I
need are still there.  I can't get the server to start.  I tried
running /etc/init.d/cvsd start and it failed with the [!!] thing.  I
catted the script and saw that the executable for the cvsd server lives
at /usr/sbin/cvsd, so I tried calling it directly:
carter log # /usr/sbin/cvsd --debug
cvsd: debug: reading config file (/etc/cvsd/cvsd.conf)
cvsd: debug: done reading config file
cvsd: debug: cvscmd: /bin/cvs
cvsd: debug: cvsargs[0]: cvs
cvsd: debug: cvsargs[1]: -f
cvsd: debug: cvsargs[2]: --allow-root=/root
cvsd: debug: cvsargs[3]: pserver
cvsd: debug: cvsenv[0]: HOME=/
cvsd: debug: cvsenv[1]: PATH=/bin
cvsd: debug: cvsenv[2]: SHELL=/bin/sh
cvsd: debug: cvsenv[3]: TMPDIR=/tmp
cvsd: debug: cvsenv[4]: CVSUMASK=027
cvsd: version 1.0.7 starting
cvsd: debug: binding 0.0.0.0 2401 family=2 socktype=1 protocol=6
cvsd: listening on 0.0.0.0 2401
cvsd: debug: binding :: 2401 family=10 socktype=1 protocol=6
cvsd: bind() failed: Address already in use
cvsd: version 1.0.7 bailing out
carter log # netstat -anp | grep 2401
carter log # 

Nothing.  I hope I'm using the netstat command correctly.  I wrote in to
a linux list years ago asking how to find out which process is using a
port, and they said to grep `netstat -anp` for whatever port I was
looking for.  Anyway, when I ran netstat -anpv, I got some errors:

netstat: no support for `AF IPX' on this system.
netstat: no support for `AF AX25' on this system.
netstat: no support for `AF X25' on this system.
netstat: no support for `AF NETROM' on this system.


I assume these are kernel options, but without knowing specific symbol
names, I'm not sure how to compile them into the kernel.  Can anyone
give me any advice on this situation?

I think if you don't have support for those protocols the chances of a
program using them is probably zero. :) FWIW i get the exact same
messages. I don't think it is meaningful.

I use a similar command (omitting all the unix sockets stuff): netstat
-lnp --inet

With regard to your original problem, try to edit the cvsd.conf and
specify an actual IP address to listen on (instead of 0.0.0.0 or * or
however it is defined there) and see if that helps.

Now I've got the server running, but I can't connect to it:

michael@camille ~ $ cvs login
Logging in to :pserver:michael@carter.espersunited.com:2401/root
CVS password: 
cvs [login aborted]: connect to
carter.espersunited.com(192.168.1.2):2401 failed: Connection refused

My .cvspass looks kinda weird too:
michael@camille ~ $ cat .cvspass
/1 :pserver:michael@carter.espersunited.com:2401/root Ah0 %0]y?

Is this right?

Hmm, does cvsd use inetd? maybe it needs to be added to allowed port
list or something like that.

This line in the config file:

Listen 127.0.0.1  2401

needed to be changed to this:
Listen 192.168.1.2 2401

And now it works
