[UCLA-LUG] INETD and POP3

[thefonz]

Hey,

Im new to the list but I hang out in #lug (fonz) sometimes.  I was at the
last installfest.  Just though I should introduce myself.  Anyway Ive been
having some trouble with both identd and pop3.   I think the issues may be
some what connected to each other in some way or another.

Im running Red Hat 6.1 on a P60 w/16MB RAM and a 1.27 gig hd.  I use the
machine for IPMASQ and a firewall as well as a httpd, ftp, mail (if i ever
get pop3 working) and dns server.

1) IDENTD

For some reason IDENTD doesn't seem to work.  I have opened port 113 on my
firewall but still nothing.
I think it may be starting up twice because of the errors im seeing in the
/var/log/messages:
This error is constantly repeating.
Oct 31 21:16:46 potsie inetd[969]: auth/tcp: bind: Address already in use

the auth line in my INETD is:
auth stream tcp nowait root /usr/sbin/in.identd in.identd -e -o

netstat doesn't so anything about identd as far as i can tell.


2) POP3

I configured my sendmail server earlier today.  Everything works fine except
for POP3.  Mail has been comming in and going out fine.  Only problem is
when I try to connect to the mail server using a client that supports POP3
it wont connect to download mail.  It sends mail out no problem but it
refuses to download any mail.  Connection never goes through.  At first I
thought it was a firewall issue but then I relelised on my internal network
all connections are accepted so POP3 should work.  To make sure I added an
ipchains rule that let connections on port 110 in.  Still no luck.  I have
restarted INETD about a hundred times. Also the pop 3 line in INETD is:
pop-3   stream  tcp     nowait  root    /usr/sbin/tcpd ipop3d

netstat -a shows this for pop-3:

tcp        0      0 *:pop-3                 *:*                     LISTEN

telneting to port 110 doesn't work either connection never gets through.  I
have tried this by telneting to the localhost, telneting from another
computer on my network as well as remotely from computers on the internet


Thanks for your help,
Ilan

PS here is my full netstat -a if it helps....
