Log question: "Address already in use"

Post by Dariusz Kosti » Sun, 13 Feb 2000 04:00:00



Hi All,
Looking through messages file in /var/log I have found the following
messages

Feb 11 09:45:11 abc inetd[26039]: linuxconf/tcp: bind: Address already
in use
Feb 11 09:45:11 abc inetd[26039]: auth/tcp: bind: Address already in use

Feb 11 09:45:11 abc inetd[26039]: pop-3/tcp: bind: Address already in
use
Feb 11 09:45:11 abc inetd[26039]: ftp/tcp: bind: Address already in use

   What does this exactly mean and what should I do to resolve the
problem ?
   I will appreciate any help.

Darek

You probably have running stand-alone daemons for the mentionend
services. While some daemons are started by the super deamon inetd some
can be started without. You'll need wether to stop the stand-alone
daemons or to comment out the lines for these services in
/etc/inetd.conf.

Only one process can listen on a pair of (address, protocol, port) at
once in order to make the distribution of connections to processes
possible. 0.0.0.0 is used for all IP addresses of the machine. If
another process does want to listen there too it does have to call
bind() which then will return a error code translating into the text
"Adress allready in use".

1. Identd "bind: Address already in use" messages in /var/log/messages

Looking through my logs today I found that there
were almost 900 entries of the following:

Feb 13 03:30:35 gateway inetd[489]: auth/tcp:
bind: Address already in use

of course the times were all different but exactly
10 minutes apart. All of this in the past 7 days.

I'm running a simple redhat 6.1 install stripped
down to basically act only as a firewall w/ IP
Masquerading.

Any info about this would be helpful
