A question on ip / port binding and udp protocol

that comes from the resolver lib, used by async DNS module

same effect with many (virtually all) ircds

A question on ip / port binding and udp protocol

2005-02-13T18:19:52-04:00

good question... I wonder what they are used for anyway. I have 3 (UDP listenings) each bot. 2 bound to 0.0.0.0 and 1 to 127.0.0.1 @_o. Are they some kind of intern loopback/interface between modules?

A question on ip / port binding and udp protocol

Lo all,

I'm trying to clear up the listening ports on my fedora server, and making sure that all the processes only bind / listen on the right IP. Now this setting in the conf:

Code:

set my-hostname "some.isp.com"set my-ip "111.111.111.111"

Will bind it to one ip. Yet when I do a netstat command, I'm still getting a udp as shown not to be bound to a specific IP, as below:

Code:

[root@moo home]# netstat -a -e |grep jacktcp        0      0 111.111.111.111:10065   *:*                     LISTEN      jack       17300      tcp        0      0 111.111.111.111:32882   212.112.132.41:ircd     ESTABLISHED jack       17318      tcp        0      0 111.111.111.111:33172   111.111.111.111:10075   ESTABLISHED jack       90004      udp        0      0 *:32818                 *:*                                 jack       17301

Is this normal for eggdrops? Would some be kind enough to explain exactly whats happening here and why the udp entry is not bound to a specific IP?

Thanks
