Hi! I have the following version of courier-pop3 server: 0.53.3-5 (debian -etch). One of my clients (behind NAT) started exhausting MAXPERIP limit. After some investigation I finded that some of his connections stay alive for 7200 seconds (tcp_keepalive_time). Then there is sent a keepalive packet without response. Then there is a 9 probes (tcp_keepalive_probes) each after 75 seconds (tcp_keepalive_intvl). And then the connection is terminated. Those keepalive packets leaves my router.
I also noticed that when I telnet to my server on 110 port and do nothing the connection is alive forever. I read from this list that inactive connections are dropped after 5 minutes. Not in here. I can't change tcp parameters because they would have influence on whole system. How to drop inactive pop3 connections ? I have already set MAXPERIP. Sorry for my poor english. ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ courier-users mailing list [email protected] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
