Hello,
I have discovered a strange behaviour with director proxying...
I have a user, its assigned server is 155.54.211.164. The problem is
that I don't know why director sent him yesterday to a different server, because my server was up all the time. Moreover, I'm using poolmon in director servers to check availability of final servers and it didn't report any problem with the server.
I have two load balanced director servers. Logs at these servers are:
logs directing him to the correct backend server Jun 28 08:38:18 myotis42 dovecot: auth: Debug: master in: PASS#0111#011<user>@um.es#011service=lmtp#011lip=155.54.211.185#011lport=24#011rip=155.54.212.168#011rport=52255 Jun 28 08:38:18 myotis42 dovecot: auth: Debug: static(<user>,155.54.212.168): lookup Jun 28 08:38:18 myotis42 dovecot: auth: Debug: master out: PASS#0111#011user=<user>#011proxy#011proxy_timeout=150 Jun 28 08:38:18 myotis42 dovecot: lmtp(15889): Debug: auth input: user=<user> proxy proxy_timeout=150 host=155.54.211.164 proxy_refresh=450 Jun 28 08:39:59 myotis42 dovecot: auth: Debug: master in: PASS#01118#011<user>@um.es#011service=lmtp#011lip=155.54.211.185#011lport=24#011rip=155.54.212.166#011rport=40008 Jun 28 08:39:59 myotis42 dovecot: auth: Debug: static(<user>,155.54.212.166): lookup Jun 28 08:39:59 myotis42 dovecot: auth: Debug: master out: PASS#01118#011user=<user>#011proxy#011proxy_timeout=150 Jun 28 08:39:59 myotis42 dovecot: lmtp(15361): Debug: auth input: user=<user> proxy proxy_timeout=150 host=155.54.211.164 proxy_refresh=450
now, the other director server sends him to an incorrect backend server Jun 28 09:01:12 myotis41 dovecot: auth: Debug: static(<user>,155.54.66.38): lookup Jun 28 09:01:12 myotis41 dovecot: auth: Debug: static(<user>,155.54.66.38): Allowing any password Jun 28 09:01:12 myotis41 dovecot: auth: Debug: client out: OK#01134556#011user=<user>#011proxy#011proxy_timeout=150#011pass=<hidden> Jun 28 09:01:12 myotis41 dovecot: auth: Debug: static(<user>,155.54.66.38): lookup Jun 28 09:01:12 myotis41 dovecot: auth: Debug: static(<user>,155.54.66.38): Allowing any password Jun 28 09:01:12 myotis41 dovecot: auth: Debug: client out: OK#01152763#011user=<user>#011proxy#011proxy_timeout=150#011pass=<hidden> Jun 28 09:01:12 myotis41 dovecot: imap-login: proxy(<user>): started proxying to 155.54.211.162:143: user=<<user>>, method=PLAIN, rip=155.54.66.38, lip=155.54.211.186 Jun 28 09:01:12 myotis41 dovecot: imap-login: proxy(<user>): started proxying to 155.54.211.162:143: user=<<user>>, method=PLAIN, rip=155.54.66.38, lip=155.54.211.186 Jun 28 09:01:13 myotis41 dovecot: auth: Debug: static(<user>,155.54.66.38): lookup Jun 28 09:01:13 myotis41 dovecot: auth: Debug: static(<user>,155.54.66.38): Allowing any password
Now, the first director sends him to the incorrect one too Jun 28 09:33:50 myotis42 dovecot: auth: Debug: master in: PASS#01132#011<user>@um.es#011service=lmtp#011lip=155.54.211.185#011lport=24#011rip=155.54.212.168#011rport=46830 Jun 28 09:33:50 myotis42 dovecot: auth: Debug: static(<user>,155.54.212.168): lookup Jun 28 09:33:50 myotis42 dovecot: auth: Debug: master out: PASS#01132#011user=<user>#011proxy#011proxy_timeout=150 Jun 28 09:33:50 myotis42 dovecot: lmtp(17284): Debug: auth input: user=<user> proxy proxy_timeout=150 host=155.54.211.162 proxy_refresh=450
I haven't found any error log for the correct backend server between the correct redirection and the incorrect one. In fact, I have lot of logs of other users directed to it, and logs of the same director directing connections to the correct server.
