[Dovecot] trouble setting up director, "invalid argument" for connect() call

4 Oct 2011 · *too*


      Hi Timo & everyone,
I'm trying out a 2-node director setup, but I keep getting the following
error:
Oct  3 16:11:29 imapdir1 dovecot: master: Dovecot v2.0.15 starting up
(core dumps disabled)
Oct  3 16:11:34 imapdir1 dovecot: director: Error:
connect(132.198.100.150:9090) failed: Invalid argument
Oct  3 16:11:41 imapdir1 last message repeated 3 times
Both nodes report this error.  The director on each node is listening on
port 9090 just fine:
...
[root@imapdir1 ~]# nc imapdir2 9090
VERSION director        1       0
ME      127.0.0.1       9090
...
[root@imapdir2 ~]# nc imapdir1 9090
VERSION director        1       0
ME      127.0.0.1       9090
"doveadm director ring status" always reports failure of the peer:
...
[root@imapdir1 ~]# doveadm director ring status

Has anyone else seen this?
FWIW, a single-node director works fine, proxying IMAP, LMTP and POP.
I'm guessing I have a broken config, but if I do I can't figure it out.
Hope I'm not missing something *too* obvious...
Here's doveconf -n from imapdir1:
# 2.0.15: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.18-274.3.1.el5 x86_64 Red Hat Enterprise Linux Server
release 5.7 (Tikanga)
base_dir = /var/run/dovecot/
director_mail_servers = penguina.uvm.edu penguinb.uvm.edu penguinc.uvm.edu
director_servers = imapdir1.uvm.edu imapdir2.uvm.edu
lmtp_proxy = yes
login_trusted_networks =
132.198.101.211,132.198.101.212,132.198.101.213,132.198.101.214,132.198.101.215,132.198.101.216,132.198.100.45,132.198.100.46,132.198.100.47
passdb {
args = proxy=y nopassword=y protocol=smtp
driver = static
}
service auth {
unix_listener auth-userdb {
group = mail
mode = 0660
user = dovecot
}
}
service director {
fifo_listener login/proxy-notify {
mode = 0666
}
inet_listener {
port = 9090
}
unix_listener director-userdb {
mode = 0600
}
unix_listener login/director {
mode = 0666
}
}
service imap-login {
executable = imap-login director
}
service lmtp {
client_limit = 1
inet_listener lmtp {
port = 24
}
unix_listener /var/lib/dovecot/lmtp-socket {
group = root
mode = 0600
user = root
}
}
Best,
Jim
