Zombie pop3s (and imaps?) processes in connect state

by Christian Balzer

Hello, we've been using perdition as a pop3/pop3s/imap/imaps proxy for about four years now, first with Debian Sarge package and now under Etch. And throughout this time I've seen pop3s (and from the looks of it the same happens with imaps) processes stuck in connect, like this: --- 16836 ? S 5:31 0 120 32179 2204 0.0 perdition.pop3s 28070 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect 7782 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect 24468 ? S 0:00 0 120 32311 1568 0.0 \_ perdition.pop3s: connect 14180 ? S 0:00 0 120 32311 1568 0.0 \_ perdition.pop3s: connect 13503 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect --- They never die off, keep the connection open, there is no traffic and the other end might be long gone. Last trace in the logs is always like this: --- Feb 5 22:05:16 pp11 perdition[7782]: Connect: hi.mi.ts.u->203.216.5.113 --- It must be something related to the SSL'ness of these service, since I'm not seeing this happening ever for imap/pop3. Alas a lot of people do use TLS with those, so it's not a generic SSL issue. Maybe the master process could kick a child handling connections in the head after "timeout" seconds in connect state? If more information is needed I can try to provide it, but note that with a rate of roughly 35 pops per second I'm a bit weary to turn on debugging. ^_- This may or may not be related to another SSL related issue, which will be for the sake of making searches in the archive more likely to find good keywords in a separate mail.

New perdition release?

by Thomas Vogt

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello Are there any plans for a new perdition release? With the changeable ldap version via configuration file is at least one useful change in the repository. Maybe experimental ipv6 support could also be added. I'm also the FreeBSD maintainer of the perdition port and i would like to bring this in the ports tree without maintaining too many local patches.

updated IPv6 patches for perdition and vanessa socket lib

by Antonio Querubin

The original IPv6 patches I submitted earlier didn't build on Linux systems. Attached are updated IPv6 patches which have been tested successfully in inetd mode on CentOS 5. However, in daemon mode under CentOS, sometimes the spawned process will segfault. I'm still trying to determine whether this is due to a problem with the patch itself or the way I've built the RPM. Both daemon mode and inetd mode under FreeBSD seems to work reliably though so I suspect this problem is something peculiar to Linux which I've overlooked. In any case, I'm putting these updated patches out in the hope of getting additional data back from anyone running perdition in daemon mode on Linux systems. Antonio Querubin whois: AQ7-ARIN

bug: Partial results from DB lookup causing parsing problems

by Simon Fraser

Hi folks, I'm newly subscribed to this list, and while I've searched for a mention of this before and come up with nothing, I apologise if I'm duplicating a report. I'm using perdition-1.17.1 with perditiondb_ldap. Due to the nature of our site, some users will have a mailhost configured in here, and some will not. I am hoping to use the outgoing_server configuration option as a default should the server return a partial response, since one of our existing systems will break if we started adding this to all the currently empty fields. This works if the user had a mailhost set, but was refusing to use the outgoing_server option if they did not, instead attempting to connect to the person's username, treating it as a hostname. Omitting the port works whether the server is set or not. I have tracked down this problem to user_server_port_strn_assign in getserver.c. This function appears to be dual-purpose, used for both parsing the outgoing_server option in the configuration file, and also for parsing the string returned by dbserver_get. Since these have a slightly different format (hostname[:port] vs username[<delimiter>hostname[:port]]), it gets confused when the string returned from the DB doesn't contain a server. It falls through into its configuration parsing option at the end, setting (*usp)->server to (*usp)->user (the start of the string), and so the connection attempts gethostbyname(username).
