cyrus-murder: backend and frontend/proxy on the same machine?
Hi I'm evaluating cyrus-murder with cyrus 2.2 (sources from debian etch) using the documentation from http://cyrusimap.web.cmu.edu/imapd/install-murder.html and the twiki. Thanks to the good documentation the setup of some basic functionality was straight forward. I'd like to have two servers both as backend and frontend server. Th clients shold connect to server which holds the users backend and see also shared folders from the other server. Is this scenario possible? The documentation describes an installation of frontend-servers without a local backend, but on the other hand it doesn't say that it is impossible.

Hi, i don't know if it's possible with Cyrus 2.2, but it is with 2.3, look for unified murder Quoting Ingo Steuwer <[EMAIL PROTECTED]>: > Hi > > I'm evaluating cyrus-murder with cyrus 2.2 (sources from debian etch) using > the documentation from http://cyrusimap.web.cmu.edu/imapd/install-murder.html > and the twiki.

Look for the -C option for - well, every cyrus executable :) I've had a system running multiple Cyrus instances, frontends and backends, on same physical servers at the same time in production for half a year now. Works perfectly. The unified murder works less than perfectly, or at least did in version 2.3.8. For instance, copying messages from a folder in the mailstore you were connected to a remote folder was impossible, as was copying messages the other way round. (Copying messages between local folders or between remote folders did work.) --Janne Peltonen University of Helsinki > > Quoting Ingo Steuwer <[EMAIL PROTECTED]>: > > > Hi > > > > I'm evaluating cyrus-murder with cyrus 2.2 (sources from debian etch) using > > the documentation from > > http://cyrusimap.web.cmu.edu/imapd/install-murder.html > > and the twiki.

As the result, the Master database is duplicated with every slave resyncing and is wasted with "multistage" mailbox locations like "obolon.kiev.rct-int!obolon.kiev.rct-int!imap.office.rct-int!default aal". Well, I believe that it is possible to use ctl_mboxlist only once in life, upon the murder initial assembling - but this way seems to be just unreliable. > > It is also very much possible to run two separate instances of Cyrus on > one server, with different imapd.confs and cyrus.confs and spool > directories and configuration directories and what-have-you... sieve > directories, which typically reside within the configuration tree.

Re: cyrus-murder: backend and frontend/proxy on the same machine?
Hello all.
I must conclude that all "combined" configurations of Cyrus Murder
servers do not work. Or, more exactly, I did not manage to make them
work despite of many hours of tests and meditation.
"frontend+backend" combination (aka "config: unified") seems to be
completely broken. It is really unable to distinguish local and remote
mailboxes in the single combined database and pushes everything back to
master, with endless database growth. I wrote about it few weeks ago in
same thread.
"frontend+master" combination behaves much better. Nearly all things
work fine: folder access, folder renaming, sieve access. The only broken
thing is subfolder mailbox creation; any user-level "Create" command at
a frontend is not forwarded to a backend but is denied instantly with
"Invalid partition" diagnostics. Basic debugging shows that the
partition is really invalid because proxyd tries to interpret a
networked "server!partition" path as a local partition name and to find
this name in local imapd.conf.
Feb 11 12:58:05 mail imap[18506]: Partition pharmacy.office.rct-int!default
Feb 11 12:58:05 mail imap[18506]: IOERROR: creating directory (null):
Permission denied
So, it looks like that the only working solution is based on "-C" option
and virtual interfaces or other tricks. If we really need to combine
functions in one box, we should use different "imapd*.conf" and
different "configdirectory:" for all three instances - frontend, backend
and master. After that everything works fine.
My setup:
Master+Frontend: two indepentent mupdate instances, one imapd.
SERVICES {
mupdate_master cmd="/usr/local/cyrus/bin/mupdate -m -C
/etc/imap_master.conf" listen=10.0.0.2:3905 prefork=1
mupdate cmd="/usr/local/cyrus/bin/mupdate -C
/etc/imap_frontend.conf" listen=10.0.0.4:3905 prefork=1
imapcmd="/usr/local/cyrus/bin/proxyd -s -C
/etc/imap_frontend.conf" listen="imaps" prefork=2
sieve cmd="timsieved -C /etc/imap_frontend.conf"
listen="10.0.0.4:sieve" prefork=0 maxchild=100
}
Frontend+backend: two independent imapd instances, one mupdate.
SERVICES {
imapcmd="imapd -p 2" listen="10.0.4.1:imap"
prefork=3 maxchild=200
imaps cmd="proxyd -s -C /etc/imap_frontend.conf"
listen="imaps" prefork=1 maxchild=100
mupdate cmd="mupdate -C /etc/imap_frontend.conf"
listen=10.0.4.1:3905 prefork=1
lmtpcmd="lmtpd -a" listen="10.0.4.1:24" prefork=0
maxchild=20
}
Tested with Thunderbird and Squirrelmail clients.
NB: In this specific setup lmtp does not use murder capabilities because
MTA always knows exact backend from LDAP directory. And the whole
purpose of Murder is to join shared folders from different servers and
locations into one list in one IMAP account. No any "load balance", etc.
