Subject: server-to-server-sync project question

[Reply] [ReplyQuoted] [Headers] [Print]

hello everyone, 

i am a proud user of the citadel groupware project for a year now and i am amazed by its robust and light-footed approach to email and groupware functions in general. Now that me and some friends run citadel on a virtualized ubuntu machine the basement of a friend of mine, we would like to have local backups of our emails at home. 

I stumbled upon the synchronisation features of citadel and i am a bit confused.. Here is my/our setup: 

 

CitadelServer:

  • Enterprise Server Hardware
  • Public Static IP
  • LDAP-Server
  • Owncloud
  • Roundcube as Webmailer for Citadel

 

Here is what i would like to do, maybe you could give me a feedback if that is even possible:

I would like to sync the private rooms of the users (email, contacts, etc.) to specific citadel-servers within a vpn or ssh-tunnel through the web. Every User would have a local backup of their mails, boards etc. on the local citadel-server. 

Outgoing Email is also synced with the main-citadel server due its static ip-adress and good internet-connection. 

So my question consists of different questions:

  1. Is it possible to network citadel instances without opened wan-ports and a dynamic ip-adress (vpn/ssh-tunnel)?
  2. Is it possible to sync the private mail-rooms of the users to the networked citadel-instances?
  3. Is it possible to route email so that it is always sent with the public ip-adress of the "master" citadel-instance?
  4. Will the user-management of the "master" instance which is based on open-ldap scale or do the "slave" instances have to authenticate against the original ldap server?

Thank you very much for your time reading and maybe answering my question - and a big thank you to all the people involved in this great project - which provides simple and fun groupware-capability for a bunch of nerds who are fed up with the ususal enterprise owned cloud-based communication platforms.

Best Regards

Gregor aka. herr_internet

its not just berkeley DB which consumes file handles. rather grep for the PID of citserver than the files.

if many of them is internet connections, there you are.

Mon May 12 2014 01:31:28 EDT from TheOneLaw @ Uncensored Subject: Global Address Book redundant remote Server citadel networking

We did this back in 2010 and it worked very well, version 7.86 (?)

Until just this past month I had not revisited this issue,

 but it would be convenient if we could, or had another way to do it.

 

Now I have been trying to do it again this month and the main server (v8.24) crashes on a 1-minute loop,

 so I had to disable the replication service, which instantly fixed that  particular problem.

I assume I have other issues with the setup, and in light of the deprecation will not worry to much about it anyway.

 

Maybe the old Qmail 'POP Toaster' is what I need to try to set up,

 but fundamentally what we want to achieve is having our guys in the jungle able to access their local server

 complete with all their stored mail even when said server has its link to home broken (as frequently happens)

They will have operations and personnel interconnected over several hundred square kilometers,

 with internet accounts which will need to have outgoing mail held for the moments when the server links are up.

 

A remotely distributed email server with replicated accounts and all their emails stored redundantly.

 

Cheers, anyway,

whatever you do I am sure it will be a step forward.

We currently are using citadel to citadel communication to remove
outside email and use citadel for communication between two domains
only. Would this be interrupted?

We have internet mail off, but use the smtp features for local users
to mail each other, but not outside domains, with the exception of the
other citadel domain. We share a Global Address book, and for all
intensive purposes have the two machines mirroring each other, except
for local mail stores ( they both can function independently as well).

Is this going to be broken?

This was intended to build distributed systems, but I don't know of

In fact, we would like to remove Citadel-to-Citadel networking
entirely in its current form, and replace it with NNTP as the
primary means of sharing rooms between Citadel sites.

If anyone actually has an installation where Global Address Book is
shared and being used for a distributed email domain, please let me
know immediately so we can find an ongoing solution for you. In
the meantime please consider this feature deprecated, and it will
be removed in Citadel 9.

I wouldn't imagine that 177MB for cdb.00 or 423MB for cdb.07 should be too large for the DB engine...I'm sure that the DB files on Uncensored must be far larger.

I took the liberty, a couple of days ago, of increasing the nofiles ulimit for the "bbs" user from the default 1024 to 1536, though lsof only shows 417 "REG" entries.

Digging a little deeper, though, I'm seeing that 360 of those lsof hits are for one particular file in my /usr/local/citadel/network/spoolout directory (the spool file for the trada node, and that file is only 721.6K).

I've restarted the citadel and am watching the number of file handles (per lsof) grow, and the only network spool file is trada. Wondering if it's an issue with this particular spoolfile, I'm renaming the file and waiting to see if this crops up again.

If you telnet to port 25 on your server do you get an SMTP prompt that says "citadel" in the greeting?

If not, you have some other mail server running on your system and you need to shut it down.

you should see lots of NW lines there then.

[Reply] [ReplyQuoted] [Headers] [Print]

I had a spam attack this morning. I cleaned up the account responsible, but now I am stuck with over 80 thousand messages in my citadel SMTP queue. This queue is so large that I can't use WebCit to clear the queue, because it just crashes trying to load all the messages to get them all selected and deleted. Surely there must be some command line way to clear this queue that doesn't require 6 different JavaScript libraries? The instructions given in the citadel documentation only mention WebCit, and I can't get that to work at all due to the size of the queue.

Unfortunately, this came too late to help with my situation, as I needed to restore mail absolutely ASAP. So I found another answer involving setting expiration and running purges and corrupting the citadel database: http://serverfault.com/questions/596827/how-do-i-clear-smtp-outgoing-queue-in-citadel-server-via-command-line/596853#596853 but at least it'll be there for the next poor sap who's stuck in this awful situation. Unfortunately, this has shown me that citadel does not offer complete enough administrative functionality for my purposes. When things go wrong, the custom format on disc and custom text client make them impossible for me, the lowly admin, to fix again in a reasonable (IE 1 to 3 hours) time frame. Thankfully, citadel was still in testing, so the few beta users can be migrated back to Google apps without much trouble. But I'll keep an eye on citadel development in hopes administrators get more powerful tools in future updates. So keep up the good work!

Judging by doing similar things on  other mail systems, one would need to be to do that by Subject or by From or To lines...

Afaik, there is none at the moment. I can try and find out if homebrew or gentoo-prefix will lead to a fast result. Maybe, in the long run, I could try to get a native (intel only) package going. If it does not require more skills than I have at hand. ;)

no, it doesn't have adaptors for these.

you could however probably easily plug them into the spooling mechanism...
