I've had 2x director ring up and running with production load on 2.1.8 with around 10,000 active connections for two weeks and everything has been working great - until this morning. There isn't anything obvious in the logs beyond the fact that the director connections started bouncing. It was not resolved by...

We just had a bunch of backend boxes go down due to a DDoS in our director cluster. When the DDoS died down, our director ring was a mess. Each box had thousands (and hundreds per second, which is a bit much) of log lines like the following: Apr 03 19:59:29 director: Warning: director(10.1.20.10:9090/left): Host 10.1.17.15 is being updated before previous update had fin...

Hi, still using 2.2.9, I've two directors, and these directors use both IPv4/IPv6 addresses. `host directors.<domain>` returns one A and AAA for each of the two directors: directors.<domain> has address 149.x.y.96 (director1) directors.<domain> has address 149.x.y.97 (director2)...

Hello, I'm build system with two director/proxy and dual stack network (or IPv6-only local services) http://wiki2.dovecot.org/Director say "This also means that a single director ring must use either IPv4 or IPv6 addresses, but not both at the same time." OK All servers have 2 interface (public and local network), and all dual s...

I've got a couple more issues with the doveadm director interface: 1) If I use "doveadm director remove" to disable a host with active users, the director seems to lose track of users mapped to that host. I guess I would expect it to tear down any active sessions by killing the login proxies, like I'd done 'doveadm direct add HOSTNAME...

I say "mostly" because the service is working as far as the user is concerned, but I see some strange going on in the logs. Grepping "director" in the log file, I can see that there...

I just noticed this error in my logs: director: Error: doveadm not compatible with this server (mixed old and new binaries?) director: Error: director(10.161.192.28:541/right): Wrong protocol in socket (director-doveadm vs director) The first error I removed by changing director_doveadm_port = 541 to director_doveadm_port = 542 Not real...

But if in the configuration of the director is stated login/director. Than I assume this socket should be in the login dir not? You have also the director activate with executable = imap-login director? -----Original Message----- Subject: Re: Login/director not created On my install the login/ dir is: drwxr-x--- 2 root dovenull...

I haven't heard of anyone having done that though. Just upgraded my Director and got this within minutes.

Hi, I've just setup a testing enviroment for director, and it's not working as expected. I have just 1 director (called director) and 2 dovecot servers (dovecot1 and dovecot2); these are exact copies. First problem: when both dovecot servers are up, every imap connection is redirected to the same server as you can see here: $ sudo doveadm dir...

hi, we are using the dovecot-rc1 version, and we are testing the director service, as there is little documentation on this service, a pair of questions.. if i'm not wrong, the proxy_maybe it's not implemented, yet? will be soon? this limitation does not allow use the same two directors servers like mail backend servers? the fairlure of one director server it&...

Hi Guys, I am trying to use 2 instances of Dovecot on the same server so I can have a Director managing my connections, everything appears to be working, but I can not use doveadm to control my 2nd instance, but doveconf seems to work fine.

As someone who is about to begin the process of moving from maildir to mdbox on NFS (and therefore just about to start the 'director-ization' of everything) for ~6.5m mailboxes, I'm curious if anyone can share any experiences with it. The list is surprisingly quiet about this subject, and articles on google are mainly just about setting director up. I've yet to stumble across an article about someone's experience...
