Hello!
Still struggling with setting this up. Is there maybe some fix around it
or some other setting I can use?
One idea, though not for production, is to add just one IP to the config
and then add another Director with "doveadm director add ip", but this
is just for development and testing.
As far as I understand, the Director tries all IPs in the setting and
the first it can bind, it gives it as local IP - self IP. This normally
works, because default setting for net.ipv4.ip_nonlocal_bind is set to
0. So there is probably some other way to check local IP and set it as self?
This "bug" is here for some years now, does anybody have any idea how
would it be possible to fix this?
Thank you very much for your help,
Thomas

Hello everybody!
I kindly ask somebody to help me with this problem. I'm trying to
configure Dovecot proxy with Director. On the same machine is
KeepAlived that needs this configured to bind non local IP:
sysctl net.ipv4.ip_nonlocal_bind=1
But as already mentioned in this email:
http://www.dovecot.org/list/dovecot/2012-November/087033.html
Dovecot Director needs sysctl net.ipv4.ip_nonlocal_bind=0 (if this is
set, everything works ok, but we break keepalived) because otherwise
the second server uses IP from the first server as "self".
Is it possible to configure this some other way, so Dovecot Director
doesn't try to bind to all IPs and because of above configuration,
uses the first one that binds.
This is the result from director status on server 1:
root@u1:~# doveadm director ring status
director ip port type last failed status
172.16.100.191 9090 self never handshaking
172.16.100.192 9090 never handshaking
and server 2:
root@u2:/var/log# doveadm director ring status
director ip port type last failed status
172.16.100.191 9090 self never handshaking
172.16.100.192 9090 never
