need help in zimbra replication

[jant0y]

hello guys,

sorry for noobish questions. i'm new to this and confused.
i'm using split dns for my zimbra server here since my server is behind a firewall.
now, my boss wants me to do an ldap replication

do i have to add another zone entry in BIND configuration or should i just add an MX and A record in my current zimbra domain?

thanks for any help,
Jantoy

hi guys,

i got the firs issue resolved. i just needed to add mx and a records

my next problem is when i was installing ldap and snmp in replica server
it won't allow me to continue if hostname and the ldap master are not the same

in common configuration, if hostname is mail2.zimbra.asi.com and my ldap master hostname is mail.zimbra.asi.com, i can't proceed with the installation

if i make them the same i get an error later in the installation


may i know what's wrong with my setup?

[jant0y]

i'm getting this during installation of replica server
i got not "a" option

hope this information helps

anyone got an idea why this is happening?

[jant0y]

ok, i found something odd

i can't locate zimbra.asi.com when i do nslookup from slave server

[root@mail2 ~]# nslookup zimbra.asi.com
Server:         192.36.253.120
Address:        192.36.253.120#53

*** Can't find zimbra.asi.com: No answer

ok i think i found the root problem
my slave server cannot see the master server..

any ideas on how to resolve this?

[jant0y]

found out something new, apparently i placed

192.36.253.201 zimbra2.asi.com zimbra2

in slave server's /etc/hosts
changed it to

192.36.253.201 mail2.zimbra.asi.com mail2

will give an update on how it goes

[jant0y]

even in master server, nslookup zimbra.asi.com still gets nothing

is this because i'm using split dns?

[jant0y]

i reinstalled the master server and slave server.. they're working fine now

do i need to configure the servers to use the replica server? is that needed?
