[Fedora-directory-users] I have 2 masters in MM mode- how do I add a 3rd and 4th?
Currently, I have 2 FDS in production in Multimaster mode. I want to bring 2 more up as well and put them at a remote site so eventually they will replicate via WAN. Then I will have 2 sets of my data- one at each location. So I plan to bring up 2 new servers in MMR mode with the first 2 servers. Once they are synced up I would then move the new ones to the remote site and use SSH tunnels to re-establish the replication connection. Can someone chime in on the viability of this? Is this possible? What are the steps? I have looked and have not found anything yet. Any help appreciated. Thanks, Dave

I have looked and have not found anything yet.I''d highly recommend against doing it this way. The extra complications added by setting them up and them moving them probably just isn''t worth the effort vs. setting them up the way they''ll be used from the beginning. Unless your LDAP repo is obscenely large, chances are you won''t save much time setting them up locally, either. If I were to go further I''d say you''re asking for trouble trying to keep them synched over SSH tunnels, given the low reliability you''ll have on connectivity. If it were me (and it has been several times) I''d just set up the servers as usual, in the places where they''ll be used, and then use something a bit more reliable (or at least fault-tolerant) as a connectivity method, such as stunnel. Then the only thing you need to do differently is set up replication on the providers to a local IP address, and otherwsie it''s the same as a standard setup.

I once tried to tunnel and LDAP connection over SSH. I needed this because my admin server on public internet was attempting to redirect me to an internal IP address. Technically it should work but I could not make it. One of the issues, that may come up for you, is that the replication agreements are going to be awkward because of tunnel names. localhost:389 etc. I would suggest going the VPN route or just replicating over LDAPS. Same result more logical setup. Edward On 4/30/07, Dave Augustus <davea@support.kcm.org> wrote:> > Currently, I have 2 FDS in production in Multimaster mode.

ok, so is there a way to bring a fresh install of FDS into sync with an existing server?

That''s too easy! This will also make the new one a master as well ?

Set up a replication agreement and initialize the consumer.You''ll need to configure the server as a master, but yes, the sync process is the same.
