edubuntu-users Digest, Vol 29, Issue 30

Thu Nov 13 01:06:01 GMT 2008

Hi I have a question about multiple server setup. I have setup an LDAP
server and I need to have a server in every classroom. So right now I have 2
servers, that authenticate on the LDAP server and each server has its own
subnet. All thin clients authenticate on the LDAP server as well. Now, the
home directory of every user is an issue. How should I go? I have 2 choices:
1- Attach a Dell MD1000 PoweVault on my most powerfull server (out of the 2
that I have now) and export a huge drive using NFS and mount it on every
server with the same name? or 2- Get a NAS box plug it on the network of the
servers and export with NFS and mount on every server the NAS box share?
Does anyone have any other suggestion? I do not need a failover server, I
just need a server that will have 25 clients max each.

thanks
