BACKGROUND: Hi, I'm in the process of trying to teach myself Ubuntu (particularly in the server space). I've been a long time Windows guy, but felt it was time to widen my experience. I've been fideling with various aspects of Ubuntu Server (and desktop) and really like it. But I've just ventured into trying to run multiple servers and that's where I think I'm missing something. This is my first Ubuntu Forum post, so feel free to point out the obvious thing I've missed, I wont be offended.
ENVIRONMENT: My current main issue is NFS sharing. I have a server running Virtual Box (I run Windows Guests too). Essentially I'm trying everything on Virtual hosts before I apply anything to the physical host. I'm running it all on a i7 desktop (or two) with 16GB RAM and a Raid 5 MDADM array.
ISSUE 1: I was trying to work out how to setup NFS server and mount's but I can't see the exports from the client, it just times out. I can however see the exports I setup on the physical host. I can't for the life of me work out what's missing on the virtual server compared to the physical server. I can ping the server from the client, but "shomount -e [server]" or rpcinfo -p [server] just timeout after 60 seconds or so.
ISSUE 2: I also dont get how file permissions in an NFS mounted directory will work.
(Currently I have not hooked up Kerberos, or OpenLDAP to NFS, as my NFS shares will really only be exported to other servers, most clients are Windows/Mac and can use the SAMBA system which I will hook up to OpenLDAP).
If Client Server A has a big data directory that an application uses, will it be able to write files to the NFS mounted directory with correct permissions for the local users? When I tried to rsync -av the files onto the NFS mount, I recieved some error's and the file user/group information was lost (sorry, dont remeber the error, I'm at work now).
- So, what could be blocking my NFS exports from VM to VM? (UFW is not active)
- And what should I do about permissions for my NFS exports?
- I started using 11.04, but I've since noticed a few comments around suggesting I should probably stick with 10.04 LTS, not least of which is that LDAP change significantly in 11.04. Should I go back to 10.04, or not worry about it.
- Is it worth using Zentyal to get up and running quickly with LDAP and samba shares, and PDC? It seemed very easy to get Zentyal up and running, but I lost the LDAP attribute "mail" when I had a quick go, however when I have done it manually, I dont get how all the parts fit togeather to provide end to end auth, and are having trouble finding a site that does more than a step by step how to with any decent explanation of the parts (as I'd like to understand it, not just get it working).
Any help and guideance would be appreciated.
