[SLE] Question: NFS for beginners
Seems I'm living a life of balance... One problem solved and posted for everyone to benefit from, another question pops up and I need everyone's help. :-) I've got home directories on my files server. I'm running Samba, and all my windows boxes get their home directories assigned to /pchome/%S (ie, /pchome/username) to keep them separate from their linux home directory. I'd like to set it up so that all my linux workstations get their home directories from the file server. I'd like the file server to be the only repository of login authentications (ie, the only holder of /etc/passwd and /etc/shadow). I've got about 6 different user accounts that have (unfortunately), different user id's. Ie, "agtiger" might be user id 500 on one box, and userid "503" on another. I didn't add them in the same order. I know I saw someone else recently post that they did this kind of nfs home directory sharing, and that they wished they'd done it much sooner. Anyone willing to post their NFS configuration files so I can get a jumpstart and don't have to tackle this with "trial-and-error (mostly error)"? ;-) Argentium -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/

I understand there's a way to synchronize UIDs and GIDs automagically, but I didn't need to go that far. this maps UID 1000.100 on the client machine to 500.100 on the server. -- Sturgeon's Law: 90% of everything is crud. -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/

I'm a bit confused. What's new. I bought a second computer and put SuSE6.4 on it yesterday. What I'd really like is a way to make the new computer just like the old one. But I'll settle for just using NSF to copy files over. What I don't clearly understand is 1) is yp (NIS?) required, or is that only for unified login? That is, is NIS required for NFS? 2) if NIS is required, how do I determine who the server is? I'm unclear on how the settings differ for each (client and server) machine. I assume I can set up NIS all in yast.

NSF and NIS(eg. YP) are two separate things. You do not need to configure NIS for NSF. The main thing you need to be concerned with is that your user ids on both your systems are consistent. On 12 Apr 2000, at 8:12, Bill Moseley wrote:

/etc/exports
[ Rest of example snipped for brevity ] Hey, thanks. :-) That gives me a core example to work from when reading the documentation - exactly what I needed. I agree, the static mapping doesn't seem to be too much of a pain in the butt where only a few userid's are concerned. Just for fun, and because I love thinking about future expandibility, what if I had a few thousand userid's to manage; is there a way to match based on the username rather than the userid?

Happy I could help.

As I understand it, yes, but not from personal knowledge. The picture I have is that static mapping works for a few users, running ugidd for a few more, and NIS for many, many users.

I know I saw someone else recently post that they did this kind of nfs home directory sharing, and that they wished they'd done it much sooner.
That was me. Now I wish I hadn't done it at all. I had problems with Staroffice which I managed to work around. I had problems with Wordperfect which I didn't manage to work around. Then the NFS went loopy (it seemed to be the client end rather than the server) which caused the client end machine to slow down to a crawl, eventually leading to a hard reboot. That was enough of that. I backed out what I'd done and will try it again when I have a 2.4 kernel with it's improved NFS support. As someone said, NFS on Linux sucks at the moment. My 24 hour experience seemed to bear this out... -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/

<rest of tale snipped> Thanks for posting the results of your NFS experimentation. I think I'll still proceed, only now I know to proceed with non-critical shares _first_ before jumping in with both feet (probably a wise idea in any event). I wouldn't want to see this happen with a home directory share; that could get ugly _fast_.

Hopefully that won't be too far away, since we're up to 2.3.99 pre 5. :-) -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/

For this you'll probably need to set up NIS/YP. This would be a great time to get stuck into /usr/doc/howto/en/NIS-HOWTO.gz - have fun!!!

I set up a couple of NFS server/clients a couple of weeks ago for the first time. I didn't find it at all complicated, but then again it was a reasonably simple configuration that I was dealing with. All you really need to do is edit the /etc/exports file as appropriate (see 'man exports' for help with this) and then restart the NFS server with the command 'rcnfsserver restart'. All this has to be done as root, of course. This is where Linux gets really fun...
