[opensuse] Setting up NFS with Suse 10.2
Hello I'm looking to set up Suse 10.2 to share files between several computers in my home via a wireless router. [Linksys WRT54GL] The router is the connection to the internet btw. I would like to use NFS but having never done so before I'm looking for some advice and/or links to how-to files for SUSE. Currently I have installed the NFS software for client and server on the main machine and my laptop and have tried to get them to talk to each other with no luck. All my attempts at configuration have been done with the YAST2 modules since I figure that is the most fool-proof method. Q: Do I need to have NIS server setup? The machines get their addresses from the router's DHCP. Is this relevant? Q: Is there a special configuration I need to do within the router? VPN? Q; Is there a better way? Samba, iFolder? Thanks in advance, Tim -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi, You don't need a NIS setup. You don't need anything special in your router. I think the best way is to manually edit /etc/exports and /etc/fstab and then use YaST to start the NFS server service. This is your server.../etc/exports /home/somedir/ashareddirectory 10.0.0.0/255.255.255.0(rw,sync) #the PATH of the shared stuff the network/mask some options In YaST, select network services, start the NFS server. This is your client..one of many, in /etc/fstab do something like... 10.0.0.30:/home/somedir/ashareddirectory /home/someuser/some-directory nfs rw,rsize=8192,wsize=8192 (all of the above in one line) Does this help? -- ------------------------------------------------------------------------- Med venlig hilsen/Best regards Verner Kjærsgaard SuSE10.2 2.6.18.2-34-default 8:36pm oppe 2:09, 4 users, belastningennemsnit: 0,09, 0,18, 0,24 ------------------------------------------------------------------------- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

NFS is pretty insecure. Might as well just disable the firewall and invite the internet to the Open House on your system.

I think you're confusing the issue. People are talking about the SUSE firewall on the NFS server box. According to the OP, this is all internal to his network. The 'real' firewall to the Internet is a wireless router. OTOH, you could offer an alternative solution to NFS.

Right, you have to open
- - portmap (111)
- - nfs (2049)
- - some port where you want to run mountd on [1]
[1] you must also configure mountd (on the NFS server) to always use the
same port -- that can be achieved by setting
MOUNTD_PORT="2222"
(or whatever port) in /etc/sysconfig/nfs
(and rcnfsserver restart after changing that file)
On the client side, tell the NFS mount to use that port, by setting the
"mountport=...." option in /etc/fstab, e.g.
nfsserver:/some/export/dir /some/local/mountpoint nfs \
tcp,mountport=2222,rsize=8192,wsize=8192,retry=10,bg,soft 0 0

Tim, Don't know anything about 10.2 but I doubt it's changed much. NFS is very stable. Verner is right. NFS is easy if you RTFM first. man nfs, man exports. Once you have the /etc/exports file set up on the server, the basic command on the server is 'exportfs -a'. Once you have the /etc/fstab file set up on the client the basic command is 'mount -a'. The firewall is the gotcha. For that reason, I might use YaST to set up the server (or just turn the firewall off as verner suggests). But if you do use YaST, go and check /etc/exports and /etc/fstab by hand. Make sure that you understand what each option is for and that it's what you want (hint: the default that YaST sets in /etc/exports isn't what I'd want) HTH, Dave PS Don't use NIS! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

===================================================== In the absence of a NIS server, the UID and password of the current user on the NFS client must match a UID and password on the NFS server. (The purpose of NIS is to centralize authentication, to avoid the labor of manually matching UID's and passwords across systems.) (It saves me a lot of work, even on my small network, but may not be worth the setup effort for your needs) In the context of your LAN, the router only acts as a switch (ok, it's also a DHCP server), it's routing/firewall functions are not relevant. I would suggest using a static IP for the NFS server, and putting an entry in /etc/hosts on the client(s). NFS is the native file sharing protocol of *nix, just as Samba is based on the native file sharing protocol of Windows; IMHO using the native method of the OS will yield the best results, only use a non-native method when cross-platfrom compatibility is needed. Try a Google search for NFS howto; TLDP does a great job of explaning how to set this up. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Thought I'd update the situation, I've gotten Samba to work between machines so thats a start. I'm still fussing about with the NFS setup but haven't tried all the suggestions made here yet. I'll let you know when that works out. Thanks for all the help, it is appreciated.
