I have installed NFS on two machines (called "poblano" and "chipotle"), each with both a server and a client. Both machines run oS v11.1 with KDE3. On poblano, the My Computer disk information list contains the line: "Remote Share (chipotle:/home)". Same on chipotle, with the substitution of the poblano name. On chipotle, when I click on this line to enter the shared directory, Konqueror shows a blank window with "media:/home" in the Location window. A dialog window appears reading "Permissions denied". I do not know what permissions it means. Doing the same on poblano also produces the blank window, but the dialog window is present for only an instant, and disappears. When I close the window Yast > Network Services > NFS Client in poblano, there is an error message: "Unable to mount the NFS entries from /etc/fstab". The NFS line in fstab is"chipotle /home /nfs/chipotle/home nfs rw,nosuid,rsize=8192,wsize=8192 0 0". This does not happen on chipotle, which contains exactly the same line in fstab except of the name substitution. I believe the servers are working properly. Here is the result of running on poblano (running it on chiplotle yields a similar result)". ***** # rpcinfo -p program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100005 1 udp 49986 mountd 100005 1 tcp 51660 mountd 100005 2 udp 49986 mountd 100005 2 tcp 51660 mountd 100005 3 udp 49986 mountd 100005 3 tcp 51660 mountd 100024 1 udp 42007 status 100024 1 tcp 45664 status 100003 2 udp 2049 nfs 100003 3 udp 2049 nfs 100021 1 udp 42904 nlockmgr 100021 3 udp 42904 nlockmgr 100021 4 udp 42904 nlockmgr 100003 2 tcp 2049 nfs 100003 3 tcp 2049 nfs 100021 1 tcp 49781 nlockmgr 100021 3 tcp 49781 nlockmgr 100021 4 tcp 49781 nlockmgr ***** I interpret this as meaning that the servers are in order.

That line is in error. You need to have the correct format - man 5 nfs - the example shows the format: server:/usr/local/pub /pub nfs rsize=32768,wsize=32768,timeo=14,intr Note the colon. Read the manpage for options, yours are probably fine.

Then restart the servers, then remount the filesystems on the client. On both machines, using the command line, and report all output on the command-line and in the logs.

Stan, I have reasonably good results now with using nfs on a gaggle of boxes at home. On each machine I want to be able to export files from, I go to Yast and ensure the Yast2 -NFS Server is installed. I think it will also install the nfs-kernel-server. I make sure the server machine has a fixed IP address so it won't change every time it logs on. Then I go to Konqueror, right click on the folder I want to export, click on properties, then share. Click on configure file sharing, give the root password, then configure the file to share. When you close the config box, there will now be an icon on top of the folder indicating it is shared. The other way of doing this is to go to Yast, click on network services, nfs- server, and then configure which files you wish to export. Don't forget to set them to rw instead of the default ro if you want to be able to write to nfs files. On the client box, I go to YAST, network services, nfs-client and give it the IP address of the server. Then I can select which files to import and where to put them. This works quite well, and I NEVER fuss with the fstab files manually. Ever.

It can also be done manually with ifconfig and it's successors for testing, etc. (A lot of people [still] don't know that an interface can have more than one IP address.)
