Sorry, I don't use KDE so none of that means anything to me. What are the command-line outputs from:

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.

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.

...

In poblano, the client configuration points to the chipotle server, /home, /nfs/chipotle/home mounting point, nfs type, with options rw,nosuid,rsize=8192,wsize=8192. NFSv4 is disabled. Same for the other machine, except that the mounting point is /nfs/poblano/home.

On both machines, /etc/exports contains only a single line: "/home 192.168.1.0/24(rw,root_squash,sync,subtree_check,nohide)".

Check the manpage about the subtree_check option, you probably don't want it. Why have you enabled nohide?

Cheers, Dave

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.

I believe the servers are working properly.

On both machines, the firewall is open for NFS, NFS-Client, and NFS-Server-Service. Both start at boot time.

In poblano, the client configuration points to the chipotle server, /home, /nfs/chipotle/home mounting point, nfs type, with options rw,nosuid,rsize=8192,wsize=8192. NFSv4 is disabled. Same for the other machine, except that the mounting point is /nfs/poblano/home.

On both machines, /etc/exports contains only a single line: "/home 192.168.1.0/24(rw,root_squash,sync,subtree_check,nohide)".

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 works in KDE3, KDE4 even when I use one of each. -- Robert Smits Email bob@rsmits.ca -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

BINGO!

Reading your note, I saw that I had already attended to all the points you mention, except this one -- as obvious as it is, it hadn't occured to me. Reserving addresses in the router has made NFS work as it should. Many thanks.

[snip] And in case it is absolutely necessary to use dhcp, assigning a second, static IP to an interface will also work. This can be set up with YAST, I expect. 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.)
