Description of Problem:I am unable to mount nfs exported file systems from
a Solaris 2.7 machine. Also if I run rpm with the -q option on net-utils I
am told the package is not installed (same if I try to uninstall the
package). If, however I try to install the package using the -ivh option I
am told it is installed. Gnome rpm crashes with a segmentation fault if I
find the package and try to query it or uninstall it. I am running Linux on
a laptop with a pcmcia network card (D-Link DFE650).
How Reproducible:Either run command mount /mnt/home at the command line
(the file system is set as user mountable), use the desktop icon to mount
the file system, or attempt to mount the file system using linuxconf, or
attempt to mount the file system at boot time.
Steps to Reproduce:
1. Always reproducable
Actual Results:If I run mount /mnt/home from the command line, or use the
desktop icon, I get the error mount: RPC: Timed out, using linuxconf I get
the error "* The command takes more than 15 seconds to execute, odd" and
the option to kill the command, and if I try to mount at boot time I get
the error Network unreachable (but I can access the network using nslookup,
ping etc after booting and lpd successfully accesses network printers).
Expected Results:File system mounted and accessable
Additional Information:Extract from netconf.log attached
These are really two separate bugs. You'll probably get better answers in the
future if you file two bug reports.
Now, having said that...

Try passing the -U option to rpm. If that doesn't work, try rebuilding the rpm

This usually means that the server is not responding to mount requests. Either
the server is unreachable from the client, the server doesn't recognize the
client, or the server/client is misconfigured.
Since you can ping the server, I would reject the first option out-of-hand.
Recheck the server's /etc/exports, and make sure all the required services
(statd, mountd, portmapper, etc.) are running on the server. The portmapper and
statd should also be running on the client.
If all this is correct, see if you can telnet into the nfs port on the server.
Do you have another non-linux machine you can use as a test client? If you can
mount from that machine, that would narrow it down to a linux-specific problem.
As a final option, you might try exporting the file system as NFS-version2.
Make sure you are exporting using UDP (which is the Solaris default, I believe)
and not TCP.
