mountd and/or pcnfsd problem

Ross Goldman_2 — Fri, 09 Jan 2004 08:09:45 GMT

I have an old DOS application that mounts an exported file system using FTP software's PCTCP idmnt command. This configuration works fine when the host is at 10.20, but fails on my 11.0 host. Near as I can tell both host setups are the same. The PC error is "Mount access denied" and the mountd log reports "mount request from (anon) denied: Permission denied" The PC is coming in as user "nobody" There is no pcnfsd.conf config file.

I'm running out of time so upgrading the DOS app really isn't an option. Any help would be greatly appreciated!

Check the file /etc/exports, the output of showmount -e (should be more or less the same), etc. Probably the problem is somewhere in those config files.

Also check if the HP-UX 11 system can resolv the IP address of the PC...

The exports appear to be OK. The 11.0 host can ping the PC. From the PC I can telnet and ftp into the 11.0 host. The file system I'm trying to mount has full access permissions. Could this problem be some difference between 10.20 and 11.0?

It could very well be a difference between 10.20 and 11.00, but I think it is more related to the different moments in time of configuring the HP-UX machines or perhaps the different IP addresses or something like that.

I think you could help us help you by posting the showmount -e outputs of both the 10.20 and 11.00 box for the filesystems you are trying to mount on the PC (the one that succeeds and the one that fails).

Also, check for the presence of the user nobody in the password files on both UX boxes. Perhaps there is a difference between those that's causing the problem.

Hope you can solve this before I'm online again (probably not before monday).

The "nobody" user is the same in both passwd files.

showmount -e on 10.20 (works):
/export/ford/ut040018 all_ut
/export/ford/ut040018/unix all_ut,
136.17.176.123,
[bunch of IP addrs],136.17.180.151

showmount -e on 11.0 (does not work):
/export/ford/utprod all_ut
/export/ford/utprod/u all_ut,136.17.180.151

136.17.180.151 is the PC in question
