[KLUG Members] NFS problems viewing subdirectories

[bfdamkoehler at worldnet.att.net]

As a starting point I would check the logs in /var/log at the time the 
problem occurred.  The log files names can vary from distribution to 
distribution. I would start with /var/log/messages or syslog. I would 
also look in the files in /var/log/daemons and /var/log/kernel. If you 
find any useful logs, do a google search for them..

The file /etc/syslog.conf defines what logging is turned on, and you can 
always turn on more or alter the serverity of the logging.  The lines 
that have a "-" iin front of the filename are disabled.
