Help with NFS and automount

Help with NFS and automount

[Jeffrey S. Mulliken]

Dear Brainiacs,  

    I am having a problem and have come to the end of what I can think 
of to try.   Scenario:

    CLIENT MACHINE:
    RH 7.2  Base
    2.413-ac8 Kernel
    autofs 4.0.0
    mount 2.11g
    pptp-linux v 1.0.3-1
    Linksys BESFR41 4 port router

    HOST MACHINES:
    Gateway = RH 6.2 running firewall and VPN over PPTP
    RH 6.2 machine serving NIS (yp) and DNS
    SUN Ultras w/Solaris 2.51 and 2.6 serving NFS shares.

    PROBLEM:
    Client machine IPL's without any problems.  All of the machines in 
the host network are accessible via ftp or telnet.  
    Several nfs mounts are mounted via the /etc/fstab, and mount without 
problems, and are useable
    A particular nfs mount point gets mounted by the automounter 
successfully via a file /etc/auto.ccwork.  No problems there.
    However, trying to access the same machine as above using the 
program /etc/auto.net, results in "No such file or directory".  
    No errors in /var/log/messages, nor in /var/adm/messages on the 
Solaris host.  I will attach the pertinent files.  
   
    Any suggestions with be greatly appreciated.

Does /etc/auto.net have the executable bit set?
Does typing /etc/auto.net <hostname> return anything?, eg.

-fstype=nfs,hard,intr,nodev,nosuid,rsize=8192,wsize=8192 \
	/local marge:/local

Simon,

    Thanks for the reply.  Yes, /etc/auto.net is executable, and if I 
run the auto.net program as
you suggest it returns the following:

==============================================
[hostname: ] /etc/auto.net dev3
-fstype=nfs,hard,intr,nodev,nosuid \
        /ccStore16 dev3:/ccStore16 \
        /ccStore19 dev3:/ccStore19 \
        /ccStore20 dev3:/ccStore20 \
        /ccStore21 dev3:/ccStore21 \
        /ccStore22 dev3:/ccStore22 \
        /export/home dev3:/export/home
==============================================

But, for some reason, when I try to mount it, I get:

=====================================
[hostnames]# cd /net/dev3
bash: cd: /net/dev3: No such file or directory
=====================================

.....and as I was writing this, I gave it another try, and it's 
resolved. I don't know for sure what
the original problem was, but the machine was originally a RH 6.2 
machine, and I had done
an upgrade to 7.2.  Well, I backed up a couple of files, and did a full 
install, starting with
formatting the partitions.  After the cold install, and 
re-configuration, it now works.  Thanks
to all for any and all head scratching along with me.  

    Cheers....  
   
        Jeff.
