What is auto.net supposed to do?

I have got a desktop which is dual boot Windows/Ubuntu and laptop, which
is run on Ubuntu only. I am trying to set up autofs to automatically mount
the shares from desktop on laptop regardless how desktop is booted.

I thought that auto.net script should look up available shares and mount
them in /net. However, it does not happen. In my auto.master I've got the
following:

/net /etc/auto.net --timeout=60

auto.net file contains some sort of script... Any help?

That auto.net script is only for NFS shares, and will not work for
Windows and, or Samba shares; based on this auto.net you may try my
auto.smb sript works for me:

------------8<------------
#!/bin/sh

# $Id: auto.net,v 1.5 2003/09/29 08:22:35 raven Exp $

# Look at what an host is sharing to determine what we can mount. This is

# FIXME: Override a bug/feature in autofs; it's working for only me, but is
# genric enough to be usable by others
[ -z "$HOME" ] || HOME="/home/bsd"

# Get username from $HOME/.sambarc

# Add/edit other applicable smbfs/mount options here.
# Note: "nonstrict" is now set by default, remove it if you don't want it.
opts="-fstype=smbfs,credentials=$HOME/.sambarc,uid=$usr,gid=$usr,fmask=0664,dmask=0775,n onstrict"

# List samba/windows/lan manager shares available on target host (key).
LISTMOUNTS="/usr/bin/smbclient -A $HOME/.sambarc -L $key"

$LISTMOUNTS 2>/dev/null | LC_ALL=C sort +0 | \
awk -v key="$key" -v opts="$opts" -- '
BEGIN { ORS=""; first=1 }
{ if (first) { print opts; first=0 };
if ($2 == "Disk") {print " \\\n " "/mnt/" $1, "//" key "/" $1}}
END { if (!first) print "\n"; else exit 1 }
' | grep -v '\$'
------------8<------------

Create an /etc/auto.smb on your Ubuntu desktop and add the following
line to yout /etc/auto.master

/smb /etc/auto.smb --timeout=20 # or whatever

You will also need to create $HOME/.smabarc files on your Ubuntu
notebook containg the follows lines.

# .sambarc
username=UserNameOnYourUbuntuDesktop
password=SecretForAboveUser

Restart autofs service on your Ubuntu Notebook

invoke-rc.d autofs restart

and type in:

cd /smb/HostnameOfYourDesktop

Hope that helps!

Thanks a lot. I will try to set up auto.smb then.

However, the thing is that auto.net does not mount my NFS shares.

I have edited /etc/exports:

/home 10.0.0.3(rw)

and /etc/hosts.allow:

portmap mountd nfsd statd lockd : 10.0.0.13 10.0.0.11 10.0.0.3
portmap : 10.0.0.13 10.0.0.3

and I can manually mount the shares, but I hoped that they will be mounted
automatically when available.

You're welcome!

Hmmm, may be that the script auto.net installed on your notebook is
buggy. Please post the output of following:

/etc/auto.net HostNameOfYourDesktop

The above settings look fine, and your auto.net should definitely work as
you already have tested these by manually mounting your NFS shares
and, or exported sub-directories from your desktop.

BTW, you have not mentioned versions of your Ubuntu and autofs; these
versions numbers could be quite handy while answering and, or resolving
problems.

-fstype=nfs,hard,intr,nodev,nosuid,nonstrict,rsize= 8192,wsize=8192,async \
/home 10.0.0.11:/home \

Thanks a lot for trying to help me...
