[gentoo-user] [slightly OT] Automounting Windows shares with autofs

[gentoo-user] [slightly OT] Automounting Windows shares with autofs

[Alexander Skwar]

Good $time :)

I'm trying to setup my system so, that it can automount Windows shares.
I'd like to have it so, that I do NOT have to specify each and every
host and share in the automount configuration; I'd like to have it so,
that it's as "comfortable" as the NFS solution that you can get, if you
use /etc/autofs/auto.net. That's a (Gentoo supplied) executable script.
If invoked with the target hostname, it'll print all the available exports
on that NFS host and thus allows to use these exports. Eg.:

askwar@winnb000488 /dev/shm $ /etc/autofs/auto.net winds06
-fstype=nfs,hard,intr,nodev,nosuid,nonstrict,tcp,rsize=32768,wsize=32768,timeo=11,retrans=4,posix,nocto \
        /opt/ORCLfmap winds06:/opt/ORCLfmap \
        /pool winds06:/pool \
        /pool/netbackup-catalog winds06:/pool/netbackup-catalog

So, on that winds06 host, there are 3 exports (ORCLfmap, pool and 
netbackup-catalog). When I now do a "ls /net/winds06/pool", I'd
see what's in the pool export on winds06. In /etc/autofs/auto.master, I've
got:

/net    /etc/autofs/auto.net

I'd like to get something like this for Samba hosts as well. As a
(dysfunctional :() start, I've hacked up a "auto.smb" script, which
you can find at <http://askwar.pastebin.ca/527240>. If invoked on the
command line, it returns:

askwar@winnb000488 /dev/shm $ /etc/autofs/auto.smb winfs001 
-fstype=smbfs,credentials=/home/askwar/winfs001.cred \
         R$      ://winfs001/R$ \
         HOME    ://winfs001/HOME \
         C$      ://winfs001/C$ \
         DAITMeeting     ://winfs001/DAITMeeting \
         DEPT    ://winfs001/DEPT \
         APPL    ://winfs001/APPL \
         F$      ://winfs001/F$ \
         ADMIN$          ://winfs001/ADMIN$ \
         WORKGROUPS      ://winfs001/WORKGROUPS \
         D$      ://winfs001/D$ \
         PUBLIC          ://winfs001/PUBLIC \
         E$      ://winfs001/E$

Those are all the shares on the winfs001 host. In auto.master, I've got
the following:

/smb    /etc/autofs/auto.smb

But it does not work :( When I do a "ls /smb/winfs001/DEPT", I get:

ls: cannot access /smb/winfs001/DEPT: No such file or directory

And in syslog:

Jun  1 09:13:46 winnb000488 automount[15874]: failed to mount /smb/winfs001

So, there's obviously something wrong - but what?

Automounting Windows shares does work with this in auto.master:

/winfs001       file:/etc/autofs/auto.winfs001

And auto.winfs001 being:

*               -fstype=smbfs,credentials=/home/askwar/winfs001.cred,uid=askwar,gid=users,rw    ://winfs001/&

But I don't want to have a line for every Windows host in my auto.master...

What do you guys do? I'm also NOT looking for a Gnome or even KDE only
solution. So anything using kioslaves is out of the question. It needs
to work normally on the command line as well.

Thanks a lot,
Alexander Skwar

PS: I know about <http://gentoo-wiki.com/HOWTO_Auto_mount_filesystems_(AUTOFS)>.
It's not what I'm looking for ;)

Hmm, I guess the output of your script is wrong. Put this line into the awk 
part instead:

{ if (first) { print opts; first=0 }; print " \\\n\t/"$1"\t://"host"/"$1 }

Nice Script, thanks :-) Only drawback of the script approach is that it 
makes automount's "-ghost" option useless.

Bye...

However, xxx$ shares don't work for me, which they do when entered in a 
static auto.windows.

Thx. This works. The difference is, that you're printing "/DEPT", while
I was printing just "DEPT" - IOW: you added a / before the Sharename.
Strange that this is required, though, because in a static map, the
/ isn't required.

Oh, well. As long as it works ;)

Yep. If you have a close look at the syslog, you'll find:

        D       ://winfs001/D

So, for some reason, it's loosing the $. Maybe add quotes? Or escape?
Let's see...

Yep. Escaping seems to be in order.

See http://askwar.pastebin.ca/527548 for the new version of the script.

Yep. I'm not allowed access to D$. This can very well be.

You mentioned auto.net in your first mail. This one also prints a 
leading "/".

I see a different picture :-(. It seems to be the sheer mass of shares on 
that server. From the syslog, it looks like the automounter tries to mount 
every share until it runs out of memory.

That would explain why my static (direct) map works, while the dynamic one 
doesn't.
