unable to automount windows C$

unable to automount windows C$

[Scott Belnap]

[-- Attachment #1.1: Type: text/plain, Size: 4841 bytes --]

I'm trying to automount a windows machine.  I am able to automount any
directory that doesn't have a $ in the mount name.  Looks like the
parse_mount method is stripping out the $ from the mount name.  Any ideas on
how to fix this?

I think you might need to escape the $ that gets clobbered. It is most
likely getting interpreted as a dollar macro expansion.

Re: unable to automount windows C$

[Matthew Jurgens]

[-- Attachment #1.1: Type: text/plain, Size: 6009 bytes --]

I've had this same problem from time to time and since upgrading to 
Fedora 10 it has come back:
Fedora 10 - kernel 2.6.27.21-170.2.56.fc10.i686.PAE
autofs-5.0.3-41.i386

The correctly mounted manual entry:
//xp0/C$ on /mnt type cifs (rw,mand)

The autofs entry:
//xp0/C/$ on /smb/xp0/C$ type cifs (rw,mand)

If you need anymore debug info let me know

I have no idea what you are trying to say.
The above, //xp0/C/$, doesn't correspond to what autofs-5.0.3-41 passes
to mount(8) and I have no idea what has happened since you haven't
provided any log information.

Sorry, here is more information:

Windows machine called xp0.

The output of a mount command is:
//xp0/C/$ on /smb/xp0/C$ type cifs (rw,mand)

The incorrect target of //xp0/C/$ does not appear to be reflected in the 
debug output

The correct output of the mount command should be:
//xp0/C$ on /smb/xp0/C$ type cifs (rw,mand)

Clearly it isn't an autofs problem.
It's a mount.cifs (or mount(8)) problem.

Ohh, I get it, the "\" is a path separator for mount.cifs and I think
the handling of it may have changed recently ish.

So catch 22, autofs must escaped the "$" to prevent it being interpreted
as a macro and the generic mount module has no special knowledge of cifs
so it can't do anything about it. Worse, since "\" is a valid path
separator for UNC paths we can't just check the fs type and translate
them all. For example, what if we get :\\\\<server>\\service as the
location?

Yes, when you mount it manually you don't escape the "$".

If I manually mount it using:
mount -t cifs -o username=mjurgens,password=parallel12 //xp0/C$ /mnt/C$
it works. If I also escape the $ then it also works
mount -t cifs -o username=mjurgens,password=parallel12 //xp0/C\$ /mnt/C\$

Was that what you were talking about?

So maybe I'm wrong and were back to were we started.
Unless the shell translates the escape!

I bet that:
mount -t cifs -o username=mjurgens,password=parallel12 \
	'//xp0/C\$' /mnt/C\$
fails.

Maybe.

There is always the possibility of working around things like this.
But it may not be a simple matter to change this as lot of change has
taken place.

Maybe we should try a couple of things and see what we get. I don't have
a Windows environment I can use here so you will have to help.

I'm wondering why I need to double escape the $ after looking at your
debug log.

How about commenting out the line "gsub(/\$$/, "\\$", loc);" in
/etc/auto.smb and see what happens.

Right -- and it's even worse than that. '\' is a valid character in
posix path components. It's perfectly legitimate (though insane) to
have a file named:

/home/jlayton/crazy\file

'crazy\file' is a valid file/dir name.

I did a small writeup on this for the mount.cifs(8) manpage -- see the
section called 'SERVICE FORMATTING AND DELIMITERS'.

I think the only real way to solve this is to make sure that autofs
doesn't try to escape these characters before it calls mount. I don't
think mount does any variable interpolation, and I know mount.cifs
doesn't so there shouldn't be any need for escape chars before '$'
signs, assuming you're not handing these off to a shell of some sort.

Yes, I'm thinking I shouldn't be double escaping the $ as using quotes
around these should prevent the $ being interpreted as a macro introducer.

Good bet.
It certainly does fail. The output of mount for that is now:

//xp0/C/$ on /mnt/C$ type cifs (rw,mand)

Reading ahead in the thread Jeff says "'\' is a valid character in posix 
path components" which does explain this behaviour

Do you really need the \ in front of the $ when it is already quoted?

Reading ahead again I comment out the gsub in /etc/auto.smb which 
changes the output from
-fstype=cifs,username=USER,password=PASS \
         /C "://xp0/C" \
         /ADMIN\$ "://xp0/ADMIN\$" \
         /C\$ "://xp0/C\$"

to

-fstype=cifs,username=USER,password=PASS \
         /C "://xp0/C" \
         /ADMIN$ "://xp0/ADMIN$" \
         /C$ "://xp0/C$"

So the
/C$ "://xp0/C$"
does look at little friendlier but does not actually work (does some 
autofs code need to change as well?).

When I
cd /smb/xp0/C$
I get
cd: no such file or directory: /smb/xp0/C$

I get the same result even trying to
cd /smb/xp0

Of course, it then doesn't escape $ in the offsets.
But, it looks like your script isn't up to date.
I'm fairly sure the current script should output:
 -fstype=cifs,username=USER,password=PASS \
         "/C" "://xp0/C" \
         "/ADMIN$" "://xp0/ADMIN$" \
         "/C$" "://xp0/C$"

which is why I thought we shouldn't need the "\" escapes.
Can you check your auto.smb against the one attached please, in
particular the last line at the bottom of the "/Disk/" block should be:

print " \\\n\t \"/" dir "\"", "\"://" key "/" loc "\""

Because the script file is not executable now it is treating it as a

Not sure how you come to that conclusion since I ran it above to get the

Because of:

Sorry I must be missing something.
You say autofs is now treating the script as a file since it is not 
executable but it is executable.
I don't quite understand the "if (st.st_mode & __S_IEXEC)" part of the 
code above.

All I'm saying is that, for whatever reason, autofs is treating your
program map as a file map. Why I don't know.

The check (st.st_mode & __S_IEXEC) checks if the mode returned by the
stat(2) of the path in ap->argv[0] is executable by the owner of the file.

Can you please then just explain what

"if (st.st_mode & __S_IEXEC)" is testing for?

Ha, but I did!

It is checking if the map (path in ap->argv[0]) has the execute bit set
for the owner.

Yes, it looks OK but I don't know of any problems with this, so I'm at a
loss as to what could be happening.

Does running this script using "/opt/maj/auto.samba <some server>" work?

Sure, but we can't check changes to the script if we can't execute it.

What does the master map entry for this look like?
If you have "file:" in front of the map path that will force autofs to
treat it as a file map.

I found that the auto.master had a file: in front of the /smb entry - 
then I read this (would have saved me some time!)
Now lets stop this part of the thread and I will resume from an earlier

Ian you are brilliant. You know your product very well. Thank you very 
much for your help

I now submit my modified version of the auto.smb script. This auto.smb 
script optionally supports authentication of smb/cifs shares. Only 
tested under Fedora 10. Based on the original script as distributed, the 
work in this thread and my own script.

#!/bin/sh
# This file must be executable to work! chmod 755!
# autofs samba script by Matthew Jurgens June 2009
# based on the original script distributed with autofs
# optionally uses authentication for smb/cifs shares
# mounts shares ending in $ successfully (Thanks to Ian Kent)

# optional authentication information
# either set it here or pass it in via the environment
# SMB_USER=
# SMB_PASSWORD

key="$1" # key comes is as something like a hostname eg matthew

if [ "$SMB_USER" ]; then
   opts="-fstype=cifs,username=$SMB_USER,password=$SMB_PASSWORD"

   # setup up the authentication file for smbmount
   # Sept 2008
   # Going to Fedora 9 smbmount no longer worked properly with the 
username%password syntax
   # Had to implement the auth file using the -A parameter
   smbauthfile=/tmp/smbauth.tmp
   echo "username=$SMB_USER" > $smbauthfile
   echo "password=$SMB_PASSWORD" >> $smbauthfile

   # set up the optional parameter for smbmount for using authentication
   auth_part="-A $smbauthfile"

else
   # set up default options - no authentication
   opts="-fstype=cifs"
fi

for P in /bin /sbin /usr/bin /usr/sbin
do
    if [ -x $P/smbclient ]
    then
        SMBCLIENT=$P/smbclient
        break
    fi
done

[ -x $SMBCLIENT ] || exit 1

$SMBCLIENT $auth_part -gL $key 2>/dev/null| awk -v key="$key" -v

    /Disk/    {
          if (first)
            print opts; first=0

There are a couple of problems with this.

The first thing is that it isn't a patch, it's just a verbatim script.
While this isn't really an issue with this change this is the way it
needs to be done.

Patches should be used to request changes and should apply from the top
of the distribution tree when a "-p1" option is used with the patch
utility and the "-p" option should be used with the diff utility when
making them to give better context.

If you have a Fedora or rpm based distribution the gendiff utility, from
the rpm-build package is quite useful for this, although I seem to
remember needing to add the -p option for the diff to the script.

Also, patches should address one issue, where possible, and have an
accompanying description of what issue or enhancement the patch is
addressing and why you believe it works and any other pertinent information.

For some time now I've been trying to "always" include descriptions with
patches I add to autofs so I think anyone else requesting changes should
do the same.

In this example, I think, there are two distinct changes, the addition
of a couple of variables and the commenting out of the gsub() call.

But moving along ...

I don't think that embedding password information in a distributed
example program map is the right thing to do. People need to work out
how they will access authentication information for themselves and
modify the example program map to suite.

Also, I don't understand how this can be set in the environment. If it
is set in the daemon environment, typically root, and used for every
mount then I don't think that is a good example of usage to distribute
either.

OK, so this is probably the correction I need to apply, but a patch
would remove this line and add a brief description of the reasoning.

This is just how I do it and thought it might help others who are 
perhaps wondering how to do it
I did miss out one line - which is what you are puzzling over.
I include another script which contains SMB_USER and SMB_PASSWORD into 
the environment
I have the line
. /etc/my_user_info
in my version of the script
