mounting windows shares from Linux

[Woofage]

When I ran Ubuntu 7.10, this command:

Code: [Select]

sudo mount -t smbfs //<machine IP>/<share name> /<mountpoint> -o credentials=/home/<homedir>/.smbpassword,uid=1000,rwworked perfectly. Since upgrading to 8.04 last week, it doesn't, and I get this error:

Code: [Select]

mount error 20 = Not a directory
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
I've tried mount -t cifs but I get the same error. What's going on? Help!

What happens if you just sudo mount ?

What happens if you just sudo mount ?

pooter says "no" (same error)

Additional info:
I can get to the share using the "smbclient" command, so the "Not a directory" has left me baffled .

Thanks. I'd already tried the "nounix" option after doing some searching, ie:

Code: [Select]

sudo mount -t smbfs //<machine IP>/<share name> /<mountpoint> -o credentials=/home/<homedir>/.smbpassword,uid=1000,rw, nounixSame error, unfortunately.

I would try moving the -o bit to BEFORE the mount points but after the -t part, thus:

sudo mount -t cifs -o credentials=/home/<homedir>/.smbpassword,uid=1000,rw,nounix //<machine IP>/<share name> /<mountpoint>

Oh and remove the space from before the nounix, mount can be funny about the order and whitespaces in the -o options.  I would stick with -t cifs though as smbfs is deprecated (YAY the first time I have needed to use deprecated on a non-tech forum! )

It might also be worth adding the uid and gid to the -o part

Here's the output from my syslog/auth.log:

Code: [Select]

May  7 13:22:16 mob-desktop1 sudo: PAM unable to dlopen(/lib/security/pam_smbpass.so)
May  7 13:22:16 mob-desktop1 sudo: PAM [error: /lib/security/pam_smbpass.so: cannot open shared object file: No such file or directory]
May  7 13:22:16 mob-desktop1 sudo: PAM adding faulty module: /lib/security/pam_smbpass.so

Just remind me how I look that up

[Greenbank]

id -a username

$ id -a alexg
uid=427(alexg) gid=101(dev) groups=101(dev)

[tiermat]

uid can be found in /etc/passwd, gid in /etc/group.

It would appear though, from your logs that you have a missing or corrupt /lib/security/pam_smbpass.so, which should come as part of samba-common.

Try this :
# sudo find / -name pam_smbpass.so

You may find that it is actually somewhere else, the most common problem I have come across is that the pam modules are actually in /lib64/security, but the files in /etc/pam.d have not been properly updated to reflect this.

This looks like it might be your solution:

https://bugs.launchpad.net/ubuntu/+source/pam/+bug/218110

I take it that this is an upgraded box, not a clean install?

Upgraded, yes.

I installed libpam-smbpass but so far no success .

Found the fix, sort of by accident. If I put

Code: [Select]

-o user=<myUserName>,pass=<myPassword> in the command string instead of using the credentials file I get this error:

Code: [Select]

bash: <someCharsInPassword>: event not found
Ah! It doesn't like the password, or something about the password being passed from an external file. It's OK, however, if I do this:

Code: [Select]

-o user=<myUserName>,pass='<myPassword>' or if I leave out the password and type it in the terminal when prompted.

[Greenbank]

Does your password contain any of the following symbols:

- = , $

?

[Woofage]

Does your password contain any of the following symbols:

- = , $

?

!
- which it obviously doesn't like! Which is odd, because it was OK before

[bobajobrob]

mount error 20 = Not a directory

Not the most helpful error message either.

Some non-alphanumeric characters have special meanings on the command lines:-

Try the following:-

echo !2

compared to:

echo '!2'

Then (if you don't mind your password being in your shell history file) try:

echo your_password

If the output is not what you expected then it's because part of it is being expanded by the shell.

[EDIT] Ah yes, just seen you were getting this:-

Code: [Select]

bash: <someCharsInPassword>: event not found

Which explains it.

The shell replaces !X with whatever is entry 'X' in the shell's history. i.e.

$ history | grep 11
   11  ./pamtest.solaris2 -user wibble
$ echo abc!11def
echo abc./pamtest.solaris2 -user wibbledef
abc./pamtest.solaris2 -user wibbledef

If I try something that doesn't exist in the shell's history, I get:-

$ echo !abcd
bash: !abcd: event not found
