Mounting Linux drive on Linux: error 21874

Mounting Linux drive on Linux: error 21874

[Eve Atley]

Hi folks,

I'm attempting to mount a Linux drive via Samba from a Linux box like so:

mount -t smbfs -o
username=someusername,password=somepassword,workgroup=workgroup
//localhost/dev/hda3 /mnt/devbox

This error results:
21874: session setup failed: ERRSRV - ERRbadpw (Bad password - name/password
pair in a Tree Connect or Session Setup are invalid.)

Directory's been created (devbox) under /mnt/ directory. DF on the box I'm
attempting to mount shows:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda3             30233928  12852120  15845996  45% /
/dev/hda1               101089      9193     86677  10% /boot
/dev/hda2             42330704   3414040  36766364   9% /opt
none                    514528         0    514528   0% /dev/shm

I know the username and password is correct, but the name of the box may not
be (shows 'localhost' at prompt when logged in). 

What am I doing incorrectly?

Thanks,
Eve

It is hard to say for sure ... but I too am suspicious of "localhost". It 
is probably just a bad config of the SMB server host (a bad entry in 
/etc/hostname). But the client you are trying to mount from sees 
"localhost" as itself (a standard convention, which you'll almost surely 
see as an entry in /etc/hosts that resolves localhost to 127.0.0.1, the 
machine's own "lo" interface).

Try replacing "localhost" in the mount argument with the actual IP address 
of the SMB server host or with something that the *client* host can resolve 
to that IP address (exactly what depends on how you've set up your on-LAN 
DNS or the contents of the client's /etc/hosts file ... whatever its 
resolver uses for LAN hosts).

If that is not it ... how do you "know" the password is correct? Samba 
passwords are not necessarily the same as shell login passwords ... whether 
they are the same or different is site-specific, so ask the server's 
sysadmin how this server is set up (unless that's you, of course, in which 
case you already know about this part).

RE: Mounting Linux drive on Linux: error 21874

[Eve Atley]

Hello again and thanks,

Trying this one:
mount -t smbfs -o
username=someusername,password=somepassword,workgroup=workgroup
//192.168.10.28/dev/hda3 /mnt/devbox
(perhaps this is incorrect syntax?)

And getting this:
Error connecting to 192.168.10.28 (No route to host)
23617: Connection to 192.168.10.28 failed
SMB connection failed

There *should* be a route to host, since I can SSH into the box. :) 'uname
-a' does indeed show the hostname as 'localhost'. The /etc/hosts file shows
the standard 127.0.0.1 localhost entry. And as the 'unofficial' sysadmin,
I'm sure of the system's username/password. So, I'm going out on a limb here
and guessing that maybe I should change the hostname so that uname reports
something other than localhost. 

If that's a good guess, what's the best way to go about it?

My only other guess is that Samba is not configured on 192.168.10.28...

Thanks,
Eve

I'm not really up to date on this, but I fiddled around here and got these 
to almost work (password deleted here, of course):

kuryakin:/home/autovcr# mount -t smbfs -o username=ray,password=********
//waverly/shared_video /mnt

kuryakin:/home/autovcr# mount -t smbfs -o username=ray,password=******** 
//192.168.1.1/shared_video /mnt

The "almost" is because the kernel on kuryakin isn't set up to support 
smbfs filesystems ... but both smbmount and the SMB server on waverly seem 
to like this syntax). And it does seem to indicate that this syntax will 
take an IP address, which was what I actually wanted to confirm.

So, compared to mine ... the workgroup= piece seems unneeded, and you need 
to specify the name of the share the way it appears in your smb.conf file, 
not the /dev entry for the filesystem ... but the next thing you write 
suggests you have a different problem.

Nothing to do here but check the routing table, right? netstat -nr is one way.

This is most likely irrelevant to your problem ... but this hostname is 
just the contents of the file /etc/hostname . Whether you want to edit that 
directly or change some script that writes a value here is distro specific, 
sometimes even installation specific. Try editing the file by hand and see 
if the change survives a reboot; if it doesn't, hunt for the init script 
that writes to this file.

Even the "'unofficial' sysadmin" shouldn't have to guess about that. Tsk tsk.

In the output of "ps ax" on the server (192.168.10.28), you want to see 
something like --

         16498 ?        Ss     2:29 /usr/sbin/nmbd -D
         16500 ?        Ss     0:00 /usr/sbin/smbd -D
         16501 ?        S      0:00 /usr/sbin/smbd -D

And you want a config files that specifies the share; I'm not sure how 
standard to config-file location is, but my Debian systems default to 
putting it in /etc/samba/smb.conf . You want in it stanzas that look 
something like this (this is an on-LAN public share, so a bit different 
from what you want):

         [shared_files]
         writable = yes
         locking = no
         path = /home/shared_files
         public = yes

(This example is for a share that Windows systems connect to here all the 
time. I never bothered to set up Linux access via SMB, since I still use 
NFS for that.)

There is a lot more detail to setting up the SMB service than I've covered 
here. If you get closer and have specific questions, please don'thesitate 
to post again ... but right now, I don't know what specific problems you 
might have aside from what your message identified, so I'll defer anything 
more.
