rcl.local

stuaz · 03-19-2009, 08:12 AM

Hello,

I am attempting to use rc.local to run a command to mount a drive using the following command:

/bin/mount -t cifs //<IP ADDRESS>/<DIRECTORY> --verbose -o user=USER,pass=PASS,dom=DOMAIN /mnt/ntserver

When I place it in the rc.local file and execute the rc.local file it works with no issues and mounts the drive fine. However If I save the output to a file and reboot the server I get the following error message, and it doesn't mount:

Log of /bin/mount -t cifs //<IP ADDRESS>/<DIRECTORY> --verbose -o user=USER,pa
ss=PASSWORD,dom=DOM /mnt/ntserver
Thu Mar 19 12:48:02 2009

parsing options: rw,user=USER,pass=PASSWORD,dom=DOM

mount.cifs kernel mount options unc=//<IP ADDRESS>\<DIRECTORY>,ip=<IP ADDRESS>,v
er=1,rw,user=USER,pass=PASSWORD,dom=DOM
mount error 113 = No route to host
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
/bin/mount died with exit status 255

The route to host message is normally displayed when no network card is present or functioning - but I thought rc.local was the last thing to run?

Have you tried mounting it using /etc/fstab? You can use a credentials file to hide the username and password from prying eyes (by keeping it in /root, for example):

Code:

//<IP ADDRESS>/<DIRECTORY>   /mnt/ntserver       smbfs   credentials=/root/smb.pass  0   0

Code:

$ cat /root/smb.pass
username=USER
password=PASSWORD

Hi Thanks for your response.

I did try that, but the problem I have is the options codes I use. How are they put in the fstab?

The username and password are stored in the credentials file (/root/smb.pass in my example). Any other options are before or after the credentials option:

Code:

//<IP ADDRESS>/<DIRECTORY>   /mnt/ntserver       smbfs   credentials=/root/smb.pass,domain=DOMAIN,rw  0   0

The layout of fstab is:

Code:

blockdevice mountpoint filesystemtype mountoptions filesystemdump fsckcheck

In essence, the 5th and 6th ones you don't need to worry about and can leave as 0 and 0 respectively. Take a look at man mount.cifs on the specific options you can include and their syntax. Also see man 5 fstab for the syntax of /etc/fstab.

Also, I just realised why your first attempt may have failed; the correct syntax for specifying the domain is domain=DOMAIN, NOT dom=DOMAIN.

Thanks again for the help, but it still doesn't work:

Contents of fstab

Code:

//<IP ADDRESS>/<DIRECTORY>       /mnt/ntserver   smbfs   credentials=/root/smb.pass,domain=DOMAIN,rw 0       0

Code:

# ls -l /root/smb.pass
-rw-rw-rw- 1 root root 34 Mar 19 20:43 /root/smb.pass
# cat /root/smb.pass
username=USERNAME
password=PASSWORD

Are there any new error messages in /var/log/messages about it trying to mount during boot? What if you type mount -a as root? Any errors there? Are you sure you need the domain switch (with mine, I found it worked without it whereas it didn't with...)?

Also, do a chmod go-rw /root/smb.pass so that only root can see the username and password you're using to connect to the samba share.

/var/messages doesn't report any error messages that I can see.

Code:

# mount -a
mount: unknown filesystem type 'smbfs'

I took domain out as well, and that didn't work.

So it's not working because it doesn't recognise smbfs as a valid filesystem, yet you can successfully mount it from the command line? Try changing smbfs to cifs as they're synonymous.

Nope no difference.

pwc101 · 03-20-2009, 05:13 AM

Can you at least still mount it using the credentials file from the command line, as per your original post?

Code:

mount -t cifs //<IP ADDRESS>/<DIRECTORY> -o credentials=/root/smb.pass,domain=DOMAIN /mnt/ntserver

stuaz · 03-20-2009, 06:23 AM

Yep that works perfectly when run manually.

pwc101 · 03-20-2009, 06:45 AM

Don't know then. Sorry.
