Automount on Michael’s Domain

autofs, automount, auto.master and mounting samba shares

Mon, 21 May 2007 00:00:00 +0000

First I added a symbolic link to /etc/init.d/rc5.d/:cd /etc/init.d/rc5.d sudo ln -s ../autofs S21autofsThen I added to the /etc/auto.master the following line:/media/automounts /etc/auto.smbmountsThen I created the file auto.smbmounts with the following content:michael_msbl.helsinki.fi -fstype=smbfs,username=michael,password=## ://paula/michael Then I created the mountpoint:sudo mkdir /media/automounts/michael_msbl.helsinki.fiThen I activated the autofs daemon:sudo /etc/init.d/autofs startNow whenever one tries to access the directory /media/automounts/michael_msbl.helsinki.fi, the autofs daemon will mount the smb share automatically and unmount after a certain period of inactivity.

smb mounts via fstab or automount?

Mon, 21 May 2007 00:00:00 +0000

I have many computers I need to connect to from my Linux box. Network browsing works, but is terribly slow, so I want to create some shortcuts, that I can mount with a single mouseclick what I need from a list. First I thought to modify the fstab and put there entries that would allow me to easily mount smb shares as a normal user. E.g.://paula/michael /media/smbmounts smbfs noauto,user,credentials=/home/jeltsch/.smbpasswd1 0 0This works if I have the entry mounted at system startup (without the “noauto” entry). If the “noauto” entry is present, the smb share is not mounted at system startup, but must explicitely be mounted by the following command:mount /media/smbmountsBecause of the “user” option in the fstab, every regular user should be able to do this. Not so! First I had to enable the “suid” for the smbmnt command (it appeared to be in /usr/bin/smbmnt, but was linked to a link that linked to /usr/lib/samba/classic/smbmnt:chmod +s /usr/lib/samba/classic/smbmntThen I found contradicting information whether the mountpoint (in my case /media/smbmounts) has to owned by the mounting user or not. To be safe it did:chown jeltsch /media/smbmountsStill I got an error which I couldn’t figure out and I decided to use automounts.

Exporting automounted partitions via nfs

Wed, 04 Apr 2007 00:00:00 +0000

We are accessing data from our server via nfs. The nfs exports are automounted on the nfs clients’ computers. It works fine. However there is a partition (a whole drive in fact) on our server that is automounted on demand. We wanted this hard drive to unmount automatically if it is not needed to save energy and reduce noise levels. When I include the mountpoint of this partition in /etc/exports everything seems to work fine, but automounting this export on a client machine fails. It can still be mounted manually though with a regular mount command. As a workaround (in order to have a desktop link in KDE to the data on the server) I did the following: I added an entry to the fstab: server:/automounts/multimedia /media/multimedia nfs rsize=1024,wsize=1024,noauto,user 0 0 Then I created a shell script: !/bin/sh mount /media/multimedia kfmclient openProfile filemanagement /media/multimedia Then I created a new “Link to Application”, that points to that shell script. As a result of clicking this Link, the nfs export is mounted and a new Konqueror window opens with the contents of the mountpoint directory displayed.

NFS shares & automount

Wed, 04 Apr 2007 00:00:00 +0000

On each computer on the network there is an NFS server running, starting at bootup (edit the runlevel to enable that). In Suse Linux, NFS shares can be configured in YAST (NFS server configuration) or directly in /etc/exports file. Don’t configure the remote root to act as local root! Shares should be configured to be accessed only from the local network 192.168.0.0/24 or 192.168.0.0/255.255.255.0. /media/downloads/ 192.168.0.0/255.255.255.0(root_squash,sync)UIDs have to be the same on all computers for the permissions to work properly. In case they are different you can change them in YAST. After the changes files and directories will have the old user id set as the owner, so you’ll have to change the owner globally: chown -R --from=1001 marzena / Change also permissions for hidden files in the home directory: /home/marzena chown -R --from=1001 marzena .[a-zA-Z0-9]*NFS shares are accessed by other computers with automount, not configured in /etc/fstab!
