user home

[zendril]

I'm using 5.0b12 but I think this is just a general question and not 5.0 related. Feel free to move if it is.

 

I want to login via ssh for a user account (don't like logging into unraid with root) AND have it work after a restart.

 

I installed unMenu and have ssh setup just fine.

In order to allow a user to login I had to

• change the shell from /bin/false
  
• create a /home/username dir
  
• update the users home to point to that
  

 

All of that worked just fine and I was able to login as the user account.

 

After a reboot of unraid it came up and all of those modifications were gone.

The /etc/passwd changes were reverted and /home was empty again.

 

Is this a 'feature' of unraid to wipe/reset all of this on a clean boot or something?

Is there a way to configure this so that it is persisted across restarts?

 

thanks,

You'll need to script your changes to run at boot. Nothing you change will persist on reboot.

Or you'll have to modify the bzroot.  If you have no clue what I'm talking about, best not.

FYI, unRAID is running in memory. So, everything you modified was changed in RAM and as soon as you reboot the original gets loaded from the flash drive again.

If you copy the passwd/shadow files back to the flash drive after your changes, they will be restored upon next reboot.

 

root@atlas ~ #find /boot -name passwd -ls

  5149    8 -rwxrwxrwx  1 root    root        1156 Nov 22 06:56 /boot/config/passwd

root@atlas ~ #find /boot -name shadow -ls

  7204    8 -rwxrwxrwx  1 root    root          66 Aug 15  2009 /boot/config/shadow

 

 

cp /etc/passwd /boot/config/

cp /etc/shadow /boot/config/

 

As for restoring /home you can either tar it up and write a script to untar it or rsync it somewhere before shutdown and rsync it back after rebooting.

 

storing /home on a cache drive in /mnt/cache/.home can work (Although it's not protected).

 

There is also the mount -o bind option where you mount some other directory on top of /home

 

Here's a chunk of my fstab.

 

root@atlas ~ #cat /etc/fstab

/dev/disk/by-label/UNRAID  /boot  vfat  auto,rw,exec,noatime,nodiratime,umask=0,shortname=mixed  0  0

/mnt/cache/.home          /home  auto  auto,rw,exec,noatime,nodiratime,umask=0,bind            0  0

 

root@atlas ~ #mount -v /home

/mnt/cache/.home on /home type none (rw,bind,noatime,nodiratime,umask=0)

 

You would need to alter the /etc/fstab in your go script or do the full mount command manually.

My cache drive is RAID1 so I'm not afraid of failure. although i do plan to switch my persistent directories to an SSD,

 

root@atlas ~ #mount -v -obind,rw,noatime,nodiratime,umask=0 /mnt/cache/.home /home

/mnt/cache/.home on /home type none (rw,bind,noatime,nodiratime,umask=0)

root@atlas ~ #mount | grep home

/mnt/cache/.home on /home type none (rw,bind,noatime,nodiratime,umask=0)

 

This is probably the easiest way as it only involves an extra command in the /boot/config/go script.

You can also choose a directory off /mnt/disk1/home or something like that of your choosing.

I really wish unRAID had a /homes directive for interactive user logins.

For how here are some solutions.

awesome replies guys..

 

thats what i wasn't aware of (being so new to unRaid) was that unraid is actually running memory..

 

i don't mind scripting it..

off to do some tinkering..

 

thanks!
