Hi all,

 

I followed this guide to install dnsmasq on my box up until about step 7 when I realised that actually I wasn't too fussed about doing it anyway. I've since spent the best part of two days trying to uninstall the damned thing! It's not particularly in the way but I feel that my failed attempts have highlighted a flaw in my underlying knowledge of unRAID, so I'm reaching out for help.

So far I have done the following:

• 'removepkg dnsmasq'
  • This resulted in:
    'Removing package /var/log/packages/dnsmasq-2.79-x86_64-1...
    Removing files:
    cat: '/var/log/scripts/*': No such file or directory'
  • So I tried 'removepkg /boot/config/dnsmasq/dnsmasq-2.57-i486-1.txz' which removed a bunch of stuff as I'd expect with no errors.
• After this there were still a bunch of files & directories left over, for example:
  • /etc/dnsmasq.d
  • /etc/dnsmasq.conf
  • /etc/rc.d/rc.dnsmasq
  • /usr/sbin/dnsmasq
  • /var/lib/libvirt/dnsmasq/
• So I deleted these, along with
  'installpkg /boot/config/custom/dnsmasq-2.57-i486-1.txz
  cp /boot/config/custom/dnsmasq.conf /etc
  chmod +x /etc/rc.d/rc.dnsmasq
  /etc/rc.d/rc.dnsmasq start'
  from my go file, and deleted the dnsmasq directory I'd made inside '/boot/config/' which contained the downloaded package.

 

As far as I can tell, there should now be nothing on my system that resembles any remnants of dnsmasq…
… However as soon as I reboot, all the files listed above have come back (except anything under '/boot/config/dnsmasq/' and the changes to my go file), and then whenever I start the array, the dnsmasq process starts back up. I've been trying to research and dig further but I have truly exhausted myself now, so I'm hoping someone can point me in the right direction!

Many many thanks in advance

Hit submit too soon :facepalm:

I can't really help with the clean up but I can tell you that what you installed was a 32-bit package, which isn't supported by 64-bit unRAID 6. That guide is four years old and unRAID has come a long way in that time.

Search your USB stick for that file or any other file name that you downloaded, and delete it.

 

Failing that, do a google search for files that should be on an unraid usb and find the wiki that describes in detail what is there by default.

Here is the link to a WIKI to findthose:

Thanks everyone for your suggestions so far... I've diffed my flash disk with a bone stock one and removed everything I could possibly think is dnsmasq related. Unfortunately I'm pretty certain that it's not something on the flash disk that unraid boots from. Even with a new USB stick and a fresh install, as soon as I start the array with my disks, I see dnsmasq stuff in the logs and the files come back.

 

Here's those logs:

If I remove the disks from the array and give it a blank one just so I can start it, the above doesn't happen.

OK.  First thing.  The list of files and/or directories that you list above are actually on a RAM disk.  (Very time you boot unRAID , its sets up this RAM disk and INSTALLS   the complete Linux OS from scratch and then installs the files that unRAID requires to run.  So deleting those files is futile.  They will just be reinstalled every time you reboot.  

 

Second thing:  Make a backup copy of your Flash Drive NOW!!!!

 

Now, I had a quick look at the link you provided in your first post and found this quote: 

 

Quote

The default Main Menu is located in /mnt/cache/tftp/pxelinux.cfg and it's called default.

 

This means that the install process that you followed installed folder(s) on your cache drive  (that is what the   /mnt/cache   is pointing to).

 

I did NOT study that install procedure in detail but you are going to figure how to uninstall that package from those instructions.  If all else fails, delete that directory---   tftp   ---- from your cache drive. (Hopefully, it is only using one directory to store everything in!) 

 

At the very last resort, you may have to reformat your Flash Drive and reinstall unRAID.  Use this section of the version 6 Upgrade WIKI to determine which files to copy over from your backup:

Hope this helps

 

EDIT:  After you have make a backup of your Flash Drive, delete the   go  file from  the  config folder/directory on the Flash Drive.  Copy the default   go   file from a a current version of unRAID distribution in its place.

Thanks for your time and effort helping me @Frank1940 - Much appreciated! I'm starting to think I've been a bit of a numpty... Is some manner of dnsmasq already packaged with unraid? Precleared drives, reformatted flash, and the dnsmasq events in my log still happen.
