Changing the mount options for /tmp

[jez9999]

Hi,

After securing my server you applied the mount options 'noexec' and 'nosuid' to my /tmp directory. I'd like to temporarily remount it without those options. How can I do this?

I've tried 'mount -o remount,rw,bind,exec /tmp' and 'mount -o remount,rw,bind /tmp', but neither has changed anything. I also tried changing the entry in fstab and restarting but that didn't change it either.

To do that you would have to remove the line about /tmp from your /etc/fstab file and restart your VPS.

Andre,

It would seem that something other than /etc/fstab is controlling the /tmp mounting, though. When I remove that line and restart, the mount is still there, exactly as before. It's likely something to do with your security setup; do you do anything else that causes /tmp to be mounted that way?

The /etc/fstab is the only thing that control it, but it could be that once it's been set that it stays that way somehow (I have to add that I haven't tried to remove a partition like that before, mainly because usually it's not necessary to do so).
