[SOLVED] /tmp directory changing permissions after reboot (slackware 15.0)

gattocarlo · 03-10-2024, 07:21 AM

Hello,

I've recently upgraded my home server to slackware 15, a new totally fresh installation.

Everything is working properly but after a reboot (I think, but I'm not sure), the /tmp directory was set as

Code:

drwxr-xr-x

instead of

Code:

drwxrwxrwt

I tried to understand how and when that happened (it occurred twice, so far), but with no result. Any idea?

Thanks for your kind attention.

Best,
andrea

Did you install a bad package? 'grep ^tmp /var/adm/packages/*' should return only the aaa_base package.
Any script run as root can do anything. Did you install something in addition to slackware packages?
If /tmp is not a directory in the root file system but a mount point, is the line in /etc/fstab correct?
When you see the wrong mode, 'stat /tmp'. Does the Change time ring a bell? (Although, for example, new files in /tmp change it too.)
A broken cron script to clean /tmp.

thanks a lot!

The culprit is the asterisk.SlackBuild (from slackbuilds): it seems like the build process of asterisk creates a /tmp file during installation, with the obvious consequences...

thanks a lot for the pointer.

hi andrea,

I just tried to build asterisk from SBo but there's no /tmp directory in the final package nor in the filesystem as a result of the build (I'm not able to reproduce what you describe)...

SBo comes with 16.15.0 and when I went online with my server I upgraded to 18.21.0, using the SBo script. It is not a bug in the script, I think, since with asterisk-18.1.1 everything was fine. But when building 18.21.0 I find a tmp/ in /tmp/Sbo/package-asterisk/.

This can happen when something is untarred in /tmp that changes the permissions of the current directory. An example of something like this is the Firefox source tarball.
