[SOLVED] Permission issues with /var/cache: Contradicting information.

Hi,

[root@httpd /]# ls -lha /var/
total 16K
drwxr-xr-x 1 root root  132 May 25 08:51 .
drwxr-xr-x 1 root root  146 May 25 17:20 ..
drwxr-xr-x 1 root root   66 May 25 09:08 cache

[root@httpd /]# ls -lha /var/cache/naemon/
total 0
drw-rw-r-- 1 naemon naemon 32 May 25 10:41 .
drwxr-xr-x 1 root   root   66 May 25 09:08 ..
drw-rw-r-- 1 naemon naemon  0 May 25 08:55 checkresults
srw-rw---- 1 naemon naemon  0 May 25 10:41 live

[root@httpd /]# sudo -u naemon touch /var/cache/naemon/test
touch: cannot touch '/var/cache/naemon/test': Permission denied

That should sum up why I am confused. Naemon is a fork of Nagios (see its arch wiki page).

It needs access to that folder for obvious reasons, but even though it's owned by the group and user, and has the correct write permissions, it cannot write to it.

first off, dirs should almost always have execute permissions.

And secondly, make sure the immutable bit isnt set, as this might prevent you from writing/changing things, even as root AFAIK. See lsattr and chattr for that. The permissions thing seems much more likely though. Try sudo chmod +x /var/cache/naemon and see what happens.

That was the issue. Thanks. I did not realize that about directories.

I've never heard of the "immutable bit". Time to read some web pages.
