minute cron

Tue, 03 Apr 2012 01:08:05 -0700 Post Comments

anacron is used on desktops and laptops which are not powered 24/7 - it
executes the missed cron jobs soon after boot. It doesn't replace the
regular crond, which executes jobs if the machine is up at the scheduled
time.

If it's that rough, then see man 1 sleep.

centos 5 and 802.1x on wire

He's referring to 802.1x, which is a form of port-based network
access/admission control (NAC). It uses EAP (Extensible Authentication
Protocol - actually EAPOL [EAP over LAN]) to require authentication
before the supplicant is given access to the LAN.

That's the theory - but I've no idea how it works in practice with CentOS.

directory entry and hence requires write permission on the directory, not
the file - which you have as a result of the "other" permissions on the
directory:

drwxrwxrwx   7 root root  4096 Mar 10 13:35 temp
