Description Tim Small 2001-02-20 11:17:36 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.18r3.5.29-w4l-IDE i686; en-US;
m18) Gecko/20010103

Any user may prevent "/etc/rc.d/init.d/named restart" from working properly.

Reproducible: Always
Steps to Reproduce:
1. execute /usr/sbin/named as an arbitary local user
2. as root, execute /etc/rc.d/init.d/named stop
3. as root, execute /etc/rc.d/init.d/named start


Actual Results:  named start fails (tried with bind-8.2.3-0.6.x)

Expected Results:  named should have started correctly, and user process
should be ignored, or killed.

Executing execute /etc/rc.d/init.d/named stop twice will work around this

The current version of bind can't be run by an arbitrary user.
