Any Linux Gurus here?

I need to write a CRON script to restart BIND on Fedora every day. For some reason it stops resolving, and I believe it is due to too much recursion(I know Bad setup to allow recursion). Problem is it is our primary name server for our customers. It has been a few years since I did a CRON but that part I can figure out, its the script I am having a problem with.

Which version of fedora?

BIND normally runs under the service "named". If you're just wanting to restart the processes nightly, you can restart that service. Older versions you can just use the init.d scripts (i.e. /etc/init.d/named restart) or the "service" command (/sbin/service named restart), providing you are able to run the cronjob as root.

 

I haven't played with the most recent version, but I seem to recall them moving away from both init.d and service commands, so they may not work.

Its an older version, 15 I think, and can use either service named restart, or /etc/init.d/named restart.

 

I set a crontab as 04 22 * * * /etc/init.d/named restart under root, so will see if that works.

OMG, is your car black? I'm fairly sure I saw it when walking in downtown Toronto between January and April 2014!

How can I check to see if the job ran? Is there a log other than the message one that would show the services stop/starting?

You could create a script, that appends a time/date stamp to a log file, and which also then runs the ".../named restart" command. Then put the call to your script in the crontab instead.

There might be other ones, but the messages file is probably the easiest if you're just check that it stopped and started.

 

There should be lines in /var/log/messages similar to:

named[8474]: shutting down: flushing changes

named[8474]: stopping command channel on .....

....

named[27196]: starting BIND ....

 

 

Depending on how BIND is setup, it may have it's own log. I can't really say for sure where that would be because it's often setup to run in a chroot jail.

I did find a log for cron and it is running on time, I will check the log tonight or later today when I have some time.

Holy shit yeah it is... And yes then you saw me.

 

I get people taking pictures all the time when they're stuck in traffic behind me or they'll stop on the street but this is the first time online!

Haha, I was rushing to class so I didn't stop to take a photo, not that my crappy phone camera could've captured the plate from a distance anyway :) I remember telling my friend about seeing your car, and remarking that the plate was "ironic" because Microsoft powers the infotainment system...

 

I was still on my old '08 Fusion at the time, and now I have an ice storm FFH. A shame we couldn't have met up to show off before I left Toronto.
