Re: Putting messages in dmesg or /var/log/messages
Have you looked at the logger command? It allows user use of the syslog service with control over severity and facility of the messages. Good luck!

Re: Putting messages in dmesg or /var/log/messages
Use logger and run the script from a separate init script with a dependency on the syslog startup script. Putting your message into a separate script will let you install it as an RPM and let init rearrange it as necessary. Rc.local is very early in the startup, so you can't use syslog until it's up. -Original Message- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of Bauer, Bobby (NIH/CIT) [E] Sent: Monday, July 01, 2013 2:00 PM To: LINUX-390@VM.MARIST.EDU Subject: Putting messages in dmesg or /var/log/messages Is there some way I can put messages in either dmesg or /var/log/messages.

Re: Putting messages in dmesg or /var/log/messages
Yeah ... 'logger' is pretty handy. Is available on other systems too. Following what David said, you will want the SYSLOG service up and running for 'logger' to have any effect. (According to design, the logged traffic would drop into oblivion if 'syslogd' is not running, so as to avoid lock-up or other bad things.) The dependency relationships are traditionally in comments at the start of each INIT script. 'systemd' changes the game. I won't waste time discussing that unless you are already suffering under its weight. -- R; On Mon, Jul 1, 2013 at 2:05 PM, Bauer, Bobby (NIH/CIT) [E] baue...@mail.nih.gov wrote: I did not know of the logger command.

Re: Putting messages in dmesg or /var/log/messages
Logger from rc.local seems to be working put I'll look into an init script. Never written one of those. Time to get out the books. It's pretty easy. Copy one of the existing ones (nfsd is a good one to start with -- it has dependencies already, so you can see how they work). For what you want to do, you just need to implement the start method, and mark it as dependent on syslog and network. You can just stub out all the other methods (stop, status, etc). Rc.local works, but having each one of these kinds of things separate makes system management a lot easier. The really nice part about making things like this separate scripts is that you can individually add or remove them w/o editing rc.local manually. You can also version-control them, and mass distribute them with yum rather than having to worry about stuff being outdated or how to edit a file. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For more information on Linux on System z, visit http://wiki.linuxvm.org/
