Probably slightly easier: are you doing a specific job/connecting a specific piece of hardware/... when your kernel panics? That can give you a clue where to look. Sjoerd

Sure, a very efficient way to do some bug hunting is just to copy-paste the error in google's search, after removing some locale file names that are probably not unique. Usually that gives you a "this is wrong, and this is what you can do about is". When it doesn't is when the fun begins... Sjoerd

My answer is Google is your friend. I am not about to do your research for you. This is a Help List but it is expected that the person asking for help has already tried other sources before asking for help here. Microsoft help costs $, unless you search the net for answers. Linux answers, be they good or bad, abound on the net. Ask the right question and you will get answers. You should have learned some of the questions to ask, Google, by all of the answers you have received in this thread. Happy researching....

But googling for "how to parse linux log files" is not getting me any good learning material. I had hoped that the gurus here might have come across such a resource in their travels. > Happy researching.... > Thanks, Wayne, it often is! -- Dotan Cohen http://bido.com http://what-is-what.com -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

It has a "plugin" mechanism to include filters for the exclusion. Still posts plenty. -- http://www.iki.fi/jarif/ You possess a mind not merely twisted, but actually sprained. |
