Re: kernel help
Heya, To remove the old kernel just delete /kernel and rename /kernel.old to /kernel. But note that you need to build the whole world (cd /usr/src/ make buildworld make installworld) before the kernel will be in sync with the rest of the system. If the kernel version is not in sync with the version of the 'world' (ie the user-land applications such as SSH, etc) then problems can occur. The FreeBSD manual has more information on the correct prodecure for upgrading a FreeBSD box.

Re: kernel help
Hey thanks James... it appears that that is what I am missing. I am fairly new to this kind of thing, so I guess I missed the buildworld and installworld part. That would also explain why the system tends to hang when I run older userland apps. So off I go a reading... -Geoff On Wed, 2004-10-06 at 23:37, James Pole wrote: Heya, To remove the old kernel just delete /kernel and rename /kernel.old to /kernel.

Re: enormous CPU load on 4.10 machine
Hi, I've redirected this to freebsd-stable because, as far as I can tell from reading the script, it has nothing to do with the networking code. This is strictly a scripting, and most likely process creation issue. Your script goes through each line, creating processes on just about every third line (each call to cat | awk etc.). I'm not a shell script whiz but I can tell you that you need to reduce the number of cat | lines if you want to improve performance. As to why this is a huge issue on 4.x (hence my post to -stable) and not on -current) I do not know. Good luck, George At Thu, 7 Oct 2004 09:20:04 +0300, donatas wrote: i've made a simple script for correcting about 2000 user files on 30 routers from the database. must notice that it works fine, but only on 5.2 Machines. on 4.8 4.9 and 4.10 it eats all the cpu resources.

Re: sk(4), 3C940 unknown reason hang

Re: kernel help
Alrighty so I am back up and running on my kernel.GENERIC.I started to read through the docs for doing a build world, and I don't think I am ready for that step yet. Mostly because this is a co-lo box that I only have SSH access to. Anyway now I want to make my changes to my GENERIC kernel so that I don't have to do the world thing. So I already CVSup'ed the /usr/src directory to 4.10, so that is bad for me. Can I whack the /usr/src directory and use sysinstall to load on the /usr/src files? If I tell it to go get it from ftp.freebsd.org, is it going to retrieve the latest (so 4.10) source or will it retrieve my default 4.9 source? I am trying to get a cd stuck in my box so that I can just do this off the CD, but thier tech support is a bit slow... HA. Thanks!

Heya, The best thing for you to do is to just take the standard CVSup file from:- /usr/share/examples/cvsup/stable-supfile Then update the following line:- *default release=cvs tag=RELENG_4_9 This should revert the source code to the 4.9 release -- and as a bonus all the security fixes for 4.9-RELEASE will be included as well. RELENG_4 will update you to the very latest code for FreeBSD 4.x-STABLE while RELENG_4_9 will update you to the latest patched code for 4.9-RELEASE. When you update your system will be FreeBSD 4.9-RELEASE-p99 (where 99 is the patch level which shows how many patches has been applied to 4.9-RELEASE) instead of just plain FreeBSD 4.9-RELEASE. You can verify this by running the `uname -a` command.

Re: enormous CPU load on 4.10 machine
Long listing, but we don't see the code. There is a po- ssibility that this machine does something you are not aware. Maybe someone else is using it for another purpose, hides processes via rootkit and leaves you without clue. It is not clear what has eaten your cpu. Could you make a little investi- gation in this direction? By aide or cops or... Go to logs and see if someone is doing a job.
