hi all
I run several RH3 AS taroon 4 but I have seen that kernels werent up to date...

on server20: 2.4.21-15.ELsmp #1 SMP Thu Apr 22 00:18:24 EDT 2004 i686 i686 i386 GNU/Linux

on server62: 2.4.21-27.0.2.EL #1 Wed Jan 12 23:46:37 EST 2005 i686 i686 i386 GNU/Linux

on server 6 : 2.4.20-28.9 #1 Thu Dec 18 13:53:00 EST 2003 i686 i686 i386 GNU/Linux

well the server 6 is really old...
I ran up2date....but the kernel version doesnt change...


do you know how to update this server to the last secure kernel?
thx

up2date -f --nox kernel or kernel-smp depending on if you have mutli processors or single

 

[fusioncroc]

After every kernel upgrade you will need to reboot into it just type reboot or shutdown -r now

ok thanks

and If I type up2date -u ?

what will the update do?

a technician of Matrix told me to type: up2date --nox --list

I didnt understand why...

 

[dave9000]

up2date -u will update everything that is not listed in the exclude list

kernels are excluded from automatic update so therefor you have to use the -f --nox

Will this command "up2date -f --nox kernel" work correctly on a CentOS 4.2 server?

Celliott,

The command for CentOS would be
"yum update" for a full list of updates, or "yum update kernel" I believe to do just the kernel.

but you'll have to import the proper gpg key. Instructions for this can be found at http://www.centos.org/modules/smartfaq/faq.php?faqid=30
