Edit /etc/grub/grub.conf (or wherever grub.conf is located ($locate grub.conf)

Either comment out the old kernel or remove the lines entirely.

Whenever you get a new kernel, you should leave the old kernel intact, as well as leave the reference to it in the boot loader, that way if the newer kernel has problems/is unstable, you can always boot into the old kernel. I keep at least three kernels on my system. If you do want to remove the old kernels, rm them to claim your space back.

sj4569:

There is a howto around here somewhere about upgrading the kernel.

You'll find a directory called /boot and that has the GRUB configuration file on it, it's called grub.cnf or similar. Read it with a text file, you'll be able to remove the entry for the kernel you don't want.

If the old kernel was installed from rpm then you can probably uninstall it using the rpm command in terminal. Otherwise, you'll notice that you have directories and files named for each kernel installed - these would need to be deleted... carefully.

CAVEAT: You *want* two kernels! The earlier version will now act as a backup in case you stuff up somewhere. Having my old kernel there has saved my bacon on three occasions while I was learning how to make my new kernel un-bootable.

For those who wonder what use RHN registration is now there will be no more updates... consider, some of us do not have completely up to date systems. Some of us do not have every utility et al installed. It would be nice to collect all these things methinks.

Not so much a problem, as a question..

I'm wondering if its possible to configure up2date to change the default configure parameters on a package. that is, in my situation, postfix to be installed with mysql support.

I ran into an issue whereas, I ran up2date and it apparently updated and rebuilt postfix, however without mysql support, so my entire virtual mail subsystem stopped functioning.

Is there a way to make sure that when up2date notices that postfix is out of date, it will compile it with the appropriate mysql support for my system, and if so, How?

Thanks.

What it does is look through the available packages and decides what is newer according to it's versioning. It cannot get stuff unless it's offered.

This is basically why the source rpm is available. You can rebuild the .src.rpm file to create a custom rpm.

What you may wish to do is configure up2date to download sources and not install anything. This way you can decide what to do, as well as being able to rebuild your own source rpm files.


If your using Fedora remember that it's basically a testbed for RHEL and updates are subject to break or remove support for one thing in order to fix and or add support for another, or a temporary bug that's not found and fixed yet.

Normal distros would usually just make bug and security updates and an actual upgrade or change of support for one app over another would be another release version.

With the possible exception of a legal dispute that would require removal of some piece of code.

To have only one kernel showing in GRUB, you edit the grub.conf file - commenting (or deleting) out the entire section referring to the version you don't want to see. Your old kernel will be living in a directory named for the version number, delete that directory will erase the old kernel. (Presumably, if the old kernel came from an rpm install, then the rpm uninstall will remove it. I've never tried this myself...)

CAVEAT: it is goot form to keep the old version of the kernel around: you will very likely want to fiddle with the new kernel and occasionally (read: often enough to smart) you'll stuff it up. Knowing you have an undamaged kernel around adds to confidence levels

Normally, folk are most interestid in the newer kernel being the default. If this is the issue, edit the grub.conf file to put the newer kernel first. No sweat.

hello iv allso got that up2date problem with redhat 9 i opend a terminal logged in as root and typed
"wget -q -O - https://rhn.redhat.com/help/new-cert.sh | /bin/bash"
the feedback was
"The file /usr/share/rhn/RHNS-CA-CERT has already been updated.
No further action is necessary."
so i then typed in
"up2date up2date"
the feedback was
"[root@master Desktop]# up2date up2date

Have you seen...

Also - google the error message.

No reply sometimes just means that folk think the answer is obvious. So try saying what youve tried as well.

ok what i did was i just went back to the red hat network now when i logged in went to "systems" it said no systems registerd dont get it i was registerd befor i used up2date in the past any way i aint got a clue how to register i thought if i could login i was registerd .obviously i was wrong

hello again when i type" up2date --register"
i get error message
There was an SSL error: [('SSL routines', 'SSL23_WRITE', 'ssl handshake failure')]
A common cause of this error is the system time being incorrect. Verify that the time on this system is correct.
well i went in to my bios the time was incorrect iv now put it right and i still get the same error messag
thanks

hello again if i type "rpm -Fvh up2date-*.rpm"
i get
[root@master Desktop]# rpm -Fvh up2date-*.rpm
1:up2date ########################################### [100%
i think this is good

but when i type "rpm -Fvh up2date-3.1.23.2-1.i386.rpm up2date-gnome-3.1.23.2-1.i386.rpm"
it just goes back to "[root@master Desktop]# rpm -Fvh up2date-3.1.23.2-1.i386.rpm up2date-gnome-3.1.23.2-1.i386.rpm
[root@master Desktop]#

why is it when i type
"up2date-p"
im told i need to register so i type
"up2date --register"
im then back to square 1 cause it says
"[root@master Desktop]# up2date --register
There was an SSL error: [('SSL routines', 'SSL23_WRITE', 'ssl handshake failure')]
A common cause of this error is the system time being incorrect. Verify that the time on this system is correct"

ok what i did was download ssl certificate i then did
"[root@master Desktop]# md5sum new-cert.sh
8da6aef05771287bd43b5366241d75e0 new-cert.sh"
i then did
"[master@master Desktop]$ su
Password:
[root@master Desktop]# /bin/bash new-cert.sh
The file /usr/share/rhn/RHNS-CA-CERT has already been updated.
No further action is necessary.
[root@master Desktop]#
so am i right to say the only problem i have got is that when i go in to redhat click on systems it says i have no systems registerd. if that is my only problem how do i register i realy could do with some extra help please
