A Number of SuSE 9 Issues

meyankee · 12-31-2003, 01:44 PM

There was a thread on this in the suse-e mailing list. It seems that the problem can be caused by IPV6. disabling IPV6 should resolve the problems with slow loading and freeze ups. I DO NOT recomend stopping the firewall.

You can use the "nmap" portscanner to see what is open.

Use "lsof | egrep "TCP|UDP" to show files opened by processes on those TCP & UDP ports. The service name is usually the first or last words on each line.

Then use chkconfig and shut them off. or "ps ax | grep <the-name-of-the-service> " to get the service's process id number (pid). The pid is the first number on each ps ax line. Then "kill -9 <service-pid-number> ".

Or, uninstall those services/programs in Control Center > YAST2 > Software > Install or Remove Software. You might need to go there anyway to install nmap, cool toy.

Thank you, number9, for this useful post. But it still doesn't tell me what is needed. For example my old SuSE 6.4 used Apache to access its help system. You can imagine what happened when I disabled it and had to re-enable it without the help pages ... a well, I guess its trial and error again, particularly error

I've got the same problem with Mozilla and all browsers based on it (Epiphany, Galeon, Firebird) - when I enter any text in the address list or in a form the browser freezes.

Now, how do I turn off IPV6, if that's what causes the problems, and are there any side effects?

To disable IPV6:

In /etc/modules.conf make the following change, replace
alias net-pf-10 ipv6
# alias net-pf-10 off
with
# alias net-pf-10 ipv6
alias net-pf-10 off

Run depmod -a && modprobe -r ipv6

(If modprobe can't unload the ipv5 module then reboot)

I have not heard of anyone having problems after doing this change.

Thanks a lot, that really did it. There seem to be no problems, and Mozilla is working fine.

Thanks again!

Hi number9, THANK YOU

,

your way worked like a breeze, much easier than I anticipated due to the "chkconfig" utility, thus making trial and error so much more palatable in the end. Incredible what number of tools lie hidden in the system, I wish I knew how to find them all

.

That, and where the changes wrought by chkconfig go, i.e. the target script for boot-up it changes (using the on and off switches). I'm usually working from level 5, and SuSE must have a script to call the scripts from /etc/init.d/rc5.d which in itself must be altered by chkconfig. I still have to find that master-script to learn how to do it by hand.

Thanks again, you have been most helpful.

Hi,

I have a identical problem, normaly I work with KDE and very often the panel freezes but in my case it does not unfreeze, I've once waited for about 2 hours before switching off/on. The odd part is that everything is still working but the panel is freezed up, but when I push the off buton it appears that it starts a logoff and the panel is still freezed after a while I have to switch off and on to reboot the machine. I have a Gygabyte NVIDIA Gforce2 MX 400 that I think is causing this problem because suse does not have the appropriate driver for it. If anyone can help me it would be appretiated.

Thanks
