For some of these tests (multiple tests within each package) the newer kernel was faster, but for many of them, the older kernel was faster. For example, hdparm -t on the new kernel gave me 40MB/s on a 3disk raid5 array, while on the older kernel I got 150MB/s from hdparm -t. -- Jesse Keating RHCE MCSE http://geek.j2solutions.net Mondo DevTeam (www.mondorescue.org) Was I helpful?

Re: X Window System, Minimum Installation
Hi I have setup many "headless" servers with a few X-apps, as long as the application's dependancies are met they should work. I always put Nedit on my servers, it also requires "motif" libraries. If you want to know what a program requires to run do somting like this : $ rpm -q --requires nedit openmotif /usr/bin/desktop-file-install rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rpmlib(CompressedFileNames) <= 3.0.4-1 libc.so.6 libc.so.6(GLIBC_2.0) libc.so.6(GLIBC_2.1) libc.so.6(GLIBC_2.1.3) libICE.so.6 libm.so.6 libm.so.6(GLIBC_2.0) libSM.so.6 libX11.so.6 libXext.so.6 libXm.so.3 libXmu.so.6 libXpm.so.4 libXp.so.6 libXt.so.6 $ rpm -q --provides openmotif libMrm.so.3 libUil.so.3 libXm.so.3 openmotif = 2.2.2-12 $ rpm -q --whatprovides /usr/bin/desktop-file-install desktop-file-utils-0.3-3 $ rpm -q --provides desktop-file-utils-0.3-3 desktop-file-utils = 0.3-3 ...and so on... So in total, nedit requires : rpm :-) openmotif desktop-file-utils glibc XFree86-libs I hope this helps, using these methods you should be able to pair down your RPM based system.

Re: USER can't use Modem
Hi Dusan, Further to my late posting. I have recovered /dev/modem and made it symbolic linked to /dev/ttyLT0. Modem is now working. Get back to your advice. Some thing strange happened. It works but is not stable. Konsole window $ su - password # chmod +s /usr/sbin/kppp (return) # (nothing visible recognised) exited Konsole window KStart -> Extras -> Internet - > KPPP kppp started without asking for password First I configured another kppp for USER and made it worked Started Konsole window $ kppp kppp started without asking for password $ cu -l /dev/modem Connected. AT OK ~[localhost]. Disconnected. $ After testing several times, the problem returned KStart -> Extras -> Internet - > KPPP kppp started asking for password Started Konsole window $ kppp kppp started asking for password Rebooted PC (also tried - shutdown and re-start) Started Konsole window $ su - password # chmod +s /usr/sbin/kppp (return) # (nothing visible recognised) Problem could not be solved.

Re: USER can't use Modem
Add the user to group uucp. That should take care of it. As you can see below only user root and group uucp can access the serial ports. crw-rw1 root uucp 4, 64 Aug 30 2002 /dev/ ttyS0 crw-rw1 root uucp 4, 65 Aug 30 2002 /dev/ttyS1 crw-rw1 root uucp 4, 66 Aug 30 2002 /dev/ttyS2 crw-rw1 root uucp 4, 67 Aug 30 2002 /dev/ttyS3 ... Do NOT change the permissions or ownership, or you will create security problems.
