RE: [SLE] SuSE 9.1 painfully slow

> I started this because I had seen reports about the new kernel being much better > and faster so I thought that it would improve what was getting with that > computer. Are all those reports lies? No, but the 2.6 kernel may not be faster in a way that benefits your particular setup. Firstly, regardless of how fast a kernel is, a typical system spends more of its time running non-kernel code than kernel code. So a kernel that was magically twice as fast at everything would not make your whole system run twice as fast. Secondly, the major performance improvements in 2.6 are based around interactive response for workstations and multiway SMP machines; not low-end fileservers such as the machine you've set up. So while 2.6 is faster, it may not be faster in the areas that matter to you. Thirdly, IIRC the memory footprint of the 2.6 kernel is higher than 2.4. That might be enough to push the system into swapping more frequently, and that will kill performance. (Probably more important than all the above) you have not just replaced 2.4 with 2.6, but Suse 9 with Suse 9.1 - so all your user space programs have changed. If the memory footprint of your running system as a whole has gone up, then this will increase swapping and that will more than outweigh any performance gain from using 2.6 as against 2.4. [I should also note that I've seen a performance benefit from the latest 2.6 kernel updates from YOU, compared with the 2.6 kernel you get off the installation CDs.] You need to isolate the cause of the slowness to get further. Boot the system in runlevel 3 (no GUI), stop all unneeded services, and check the system's memory usage. Then you can start running some benchmarks to see if you have a real performance bottleneck, or if 9.1 was just eating too much RAM for your system to be comfortable.

How do I install a tar.gz file that begins with "install"
by John Boyle 03 Sep '04

03 Sep '04

To All: For Mozilla 1.7, I have found a plug-in that must be installed. Even though I was able, with a great deal of help from my SIG, in figuring out a regular tar.gz, this one starts out really differently. File: install_flash_player_7_Linux.tar.gz. ????? :-)

Internet connection
by aaimi＠libero.it 03 Sep '04

03 Sep '04

Hi all, I installed on my PC (Intel Penthium IV 2.8 Ghz - 500 Mb Ram - Network:3 COM Gigabit Lom (3C940) ) Suse 9.1 professional. I configured network board and then my local network work fine. The problem is the internet connection! When I try to start kinternet the connection start but it haven't success. This is the log file: SuSE Meta pppd (smpppd-ifcfg), Version 1.16 on root. Status is: disconnected trying to connect to smpppd connect to smpppd Status is: disconnected Status is: connecting pppd[0]: Plugin passwordfd.so loaded. pppd[0]: --> WvDial: Internet dialer version 1.54.0 pppd[0]: --> Initializing modem. pppd[0]: --> Sending: ATM1 pppd[0]: --> Sending: ATQ0 pppd[0]: --> Re-Sending: ATM1 pppd[0]: --> Modem not responding. pppd[0]: Connect script failed Status is: disconnected pppd[0] died: Connect script failed (exit code 8) I think that the problem could be that the kinternet try to use the modem (and I haven't a modem in my PC) to connect itself to the internet instead to use the network board and the local network. If it so, Where and how i can change this setting-out thanks in advace to everyone Andrea Aimi

Help with install of Solaris into SuSE
by Tom Nielsen 03 Sep '04

03 Sep '04

I've got SuSE 9.1 installed in my Sun box. I'm trying to install Solaris x86 also and dual boot. Solaris will go on a slave drive. My fear is if I install Solaris will it overwrite my GRUB? Has anyone else installed Solaris x86? If so, how did you do it? I'm booting off the Solaris CD and am trying to install it that way. Thanks, Tom -- Tom Nielsen Neuro Logic Systems, Inc. 1.805.389.5435 x18 www.neuro-logic.com

Linux has serveral Free Virus checkers, that will scan your email as it forwards it. I would suggest you setup a virus scan on the linux email server/router that handles your entire network. I don't bother, instead I have an ISP prorovder that does all the scanning/spamming work for me on all incoming/outgoing emails. > > -------- Original Message -------- > Subject: > Re: [SLE] Machine Building - > Nightmare Alley - Compatibility and > Upgrade > Date: > Thu, 02 Sep 2004 14:13:30 -0600 > From: > Ted Hilts <thilts(a)help-for-you.com> > Reply-To: > thilts(a)help-for-you.com > Organization: > help-for-you > To: > "Jerome R.

So I'll try to state it in a clear way. ALICE if for "SERVER FARMS" (to use a term we've agreed on already). It generates the complete configuration out "Templates". Theese templates are really not much more than text files with variables to be substituted. The Text files generate constitute all the entire configuration of a Linux machine. Alice keeps the templates and the "parameters" (machine configuration) in CVS to give versioning support. Now Last I looked was a late SuSE 8.x version. But like I said the entire setup (ALICE Server, ALICE WORKSTATION, Generated Server, CVS Template, etc etc ) was just too much effort for the 5 or so servers I had at the time. > Most of my LAN problems are not with Linux but rather with MS > operating systems.

Biggest problem was the 1.5 hours rebuild time after an "unclean" shutdown. On the other had, at a doctors office here in Switzerland, where they were doing heavy construction on the street infront of his door, I had a really bad case. THe Electricity Blinked. machine rebooted, software raid rebuild began. Then the electricity proceded to fail again 6 consectives times during the 6 consectutive rebuilds. A little hand work was required, (and a 150$ paid support call to SuSE, to confirm the right raid commands) but in the end I had no data loss. The software raid has matured quite a bit since thoose days. Today I trust myself to "hotadd", "hotdrop" disks from arrays, etc. etc. And most important, the rebuild happens in backgraound while the system is running... I have SATA RAID, and IDE RAID cards. I turn the RAID off where the card allows it, and define single disk raid-0 where the hardware cannot be turned off. And then use software raid. The software raid is faster, and I feel more confortable with it. And of course the clencher, I can take a SW-Raid disk, stick it in an external USB Box and get access to the data... > THANKS again for your reply and for taking the many hours to do so. > No Prblm. > TED > BTW: If you do look into ALICE, keep me posted, as I start getting more and more servers to support, ALICE is looking better, and better 8-)

KDM phone home ?
by Dan Am 03 Sep '04

03 Sep '04

Hi all, since the latest update(9.1) on startup KDM has a rather droll message in the log: <snip> Sep 2 13:41:36 buddha kdm[3406]: Cannot convert Internet address 4.0.1.64 to host name </snip> So I checked: host 4.0.1.64: Host 64.1.0.4.in-addr.arpa not found: 3(NXDOMAIN) O well...now what adress might this be, and why is KDM calling out. I am sitting behind two Firewalls, so there is really no reason :-( Anyone else seen this ? Regards Dan -- buddha 2.6.4-54.5-default 9:05am an 19:31, 1 Benutzer,

Changing kernel in the install distribution. How?
by Ermanno Polli 03 Sep '04

03 Sep '04

Hi. A brief summary about the question in the subject line. I discovered, in this ML, that my motherboard was non supported any more by SuSE, starting for 8.0 (the last one I could install from CD). So I thought to get the distro, build a new kernel for my system and substitute it in the distro. Then burning the CD and start the installation. But what must be changed in the distribution to make this work? Before, I tried to "force" YOU to get the new system from the hard disk, where the new distribution (btw.. 8.2, as a test to get to 9.0) is, but failed. "Could not mount" or something alike. Any hint? Thank you, Ermanno Polli
