What does system-config-netboot do???
by clemens＠dwf.com 07 Jan '09

07 Jan '09

Having given up on getting system-config-netboot to work (reading the pointers I have received to the wiki, say it is broken), I have the simple question "What is it suposed to do???" I have tried to look at the code, but its written in python and I cant follow the logic. Im sure I can easily do whatever is necessary at the command line If I just knew what it was trying to do with its cute user interface (and dont get me started on broken, cute, user interfaces...) -- Reg.Clemens reg(a)dwf.com

High softirq usage in Centos 5
by Oguz Yilmaz 07 Jan '09

07 Jan '09

Hi, I have a machine under heavy network traffic. Kernel is Centos kernel 2.6.18 SMP 32 bit. Ethernets are 05:00.0 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01) 05:00.1 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01) 06:01.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05) 06:02.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05) The mainboard is with Intel 5000 series chipset Asus board. When I use 2.6.9 kernel with the same location and traffic I have had no softirq usage. Also in 2.4 Centos 3 machine I have had no softirq usage. With the same location and traffic I have softirq usage %25: Cpu0 : 2.0%us, 2.0%sy, 0.0%ni, 71.3%id, 0.0%wa, 2.7%hi, 22.0%si, 0.0%st Cpu1 : 1.0%us, 1.3%sy, 0.0%ni, 79.7%id, 0.0%wa, 1.3%hi, 16.6%si, 0.0%st I have no extra parameters in grub.conf. Is it a known problem? What do you suggest?

Anaconda crash during Centos 5.2 installation.

Hi, I'm trying to install Centos 5.2 on an "old" machine in graphical mode (to use LVM) but anaconda crash. I made several tries with various installation resquest (the last is "Server", "Customize after installation") unfortunately, it's reproductible: Traceback (most recent call first): File "/usr/lib/python2.4/site-packages/yum/sqlitesack.py", line 42, in newFunc raise Errors.RepoError File "/usr/lib/python2.4/site-packages/yum/sqlitesack.py", line 596, in searchPrco results.extend(self.searchFiles(name)) File "/usr/lib/python2.4/site-packages/yum/sqlitesack.py", line 40, in newFunc return func(*args, **kwargs) File "/usr/lib/python2.4/site-packages/yum/sqlitesack.py", line 648, in searchProvides return self.searchPrco(name, "provides") File "/usr/lib/python2.4/site-packages/yum/packageSack.py", line 399, in _computeAggregateListResult sackResult = apply(method, args) File "/usr/lib/python2.4/site-packages/yum/packageSack.py", line 267, in searchProvides return self._computeAggregateListResult("searchProvides", name) File "/usr/lib/python2.4/site-packages/yum/depsolve.py", line 149, in whatProvides pkgs = self.pkgSack.searchProvides(name) File "/tmp/treedir.8196/instimage/usr/lib/anaconda/yuminstall.py", line 388, in _provideToPkg for po in self.whatProvides(r, f, v): File "/tmp/treedir.8196/instimage/usr/lib/anaconda/yuminstall.py", line 461, in tsCheck dep = self._provideToPkg(req) File "/tmp/treedir.8196/instimage/usr/lib/anaconda/yuminstall.py", line 429, in resolveDeps unresolved = self.tsCheck(unresolved) File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 585, in buildTransaction (rescode, restring) = self.resolveDeps() File "/tmp/treedir.8196/instimage/usr/lib/anaconda/yuminstall.py", line 1265, in doPostSelection (code, msgs) = self.ayum.buildTransaction() File "/tmp/treedir.8196/instimage/usr/lib/anaconda/backend.py", line 177, in doPostSelection return anaconda.backend.doPostSelection(anaconda) File "/usr/lib/anaconda/dispatch.py", line 201, in moveStep rc = stepFunc(self.anaconda) File "/usr/lib/anaconda/dispatch.py", line 124, in gotoNext self.moveStep() File "/usr/lib/anaconda/gui.py", line 1018, in nextClicked self.anaconda.dispatch.gotoNext() RepoError: None Can somebody tell me where is the problem?

CD burning issues & questions
by MHR 06 Jan '09

06 Jan '09

I have been having some strange results trying to burn CDs under CentOS. I don't think they are hardware related because I have had some success, in fact most of this usually works. I use k3b for most of my CD and DVD writing - it seems to work fairly well (well, except for wrecking my installation a few weeks ago when it crashed my installation and I had to reinstall to get it back, but that's old news). Yesterday, of my work desktop (32-bit), I tried to burn a CD with k3b. The system hung as soon as I clicked on the start button in the burn menu. I did not want another case of wrecked system, so I rebooted (no other way to interrupt it) and all went well, except that I didn't even try to burn the CD. (I used my other, backup desktop, and it worked fine over there - hmm....) Then, last night, on my home desktop (64-bit), which is usually solid as a rock, no problems whatsoever (I said "usually"), I had similar problems, though not quite as bad. I was trying to erase some CD-RWs, and I kept getting errors, both from k3b and cdrecord, claiming that they could not lock the drive for exclusive access (because another process was accessing the device). This is really annoying because I've tried this one several CD-RWs, and they all get the same error. Since k3b doesn't include a facility to add data to an already written CD or DVD unless there's a specific project for it (which I don't have 'cuz the CDs were written under Window$ or with projects I didn't keep). Any ideas/suggestions? Thanks. mhr

Log File Reviewing
by Joseph L. Casale 06 Jan '09

06 Jan '09

I need to review a logfile with Sed and cut out all the lines that start with a certain word, problem is this word begins after some amount of whitespace and unless I search for whitespace at the beginning followed by "word" I may encounter "word" somewhere legitimately hence why I don't just search for "word" only... Anyone know how to make sed accomplish this? Thanks! jlc

Anyone got Diskless BOOT working under CentOS ???
by clemens＠dwf.com 06 Jan '09

06 Jan '09

Im trying to get a diskless boot set up under CentOS 5.2, and having no luck at all. I am to the point of running system-config-netboot, and whatever information I put in, I get an error message. Responding to the 2nd button on the first popup, which asks for NFS info, I put in the IP address of the current machine (the machine that will hold the boot images for the diskless machine) and the root directory for the diskless machine, viz /diskless/i386/CentOS5.2/root Which has a copy of my root file system, and in particular has a /boot subdirectory. When hitting FORWARD, I get the error message: The diskless subdirectory must be NFS exported and contain a boot subdirectory. Now Ive checked, vsftpd is running, nfs is running, and the above directory (and others) are in the /etc/exports file. I did this several years ago under Fedora, and dont remember having problems like this. Has ANYONE done this recently, and do you remember what you had to do??? I would REALLY like to exchange some e-mail with you. It would be nice if there was an example somewhere. -- Reg.Clemens reg(a)dwf.com

I have also compiled the source code with the required gtk2, glib2, pango, cairo, atk, fontconfig, freetype2 and I still receive the same error.
