Network Installation of CentOS disk image via PXE
by vincenzo romero 11 Feb '08

11 Feb '08

Hello all, I've deployed new servers - installing new CentOS servers via PXE booting using its iso distribution stored on an NFS server. For certain server types; I'd like to install custom applications into a server and then generate an image of that server, and deploy again via PXE to another group of servers. Wanted to find out if anyone can forward any pointers to papers or links on: 1. Best and (cheapest) way to create disk image (that can be used for over the network installation over PXE) of an existing CentOS server with all its custom apps and packages ... would this be dd? would this take a long time? 2. Would like to find out if you can point me to a guide or doc - that specifically describes this process; most PXE install notes out there describe the PXE config setup and assumes an ISO image (to create a new server), as opposed to deploying a "ghosted" image of an existing server. 3. In a deployment of a "ghosted" image - would the DHCP automatically request for a new IP address upon completion of the installation on the target machine (since when I ghost the source machine, the network information will contain that source's machine IP address, MAC, etc. etc.) Thanks in advance .. -- best, Vince

NFS Exporting / not working ???
by Michael W Cocke 11 Feb '08

11 Feb '08

I'm fairly certain I'm not losing my mind, but.... I'm a very recent convert from fedora 7 to Centos 5. I had the / filesystem exported and it worked fine. Installed Centos, dropped the very same exports file I was using successfully into /etc, restarted nfs, and it won't allow anyone to access. If you mount it from a different system, the mount succeeds, but no files or directories show up and the ls just sort of dies a slow death. I managed to get it to work with samba, but nfs just won't happen. What am I missing?

Turning Wireless Radio on and off: how?
by Mark Weaver 11 Feb '08

11 Feb '08

Hi all, I've got a Dell Inspiron 1501 with a Broadcom 1390 Wlan mini card (integrated) wireless lan chipset. I've got an init script setup to activate the wireless connection at boot time, however when the system boots the adapter doesn't connect. I'm not able to get a connection until after the desktop is done loading and I run the script from the command line. After some log review apparently as the system is booting the radio for the wireless lan card is "off", so I need to know how to turn the wireless radio on just before the init script for the adapter fires off. How can I turn on/off the wireless lan radio? I'm using ndiswrapper and the dell windows driver for this wireless card. thanks, Mark

upgrade perl 5.8.0 -> 5.8.1
by Tony Barratt 11 Feb '08

11 Feb '08

Hello List, I have a few intel centos 3.9 boxes with perl-5.8.0-94.EL3 installed. This seems like a very early version of 5.8 perl. centos 4.6 has 5.8.1. Would it be sensible to just upgrade to this rpm? I want a stable platform for cgi. I suppose I could just try it, but these boxes are under a form of change control and I think I should ask for advice before going that route. Many thanks for any advice, Tony

Trouble Ticket System
by Jun Salen 11 Feb '08

11 Feb '08

Hi, Last year, I tried to installed and evaluate the following OSS web base trouble ticketing system. This is for me to track history on our IT related issues. Those that I tried are the PHP Ticket, DanPHPSupport, Epix Power Support, ruQueue, Ticket Express, OTRS, PMOS Help Desk and eTicket. From those, PMOS and eTicket are my top picks. I have problem installing OTRS the last time, so I am unable to evaluate that but will try later. The problem with PMOS is that the developer want to give up the project last time I checked. Aside from the mentioned above, can you suggest others that are better. Any advice from other experiences please. Thank you very much. junji aisalen.wordpress.com Linux Registered User #253162 CentOS User Send instant messages to your online friends http://uk.messenger.yahoo.com

Remember the unknown rootkit problem previously reported?
by Christopher Chan 11 Feb '08

11 Feb '08

If the attacker could get a shell, the attacker could have used this local root exploit to get the necessary privileges to install the rootkit. One reason why there seem to be few RHEL reports is that RHEL5 is not that widely available yet but lots of vulnerable Fedora/Debian installations are available.

tar: no, the file did not change while you read it
by Steve Thompson 10 Feb '08

10 Feb '08

CentOS 5.1, i686. I have a directory, say "foo", containing several hundred directories down to about six levels deep, and about 33,000 files. Periodically I make a tar archive of the whole lot: tar cf foo.tar foo and I often get from a few dozen to several hundreds of: tar: XXXXX: file changed as we read it followed by an exit status of zero. I am absolutely sure (100%, positive) that no files were changed during the period that tar was running: some of the files that are often flagged as changed have not been modified in many months, and have only been read by tar and the backup system. If I immediately repeat the tar command, it may succeed without any of these messages or flag a different set of files as changed, when again they have not. I'm sure from Googling that many have seen this. The system does also run Samba and the file system on which these files are resident is accessible from Windows clients, but none of these particular files are ever used from the Window side. The file system is also NFS exported, but again the files are not in use on any NFS client. What is interesting (that is, suspicious) is that on upgrading (clean install) the system from a previous incarnation of CentOS 4.6 (which also exhibited the problem) to CentOS 5.1, keeping the same tar version (1.15.1) and making no hardware changes, the incidence of these messages has _hugely_ increased. I have also seen a couple of repeated instances of "stat <file>" return changed times that differ from one another, and in all cases the file has not changed at all: the difference in the reported change times is always exactly 5 hours (which is my offset from UTC). I can't reproduce that at will. If anyone has a clue stick to beat me with, please do; it's getting a little old. Steve
