Centos 5.0 x86-64 install crashes with Realtek 8111B Ethrenet
by Richard Chapman 26 Jun '07

26 Jun '07

While installing Centos 5.0 x86-64 on a Gigabyte GA-945GM-S2 motherboard which has Realtek 8111B Ethernet chip - Anaconda crashes. I select the option to use the Centos online repository for extra packages - I am asked to enter IP address etc. The drop box to select the Ethernet interface is blank. If I enter valid IP address and gateway - anaconda crashes and the system reboots from CD. I think that the NIC chip is not correctly detected by anaconda - and there must be a problem in the logic which allows anaconda to try to connect to the network without any available network adaptor. Incidentally - I also use a version of Linux called Trinity Rescue. The current version of trinity used kernel 2.6.19.2 - and this detects and runs the same Ethernet chip fine. Maybe the newer kernel fixes the problem - or maybe the problem is specific to x86-64 architecture. In Bug report 0001947 someone reports he fixed this problem with a new driver from realtek and/or redhat. I have downloaded this driver - but can anyone point me to instructions on how to compile and install it? I have built a Centos 5.0 without network support. Alternatively - does anyone know when we expect a Centos 5.1 release? Is there a beta I can get hold of before the release? Alternatively - can I download updates for the Centos 5 from a yum repository using a working cetos 4.4 installation - then use yum or rpm to install a new kernel or driver on the Centos 5.0 system? Can anyone suggest were I would find instructions on how to do this? Thanks Richard.

Exe file size is chaning during runtime
by balajisundar＠midascomm.com 26 Jun '07

26 Jun '07

Dear All, We have observed the exe file size getting changed during run time of the system in CentOS. We are using CentOS 4.4 release. We have taken "strings" of the original "exe" and changed "exe". Then we compared the strings output of the two. The difference is given below. We are not sure why this is happening. Can some one throw light on this. diff oldExeStrings newExeStrings 1a2,8 > MzFX# > PzFr > MzF` > MzFm > MzF% > MzFXi > MzF 163a171,182 > libssl.so.4 > libcrypto.so.4 > libkrb5.so.3 > libcom_err.so.2 > libcrypt.so.1 > libresolv.so.2 > libnsl.so.1 > libpthread.so.0 > /lib/ld-linux.so.2 > libgssapi_krb5.so.2 > libk5crypto.so.3 > libz.so.1 --Regards S.Balaji

ipmi regression in 4.5?
by Gavin Carr 26 Jun '07

26 Jun '07

I've been monitoring CPU temperature on a few Dell SC1435s running CentOS4 via OpenIPMI and 'ipmitool sdr'. It's been working very nicely, but the upgrade to 4.5 not so long ago seems to have broken something: # ipmitool sdr type Temperature Temp | 01h | ns | 3.1 | Disabled Planar Temp | 04h | ok | 7.1 | 30 degrees C Temp Interface | 53h | ns | 7.1 | Disabled The disabled sensors above used to work fine, and there have been no config changes or bios upgrades or anything. All machines affected post 4.5. Any suggestions? Cheers, Gavin

How can I set NIC duplex before installation?
by John Horne 26 Jun '07

26 Jun '07

Hello, I have installed CentOS 5 onto a server this afternoon using NFS. The NFS 'server' has a 100Mb/full-duplex interface, the server I installed CentOS on to has 4 x 100Mb interfaces. However, the installation was painfully slow to start with, and by using ctrl-alt-f2/f4/f5 I could see that contact with the NFS server was intermitently failing. Soon after some of the packages had installed the 'ethtool' command was then available, and I could see that the (installation) server NIC had been set to 100Mb but at half-duplex. This was causing numerous collisions and errors on the NIC interface. As soon as I reset the NIC to full-duplex (via ctrl-alt-f2 and using ethtool), then the installation speeded up and seemed to cause no more errors. My question is, how can I tell anaconda to set the NIC interface options such as speed and duplex? I have another server to install which has 2 x gigabit NICs and 2 x 100MB NIC's. My concern is that anaconda will again use wrong NIC parameters, and the installation will again be very slow. Surely it is possible to set the NIC options?

yum version of Debian's sources.list?
by RR 25 Jun '07

25 Jun '07

I'm hoping to find the CentOS version of Debian's /etc/apt/sources.list "yum install program" isn't running properly on one server, and I'm wondering if the repositories (or whatever the yum equivalent is) are pointing to good places. Thank you

Has anyone gotten KDiff3 to work on CentOS 4.X?
by Alfred von Campe 25 Jun '07

25 Jun '07

The Subject: line says it all. I haven't been able to find a KDiff3 RPM (http://kdiff3.sourceforge.net) that will install on CentOS 4, and I am also having problems building it from source (the application that is, not the RPM). I have some users who really want to use KDiff3, so any help/hints are appreciated. Thanks, Alfred

iptables rule (MAC filtering)
by Jordi Espasa Clofent 25 Jun '07

25 Jun '07

Hi all, I've a CentOS box which as two NIC; this box is also a router for LAN subnet: ------------------------------------ | eth0 (external) 172.0.0.1 | | eth1 (internal) 192.168.1.1 | ------------------------------------ | LAN clients (192.168.1.2+) I want to allow http acces only for two LAN boxes; an only http access, which means that others protocols as smtp, pop3, imap and so on will be permited. The rest of LAN boxes will be redirected to a local http service (192.168.1.1:80) I think the best way is creating a iptables rules based on MAC address. So, the rules I've made are: iptables -t nat -A PREROUTING -p tcp -s 192.168.1.0/24 -m mac --mac-source ! xx:xx:xx:xx:xx:xx --dport 80 -j DNAT --to-destination 192.168.1.1:80 iptables -t nat -A PREROUTING -p tcp -s 192.168.1.0/24 -m mac --mac-source ! xx:xx:xx:xx:xx:xx --dport 80 -j DNAT --to-destination 192.168.1.1:80 Please, note the exclamation symbol, which means a logical negation. But it seems doesn't work correctly: all the LAN clients can suffer the web. ¿?¿?¿

xen and atl1
by Kamill S 25 Jun '07

25 Jun '07

Hello list, did someone have a similar issue like I have? -> Bought an AMD X2 3600+ and an Asus M2V (with Attansic L1 Gigabit Ethernet Adapter). Installed Centos 5 64_x86 and build atl1 from this source -> http://www.hogchain.net/attansic/AtL1Linux_v1.0.41.0.tar.gz After an insmod atl1 Centos say good bye with a kernel panic. I could only remind that there stand "Bad RIP value." and "_stext...." The driver runs fine with a non-xen kernel. Sorry for my scanty description. Its only a general question. Do someone have some informations? With google I don't have success. My next step is mailing to xen mailinglist. Thanks!
