Antw: [CentOS] CentOS and HP Drivers
by Arthur MEßNER 14 Apr '05

14 Apr '05

We are using the Hp-Agents continuously on our Servers. The latest Version with centos-3.3 was no Problem. Mainly it depends on the used kernel Versions, because the raid driver modules are not for vanilla kernels, only for official Kernels from Redhat, Suse ... The only thing you have to do, is to fake the /etc/redhat-release, because the installer looks for supported Linux Versions. After Installation you can view your Configuration via firefox. http://localhost:2301 also you will see alot new processes starting. ------------------------------------------------------------- Ing.

Re: [CentOS] Constant disk activity
by Ron Yorston 14 Apr '05

14 Apr '05

>Is there any way of finding out what is accessing the disk? Not only it >shortens battery life, it is annoying while working in a quiet room. When I had problems with irritating disk noises on a laptop it turned out that the problem wasn't so much disk access as an over-aggressive power management setting. hdparm -I /dev/hda | grep 'power management' should tell you the current setting. The default value seems to be 128, but what exactly that means depends on your hard disk. I found that changing the setting to 200 was a big improvement: hdparm -B 200 /dev/hda You can make the change permanent by editing /etc/sysconfig/harddisks. Ron

Re: [Centos] rpm corruption
by John Newbigin 14 Apr '05

14 Apr '05

In answer to my own question, this is what I have done which appears to fix the problem: 1. Edit /usr/lib/rpm/macros and change the line %__dbi_rebuild nofsync !log !txn !cdb to %__dbi_rebuild nofsync !log !txn !cdb !thread 2. export LD_ASSUME_KERNEL=2.2.5 3. rpm --rebuilddb 4. unset LD_ASSUME_KERNEL 5. Edit /usr/lib/rpm/macros back to the original 6. rpm --rebuilddb So far this fixes the problems I have been having. I assume it is possible to override the macro setting on the rpm command line so no editing is required and a simple script can be run on all my machines. John.

swiotlb causing panics on 8gig ia32e systems running Centos 3.4 x86_64
by James Olin Oden 14 Apr '05

14 Apr '05

Hi All, I have several ia32e systems with 8 gig that panic on install and first boot. The panic is arch/x86_64/swiotlb.c (working from memory so I might be a bit off) and its in the routine that I think is trying to allocate another chunk of memory for the "Software I/O Translation Buffer". I am guessing it needs to allocate contiguous chunks of memory and that is why it fails on the realloc. Anyway, on install the only way I can get the install to work is to set "mem=512" or something way below 8Gig. Whereas once the machine is loaded I can get it to boot by without a panic by passing the kernel arg swiotlb set to some rather larger value like 16384. Doing this with varying values during install yields either the same panic or causes a failure of the kernel to detect the cdrom device due to some "resource conflict", which why on a hunch a fellow engineer tried the mem option. Anyway, we can live with this work around if we have to, but I was wondering a couple of things: - Is there any metric to choose a proper value for ioswtbl? - Since its failing to do the re-alloc in the boot kernel am I likely to see this occur on the installed kernel at some inopportune moment? - If there is such a metric does anyone have any ideas on how it might could be grafted into the kernel itself in such a way that all interested parties would be OK with such a patch? And of course if anyone else has seen this, I would be interested in their knowledge on the issue. Just so you know I familiar with this enough to know that ia32e (nocona/lindhurst 64 bit one off copy of AMD 64 bit processors) does not contain an IOMMU (unlike the AMD processor) and thus the kernel developers had to do a serious hack creating this bounce buffer like thing. Which is all to say I understand why its there, and that on the ia32e systems I have to live with it, I just want it to be stable or find some way to make it so. Thanks...james

multiple external addresses on one interface
by ryanag＠zoominternet.net 14 Apr '05

14 Apr '05

I want to add two IP ranges on one NIC card (eth0 and eth0:1). Has anyone done this before? The CentOS 4 gui keeps locking up when I try it there and the command line ifconfig seems to work, but ifup always returns the error that is never heard (no such device) of eth0:1 thanks

Default Firewall Entries
by Mickael Maddison 13 Apr '05

Hello CentOS, I'm curious... there seems to be a couple of default firewall rules that I'm not familiar with in the CentOS 4.0 # Firewall configuration written by system-config-securitylevel # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :RH-Firewall-1-INPUT - [0:0] -A INPUT -j RH-Firewall-1-INPUT -A FORWARD -j RH-Firewall-1-INPUT -A RH-Firewall-1-INPUT -i lo -j ACCEPT -A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT -A RH-Firewall-1-INPUT -p 50 -j ACCEPT -A RH-Firewall-1-INPUT -p 51 -j ACCEPT -A RH-Firewall-1-INPUT -p udp --dport 5353 -d 224.0.0.251 -j ACCEPT -A RH-Firewall-1-INPUT -p udp -m udp --dport 631 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT -A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited COMMIT Particularly, the 5353 udp allowing from 224.0.0.251 and the 631 udp.
