Default Firewall Entries
by Mickael Maddison 13 Apr '05

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. Anyone know what these are for, and if they should be disabled? -- Best regards, Mickael mailto:mike@kamloopsbc.com

Constant disk activity
by first last 13 Apr '05

13 Apr '05

Hi, I am running centos on a laptop and the HD keeps on making noises every so often, even when I go to runlevel 1 and stop everything that could be doing so (hotplug, smartd, cron, anacron, atd, syslogd...). 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. Thanks Gabriel Send instant messages to your online friends http://uk.messenger.yahoo.com

RE: [CentOS] Centos-4 Kernel pannic
by Bob Pierce 13 Apr '05

I think we might be interested in trying that new kernel. I will be upgrading the Server BIOS and SCSI RAID Firmware this morning, then we'll wait and see. If that doesn't help I think are next steps will be a new kernel and a memory scan. Thanks for your help, Bob. -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Johnny Hughes Sent: Wednesday, April 13, 2005 7:18 AM To: CentOS ML Subject: Re: [CentOS] Centos-4 Kernel pannic On Wed, 2005-04-13 at 07:47 -0400, James Olin Oden wrote: > This is not necessarily a problem with your hardware but could be a > bonified bug in the megaraid device driver. Looking at the changelog for the new kernel (from 2.6.9-5.0.3.EL up to 2.6.9-6.37.EL), there are several megaraid and/or scsi device driver changes ... may be fixed w/the new kernel.

Centos-4 Kernel pannic
by Bob Pierce 13 Apr '05

13 Apr '05

Hi all, We are running a new Centos-4 server, and it has kernel panicked on us 4 times in the last month. After the first kernel panic we hooked up a serial console to the server and captured the output in order to have a record of what happens. I've included the error messages from the last time it locked up... but it doesn't really mean much to me. Anybody have any ideas what might be causing this server lock up? Server description: -Dell PE1750 - dual 2.8Ghz Xeon (with Hyper Threading on) - 2GB DDR RAM - Perc4-DI onboard RAID using 3 scsi drives in raid-5 configuration -ext3 file system -kernel-smp-2.6.9-5.0.3.EL -mysql - from distribution -2 postfix instances rebuilt with MySQL support -amavisd-new -clamav -spamassassin -rbldnsd -bind Here's the captured output from a serial console connected to the server at time of fault.
