Does anyone know if I can reconfigure a PERC H700 without rebooting?
by Kevin Thorpe 22 Aug '11

22 Aug '11

Hi all, I have a server which is really difficult to restart because of usage requirements and the fact that it's in a co-lo rack so miles away. I've added a couple of drives which I'd like to bring up and add to LVM but the config I know is in the PERC BIOS and requires a reboot. Can the config be changed in the openmanage suite and if so can someone point me in the right direction? thanks

Intel 82599 driver?
by Lars Hecking 22 Aug '11

22 Aug '11

Which version of the ixgbe driver is included in 5.6? I went through all the RHEL5 release notes, but they only ever state that the driver was updated, not which devices was added. This device is not supported up to CentOS 5.5 (2.0.44-k2), but the latest driver from the Intel web site works fine (3.2.10). 05:00.0 Ethernet controller: Intel Corporation Unknown device 151c (rev 01) 05:00.0 0200: 8086:151c (rev 01) Subsystem: 8086:a03c Flags: bus master, fast devsel, latency 0, IRQ 170 Memory at de400000 (64-bit, non-prefetchable) [size=2M] I/O ports at ecc0 [size=32] Memory at de3f8000 (64-bit, non-prefetchable) [size=16K] Expansion ROM at de200000 [disabled] [size=1M] Capabilities: [40] Power Management version 3 Capabilities: [50] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable- Capabilities: [70] MSI-X: Enable+ Mask- TabSize=64 Capabilities: [a0] Express Endpoint IRQ 0 Capabilities: [e0] Vital Product Data Capabilities: [100] Advanced Error Reporting Capabilities: [140] Device Serial Number 2c-cf-9a-ff-ff-21-1b-00 Capabilities: [150] Unknown (14) Capabilities: [160] Unknown (16)

Determine high i/o reads/write directories
by Robert Arkiletian 22 Aug '11

22 Aug '11

I have a DRBL server, basically an nfs fileserver, which I am rebuilding. I want to put the high i/o directories on a separate raid array for performance. Currently everything is under / in one raid array. How can I tell which directories, obviously other than /home, are getting high reads and/or writes? Any tools to measure i/o per directory? Thanks -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada

Apache Changing IPtables C 5.6 via Apache
by Always Learning 22 Aug '11

22 Aug '11

When a web site is attacked, so far by unsuccessful hackers, my error routine adds the attackers IP address, prefixed by 'deny', to that web site's .htaccess file. It works and the attacker, on second and subsequent attacks, gets a 403 error response. I want to extend the exclusion ability to every web site hosted on a server. My preferred method is iptables. However, when breaking-out of a PHP script on a web page and running a normal iptables command, for example: iptables -A 3temp -s 1.2.3.4 -j DROP iptables responds with: iptables v1.3.5: can't initialize iptables table `filter': Permission denied (you must be root) Executing 'whoami' confirms Apache is the user. Giving Apache group rw on the /etc/sysconfig/iptables and ensuring the /sbin/iptables is executable by all, fails to resolve the problem. Is there any method of running iptables from an Apache originated process ? Thank you. -- With best regards, Paul. England, EU.

by Always Learning 22 Aug '11

22 Aug '11

A new .xxx domain suffix for sexual content is becoming available. If you have a cherished Trade Mark or brand name and do not want relish having your_domain_name.xxx being available to Cyber Squatters or the 'porn trade' you can block the issuing of that .xxx domain name for a single payment of USD $200 - $300. The blocking application period is from 7 September 2011 until 28 October 2011. The details of where to apply were not disclosed. .xxx will cost about USD $75 yearly.

Multipath w/ iscsi
by Joseph L. Casale 22 Aug '11

22 Aug '11

I have several CentOS 6 boxes that mount iscsi based luns and use mpath. They all had problems shutting down as a result of unused maps not getting flushed as the system halted. After examining the init scripts, netfs, iscsi and multipathd all had the correct order but mpath failed to flush these maps and the system waited indefinitely. In the meantime I hacked this by adding a `/sbin/multipath -F` at the end of the stop clause in the init script. I seriously doubt this problems exists w/o being the result of my error in configuration. Anyone know what the required mpath config might be in this scenario where the block devices all disappear once netfs unmounts and iscsi stops? Thanks! jlc

help with gpg
by Jerry Geis 21 Aug '11

21 Aug '11

Under Centos 5 I ran this command: gpg --passphrase-file /home/myuser/pass_phrase.txt -c ../Versions/program.x86_64.tgz and this worked fine. On CentOS 6 running the same command prompts me for the passphrase. Thats exactly what I dont want to have happen. I have the pass phrase I want in the file. After some searching it says I need to start the daemon like "gpg-agent --daemon" take the output: GPG_AGENT_INFO=/tmp/gpg-x4WH7K/S.gpg-agent:19156:1; export GPG_AGENT_INFO; and use it - which I did. Then when I run my command above I still get prompted for the pass phrase. What am I not doing correct? I just want a simple phrase on a file that someone has to know before they can extract it. Nothing special going on.... Thanks, Jerry

Centos6 - Logwatch not mailing on 64bit
by david 21 Aug '11

21 Aug '11

Folks Logwatch is doing its thing properly on my 32-bit servers, delivering the report by mail to my root account once a day sometime around 3:30am. On the 64-bit systems, no mail is occurring. From the "cron" log on a 64-bit system, there are lines like: cron-20110821:Aug 21 03:36:23 XXX run-parts(/etc/cron.daily)[9727]: finished 0logwatch (where "XXX" stands for the server name) but no report is sent. If I run logtwatch manually, by simply typing logwatch as root, I get the mail. Is this a known issue? Is there some information I could supply that would help identify the reason? To the best of my knowledge, I made no changes to the logwatch configuration. Thanks David Kurn

Fedora and CentOS no longer on speaking terms
by Anne Wilson 20 Aug '11

20 Aug '11

I have just upgraded my server from CentOS 5 to CentOS 6 and am having connectivity problems. My laptop runs Fedora 14, and I have been in the habit of mounting data partitions on my server by fstab entries. Since the update I've not been able to do that. On watching the messages during a reboot I saw a statement that the connection was denied by the server (where are those messages stored so that I can quote accurately?). I have temporarily disabled both the firewall and selinux, and the problem persists, so clearly they are not the cause. Logwatch has the following section which may or may not be connected: --------------------- Connections (secure-log) Begin ------------------------ Userhelper executed applications: anne -> system-config-users as root: 1 Time(s) **Unmatched Entries** polkitd(authority=local): Operator of unix- session:/org/freedesktop/ConsoleKit/Session2 successfully authenticated as unix-user:root to gain TEMPORARY authorization for action org.fedoraproject.config.firewall.auth for system-bus-name::1.88 [/usr/bin/python /usr/bin/system-config-firewall] (owned by unix-user:anne): 1 Time(s) polkitd(authority=local): Registered Authentication Agent for session /org/freedesktop/ConsoleKit/Session1 (system bus name :1.24 [/usr/libexec/polkit-gnome-authentication-agent-1], object path /org/gnome/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8): 1 Time(s) polkitd(authority=local): Registered Authentication Agent for session /org/freedesktop/ConsoleKit/Session2 (system bus name :1.45 [/usr/libexec/polkit-gnome-authentication-agent-1], object path /org/gnome/PolicyKit1/AuthenticationAgent, locale en_GB.utf8): 1 Time(s) polkitd(authority=local): Unregistered Authentication Agent for session /org/freedesktop/ConsoleKit/Session1 (system bus name :1.24, object path /org/gnome/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus): 1 Time(s) polkitd(authority=local): Unregistered Authentication Agent for session /org/freedesktop/ConsoleKit/Session6 (system bus name :1.214, object path /org/gnome/PolicyKit1/AuthenticationAgent, locale en_GB.utf8) (disconnected from bus): 1 Time(s) ---------------------- Connections (secure-log) End ------------------------- An example fstab line is /Data1 /nfs4exports/Data1 none bind 0 0 Under CentOS 5 this was mounted by the exports line: /nfs4exports/Data1 192.168.0.0/24(rw,insecure,no_subtree_check,nohide) Following advice, I have changed this to: /Data1/ 192.168.0.0/255.255.255.0 *(rw,sync,insecure,no_all_squash) That hasn't helped at all. I'm completely at a loss, and really need to get this connection working again. I've done lots of googling and reading, but just feel to be digging an ever-deeper hole. All help appreciated. Anne
