Support Tools
by Thorsten Kampe 16 Feb '08

16 Feb '08

Hi, does something like the SUSE/Novell ntsutils (previously called "supportconfig") or Microsoft's MPS Reports exist for CentOS or Red Hat Enterprise Linux? I mean a program that reads and exports various configurations and parameters to facilitate technical support. Thorsten

New kernel (2.6.18-53.1.13) generates "unknown attribute" errors during boot
by MHR 16 Feb '08

16 Feb '08

I've seen this now a few times, but of course I didn't write them down, so I may have the wording a little off. The new kernel seems to contain something in udevd that is now generating a whole slew of unknown attribute(or something like that) errors during the boot, before the part where dmesg picks up. They don't seem to be causing any actual problems while the system is up and running, but.... Anyone know anything about this (and what)? Curious. mhr

problems with iscsiadm
by Maysara A. Abdulhaq 16 Feb '08

16 Feb '08

Hello, I'm fairly new to centos and to iscsi, I have installed a fresh copy of centos (CentOS release 5 (Final)) and installed iscsi-initator-utils, iscsiadm -V shows iscsiadm version 2.0-865 . when i try to connect to iscsi target it doesnt work ... it just stays idle , i try something like: iscsiadm -m discovery -t st -p 172.20.2.76 show or with -m node .... --login ...etc, none works. using the same configuration on ubuntu gutsy, same version things work! i also made both /etc/iscsi/iscsid.conf identical ... no luck :( i did tcpdump too (-vv -n ) and then grep the ip of the iscsi target, i see no traffic to the iscsi target at all on the centos machine, i tried it on the other machine it works :S Is there anything else to check? firewalls are all shutdown on all nodes ... i tried switching ips too .. any hint is greatly valued, thank you -- Maysara A.

Hardened PHP? Suhosin patch?
by Niki Kovacs 16 Feb '08

16 Feb '08

Hi, I'm running a few PHP-based apps on our server (PMB, SPIP, Joomla, PHPMyAdmin), and I'm not always comforted about security. I don't know the details, but many a security expert frowns when it comes to PHP. Now I just stumbled over this: http://www.hardened-php.net/suhosin.127.html Has anyone already tried this out? An opinion about it? Is it worth it? Since I have to rebuild PHP anyway (because I need some specific modules that can only be obtained by rebuilding it), it wouldn't be much of a hassle. But I'm curious about the experts' opinion here. Cheers, Niki

system-config-display problem
by Anne Wilson 16 Feb '08

16 Feb '08

I bought a Viewsonic VG730m monitor, analogue and digital. With a digital cable connected the screen keeps blanking for a second or so. system-config-display shows it configured as a CRT monitor, and refuses to accept that it is an LCD monitor. I've tried manually editing xorg.conf, putting in the manufacturer's values for horizontal and vertical refresh, but the problem remains. The Viewsonic website has lots of information for windows and some for mac, but nothing for linux. I need either to find how to make system-config-display keep the setting I'm giving it or to know what entry to put into xorg.conf to make it understand that it is an LCD display. Sorry if this sounds naive, but I've not had a digital monitor before. I could go back to using the analogue connection, which gave no problems, but you'll understand that I'm reluctant to do that.

Boot CentOS using the install CD and type linux rescue. You can run the command there when / is unmounted. Don't mount the partitions if it asks you to.

Centos 5 and milter rpm's
by Tim Alberts 15 Feb '08

15 Feb '08

As I mentioned on this list before, I'm switching from Fedora 6 to Centos 5. I'm setting up the mail server and on Fedora I used the milter rpms for greylisting, spamassassin, mimedefant etc. However I don't see that those are included with Centos? Is this true, or do my yum repositories need to be changed to look in an 'extras' location? Or is there some other source for sendmail milter RPMS like on FC6?
