Re: [CentOS] followup to request for centos C/W
by fabien faye 20 Jan '10

20 Jan '10

I can confirm, after my last discussion with Redhat, is it better to learn KVM. Xen is going to die on redhat and centos in some years.

I agree. Since RH is moving to KVM, it is better to learn KVM if you have a choice.

centos courseware?
by Robert P. J. Day 20 Jan '10

20 Jan '10

does anyone here have pointers or access to courseware that could be used to teach centos (5.4, i believe)? publicly-available, free C/W would, of course, be ideal, but if you have some decent training manuals that you're willing to license on a per-manual basis, i'm still willing to chat. rday -- ======================================================================== Robert P.

followup to request for centos C/W
by Robert P. J. Day 20 Jan '10

20 Jan '10

just to follow on my earlier post, i have pointers to a couple commercial C/W manuals for RHEL administration, but both of them use an entire chapter discussing virtualization using Xen. i'm under the impression that RH is firmly in the KVM camp (at least for now), and that learning Xen on red hat/centos wouldn't be as useful as learning KVM. thoughts? rday -- ======================================================================== Robert P.

would anyone out there care to share their robots.txt experience using centos as a webserver and their robots.txt files? i realize this is a somewhat simple exercise, yet i am sure there are both large and small hosters out there and possibly those that have high traffic modify their robots.txt files differently that others ??? please share if you can or care to please? for years we have just did a * (allow all) and disallow on things like /cgi-bin as examples of places to visit for those out or in the know... http://www.robotstxt.org/ http://en.wikipedia.org/wiki/Robots_exclusion_standard http://www.google.com/robots.txt and others... quite frankly, there are many orgs out there that dont follow this anyways, right? anyone? tia - rh

How to force iscsi to see the new LUN size
by Peter Blajev 20 Jan '10

20 Jan '10

Hi, I increased the size of one of the LUNs and on CentOS 5.4 if I restart iscsi (`service iscsi restart`) I'll see the the new size but this will disconnect all other LUNs. I'm hoping that there is isciadm or some other command that will force iscsi to rediscover the LUNs but I can't seem to be able to come up with one. Resize2fs says that there is nothing to be done. I'm not using LVM. Any ideas? Thanks Peter

Moving the system from 5.3 to 5.4
by Renato Botelho 20 Jan '10

20 Jan '10

Hello, I built a system based on centos 5.3, now i'm planing to move to 5.4. To do it I rebuilt all rpms making some changes. When I use a common centos 5.3, it automatically detects that 5.4 is available and move update for it when i run yum update. How does this work? How the system detects new version and update for it? I thought centos-release rpm just update repo for it, but I saw this is not the case. Could someone gimme some light? Thanks -- Renato Botelho

iptables default configuration
by Carlos Santana 19 Jan '10

19 Jan '10

Hi, I would like to get some inputs on how to configure iptables. I have referred to CentOS wiki http://wiki.centos.org/HowTos/Network/IPTables and it has been very helpful. I have configured iptables with the help of this tutorial, but I haven't understood few things about default firewall config. - What does 'RH-Firewall-1-INPUT' chain means? This also seems to be a predefined chain, although not mentioned in wiki. - The wiki page approach is to flush existing rules and then add required rules to iptables. Is it possible to add/append required rules without flushing existing set of rules? Not sure, but I think this is where 'RH-Firewall-1-INPUT' chain comes into picture (user defined rules). Any explanation or resource link on this would be really helpful. Thanks, CS.
