[CentOS-docs] wiki.centos.org logo behaviour
Im curious ? When I click on the logo in upper left corner on wiki.centos.org then I get to the wiki frontpage, not the www.centos.org page!?! This is a bit redundant IMHO, I already have the frontpage menu, but there is no way to navigate back to www from the wiki as I can see.

[CentOS] Dual-booting CentOS and WinXP
Hi all, You know how I asked about procedures to build a dual-boot system with CentOS and WinXP a while ago? Well, I I've begun with a test machine. What I had from start was a working CentOS 5.3 32b system. What I did was to just add another empty drive configured as slave and then boot from the Windows install cd. The most curious thing happened now, I get a blank screen after the Windows installer screen saying something about Setting up install procedure... just at the beginning. That is to say, this happens only if the hd with CentOS is connected to power. If I disconnect the power connector to the CentOS drive, the Windows installer happily goes on. Is this to be expected, that Windows won't install if it sees a hd with another OS as master?

Also the OP should look into thin provisioning software that may be available for his EMC array. In some situations this can eliminate the need for LVM. For me I still use LVM because it helps when detecting what paths to use with MPIO. I often create larger(1-2TB) volumes on the storage array and then create smaller logical volumes in LVM, then when I need to expand I just expand, no need for new LUNs. If your data access patterns don't involve large amounts of writes and then deletes(thin provisioning dedicates storage when it is written to), then you don't need volume management at all the array can do it for you. Most workloads in my experience are friendly with thin provisioning, some are not. Some vendors have ways to reclaim deleted space as well to put it back into the storage pool(s) for use by other systems. http://searchstorage.techtarget.com/news/column/0,294698,sid5_gci1134713,00.html nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Kickstart hang trying to install CentOS 5.3
I've been using kickstart successfully with a local mirror going back to CentOS 4.X. I'm trying to install CentOS 5.3 via kickstart on a new system (which happens to be different than most other systems I've installed on), and the install process always hangs shortly after the partitions are created. If I go to the alternate console #3, the last two lines are always this (except that the time stamp changes every time I try it of course): 10:06:18 DEBUG: Member xorg-x11-drv-i128-1.2.0-4 - u 10:06:18 DEBUG: Adding Package xorg-x11-drv-i128-1.2.0-4.i386 in mode u This is preceded by hundreds of similar lines for other packages, but it always hangs at xorg-x11-drv-i128-1.2.0-4. I am currently out of other systems to test/install this on. Instead of the usual ThinkCentre mini tower, this system is a ThinkCentre pizza box. I've installed CentOS on this type of hardware before without problems, but it hangs on the only two systems I currently have. It's possible that there is something wrong with my local mirror, but I rsync it every night and this problem has been going on for a few days. I will try to install this on a mini tower to rule out any hardware compatibility issues, but in the mean time, I'm looking for suggestions on how to debug this. I've booted into Linux rescue mode after power cycling the system after it hung to look at whatever did get installed, but there are no useful log files.

[CentOS] Dealing with brute force attacks
Over the weekend one of our servers at a remote location was hammered by an IP originating in mainland China. This attack was only noteworthy in that it attempted to connect to our pop3 service. We have long had an IP throttle on ssh connections to discourage this sort of thing. But I had not considered the possibility that other services were equally at risk. Researching this on the web does not reveal any comprehensive list of vulnerable ports or services. Most discussion centres on ssh, then some on ftp, and relatively few regarding pop3. So, my questions are these: 1. Should I throttle all new connections regardless of destination ports? In other words: are there any legitimate reasons that a single IP would require more than one new connection every 30 seconds or so? 2. Moving pass the obvious and unhelpful everything, what services are particularly vulnerable to these types of attacks? Does a list exist anywhere?

CentOS 5.x takes much longer to get to the point where it is installing packages than 4.x, probably a good 3-4 minutes more, perhaps longer if your mirror is over a WAN connection, my mirror is on the local LAN and it does take a long time as well though it always has(CentOS 5.0,5.1,5.2, haven't tried 5.3). Unless your waiting for hours for it to go I think what your seeing is normal. I'd suggest using a mirror on your local network to see if it speeds anything up, but I think most of the time is spent on the client calculating the various things it needs for packages. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Postfix: user unknown
Dear all,
I have a mail server based on a CentOS 5.3 machine with postfix.
Most of our users are on LDAP (on localhost) but we also have some local
users and we are using PAM for authentication.
Are you running nscd on the server? That should smooth out LDAP
blips, though I would disable nscd's dns caching in /etc/nscd.conf
Is postfix configured to talk directly to LDAP ? What does the
configuration look like?

We are using nscd with the default configuration.
This server also has a web server, will disabling nscd's dns cache have
negative impact on the performance in this service (or others)?

If that is the case, am I going to be downloading the .iso images during the install, or is there a directory at that or some other location that contains the packages needed for the installation to proceed? I think I see what you're asking. If you start out at http://isoredirect.centos.org/centos/5.3/isos/ i386/ and choose a mirror (say, http://mirrors.bluehost.com/centos/5.3/isos/i386/) you'll be presented with a list of the ISOs for CentOS. What the netinstall is looking for is a few directories back and down from this location. By clicking on Parent Directory two times and drilling down into os/ i386, THIS is directory path that you want to enter into the netinstall part of the CentOS installer. From the example mirror above, the first line would be... mirrors.bluehost.com and the second line would be... centos/5.3os/i386 The installer goes into the images directory and downloads stage2.img to continue with the net-based installation.

Re: [CentOS] Kickstart hang trying to install CentOS 5.3
How long does it hang? CentOS 5.x takes much longer to get to the point where it is installing packages than 4.x, probably a good 3-4 minutes more, perhaps longer if your mirror is over a WAN connection, my mirror is on the local LAN and it does take a long time as well though it always has(CentOS 5.0,5.1,5.2, haven't tried 5.3). I waited overnight and it was still hung in the morning. My local mirror is on the LAN, so it's not a network issue. I was able to find another system, and it appeared to hang at the same spot (that is, I was looking at alternate console #3 and saw that it stopped at the same RPM). However, after a couple of minutes it proceeded. My guess is that this RPM is the last one to download, and the kickstart process needs to think about the next step. While it was stuck at this step, anaconda was using close to 100% of the CPU according to top in console 2. So it appears to be a resource problem on the smaller desktops. The specs are Pentium 4 @ 3.00GHz with 1.5GB of memory and integrated Intel 915G/915GV/910GL accelerated VGA graphics. This should be more than enough to install/run CentOS. I even tried installing in text mode and it also hung. Very strange... Alfred ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Preventing hour-long fsck on ext3-filesystem
Hi! I'm justing in the process of setting up a new fileserver for our company. I'm installing CentOS 5.3 (64 bit) on it. One of the problems with it is that it has a 3.5TB filesystem for the user data which I formatted during setup as an ext3. Now my experience with our current fileserver is that a 0.5TB ext3 filesystem needs approx half an hour to complete (and kicks in every so and so reboots or every 180days). My estimate is that for the larger filesystem (and the faster machine) the fsck would need well over an hour (being optimistic). I dread the day when I have to reboot the server and wait for 2hours or more just because the system thought it would be a prudent thing to check the filesystem. My question: - is there another stable filesystem (XFS, ReiserFS ...) in the centosplus-kernel where this could be avoided (fsck is faster) and that is as safe as ext3 - Or would it be better to switch off automatic checking with tune2fs Any opinion/experience welcome.

This attack was only noteworthy in that it attempted to connect to our pop3 service. We have long had an IP throttle on ssh connections to discourage this sort of thing. But I had not considered the possibility that other services were equally at risk. Researching this on the web does not reveal any comprehensive list of vulnerable ports or services. Most discussion centres on ssh, then some on ftp, and relatively few regarding pop3. So, my questions are these: 1. Should I throttle all new connections regardless of destination ports? In other words: are there any legitimate reasons that a single IP would require more than one new connection every 30 seconds or so? 2. Moving pass the obvious and unhelpful everything, what services are particularly vulnerable to these types of attacks? Does a list exist anywhere? Regards, Hi - I went though a similar process back when the DNS cache poisoning attacks were coming fast and furious. The question to answer is, Are there legitimate reasons why the same IP address will apparently make multiple connection requests for a particular service? For DNS the answer was a resounding no since the source nameserver should cache the results of the query. For POP3 the answer is more dependent on your particular organization. As an example, is there a remote office that will generate a number of connection requests when everyone egts to work in the morning; all apparently from the same IP address? If there are no such legit reasons why a number of requests could occur in a short period of time, a simple firewall throttling rule may be sufficient. I have an article on my blog describing the firewall rules I used to throttle and then block DNS cache poisoning attacks at: http://davenjudy.org/davesBlog/node/41 One of the other replies also suggested fail2ban which may be more appropriate anyway since you really want to look at failed logins; not just connection attempts.

Probably not a default, but an option. Is this a reasonable choice on a 32 bit machine? I thought 4k stacks were a problem. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Oh yeah, I failed to mention in my previous e-mail that all the machines I have running XFS are using x86_64 versions of CentOS. I don't know if the 4k stack on 32-bit machines is still an issue. In any case, nowadays I would recommend x86_64 for servers anyway, even if they have only 2GB of RAM. It works much better than PAE, etc., for 4GB RAM or more, and even if you still have less than 4GB RAM installing x86_64 will make it much easier when you want to upgrade.

Re: [CentOS] Kickstart hang trying to install CentOS 5.3
Alfred von Campe wrote: I waited overnight and it was still hung in the morning. My local mirror is on the LAN, so it's not a network issue. hmm, is your package selection particularly complex? In my case I list hundreds of packages in my %packages section I don't have groups and stuff. I assume your using a stock CentOS install and you didn't put any of your own 3rd party rpms in the installation and update the comps.xml(?) file to include them? A P4 3Ghz is plenty to install CentOS, I install CentOS 5.2 at least on 2Ghz systems with 1GB or less ram(running in VMs), I do get about a 2-4 minute pause but nothing as severe as what you see. I'm not sure what to suggest..if your packages selection is complex try simplifying it. I believe what is going on during that stage is it's calculating all of the dependencies and stuff. I don't expect strace to be installed as part of the stage2 installer if it were it'd be interesting to know what exactly it's doing.. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
