The SRPM from ELRepo.org does not depend on xen or PAE kernels, but it does require xen and PAE kernel-devel packages installed *if* you build it for those variants. Equally you can just build it against a base kernel (non-xen/PAE) with the command line option --define 'kvariants ""'. Alternatively, if you don't like the elrepo SRPM feel free to grab the source code directly from the latest upstream kernel (http://kernel.org) and backport the code for yourself.

[CentOS] sed (or other) magic to get RPM base names ?
Hey folks, Once upon a time I saw some sed magic to take the output of "rpm -qa" and strip away all the version info to give just the RPM base names.

[CentOS] Xnest unable to connect with firewall enabled
Hi all, I have worked on both CentOS 5.2 and CentOS 5.3. In CentOS 5.2, I could connect to a remote X-server using Xnest binary provided by the package xorg-x11-server-Xnest-1.1.1-48.41.el5 with firewall settings enabled. I enabled the firewall settings from system-config-securitylevel. Now in CentOS 5.3 with firewall settings enabled, I am unable to connect to the remote X-server using Xnest (xorg-x11-server-Xnest-1.1.1-48.52.el5). To successfully connect, I have to either disable firewall settings or filter the TCP ports on which Xnest connects to the remote server. Is there an issue regarding firewall settings in CentOS 5.3 ? I want to connect to the remote X-server without disabling the firewall settings. How is possible ? Thanks in advance.

I don't know how it picks a PV, maybe flips a coin, but it isn't suppose to be a concern to the admin. One can explicitly assign a PV during LV creation by specifying the PV behind the VG name. If you want to stripe the PVs look at the -i and - I options to lvcreate. If you have a lot of PVs you can specify which PVs to stripe across by listing them after the VG name. -Ross ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

This does not exactly explain how it picks them at creation, but you can use the command "lvdisplay -m" or "lvdisplay -m /dev/vgname/lvname" to show which logical blocks are mapped to which physical blocks of the underlying pv.

I also have this configured in a couple of servers. as long as you have a wildcard certificate (*.example.com) and all names are direct subdomains of that domain (www.example.com, secure.example.com, intranet.example.com, wiki.example.com, bugs.example.com, etc.) it works just fine. There are some warnings in Apache's error_log, like those: [warn] Init: You should not use name-based virtual hosts in conjunction with SSL!! [warn] RSA server certificate CommonName (CN) `*.example.com' does NOT match server name!? But it works regardless of those. > Any way you can copy/paste your Apache configuration? There is nothing to it, you should only make sure that the SSLCertificateFile, SSLCertificateKeyFile and SSLCertificateChainFile point to the same files in all your virtual hosts, and that those files are the ones for the wildcard certificate. If you have to provide SSL for different domains, you can do that using IP-based virtual hosts, there is some documentation on how to do that here: http://httpd.apache.org/docs/2.2/vhosts/ip-based.html If you go that route and start having to assign a very large number of IPs to a single machine, you can assign a whole IP range to a machine by creating an interface alias to the loopback interface, that way you can assign 16, 32, 64, 128, 256 or even more IPs to a machine with one configuration only. Let me know if you would like more information on how to do that. Cheers, Filipe ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] redirect
Hi,
I have an Nginx http proxy server with SSL. What I want to do is:
If a client that has a certificate is trying to access the server's
address, he is to be redirected to our production server, to certain URL.
If a client doesn't have a certificate, he is to be redirected to the
same production server, but a different URL.
The problem is that if the client doesn't have a certificate, he gets
the following error:
400 Bad Request
The SSL certificate error
nginx/0.6.39
I've tried the following:
server {
listen 8443;
ssl on;
ssl_certificate /etc/httpd/ssl/proxy-ssl.cer;
ssl_certificate_key /etc/httpd/ssl/server.key;
ssl_client_certificate /etc/httpd/ssl/ca-bundle.crt;
ssl_verify_client on
.
.
error_page 400 /400.html;
location = /400.html {
root /usr/share/nginx/html;
but the error page 400 statement is simply ignored. Does anyone have an
idea how can I do it ? I tried to find the 400 error page, thinking
maybe I can make the redirect there, but it is simply not to be found.
P.S. my programming/scripting skills aren't any.

If it's a minor amount of processing, you can just pipe it to a script from procmail or even straight from the MTA.

[CentOS] Question about iostat output
Hello, We are planning to moving most of our servers to ESX but before buying our SAN, we want to do some I/O stats to see if iSCSI is enough or if we have to go with FC. So I found a plugin for Nagios that can log I/O stats with iostat. So far it's fine with single disk/one partition servers, but on our Oracle Database 10g server, we have two drives in RAID 1 (/dev/sda) and 4 other drives in RAID 10 (/dev/sdb). When I query iostat, I get : [r...@golgoth ~]# iostat Linux 2.6.9-55.ELsmp (golgoth.acaiq-ctb.lan)09/21/2009 avg-cpu: %user %nice%sys %iowait %idle 1.830.003.040.79 94.34 Device:tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn sda 8.4412.2532.40 489731534 1295151278 sda1 0.00 0.00 0.00 21360 7478 sda2 6.6080.9044.41 3234128950 1775185432 sda3 0.05 0.20 0.2378522129358056 sda4 0.00 0.00 0.00 2 0 sda5 41.1638.5995.20 1542695170 3805566528 sdb 2.8472.6328.91 2903208392 1155519494 sdb1 3.6777.1423.90 3083762026 955474128 sdb2 1.62 102.92 5.00 4114412086 200045262 So why sda have a lower TPS and bytes read/write than one of it's partitions (sda5, which is the root partition)?

However, that is strange, considering the previous command "groupadd -f -r avahi-autoipd" is trying to create that group, and the "-f" should make it fail (and abort the script) if it cannot create the group... Does the group exist on your system? What does "grep avahi-autoipd /etc/group" return? What does "getent group avahi-autoipd" return? What happens if you execute "/usr/sbin/groupadd -f -r avahi-autoipd" as root on the machine? Does the RPM install successfully after running that command?

[CentOS] Clarify TTY and virtual consoles
Hi, I need some help to clarify TTY and virtual consoles. Thanks a lot. 1. I learned that to switch from one TTY to another, one must be at the physical machine. Does the same apply to virtual consoles? 2. My /etc/inittab includes the following. Does that mean there's only one instance of TTY on my CentOS? ... # Run gettys in standard runlevels co:2345:respawn:/sbin/agetty xvc0 9600 vt100-nav #1:2345:respawn:/sbin/mingetty tty1 #2:2345:respawn:/sbin/mingetty tty2 #3:2345:respawn:/sbin/mingetty tty3 #4:2345:respawn:/sbin/mingetty tty4 #5:2345:respawn:/sbin/mingetty tty5 #6:2345:respawn:/sbin/mingetty tty6 3. My CentOS was installed with Base option only. (This should be the minimum.) I don't plan to use any GUI stuff, and I always connect to my CentOS server using SSH. In this case, do I still need virtual consoles and TTYs defined in /etc/securetty? 4. What does "console" mean in /etc/securetty? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Xnest unable to connect with firewall enabled (possible bug with 5.3)
Hi, My requirement is to use Xnest only. It was working seamlessly with 5.2 but not with 5.3 I am using this command to connect to the remote X-server. Xnest :1 -geometry 800x600 -query ** Can anyone confirm the same behavior? Or shall I file the bug in bugzilla?
