combining kickstart and DVD on a USB thumbdrive
by Jerry Geis 21 Jan '09

21 Jan '09

Hi all, I am trying to find information on taking a DVD of centos 5.2 x86_64 and putting it AND my kickstart file on a USB8G thumbdrive. Note - I am not INSTALLING linux on the USB disk just trying to make installation media for it. I am not taking just the bootdisk.img file to make the USB bootable but the entire DVD content on the USB and my kickstart files. I'd like to just be able to plug in a USB disk that I have made that has all the kickstart information and the machine is just setup based on WHICHEVER usb thumbdrive in place in the machine. Is there something out there that explains this that I have not found? Thanks for any pointers. Jerry

SquirrelMail Oddity SSL error
by John Hinton 20 Jan '09

20 Jan '09

I have two users only under one virtual domain which after sending an email are returned to a screen which says: Secure Connection Failed An error occurred during a connection to replacedrealdomainnamehere.org:80. SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long) The page you are trying to view can not be shown because the authenticity of the received data could not be verified. * Please contact the web site owners to inform them of this problem. First, this seems to be happening only with two users under one domain on the server. SSL for SquirrelMail is not enabled. I can't find a thing unique to these two users which would cause this error. I can't find anything in the logs to help. Has anybody else seen anything like this and perhaps have a cure? John Hinton

Tomcat Monitoring
by Sean Carolan 20 Jan '09

What do you use for monitoring your Apache Tomcat servers? I have used jconsole to manually connect and look at the statistics. I'm wondering if there are any standard tools for watching the health of the java process.

Generating password string in /var/nis/passwd with Perl
by Alexander Farber 20 Jan '09

20 Jan '09

Hello, in our network we have AD (Win 2003) for user authentication under Windows and NIS (CentOS 5.2) for same under Linux: # rpm -qf /var/yp filesystem-2.4.0-1.el5.centos ypbind-1.19-8.el5 yp-tools-2.9-0.1 ypserv-2.19-3 I have written a CGI Script to add new users both to AD and NIS and also to create the home dirs at our NetApp-Filer. Unfortunately some steps still have to be made by hand (the sysadmin copy-pastes it from a browser to a shell). I could skip one manual step (calling yppasswd) if I knew how to generate the passwd string for /var/nis/passwd: farber:oav3dV4.Mnj/.:10154153:5725:Alexander Farber,jn-05/02,,,,:/home/farber:/bin/bash Has anybody already figured out, how to do it from Perl? I'm sure there must be some way (smth. with Perl's crypt). Regards Alex PS: Here is my script: http://pastebin.com/m46057a70 feel free to modify and use

by Rainer Traut 20 Jan '09

20 Jan '09

Hi, Sys: C5.2, X86_64 my plan is to automatically mount five same brand usb disks in five different directories. I have written the following udev rule; Problem is, it does not mount them on boot, only when I plug them in. KERNEL=="sd*", SYSFS{serial}=="57442D574341554830303133323337", SYSFS{product}=="My Book", SYMLINK+="usbdisc0", ACTION=="add", RUN+="/bin/mount -o noatime /dev/usbdisc0 /mnt/woche1" KERNEL=="sd*", SYSFS{serial}=="57442D574341554631383831303534", SYSFS{product}=="My Book", SYMLINK+="usbdisc1", ACTION=="add", RUN+="/bin/mount -o noatime /dev/usbdisc1 /mnt/woche2" KERNEL=="sd*", SYSFS{serial}=="57442D574341554631383831343136", SYSFS{product}=="My Book", SYMLINK+="usbdisc2", ACTION=="add", RUN+="/bin/mount -o noatime /dev/usbdisc2 /mnt/woche3" KERNEL=="sd*", SYSFS{serial}=="57442D574341554631383831303930", SYSFS{product}=="My Book", SYMLINK+="usbdisc3", ACTION=="add", RUN+="/bin/mount -o noatime /dev/usbdisc3 /mnt/woche4" KERNEL=="sd*", SYSFS{serial}=="57442D574341554B30303239303435", SYSFS{product}=="My Book", SYMLINK+="usbdisc4", ACTION=="add", RUN+="/bin/mount -o noatime /dev/usbdisc4 /mnt/woche5" How can I make them mount on boot? Thx Rainer

Help with a good recovery plan.. Linux rescue?
by Glenn 20 Jan '09

20 Jan '09

Hello All, I have a machine that crashed. Some part of the motherboard (power supply-related) went south. The motherboard, CPU and memory have been replaced with a much newer architecture. The OS and data are intact on two SATA drives that were RAID1 with LVM. I am going to use 'linux rescue' to recover the LVM backup so I can mount the RAIDs (there were two) in a new CentOS install, on a third disk. I have no indication that I could recover the previous CentOS (somewhere between CentOS 5.1 and 5.2 on updates). Can I use 'linux rescue' to fix that OS up to boot it? The kernel panics in its current state (because the hardware architecture is so strikingly different). What is the methodology of fixing the kernel in this circumstance? Thanks in Advance! Glenn

(OT) Firewall Question
by Jun Salen 20 Jan '09

20 Jan '09

Hi List, I am not familiar with the commands of IPtables so I want use tools on top of it. What do you suggest. Can I make test of it inside CentOS on top of VMWare server with only one LAN inteface? I try to use Pfsense, I believe it has easy to understand GUI but it fails to install on my desktop machine to test, maybe due to hardware comaptibility. Kernel panic during boot even after disabling ACPI. If you have suggestion on tools or template for Iptables to suggest or share, please do. Thank you very much. junji aisalen.wordpress.com Linux Registered User #253162 CentOS User Get your new Email address!
