Tomcat Monitoring
by Sean Carolan 20 Jan '09

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!

Starting slapd: /bin/bash: /tmp/start-slapd.K12378: Permission denied
by Brett Wiesner 20 Jan '09

20 Jan '09

Hi, I'm running Centos 5, with openldap Version: 2.3.27 Release: 8.el5_2.4. When I run: $ sudo /etc/init.d/ldap start I get the following error: Starting slapd: /bin/bash: /tmp/start-slapd.l14891: Permission denied (obviously the temp file number changes every time). It appears to be a permission problem but I thought I did everything to set up the permissions correctly... Everything is owned by the ldap user: $ cd /etc/openldap/ $ ls -al total 40 drwxr-xr-x 4 ldap ldap 4096 Jan 16 18:07 . drwxr-xr-x 66 root root 4096 Jan 16 17:55 .. drwxr-xr-x 2 ldap ldap 4096 Jul 9 2008 cacerts -rw-r----- 1 ldap ldap 886 Jul 9 2008 DB_CONFIG.example -rw-r--r-- 1 ldap ldap 246 Jul 9 2008 ldap.conf drwxr-xr-x 3 ldap ldap 4096 Jan 16 17:40 schema -rw-r----- 1 ldap ldap 3456 Jan 16 18:07 slapd.conf -rw-r----- 1 ldap ldap 12288 Jan 16 18:07 .slapd.conf.swp $ sudo ls -al /var/lib/ldap/ total 572 drwx------ 2 ldap ldap 4096 Jan 16 17:41 . drwxr-xr-x 21 root root 4096 Jan 16 17:40 .. -rw-r--r-- 1 ldap ldap 2048 Jan 16 17:41 alock -rw------- 1 ldap ldap 24576 Jan 16 17:41 __db.001 -rw------- 1 ldap ldap 278528 Jan 16 17:41 __db.002 -rw------- 1 ldap ldap 270336 Jan 16 17:41 __db.003 -rw------- 1 ldap ldap 98304 Jan 16 17:41 __db.004 -rw------- 1 ldap ldap 352256 Jan 16 17:41 __db.005 -rw------- 1 ldap ldap 24576 Jan 16 17:41 __db.006 -rw------- 1 ldap ldap 10485760 Jan 16 17:41 log.0000000001 When I run slaptest, it doesn't look great, but it doesn't look like a problem... $ sudo /usr/sbin/slaptest bdb_db_open: Warning - No DB_CONFIG file found in directory /var/lib/ldap: (2) Expect poor performance for suffix dc=XXXX,dc=net. bdb_db_open: db_open(/var/lib/ldap/id2entry.bdb) failed: No such file or directory (2) bdb(dc=XXXX,dc=net): Unknown locker ID: 0 backend_startup_one: bi_db_open failed!

prettyprint problem in CentOS 5.2
by tbuchanan＠vinu.edu 19 Jan '09

19 Jan '09

I'd like to ask for help with a problem in CentOS 5.2 when printing from the command line with the prettyprint option selected. Program students print out their code with the command: lpr -P<printer_name> -o prettyprint -o job-sheets=none <filename_to_be_printed> The prettyprint option, as you know, puts a banner with file name and date at the top, and uses a small font, and (for a color printer) uses different colors for different parts of the file. This last worked with a fully updated CentOS 4.7 server but after a move to a different fully updated CentOS 5.2 server the prettyprint option does nothing unless the first line of the file to be printed contains /*hello*/, (discovered quite by accident). CUPS on CentOS 4.7 was cups-1.1.22-0.rc1.9.27.el4_7.1 while the version on CentOS 5.2 is cups-1.2.4-11.18.el5_2.3. I tried printing from a couple other Linux distros, Fedora 10 (cups-1.3.9-6.fc10.i386) and Ubuntu 8.04 LTS, both of which were fully updated. The Fedora 10 exhibited the same problem while the Ubuntu 8.04 LTS printed properly with the prettyprint option. Is this a bug with the way RedHat implements CUPS or am I missing something? The only thing I found in a quick Google search that was similar (but with opposite effects, if I understand correctly) was this CUPS bug report http://www.cups.org/str.php?L2158 which gives no resolution. For now the instruction is having the students print via a script he created which adds \*hello*\ to the first line of their code. Any help would be appreciated. Ted
