how to run a command on a specific vnc display
by Roland RoLaNd 09 Dec '10

09 Dec '10

Hello, I'm using selenium rc for automated testing on a centos box. working on the box itself has no problem as long as i start the server through terminal. though if i wanted to run tests remotely i have a problem with firefox not knowing on which display to run. i have a vnc client running on port 1 (5801/5901) I've tried the following: export DISPLAY=1 ; java -jar selenium-server.jar > /opt/selenium/Logs/logs.txt # through ssh session though that didn't work the only way to initiate it properly is to connect through vnc, open a terminal and type : java -jar $PWD/selenium-server.jar though i don't know how to automate this. so i thought of setting this in xstartup # vnc's startup for display 1 as such: 1 #!/bin/sh 2 3 # Uncomment the following two lines for normal desktop: 4 unset SESSION_MANAGER 5 exec /etc/X11/xinit/xinitrc 6 while true ;do sh /opt/scripts/rc; done & 7 [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup 8 [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources 9 xsetroot -solid grey 10 vncconfig -iconic & 11 xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & 12 twm & ]# more /opt/scripts/rc java -jar /opt/selenium/selenium-server.jar > /opt/selenium/Logs/logs.txt Though that isn't working either, and still the firefox profile doesnt know where to start. this is the error : PHPUnit_Framework_Exception: Response from Selenium RC server for getNewBrowserSession(*firefox, http://www.test.com) Failed to start new browser session: Error while launching browser. any help to automate the startup on display 1 would be greatly appreciated

dhcp + static dns
by aurfalien＠gmail.com 09 Dec '10

09 Dec '10

Hi all, Not having issues setting this in Ubuntu or Windows but I cannot seem to add a static DNS or search path without it getting over written when networks restarts. The file dhclient.conf seems ignored. I would like to simply have a fixed DNS and search path added to what ever was found by the dhcp client. So I don't think peersdns=no is an option. Any advice is greatly appreciated. - aurf

apache ssl config
by Steve Campbell 08 Dec '10

08 Dec '10

I hadn't noticed until just now that the default apache config file doesn't show a virtual host for https anymore. Does that have any significance, and do the same old config parameters apply to the new httpd when I want to set up a secure web site? Steve Campbell

copy old CF image to new CF device
by Jerry Geis 08 Dec '10

08 Dec '10

I am using an 8G CF card. (I was using dd to duplicate the card with different size cards I was advised not to). So I wrote the script below which basically: 1) runs fdisk to setup the device 2) makes the ext3 file system and the swap 3) mounts my old image "/" filesystem and the new partition 4) tar and untar the directories 5) run grub on it 6) set label for "/" After I run all the above I get: EXT3-fs error ext3_find_entry reading directory #129586 offset 0 then a couple lines later it remounts the root file system read only. What have I missed in successfully make the CF card based on the old image?

by Agnello George 08 Dec '10

08 Dec '10

HI I was just assigned a laptop with a pre install windows 7 in it. I decide to dual boot this server with cent os 5.5 , i did a "linux text " at the boot prompt as anaconda was not able to display the graphis screen ( it was barely viable ) . The installation happened perfect , but when i start x windows " startx" or init3 , i can barely see the display. I dont know where the issue lies , what module do i need to load .The display is barely visible . Thanks for all the help !! -- Regards Agnello D'souza

Problem with centos nfsroot
by me,apporc 08 Dec '10

08 Dec '10

I made a diskless node centos. the pxelinux.cfg/default file : default centos label centos kernel vmlinuz-2.6.18-194.el5 append initrd=initrd-2.6.18-194.el5.nfs.img nfsroot=10.10.10.1:/srv/centos ip=dhcp rw I can successfull*y boot-strap the system with no error.* *But when i shutdown or reboot it . It will show in the screen :* *Unmounting NFS filesystems* *INIT:no more process left in this rulevel* * * * * *and then ,it just hang.* * * *i think it is because it umounted the nfsroot filesystem and can't do the things behind. but I really have no idea about how to resolve that.* *Any help is granted. thanks.*

LVM change disk
by muhammad panji 07 Dec '10

07 Dec '10

Dear all, I have a 4,1TB Logical volume consist of four disks with size of 2TB, 1TB, 1TB, and 500GB. The LV currently full. I plan to change the 1Tb disks and 500Gb disks. I plan to remove one 1TB disk or the 500GB so that I can replace it with 2TB disk. most LVM tutorial ask to use pvmove to move phisical extent to the new disk. The problem is that I have no SATA port left so that I can't move PE to the new disk. How to migrate the data safely so that I can replace the disk? Thank you in advance regards, -- ----- Muhammad Panji

A hint is just that, a hint. I might put a couple of letters and/or numbers in, to remind myself of what the password is, but then block out the rest, such as BuXXXX-019999 mark, pulling brown paper bag over head before admitting to having written a lot of COBOL back in the day....
