ssh-askpass in bash script
by Tim Dunphy 03 Mar '14

03 Mar '14

Hey all, I have ssh-askpass installed on Centos 5.7 and I'm trying to find a way to log into the host and not have it ask me to enter in my long / complex passphrase every time I ssh into another host. I've googled for some scripts that you can add to your bash configuration so that you won't have to do that. So I have to end up typing 'eval $(ssh-agent) && ssh-add' and enter in my passphrase every time. It's a little annoying. I've been dealing with this for a while and I could use some help. Here's my bashrc file with the lines on using ssh-agent and ssh-add in it: # .bashrc # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi # User specific aliases and functions SSH_ENV=$HOME/.ssh/env-$HOSTNAME function ssh_clean { d="$HOME/.ssh" f0=$d/known_hosts f1=$d/known_hosts_tmp cat /dev/null > $f1 while read host line; do if [ $host != "localhost" ]; then echo $host $line >> $f1 fi done < $f0 mv $f1 $f0 chmod 644 $f0 } # Initialize new agent and add authentication function start_agent { echo "Initialising new SSH agent on $HOSTNAME on $(date)" >> ~/agent # Start authenticating daemon # No authentications set up yet, just starting daemon! ssh-agent | head -2 > ${SSH_ENV} chmod 600 ${SSH_ENV} # Find SSH_AUTH_SOCK and SSH_AGENT_PID of the available daemon . ${SSH_ENV} > /dev/null # Add authentication to this and only this daemon ssh-add } if [ -f "$SSH_ENV" ]; then # Find SSH_AUTH_SOCK and SSH_AGENT_PID of the available daemon . ${SSH_ENV} > /dev/null # Check if the agent is still running ierr=0 ps ${SSH_AGENT_PID} > /dev/null || ierr=1 if [ $ierr == "0" ]; then echo > /dev/null else # If not initialize new agent and # add authentication start_agent; fi else start_agent; fi export PATH=$PATH:/home/iloshakov:/home/tdineen/eporter:/home/mrupapara:/home/tdunphy/bin:/home/ashoykhet:/home/tdineen/eporter export PUB='/homeuser/.ssh/id_rsa.pub' I'd appreciate any advice you may have!

VMware-tools has 4 options only for resolution!
by Yawei Guo 03 Mar '14

03 Mar '14

Hi Guys, It is surprised that VMware-tools gives 4 options only for resolutin after I install VMware-tools for CentOS release 5.10 (Final), a guest OS running with VMware player 6.0.1 build-1379776. The kernal is 2.6.18-371.4.1.el5 x86_64 x86_64. The host system is win7 64bit OS. The hardware is Thinkpad T440S with a FHD display, 1920 X 1080. The following is what I get when I run vmware-config-tools.pl. The VMware-tools is VMwareTools-9.6.1-1378637.tar.gz. I think that is the latest version. CODE: SELECT ALL <https://www.centos.org/forums/viewtopic.php?f=19&t=44910#>Please choose one of the following display sizes that X will start with: [1] 640x480 [2] 800x600 [3] 1024x768 [4]< 1280x800 Please enter a number between 1 and 4: [4] 4 Obviously it does not contain the resolution I need. The information I get with getinfo.sh has one line "VGA compatible controller [0300]: VMware SVGA II Adapter [15ad:0405]" VMware-tools worked well when I installed CentOS 5.5 for my virtual machine. What's wrong? Would you please help me? Thank you. Best Regards, Yawei

backing up pending at commands
by Frank Cox 02 Mar '14

02 Mar '14

I can easily get a copy of my pending cron jobs so I can keep a backup. "crontab -l > mycron.txt" is part of my backup script, and that does the job nicely. Is there a way that I can get a copy of pending at jobs for this purpose? I can get a list of pending jobs with atq, and I can show each job with at -c jobname, but I don't see a way to get something that is suitable for use as a file that I can keep as a backup of the pending jobs. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

Hey, http://zfsonlinux.org/epel.html If you have a little time and resource please install and report back any problems you see. A filesystem or Volume sits within a zpool a zpool is made up of vdevs vdevs are made up of block devices. zpool is similar to LVM volume vdev is similar to raid set devices can be files.

suggestions for large filesystem server setup (n * 100 TB)
by Götz Reinicke - IT Koordinator 02 Mar '14

02 Mar '14

Hi, over time the requirements and possibilities regarding filesystems changed for our users. currently I'm faced with the question: What might be a good way to provide one big filesystem for a few users which could also be enlarged; backuping the data is not the question. Big in that context is up to couple of 100 TB may be. O.K. I could install one hardware raid with e.g. N big drives format with xfs. And export one big share. Done. On the other hand, e.g. using 60 4 TB Disks in one storage would be a lot of space, but a nightmare in rebuilding on a disk crash. Now if the share fills up, my users "complain", that they usually get a new share (what is a new raidbox). From my POV I could e.g. use hardware raidboxes, and use LVM and filesystem growth options to extend the final share, but what if one of the boxes crash totally? The whole Filesystem would be gone. hm. So how do you handle big filesystems/storages/shares? Regards .
