I believe you can buy support for the product for them, if you need it. Qemu might be a truely OSS solution. I personally have not used it in quite a long time, though, but I've heard it can be reasonable when used with the accelerator module. robert

Upgraded BackupPC (3.0.0) in the Testing Repository
by Johnny Hughes 01 Mar '07

01 Mar '07

There is an upgraded BackupPC in the testing repository. It is version 3.0.0, which was released in January. The setup differences between version 2.1.2 and this version is that some file directories have shifted locations: 1. /var/lib/backuppc/conf is now instead /etc/BackupPC/ 2. /var/lib/backuppc/log is now /var/log/BackupPC =============================== If you are upgrading ... you _CAN_NOT_ just copy your old config.pl config file into /etc/BackupPC can continue on ... you need to migrate in any changes that you made to original file to this config.pl file as there are updated options in the new file. How is the best way to do that ... you did save a copy of the original file prior to changing it ... right :P If not ... here is what I did: ----commands---- cd /tmp mkdir backuppc cd backuppc wget http://dev.centos.org/centos/4/testing/i386/RPMS/backuppc-2.1.2-3.c4.centos… rpm2cpio backuppc-2.1.2-3.c4.centos4.i386.rpm | cpio -idv ----end commands----- You should be in /tmp/backuppc and you should see all the files (extracted) from the original RPM in there ... inside the /tmp/backuppc/var/lib/backuppc/conf/ should be an original config.pl file. You can use that file to create a diff file that you can read to make changes to the new config.pl file. here is what I did prior to upgrade: ----commands---- cd /var/lib/backkuppc/ cp -a conf conf.bak cp -a logs logs.bak cd conf.bak cp /tmp/backuppc/var/lib/backuppc/conf/config.pl config.pl.orig diff config.pl.orig config.pl > config.pl.diff ----end commands---- Now you are ready to upgrade ... you will need to enable the testing repo to do the upgrade (or download the files manually and install manually via RPM). How to do the upgrade via yum: Put the testing repo file into /etc/yum.repos.d/ : http://dev.centos.org/centos/4/CentOS-Testing.repo (the file is disabled by default) Once you have the file in place, use this command: ----commands---- yum --enablerepo=c4-testing upgrade backuppc perl-Compress-Zlib perl-File-RsyncP perl-Time-modules perl-XML-RSS ----end commands---- (that command in all on one line if it wraps in your mail client) You can use that diff file from above to manually add new changes to the /etc/BackupPC/config.pl file after upgrade. Also after upgrade, you can move all the files in /var/lib/backuppc/log/ to /var/log/BackupPC/ Once everything is configured ... restart backuppc and httpd Once everything is working, you can get rid of the following directories in "/var/lib/backuppc/" ... conf, conf.bak, log, log.bak If you are installing new, replace "upgrade" with "install" in the above yum command ... and see the README.centos file in /usr/share/doc/backuppc-3.0.0/ after install Here is the original announcement, which also has good info: http://lists.centos.org/pipermail/centos-devel/2006-April/002216.html Thanks, Johnny Hughes

DVD rom questions
by Steve Campbell 01 Mar '07

01 Mar '07

I'm running CentOS 3 and have just installed a Liteon lightscribe DVD/CD unit. I firstly realized I didn't know exactly how to mount it, as /dev/dvd didn't exist, I didn't want to generate anything if it already existed, and I didn't want to mess up my cdrom unit that works just fine. I mounted the device though the X window just to see how it might mount, and find that it mounts /dev/cdrom1 on /mnt/cdrom1, regardless of what type media is in the drive. Does this sound proper? Should I mknod(?) something for the /dev/dvd device and if so, what should be the parms? I then tried to find a movie viewer on the machine, and only found mplayer. I couldn't get it to work properly due to the configuration options (not a very powerful machine). What does anyone use for a DVD viewer? And lastly, what are recommendations for implementing the lightscribe functions that exist on the drive? Any help is very graciously appreciated.

It is worth looking at. I Yup, I mentioned that as an option on my initial list. I've got a test box running CentOS 4.4 and VMware. It's a heavy weight solution, but has advantages (I could potentially run Solaris 86 in a session, Windows in a session etc). > used to run a bunch of vserver instances, and while those did have some > interesting advantages, I ended up rebuilding everything using VMware Server as > I retired hardware.

This was my preferred approach (mostly for the reasons you suggested) but the overkill of a whole VM for just an sshd process is what lead me to asking the question here in the first place. Thanks for your input! -- rgds Stephen

Add RAID after install in one disk
by Mário Gamito 01 Mar '07

01 Mar '07

Hi, I had this hard time installing a server with RAID 1 by software. I always got an error from GRUB and no booting. So, i've installed CentOS 4.4 normally in only one disk. Question is: is it possible now to make a RAID 1 by software with the other disk ? If so, how ? I'm completely lost here. Any help would be appreciated. Warm Regards, Mário Gamito

Well after your advice I thought I better had take a look at FreeNX. 10 minutes later, all up and running and I agree, it is a lot nicer solution. In case anyone else is considering FreeNX, check out http://wiki.centos.org/FreeNX follow the write up and you will be up and running in 10 mins. Thanks Les and the author of the wiki page. Dean.

I was hoping to use the software we already have installed (Putty&Cygwin) but if this fails I will look into your suggestion. Dean

ptyxx ports
by Ted Gervais 01 Mar '07

01 Mar '07

With the 2.6 kernels we have lost the ability to use ptyxx and ttyxx for the installation of various ports. I am thinking of attaching a modem etc to an axip or other similar port and for that I always used ptyxx/ttyxx to do this. How is this done with the 2.6 kernels? -- Ted Gervais 2381 Loretta Ave., Coldbrook Nova Scotia Canada b4r 1a7
