[CentOS] Power Cut
Dear All I am using a centos server for cdr billing and mediation device on a remote network. I am experiencing problem that I am suspicious it comes from main supply power cut at the remote site. The power supply to the remote site comes from battery charger that will be automatically switched in circuit under main supply power cut but cannot provide adequate power for more than 2 hours . I am suspicious that the remote system is suffering from many frequent main supply power cut . Can you please do me favor and let me know if there is any log on my centos server that I can check to see if there would be many frequent power cut there ?

Hi, You don't have to install it. Clonezilla it's a Live CD: you boot from it, do your thing and you're done. It's way better than using dd because it's filesystem-aware and will only copy the used bits. I have never used clonezilla's GUI. Hmmm, maybe I had but never noticed. To the OP, clonezilla is in a different level than dd. Yes, it can copy a local drive partition to another local drive partition, but it can also copy, say, and entire drive -- logical volumes included -- into images in another machine using ssh while keeping the different partitions separated. And, as Jorge said, only copying what was changed.

Re: [CentOS] disk cloning ?
gparted and if it is the system-partition a Live-CD with gparted Excuse me, the source hard disk is a second hard disk connected to usb drive . The actual scenario is the main hard disk is my centos machine and the second source hard disk connected to usb port and the target is the third hard disk connected to usb port. Is it still necessary to use gparted with live cd or there is another simple procedure for this scenario? In the meantime, If I want to format the target hard disk with the same geometry as the source hard disk what can I do to accomplish that ?

To get you started, this looks like an interesting overview: http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-fw.html Also, if you get daring and want to try writing rules for yourself, Mike Harris has a nice template configuration for iptables: http://mharris.ca/iptables/mharris-iptables-example-config-1.2.txt Read up on iptables, understand the concepts behind it.

With respect to the above configuration, can you please let me know how can I just forward Internet traffic right from my centos connected to the net toward the windows node machine and thus enabling the windows machine to have Internet service (without any iptables rules set at the moment)?

[CentOS] make install?
Dear All I downloaded the octave-3.4.2 and tried to install it on my centos 5.6 as the following: #./configure But it prompted for lack of a c compiler, so I tried to install gcc first and then re-executed it and it was successful. #make But it prompts as No targets specified and no makefile found. #make install But it prompts as No rule to make target 'install'. I had the same steps for installing applications when I was on my centos 5.0 machine. Can you please let me know what is wrong my case?
