The primary disk is 150GB and the external usb disk is 20GB. As I check with the 'df -m' , with respect to the used space , the 20GB capacity seems to be sufficient. Can you please let me know how to modify my command to have the os installed on the primary disk to be cloned to the external usb disk ? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] KVM iptables rules
After I installed kvm I noticed that some rules are appended automatically by some tools that come with kvm packages(I installed all KVM group with yum) . The problem is that after I appended my rules I and used the /etc/init.d/iptables script to save changes in /etc/sysconfig/iptables I saw that after restarted the machine that tool appended the rules once again ... so now I have double entries for kvm rules. Does anyone know how can I block this mysterious tool to append rules in my tables ?

It's probably not well known, but Sherwin-Williams, a Fortune 100 company with two thousand shops across the country (and in some foreign countries), uses Linux in all their "shops"... all 2000 of them. Yep, walk into any Sherwin-Williams store and what you buy is run up on a Linux POS system. The manager who put his neck on the line by proposing and implementing this system (other (risk averse) managers in the company weren't supportive and didn't make it easy for him) ended up with a big bonus and a significant promotion. After all, he saved the company 2000 times what the Windows software would have cost... at least a million bucks, likely more. Of course at corporate headquarters they have about 250 UNIX servers to handle the back-end stuff, really not a lot of servers for a company its size. > The computer >> consultants we work with have suggested two options: >> >> - Moving to Windows Terminal server (cheaper) >> - Moving to Citrix with virtualized servers (more expensive but >> apparently much faster and more powerful). > > before picking an operating system for the central server, its a good > idea to pick the Point-of-sale system architecture. > > using terminal server/citrix/nx/etc type connectivity for POS from > remote locations means if the network is down, the cash registers are > down. thats not good. most POS systems have a local onsite store > server at each location, the registers are terminals to this server, but > usually run the cash register POS software directly, then the store > server communicates with the corporate mothership as needed, either live > or batching transaction logs as appropriate. > > different sorts of retail businesses have widely varying POS > requirements, for instance, the POS system for a restaurant chain is > very different than the one for a auto parts chain. > > All these questions should be sorted out long before getting into > implementation details like operating systems, hardware platforms. Wise words. Planning is always good. But Linux runs on anything, making it about as scalable as an OS can be. If your needs outgrow the hardware your data's on, you can move the whole system to bigger hardware, then re-purpose the old hardware for something else. The only reason for not having Linux on a box would be because the hardware support contract ran out. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
