Building a KVM Proxy

Traditionally we seldomly connect our KVM from the port directly to the server that consists of usb for keyboard and mouse, vga cable for display purposes. More advanced you may have an experience using the iKVM which connect all you kvm port from the internet where you can have a remote location as long as you have the internet connection. When technology evolve, physical server are becoming obsolete since we have the virtualization technology. Since that to access your virtual machine (vm) are more easier. Instead of using SSH, like a Xen hypervisor, the Xen itself can host as a KVM server and map to the vm on different port as configured from the config file.

Exim force remove frozen queue

One of our client got a spam message in queue and almost 14mil of message in queue has been generated by the culprit. The exim itself generated a log file message which do a lot of write process to the log file. Because of that, the server inodes also got exhausted. Really need some cleanup for them :) I've tried to remove the frozen mail queue using several method, and the best command is : exim -bp|grep frozen|awk '{print $3}' |xargs exim -Mrm Other command that you can try : xiqgrep -zi|xargs exim -Mrm exim -bp | awk '/^ *[0-9]+[mhd]/{print "exim -Mrm " $3}' | bash exim -bp | exiqgrep -i | xargs exim -Mrm good luck!
