low level format hdd using dd

Posted by MaEl in: Bits-and-Bytes Comments (0)


Need to securely wipe HDD data?? Got 2nd-hand HDD?? Got bad sector?? Yes, It’s time to do a low level format(Zero-fill). In Linux, we can use dd. The command is as simple as
dd if=/dev/zero of=/dev/hda &
[1] 5645

Set it as background process and it will print out the PID. This process takes a while depending on the HDD size.WARNING! This will destroy ALL data on the HDD, all boot sector info and all data on all partitions. To watch the status, just enter
kill -SIGUSR1 5645
62796+0 records in
62796+0 records out
65846378496 bytes (66 GB) copied, 1748.1 s, 37.7 MB/s
replace 5645 with the PID

Clarkconnect DynDNS,EveryDNS updater

Posted by MaEl in: Bits-and-Bytes Comments (2)


Clarkconnect has its own dynamic IP service and automatically map system name.pointclark.net for you. It has its own daemon to update the IP address automatically. But for me, I don’t think the *.pointclark.net domain is useful for me. I’ve used the DynDNS dynamic IP services for several years and I don’t like to have to inform others about my new domain. Plus, I used EveryDNS dynamic dns nameserver for pixca.net and I need to update it if my ip change.

Server Moved: From Ubuntu to Clarkconnect

Posted by MaEl in: Bits-and-Bytes Comments (0)


At last.. I got timed to update my webserver.. It have been running Ubuntu Server 7.10 since January 2008. The best thing about Ubuntu is its community support and software support. Software and library are ready to used.. no need to compile. Inheriting debian apt-get make software installation a breeze. Great to linux-noob like me :)
