I am not looking for some general information but some thing concrete from an authentic source. Where does one read about cyber laws concerning this? Is there any particular mailinglist that discusses cyber lawsin India? Any instance of any body convicted in India for just port scanning? Is it categorized under cracking? Thanks --Siju </pre> Siju George 2011-07-24T15:02:54 http://comments.gmane.org/gmane.os.bsd.india/731 <pre>http://www.atmnis.com/~proger/openkyiv/openkyiv2009_proger_sys.pdf --Siju </pre> Siju George 2011-07-19T16:46:59 http://comments.gmane.org/gmane.os.bsd.india/730 <pre>Hi, One of the DragonFlyBSD Backup Server has around 10 years of Company  Archives. This is the result of de-dup feature Short Sumary before dedup of firtst Hard Disk Filesystem                Size   Used  Avail Capacity  Mounted on Backup1                   454G   451G   2.8G    99%    /Backup1 Short Sumary after dedup of firtst Hard Disk Filesystem                Size   Used  Avail Capacity  Mounted on Backup1                   454G   313G   141G    69%    /Backup1 Reclaimed 138 GB i.e 30% of Disk space without deleting anything or considerably affecting the perfomance of the Server. Full Story: The first backups server was Debian Sarge, then Debian Etch and then OpenBSD with RAIDFRAME mirrors because it was the only Unix/Linux that would even detect the 120 GB hard disks we had back then. Later I turned to DragonFlyBSD due to HAMMER ( No fsck, No RAID Parity chceks and Easy FS Snapshots ) So this Dragonfly backup server has around 10 years old backups of 1) Web files of Projects ( html, php, images etc ) 2) SQL dumps both zipped and unzipped .Hammer snapshots gave me the luxury to do http://www.dragonflybsd.org/docs/real_time_backup_server_for_microsoft_windows__44___linux__44___bsd_and_mac_os_x_clients/ But now we have SQL dumps of induvidual databses taken every hour and made available to the developers using snapshots in the same manner :-) 3) MS Word, Excell Doc files - Company documents and User backups 4) PSD files and such from Designers which takes a larg space. 5) Git, SVN repositories backup 6) Virtual Machine images ( mostly qcow2 ) 7) Configuration files of several servers and other details backuped daily/hourly os some times every 15 minutes and maintained with coarse grained snapshots without pruning. 8) Several Softwares and CD ISO images 9) Video/Audio files such as mp3,avi.flv,mpg and so on. The OS version currently is DragonFly v2.11.0.247.gda17d9-DEVELOPMENT  Processor is AMD Athlon(tm) 64 Processor 3400+ (2193.63-MHz 686-class CPU) Memory is real memory  = 2113336320 (2015 MB) avail memory = 2029342720 (1935 MB) with four 500GB SATA Disks mirroring PFS from each other and also from another Dragonfly Backup Server on a differrent floor using 'mirror-stream' started at boot using cron with an entry similar to &lt; at &gt;reboot /sbin/hammer mirror-stream /Backup1/Data /Backup2/Data &amp; I have never reinstalled the OS but kept following the development version from July 2009 so that is two years of rolling release which is a great advantage in itself :-) The first Disk is mounted as /Backup1 and seems to be a good Candidate for dedup because it is almost full.

I have 3 primary partitions on my WinXP laptop; I installed DragonFlyBSD on the third partition that is beyond 60G. I skipped the step to install the boot blocks, since I want to use NTloader to boot DragonFly. Later, I copied /boot/boot1 to c:\bootsect.dfly and added the following entry to c:\boot.ini. C:\bootsect.dfly="DragonFly" FWIW, this method worked fine with FreeBSD-current. However, upon trying to boot DragonFly from NT loader, the screen goes blank for a few seconds, and then, the system reboots. Upon googling, I found the following mail in the dragonflybsd-user archive: http://kerneltrap.org/mailarchive/dragonflybsd-user/2004/12/31/135686 I haven't come across mail/FAQ/webpage which confirms that the method described above works for DragonFlyBSD.

I am an alumnus of IIT Roorkee and currently I am HOD-IT at MIT Meerut. I am also the coordinator of GLUG Meerut ('www.glug-meerut.org' and 'groups.google.com/group/glug-meerut') and we have realized that GNU/Linux will always be a clone of BSD/BSD based Systems. We have embraced PC-BSD 8.0 on virtual box for a full migration of Engineering college btech labs on BSD UNIX. Personally, I have tried to contribute to the community by making UP state technical university final year CS and IT labs FULLY on UNIX in the course curricula itself. I was in IIT Kanpur for a curricula revision and I tried to make the most for open source community. Kindly consider this as a formal HELLO broadcast to all of you. Looking forward to see more UNIXers attaching to this list.
