Whats the differnce between the BSD and the HP-UX ?

[Sree Harsha V]

Could any body let me know what are the main diff between the BSD unix and the HP-UX and also please let me know how good is HP-UX is best in networking??

BSD (stands for Berkeley Software Distribution)
is the ancestor of all Unices (and thus also HP-UX derived from it).
If you query any search engine you will find plenty of references.
There was also a chart available on some website (whose URL I've forgotten) that showed in a horizontal tree all the ramifications of all Unix derivatives from its root (very stunning and bewildering).
The original Unix code was held by AT&T and disclosed to the Berkely Uni for "educational purposes" temporarily, whose students therefore further developed great parts of what today is common Unix fare, and who offered their works for only a nominal tapes charge.
Especially the networking parts of the code to a high degree are based on the Berkeley works, and the BSD Socket API nowadays seems common in most Unices.
As the industry discovered a real market for this OS money and license quarrels came into play and the great version forking began.
When later the rights were bought by SCO, who since then are the only ones eligable to name their product Unix, and currently trying to allege and sue almost everyone to have "stolen" parts of their code, some free BSDs forked off and completely rewrote any left AT&T code from scratch.
They now offer their BSDs for free.
So it should be very easy to you to find out the differences between say HP-UX and FreeBSD.
FreeBSD is mostly popular for server and desktop usage on the x86 platform,
while NetBSD is claimed to be the OS to support the widest array of different hardware.
If you are into strong security features the OpenBSD should best suit you, who are also the developers of OpenSSH.

Shalom,

Other obvious differences:
1) HP-UX is not open source and few people even at HP see the source code.
2) HP-UX costs money.
3) HP-UX is a very reliable, industrial strength OS that only runs on HP certified hardware.

>SEP: 3) HP-UX is a very reliable, industrial strength OS that only runs on HP certified hardware.

And these are PA-RISC and Integrity Servers.

Thanks a lot . I appreciate that. People like you are very good help for the guys who are in learning stage like me.

For reference, the AT&T branch was "System V". Nearly all current commercial UNIX platforms are SysV-based, though they frequently implement some BSD features or interfaces.

Hi Sree:

This article and its accompanying image of the evolution of Unix should prove enlightening:

Hi Sree:

sure, HPUX is BSD based, but it differs enough. for me i believe *BSD is better then HPUX. but then again i am a strong believer in open source development models.
HPUX is by far not the best in networking, compared over the whole range of unix versions. compared to BSD, it loses to NetBSD.
HPUX is also not the most secure, OpenBSD does far better in this.
You buy HPUX and the HW it runs on, because you want and need the best support for your system possible and are willing to pay a lot of money for it (it is important to pick the highest possible support option you can afford because the lowest options are not really worth it).

Many thanks JRF,
that was the pedigree/genealogy tree of Unix that I was referring to.
Bookmarked it again :-)
