RES: [FUGSPBR] [OFF] - Linux x Free

[Jorge Godoy]

Ainda nesta thread, não testei as maneiras de causar um crash no
FreeBSD descritas abaixo, mas ainda funcionam? Achei estranho nunca
ter pego isto em alguns anos de uso (2 de uso e uns 3 ou 4 de
"fuçação" no Free... ;o))


Sds,

the best sites I know about:

	1. http://sites.inka.de/mips/unix/bsdlinux.html 

	2. http://www.cons.org/cracauer/freebsd.html

both are from 2000 and compare FreeBSD with the old Linux 2.2 (running
the now outdated ext2 filesystem) - seems FreeBSD advocacy was easier
those days...

Even FreeBSD users recognize that the basic pkg tools are not very good
(and that's the reason why portupgrade exists).

Note that today, ports-like package management for third party software
is possible with a couple of Linux distributions. And there a plans to
enhance the Debian package management (http://telemetrybox.org/upm/).


Filesystems

	Linux supports different Journaling Filesystems (JFS)
	Easier with FreeBSD: only the UFS filesystem is available,
	and the FreeBSD Kernel stays slim!

	The ext3 filesystem for Linux is in productive state and
	already avoids annoying filesystem checks after crashes.
	Comparable functionality for FreeBSD is unstable but will be
	soon available with FreeBSD 5.0

	Perfomance und data security should be equal (at least from a
	home user's point of view). Linux with a JFS may offer better
	performance for some databases and mailservers.


Packet Filtering:

	FreeBSD users have the choice between ipfw, ipf and User PPP
	(or using them together) with readable filter rules. ipfw and
	ipf are both very powerful packet filters.
	
	Linux ships with iptables and some people claim that it has
	better performance and needs fewer rules. Maybe that's right for
	special purposes but convincing benchmarks are not available.
	True is that the iptables syntax is very sick



USB Support:

	FreeBSD supports only USB1 and there is not much documentation
	about USB configuration available. More decent for USB2 devices are
	Linux and NetBSD.



Ways to crash (aside from poor hardware):

	A FreeBSD is easy to crash: Writing to floppy with write
	protection, unloading Kernel modules while they are in use

	No problems with Linux crashes here ;-) 
	Serious: aside from booting a Knoppix on PC with only 128MB RAM
	or running the sucking Mandrake installer, I'm not experienced
	in crashing Linux anymore.



Other things I like about FreeBSD

	Configuring and installing a custom Kernel is easy: just editing a
	few lines in a config file and typing five commands - ready.

	The featureful and interactive user-ppp program for dialup.


Ciao, Mark
