Le dimanche, c'est le Sun-day

Nous, chez Ornix, on n'est pas des guignols.^[1]

Pour vous le prouver, nous avons essayé d'installer ce dimanche 23 octobre, une distribution Debian GNU/Linux 3.1 (Sarge) sur une Sun Enterprise 3500 reluisante, donnée à l'association. Pas de chance pour nous, le contrôlleur SCSI Fiber Channel (module socal) est loin d'être facile à installer et n'est pas supporté par l'installateur Debian. Après plusieurs heures de tentative de dumping de firmware depuis un pilote Solaris 9 à coup d'objdump et de dd, nous avons dû nous résoudre à abandonner.

La suite bientôt, on l'espére... En attendant elle sert de chauffage à notre président préféré.

Tune your OpenBSD/sparc

# sysctl hw.model
hw.model=SUNW,SPARCstation-5, MB86907 @ 170 MHz, on-chip FPU   
# export CFLAGS="-mcpu=supersparc"
# cd /usr/src && make build

This reduced my ssh connection establishement delay from 4~5 sec to 2~3 sec.

Wanted: Sun sbus NIC

I am looking for an Sun SBUS Ethernet or FastEthernet network controller.

If you live in EU and have one you do not need anymore...

NetBSD definitively rocks !

On the other side (read my last entry), I have a SparcStation on which I can only run Solaris (no !), NetBSD or OpenBSD.

Since OpenBSD definitively sucks, I tried to install a NetBSD 2.0_BETA. After one hour I successfully made an ISO with a daily build.

NetBSD is cool. It's small, it works, it's a LOT faster than OpenBSD and the installation process of version 2.0 is a little more friendly than 1.6.

Sure I would have prefered running Debian on this box, but Linux kernel does not support this Sparc processor MMU (Fujitsu).

OpenBSD definitively sucks !

Today I worked on my new network installation: I decided to build a router connected to 3 networks (ext, adm and dmz).

Since I "only" have a 512/128 Kb DSL connection, I like to do some QoS (prio on upload). The best way I found to do this was to use altq under OpenBSD. I used it for a while.

So, I re-installed OpenBSD 3.5 on a another machine (small Pentium 120) and put my old pf.conf from the old machine. Then I did a ssh another-server-far-on-the-net and... the connection got stuck at SSH2_MSG_KEX_DH_GEX_INIT sent... And you know what ? One of my friend had the same problem since two days with his gateway running OpenBSD 3.5...

Finally, I discovered that using pass out all keep state instead of pass out all in packet filter now blocks some SSH connections. It worked under OpenBSD 3.4, 3.3, for me and surely before.

Altq and pf definitively rock, but I will be HAPPY when NetBSD or FreeBSD people will have fully pf/altq integrated in their stable branches.

OpenBSD is definitively a f****ed buggy OS.
