Ibland sitter man där och får inte ihop syntaxen på ett kommando. Ett av mina favorithatobjekt på området är find.
OpenSSH 5.3 annonserades för några dagar sedan och markerade också tioårsdagen för projektet. Idag skeppas ju allting med OpenSSH så att kalla det framgångsrikt känns att ta i i underkant. Det är alltid bra att ha lite OpenSSH-kunskap i bakfickan...
Jag har testat att boota OpenSolaris 2008.05 och OpenBSD 4.4 på min eee PC 900 men de hänger sig efter ett tag båda två. Just nu håller jag på att installera FreeBSD 7.1beta2, vi får se hur det går...
Jag beställde ett CD-set med OpenBSD 4.4 och idag dök den upp, snyggt förpackad i ett dvd-keepcase som det heter.

- OpenBSD 4.4 RELEASED -------------------------------------------------
Nov 1, 2008.
We are pleased to announce the official release of OpenBSD 4.4.
This is our 24th release on CD-ROM (and 25th via FTP). We remain
proud of OpenBSD's record of more than ten years with only two remote
holes in the default install.
As in our previous releases, 4.4 provides significant improvements,
including new features, in nearly all areas of the system:
- New/extended platforms:
o OpenBSD/sparc64.
Fujitsu's SPARC64-V, SPARC64-VI and SPARC64-VII processors are supported
now, which means that many of the PRIMEPOWER machines and the SPARC
Enterprise M4000/M5000/M8000/M9000 work now.
Sun's UltraSPARC VI processors are supported now. Many of Sun's
mid-range and high-end servers with these processors or UltraSPARC III
and UltraSPARC III+ processors work now.
Sun's UltraSPARC T1 and UltraSPARC T2 processors are supported now,
which means the sun4v architecture is now supported and machines like
the SPARC Enterprise T1000 and SPARC Enterprise T5220 work now.

and 4.4, look at

Even though the list is a summary of the most important changes
made to OpenBSD, it still is a very very long list.
Om man inte har något emot att lägga på en resurskrävande skrivbordsmiljö kan man installera GNOME enkelt på OpenBSD - för mig som kör OpenBSD på lite äldre hårdvara just för att det är resurssnålt är det ingen vidare bra idé men kör man det på en hyfsat modern maskin kan det väl vara all idé att få en skrivbordsmiljö man känner igen?
OpenBSD är en bitch att installera, det både känns och är en riktig text-installation ala mitten av 90-talet. Den kanske knepigaste biten är partitioneringen av disken.
användare under installationen) har du ingen grafik och möts av en enkel prompt i textläge.
Så har man gått igenom den:
Min kollega Mike ska flytta till Zurich (han har fått jobb på IBMs labb där) så han frågade om jag ville adoptera hans Power Mac G3 - och det ville jag naturligtvis. Igår var jag och hämtade den och nu undrar jag naturligtvis vad jag ska installera på den. Klart är att den får bli server, processorn ger knappast den oomph man vill ha i en interaktiv arbetsstation - även om jag inte riktigt har klart för mig vilken klockhastighet den har (kring 400MHz iaf) så är den ju trots allt från början av 2000-talet och det har ju hänt en del sedan dess...
Det finns ett community med Mac-användare på IBM och det körs pilottester internt för att använda Mac OS X som en plattform.
Mac OS X 10.5.5 är släppt och rekommenderas för alla användare av Leopard.
Så du har kört Linux ett bra tag och vill testa något nytt men har ingen egentlig lust att radera och installera om? Varför inte prova Depenguinator och få din Linux utbytt mot FreeBSD?
Innan Unix fanns Multics. Unix gjordes med designideerna från Multics och vi har fortfarande mycket i dagens Unix/Linux/BSD-operativsystem att tacka för mycket av designvalen i det.
