When running OpenSolaris SX:CE >= snv_100 on different flavours of VMWare (Fusion, ESX, etc.) one needs to change edit the grub menu to include "disable-pcieb=true" at the end of the kernel line. To do this you will need to hit "e" to edit on the grub menu item, and then "e" on the line for the kernel. At the end of the line if there is no "-B" with options after that, add the "-B disable-pcieb=true". Once you have installed OpenSolaris, you can go ahead and edit your /boot/grub/menu.lst and add this there as well.

One gotcha when using exim to do authenticated SMTP one wonders why you keep seeing the following:

Return-path: <"email@add.re.ss"@server.host.name>
*snipped*
Sender: "email@add.re.ss"@server.host.name
*snipped*

One needs to modify your acl for acl_check_rcpt for authenticated SMTP connections to contain the sender_retain bit like below:

  accept  authenticated = *
          control       = submission/sender_retain

Restart your exim (in my case on FreeBSD I used /usr/local/etc/rc.d/exim restart) and send a email:

Return-path: <email@add.re.ss>
*snipped*
Sender: email@add.re.ss
*snipped*

One of my work colleagues, the ubergeek Ben Rockwood has started a podcast called SA Pro a podcast for Systems Administrators. In the first episode (episode zero) Ben chats together with with Joe Moore of Siemens and Mark Imbriaco of 37signals.

In the podcast we'll use one of two formats, classic 1-on-1 interview style and a round-table discussion format. This episode is the latter.

Together with Joe Moore of Siemens and Mark Imbriaco of 37signals we discuss the following questions:

1. What is the mark of a good SA?
2. What are the essential qualifications?
3. Does formal education and/or certs matter?

Whats really new and unique is that Joe, Mark, and I don't know each other. They both responded to a request for participants on the OpenSolaris SA's list and matched the qualifications I was aiming for, thats the extent of it. This is interesting because even though the three of us are in very different circumstances, have different histories, and are geographically separated, we're not very dissimilar. It amazes me how much unity there is among a group with so few governing institutions.

Busy catching up on the Release Engineering Schedule for FreeBSD version 4.10-RELEASE, and it seems slightly delayed.

None the less some pesky bugs have been fixed from what I've managed to establish, and it's going to be worth the upgrade.
