new wildebeest VMs
In an effort to improve performance, I've rolled out 4 additional wildebeest VMs:
- impala
- laddergoat
- saiga
- gazelle
Basically copies of antelope, they take up the 4 IPs preceding the existing wildebeest herd (so 2.26, 2.27, 2.28, and 2.29, respectively to the above given order).
The aim is to improve responsiveness under regular load, and possibly even explore running a playable minecraft instance (although memory requirements may be too much for such a thing).

updates
Applied available updates to lab46, www, and irc in preparation for the fall semester.
portfolios
The student pages now include portfolio links.
reboots
I restarted www in preparation of the fall semester.
opus processing
I've adapted several of my journal scripts to opus logic and launched the init script so students can initialize their opii. Hopefully I haven't overlooked any major bugs.

DSLAB DNS
It appears DNS in the DSLAB to the outside world was not entirely resolving… to BITS-related things it works fine, but to external sources like google, not so much.
I realized that the config was never set to let it reference outside DNS servers. This was fixed on juicebar by configuring forwarders in /var/named/etc/named.conf.options:
forwarders {
137.238.1.16;
137.238.1.15;
137.238.1.14;
137.238.1.12;
};
Restart named and bam! Problem solved.

GRUB via PXE
Spent some quality time in the DSLAB delving into figuring out how to get GRUB functional via PXE. The information available on the internet wasn't very good, and unclear to distinguish between what was valid for GRUB1 vs. GRUB2… so I put together a HOWTO for GRUB2 via PXE:

LAIR pod cleaning
We cleaned off the LAIR pod tables… so even if we don't do any additional cleaning, we're good for classes in the fall semester.
