Hardware

Mara is a Sun Netra T1 AC200 donated by Charles Leahy (charles). It's a 1U UltraSparc IIe box with 1GB of RAM and two 10K Seagate 73GB Cheetahs. It is also one of the few machines in our rack which is installed with the correct rackmounting kit.

OS

It runs Debian GNU/Linux 4.0 (etch) and not much else right now.

Storage

It has a 3GB RAID 1 root and a 65GB RAID 1 data partition mounted on /tardis/www/



The following information should be for historical interest only.


Details on lifetime as router:

Other Information:
IPv6 Tunnel

Ace has been commissioned (as of 30/09/10) as Tardis' router. At some point it may be put in a HA setup with King. RIP sungem.

Hardware

Ace (formerly mara) is a Sun Netra T1 AC200 donated by Charles Leahy (charles). It's a 1U UltraSparc IIe box with 1GB of RAM and two 10K Seagate 73GB Cheetahs. It is also one of the few machines in our rack which is installed with the correct rackmounting kit.

OS & Storage

It is running Debian Lenny 2.6.26-2-sparc64 and is set up with two RAID1 partitions: one 3GB root and another ~70GB partition for /usr.

Routing

Still todo :)

Things that are broken

There have been occasions where ace's networking has died completely, and it had to be rebooted. On closer inspection, this message was seen in syslog:

12:47:21 ace kernel: [955103.491804] eth0: RX MAC fifo overflow smac[02010400].

It's likely that large amounts of data or connections (such as when a system decides to do a full apt-get update/upgrade) are causing this to occur. Hopefully someone can get a kernel memory dump the next time this happens, so we have some more detail for a bug report.


The following information should be for historical interest only.

Services

Mara currently runs some of the most recently set up vhosts but has not yet taken over the bulk of the web hosting. This is mostly waiting on someone playing with the apache configs and suexec settings. It has rails installed. I vote we make 2.0.tardis point to mara :)

Apache Installation Issues

While attempting to get apache up and running as per the instructions here, I caught a snag as mara doesn't have tardis-packagetools installed from the tardis repository. However, after adding the tardis repository to /etc/apt/sources.list, the following appears:

Failed to fetch http://packages.tardis.ed.ac.uk/debian/dists/sarge/main/binary-sparc/Packages.gz  403 Forbidden [IP: 129.215.149.99 3128]

I'm guessing this means somebody needs to play with the firewall or the routing or something. It would be nice if somebody who knows what they're doing could handle this.
