Seems like a bunch of extra stuff… update-motd?

Installing NFS to hack around. Eventually storage on lordshiva will be via usb disks.

I made sure the nfs-kernel-server was also installed on where the disks were and added to /etc/exports something like:

/home/Music lordshiva(ro,sync,no_subtree_check)

and ran sudo exportfs -av

The on the SheevaPlug:

sudo mkdir -p /nfs/Music
sudo mount homeserver:/home/Music /nfs/Music

And updated /etc/gnump3/gnump3.conf to point to /nfs/Music

updating what munin monitors

Running the following commands will make some recommendations on additional things munin can monitor.

# munin-node-configure --shell --families auto
# munin-node-configure --shell --families contrib
# munin-node-configure --shell --families manual

Just cut-n-paste the ones you want to enable into a root shell. Remember to restart the daemon too.

root@LordShiva:~# ln -s /usr/share/munin/plugins/ntp_offset /etc/munin/plugins/ntp_offset
root@LordShiva:~# ln -s /usr/share/munin/plugins/ntp_ /etc/munin/plugins/ntp_europium_canonical_com

SheevaPlug as a mini-printserver

The pre-installed Ubuntu doesn’t include any kernel modules, but thought I’d try using the SheevaPlug as a mini-print/scan server for my hp PSC 1510 All-in-One printer/scanner.

Install cups which pulls in a ton of other packages as well as the open source print management tools from Hewlett-Packard, hplip

Hmm, during the install I plugged in the printer and checked dmesg to see if it was recognized. The lanmap process appears to have had a problem allocating memory:

When I tried to killall lanmap, ssh sessions hung. I could get in via console still. The network seemed to be a bit wonky, so rebooted.

Hmm, scary kernel messsages

This is after the reboot and seems to be when hal is starting up on install. Install is slowing continuing.

I’ve removed just hal, apt-get --purge remove hal

Hmm, now it appears that the pre-install Ubuntu/Jaunty doesn’t include any kernel loadablel modules for things like USB printers. Time to install stock Debian on this beastie.
