Command
Introduction
Secure Shell Handler or SSH is a network protocol that allows data to be exchanged using a secure channel between two computers. LTSP uses it to enable secure communication between clients and the Server. SSH uses public-key cryptography to authenticate the client, this command rebuilds the keys.

All the following commands are entered on the server. Normally this would be having logged into your normal LTSP desktop and opened a terminal session, but it could equally be from an ssh session to the server. The key thing is that you do not run these commands from a client shell, as the client system is read-only.

I have run through these notes again and corrected the odd mistake and they do seem to work. At least until something changes!!
I have not yet got the init.d script working, but am able to successfully start adempiere and reach the login page.
I need to review the postgresql security settings as “trust” for all is probably unsafe.

RAM
LTSP website recommends 256mb for the core system plus 50mb per user:
Total RAM = 256mb + (25 users x 50mb)
= 1506mb
However Edubuntu recommends a different formula:
Total RAM = 150mb x 25 users
= 3750mb
We recommend you choose the greater of the two, and double-it if you can (see update below).

I have been told that installing package virtualbox-ose-dkms solves all these problems. I have installed and it reported that my modules were up-to-date, which is promising. I shall try and remember to update this page later, but I thought I’d write this now in case I forget!!

Yes once again I come to complete my tax return, last time it was a far from successful experience.
Given that that page is now a year old and my next year’s return is required, I thought it was an opportune time to update it. Unfortunately nothing much has changed, the list of personal tax applications has shrunk, as TaxCalc’s market domination continues. The only Linux-compatible competitor seems to still be ftax and it requires Acrobat Reader, which isn’t available for 64-bit Linux.

Scanning with LTSP 5 in Debian Etch or Lenny
At the time of writing these instructions worked for Etch, but have not been completed for Lenny.
Introduction
This is a description for a scanner physically connected to a terminal (not to the server).

Turns out this is as simple as:
$ sudo -i
# apt-get install nagios3
# cd /etc/nagios3
# htpasswd -c htpasswd.users nagiosadmin
Then point your browser at http://localhost/nagios3/.
