Here are the packages required to use hpasm on a Debian distribution.
This has been tested on Debian 3.0r1 with an "Debian unstable" kernel 2.4.22
on a DL 380 G2 and may not work for you.

Procedure to use it is the following:

As root, download 
debian-hpasm.tgz
hpasm_6.40.0-17_i386.deb
ucd-snmp_4.2.5-8_i386.deb
ucd-snmp-devel_4.2.5-8_i386.deb
ucd-snmp-utils_4.2.5-8_i386.deb

and place them under the /root subdirectory.
Then do 
cd /root
(cd / ; tar xvfz debian-hpasm.tgz)
/usr/local/bin/install-hpasm


Ignore the warning given uring installation due to directory
differences between RedHat and Debian (The LSB should help 
but clearly here doesn't :-)

Add the launch of ucd-snmp and hpasm to your startup/runlevel.
