> Did truss only show the waiting for input /sleeping or was more happening?
About once every few minutes is would spit out some output, but most of the
time it would just sit there poling.
For instance, from my current test, here's some output from truss. Each
I let each output go for a few minutes. I waited to see if I could capture
output from one of the processes, but I got too impatient.

> What is logged in your syslog ?
Nothing, amanda doesn't normally send anything to syslog on my system.
Here's my setup on the server:
---[ /etc/services ]----------------------------------------------------------
amanda 10080/udp # Amanda backup client
amandaidx 10082/tcp # Amanda index server
amidxtape 10083/tcp # Amanda tape server
------------------------------------------------------------------------------
---[ /etc/inetd.conf ]--------------------------------------------------------
amanda dgram udp wait root /usr/libexec/amandad amandad
amandaidx stream tcp nowait root /usr/libexec/amindexd amindexd
amidxtape stream tcp nowait root /usr/libexec/amidxtaped amidxtaped
------------------------------------------------------------------------------
The clients each have the same /etc/services entries, but only the "amanda"
entry in inetd.conf.
