Sorry, this got put on the back burner for a couple
of days. Things seem to have worked themselves out
on the server itself (lenny). I tried running curl
on the cl. That worked, so I tried aptitude update
with sources.list pointing to the localhost approx
proxy. Don't understand why, but it is working.
The problem persists from a remote client (a squeeze box),
though. Packages file downloads variously to between 4 &
6 per cent, then the download stalls for a minute or two.
The partially downloaded file then disappears and returns
as a zero length file which then downloads to between 4 & 6 per cent ...

And you were right:
approx: Nethttpd: Uncaught exception:
Nethttpd_types.Standard_response(-358247754, 0, 0)
appears over and over again in /var/log/syslog when the remote
clients chokes and starts the download over. Googling that only
turned up one bug report that seems to my naive eye to not
be a related problem, and anyway, was fixed in approx 3.3.0
which is what I am running.
Does the nethttpd error mean anything to anyone?
