Bruce, I didn't think to look for packet errors, last time there was a sizeable results upload.

But I looked at this package in Linux called trickle (that I've installed on my Debian system),
homepage of the pkg is http://monkey.org/~marius/pages/?page=trickle

If I use that as a wrapper (cmdline option "-u 12") around the exec of FAH504-Linux.exe, then it
ought to reduce the upload bandwidth in my setup, so that I have a bit of unused in the up direction.
The utility also has available cmdline options for peak detection window size, smoothing time, and
smoothing length. I think this is a promising possibility. The main FAH executable is dynamically linked,
so I think this will work.

Perhaps I'll find a time when my f@h job in progress is almost ready to finish, then interrupt it and insert
the trickle command on my next f@h startup, and manually test my ssh/inet access to the system then. Larry

Just running an experiment (to see whether I can forcibly limit the upstream bandwidth).
The current WU I have is ...
Project: 2453 (Run 75, Clone 31, Gen 2)
Protein: p2453_Fragment-Receptor HDU
The logfiles and the pstree output look fine. What I did is to replace my FAH504-Linux.exe
executable file by the following wrapper script —
Code: Select all
#!/bin/sh
exe="${0}"
exe="${exe%%exe}bin"
[[ -x "${exe}" ]] || exit 2
[[ -x "/usr/bin/trickle" ]] || exit 3
exec /usr/bin/trickle -u 12 "${exe}" "${@}" || exit 1
and I renamed the original executable to be called FAH504-Linux.bin
This is a hack, a kludge, but I want to see whether it works. Will look at it when it uploads (I might
miss it a few times), will post back here if anything good happens. :ewink: Larry
