If you repeat the ls command, you then get *these* messages:
shell-init: could not get current directory: getwd: cannot access parent directories
job-working-directory: could not get current directory: getwd: cannot access parent directories
but you get access to the files. Could this be related to the fact
that I compiled PLIP support for the first time? I cannot see any plip
in /proc/net/dev!! Is PLIP up-to-date?
Anyway, here are the benchmark comparisons. You can make your own
benchmark comparisons via WWW, from:
http://neon.ingenia.com/cgi-bin/bm-request
During the weekend, I will probably finish work on a new version that
will allow the presence of more than one benchmark log file
collection.
