How about the following test:

(network broken with iptables rule that blocks all packets)

debian-gta02:~# time wget -O /dev/null --timeout=10 http://www.debian.org/; echo "ret = $?"
--2008-08-20 14:07:10--  http://www.debian.org/404
Resolving www.debian.org... failed: Connection timed out.
wget: unable to resolve host address `www.debian.org'

real    0m10.066s
user    0m0.015s
sys     0m0.050s
ret = 1

(working network)

is my first guess. I verified that sed of busybox supports -i but I
did not test this on non-debian systems yet.

Very unfortunate. Do I read the manual page correctly in that it
doesn't support remote command execution at all so that I can't do

ssh foo 'cat > bar' < bar

either? Also, openssh-client support compression which is very nice
with GPRS (ppp compression obviously does not help with encrypted
traffic).

Thanks.

Added to wiki.

Ah yes, when we have non-root users this of course becomes useful.

Yes I'm subscribed. Too late to remove the CC though :-)
