My application is only the server, the receiver is smbget from Samba, so
I don't feel responsible for it :-)
Still, when run over Ethernet, it works fine without waiting for
timeouts to expire.
To reproduce this:
- smbget is from samba, you probably already have this
- gatling (my server) can be gotten from
cvs -d :pserver:cvs@xxxxxxxxxxx:/cvs -z9 co dietlibc libowfat gatling
dietlibc is not strictly needed, but it's my environment.
First built dietlibc, then libowfat, then gatling.
