Hello,

It seems that I can transfer (iso) files without problem, but I am unable to transfer directory trees through a pipe.

commands

# udp-sender --log log.txt --pipe "tar -cvzf - dir/" # udp-receiver --log log.txt --pipe "tar -xvzf - "

I keep getting the following error in the receivers [...] dup2 -1->1: Bad file descriptor [...] Any idea out there? :-)

I found the error (is it one?): The pipe command receives the udpcast output file as its output (while updcast then writes to a pipe leading to the pipe command). If you don't use the "--file" option the resp. file descriptor is -1. Solution is simple: specify both, --file and --pipe. Have fun! Björn
