eeehm, it worked.
i think the output was incorrect bcs. i've scrolled up and down few times.
Code:
$ cat test.data | grep 100%
basesystem-8.0-5.noarch.rpm 100% of 2777 B 1665 kBps
bash-3.0-31.i386.rpm 100% of 1829 kB 63 kBps 00m00s
$
sorry guys
edit: but i'm still interested to know how to increase or decrease the transfer time out.
