Hi,

First I want to thank you for that great piece of software. I am using Udpcast in the opensource cloning solution OpenClone (http://openclone.nongnu.org/).

When testing the new Udpcast version 20090830, I discovered a bug. If I try to transmit gzip'ed data with this version, the receiver breaks the transfer after a very short period of time (usually less than a second).

For example:

$ udp-receiver -f /dev/null Udp-receiver 2009-08-30 UDP receiver for /dev/null at 10.10.10.254 on eth1:0 received message, cap=00000009 Connected as #0 to 10.10.10.194 Listening to multicast on 234.10.10.194 Press any key to start receiving data! bytes= 98 304 ( 6.17 Mbps) Bad base 98304, not multiple of block size 1456 Transfer complete.

$ gzip < /dev/urandom | udp-sender Udp-sender 2009-08-30 Using full duplex mode Using mcast address 234.10.10.194 UDP sender for (stdin) at 10.10.10.194 on eth0 Broadcasting control to 10.10.10.255 New connection from 10.10.10.254 (#0) 00000009 Ready. Press any key to start sending data. Starting transfer: 00000009 Disconnecting #0 (10.10.10.254) bytes= 98 304 re-xmits=0000000 ( 0.0%) slice=0112 - 0 Transfer complete.

Udpcast version 20081213 hadn't any problems with gzip'ed data.

Actually, the problem happened for all kind of data read from a pipe (not just compressed). This is now fixed in 20090912
