Hello listamtes,
Here's is a curious issue: netcat (nc) seems to not do UDP for me, even
though TCP works flawlessly. Not even on the local host.
Here's the "server session" I am running:
cat test.dd | nc -l -u -n -k -v 2456
(test.dd is just a large file with random data)
Here's the client:
nc -v -u 127.0.0.1 2456 | dd of=/dev/null
^C0+0 records in
0+0 records out
0 bytes (0 B) copied, 219.944 s, 0.0 kB/s
Here's what netstat reports:
netstat -a -n | grep 2456
udp 0 0 0.0.0.0:2456 0.0.0.0:*
udp 0 0 127.0.0.1:52394 127.0.0.1:2456
ESTABLISHED
unix 3 [ ] STREAM CONNECTED 12456
So the connection is established - but no data appears to be getting
transferred.
This behaviour seems to be the same on CentOS 6 and LinuxMint. Any idea
what may be going on?
Thanks.
Boris.
