Description ZMo 2011-12-05 10:19:03 UTC

If you test an open port with "nc -w <n> <host> <openport>" the timeout works and after the amount of time specified with "-w" option, nc will terminate; doing the same on a no exposed port, timeout wont take effect and nc will stay appended forever. 

Version-Release number of selected component (if applicable):
nc-1.100-3

How reproducible:
100%

Steps to Reproduce:
1.Install nc 1.100-3 (yum install nc)
2. nc -w 2 <host> 65525



NOTE: It seems to be the same on Fc16 with nc-1.101-3.fc16.x86_64.rpm

Comment 1 Petr Šabata 2011-12-21 15:37:43 UTC

The '-w' option in pre-1.103 versions is not about connection timeout.  See nc(1) for details.

This is 'fixed' in 1.103+ releases, available in Rawhide.
