Bind failure
Hi all,
I am using Perl program to do socket communication. My application has to use port 40001 this is a condition I can't change the port.
The execution of this script always gave an error 'Bind failure port already in use'
netstat execution gives below line:
udp 0 0 *.40001 *.*
What this line indicates. I think due this port engagement bind fails. To fix this issue I used port reuse option as below before bind but still bind gives the same error:
setsockopt($serv_sock, IPPROTO_UDP, SO_REUSEADDR, pack("l", 1)) || die "setsockopt: $!";
How can I disengage the port binding?
Please help me in this regard...
Thanks...
