IO::Socket::INET: connect: Permission denied

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I'm trying to open UDP listener on local machine, but get this weird error :

 
Wed, 26/09/2012 04:59:15.728  CYBRO: ****** ERROR ******** Can't make 
+UDP socket listener: IO::Socket::INET: connect: Permission denied
Wed, 26/09/2012 04:59:45.728  CYBRO: ****** ERROR ******** Can't make 
+UDP receiver  on 192.168.0.255 and port 8442, retrying
[download]

Using nmap port is not used, so I really don't understand what is wrong. I'm running code as root :

$self->{Abus_udp_receiver}=IO::Socket::INET->new(Proto=>"udp",LocalPor
+t=>$port,Reuse => 1, PeerAddr=>$udp_listen_url, PeerPort=>$port ) or 
+runlog ($self,"****** ERROR ******** Can't make UDP socket listener: 
+$@");

What is wrong ? Thanks in advance, Robert.

this code worked on previous systems. I recently upgraded to Ubuntu 12.04 and maybe seems to me machine configuration issue. try turning off firewall.	[reply]

permission denied is a weird error?	[reply]

permission denied is a weird error? Not weird but I suspect Security-enhanced Linux (SELinux) is enabled and affecting socket connection on this machine. Disable SELinux if enabled and give a try.	[reply]
