I was playing around with this option to use multiply socket connections with same hostname and same port (IRC). However the socket function needed for this is SO_REUSEPORT.
Though the majority of linux distro's does not have that yet officially implented in there distro's.
However for debian there is an patch that can be installed to get it working:
it has some work but I got it working after a while (Noobie in debian) maybe some other people are facing the same problem as I was.
