The trailing '=' is from the classify flag (-F) of ls.  Some login shells 
alias ls to include the -F flag by default.  You're probably more used to 
seeing -F append things like '/' for a directory.

As a socket, you should be able to see it with netstat.  You should be 
able to write to it via telnet to the port on localhost, assuming that 
netstat shows it's listening there and your firewall rules allow it.
