Hi Karanbir,

Do you mean a unix socket? (that's a question asked out of ignorance on 
my behalf rather than a statement!). I think by default it was binding a 
unix socket but I didn't know how to configure it hence why I bound it 
to localhost/tcp:60000 - it was the only way I could figure out how to 
get it working (I don't really understand how unix sockets work).

Anyway, if you can point me in the right direction, I'm happy to try and 
can amend the article if you think it's better that way (maybe you could 
  also explain why unix sockets are preferable to a network socket - 
security maybe??)

Alternatively, you are more than welcome to jump in and amend the 
article as you see fit in true Wiki style :)

Regards,

Ned
