inspectsocks  can   be used to determine the SOCKS version that a server supports.  Inspectsocks takes as
       its  arguments  the  ip address/hostname  of  the  SOCKS  server  and  optionally  the  port  number  for
       socks.  It then  inspects  that  server to attempt to determine the version that server supports.
       Example:
       "inspectsocks  socks.nec.com  1080" -- attempts to determine the version that the server supports
