Hi,

In RFC 793 page 45 ,[section OPEN second para] it is mentioned as :-

  If the active/passive flag is set to passive, then this is a
         call to LISTEN for an incoming connection.  A PASSIVE OPEN MAY
         HAVE EITHER A FULLY SPECIFIED FOREIGN SOCKET TO WAIT FOR A
         PARTICULAR CONNECTION

here comes my doubt:

(pls read the above BOLD letter lines) is there any real application which 
gives this type of calls?

i think iam clear

thanks

Regards,
Srinivas
