The following four lines aren't necessary... the 'conn' parameter
initializes your 'goer' object directly via the above line. The steps
below are needed only for a server socket. A server socket's only
purpose is to accept connections and thus produce new sockets.

Also, the 'sock' argument above is confusing - it's actually the
server object (of class 'checker') from below, a better name for this
parameter might be 'server'. I think if you just remove the four
lines above it will work.
