Hai 

	We would like to seek the advise on two issues:

Problem 1:

	What is the bext way to handle errno 61 => ETIMEDOUT,

	error => connection timed out.

	At the present we are closing the socket and reopening if errno == 61.

	This also led to errno 48 and 54 which are 

#define EADDRINUSE      48              /* Address already in use */
#define ECONNRESET      54              /* Connection reset by peer */


	What are the several options available if one desires to send the 
message anyway!


	Simple sample code would help.
Problem 2:

        "gethostid" returns a "long", the id of the processor.

        "gethostbyname" returns a pointer to "struct hostent", with two fields
        of relevance => "h_addr" and "h_length"

	After an "accept" call, the address of the peer is placed in the
        sockaddr_in.sin_addr.s_addr field.

	1. Are the results returned by gethostid, gethostbyname and accept 
        calls compatible. 
	2. What are the necessary htonl, ntohs conversion 
	required. 
	3. Atleast in the AF_INET domain, can one assume that the
	host length will be == sizeof(long or u_long)?

	Simple sample code would help.

Thank you very much for your time.
