Do anyone out there know the differences between the BSD socket and
the socket stuff on HP 9000/320 running HP-UX 5.17 ?
According to the manual pages, it seems to me that they are the same, but
when I try to install some software which use socket to communicate between
an HP and another machine running XENIX (3.4), it fails (It works between
VAX BSD 4.3 and XENIX).
Any hint will be appreciated. Thanks in advance.

Can you be more precise as to what did not work?

The problem occurs when two processes on the HP try to communicate with each other by socket (NOT between the HP and the intel System 310 :-), actually the connection between the HP and the intel System 310 is successful). dsoc = socket(AF_INET,SOCK_STREAM,0); ... setsockopt(dsoc, SOL_SOCKET, SO_REUSEADDR,...); ... connect(dsoc, (struct *)&his_addr, sizeof(his_addr)); ... but the connection fails. The errno tells me "Connection refused". But the same code works on the VAX BSD 4.3, any clues ? 'Kong UUCP : ..!{sdcrdcf,ihnp4,cepu,trwspp,ucbvax}!ucla-cs!kong ARPA : kong@cs.ucla.edu

The errno tells me "Connection refused". >But the same code works on the VAX BSD 4.3, any clues ? I assume the peer process did a corresponding socket(), bind(), listen(), accept() sequence. By the way, why do you do a setsockopt() on the connect socket? You normally do it on the bind socket. Unless there's a reason for it, remove it. Anyway, that errno tells me that the server wasn't listening on the particular port you were trying to connect to. After you've started the server process, do a "netstat -a" to see if it's there. Make sure that the port and address in the "his_addr" struct are correct. ...tai
