Socket Problem
Hi all,
I have developed server/client application (using C) and tested it on the same machine .. but when I deploy them on different machines I get connection timeout.
Well .. server machine and client machine exists on different network segments, so there is a linux firewall box to route traffic (all ports are open on it)
so my question is there anyway that client program can communicate with my server program via the firewall .. is there any function in C for this kind of setup
(I searched alot but didn't find anything useful .. so If it is not possible .. how come there exists so many server/client application that can communicate via firewalls)

Can anyone help? I'm trying to write a program which will write to a socket. I can get the server to run, but always get an error when I try to connect.
It gives me an error at the "connect" command.
It's probably a simple error, but I can't seem to find it.

YPSET(8) BSD System Manager's Manual YPSET(8)
NAME
ypset -- tell ypbind(8) which NIS server process to use
SYNOPSIS
ypset [-h host] [-d domain] server
DESCRIPTION
ypset tells the ypbind(8) process on the current machine which NIS server process to communicate with. If server is down or is not running a
NIS server process, it is not discovered until a NIS client process attempts to access a NIS map, at which time ypbind(8) tests the binding
and takes appropriate action.
ypset is most useful for binding a NIS client that is not on the same broadcast network as the closest NIS server, but can also be used for
debugging a local network's NIS configuration, testing specific NIS client programs, or binding to a specific server when there are many
servers on the local network supplying NIS maps.
The options are as follows:
-h host
Set the NIS binding on host instead of the local machine.
-d domain
Use the NIS domain domain instead of the default domain as returned by domainname(1).

domainname(1), ypcat(1), ypmatch(1), ypwhich(1), nis(8), ypbind(8), yppoll(8)
