Hi there,
I have a problem with socket programing. I have a database server running over Windows XP, and 2 clients. One is a Unix Solaris machine, and the other is a LInux Debian.
I wrote the same C program for both clients, but get different results.
I created a TCP socket, put it in blocking mode and call 'connect'.
When the Linux client runs this code, the Windows server completes the
TCP hanshake with the client (It gets the SYN, answeres with SYN/ACK
and then the client sends an ACK).
Yet, when I run the same code from the Unix client, the call to 'connect'
results in the client sending the SYN packet, but it is ignored by the
server.
I run Wireshark sniffer at the server and saw that the SYN arrived.
Does anyone know what change should I make in my code, so it can be used
both by Linux and Unix?
When having network connection problems, first thing it to (temporarily) stop all firewalls to see if there's some firewall blocking requests. If this is the case, then start investigating on differences between the two clients you're using: are they connected to the server in the same way?
Are they in the same network? I mean, within the same IP address range? If not, maybe the server is bound to a specific address, other than 0.0.0.0?
