Without seeing the program, it's hard to tell. I suspect that you have a
big-endian/little-endian problem. Try getting the addr with gethostbyname
or convert the ip-addr directly with inet_addr.

Subject: Socket question? Network unreachable
I have a simple socket program. I've compiled it with gcc on
Debian 1.1 (kernel 2.0.29) and Red Had (Biltmore 2.0.30) and I keep
getting Network is unreachable.
Running gdb reveals the connect call is not working.
After stepping over the connect, errno = 101. "Network is unreachable" is
displayed by perror and the program exits.
This is a small program that runs fine under SunOS 4.1.3. The only thing
I had to do to the program was change the include paths from sys/ to
linux/.
My Linux box IP 140.117.43.69
Netmask 255.255.224.0
Network 140.117.32.0
Broadcast 140.117.63.225
Can anyone give me a clue as to what the problem might be. I don't know
what
to look for at the moment. The only thing I can think of is the above IPs
are not correct. I can ping and telnet to the target which has the server
this
socket program is to connect to. I look in the arp table and it has a
complete
entry. Would arp be able to figure out everything if the above IPs we not
right?
Thanks in advance for any advice.
