Re: SOCKET Connect() connects but shouldn't.

Scott, thank you for helping me try to understand this.  I've posted the 
program code on midrange.com here: 
http://code.midrange.com/index.php?id=86383b016d

That's my entire program. I realize it's full of a lot of extraneous procedures 
that are not even used here, but I just copied your copy books in so I wouldn't 
miss anything.  The shotgun approach. 

I changed the socket(xxxx   call to use literals instead of the constants, even 
though I'm sure the constants were fine. BUt just to be sure you know.

If it makes any difference at all... I am connected to my iseries over a 
two-way  satellite using a satellite modem.  I don't know why that would matter 
but maybe direcway does some weird stuff there. 

I wish I had a dial up account somewhere so I could test this that way and see 
if I get the same results. That'd tell me for sure that's its something on my 
modem or network or connection that's causing the problem if the dial up 
worked. 

Thanks,

Dave Johnson

Can you please verify that you are, in fact, passing SOCK_STREAM for the 
2nd parameter (like you posted here).  If so, can you please verify that 
SOCK_STREAM is a constant, and it's value is 1.

If you passed SOCK_DGRAM, or set the value of SOCK_STREAM to 2, it would 
exhibit the exact behavior that you're describing, because when you issue 
a connect() on a UDP socket, all it does is set the "destination" address 
on future datagrams, it doesn't actually send anything at the time you run 
it, thus it would succeed but no connection would be made.

So please make absolutely sure that AF_INET=2, SOCK_STREAM=1 and 
IPPROTO_IP=0 in your definitions.


The only other thing is that you're calling a prototype called addrCvtr(), 
and I don't know what that does.  I've never heard of that before.  This 
API is not a standard sockets API (unless you've renamed it!) and can't be 
found by searching the Information Center's API finder.

I took your code, but changed addrCvtr() to inet_addr() and ran it, and it 
worked just fine for me.  (It gave me a -1 on the connect() call).

So, again, please:

a) Verify that AF_INET, SOCK_STREAM and IPPROTO_IP are set to the correct 
values.

b) Tell us what addrCvtr() is.
