Bind returns -1

From man inet_addr :
The inet_addr() function converts ... If the input is invalid, INADDR_NONE (usually -1) is returned. This is an obsolete interface to inet_aton, it is obsolete because -1 is a valid address (255.255.255.255), and inet_aton provides a cleaner way to indicate error return.

Try also :

Code:

/* Listen on all interfaces */
my_addr.sin_addr.s_addr = htonl( INADDR_ANY );

[edit]

And your IP adress dynamicly assigned is certainly not 10.12.110.57 if adress assigned by your ISP, if LAN adress it may be the good one.

Why should I use aton() instead of inet_addr()?

nothing more than the manual

Part 2 of my ongoing struggle with learning socket programming --

Thanks to everyone that helped me with my bind() problem, now I've gotten to the connect chapter. and it appears that connect won't work, strerror says the connection was refused. So I guess I got the code right, except I was trying to connect to google.com on port 80, I used google's IP address and defined the port as 80, I don't know what's wrong.
