Hi Folks, I'm just getting into ASIO, and am having problems with the examples. I'm trying out both the tcp::iostream examples and the (more basic?) synchronous TCP daytime clients in the tutorial. I have the server print the socket endpoint, which produces: 0.0.0.0:23421 (23421 being a randomly typed socket number, once I figured out that the '13' in the examples doesn't work because Linux reserves socket numbers up to 1024 for the kernel). I then run the client, providing 0.0.0.0:23421 on the commandline as the address to connect to. I get this: Host not found (authoritative) Does anyone know what that means? I know very little (read:nothing) about the tcp protocol, which is probably the real problem. :-) Thanks -- Dave Steffen Numerica Corporation (www.numerica.us http://www.numerica.us/ ) 4850 Hahns Peak Drive, Suite 200 Loveland, Colorado 80538 main (970) 461-2000 direct (970) 461-2422 x227 fax (970) 461-2004 Email: dave.steffen@numerica.us
