UDP example client does not start

[Stefan]

I am currently playing with UDP (no experience with it yet). For getting things started I tried the example udp client and server from http://www.newlisp.org/CodePatterns.html#toc-13">//http://www.newlisp.org/CodePatterns.html#toc-13 .

Server started, but the client reports an error:

Code Select Expand


newLISP v.10.6.0 64-bit on OSX IPv4/6 UTF-8 libffi, options: newlisp -h
> (load "udp-client.lsp")
(10 "Cannot bind socket")
nil


Something I forgot?

Probably the port 10002 is in use by an other program. You could try changing port numbers in both the server and client programs. For port numbers < 1024 you need admin permissions.





Ps: Also note, that on Windows the programs udp-server.lsp and udp-client.lsp from the newlisp-x.x.x/examples directory should be used for a different format of address strings. The snippets in CodePatterns.html are only for Unix. The examples in CodePatterns.html have now been changed to work on all platforms.

Yep, that's the reason.



Thanks,

Stefan
