Hi, Thanks for your great module, it is really cool. However, I experienced a problem - the event loop is waiting infinitely when network disconnected. Code: http://pastebin.com/nXjDRk9H You can see, I put a line: system(" sudo /etc/init.d/networking stop "); in the code, so to simulate network disconnected. I found no way to escape from this timeout, is it possible to specify a max. timeout so my program won't be waiting forever? (Quite from event loop is ok for me)

You really should be getting a socket error event at some point. I can't really test this currently ( ie. disabling the network ). If you could enable the POE tracing whilst running the script and send me the results ( bingos@cpan.org ), that would be great. to enable POE tracing just set the POE_TRACE_DEFAULT environment variable. It'll spew a load of output to stderr as I recall. Many thanks. -- Chris Williams aka BinGOs PGP ID 0x4658671F http://www.gumbynet.org.uk ==========================

I have sent the debug log to bingos@cpan.org, please let me know if you haven't receive it so I can send again. Thanks.

Hi, I've just uploaded version 2.18 of the module to CPAN. It now has a TimeOut option to spawn() so that one may specify a delay, in seconds, between sending a command to the server and receiving a response. If no response is received within the timeout then the connection to the server is terminated and a 'nntp_disconnected' event will be triggered. Hope this helps and sorry about the delay (no pun intended). Cheers.
