Hi,

some time ago I asked similar question. Now I got some clues how to do this properly, but I can't find any decent docs or tutorials on this matter in Perl.

I want to write TCP client, that will automatically maintaint TCP socket to server and reconnect if necessary...

I got following sockopt options to use:

#KeepAlive<br>
setsockopt($sck,SOL_SOCKET, SO_KEEPALIVE, pack("l", 1));
<br>
#After 30 secs idle send KeepAlive probe<br>
setsockopt($sck,IPPROTO_TCP,TCP_KEEPIDLE, pack("l", 30));
 <br>
#Rest probes after 30 secs.<br>
setsockopt($sck,IPPROTO_TCP,TCP_KEEPINTVL,pack("l", 30));
 <br><br>

Now I have no clue how to include this in Perl program - do I have to write in event-driven manner or just collect state of socket in ordinary manner. I'd just like a program that will reconnect/maintain socket connection (with those socket options)and will not loose data sent to tcp connection - will continue only if write was succesful and rewrite on broken socket ...

I'd kindly ask for more info, pointers or working examples....

Thanks in advance,

Rob.
