I'm trying to use POE::Component::Client::TCP to simulate some telnet
sessions. I get a good connect (my connection callback is triggered,
and I can see the connection at the OS level), but I can't seem to send
any data.
I'm doing something like this:
my @sendthis ("username","password","command","exit");
$heap->->put (@sendthis);
But nothing seems to happen. Frankly, I'm confused as to how this could
work, since the heap is shared between sessions.
I've also tried using $poe_kernel->post, but I can't figure out what the
first parameter is supposed to be. I don't have the alias locally, and
I can't seem to extract the peer address from the args.
Any ideas?

This is odd. Each session is assigned its own heap, and it is passed
to your callbacks as $_[HEAP] (the HEAPth element of @_). If you find
that all your heaps are shared, then you may not be using the
component correctly. More could would provide valuable context here.

It would help to see just how you're doing this.

They are? Hmmm. I'm wondering if I'm not having some weird deal
where the sessions are getting the same ID.........Yep. $session->ID
are all reporting "2". Now I'm *really* confused. I'm definately
giving a distinct alias to each session "telnet_$hostname". Distinct
aliases were how I made P:C:SNMP give me distinct session IDs, but I'm
not sure what the mechanism is that assigns them.

I've abandonded this a bit to try to mix together a
Poe:Component:Telnet. I'm pretty close, but I seem to be having a
problem with the session ID. Go figure. The POE documentation isn't
making much sense to me, either.
More soon.
Thanks.
