Re: socket question

Perhaps somebody can help me understand this behavior..

On host1 inside the tcl shell I type

set s [socket -async host1 19000]

I get an error "couldn't open socket: connection refused". This I
expected
as I have no server listening on host1:19000

On host2 inside the tcl shell I type

set s [socket -async host1 19000]

and I get "sock5". There is still no server listening on host1:19000,
and so I'm
wondering why on host2 I don't get the "couldn't open socket:
connection refused" message?

With -async you should attach a writable event handler and then check
the socket status when that is called. If a socket fails to open then
it becomes writable and you can check the -error channel configuration
to see how it went.

Are these systems different operating systems? I'm somewhat surprised
you got an immediate failure on one system. I would have expected to
get a socket both times and an error set on the socket channel in the
fileevent.

The wiki has some examples of [fileevent $sock writable]
