Hello,

I tried to connect tcl to a socket on another host.
When I was doing it from the same host there was no problem.
But trying from another host, I get the error:
Error: Couldn't open socket: connection refused.
Is this a bug or have I done something wrong?:
socket $kernel_host $WRITE_SOCKET

Thanks,
Sven

There must be something wrong between the two machines.
You are receiving a TCP level error that Tcl is reporting
back to you. Can you telnet to that port from that
machine, or use some other tool to access the open port?

Yes, I already tried to use telnet. I was to able to connect to that
port in this way.
On the other side is my C-program which I could verify that it was
listening to this port.
By the way I'm using Linux on the local and Solaris on the remote
machine.

Be sure that there isn't any firewall between hosts.

I'm still a little mystified, because people use ::http::geturl
all the time, which is essentially Tcl connecting to a web server,
most likely written in C (unless its tclhttpd) without problem.
Are there really no other routing anomalies for these machines?
