As an addition to this message, how would one do the following?
When one connects to a remote IP address, we get a local port number as well
as a remote port number. How do I find out what the local port number is?
For example:
>> z: open tcp://192.168.0.1:21
>> probe z
make object! [
scheme: tcp
host: 192.168.0.1
port-id: 21
user: none
pass: none
target: none
path: none
proxy: none
access: none
allow: none
buffer-size: none
limit: none
handler: none
status: none
size: none
date: none
url: none
sub-port: none
locals: none
state:
make object! [
flags: 524819
misc: 80
tail: 0
num: 0
with: "^M^/"
custom: none
index: 0
func: 3
fpos: 0
inBuffer: none
outBuffer: none
]
timeout: none
]
We know we are connected to remote port 21, and we know by my netstat that:
Active Connections
Proto Local Address Foreign Address State
...stuff...
TCP davids:4403 server:ftp ESTABLISHED
...stuff...
How would I know what my local port is? z/port-id appears to be the remote
port when you open one, or the local port if you specify "tcp://".

It is in the "how-to", under "Opening an Listen Port"
but I didn't see it mentioned in the other docs.
