[Vm-dev] Multiple images listening on same TCP port

[Adrian Lienhard]

Hi,

On the Mac VM, when starting a second image with the same VM as an  
already running image, the second image opens the same TCP ports as  
the first image.

It is easy to see this. Start image A and do:

s := Socket newTCP.
s listenOn: 7777.

as expected:

lsof -i | grep Squeak
Squeak    1747 adrian    9u  IPv4 0x9dafa68      0t0  TCP *:cbt (LISTEN)

Now, start image B (PID 1752).

lsof -i | grep Squeak
Squeak    1747 adrian    9u  IPv4 0x9dafa68      0t0  TCP *:cbt (LISTEN)
Squeak    1752 adrian    9u  IPv4 0x9dafa68      0t0  TCP *:cbt (LISTEN)

It will also listen on port 7777...

Is this a known limitation?

VM: 3.8.20beta1U
Image: any (tested with Squeak 3.9 and 3.10)

Cheers,
Adrian
