[GemStone-Smalltalk] How to configure GS/S 6.1.2 through a firewall (blast from the past)

[James Foster]

Good work verifying that the initial connection from the GCI client to the NetLDI is working. Reading the error message more closely I see that the problem claims to be connecting to the stone. Are you doing a linked login or an RPC login? I think it will be much more difficult to do a linked login from outside a firewall. Can you start the NetLDI in debug mode (/d)? Can you track down the various log files? Is there a gemnetobject log file?

You need to have at least two ports open, one for the initial connection between the GCI client and the NetLDI process and one for the subsequent connection between the GCI client and the Gem launched by the NetLDI.

Note that you need to open this port on the firewall (and it is below the range you designated). When you initiate a connection from the GCI client, it needs to know the NetLDI port. If you provide a number, that is fine. If you provide a name, then it will do a lookup in the services file (C:\Windows\System32\drivers\etc\services) and use the number found there. If you do not have an entry for netldi61, then it will attempt the connection on a random port (not very helpful!). In your example it attempted a connection on 53695, indicating that you do not have the Windows client configured properly.

I’d suggest you start NetLDI on 10088 and use 10089:10089 as the secondary port range. Then open 10088 to 10089 on your firewall. Finally, on your client, add an entry to your services file or explicitly use 10088 instead of netldi61 as the service.
