Hi Tobias--

     I'm using Nick Ager's instructions for installing GLASS on an EC2
instance[1]. I get the following when I try to connect to Gemstone from
the Pharo tools:

***

'Unable to create a GemStone session.
NetLDI service ''50377'' not found on node ''localhost'':
recv(7,0xfffd1b5e,6,0) failed with errno=111,ECONNREFUSED, Connection
was refused'

***

     Did Nick mean to cite a different port? Or is there something about
my configuration that I should change to use that port?


     thanks,

-C

Craig,

The first question is whether NetLDI is running on the server. When you are logged onto the server using ssh, what do you get from the following:
    gslist -cvl

This assumes that you have $GEMSTONE set correctly and $GEMSTONE/bin in the path.

Next, it appears that Nick's instructions intend for you to run GemTools on the server with an X Window tunnel to the client. Is that what you are doing?

Tobias' comments appear to me to suggest that he is running GemTools on the client. If you are doing that you need to make sure that the proper ports are open on your server's firewall. Nick's instructions provide for opening only SSH (22) and HTTP (80). If you plan to run a GCI client (such as GemTools) outside your server, then at least two additional ports need to be open. If you are using 50377 as the primary NetLDI port (gs64ldi in /etc/services), then I suggest starting NetLDI with -p 50378:50378 so that 50378 is the secondary port. You would then open both those ports on your firewall.
