How to run a Telnet test for the Port 25 & 110 or backup 2375 & 110 for Windows 2000 or XP Professional 

Answer

The IBM Sterling Network team supplies a password reference/Getting started card, that outlines several configuration values. In the Tables below, you only need to test out the Node that matches what is referred to on that reference/Getting started card, its unnecessary to test all the combinations below.

If using a LAN connection, proceed to step 1. If using a Dial-up connection, connect first then proceed to step 1.

1. From Windows, Click START > Run
2. Type: telnet
- To see what is typed, for Window 2000, type: SET LOCAL_ECHO
- To see what is typed, for Windows XP, type: SET LOCALECHO

4. Enter in the telnet command in this format: open <address> <port#> press Enter
(see below for address and port#)

For SMTP (Send) testing:
Example: open primary.us.globalec.com 25

Address Port Drop down value to use in Comm profile
primary.us.globalec.com 25 Dublin_Primary
primary.gts.globalec.com 25 Dublin2_Primary
primary.ca.globalec.com 25 Toronto_Primary

For POP3 (receive) side:

Address Port Drop down value to use in Comm profile
primary.us.globalec.com 110 Dublin_Primary
primary.gts.globalec.com 110 Dublin2_Primary
primary.ca.globalec.com 110 Toronto_Primary


Below is the list of responses. The top 3 are successful. The final illustration is a failure.
Address Port 25 Port 110
primary.us.globalec.com 220 gts.globalec.com COMMERCE:Exchange ESMTP/POP3 Server version 1.0 Ready +OK Welcome
primary.ca.globalec.com 220 tor1relaypri.ca.globalec.com ESMTP server (Post.Office v3.5.3 release 223 ID# 0-62611U1000L100S0V35) ready +OK Welcome
primary.gts.globalec.com 220 gts.globalec.com COMMERCE:Exchange ESMTP/POP3 Server version 1.0 Ready +OK Welcome
"Could not open connection to the host, on port 25: Connect failed"
** If the Telnet to the servers on Port 25 fail, there is an alternate port option of 2375 available. See below for this alternative syntax to test.

** There is not an alternative port option for receiving. Port 110 is the only POP3 (receive) port available. **

For SMTP (Send) side:
Example: open smtp2.us.globalec.com 2375

Address Port Drop down value to use in Comm profile
smtp2.us.globalec.com 2375 Dublin_Primary(Port 2375)
smtp2.gts.globalec.com 2375 2375Dublin2_Primary(Port 2375)
smtp2.ca.globalec.com 2375 2375Toronto_Primary(Port 2375)
For POP3 (receive) side:
Address Drop down value to use in Comm profile
primary.us.globalec.com 110 Dublin_Primary(Port 2375)
primary.gts.globalec.com 110 Dublin2_Primary(Port 2375)
primary.ca.globalec.com 110 Toronto_Primary(Port 2375)

Look for an 'OK'/'Ready response back from the server (node responses below)

Address Port 2375 Port 110
Dublin_Primary(Port 2375) 220 gts.globalec.com COMMERCE:Exchange ESMTP/POP3 Server version 1.0 ready +OK Welcome
Dublin2_Primary(Port 2375) 220 gts.globalec.com COMMERCE:Exchange ESMTP/POP3 Server version 1.0 ready +OK Welcome
Toronto_Primary(Port 2375) 220 tor1relaypri.ca.globalec.com ESMTP server (Post.Office v3.5.3 release 223 ID# 0-62611U1000L100S0V35) ready +OK Welcome
"Could not open connection to the host, on port 2375: Connect failed"

When the response is successful, select that address value for the Gentran:Director Communication Profile - NETWORK tab option. Save your work and attempt a communication effort to test this out.

If the test fails for both 25 and 2375 then check that a proxy server, a firewall, or the Internet Service Provider is not blocking the transmission. Contact your network administrator or Internet Service Provider for further assistance.
