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" |
** 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) |
| 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.
