Problem:  I have problems sending over SNPP (one-way or two-way)

 Response: Check if you have a messenger defined for the specific protocol. Please note that it makes a difference if you use SNPP-one-way or SNPP-two-way. They each need their own messenger. Please make also sure that the messenger is started and running - you can start and stop them in the "Services" menu.

 If you have verified the messenger, please check with your system administrator if you are behind a firewall. If so, have your administrator check the firewall settings. The ports 444 and 7777 have to be opened for "outgoing".

 You can check if you can connect to the carrier by pinging the carrier's hostname, e.g.

            ping snpp.Skytel.com

            ping snpp.airtouch.com

Also try to connect to the carrier using telnet, e.g.

            telnet snpp.Skytel.com 7777

            telnet snpp.Nextel.com 444

1. Open a DOS window - or from the Unix shell.

2. Type   telnet snpp.skytel.com 7777

3. A successful connection will show   220 Gateway Ready

4. Type page 9351500

5. Type message This is a test

6. Type send

7. Type quit to end this session.

Using telnet, you will see the IP address. If your DNS can't resolve the hostname, you can also try to connect by using the IP address directly.
