Test connectivity to remote machine

[Former Member]

I have created a web service consumer proxy to call a web service on a remote host from our SAP machine. However, ICF in SAP tells me that the connection to that remote host has been refused, so there might be a problem with firewall in between.

To check that I would need to make a test-connection from the SAP host to the remote machine, on a specific TCP port. Usually I would do that via telnet on the shell, but I do not have a shell access to the SAP machine.

So my question: Is there a way within SAP to test the connection to a specific port on a remote host?

You might use sm49 to create a local command that you can execute to test a telnet.

Thanks. But does that work for interactive commands like Telnet as well?

Hi,

yes works fine.

If the port is closed

Trying...                                                                                                                                                                                                                                                      telnet: connect: A remote host refused an attempted connect operation.                                                                                                                                                                                         External program terminated with exit code 

If the Port is open

Trying...                                                                                                                                                                                                                                                      Connected to 127.0.0.1.                                                                                                                                                                                                                                        Escape character is '^]'.                                                                                                                                                                                                                                      Connection closed.
