Purpose

To effective understand the some useful niping command to troubleshoot the network issue.

Overview

To help diagnose the network or measure network metrics you can test the connection using SAP's NIPING program. You can use NIPING to analyze the network connection between any two machines running SAP software.

NIPING Online help

Executing only "niping" will show online help as below:

Performing niping self test


Starting niping server on the host by cmd "niping -s"

Starting niping client from the front end by cmd " niping -c"

Connection test
Connect / Ping OS Level:
Check if the server is reachable, no data are written to the partner (Linux): niping -c -X9 -H <host> -s 3298

Connect / Ping Application Level:
To check whether a NI base application can be reached, use the extra option –X1 which sends a
NI_PONG
and expects a NI_PONG message (Linux): "niping -c -X1 -H <host>

Connect to Dispatcher:
Sometimes the connection test with the Ping/Pong message is not sufficient, because it is not clear if the
dispatcher is running on the other side or another program. With the option –X6 a invalid
message is sent to
the partner, the response will be checked against the expected error message from the dispatcher
(Linux): niping -c -X6 -H <host>

Other Tests
Hostname Lookup : niping -v -H <Host>

Service Name Lookup
Same as for Hostname Lookups (Linux): niping -v -H <host> -S sapmsEMR ;sapgw00 ;sapdp00

Local Interfaces
Print all interfaces which are handled as local by NI. This list of IP addresses is e.g. important for the
Gateway program (Linux):
