NPING

Command

NPING -- Send a Netrom echo request

Synopsis

NP[ing] <nodecall | nodealias> [bytes [secs]]

Description

The NPING command sends an NCMP (Network Control Message Protocol) echo request to the specified target system. If the target understands NCMP, a reply will be returned, allowing the round-trip-time and number of hops to be determined. It is intended mainly as a network diagnostic.

Options

The command allows the user to specify an additional data payload, and an interval between pings. This can be used to assess the consistency of link performance.

Examples

nping gb7gc
G8PZT:KIDDER} NPING: hit <RETURN> to quit...

Pinging gb7gc with 0 bytes of data:

GB7GC: echo reply - rtt 17985 msec, 3 hop(s)


nping  gb7gc 10 20
G8PZT:KIDDER} NPING: hit <RETURN> to quit...

Pinging gb7gc with 10 bytes of data:

Target             Interval   Sent   Rcvd   %  Ave Rtt
GB7GC                 20020      1      1  100 5170
GB7GC                 20020      2      2  100 6930
GB7GC                 20020      3      3  100 6765

Limitations

NCMP is under development and is currently implemented only in XRouter / XRPi, so you can only NPING another Xrouter at present.

Availability
