How to (ps)ping through ZPA

(Lisa Lorenzin) #1

We’ve seen several inquiries regarding how to test for reachability through ZPA, since ping (and ICMP in general) is not supported.

Windows users can use a Microsoft utility, PsPing, to achieve similar functionality over ZPA. PsPing is a sysinternals tool that displays connectivity to a resource (by FQDN) via TCP rather than ICMP:
C:\Users\LLorenzin>psping -t

TCP connect to
Infinite iterations (warmup 1) ping test:
Connecting to (warmup): from 0.36ms
Connecting to from 0.31ms
Connecting to from 0.32ms
Connecting to from 0.33ms
Connecting to from 0.31ms

Sent = 4, Received = 4, Lost = 0 (0% loss),
Minimum = 0.31ms, Maximum = 0.33ms, Average = 0.32ms

Please note that this should be used solely to check reachability, and not for performance - it doesn’t accurate reflect latency when used through ZPA.

Mac users, you can use netcat or TCPping to accomplish similar reachability testing…
