[PLUG] How to detect ppp address change remotely?

[Martin A. Brown]

Hello,

 : Only have busybox on these devices. Unfortunately -T isn't 
 : supported, and tcptraceroute isn't installed.

Sounds like a very messy all around, but if you are trying to find 
the IP path, consider both your old friend traceroute and maybe the 
little-known 'record-route' IP option which can be returned by ping.

  # -- no name lookups, use the 'record route' option
  #
  ping -nR -- "$IP"

  # -- no name lookups, use ICMP, send 10 packets immediately
  #
  traceroute -nIN 10 -- "$IP"

Good luck,

-Martin
