[DGD]Ping ?

[Tavis Elliott]

The easiest way to do this is to log into a shell account on your
application's host machine while the "lag" is happening, and run 'ping'
(after you've obtained the user's IP address).  If the user is behind a
firewall this may not work.

If you want to do this from the application, you'll have to actually
implement some form of a "ping" in LPC using the network package, or find an
existing implementation of ping in C and merge it into the DGD source.
(Again, if the user is behind a firewall, this may not work)

If your ultimate goal is to try to have the application react to a user's
"lag", it is my understanding that the ping approach is not reliable.  Ping
uses ICMP, which could very well take a different route to get to your
machine than the player's TCP/IP data.  ICMP packets might also have
different priorities on routers along the way, even if they do take the same
route.

Hope this helps!

  Some of my users said that they were experiencing some SERIOUS lag/delay
when connected to my DGD based application.  How can i verify that ? is
there a way to ping them ? I verified in the kfun and didn't find anything
usefull (except maybe for ctime and time...)

  I'll be glad if someone tell me what to do...
