I just installed ESET Security Suite 4.0, and now PingPlotter (and/or MultiPing) won't work. What do I need to do to fix this?
There are several solutions to this problem. ESET doesn't like the extra 'padding' we send out in packets > 28 bytes, so you can change PingPlotter's (but not MultiPing's) packet size, or you can change ESET to not look for extra 'cargo'.
This is probably the best option, because it allows you to change settings in PingPlotter as needed to do better troubleshooting.
By default, PingPlotter sends 56 byte packets. ICMP packets only require 28 bytes, though. There is a solid reason for this - intermediate hops and the final destination respond back with the same packet size when using 56 byte packets, but different sizes with any other packet size.
ESET, though, doesn't like the extra bytes sent out, so it's blocking the outgoing packets. You can fix this pretty easily by changing to 28 byte packets.
Note: This option only works in PingPlotter.
Don't forget about this in the future if you want to change settings for troubleshooting, or if you create a different named configuration in PingPlotter Pro for some reason.
