From a54e58b4d6bc5f6eabe161fbdc0709dfadd69189 Mon Sep 17 00:00:00 2001 From: Matthew Nickson Date: Thu, 14 Jul 2022 08:32:51 +0100 Subject: [PATCH 2/6] Added Ping packet size #1891 This should fully implement #1891 by adding an extra field to the edit monitor page and an extra column to the database. The user can now set the size of the packet to send, it defaults to 56. A maximum limit of 65500 was chosen to ensure that the total size of the packet does not exceed the IPv4 maximum packet size and to comply with the limit imposed by Windows.
