we are running a Debian Server that needs to be a ping/host/iputils-scanner. Now we got the problem that server isn´t able to do as many pings per time limit that we need it to do. Basically the server is doing about 200-300 pings almost instantly and then slows down a lot speedwise to about 1 ping per second. We don´t know the reason for that, but the server is brand new so we guess that can probably only have something to do with the basic setup of the server (probably a limiting variable). The server shows the same behaviour with almost all iputils/dnsutils execs like ping, host, dig, traceroute, etc.
Now what would be your job is:
1) Find the reason for the delay
2) Fix the error
3) Tell us what you did, so we can do ourselves if the same prob occurs again
