Hi

I'm trying to use a Python script from Git "https://github.com/PaesslerAG/QoSReflect/blob/master/qosreflect.py#L1"

Its purpose is to respond to monitoring packets sent from PRTG Network Monitor

So I downloaded it and chmoded it and executed it (-d) on
the client's Debian system :

Linux xxxxxxxxx 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux

and obtain the following error :

Bind failed. Error Code : -2 Message Name or service not known

The error apparently appears when the bind action attempts to
bind port 50000 to all devices

Is this a Debian, or system issue or a permissions issue ?

thanks
yann

You downloaded a script off the internet and ran it on a client's system?

Yes

I figured it out : HOST is supposed to be the network interface's IP address
