Hello Monks,

We've got Comcast (an american internet service provider) showing up today as I got bumped off twice today for no reason I can ascertain. The service had been spotty, so they recommended getting a new router, which we did. I don't want this "spottiness" to take over my wifi situation and look to the tools I have. Right now, these are mostly bash commands or scripts:

$ cat .bash_aliases 
alias pt='perltidy -i=2 -utf8 -b '
alias cx='chmod +x '
alias bounce='sudo service network-manager restart '
alias shh="nmcli networking off"
alias wake="nmcli networking on"
$ shh
$ wake
$ shh
$ wake
$

The script I use to show me what's happening with the system journal is:

#!/bin/bash

timename=$(date +"%m-%d-%Y_%H-%M-%S")
_out_fn=$timename.txt
echo "Time is $timename " >> $_out_fn
nmcli network off >> $_out_fn
nmcli network on >> $_out_fn
env | sort >> $_out_fn
sleep 40s
echo ---journal control---   >> $_out_fn
journalctl --since "1 minute ago"  >> $_out_fn
exit

My platform is

$ cat /etc/os-release
NAME="Ubuntu"
VERSION="18.04.2 LTS (Bionic Beaver)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 18.04.2 LTS"

, but I seek a solution that can port to strawberry perl (windows) if possible.

I would like to develop a perl-based tool that can discern whether I have a wifi connection that gets me to the internet. There must be any number of ways to do this.

Does one send out a request to some host name, which might be fine, until that host name doesn't want to answer what amounts to a ping?

Part of this software tool that I want to have would also tell me when the wireless goes out in a log. For this machine, I think I would grep events in journalctl. Might it be able to run as a daemon?It might retry the connection every minute or so.

I hope that we can work up a few solutions to compare and contrast. Thanks for your comment.
