Problem: you have a netbook or laptop and need to switch network profiles (for example, wifi at home and at work/school) and you are a lazy ass who does not want to enter the passwords all the fucking time.
Solution: netpro - it lets you save and switch profiles. All interface profiles are saved in /etc/network/ and not readable as normal user.

Code: Select all

#!/bin/bash
ROOT_UID=0
if [ "$UID" -ne "$ROOT_UID" ]
then
  echo "You must be root to run this script."
  exit 87
fi

saveprofile()
{
	echo "Enter name for profile: "
	read proname
	echo
	echo "Saved as /etc/network/net.$proname"
	cp /etc/network/interfaces /etc/network/net.$proname
}

loadprofile()
{
	ls /etc/network/net.*
	echo "Enter net. profile to load without prefix: "
	read proname
	echo
	cp /etc/network/interfaces /etc/network/interfaces.backup
	echo "Current profile saved as /etc/network/interfaces.backup"
	cp /etc/network/net.$proname /etc/network/interfaces
	# The next lines are optional, they automatically restart the active interface.
	# snip ------------------------------------
	iface=$(cat /etc/network/interfaces |grep iface|cut -d" " -f2|sed 's/lo//g')
	echo "$proname loaded! Restarting $iface"
	ifdown $iface
	ifup $iface
	# ------------------------------------ snap
}

editprofile()
{
	nano /etc/network/interfaces
}

echo "[s]ave current network profile as ..."
echo "[l]oad profile from list"
echo "[e]dit current interfaces file"
echo "[q]uit"

read -n1 -s sel

if [ $sel = 's' ]; then
	saveprofile
elif [ $sel = 'l' ]; then
	loadprofile
elif [ $sel = 'q' ]; then
	exit 0
elif [ $sel = 'e' ]; then
	editprofile
fi

for the even more lazy+

Oh right, please test if it works for you. Thanks ;)

Posted: **Fri Apr 18, 2014 5:26 pm**

This is not much of a test, but at least it shows the correct stuff for the network I am on.
I don't have any other networks to connect to, at the moment.

Posted: **Fri Apr 18, 2014 6:18 pm**

Nice, very nice.

Posted: **Sat Apr 19, 2014 7:00 pm**

Very handy indeed!
Will test, this is what I spend a lot of time doing, go to work - change wifi, go home, change wifi... go home, home- change wifi.

Posted: **Wed Apr 30, 2014 9:00 pm**

I forgot... to post that this works *perfectly*, hot swapping from work, to home, my flat, on the road.
For convenience I've, aliased the 'sudo' line and put into the sudoers file there's no password needed.
even works for my phone hotspot function, excellent work.

That's great to know, thanks wux. I tried it on two PCs with 3 different locations and it does work for me, too.

Posted: **Wed May 21, 2014 10:38 am**

It currently holds:
work, home, home2, home3, on-call flat, and the phone.
The sudoers trick makes it nice and quick.
Now, if one could pass it the saved name as an argument, that would be ultra sweet (and I suppose even xkeybound?) 8)

not related to your script, but I though ceni was supposed to support this 'roaming' - I never got it to work, surprise... 8)

Posted: **Wed May 21, 2014 1:29 pm**

oh that would be nice indeed. I look into it...

All my own work *zazehem* - hmm might look into getting it to read the conf as an argument, now I more or less understand the layout.

Posted: **Wed Dec 10, 2014 4:47 pm**

completely forgot about this one... I'll do something that reads the conf without looking at your version, and then we compare penis length :D

Heh, not a problem, works perfectly well right now, I was bored and decided to rainbow it clean the presets and just /dev/null the output, just ricing :)

It's dirty and nasty and doesn't reuse code, doesn't check to see if your $filename exists, however although a bit messy looking because bacon coded the original so robustly, it doesn't matter; just loads the backup or something :)
So anyway now it accepts command line config:

Oh nice, thanks, it does what it should do!

Posted: **Tue Apr 21, 2015 10:29 am**

well you are welcome :) I just bolted on a variable and reused your code.
I only move around a few places, so makes sense to pass an argument.
Was thinking of bloating it to grep the wifi SSID's available on 'resuming' then pass that to connect. then a fancy icon, then a signal strength... ten... I stopped myself :)

Posted: **Tue Apr 21, 2015 12:53 pm**

Well, there are some points to improve or change or worsen, as long as it does what its user wants it to do, it's OK :D and yes, we could have an icon/applet for it - provided we want to have GTK2 dependencies. :) Nice little exercise.

I would like to get this roam, I think that would be nice. not 100% sure how though

I appreciate your rainbow terminal ricing, and also
