Configuring a better busybox

[knc1]

This finding a way to make a new version of busybox run, even with the old one still installed, is a great find.

Not sure what good having a tftp server on a Kindle is.

Well, if anyone ever asks how to network boot their desktop from their e-book, we are ready.

[twobob]

well. I kid you not - it took me 30 mins to boot my windows laptop and install telnet.
I have witnesses - but all that aside : ) it sure is nice to just jump into the device from anywhere now.

[twobob]

Ah having a further look this appears to be Nilujes doing.

: ) no surprise there. It's referencing a third copy of busybox

well back to what I was doing then

@twobob: Yes, usbnet launches a telnetd alongside dropbear/openssh on the K2/K3/K4 . (It's actually the telnetd busybox applet (launched standalone, no inetd), with a patched login applet to allow passwordless logins. Hence why it's disabled when the wifi setting is enabled in usbnet, to avoid leaving a huge backdoor open to the four winds ).

[twobob]

Yeah I remember reading your notes on that. now. and indeed have just parsed every single line of readable code you left on the machine in /etc /mnt/us/usbnet and otherwise.

call me anal. Don't enjoy mystery's as much as solving them : ) Yeepee!!!

[knc1]

I read that stuff also. And forgot it, also.
Darn, the story I made up sounded so good.

Doing development in public means making mistakes in public.
Perhaps someone else will be saved the time and trouble of repeating our mistakes.

[twobob]

Thats exactly what I thought mate. I genuinely no longer mind making totally blindingly huge gaffs. If SOMEONE had taken the time to do them before me I could read those threads instead.

What actually happens is single posts included one perfectly manicured software offering. Zero clue as to how or why. So yeah, "Go Us" for being the ones who step in the stuff on the sidewalk. In this way, we share what we have learned, better than any single piece of software.

Ash honours this. and a strace confirms that it now reads /home/root/.bashrc

Setting ENV in a .bashrc has it's drawbacks as it will be processed twice.

So - more sensibly - we should probably just set the ENV value at boot to another filename and populate that with the current current .bashrc noise.

Anyways - that is by the by and will be decided in the wash.

Here are some tests.
....

Re this: su -c 'su -v' -l will only work if the ENV AND the .basrc are processed... I.E same data twice.

So to this end I recommend doing that until a better option comes along.

vi !:command also honours this so, yeah.

Word to the wise and all that.

also tried just dumping the new Busybox binary as a straight replacement in /bin

Wifi didn't work so I obviously missed some support somewhere.
However the replacement functions via the alias method work so well I don't think I will bother fixing it.
