LIVE600 - Telnet into an A600 from your browser

avantgarden · 25 April 2020, 18:43

Dear Amiga aficionados,
I'm new to this board (but I've been lurking for a while!), i hope not to break
any rules/conventions.

Would you please leave me a love message in a floppy?
By clicking here:

http://avantgarden.dyndns.org/amiga600/

you will "telnet into" an actual Amiga 600 and will be able to poke around!

(mobile browsing tested OK with Android 8+, Chrome and Firefox)

Have been working on this for a while...
Glad to give technical info on how to achieve this!
Thank you very much,
Avantgarden

**UPDATE**
I've added a rudimentary dial-up functionality!
It just displays a banner but hey, it is still an Amiga 600!
Click the link above and issue the "modem" command!

Pretty well protected! Nice. :-)

avantgarden · 25 April 2020, 20:38

Thanks for visiting me! Protection is never enough... Even if I get defaced I will learn something!

indigolemon · 25 April 2020, 20:55

PFS3 I assume?

avantgarden · 25 April 2020, 21:02

Eh eh! No, "telnet censoring"...

Retro1234 · 25 April 2020, 21:45

Brilliant ,Wish you were here.

avantgarden · 25 April 2020, 21:47

Thank you sir! Ummagumma

Some insights!

On a Raspberry Pi runs "Shellinabox" and a telnet proxy that blocks offensive commands.

The RPI is in between you and the actual Amiga [PS. added for clarity].

So nice to hear DFO: clicking when you leave a message!

Wished to use a plain Amiga 600 but had to add 1 MEG CHIP for this to be usable.

I've found the embeddable Topaz font on GitHub! https://github.com/rewtnull/amigafonts/

Cheers

So thats how your blocking the commands.
Very cool, as I tried using ed to look at some stuff and it didnt work.

avantgarden · 26 April 2020, 00:32

Hi Sneeker! Use "type" instead!
ED has a GUI.
Thanks for chiming in, cheers

Moar insights!

The "wall" command that broadcasts a message on all consoles is in fact a small BlitzBasic2
executable that connects to the standard Linux "wall" facility running on the Pi:

Code:

If NumPars=0
   NPrint "Are you scared to write on the wall?"
   End
EndIf

For i=1 To NumPars : wall$=wall$+Par$(i)+" " : Next
If OpenFile(0,"TCP:pi-address/pi-tcp-port")
   FileOutput 0
   NPrint wall$
   CloseFile 0
   DefaultOutput
Else
   NPrint "Unable to connect."
EndIf
End

On the Pi side "ncat" is listening!

Code:

ncat --sh-exec "/usr/bin/head -c80 | strings -n1 | /usr/bin/wall" --recv-only -l pi-tcp-port --keep-open

Many thanks to all the "beta-testers"!

I don't fully understand this but in theory could you LoadWb ?

avantgarden · 26 April 2020, 22:26

No sir, even Emacs doesn't work correctly! It's the aspect of the console that makes you want to "loadwb"! (fonts, colours). Try to toggle the "Purist" mode by clicking the right mouse button. Thank you.

So cool, loved it!

avantgarden · 27 April 2020, 14:09

Thanks for all the pentesting!! Lots of clever people around the board. I'll keep all those love messages in DF0: in my Amigan heart forever

. Stay tuned for mode technical insights for those interested. THANKS AGAIN.

Good evening my fellow Amigans.

For those who wondered what that strange S:ED.SERVICE script file is doing, more info can be found here:
http://aminet.net/package/comm/misc/Amied

I have a question for the kind user posting under the handle "Cobe", who connected from a mobile device: what version of Android are you running?

After a few more attempts with "hacking myself" I've found that:

5> SET a=reb
5> SET b=oot
5> $a$b

was indeed working, causing the system to reboot! Had to filter out the "$" character as a countermeasure.
With this trick, unlocking DH0 is trivial... Phew!

Thank you guys, you all rock!

Older versions (5 for example) made a real mess with the "Shellinabox" Ajax keyboard routines...

Sorry, the downtime is for setting up a 28.8 MODEM and AGetty!

http://aminet.net/package/comm/uucp/AGetty0_218

Is that all I need to get the Amiga "dialable"?

I'm testing from a 1200 with Terminus but BOTH phone lines are Voip...

A1200 --> MODEM --> ATA --> VOIP --> ATA --> MODEM --> A600

(ATA = analogue phone adapter)

Sigh! 1 call out of 10 I get the AGetty banner but characters aren't echoed back in Terminus.
Help needed from some BBS guru!

Cheers,
AvantGarden

avantgarden · 01 May 2020, 18:33

Fixed by forcing the calling modem to negotiate 1200 cps! The 600 is now officially DIALLABLE...
