Default Sharing an internet connection over serial cable

The topic says it all really. I assume its possible to do, but I have no idea how to do it. Any advice would be greatly appreciated. Thanks. Oh yeah, incase it's necessary to know the machine that's connected to the net is a windows machine and it's OS3.9 that Im trying to get online via serial cable.

Can you not get a proper NIC? Seriously.

Default Re: Sharing an internet connection over serial cable

I would be interested in a solution to this problem also, as there is no other way to go online from a CD32 and I would love to have my CD32 on the network as well.

Hello. Half-way off-topic reply: for Unix/Linux + Amiga there is Mlink (Multilink)
At aminet: http://aminet.net/package/comm/net/mlink132
If you have some extra linux pc for this you could use it between Amiga and the windows PC.

I used Multilink with a 500 a while back and it works well.

Worth a shot. Now the initial response will probably be that he said he has a Windows machine, not Linux, so how would he get the needed "unix" shell account multilink needs?

All he needs is a small Linux VM running under VMWare (or one of the other virtualizers) on his windows machine.

I haven't used that multilink, but I think I'll look into it myself, as I have lots of Linux running already.

There was a slirp client for the Amiga that worked with a Windows host. Mind you, I last used that in 1995 :-)

Default Re: Sharing an internet connection over serial cable

I run Linux (and not Windows) on the laptop here so Multilink might just be the thing for me too. Now I just need one of those USB-Serial adapters.

Default Re: Sharing an internet connection over serial cable

There is the recipe for connecting an a600 to the net over a serial link:

Ingredients:
- A fonera 2.0g router (in developer mode)
- A serial to USB adapter and the corresponding module (driver).
- Extra slip module for the fonera (compiled by me).
- Some slip tools & scripts for the fonera (compiled and wrote by me).
- Some extra iptables rules for the fonera's firewall (added by me, included on the scripts above).
- A null modem cable.
- An unexpanded Amiga 600. I've installed a 64Mb CF as HD, but you can built It from floppies.
- Workbench 2.x+
- AmiTCP 4 (demo version, of course).
- If you want a webserver, add the arexxwebserver package...

Preparation:
- Plug all cables and machines together.
(fonera usb port<---> USB to serial dongle <---> Null modem cable <---> Amiga 600 serial port)
- Turn on the machines.
- Install all the stuff into the fonera and restart It.
- Run Workbench.
- Install and configure AmiTCP to match your network settings using slip protocol.
- Configure arexxwebserver if you want It
- Run AmiTCP.



That's what I did, and It works like a charm.
Of course, It's very sloooooooooooooow... But I's amazing what you can do with a 1Mb Chip Ram machine.
Now you can do networking betwen your slip machine (the amiga) and your wired and wifi machines, and/or internet too...

The only advice:
The most reliable speed I got with serial.device was 9600 bps. You can use 19200 bps if you want, but you'll lose a lot of packets (about 25% on my tests).
You can use also cslip instead of plain slip, but It gives no much speed increase, and a bit more of cpu power load...

Extra tip:
Baudrate: 9600, hardware handsake (7 wires or CTS/RTS)
MTU: 576

I'll post all the details later (I'm at work now).

Cammy, What distro do you use?
I can help you to configure your linux machine.
It's easy: You only need to include the slip support into the kernel (if you haven't It), as a module or recompiling It (the kernel).
After that, you only need to run slattach and bring up the interface.
Denpending on your distro, you'll need some routing and iptables rules too.
Of course, you must do It with the USB to Serial adapter plugged in and the null modem cable between It and your amiga :P
On the amiga side, you only need AmiTCP.
If you need more details, please send me a PM.

Hey, here comes a little demo:

http://ferix.no-ip.org:2080

Please, be patient. Remember It's connected over a 9600bps link...

If you can't view It, please try later. It only serves one page at time (a memory restriction).

Default Re: Sharing an internet connection over serial cable

Hi Ferix, thanks for the quick guide and offer to help! At the moment I don't have a USB-Serial adapter yet, but I'm going to order some from DealExtreme. When they arrive I'd very much like to work out how to do this, mainly so I can get the CD32 online. Hopefully the connection to the net won't be too slow for me to play Dynamite, but I have a feeling it may be. I have Ubuntu on the laptop.

Your site is cute, just like the A600. It was nice to see it loading up from there.
