I am using the not free Roadshow TCP/IP stack since it have builtin PPP support.
I tried with AmiTCP both latest stable and unstable, plus third party PPP and couldn’t get anything working properly.
Buy and install Roadshow and configure:
In the file
DEVS:NetInterfaces/PPP, change the two lines by:
Create the file
interface=ppp device=serial.device speed=19200 rtscts=no checkcarrier=no nullmodem=yes
Notes: you may need to use “baud” or “speed” in the last file, depending on the alignment of the moon, if you get a warning about unknown keyword, try the other one.
- 192.168.210.30 ip the ppp0 interface will get on linux side
- 192.168.210.251 ip the amiga will get
- 192.168.10.1 my linux-side router
- enp0s25 is my laptop ethernet connection to the LAN
- You can skip the whole iptable part if you don’t needs to access the LAN and internet from the amiga, it will have only access to the linux ip side
- beware that the two first iptables commands will DELETE ANY RULES
- debug will show verbose things
- nodetach if you want to run it in foreground

[Unit] Description=Start PPP for Amiga networking [Service] Type=simple ExecStart=/usr/sbin/pppd file /etc/ppp/peers/amiga [Install] WantedBy=multi-user.target
Then you can:
sudo systemctl daemon-reload sudo systemctl enable ppp-amiga sudo systemctl start ppp-amiga
Check that the following exists in
;BEGIN Roadshow if EXISTS S:Network-Startup Execute S:Network-Startup EndIf ;END Roadshow
amiga-ppp.sh on the linux side.
reset your amiga, pop a newshell and execute:
And you can leave that window aside and enjoy slow internet.
