Hardware and connectivity

Out of the box Amix only supports the Commodore A2065 Ethernet adapter (full-length Zorro expansion card from 1990).

With the Gateway UNIX CD's (520 MB) drivers the Village Tronic's Ariadne card also works. The Ariadne is also claimed to be 20% faster in receiving than the A2065 (presumably under AmigaOS).

The A2065 only has a BNC (coaxial 10Base2) and an DB15 (AUI) ports. If you buy an AUI Transceiver and plug it into the AUI port, you can have RJ45 connectivity. Ardiane, being four years newer, has RJ45 on board making it easier to plug in into modern networks. Modern switches might however have issues with either board negotiating the port speed to old 10Mbps. If you have issues, you might need to set the switch ports manually or use an older 10/100Mbps hub or switch in-between.

If you're into vintage networking you can also go ahead and build your own coaxial 10Base2 network! Old 10BaseT (RJ45) hubs often have an uplink port with BNC (coaxial), or you can buy media converter for BNC-to-RJ45 conversion. Old ethernet gear is usually readily available on eBay (but not always cheap).

Basic installation

During the installation, you are asked if you want to configure network. Same can be done later in amixadm, it will ask you to give IP addresses and host names of the local machine and a remote machine (anything in your local network, this will be put to /etc/hosts). The IP address set here will be the IP address the machine will take during booting.

You can check the status of the network and the currently used IP address with ifconfig aen0

DNS

Out of the box, Amiga UNIX doesn't do DNS lookups but looks at local files (/etc/hosts) only.

To enable DNS access:

ln -f /usr/lib/libsockdns.so /usr/lib/libsocket.so
mv /etc/netconfig /etc/netconfig.TCP
ln -f /etc/netconfig.DNS /etc/netconfig

If you put your nameserver into /etc/resolv.conf this will get DNS working for at least some applications, like ping. Others such as nslookup appear to expect a nameserver to be running on the local system.

To easily configure your system, download couple of config files from here: amix_dns.zip

Place named.boot in /etc, and everything else into /var/named. Edit /etc/named.boot and replace the IP address on this line with the DNS server you use for your net connection:

forwarders 192.168.1.1

Then start named by running in.named with no arguments. Edit the file /etc/resolv.conf to contain this line:

nameserver 127.0.0.1

You can verify this is working by using nslookup to find google.com's IP:

nslookup www.google.com
Server:  localhost
Address:  127.0.0.1

Non-authoritative answer:
Name:    www.l.google.com
Address:  74.125.67.147
Aliases:  www.google.com

You've now got DNS working as well as I can get it to work, currently.

Routing

The route is set in the file /etc/inet/rc.inet. Assuming your gateway is 192.168.1.1, you need to add the following to this file:

/usr/sbin/route add default 192.168.1.1 1

Don't forget the extra “1” at the end, that's the metric and it's required.

Remote connections

You can remotely log in into the Amix system by using rlogin or telnet and the IP address of the machine: rlogin 192.168.0.44 telnet 192.168.0.44

If backspace doesn't work over the remote session (produces chracaters instead of deleting), fix it by typing stty erase (backspace)

General weirdness

Oh yeah, there's some weirdness for sure. One thing: leave your domain unset, or set it to “nodomain”. If it is “properly” set, it appends your domain to every lookup request for at least the ping utility. The file to edit is /etc/domain. You can unset your domain without a reboot by executing:

domainname nodomain

Installing drivers for Village Tronic's Ariadne card

Copied for safekeeping from eab.abime.net discussion by vintageBytes

Download and copy the drivers to the Amix machine.

  • Log in as root user.
  • Copy the install.ariadne script to / and execute it: sh install.ariadne The script can throw a few warnings, normally these are only for file permissions and can be ignored as you are logged in as root.
  • After the script execution you need to compile a new kernel. So type: cd /usr/sys

and start compiling with make This will take a while. After compiling you will find the new kernel in this path: /usr/sys/relocunix

  • This file must be copied to /stand: cp /usr/sys/relocunix /stand/relocunix

and then be installed into the boot partition: cd /stand

  • make bootpart KERNEL=relocunix
  • After the installation you need to reboot the system: cd / and shutdown -i6
  • After reboot, Ariadne can be found under /dev/aen0. Without any settings, typing ifconfig aen0

should display something like this:

aen0: flags=23<UP, BROADCAST, NOTRAILERS>

	inet 127.0.0.1 netmask FF000000 broadcast 127.255.255.255
