Aros/User/Networking
AROSTCP is the TCP/IP stack of choice for AROS based computers.
It is a port of the AmigaOS AmiTCP TCP/IP subsystem to AROS by Neil Cafferkey.
Since its initial port it has undergone a number of changes based on work by AROS developers, as well as backported changes from the MorphOS port (Pavel Fedin - SonicAmiga) it spawned.
AROSTCP Files
[edit | edit source]AROS has a Network prefs located in the Prefs directory. Please use it to set up internet/ethernet use.
AROSTCP is located in 'Extras/Networking/Stacks/'. It consists of the following directories and files:
C/ contains networking executables, mostly as known from UNIX/Linux.
AROSTCP The AROSTCP executable. Don't run directly, use startnet/stopnet instead (see below). arp dhclient hostname ifconfig logger ping resolve route
S/ contains start and stop scripts
Package-Startup startnet stopnet
db/ contains configuration files, see AROSTCP Configuration Database.
general.config group hosts inet.access inetd.conf interfaces netdb netdb-myhost netdb-myhost.example networks passwd protocols services static-routes
AROSTCP Environment Variables
[edit | edit source]AROSTCP uses a few Env: settings to control its most basic operation.
Currently the following options exist..
SYS/Packages/AROSTCP This is an AROS package file which tells the AROS package subsystem where AROSTCP is installed. If it is incorrect AROSTCP will fail to load. During system boot this variable is used to set up paths and assigns needed by an application.
AROSTCP/Config Points to the location of AROSTCP's configuration files. These will be used to configure the stack to a users preference. By default the configuration is in <AROSTCP DIR>/db but it is preferred to copy these files and customise them to suit - see "AROSTCP Configuration Database"
AROSTCP/AutoRun when set to true this causes the AROSTCP stack to load during boot. by default it isn't enabled so that users may manually configure the stack and confirm it is working before enabling boot time operation. If you don't use the AutoRun feature you should start AROSTCP by going to its directory and typing "execute s/startnet"
File:AROSTCP-Warning.jpg Presently the SetEnv command wont make the AROSTCP drawers to store the settings in - so you may need to manually create them before hand using
>makedir ENV:AROSTCP >makedir ENVARC:AROSTCP
AROSTCP Configuration Database
[edit | edit source]Configuration Database Location(s)
[edit | edit source]The Configuration files are installed to "<AROSTCP DIR>/db" by default - and unless the "AROSTCP/Config" Env variable is set, AROSTCP will attempt to load them from there.
It is preferable however to leave these files, and customize a copy which will not get overwritten when updating AROS/AROSTCP. From hereon in we will refer to this location as <db Dir>.
To do this enter the following at a shell prompt..
>cd <AROSTCP DIR> >makedir <db Dir> >copy db <db Dir> ALL >SetEnv SAVE AROSTCP/Config <db Dir>
.. substituting <AROSTCP DIR> with the location AROSTCP is installed to (for instance "SYS:Extras/Networking/AROSTCP" by default), and <db Dir> with a location of your choice for your personalised config files (i.e. "SYS:Storage/NetConfig").
Customising the Configuration Database
[edit | edit source]Most modern home networks provide DHCP addressing/configuration to ease setup of internet access for users. If you use this on your network - or arent sure then this is the configuration option you should most likely use.
For more advanced/experienced users there is manual ip configuration for a brief summary of configuration options required to get AROSTCP working with custom IP address etc.
Basic Configuration - DHCP
[edit | edit source]AROS has a Network prefs located in the Prefs directory. Please use it to set up internet/ethernet use.
Basic Configuration - Manual IP
[edit | edit source]AROS has a Network prefs located in the Prefs directory. Please use it to set up internet/ethernet use.
At a bare minimum the following files will need to be edited to enable operation on your network.
<db Dir>/interfaces <db Dir>/static-routes <db Dir>/netdb-myhost
These will provide the necessary information to allow AROSTCP to correctly configure your hardware and network environment.
<db Dir>/interfaces
[edit | edit source]This file contains lines to configure the network hardware on your system. each line consists of the following:
<interface name> DEV=<hardware driver> UNIT=<hardware driver unit no.> <further configuration data>
i.e.
eth0 DEV=pcnet32.device UNIT=0 IP=192.168.0.10 UP
Would provide an interface named "eth0" which uses unit 0 of pcnet32.device (PCNet32 compatible controllers), configures it for the IP address 192.168.0.10, and sets the device to go active (UP) immediately.
<db Dir>/static-routes
[edit | edit source]At the moment this file only provides the IP address of your gateway device (DEFAULT GATEWAY) - so make sure and change it to suit your network.
You can add any routes your network needs to this file.
<db Dir>/netdb-myhost
[edit | edit source]netdb-myhost provides name resolution details for your network environment. If your IP address' DNS name cannot be resolved from the nameservers, then you will need to specify it in here.
presently the following data is needed:
HOST 192.168.0.10 thisarosbox.mynetwork thisarosbox
specifies the hostname for the interface we configured in <db Dir>/interfaces which has the IP address 192.168.0.10
DOMAIN mynetwork 192.168.0.
This is the network our machine belongs to.
NAMESERVER 192.168.0.2
The NAMESERVER option lets us specify DNS servers which AROSTCP will use to resolve names (such as www.aros.org)
depending on your configuration this will be set to one of the following -:
- Your private network's DNS servers IP
- Your routers IP address if it can forward DNS requests
- DNS server address's provided by your ISP.
N.B: It is perfectly legal to list more than one NAMESERVER line for multiple DNS servers.
Basic Configuration - Linux hosted: tap.device
[edit | edit source]To be able to use networking under AROS Linux hosted, a "tap.device" has been created, which attaches a Linux tunneling device on the hosting machine to AROSTCP inside the hosted AROS system.
Linux Tap/Tun Configuration
[edit | edit source]You need 'tunctl' to create a tunneling network device under Linux. You might need to install it - it can be found e.g. as part of the uml-utilities package.
A command line to create the device might look like this:
tunctl -b -u arosuser -t aros0
This allows a user called 'arosuser' access to a newly created network device called 'aros0'.
Next, assign an IP address to the device, and bring it up:
ifconfig aros0 192.168.0.20 ifconfig aros0 up
tunctl also creates a linux filesystem entry, e.g. /dev/net/tun (see tunctl help for more), you might need to set access privileges for your user, e.g.:
chmod 666 /dev/net/tun
This allows read and write access for all users.
Now you're ready to run AROS.
Finally, after running AROS and starting AROSTCP, you might need to set a route to the hosted AROS system. Use the IP address from your <db Dir>/interfaces configuration (e.g. 192.168.0.188):
route add -host 192.168.0.188 dev aros0
AROSTCP Configuration for tap.device
[edit | edit source]The general configuration is done as usual (see section Basic Configuration - Manual IP).
Use these values where appropriate:
- <db Dir>/interfaces : "tap.device" should be used as the interface device driver. The unit number is the same as the Linux network device's number that was created with tunctl.
- <db Dir>/static-routes : The DEFAULT GATEWAY Address to be used is the IP address of the tunneling device under Linux.

[edit | edit source]Network Troubleshooting
[edit | edit source]Configuration and Basic connectivity issues
[edit | edit source]Check your environment
[edit | edit source]Before doing anything, its best to check AROSTCP has the correct ENV settings
# Check the package file ENV:SYS/Packages/AROSTCP points to the location AROSTCP is installed to. # Check that ENV:AROSTCP/ exists # Check if ENV:AROSTCP/Config is set and points to your network config. # Check if the ENV:AROSTCP/AutoRun option is set and disable to manually test.
After checking, change to the directory AROSTCP is installed to and type
>execute s/startnet
AROSTCP should now load, and return you to the command prompt.
Check your Interfaces
[edit | edit source]Now you may wish to verify your network card is operational using
>ifconfig -a
which should output something similar to the following
lo0: flags=8<LOOPBACK> mtu 1536 inet 127.0.0.1 netmask 0x0 eth0: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX> mtu 1500 address: 00:0c:29:37:ef:6d inet 192.168.0.10 netmask 0xffffff00 broadcast 192.168.0.255
Look for the "UP" flag which will tell you if your interface is running, and if not check if inet = 0.0.0.0. If this is the case AROSTCP likely couldn't load the driver for your interface so check your interfaces file is configured correctly for your hardware.
If there is a correct inet address but the interface isn't "UP" - try the following command.
>ifconfig <the interface name .. i.e. eth0> <the inet address to use> UP
Then check your interfaces again.
Check your Gateway
[edit | edit source]If your connected to the internet via a router its IP address should be stored in <db Dir>/static-routes.
We can check if its working by trying to ping it
>ping <ip address of gateway/router>
Which should respond and inform us of received packets (ones sent back)
If you do not get packets back then check your cabling is correct.
The next step requires an external IP address (i.e. one from an internet based site) here I will use www.yahoo.com's current IP [69.147.114.210]
>ping 69.147.114.210
Again, you should get packets received from this operation signaling success.
If it returns "no route to host", you may have an incorrect setting in db/static-routes or an incorrectly configured interface - so please check.
Check Name resolution
[edit | edit source]DNS server s are stored in your <db Dir>/netdb-myhost file
To test they are working simply ping an external site by name ..
> ping www.yahoo.com
And you should get returned packets.
