Client definition
FreeRADIUS defines the connected RADIUS clients in the file /etc/raddb/clients.conf. This file needs to hold all your connected Access Points and/or wired eduroam-enabled switches. You set a shared secret for each client and define these in the config file as follows:
| Code Block |
|---|
client antarctica-access-point-1 {
ipaddr = 172.25.1.55
netmask = 32
secret = yoursecret12345
shortname = southpole-11g
virtual_server = eduroam
}
|
There are more (optional) settings for clients; please consult the comments in clients.conf for more detail. One option, the "virtual_server" one, enables your RADIUS server to serve more purposes than only eduroam: you can define several other virtual servers for other RADIUS purposes, and link clients to these. That is beyond the scope of this documentation, though.
If you want to connect your clients over IPv6, the syntax is only slightly different:
| Code Block |
|---|
client antarctica-access-point-2 { ipv6addr = 2001:db8:1:789::56
netmask = 128
secret = yoursecretABCDE
shortname = southpole-11n
virtual_server = eduroam
}
|
Request forwarding
FreeRADIUS contains a wealth of options to define how requests are forwarded. These options are defined in the file /etc/proxy.conf. For a single eduroam SP, these may seem overkill, but the required definitions for that purpose are rather static. Assuming you have two upstream servers to forward requests to, the following configuration will set these up - you only need to change the IP addresses and shared secrets in home_server stanzas.
| Code Block |
|---|
proxy server {
default_fallback = yes
}
home_server antarctica-flr-1 {
type = auth+acct
ipaddr = 172.20.1.2
port = 1812
secret = secretstuff
status_check = status-server
}
home_server antarctica-flr-2 {
type = auth+acct
ipv6addr = 172.25.9.3
port = 1812
secret = secretstuff
status_check = status-server
}
home_server_pool EDUROAM {
type = fail-over
home_server = antarctica-flr-1
home_server = antarctica-flr-2}
realm DEFAULT {
pool = EDUROAM
nostrip
}
