radius

a Go (golang) RADIUS client and server implementation

The datatypes currently supported are:

type description
string ASCII string
ipaddr IPv4 address
date 32 bits UNIX
octets arbitrary binary data
ipv6addr 16 octets in network byte order
integer 32 bits unsigned number
signed 32 bits signed number
short 16 bits unsigned number
byte 8 bits unsigned number

Example

Parse packet

p, err := radius.Parse(request, secret)
if err != nil {
	t.Fatal(err)
}
// Get a attribute by name
if p.GetByName("User-Name").(string) != "nemo" {
	t.Fatal("expecting User-Name = nemo")
}
// Get a attribute by type
if p.Get(radius.AttrUserName).(string) != "nemo" {
	t.Fatal("expecting User-Name = nemo")
}

Build attributes with tags

attr := make(Attributes)
attr.Set(AttrTunnelPrivateGroupId.WithTag(1), []byte("test1"))
attr.Set(AttrTunnelPrivateGroupId.WithTag(2), []byte("test2"))
if attr.Get(AttrTunnelPrivateGroupId.WithTag(1)).(string) != "test1" {
	t.Fail()
}
if attr.Get(AttrTunnelPrivateGroupId.WithTag(2)).(string) != "test2" {
	t.Fail()
}
