Menghubungkan Freeradius2 dengan Radius Mikrotik

Ini merupakan posting lanjutan dari konfigurasi mikrotik sebagai radius client.

Pada server freeradius buka file /etc/freeradius/client.conf dengan perintah

sudo gedit /etc/freeradius/client.conf

Lalu tambahkan client mikrotik seperti dibawah ini:

# -*- text -*- ## ## clients.conf -- client configuration directives ## ## $Id$ ####################################################################### # # Define RADIUS clients (usually a NAS, Access Point, etc.). # # Defines a RADIUS client. # # '127.0.0.1' is another name for 'localhost'. It is enabled by default, # to allow testing of the server after an initial installation. If you # are not going to be permitting RADIUS queries from localhost, we suggest # that you delete, or comment out, this entry. # # # # Each client has a "short name" that is used to distinguish it from # other clients. # # In version 1.x, the string after the word "client" was the IP # address of the client. In 2.0, the IP address is configured via # the "ipaddr" or "ipv6addr" fields. For compatibility, the 1.x # format is still accepted. # client localhost { # Allowed values are: # dotted quad (1.2.3.4) # hostname (radius.example.com) ipaddr = 127.0.0.1 secret = radiusbatan # OR, you can use an IPv6 address, but not both # at the same time. # ipv6addr = :: # any. ::1 == localhost # # A note on DNS: We STRONGLY recommend using IP addresses # rather than host names. Using host names means that the # server will do DNS lookups when it starts, making it # dependent on DNS. i.e. If anything goes wrong with DNS, # the server won't start! # # The server also looks up the IP address from DNS once, and # only once, when it starts. If the DNS record is later # updated, the server WILL NOT see that update. # # One client definition can be applied to an entire network. # e.g. 127/8 should be defined with "ipaddr = 127.0.0.0" and # "netmask = 8" # # If not specified, the default netmask is 32 (i.e. /32) # # We do NOT recommend using anything other than 32. There # are usually other, better ways to acheive the same goal. # Using netmasks of other than 32 can cause security issues. # # You can specify overlapping networks (127/8 and 127.0/16) # In that case, the smallest possible network will be used # as the "best match" for the client. # # Clients can also be defined dynamically at run time, based # on any criteria. e.g. SQL lookups, keying off of NAS-Identifier, # etc. # See raddb/sites-available/dynamic-clients for details. # # netmask = 32 # # The shared secret use to "encrypt" and "sign" packets between # the NAS and FreeRADIUS. You MUST change this secret from the # default, otherwise it's not a secret any more! # # The secret can be any string, up to 8k characters in length. # # Control codes can be entered vi octal encoding, # e.g. "\101\102" == "AB" # Quotation marks can be entered by escaping them, # e.g. "foo\"bar" # # A note on security: The security of the RADIUS protocol # depends COMPLETELY on this secret! We recommend using a # shared secret that is composed of: # # upper case letters # lower case letters # numbers # # And is at LEAST 8 characters long, preferably 16 characters in # length. The secret MUST be random, and should not be words, # phrase, or anything else that is recognizable. # # The default secret below is only for testing, and should # not be used in any real environment. # secret = testing123 # # Old-style clients do not send a Message-Authenticator # in an Access-Request. RFC 5080 suggests that all clients # SHOULD include it in an Access-Request. The configuration # item below allows the server to require it. If a client # is required to include a Message-Authenticator and it does # not, then the packet will be silently discarded. # # allowed values: yes, no require_message_authenticator = no # # The short name is used as an alias for the fully qualified # domain name, or the IP address. # # It is accepted for compatibility with 1.x, but it is no # longer necessary in 2.0 # # shortname = localhost # # the following three fields are optional, but may be used by # checkrad.pl for simultaneous use checks # # # The nastype tells 'checkrad.pl' which NAS-specific method to # use to query the NAS for simultaneous use. # # Permitted NAS types are: # # cisco # computone # livingston # max40xx # multitech # netserver # pathras # patton # portslave # tc # usrhiper # other # for all other types # nastype = other # localhost isn't usually a NAS... # # The following two configurations are for future use. # The 'naspasswd' file is currently used to store the NAS # login name and password, which is used by checkrad.pl # when querying the NAS for simultaneous use. # # login = !root # password = someadminpas # # As of 2.0, clients can also be tied to a virtual server. # This is done by setting the "virtual_server" configuration # item, as in the example below. # # virtual_server = home1 # # A pointer to the "home_server_pool" OR a "home_server" # section that contains the CoA configuration for this # client. For an example of a coa home server or pool, # see raddb/sites-available/originate-coa # coa_server = coa } # IPv6 Client #client ::1 { # secret = testing123 # shortname = localhost #} # # All IPv6 Site-local clients #client fe80::/16 { # secret = testing123 # shortname = localhost #} #client some.host.org { # secret = testing123 # shortname = localhost #} # # You can now specify one secret for a network of clients. # When a client request comes in, the BEST match is chosen. # i.e. The entry from the smallest possible network. # #client 192.168.0.0/24 { # secret = testing123-1 # shortname = private-network-1 #} # #client 192.168.0.0/16 { # secret = testing123-2 # shortname = private-network-2 #} #client 10.10.10.10 { # # secret and password are mapped through the "secrets" file. # secret = testing123 # shortname = liv1 # # the following three fields are optional, but may be used by # # checkrad.pl for simultaneous usage checks # nastype = livingston # login = !root # password = someadminpas #} ####################################################################### # # Per-socket client lists. The configuration entries are exactly # the same as above, but they are nested inside of a section. # # You can have as many per-socket client lists as you have "listen" # sections, or you can re-use a list among multiple "listen" sections. # # Un-comment this section, and edit a "listen" section to add: # "clients = per_socket_clients". That IP address/port combination # will then accept ONLY the clients listed in this section. # #clients per_socket_clients { # client 192.168.3.4 { # secret = testing123 # } #} #client mikrotik client 192.168.16.28 { secret = radiusbatan }

Perhatikan pada baris paling akhir, ini merupakan deklarasi RADIUS client.

#client mikrotik
client 192.168.16.28 {
secret = radiusbatan
}

Jika anda ingin menambah client lainnya, silahkan deklarasi IP client dan radius secret seperti syntax diatas.

Lalu simpan, dan hentikan service Freeradius dengan perintah:

sudo su

/etc/init.d/freeradius stop

Lalu test koneksi dengan menjalankan freeradius debug mode. Dengan perintah:

sudo su

freeradius -X

Buka terminal lagi lau test koneksi dengan perintah:

radtest "username" "password" 127.0.0.1 1812 passwordradius

Jika tampilan seperti diatas maka koneksi sudah berjalan.
