What is RadMan

Simply, RadMan is a FreeRadius Management GUI.
We wrote RadMan because we were not happy with existing FreeRadius management options.

RadMan does not manage FreeRadius itself (it does not touch the FreeRadius config files).
What RadMan offers is an easy way to manage a FreeRadius DB in a web interface.

RadMan aims to be simple to use, super fast to deploy and easy to maintain.

How does RadMan work

RadMan works by inserting / updating / removing records from the FreeRadius database tables.
RadMan also requires a database itself, for storing it's own data.

RadMan therefore initiates 2 DB connections:

Radius DB

For the Radius DB, RadMan manipulates all required tables to manage a Radius database:
nas, radacct, radcheck, radgroupcheck, radgroupreply, radhuntgroup, radreply, radusergroup

Just by deploying RadMan and pointing it at a working FreeRadius database, you will be able to see a list of NASes (nas table), NAS groups (radhuntgroup table), user/group mappings (radusergroup table) and the accounting table (radacct).

To see records from radcheck, radgroupcheck and radreply and radgroupreply, you will have to tell RadMan which Radius Attributes you want it to manage.
If you want RadMan to simply manage everything you already have in your Radius deploy, click Load from Radius for both Authentication attributes and Authorization attributes in the Attributes menu.

After this, you can check the Auth (AA) menu in the Radius section, and you should see full Attribute mappings for your users and groups (as mentioned, these come from radcheck, radgroupcheck, radreply and radgroupreply tables).

To manage Users and Groups, you will want to tell RadMan which Users and Groups it should manage.
As previously, to simply manage everything you already have in your Radius deploy, click Load from Radius in the Users and Groups menus.

You will now be able to fully manage Radius users and groups in RadMan.
This enables full attribute assignments for Autorization (radcheck and radgroupcheck table) and Authorization (radreply and radgroupreply table) under the Auth (AA) menu.
You can now also manage group memberships for users in the User/Group menu.

RadMan DB

By using the various menus from the Radius category, you can manage the Radius DB.
In the RadMan menu category, you are in turn managing the RadMan database.

The RadMan database has 3 purposes:

It tells RadMan which of your Radius Users/Groups/Attributes it should manage.
(see Radius DB section for more details)

It acts as a repository for all Users/Groups/Attributes you can use/configure in RadMan.
Even if these Users/Groups/Attributes are not present in the Radius DB directly, you can still add them into the Radius DB from RadMan (if we didn't store them in a DB somewhere, they would completely disappear from RadMan if removed from the Radius DB).

It allows you to delete entities globally from the Radius DB.
For example, when deleting a User in Users menu in RadMan, you have the option Remove from Radius. This would remove this user from all appropriate tables in the Radius DB - radcheck, radreply and radusergroup.
No more having to crawl through tables manually, or forgetting to clean something up!

As another example, when deleting an Attribute in the Attributes menu in RadMan, and checking Remove from Radius, that attribute will automatically be removed from all records in the radcheck, radgroupcheck, radreply and radgroupreply tables. This makes it super-easy and super-fast to remove no-longer used attributes withouth crawling through all the tables yourself.

Please note that User / Group deletions will not delete records from the Accounting (radacct) table.

How to deploy RadMan

Before you deploy RadMan, you will need a Java Runtime Environment.
You can install openjdk-8-jre or openjdk-11-jre - whichever is available for your Linux distribution.
Use apt-get install ... or yum install ... or whatever is appropriate for your environment.

Before you proceed further, please make sure that java -version works, and returns the expected Java version.

Now download a release binary from our GitHub Releases.
After that, run:

mkdir /opt/radman
mkdir /etc/radman

unzip radman*.zip

mv RadMan.jar /opt/radman/RadMan.jar
mv -i radman.properties.example /etc/radman/radman.properties
mv -i radman.default /etc/default/radman
mv -i radman.service /etc/systemd/system/radman.service

systemctl daemon-reload

After this, you will want to adjust the configuration file.
Check the How does RadMan work and RadMan config file sections for more info.
(use your favorite editor like nano instead of vim if you wish)

vim /etc/radman/radman.properties

After the config file is properly setup, start RadMan:

systemctl enable radman
systemctl start radman

You can check the log file to see if everything is running:

tail -f /var/log/radman

You should now see RadMan running at http://your-server-ip:8089.
You may need to adjust iptables or other firewalls to allow connections to 8089 on your server.

When connecting to RadMan for the first time, there will be no users in it's user database.
Check the log file for one-time login credentials so you can perform the first login (tail -f /var/log/radman).
After the first login, generate your RadMan users in the System users menu.

How to upgrade RadMan

Download a new release binary from our GitHub Releases.
You will want to extract RadMan.jar from the release package.

Now, just replace /opt/radman/RadMan.jar with the newer version and restart the service.

systemctl stop radman
mv RadMan-new.jar /opt/radman/RadMan.jar
systemctl start radman

Please make sure to read the Changelog, as some releases might have more specific migration instructions included.

RadMan config file

The RadMan config file (radman.properties) should be fairly straight-forward to understand. We ship and example file in the config-files directory, which you can adjust for actual RadMan deployments.

From the example file, you will want to adjust 4 values enclosed in [...] (square-brackets) for both the radius database and the internal database sections.

The radius database section should point to a fully configured Radius database.
The internal database section should point to a database that RadMan itself will use.
(this should be empty - RadMan will initialize it automatically on it's first run)

RadMan also allows user auth into RadMan itself using LDAP.
You should configure the appropriate settings in the ldap section if you wish to use this.

Common startup issues

Most RadMan startup issues will occur because of FreeRadius database incompatibilities.
RadMan expects the FreeRadius DB schema to conform to the latest official FreeRadius v3 schema.

Here is the schema that RadMan expects to find in the FreeRadius DB:

RadMan also expects to find a radhuntgroup table, as described here:

RadMan can fail to start with errors such as:

SchemaManagementException: Schema-validation: missing column [xxx] in table [xxx]

This simply means you need to fix your FreeRadius DB schema as per the latest official FreeRadius v3 schema linked above.
You should just be able to add the missing columns to existing tables, and RadMan should start working.
