freeradius安装

1 OS：ubuntu18

2安装freeradius

Now to install freeradius, as I use a radius server for user authentication with coovachilli. We will also install some library’s used by coovachilli.

2.1修改共享密钥

Now we need to set it up. open up /etc/freeradius/clients.conf and change the secret from “testing123” to a secure password that you will remember.

/etc/freeradius/3.0/clients.conf

secret = testing123

2.2添加用户

Now for adding users to freeradius. What I do is I delete the file /etc/freeradius/users and just create a new file, and start fresh. Here is the format used for user accounts:

so as you can guess useraccountname is the name of the user, and userpass1 is the password for that account. For the rest of the stuff

• Simultaneous-Use = How many times the same account can be logged in at once.
• Idle-Timeout = How long it will wait to logout the user after idling, in seconds.
• Acct-Interm-Interval = the number of seconds between each interim update in seconds for a specific session.
• WISPr-Bandwidth-Max-Down = The max allowed download speed, in bits (not kilobits)
• WISPr-Bandwidth-Max-Up = The max allowed upload speed, in bits

So with this, create as many users as you want to use. If you don’t want to limit a users speed, or timeout, then just don’t add those lines to that user and it won’t apply.

2.3测试

Next up is testing. restart the freeradius service, and then test the account you made to make sure it authenticates. So, for our above example, we would do the following:

Where SecretCode 共享密钥 is the secret we changed in freeradius earlier in this tutorial. If everything worked, you should get some output like this:

This means the user was authenticated successfully, and freeradius is now setup!
