Perform the following steps to enable Radius in PicOS OVS mode:

  1. Enable user map

    admin@PicOS-OVS$sudo /pica/bin/ false
  2. Enable Radius on the PicOS switch.

    admin@PicOS-OVS$sudo /pica/bin/ false
  3. Configure the IP address of the external Radius server on the PicOS switch. In the following example, IP address of the Radius server is and the shared key is abc.

    admin@XorPlus$cat /etc/pam_radius_auth.conf abc 1
  4. Users on the Radius server must be super users. The following example shows the Radius record for user test8

    test8 Cleartext-Password := "pica8"
    Service-Type = Framed-User,
    Framed-Protocol = PPP,
    Framed-IP-Address =,
    Framed-IP-Netmask =,
    Framed-Routing = Broadcast-Listen,
    Framed-Filter-Id = "std.ppp",
    Framed-MTU = 1500,
    Framed-Compression = Van-Jacobsen-TCP-IP,
    Class = "super-user"
  5. Login to the switch via SSH and execute Linux shell commands.

    build@dev-18:$ ssh -l test8
    test8@'s password: 
    test8@PicOS-OVS:~$ version

    test8@PicOS-OVS:~$ pwd
  6. The Radius user must use the full path to execute OVS commands, as shown below:

    test8@PicOS-OVS$sudo /ovs/bin/ovs-ofctl show br0

                Interface "br0"
                    type: internal
  7. User can also modify the path by editing the /etc/sudoers file, so that Radius users can execute OVS commands directly. Change the value of Defaults secure_path from "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/ovs/bin:/ovs/sbin" to another desired value.

    test8@PicOS-OVS:~$ sudo cat /etc/sudoers
    # This file MUST be edited with the 'visudo' command as root.
    # Please consider adding local content in /etc/sudoers.d/ instead of
    # directly modifying this file.
    # See the man page for details on how to write a sudoers file.
    Defaults        env_reset
    Defaults        mail_badpass
    Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/ovs/bin:/ovs/sbin"
    # Host alias specification
