Programming freeradius to react in different way for accepts and rejects
Hello all, I'm looking for some tutorial that explain how I can programming the freeradius to work as described below. At my lab environment I have two situations: access-accept (the password is correct) and access-reject (the password is wrong). I would like to programming the freeradius to after the fifth try of an user to authenticate (all five tries was reject), the freeradius authenticate the user within a specific policy for this case. I know how to send different policies to user, but I don't know how to make freeradius answer accept after the fifth try of authentication. Example: user test passwd test123 time: 00:00:00 1st try: test passwd test456 -> radius answer reject 2nd try: test passwd test456 -> radius answer reject 3rd try: test passwd test456 -> radius answer reject 4th try: test passwd test456 -> radius answer reject 5th try: test passwd test456 -> radius answer reject time: 00:05:00 6th try: test passwd test456 -> radius answer accept but athenticate the user in a specific policy to block its access but keep it authenticated. If in five minutes the user has received more than 5 access-reject then I would like to authenticate and block its access with a specific policy. Thanks in advance! ./diogo -montagner
Create a (perl, exec) program that handles authentication that way. Ivan Kalik Kalik Informatika ISP Dana 8/10/2008, "Diogo Montagner" <diogo.montagner@gmail.com> piše:
Hello all,
I'm looking for some tutorial that explain how I can programming the freeradius to work as described below.
At my lab environment I have two situations: access-accept (the password is correct) and access-reject (the password is wrong).
I would like to programming the freeradius to after the fifth try of an user to authenticate (all five tries was reject), the freeradius authenticate the user within a specific policy for this case. I know how to send different policies to user, but I don't know how to make freeradius answer accept after the fifth try of authentication.
Example:
user test passwd test123
time: 00:00:00 1st try: test passwd test456 -> radius answer reject 2nd try: test passwd test456 -> radius answer reject 3rd try: test passwd test456 -> radius answer reject 4th try: test passwd test456 -> radius answer reject 5th try: test passwd test456 -> radius answer reject time: 00:05:00 6th try: test passwd test456 -> radius answer accept but athenticate the user in a specific policy to block its access but keep it authenticated.
If in five minutes the user has received more than 5 access-reject then I would like to authenticate and block its access with a specific policy.
Thanks in advance!

Write a Perl script to implement this logic. It is a *very* unusual request, and cannot be implemented in the normal configuration files. You will need to keep track of the number of rejects in a DB. Alan DeKok.
And how I can say to freeradius always ask this script before it authenticate an user ? Thanks ./diogo -montagner On Wed, Oct 8, 2008 at 12:06 PM, Alan DeKok <aland@deployingradius.com>wrote:

See the example configuration files for how to configure the "perl" module. Alan DeKok.
