FreeRadius: PPTP - RADIUS and client IP address
-
i was planning on trying to add some things to the freeradius gui and the radiusd.conf this weekend
stuf like :
expire
session-timedon't now if the freeradius package is already on version 1.1.13 ?
then also:
logintime added to user file and radiusd.conf (alaws to only be online between the times and days that are given for that user)
user defined counters added to radiusd.conf
user defined counter atributs to user file
so that you can limet on the max sesions you can make
limet the max online time a day,week,month etcmaybe a extra textbox for extra things to add to a user like the static ip stuff ?
-
Now, I finished the freeradius package gui for assigning ip address to user and multiple connection control. I spent almost the day for it.
Dear Hoba,
If you don't mind, I will send the files of vpn.inc, vpn_pptp.php, freeradius.inc and freeradius.xml to you via e-mail.Dear Jeroen234,
It's good news. I'm waiting for your version that will support more functions. If you don't mind I'd like to send the files to you as well. I think it may help for your work. -
Can you just attach them as diffs against the latest version of the files that you changed here? This way maybe jeroen can merge them together with his changes too.

Dear Jeroen234,
It's good news. I'm waiting for your version that will support more functions. If you don't mind I'd like to send the files to you as well. I think it may help for your work.no problem send them to jeroenjohanzwarts at hotmail dot com
i will them add the extra functions to those files
don't now if you have made the Simultaneous-User function a user based one
or just a globel one
if it is globel then i will add a user based one -
I will send the files to your e-mail. And I'v made user based Simultaneous-Use fuction.
-
got them thanks
[edit]
this is what i have working now:
Expiration , Session-Timeout , Onlinetimeuser file:
john User-Password == "doe", Simultaneous-Use += 1, Expiration := "101020081010"Framed-IP-Address = 10.10.10.10,
Login-Time := "Any0800-2000",jeroen234 User-Password == "jeroen234", Simultaneous-Use += 1, Expiration := "121220071010"
joop User-Password == "joop", Simultaneous-Use += 1, Expiration := "201020081010"
sint User-Password == "sint", Simultaneous-Use += 1
Session-Timeout := 500,

Dear Jeroen,
It looks so good. Pfsense will have the strong radius server functions.
Dear Hoba,
As I mentioned before, we need some modifictions on pfsense's pptp so that it uses the reply from radius server for assigning the ip address from radius server to pptp users. The files involved in it are vpn.inc and vpn_pptp.php. I'm posting my new files here for your information.

Nice, but we need the files as diffs against the latest revisions of the files you changed to merge them into the pfSense code. Can you attach diffs?
-
here are my diff's for freeradius.xml and freeradius.inc
on the weekend i will add counter atrr. to freeradius.xml and freeradius.inc
the counters are already eneabled in radiusd.conf -
I have a problem. I don't know how to make the diffs file.
Pls adv me how to make the diffs file so that I can make diffs for vpn_pptp.php and vpn.inc.

Here are the diffs for vpn.inc and vpn_pptp.php.
I used vpn.inc version 1.12 and vpn_pptp.php version 1.38. -
Dear Jeroen,
Could you add the description column for freeradius users? I think it is needed for users contact number, email address or his real name.
Thank you.
-
oke than i will add it in frond of the username
there are comming 4 more colom's in the weekend
and suport for 3 more in the future ( upload en download speed settings and wisp redirect url) -
Hi All,
I haven;t checked the forums for a while since I posted this initial thread.
However, I am pleasantly surpised that some work has been done on the freeradius package :)
Just wanted to ask whether the new freeradius package is now available. I checked the package version and the latest one was 1.1.2 - so I installed this. However, I did not get any changes to the interface to allow config of the IP address in the account configuration.
Is the 1.1.2 version meant to include this feature - or is this feature still needs to be patched in and released?
Thanks for all your hard work.
Regards,
Mon
-
Have the radius extensions made it into CVS yet?
-
the last time i looked they were not yett in
-
Any updates on when these new features will be available?
