Per User Bandwidth through Radius.
-
i am using pf not ipfw.
-
I have custom chillispot/coova daemon running pfsense. It replaces the CP that comes with pfsense. It has bandwidth, allowed domains, and many other controls. it uses a local Freeradius & mySQL server within pfsense. Not recommended for embedded users due to the mySQL R/W. I would be happy to share.
Do you have a link I can grab this code from and look at it? Is it documented at all?
-
as far as the chilli deamon, I havn't created a true pfsense package (I don't know how). Although, I have created a gui integrated into the pfsense web gui for configuring the chilli daemon. as far as FreeRadius, as you know, is apart of the pfsense package list. There are some modifications to the FR setup files to get it to work with mysql instead of flat file structure. There are some how tos on getting mysql installed in pfsense, google "mysql pfsense" again, some custom config for getting it to work with mysql.
all in all, its alittle work. maybe the pfsense dev would like to look into working with me in getting this all added as a CP package.

…they are listening already. ;D
SUllrich is THE coding mastermind of pfSense "with a little help of his friends". -
I don't care if it's a package, I'd still like to see whatever code you have (webgui, etc.). Just tar it up. I'm competent enough to manually get it working. I'm really just interested in your implementation of it. If it's not documented, thats fine. I can reverse engineer whatever you have. No hurry, though, I still need to get my dev environment back up and running.

I still want to know how per user bandwidth is working. Call me skeptical but I doubt it's working like you say. Please tell us how it works.
Not trying to sound negative but dummynet which a lot of the captive portal packages use to constrain the bandwidth values does not work with PF currently.

Its been running on my pf platform for months.
Chilli uses RADIUS to provision access and to provide accounting.
Direction of Input and Output
The original ChilliSpot defined input and output as being data uploaded and downloaded by the client respectively. Uses the reverse meaning (per default) making it more compatible with some other commercial access controllers.In RFC 2866, it says:
Acct-Input-Octets
This attribute indicates how many octets have been received from the port over the course of this service being provided.
Acct-Output-Octets
This attribute indicates how many octets have been sent to the port in the course of delivering this service.However, this is not very conclusive as it depends on what side of the port you are referring to. In the manual for a popular commercial access controller, is says:
Acct-Input-Octets
Number of octets/bytes received by the customer.
Acct-Output-Octets
Number of octets/bytes sent by the customer.This is the definition adopted by CoovaChilli - one of the very first changes made to ChilliSpot, for use with back-end systems also supporting commercial access controllers.
Access Provisioning
The following RADIUS attributes are used to place limits on a session authorized by a RADIUS Access-Accept response:Session-Timeout = seconds
Standard RADIUS attribute (defined in RFC 2865) for setting the maximum session timeout. The user is logged out after this amount of time; session duration.Idle-Timeout = seconds
Standard RADIUS attribute (defined in RFC 2865) for setting the maximum idle timeout. The user is logged out after this amount of time of inactivity (no traffic).ChilliSpot-Max-Input-Octets = bytes
ChilliSpot-Max-Output-Octets = bytes
ChilliSpot-Max-Total-Octets = bytes
Chilli vendor specific attributes for setting the max in, out, or total bytes transferred for the session. See above for the meaning of input and output.WISPr-Bandwidth-Max-Up = bits/second
WISPr-Bandwidth-Max-Down = bits/second
WISPr vendor specific attributes for setting the maximum bandwidth rate in bits per second.ChilliSpot-Bandwidth-Max-Up = kbits/second
ChilliSpot-Bandwidth-Max-Down = kbits/second
Chilli vendor specific attributes for setting the maximum bandwidth rate in kbits per second. Internally, chilli multiplies this value by 1000 in converting to bits per second.
In all cases, the ChilliSpot vendor specific attributes override WISPr attribute values. However, using the WISPr attributes is perhaps the more standard way to go.Session Accounting
In RADIUS Accounting, the following attributes are used to report session statistics:Acct-Session-Time = seconds
Duration of session in seconds.Acct-Input-Octets = bytes
Acct-Output-Octets = bytes
The lower 32-bit value of the number of bytes of input and output (see above for a discussion of the meaning of input vs. output).Acct-Input-Gigawords = gigawords
Acct-Output-Gigawords = gigawords
The upper 32-bit value of the number of bytes of input and output; or how many times the above attributes have rolled-over the 32-bit value.Acct-Input-Packets = num-packets
Acct-Output-Packets = num-packets
The number of packets carrying input or output octets. -
nevermind, we are obviously speaking on two different wavelengths. I want to know TECHNICALLY how it is pulling off constraining the bandwidth from a FreeBSD perspective (ipfw divert, dummynet, etc).

np, obviously I don't know what your asking, nor is it important. All I know is I have over 200 users, all with different bandwidth restrictions, all of it running through the chillispot/coovachilli daemon running in pfsense. I guess if you want to know more technical info, you might google chillispot and research for the info you are looking for.
Scott, is this a project you would like to see included in pf? After reading the CP Forums, I see there are lots of CP users who are looking for a more robust CP package besides the one included in monowall/pfsense. What dev is the pfsense team doing currently to improve the CP in pf? Is pfsense still following the monowall dev of the CP?
-
A quick google search shows that it is using ipfw. Please type ipfw show from a command shell and post the output if you do not mind.

chillispot can also be made to use pf, although to what extent I don't know at this point. There were patches for this under freebsd earlier this year that (I think) were committed. Everything I've seen so far shows only NAT and L3 rules. IT would likely be able to be made to talk to tables using pftabled or perl or something, but I don't see any indication of if that is currently the case.
I think what sullrich wants to know is what mechanism you are using to actually perform the QoS (ipfw, pf, some kind of weird alchemy or magic, etc.).
We understand where you are getting the data from to create the rules (radius). If you post your stuff I'm sure it can be reverse engineered to see what it does. -

i am using pf not ipfw.
In that case is it using altq to enforce the bandwidth speed limits? We are looking to reverse engineer how this works.
-
don't understand the "reverse engineer". in any event, anyone who wants futher assistance getting it install on their box we should take it offline as to not ramble on in this thread. send me a pm, and ill help as much as I can.
-
Uhh, what else is this forum for? I would rather keep this public. If you do not wish to help us out that is fine but its not going to be taken private.
-
I am very interested in this but would prefer it if it was a proper pfsense package that way any changes in updates to the pfsense software will not result in this feature failing.
I did a little google search on chillispot this is what i came back with www.chillispot.info i think it is the package the mdouglas has used to make this work.
Thanks everyone

We want to add these types of features to our captive portal in the future. If someone could setup this package on a local system and get the per user bandwidth features working and show the altq/pf/ipfw configuration it would be a HUGE help for us. I would take the time to do it but I have 100 tasks currently in play on top of our pending 1.2 release.

Reverse Engineer in this case just means to look at your work and see what you've done to gain any info we either didn't think to ask or you weren't able to provide. I'm willing to look at this and I actually have a little time at the moment (dunno how long it will last till the next thing comes up, though) so if you'd be so kind, I'd really like to at least see your php gui code. Having everything you've done would be optimal. Feel free to PM it to me or email me directly if you must but I'd much rather keep it in the forum since I tend to get pulled away from stuff and don't want it to get dropped.

Just wanted to say I would love to see this project going somewhere good.
