To get by the work of those kittens I set up a remote login to run radmin commands and parse the output so it is suitable for mrtg. It has worked well for me.

Hi all, Really appreciate all your kind supports and helps very much. Alan..I didn't meant to be inaccurate about describing my situation...I just don't want to blur my question with too many details. Well, I think I didn't keep the balance well. If let you feel bad, I'm very sorry about that. Then you mentioned keeping information in the gateway...in fact, it's a long story.. Anyway, I agree the most part of your point. However, in some kind of situation, I almost can't avoid that. Like this time, due to lacking of supporting on another mandatory attribute(Chargeable-User-Identity) that external AAA needs in our wi-fi gateway, we decide to make this workaround without database. The less database transaction, the better solution it would be. This is the principle we follow on the implementation of RADIUS Proxy server. Our proxy server is like a guard who should check and make many policy or criteria before requests are proxied out. So we do our most effort to prevent us from relying on database. And Thank to Olivier! I've been desired to try 3.0.0 for a long time, while there isn't a good chance for. I've found some new and helpful features in 3.0.0 about Unlang, but never experience them yet. The functions you mention are really helpful. Maybe I should start to plan migrating to 3.0.0. And also thanks for SerpentoR, but unfortunately I can't know which index of Class array is what I want, and even cannot sure about how many items in Class array. So such like "foreach" could be my need for solving this problem. Thanks for all respondents again! Sincerely, Okis.

Use Tmp-String-0, or Tmp-Octets-0 instead. That way the problem goes away. See "dictionary.freeradius.internal" for more examples. > Then erase it before sending request or reply out.

Alan DeKok. ------------- Hi Alan, Thanks for reply. Yes, I totally can understand the solution you recommend, and I've been using this skill for quite a long time. But the situation I encountered is : 1. I need to save some information returned in Access-Accept from external AAA in the attribute *Class* at the section *post-auth*. So it will return back to gateway. 2. Then gateway will send Accounting-Start to my server. In this time, I need to pop out the information I saved in the attribute *Class* in the section *accounting* so that I can generate the avp what I need. Hence, it cannot work by using Tmp-XXX internal attribute because those two events occur in two different sessions to FreeRADIUS. I thought Tmp-* attributes will not exist across two sessions at the same time. So that way I must choose some kind of attribute that gateway must return back for saving temporary attribute value. Concerning about total available length of Class in our wifi gateway, I don't want to do such a waste on attribute Class. Again, just like I said before, because Class is a multi-value attribute I can't find a way to remove a specific value from entire Class array. But anyway, if this is too much for unlang I can use perl to fulfill this definitely. Just curious about if unlang can totally achieve this. :P Cheers, Okis.

Is there anyone can help? Actually I can write a short perl script to do this, but I try to do with pure unlang. So.if someone can told me whether this purpose can be done with only unlang, I can save lots of time on this endless trial. Lol In fact, the reason why I need this function is that sometimes we treat some attributes as temporary variable for generating another attribute value pair. Then erase it before sending request or reply out. So I am wondering would majority of FR user do this things like this? I personally pretty love this way for some policy processing, and that how FreeRADIUS to be powerful and flexible I think. So I believe there might be somebody else probably need this. Alright.just free chat. Cheers, Okis.
