Hi there, Freeradius version: 2.2.5 I have a question relating to how if statements applied to a packet are handled. I have a packet something like this (I¹ve snipped a load of stuff) that contains 2 class attributes: Framed-Protocol = PPP Class = 0x5030323a3*************************************** ... Class = 0x434653494421**************** ... I am trying to overwrite some attributes in the post-auth section based on a Class attribute matching a given string being present. I can get this working like so using a sting comparison on the hex: if( reply:Class =~ /^0x5030323a3/ ) { update reply { ... } } What I can¹t get to work is making the if statement check the second Class attribute (the one I actually want to check!). It is not feasible to change the order they appear because of the complexity of the system (and tbh I would probably not want to assume it would always be second). So if I go with: if( reply:Class =~ /^0x434653494421/ ) { update reply { ... } } The debug shows it trying and failing to match ++? if (reply:Class =~ /0x434653494421/ ) ? Evaluating (reply:Class =~ /0x434653494421/) -> FALSE ++? if (reply:Class =~ /0x434653494421/ ) -> FALSE Any ideas? I can¹t find anything in the docs or on google (mainly because its a really hard search term) Thanks, -- Josh Berry Senior Systems Engineer Plusnet PLC | www.plus.net Phone: 01142 733547 Registered Office: The Balance | 2 Pinfold Street | Sheffield | S1 2GU Registered in England no: 3279013
