linux - Cannot connect with WPA2 (AES) encryption + EAP-TTLS PAP with FreeRADIUS auth


I successfully set up an enterprise Wi-Fi connection with LDAP authentication by way of FreeRADIUS. I used EAP-TTLS PAP because I have hashed passwords in my OpenLDAP directory.


When I use TKIP wireless encryption for that WPA2 access point, everything goes very well and my Android phone clients connect just normally (until now all clients have just been Android phones).


BUT when I use AES, the clients cannot connect any more, and I don't know why. The log seems very good, and I tried and searched a lot with unfortunately no success.


Here is my FreeRADIUS log: http://pastebin.com/gF1tBGkM


You may ask why I want AES. That is because Microsoft Windows does NOT allow the TKIP algorithm for enterprise WPA2 connections (maybe just to annoy us and make the matter harder).


I tried all the open source free third party software to be able to use the unsupported protocols, but they where all very old and they didn't work, and I am trying to do everything natively without any third party software.


Could anybody help me please to find any solution for that (to get my client connects successfully with AES)?



Answer



OK, I was not considering that the problem might be from my DD-WRT itselt, and it was!!


I googled for "TP-LINK AES DD-WRT problem". The posts in this page helped me to solve the problem: http://www.dd-wrt.com/phpBB2/viewtopic.php?p=762001 one guy said, that when he upgraded his firmware, his problem (as my problem, he couldn't connect when using AES) was solved.

much appreciated.

I have the same problem few days ago when I started to use DD WRT.


I fixed by downloading latest version (05-27-2014-r24160) from here http://dd-wrt.com/site/support/other-downloads?path=others%2Feko%2FBrainSlayer-V24-preSP2%2F



So I upgraded my router firmware, and it worked again like a charm! and my android clients were able to connect just perfectly!


Unfortuanately windows clients not, apparently I am missing something while setting the connection in windows up.

keyboard - Is there any utility/method to change Windows key bindings to type rare chars to currently empty bindings?

I'm currently typing this post with my windows XP machine and (Spanish) keyboard, and I'd like to add some extra symbols to my text. I could open the "char map" windows utility, look for the desired symbols, and paste them. But I'd like something quickier. For example, when I'm using my OSX Mac at work, I can easily add a ©, ™, ® or similar symbols, just pressing some weird ALT-GR + G / H / J, key combinations. In my (Spanish) keyboard mapping, these combinations are empty, as they don't produce any char at all, which, on the other hand, is perfectly normal and desirable. So, I thought: Why couldn't I add some extra key mappings on top of my currently empty ALT-GR + G/J/H Keys in my Spanish keyboard, and thus, being able to quickly type these special symbols? So that's my question: Is there any utility/method to achieve that effect under windows? (My version is XP). I've even googled this for some time but no luck. I've been a long term Hot...

virtualization - How to select paravirtualization interface in VirtualBox?

Given a windows 8 host system (Intel Core i5) and a Linux Fedora host, I would like to determine the optimal setting for the paravirtual interface. Options are none Default Legacy minimal Hyper-V KVM This page suggest the selection is only based on the guest system: The biggest change in VirtualBox 5.0 is the introduction of paravirtualization support, bringing higher performance and time-keeping accuracy to supported guest operating systems (Hyper-V on Windows and KVM on Linux). Is that correct? Answer The VirtualBox Manual , in the section titled Paravirtualization providers explains very clearly when each should be used (emphasis added): Minimal: Announces the presence of a virtualized environment. Additionally, reports the TSC and APIC frequency to the guest operating system. This provider is mandatory for running any Mac OS X guests. KVM: Presents a Linux KVM hypervisor interface which is recognized by Linux kernels starting with version 2.6.25. VirtualBox's implementati...

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...
