I'd like to ask recommendation on open source Network Access Control systems. I read packetFence and FreeNac are open source.Are they good? any others to be considered?

Hey Folks, How are ya?

@raz the source IP is Telegram server

@raz I don't understand what u mean, sorry?

@DavidFreitag maybe I don't know what for these packets are. I see their info. as continuation data!!

@DavidFreitag I didn't get it, sorry

I don't have time to do much work...too much pressure and too many works to do in short time

@DavidFreitag Yess, to prove it, Telegram doesn't mention the usage of SSL, yet I found many SSL packets in the communication between the device and their server

core.telegram.org/mtproto/description

I don't have to bother decrypting them

@raz Now I got what I wanted....I got the data packets...I know it's encrypted according to the telegram website explanation

@raz [updates] I changed the wifi I'm using and now I captured the msgs packets for telegram msgs that's the [post,http] ones

HTTP, post

@raz Coz telegram claims to use HTTP,TCP to send the encrypted msgs....But I see many SSL ones!!!

@Ohnana oh thanks man ;)

I was working on telegram but I only captured the ACK, and TCP reassembled PDU packets...But the msg packets are missing

appreciate it

@raz thanks buddy

@raz so the app. perhaps encrypt it first using whatever algorithm then send it in SSL,maybe

@raz okay....Got it now

@RoryAlsop loool

@raz So SSL doesn't implement encryption over the data?

too*

@RoryAlsop MMA..works to?

@RoryAlsop hahaha...maybe

@ sorry whats UTF?

@raz I see

@raz you mean the SSL packets at wireshark capture?

Okay... @RoryAlsop @raz @Ohnana @DavidFreitag and others thanks a lot

@DavidFreitag I saw the wiresharks packets using SSL, doesn't that mean it's encrypted ?

So. it seems no hope to find their encryption algorithm....I mean no reviews or discussions ?..and I don't papers would do that

@Simon okay, sure :)

@Ohnana hahahah...I know I wont be able to do it...at lease not before computers vanish

@raz in that case you only can read the msg if you hack the server....but you can't read it if it's transiting (client--> server, server --> client?

But the thing is that-for now-I'm doing this for crypto class I need to explain about thier encryption..and if it's encrypted I don't have to decrypt it..But I'd love to do that later on..heheh

This is great for me to learn thanks anyway

BTW does my phone needs to be rooted?

@RоryMcCune I see...

@RоryMcCune Thanks alot by the way

@RоryMcCune So in this case all the work would be at the mobile phone..and no need for wireshark?

VPN alike

@raz Do you mean they send it in encrypted channel as plain txts?

But which one?

Because SSL implements various encryption algorithms,isnt?

@raz indeed

algorithm

@Noordung Thanks buddy

But I still need to know the alog.

So far I found from wireshark it uses SSL
