IP-over-ICMP

Hi guys. I was just wondering what software VPN providers use with this kind of tunneling and probably with DNS tunneling too with PAM authentication (I think)... Googled it and haven't found anything but shared password. If you know how to do that please let us know. Thanks!

You can check out pingtunnel
Be aware that it's buggy and rips quite a bit of CPU.

WOW, that topic is absolutely new and amazing to me :O
Yeah, already checked it and it's only shared password.
Well we know what turns @yomero on now.
LOL
I am so excited xD
You can also tunnel over DNS :P
I used pingtunnel for years.
There is also http://code.kryo.se/iodine/ if your want to tunnel it through dns
@rewo: Have you tried pingtunnel and iodine authentication with mysql? Like multiple users have different usernames and passwords?
I do not think that any of these tools supports multiple users/passwords. I once used hans (http://code.gerade.org/hans/) which also only uses shared password.
hmmm, VPN providers must have been using non-openvpn software for it.. hmmm
If you are looking for an application that can tunnel through ICMP and DNS that uses mysql for authentication, I am sorry to tell you but you wont find one. You need to code it yourself if you really need it. I already searched for the same software before and ended up coding our own vpn server.
You can base your code on hans for icmp and iodine for dns. I am also guessing that you need it for windows so you also need to port the code for windows since hans is coded for linux only.
Quite the old thread you're bringing up!
But is very interesting
@Pinoy: I guessed so.. I've searched for that also.. and since I don't code, better luck next time.. Hehe
@yomero: Yeah, it is..
