[Devil-Linux-discuss] how to setup DL firewall to block "teamviewer"

[Gudy <jaz...@gm...>]

Sir ,
I'm using DL now for more then a year, no serious issues :)))))))
As i only have a small business,I just figured out my staff is bypassing  
my dl firewall by using teamviewer!
they have complete remote control access over all files and pc's which are  
running windows
so stealing confidential information is very easy(white collar criminals!!)
I've seen on the web they even have teamviewer for linux... so also linux  
pc's are vulnerable

I have no idea how to block this

If one of you have a solution,please let me know

best regards

It seems it uses ports 80/443 (http/https) ports and so is hard to block with
firewall.  Seems you need to use squid.  I got that from this link:

http://forum.pfsense.org/index.php/topic,22632.0.html

It's a start anyway

It sounds easier to do the DNS approach, also mentioned in the link.

[Gudy <jaz...@gm...>]

be sure i've read all information in the the link.... and there are more  
teamviewer alike programs to be aware of
one of the issues is ,teamviewer not need any installation, just copy and  
start it
i found it on the accountants pc!

best regards
