<br>
I'll just repeat my forum entry here - just do not know, if some DEVs read<br>
them ;-)<br>
<br>
<br>
I just try to find a way, where I can run a webbrowser in a more isolated<br>
environment.<br>
This ends most of the time in running it inside a LXC container or such.<br>
<br>
Also this is really a bit complex, there is probably a easier way using<br>
'cgroups'<br>
which is about limiting resources, like networks/filesystems etc. pp.<br>
Example:<br>
<br>
Per process routing2:<br>
<a href="http://www.evolware.org/?p=369" rel="noreferrer" target="_blank">http://www.evolware.org/?p=369</a><br>
<br>
Using linux namespaces for processes and networking:<br>
<a href="http://www.evolware.org/?p=369" rel="noreferrer" target="_blank">http://www.evolware.org/?p=369</a><br>
<br>
If one can put processes into a cgroup, one can give them a custom routing<br>
oder even<br>
ip-address, which is much easier to filter, ether locally (with iptables) or<br>
at the firewall.<br>
<br>
So a very wonderful hit could be, to start all processes inside a given XFCE<br>
workspace<br>
inside a separate cgroup. For this case, a colored border of such a<br>
workspace could give<br>
a good extra hint to remember. But this could make the network manager<br>
complex.<br>
<br>
I am, sorry, not that type of linux insider, that I [currently ;-) ] could<br>
do this by<br>
myself. Just a thinking about the future of XFCE ... ;-)<br>
<br>
Comments are welcome too!<br>
<br>
Best regards,<br>
Manfred<br>
