Inexperienced Debian administrator here with a question about how to maintain the new obfsproxy/Tor for ScrambleSuit. I installed as follows:

1. Updated /etc/apt/sources.list (new lines prefixed with *):

deb http://server.name.redacted/debian wheezy main contrib non-free *deb http://server.name.redacted/debian unstable main contrib non-free deb http://server.name.redacted/debian-security wheezy/updates main contrib non-free deb http://deb.torproject.org/torproject.org wheezy main *deb http://deb.torproject.org/torproject.org tor-nightly-master-wheezy main

2. Created apt.conf to prevent all packages from being pulled from

unstable by default:

echo 'APT::Default-Release "stable";' > /etc/apt/apt.conf

3. Edited torrc with following:

ServerTransportPlugin obfs3,scramblesuit exec /usr/bin/obfsproxy managed

4. Installed the new packages:

apt-get update apt-get -t unstable install obfsproxy apt-get upgrade <-- Installed Tor nightly.

5. service restart tor

My question:

Is there a way to configure things so obfsproxy and Tor will later automatically be upgraded to a *stable* release that includes ScrambleSuit? And how to know when I need to upgrade obfsproxy and Tor?

Hello Delton,

you will need to wait till tor-0.2.5.1 becomes stable if you want to use scramblesuit with a stable Tor. Till then, please keep on using Tor nightlies.

As far as your second question goes, unfortunately we don't have good upgrade processes yet. I suggest you do 'apt-get upgrade' every once in a while to get the latest nightlies of obfsproxy/tor. If there are any urgent upgrades that you need to perform I will send an email to tor-relays.

Feel free to ask any other questions you have.
