SECURITY

Due to the security concerns, in Debian we decided to disable default password authentication, and require to run ppserver with an non-trivial secret key (-s command line argument) which should be paired with the matching secret keyword of PP Server class constructor. An alternative way to set a secret key is by assigning pp_secret variable in the configuration file .pythonrc.py which should be located in the user home directory (please make this file readable and writable only by user). The secret key set in .pythonrc.py could be overridden by command line argument (for ppserver) and secret keyword (for PP Server class constructor). Note that passing the password on the command line allows every user to see it (e.g. using ps(1) ) and that running it on an open/untrusted network can be a security problem as traffic, including the password, is not encrypted.
