Simple library for controlling PPP connections with pppd.

Project description

Simple library for controlling PPP connections with pppd. Under the hood it uses the subprocess module to interact with pppd to create and disconnect PPP connections. Positional and keyword arguments are passed to the pppd command- line although there is protection for shell exploits.

This library has been production tested connecting daily to 280+ remote locations via dial-up PPP connection for over a year. I have simply packaged and cleaned up the module as some may find it useful.

Anyone wanting to do something similar in a Windows environment should probably take a look at win32ras.


You will require pppd, the PPP daemon and PPP kernel modules.


To install simply:

pip install python-pppd

Alternatively, install from the repository:

git clone cd python-pppd python install

Getting Started

You can connect to an existing configured PPP connection:

>>> from pppd import PPPConnection
>>> ppp = PPPConnection(call='work') # blocks until connected
>>> ppp.connected() # check if connected, raises error if connection error
>>> ppp.laddr # address of local host
>>> ppp.raddr # address of remote client

You can specify any positional or keyword arguments:

PPPConnection('/dev/ttyS0', connect='/usr/bin/chat -v -f /etc/chatscripts/A1')

Which is equivalent to the following:

sudo pppd /dev/ttyS0 connect “/usr/bin/chat -v -f /etc/chatscripts/A1”

Normally you require sudo to use pppd, if you don’t have it and have setup the pppd binary with setuid-root or are running as root you can use:


You can also specify an alternate paths to pppd or sudo if the libary cannot find them:

PPPConnection(sudo_path='/usr/local/bin/sudo', pppd_path='/usr/local/sbin/pppd')
