Pyroute2 is a pure Python netlink library. It requires only Python stdlib, no 3rd party libraries. Later it can change, but the deps tree will remain as simple, as it is possible.
The library contains all you need to build either one-node, or distributed netlink-related solutions. It consists of two major parts:
More samples you can read in the project documentation. The lowest possible layer, simple socket interface. This socket supports normal socket API and can be used in poll/select:
from pyroute2 import IPRSocket
# create the socket
ip = IPRSocket()
# bind
ip.bind()
# get and parse a broadcast message
ip.get()
# close
ip.close()
Low-level iproute utility. The utility uses implicit threads, so notice ip.release() call – it is required to sync threads before exit:
from pyroute2 import IPRoute
# get access to the netlink socket
ip = IPRoute()
# print interfaces
print ip.get_links()
# stop working with netlink and release all sockets
ip.release()
High-level transactional interface, IPDB, release() call is also required:
from pyroute2 import IPDB
# local network settings
ip = IPDB()
# create bridge and add ports and addresses
# transaction will be started with `with` statement
# and will be committed at the end of the block
try:
with ip.create(kind='bridge', ifname='rhev') as i:
i.add_port(ip.interfaces.em1)
i.add_port(ip.interfaces.em2)
i.add_ip('10.0.0.2/24')
except Exception as e:
print(e)
finally:
ip.release()
The project contains several modules for different types of netlink messages, not only RTNL.
make install or pip install pyroute2
