Python network configuration library
PyRoute2 uses Netlink protocol to communicate with the Linux kernel and get/set all the information kernel network objects.
- VLAN linkinfo data
- bridge info: see
./net/bridge/br_netlink.c:br_fill_ifinfo() - traffic control -- work with queue disciplines
Old-style library, that provides access to rtnetlink as is. It helps you to retrieve and change almost all the data, available through rtnetlink.
from pyroute2 import iproute
ip = iproute()
# lookup interface by name
dev = ip.link_lookup(ifname='tap0')[0]
# bring it down
ip.link('set', dev, state='down')
# change interface MAC address and rename it
ip.link('set', dev, address='00:11:22:33:44:55', ifname='vpn')
# add primary IP address
ip.addr('add', dev, address='10.0.0.1', mask=24)
# add secondary IP address
ip.addr('add', dev, address='10.0.0.2', mask=24)
# bring it up
ip.link('set', dev, state='up')
Experimental module, that provides high-level API to network configuration. It represents network objects as a transactional database with commit/rollback. It is far not production ready, so be prepared for surprises and API changes.
from pyroute2 import ipdb
ip = ipdb()
ip.tap0.down()
ip.tap0.address = '00:11:22:33:44:55'
ip.tap0.ifname = 'vpn'
ip.tap0.ipaddr.add(('10.0.0.1', 24))
ip.tap0.ipaddr.add(('10.0.0.2', 24))
ip.tap0.commit()
ip.vpn.up()
If you want to review and/or rollback the transaction, you can use code like that:
from pprint import pprint
...
pprint(ip.tap0.review())
{'attrs': {'address': 'da:72:48:6b:13:c8 -> 00:11:22:33:44:55',
'ifname': 'tap0 -> vpn'},
'ipaddr': ['+10.0.0.4/24',
'+10.0.0.5/24',
'+10.0.0.2/24',
'+10.0.0.3/24',
'+10.0.0.1/24']}
ip.tap0.rollback()
Actually, the form like 'ip.tap0.address' is an eye-candy. The ipdb objects are dictionaries, so you can write the code above as that:
ip['tap0'].down()
ip['tap0']['address'] = '00:11:22:33:44:55'
ip['tap0']['ifname'] = 'vpn'
...
Also, interface objects can operate as context managers:
with ip.tap0 as i:
i.address = '00:11:22:33:44:55'
i.ifname = 'vpn'
i.ipaddr.add(('10.0.0.1', 24))
i.ipaddr.add(('10.0.0.1', 24))
On exit, the context manager will authomatically commit the transaction.
All that you should know about taskstats, is that you should not use it. But if you have to, ok:
import os
from pyroute2 import taskstats
ts = taskstats()
ts.get_pid_stat(os.getpid())
It is not implemented normally yet, but some methods are already usable.
