This is a proof-of-concept implementation how we can listen for netlink messages and process them in Python. Python 3.10 minimum is required due to the use of case statements which mimics C-style switch/case instructions. Add example: set interfaces ethernet eth1 vif 21 address dhcp set interfaces ethernet eth1 vif 21 address dhcpv6 commit If network cable is unplugged: vyos-netlinkd[12681]: RTM_NEWLINK -> eth3.10, state=DOWN, mac=00:50:56:b3:9d:8e vyos-netlinkd[12681]: Stopping dhclient@eth3.10.service... vyos-netlinkd[12681]: Stopping dhcp6c@eth3.10.service...

The helpers are: * /etc/netplug/linkdown.d/dhclient * /etc/netplug/linkup.d/dhclient As those helpers use Linux actions to start/restart the dhclient process in Perl it's time to rewrite it. First goal is to get rid of all Perl code and the second is that we now have a Proper Python library. Instead of checking if the process is running the then restarting it without even systemd noticing (yeah we might get two processes beeing alive) we should: * Add a Python helper that can be used for both up and down (see man 8 netplugd FILES section) * Query the VyOS CLI config if the interface in question has DHCP(v6) configured and is not disabled * Add IPv6 DHCPv6 support MAN page: https://linux.die.net/man/8/netplugd 2021-06-13T14:22:19+00:00 Christian Poessinger christian@poessinger.com 2021-06-13T14:20:13+00:00 urn:sha1:c40dd177b1ab62e311aa8c94e8032ca3b57fd934 Commit 945300c6f5 ("snmp: mibs: import from vyatta-cfg-system") imported the MIBs from vyatta-cfg-system and provided them with a symlink to /usr/share/vyos/mibs. The symlink was never installed as the directory already existed. Adjust the MIBDIRS environment variable to load the MIBs from the proper VyOS folder and use no symlink at all. 2021-05-20T19:34:16+00:00 Christian Poessinger christian@poessinger.com 2021-05-20T19:34:16+00:00 urn:sha1:945300c6f5f86b2381e5621ba00f8f70137b98b0
