From e835aef3a0ebbc957abd38e54f8040f5b67157ce Mon Sep 17 00:00:00 2001 From: Thomas Mangin Date: Sat, 11 Apr 2020 14:27:57 +0100 Subject: ifconfig: T2223: rename Register to Section While the class does indeed all the registration, it work is really to map classes to interface section. ie: interface ethernet -> EthernetIf Therefore it can also list which interface are from which type, therefore the name change. Other function name will also be renamed as a consequence --- src/completion/list_openvpn_clients.py | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src') diff --git a/src/completion/list_openvpn_clients.py b/src/completion/list_openvpn_clients.py index 17b0c7008..177ac90c9 100755 --- a/src/completion/list_openvpn_clients.py +++ b/src/completion/list_openvpn_clients.py @@ -18,7 +18,7 @@ import os import sys import argparse -from vyos.ifconfig import Interface +from vyos.ifconfig import Section def get_client_from_interface(interface): clients = [] @@ -50,7 +50,7 @@ if __name__ == "__main__": if args.interface: clients = get_client_from_interface(args.interface) elif args.all: - for interface in Interface.listing("openvpn"): + for interface in Section.interfaces("openvpn"): clients += get_client_from_interface(interface) print(" ".join(clients)) -- cgit v1.2.3 From d3aa0bd68bb72bc35eb290b1c54cae4dfa4efb57 Mon Sep 17 00:00:00 2001 From: Thomas Mangin Date: Sat, 11 Apr 2020 14:43:28 +0100 Subject: ifconfig: T2223: rename Section.listing to interfaces update all code using the API.
