From 7dbaa25a199a781aaa9f269741547e576410cb11 Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Thu, 28 Mar 2024 07:36:22 +0100 Subject: op-mode: T6175: "renew dhcp interface " does not check for DHCP interface The current op-mode script simply calls sudo systemctl restart "dhclient@$4.service" with no additional information about a client interface at all. This results in useless dhclient processes root 47812 4.7 0.0 5848 3584 ? Ss 00:30 0:00 /sbin/dhclient -4 -d root 48121 0.0 0.0 4188 3072 ?

This commit moved the renew command to the DHCP op-mode script to properly validate if the interface we request a renew for, has actually a dhcp address configured. In additional this exposes the renew feature to the API. --- data/templates/dhcp-client/override.conf.j2 | 3 --- 1 file changed, 3 deletions(-) (limited to 'data/templates/dhcp-client/override.conf.j2') diff --git a/data/templates/dhcp-client/override.conf.j2 b/data/templates/dhcp-client/override.conf.j2 index d09320270..c2e059c7b 100644 --- a/data/templates/dhcp-client/override.conf.j2 +++ b/data/templates/dhcp-client/override.conf.j2 @@ -3,9 +3,6 @@ {% set if_metric = '-e IF_METRIC=' ~ dhcp_options.default_route_distance if dhcp_options.default_route_distance is vyos_defined else '' %} {% set dhclient_options = '-d -nw -cf ' ~ isc_dhclient_dir ~ '/dhclient_' ~ ifname ~ '.conf -pf ' ~ isc_dhclient_dir ~ '/dhclient_' ~ ifname ~ '.pid -lf ' ~ isc_dhclient_dir ~ '/dhclient_' ~ ifname ~ '.leases ' ~ if_metric %} -[Unit] -ConditionPathExists={{ isc_dhclient_dir }}/dhclient_%i.conf - [Service] ExecStart= ExecStart={{ vrf_command }}/sbin/dhclient -4 {{ dhclient_options }} {{ ifname }} -- cgit v1.2.3
