summary: Check that `snap set {system,core} network.disable-ipv6` works
details: |
In Ubuntu Core systems network.disable-ipv6 core/system config can be used
to enable and disable the ip v6 protocol.
This test verifies that when network.disable-ipv6 core/system config is set
to true, then the ipv6 is disable in the system. Also it is verified that when
the config is set to false, then the ipv6 is enabled in the system.
environment:
snap_nick/system: system
snap_nick/core: core
execute: |
echo "Ensure we have inet6"
ip addr | MATCH inet6
echo "Disable ipv6"
# shellcheck disable=SC2154
snap set "$snap_nick" network.disable-ipv6=true
MATCH "net.ipv6.conf.all.disable_ipv6=1" < /etc/sysctl.d/10-snapd-network.conf
if ip addr | grep -q inet6; then
echo "Disable of ipv6 did not work"
ip addr
exit 1
fi
echo "Enable ipv6"
snap set "$snap_nick" network.disable-ipv6=false
not test -f /etc/sysctl.d/10-snapd-network.conf
sysctl net.ipv6.conf.all.disable_ipv6 | MATCH "net.ipv6.conf.all.disable_ipv6 = 0"
echo "Reset ipv6"
snap set "$snap_nick" network.disable-ipv6=""
not test -f /etc/sysctl.d/10-snapd-network.conf
