I know checking WAN uptime when using DHCP isn't usually straight forward, but I use PPPoE, and the reported WAN uptime on the status page is always accurate.
I was wondering if it's somehow possible to obtain this when logged in via SSH. For example, "uptime" displays the device uptime, so I was wondering if there's an equivalent command to display the WAN uptime.
As a quick manual check:
ifstatus wan | grep uptime
json_load "$(ifstatus wan)"
json_get_var wan_up up
json_get_var wan_uptime uptime
echo "wan is up: $wan_up"
echo "wan uptime: $wan_uptime"
Thanks. I get the following. I assume it's in seconds!
root@OpenWrt:~# ifstatus wan | grep uptime
