98-mylog is just for debugging purposes
tail -f /tmp/mylog would keep you updated

For interface names ,
ls /sys/class/net ...
In my case in 14.07,
Interface wan6 was for pppoe

Thank you!

operstate is on my interface always unknown - also when it is connected.

I'm new guy for openwrt and github too. I read your script is awesome!
I hope you can help me if I want to connect l2tp over ipsec client when WAN was connected.
How can I do it with hotplug iface script?
The l2tp over ipsec config was done and I can connect it use command. But it will discount after every 12 hours.
So I want to use hotplug to reconnect it if it is possibale!
Thanks a lot!

Here is my command code for l2tp
/etc/init.d/ipsec enable
/etc/init.d/xl2tpd enable
/etc/init.d/ipsec restart
/etc/init.d/xl2tpd restart
ipsec restart
ipsec up L2TP-PSK
ipsec statusall
echo "c strong-vpn" > /var/run/xl2tpd/l2tp-control
