how to know current ip and gateway?

[admin]

Use this:

Code:

routes = io.readproc('route')
gateway = routes:match('default%s+([%d%.]+)')

ifinfo = require('ifinfo')()
ip = ifinfo.eth0.inetaddr

log(ip, gateway)

If DHCP is used it is highly recommended to use a static IP-MAC binding so LM IP cannot change randomly.
