Network utilities

Lua RTOS has support for the following network services:

• ping
• scp put
• [scp putget(#netscpputhost-port-src-dst-user-password)
• ssh exec

net.ping(host)

The net.ping utility is used to test the reachability of a host on an Internet Protocol (IP) network. The host argument is a string with the host name o the host ip address.

Pinging can be interrupted pressing the Ctrl-c key.

net.scp.put(host, port, src, dst, user, password)

net.scp.get(host, port, src, dst, user, password)

net.ssh.exec(host, port, command line, user, password)
