Telnet access - jamesmacwhite/hh70-ee GitHub Wiki
A custom script called oem_start.sh
is responsible for starting the key custom services mainly /usr/bin/core_app
and /usr/bin/webs
. In this script the value of the firmware env var of enable_telnet
is checked. If it is set to 0
, the telnet daemon is stopped. There is a short window where the telnet daemon may be active before this script stops the daemon process. You can set this env var to 1 to enable telnet permanently.

The enable_telnet
environment variable can be set through fw_setenv with:
fw_setenv enable_telnet 1
