This has been confirmed to work for, at the very least, my own Verizon Fi-OS
|
||
|
Actiontec MI424WR-GEN3I on firmware 40.21.24. It might work on other models as
|
||
|
well, but this hasn't been tested.
|
||
|
|
||
|
No non-stdlib modules are required.
|
||
|
|
||
|
Place your routers credentials in ~/.config/optools/actiontec_mgmt.json
|
||
|
in the following format:
|
||
|
(pay close attention to the quoting)
|
||
|
(minified json is OK/whitespace-insensitive):
|
||
|
_______________________________________________________________________________
|
||
|
{
|
||
|
"ip_addr": "192.168.1.1",
|
||
|
"user": "admin",
|
||
|
"password": "admin",
|
||
|
"ssl": false,
|
||
|
"port": 23
|
||
|
}
|
||
|
_______________________________________________________________________________
|
||
|
|
||
|
IF:
|
||
|
|
||
|
- That file isn't found:
|
||
|
-- A default (blank) one will be created (with secure permissions). All values
|
||
|
will be null (see below).
|
||
|
|
||
|
- "ip_addr" is null:
|
||
|
-- You will be prompted for the IP address interactively. (If you don't know
|
||
|
the IP address of it, it's probably the default -- "192.168.1.1".)
|
||
|
|
||
|
- "user" is null:
|
||
|
-- You will be prompted for the username to log in interactively. (If you don't
|
||
|
know the username, it's probably the default -- "admin".)
|
||
|
|
||
|
- "password" is null:
|
||
|
-- You will be prompted for the password. When being prompted, it will NOT echo
|
||
|
back (like a sudo prompt).
|
||
|
|
||
|
- "ssl" is null:
|
||
|
-- The default (false) will be used.
|
||
|
|
||
|
- "port" is null:
|
||
|
-- The default port (23) will be used.
|
||
|
|
||
|
|
||
|
|
||
|
TIPS:
|
||
|
|
||
|
- You need to ensure that you have the management interface enabled. Log into
|
||
|
your Actiontec's web interface, and:
|
||
|
1.) "Advanced" button (at the top)
|
||
|
2.) "Yes" button
|
||
|
3.) a.) Choose "Local administration" if you'll be managing the device within
|
||
|
the network it provides.[0]
|
||
|
b.) Choose "Remote administration" if you'll be managing the device
|
||
|
outside the network it provides (i.e. over the Internet).[0]
|
||
|
3.5) The "Telnet" options are what you want, ignore the "Web" settings.
|
||
|
4.) Select the protocols/ports you'll be using. SEE FOOTNOTE 0 ([0])!
|
||
|
5.) Click the "Apply" button.
|
||
|
|
||
|
- "ip_addr" can also be a host/DNS name -- just make sure it resolves on your
|
||
|
local machine to your Actiontec IP address! The default, at least on mine,
|
||
|
was "wireless_broadband_router" (can be changed via Advanced > Yes > System
|
||
|
Settings > Wireless Broadband Router's Hostname):
|
||
|
|
||
|
[bts@cylon ~]$ nslookup wireless_broadband_router 192.168.1.1
|
||
|
Server: 192.168.1.1
|
||
|
Address: 192.168.1.1#53
|
||
|
|
||
|
Name: wireless_broadband_router
|
||
|
Address: 192.168.1.1
|
||
|
Name: wireless_broadband_router
|
||
|
Address: <YOUR_PUBLIC_IP_ADDRESS>
|
||
|
|
||
|
|
||
|
- Unfortunately it's a necessity to store the password in plaintext currently.
|
||
|
Future versions may give the option of encrypting it via GPG and using an
|
||
|
existing GPG agent session to unlock (if there's demand for such a feature).
|
||
|
Make sure your machine's files are safe (I recommend full-disk encryption).

[0] NOTE: ENABLING MANAGEMENT CAN BE HIGHLY INSECURE, *ESPECIALLY* IF ENABLING
|
||
|
"REMOTE ADMINISTRATION"! *ONLY* DO THIS IF YOU UNDERSTAND THE RISKS
|
||
|
AND HAVE ACCOUNTED FOR THEM. TELNET PASSES CREDENTIALS IN PLAINTEXT
|
||
|
BY DEFAULT, AND IF SOMEONE NASTY GETS THEIR HANDS ON YOUR DEVICE'S
|
||
|
CREDENTIALS THEY CAN DO *VERY* NASTY THINGS. I REFUSE ANY AND ALL
|

|
LIABILITY YOU OPEN YOURSELF UP TO BY ENABLING THIS. AT *LEAST* USE
|
||
|
THE "USING SECURE TELNET OVER SSL PORT"[1] OPTION.
|

YOU HAVE BEEN WARNED.

and it uses VERY weak ciphers, at that:

It's generally probably not even worth it, to be honest. You'll get
|
||
|
more security mileage out of firewalling off to select hosts/nets.
|
||
|
But, if you insist on having it and using it, you will ALSO need to
|
||
|
install the following module:
|
||
|
|
||
|
ssltelnet
