Optilink SSH login?

[.::IBF::..]

I can see the passwords inside the firmware upgrade script but cannot use it to login, any idea how to SSH into the router?

As of knowledge they did't enabled ssh insted they use Telnet for that. you can download putty on your pc and use the ip of your router and use this credentials for login. @.::IBF::..

Tried that does not work.

ssh -F /dev/null root:[email protected] -p23 -v

it seems to be you are using the port 23 (default telnet port) for ssh as per the log you shared here

ssh -F /dev/null root:[email protected] -p23 -v

.

on before that you better check this first "Common port filter"

And sure that using Telnet as shown below.

telnet doesn't work for me.
It does connect and shows the login prompts but after entering username and password it just closes the connection.

Maybe something with the firmware?

 

[Elavarasan]

Try differnt user name and password combination . changing of web log in password won't affect the telnet try the default one for your router

username: root
password: optilink

username: admin
password: Syro43210$

username: admin
password: admin

username: admin
password: stdONU101

username: admin
password: dbcONU101

i think password is the only issue because it is prompting you the login.so i conforms that telnet is enabled.

Here is my telnet login.

Oh thanks, you're right. It worked.

That's so dumb. Who codes these trash firmwares?

@.::IBF::.. you can use the 'sh' command in telnet to use the linux shell. It's almost a SSH experience.

That's such a huge security vulnerability. BSNL has instructed everyone to change the password but this makes it useless.
Now anyone can inject binaries and make botnet! This is so bad.
