Spread the love

DD-WRT Step 5 – SSH Access DDwrt router: setup your RSA and client key, configure Putty and discover your Linux kernel. Enabling SSHd allows you to access the Linux OS of your router with an SSH client (Putty works well on Windows, for example).

  • Password login – allow login with the router password (username is root)
  • SSHd Port – the port number for SSHd (default is 22)
  • Authorized Keys – here you paste your public keys to enable key-based login (more secure than a simple password)

Save and Apply

Personally, I use the same Private SSH key to access all my devices and IaaS servers on the cloud. Paired with Putty Agent, it’s so powerful and everything becomes password-free.

Setup Putty Client

These are just screenshots of Putty with basic setup to access DDwrt via SSH:

As you can see, a flash drive has been automatically mounted and will be used as external /opt holder for Entware.

Linux kernel:

uname -a

Linux ddwrt 4.4.215 #1052 SMP Wed Mar 4 12:16:22 +04 2020 armv7l DD-WRT

What’s at the root?

Wrapping up

Let’s move on to the next step 6: Format a Flash Drive with ext2 so you can install Entware on it!
