How do I login to the DD-WRT via SSH?

The DD-WRT firmware can use user/pass logon or only allows connections from clients whose public keys are manually entered via the web interface. Multiple keys can be entered by placing them on separate lines. If you want to use user/password to login using SSH use user "root" with the password you set in the webinterface

What is the default port for DD-WRT to auto login?

This is useful when you need dd-wrt to auto-login to another host via SSH. Choose a random, non-standard port number >1024, especially if you enabled SSH access from the Internet! Most attackers will use a port scanner that only scans for common open ports by default.

What is remote SSH management and how do I enable it?

This feature makes it possible to connect securely to the router's HTTP web interface, even when the interface has been configured to only be accessible by computers on the router's LAN.

What is remote SSH?

SSH or Secure Shell is a network protocol that connects users to a remote computer over a secure connection. This allows administrators and other authorized users to connect to secure computers over a network that is not secure, like the Internet. This is accomplished through the use of encryption.

DresDren-Wireless RouTerWhat Does DD-WRT Mean? DD-WRT (DresDren-Wireless RouTer) is a type of firmware for routers based on the Linux kernel. It was designed especially for 802.11a/b/g/h/n routers having the Broadcom or Atheros chipsets.

Why DD-WRT is better?

Essentially, it echoes the signal to widen its range. With DD-WRT, you can take a regular router and make it into a range extender. A stronger, better, optimized DD-WRT signal may also be able to more easily reach farther devices, even without a range extender.

For the latter to work, a small public key is given to the server and the server gives your client its public key. Your client encrypts information to the server using the servers public key and the server encrypts information sent to you using your public key. Private keys are never exchanged, and are used to decrypt the information encrypted with the associated public key.

Can DD-WRT use user/pass?

The DD-WRT firmware can use user/pass logon or only allows connections from clients whose public keys are manually entered via the web interface. Multiple keys can be entered by placing them on separate lines.

Authentication

We'll start with an optional part first; the key pair. So you understand, you have 3 options when it comes to authenticating to your router:

Router Configuration

Go to " Services " and then the " Services " sub-tab and scroll down to where you see " Secure Shell "

Loopback Adapter Configuration

Note: this is only required if you want to enable Windows file sharing.

PuTTY Configuration

Open PuTTY and it will bring you to the Session options. Enter your IP or DDNS information and the listening port. You can come back to this area when your done configuring PuTTY and save the options as well so you don't have to type them in every time.

Browser Configuration & Drive Mapping

Configure IE for Internet browsing (understand that all Internet traffic will be re-directed through your SSH tunnel, but DNS requests won't):

More Encryption

If you created a key pair you may want to have it available at all times. What I did was use a free program called Jetico BestCrypt Traveller, which requires no installation at all which makes it perfect for use on all computers. It creates encrypted containers that I then put my key and PuTTY in and store it on the web.

Is SSH tunneling secure?

Does SSH tunnel work for RDP?

I use the SSH tunnel a lot so I don't have to open many ports to the world, and like you said the entire connection is encrypted. It works well for RDP connections as well. I also like the ability to use the router as a proxy server through the SSH tunnel. Most networks allow port 22 through.

Big vs Mega-Are they Swapped or is Big just the Ultimate adjective

So, I been seeing this around the forums for a while with people asking why the DDWRT Big ( dd-wrt.v24-44715_NEWD-2_K3.x_big.bin ) [24.9MB] file is so much larger than the Mega file. ( dd-wrt.v24-44715_NEWD-2_K3.x_mega.bin ) [7.25MB] I am a newbie to this so I can't speak from authority, but as far as I can tell they seem to be swapped.
