Did not "nvram get http_passwd" going from DD-WRT to Tomato

    I decided to go from DD-WRT to Tomato firmware on my WRT54G, however, I didn't catch the fact I needed to get the encrypted password using "nvram get http_passwd" first. Now I have a router that I can get a login window for but I don't know what the password is.

    I am hoping somebody knows of a way to reset the password or decode the password. Any advice would be appreciated.

    Push in the reset button for like a minute, and I think it'll clear nvram, dunno for sure.

    If the reset doesn't work just reflash dd-wrt then get the password. Flash Tomato again and you should be able to get it working. I have been down this road in the past as well.

    ...30 seconds should be plenty

    Thanks for the responses so far. The reset for 30+ seconds didn't work so now I am trying to reflash the DD-WRT firmware. I poked around and found this command.

    TFTP -i PUT c:\ddwrtstd.bin

    (I renamed the bin file to be easier to reference on the TFTP command and put it right in my root c:\ drive).

    I am getting this message: "Timout Occurred"

    Is there another way to "reflash" the router from a command line?

    If I recall correctly, for the full "factory defaults reset" to work, you have to be holding the reset button for 30 seconds at power-on. So unplug the power to your router, hold down the reset button, plug the power back in, and release the reset button after 30 seconds or so.

    The 30 second reset will not work switching from dd-wrt to Tomato. You need the encrypted password

    Just one more reason to always reset to defaults BOTH before AND after a firmware upgrade of any type.

    Amazing how many "helpful" suggestions of "try this" ("but I don't actually *know* what I'm talking about, and after all, it's your router, your time, and your happiness"). :rolleyes:

    No one seems to have considered (suggesting) reading the *entire* paragraph in the wiki entitled

    Before the Upgrade

    here's the link:




    (This has an error: it puts a shell on port 233 not 23.)

    Or simply reading the GUI page under Administration > Buttons/LED

    Follow this and you won't fail. From Tomato FAQ


    Why doesn't my password work?

    Make sure you're entering the username "admin" or "root". Unlike the Linksys firmware, they are required in Tomato.

    If you're upgrading from the DD-WRT firmware, telnet into the router *before* upgrading and type "nvram get http_passwd". The result will be your password in Tomato. This is necessary because of a change in DD-WRT's way of using the standard http_passwd variable.

    If you have a Buffalo router or a Linksys with a pushable Cisco logo, push the AOSS/Cisco button for at least 20 seconds, then telnet into the router on port 233. Type "nvram get http_passwd" to retrieve the password or "nvram set http_passwd='your_new_password'" followed by "nvram commit" to set it manually. Reboot the router using the command "reboot" after using this method.

    Doesn't always work
    If nothing else works, push the reset button for a few seconds to reset all of the settings. The default password after resetting is "admin".

    There is another way to get this... If you run linux AND you have a backup of your configuration type: strings <backupfile.bin> find the line that says http_passwd" then copy the line directly below that. This is the same thing.
