I could not find my USB-to-DB9-to-RJ45 abomination if my life depended on it. This USB 2.0 100Mbit/s dongle had to suffice!

Ubiquiti EdgeRouter password reset

In case you lost your password as bad as you never knew it (well, there are perfectly legal cases for it, like if previous admin left without telling you the password) and you can't reset to defaults because you want to keep the old config intact, here's the method:

Connect to the router via serial and reboot it.

Press any key before the kernel starts booting.

If you see Octeon ubnt_e100# command prompt, you are in the bootloader (its U-Boot actually)

Issue the following command (it loads the kernel to RAM): fatload usb 0 $loadaddr vmlinux.64

When you see the propmt again, issue this command to start the kernel: bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rootdelay=15 rw rootsqimg=squashfs.img rootsqwdir=w init=/bin/bash mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)

When the kernel loads, you'll get an ordinary bash. Now generate a new password hash (for example for password "ubnt"): /usr/bin/mkpasswd --method=sha-512 ubnt

Open the startup config: vi /config/config.boot

Find a user entry under "system login" subtree. Replace the hash string after encrypted-password with the string generatd at previos step.

Now issue exit command. The kernel will be disappointed and go to reboot shortly.

After reboot you should be able to login with the user you edited and your new password.
