Reset root user password for Webmin
After updating my home server to the latest Ubuntu release (Natty / 11.04) I found almost everything worked properly apart from the the MDADM Raid 1 and Webmin refused to let me login. After some investigation, I found that my normal user was deleted. I reset the password via SSH using an included script.
Here's the command:
[geshifilter-pre] $ sudo /usr/share/webmin/changepass.pl /etc/webmin root new_password[/geshifilter-pre]
Then, logging in as root user to Webmin I could configure my normal user and all is right with the world!
