are bad passwords and should be changed to something better (I have seen all of these passwords in use on real systems). Any variant of “letmein”, “password”, “remember”, etc.
#Change webmin port password
A strong password is one that is eight or more characters in length, has numbers or symbols and letters, and is not based on a dictionary word. (http. In Cloudflare, I created a firewall to block all requests for the webmin login page except requests that have a my computers ip address in the http.xforwardedfor field. 90% of systems that I’ve seen exploited have been because of weak passwords (the other 10% due to bugs in older versions of software–patched versions were available, but the system was running an unpatched version). I changed Webmins port from 10000 to one Cloudflare allows. Even better if you have a “real” certificate, or make sure you import the correct self-signed cert for your box…identity is about 50% of the value of SSL. Here we click on enp0s3 network interface for new IP address configuration. Then select Network Interfaces for setting up new IP address configuration. Here we just click on Network Configuration. Password time outs are in place for a reason (HTTP is stateless, so you can’t use the ssh technique of pausing on a bad password to reduce brute force attacks…you can only disable the account for a short time in the event of repeated bad passwords). We logged into Webmin clicked on Networking menu on the left panel.
At Edit Host Address change your IP Address by adding new ip address and click on Save Button. I’ve never had a Webmin installation compromised, and I’ve probably maintained more Webmin systems than 99% of people (my previous company had several hundred proxy caches in the field, all running Webmin), and the only precaution we took really seriously was updating within 24 hours of a new release–across all systems.ĭon’t disable the security features that are enabled by default. Following are the steps to change the IP Address of the domain in Webmin control panel.
Jamie has a great record of rolling out security fixes within a day or two, and sometimes even hours, of an exploit being exposed. Usermin is almost the same - just go into 'Usermin Coniguration' rather than 'Webmin Configuration'. you can change the Webmin/Virtualmin port there.
Make sure you’re always running the latest version. After you log into Virtualmin, click on Webmin -> Webmin -> Webmin Configuration -> Ports and Addresses. Since Webmin security has come up a few times over the past few days, I’ll mention a few aspects of keeping Webmin safe (similar to most root-level services, like ssh and ftp daemons…some extra caution is advised): Webmin doesn’t care what port it runs on (likewise for Usermin).
