Many monitors use other Webmin modules to find the locations of the servers and daemons that they checked. Alternately, yo can check another system that does not have Webmin installed using the remote TCP, HTTP and ping monitor types. In the latter case the server must be defined in the Webmin Servers Index module, explained in chapter 53. (Which doesn't work when X completely freezes) I can't replicate this behavior on demand, it seems to occur more or less randomly. A monitor can run either on the system that you are using the module on, or another server running Webmin. But I don't think the system is dead becuase I can toggle numlock and scrolllock on and off. When I say "display locks up" I mean that, for some reason, either after boot or after I end a window manager session, my screen turns black and it looks like X is trying to restart but failing (there's a change in the shading on my monitor I associate with that) hitting control alt backspace doesn't help and trying to switch to one of the consoles doesn't work either. I will report back after trying to set this up. I don't really want to run webmin becuase I don't need to any remote administration besides rebooting, so webmin seems like overkill. Thanks, everybody for your suggestions, I will look more into an ssh key based-authentication. what I was doing was using "usermod -s " to try and change the shell and I was confused as to how to properly put the white space in you need to run the command "sudo reboot". I tried this, and it didn't work, I think it gave me "permission denied" errors, so I wonder if I got the syntax wrong. carlocci,:/home/carlocci:/bin/bash -c sudo shutdown now -r If this is the best answer, go ahead and tell me to rtfm, but first I'd like to know if there's a simpler solution.Ĭarlocci:x:1000:100:sig. I guess there might also be some way for me to set things up with chroot so that if you managed to login as "rebooter" you couldn't do anything meaningful besides reboot anyway, but I haven't looked into this yet. Is there maybe a better way to set this up? Maybe there's something I can do with the config to sshd to force login by the "rebooter" to force a reboot? So it seems like in princple you could make this work, I'm just doing somthing wrong.īut this raises another question, could I still manage to login to bash by interupting this script? I don't think so, becuase in this instance bash is not running interactively, please tell me if I"m wrong. Type the following command to remove webmin under FreeBSD operating system: cd /usr/ports/sysutils/webmin make deinstall clean OR use pkgdelete command: pkgdelete webmin A Note About Firewall Configuration You may need to update your pf or netfilter scripts to close port 10000 which was opened for webmin. (My sudoers file allows the user "rebooter" to run reboot w/o a passwd). And using that script as the login shell for the dedicated reboot user ("rebooter"), but I would get a permission denied error when I tried to login as the user then. Beside Password, select Don’t change and choose Set to.On the left, select Webmin, then Webmin Users.You can also reset your server root user password in AMP. Beside Password, select the drop-down and choose Set to.Change your password with the steps below if the command shows within your bash history – history.Ubuntu users, add a space before the command so it doesn’t save in your bash history. Reset your Webmin password with the changepass program:.Remember, this is base free software that has not been configured for your server. We recommend using separate user credentials for Webmin, at least until you’ve taken steps to harden Webmin security. Setting a root password for Webmin disconnects your Webmin user credentials from your server root user. I finally got it to stop overwriting my nf by putting the line 'nohook nf' into my /etc/nf file. Commenting-out the options for domainnameservers and domainsearch in /etc/nf did not help. By default, your Webmin password uses your server root credentials (Unix authentication). On reboot I always got a new nf with 'domain openstacklocal' and the OVH DNS server. Next, I have installed Webmin on the VM (using the RPM method). There are multiple ways to reset your Webmin password. I have just installed a CentOS 9 Stream VM. Visit your Webmin at hostname:10000 or ServerIP:10000 with your root user credentials.In this article:ĭon’t prefer CentOS? Use Debian or Ubuntu instead with our scalable Cloud Server Hosting plans. You need to use best practices for password strength and security. Just like cPanel and other alternative control panels, Webmin grants privileged users access to important data, analytics, and more on the server with a graphical interface. After you install Webmin on CentOS or another operating system (OS), you’ll need to understand how to manage root and Webmin user passwords.
