Sshd Permitroot Login
When I was testing my new FreeBSD 10 RC, I was not able to connect from remote machine using root user. So I decided to make a tutorial about this, may be it will help some people who is having the same problem. [email protected]:~ # /etc/rc.d/sshd restart Performing sanity check on sshd
Find the "PermitRootLogin" line in sshd_config: #PermitRootLogin yes. Uncomment it and change the value to "no": PermitRootLogin no. Save configuration file and restart SSH service. 3. Only use SSH Protocol 2. Since SSH protocol 1 is insecure we need to force SSH server to always use protocol 2.
As what we wrote in the previous article on how to allow SSH root on Ubuntu 14.04, after installing a fresh new copy of Ubuntu 16.04 LTS, we find that once again (for better security) ssh root access has been configured to "prohibit-password" by default.This prevents root login via SSH. Before you begin the following steps, make sure you first enabled root password.
If Ubuntu has the root account locked by default, why does /etc/ssh/sshd_config have "PermitRootLogin yes" in the default config? Isn't that a security risk allowing the root account to login by default? If Ubuntu users have to specifically enable the root account then I don't think its too much extra effort to allow root ssh login if they really require it.
15.4. Configure the /etc/ssh/sshd_config file The /etc/ssh/sshd_config file is the system-wide configuration file for OpenSSH which allows you to set options that modify the operation of the daemon. This file contains keyword-value pairs, one per line, with keywords being case insensitive.
SSH root login is disabled by default in Ubuntu 18.04. SSH server for Ubuntu provides by the openssh-server package and root login is controlled by the PermitRootLogin directive in the OpenSSH server configuration (sshd_config file):. You can check the current status by running the following command:
