Install GNU Stow to keep track of built-from-source-code applications using system default repository: sudo dnf install stow We install the following dependencies required for building sshguard application: sudo dnf install byacc flex gcc make We proceed to download sshguard 2.4.0 from sourceforge.net . We can then extract to default home location /home/username . Using terminal/console, set the location to the extracted folder using cd command: cd sshguard-2.4.0/ We proceed to build the sshguard using source makefile by running configure   with installation location set at /usr/local/stow/sshguard and make command: ./configure --prefix=/usr/local/stow/sshguard make We proceed to install the sshguard application using make install command: We edit the sshguard configuration file by setting backend executable file location at: BACKEND="/usr/local/libexec/sshg-fw-firewalld" We proceed to symlink the respective folders under /usr/local/stow/ssh

Setting up ssh restricted access to Edgerouter Introduction to Edgerouter's EdgeOS commands Running '?' shows commands available on EdgeOS in operational (upon logging in) and configuration mode ('configure' command) Running 'configure' allows us to go into configure mode Running 'commit' allows us to commit changes  Running 'commit-confirm' allows the change to take effect before reboot (important if you are unsure of the changes made and the impact to the system) Running 'save' allows us to save the change to persistent boot configuration Creating ssh key ssh-keygen Setting permission on .ssh and its subfolders chown -R username:usergroup .ssh/ Upload ssh key ssh-copy-id -i ~/.ssh/clienthost.pub username@routerhostname Loadkey  configure loadkey  commit save Limit ssh to listen to one address set service ssh listen-address 192.168.0.1   Follow my blog with Bloglovin
