Allow and deny IP for ssh

We can allow and deny IP for ssh. To do this we have to change some configuration at /etc/host.deny and /etc/host.allow files. Suppose we want to deny 192.168.100.5, then we will edit the /etc/host.deny file and do some changes as follows.

vi /etc/host.deny

sshd:192.168.100.5

Save & exit

This will deny 192.168.100.5 to ssh.

Suppose we want to allow only 192.168.100.5 to ssh. Then we will edit two files as follows:

vi /etc/host.deny

sshd:all

save & exit

vi /etc/host.allow

sshd:192.168.100.5

save & exit

We can do the same by changing only at /etc/host.deny as follows:

vi /etc/host.deny

sshd:all except 192.168.100.5

save & exit
