Mengganti port SSH CentOS 7


 


Langkah pertama ya edit konfigurasi daemon SSH:

nano /etc/ssh/sshd_config

Didalamnya gantikan portnya:

Port 12345

Nah sebenarnya disini ada satu tahap lagi, karena setahu saya CentOS 7 itu SELinux pasti aktif dan aturan defaultnya SSH itu hanya bisa lewat port 22. Jadi kita perlu tambahkan whitelistnya:

semanage port -a -t ssh_port_t -p tcp 12345

Akhirnya kita perlu instruksikan firewallnya agar port baru diatas diijinkan:

firewall-cmd --permanent --zone=public --add-port=12345/tcp

Setelahnya kita reload setting barunya:

firewall-cmd --reload

Baru kita restart proses SSH:

systemctl restart sshd.service


thats all.
