Cara Login menggunakan SSH

ssh root@<ip_server>
ssh root@192.168.100

Gagal Login

Tidak mau Login saat menggunakan ssh, dan muncul seperti berikut :

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ED25519 key sent by the remote host is
SHA256:wQG2TeNasqvaMou+ldxltuPWE5vFqzQy8EbJd/NT6LQ.
Please contact your system administrator.
Add correct host key in /Users/akhyar/.ssh/known_hosts to get rid of this message.
Offending ED25519 key in /Users/akhyar/.ssh/known_hosts:17
ED25519 host key for 192.168.1.1 has changed and you have requested strict checking.
Host key verification failed.

Cara mengatasinya

Cara 1

Karena penulis menggunakan OSX, jadi edit file nano known_hosts, biasanya berada di dalam folder berikut :

/Users/Nama_User/.ssh/known_hosts atau /.ssh/known_hosts

Hapus baris yang terkait dengan IP server, misal :

192.168.1.7 ecdsa-sha2-nistp256 wQG2TeNasqvaMou+ldxltuPWE5vFqzQy8EbJd/NT6LQ

Login kembali menggunakan ssh

ssh root@192.168.1.100

Cara 2

Hapus file known_hosts

rm .ssh/khown_hosts

Login kembali menggunakan ssh

ssh root@192.168.100
