SSH CONNECTION PROBLEM “WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!”


Palangka Raya, 5 Ramadhan 1432 H

#ssh -Y admin@1.1.1.1
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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 ECDSA key sent by the remote host is
ee:0a:f6:e3:6a:ff:c1:97:43:b0:c5:f1:da:ab:3c. please contact your system administrator.

1. Kemungkinan terjadi perubahan ip address pada interfaces yang dipakai baik eth maupun wlan
2. Cara yang tercepat adalah menghapus directory dan file didalamnya “/root/.ssh/known_hosts”

#rm -r /root/.ssh

3. Coba lagi koneksi ssh

#ssh -Y admin@1.1.1.1
The authenticity of host ‘1.1.1.1 (1.1.1.1)’ can’t be established.
DSA key fingerprint is a3:61:c8:f1:de:8e:63:47:8b:d4:ba:50:ac:10:11:ad.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘1.1.1.1’ (DSA) to the list of known hosts.
admin@1.1.1.1’s password:

Alhamdulillah, koneksi via ssh berhasil.
