Sto cercando di capire perchè se provo a collegarmi via ssh mi riesce solo usando la rete locale mentre se uso mioip.ddns.net mi da' sempre la stessa risposta:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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
7c:16:a9:75:44:c1:25:22:ce:f2:48:c5:35:de:8f:6d.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /root/.ssh/known_hosts:3
ECDSA host key for [vm5.ddns.net]:5678 has changed and you have requested strict checking.
Host key verification failed.
Ora se faccio ping sembra funzionare:
ping -c 5 ***.ddns.net -p 5678
PATTERN: 0x5678
PING ***.ddns.net (84.222.78.106) 56(84) bytes of data.
64 bytes from ***.ddns.net (84.222.78.106): icmp_req=1 ttl=64 time=0.575 ms
64 bytes from ***.ddns.net (84.222.78.106): icmp_req=5 ttl=64 time=0.595 ms
--- ***.ddns.net ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4004ms
rtt min/avg/max/mdev = 0.575/0.603/0.628/0.032 ms
Quindi non capisco cosa blocchi ssh. Ho anche provato a resettare ssh sul computer client :
ssh-keygen -R 192.168.1.108
purtroppo senza esito...
