I am trying to execute ssh commands through camel route. I am getting below error can anyone help me to resolve the issue. I was able to execute commands by using username and password.
public key I copied in authorized_keys in server. I am using blueprint dsl.
< to uri="ssh://[email protected]:22? certResource=classpath:test_rsa&timeout=5000"/>
test_rsa is the filename where public key is present.
Server at /10.23.24.41:22 presented unverified DSA key:
8a:40:91:2a:16:90:8c:c4:06:b1:1f:79:74:2f:08:09

Instead of certResource=classpath:test_rsa, try: privateKeyFile=/path/to/test_rsa
< to uri="ssh://[email protected]:22?privateKeyFile=/path/to/test_rsa & amp; knownHostsFile=/path/to/known_hosts"/>
your known_hosts file can be empty initially. this worked for me. Hope this helps!
