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 RSA key sent by the remote host is 86:10:55:0f:94:34:07:15:d8:1a:df:22:a5:4c:49:7e. Please contact your system administrator. Add correct host key in /root/.ssh/known_hosts to get rid of this message. Offending RSA key in /root/.ssh/known_hosts:1 RSA host key for 100.1.1.1 has changed and you have requested strict checking. Host key verification failed.
1. Run the following command to locate the file which contains the RSA finger print values for the all known hosts: root@240-2> file list /cf/root/.ssh /cf/root/.ssh: known_hosts 2. Delete the known host file from the database, so SRX can install the new RSA finger print value for the remote host. root@240-2> file delete /cf/root/.ssh/known_hosts
* If you are not root user, check /var/home/user01/.ssh/known_hosts .
