SSH from VDX issue

Dear community,


I am not able to SSH from a VDX switch to a remote server, due to following issue:


my_vdx# ssh -l my_user @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is c7:6b:2e:f4:6e:64:4b:22:8b:58:be:28:17:ef:c7:a4. Please contact your system administrator. Add correct host key in /root/.ssh/known_hosts to get rid of this message. Offending key in /root/.ssh/known_hosts:1 RSA host key for has changed and you have requested strict checking. Host key verification failed.


How can I "clean/delete" the known_hosts file on a VDX switch (in VCS mode)?


Best Regards,
