Tente excluir a linha 5 em /root/.ssh/known_hosts!
EDIT: Por favor, considere o que @FrankThomas disse nos comentários à sua pergunta
Eu recebo este erro depois de ativar o ssh no switch Cisco.

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
a6:90:00:e1:b2:05:75:ce:48:ed:15:10:bd:51:90:a2.
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:5
RSA host key for 172.10.77.126 has changed and you have requested strict checking.
Host key verification failed.
Como posso acessar o switch da caixa linux? Parece que eu preciso copiar a chave pública do cisco switch para /root/.ssh/known_host mas de onde posso obter a chave pública no cisco router
