Python SSH (paramiko)
Så jag försöker att ansluta via SSH till en cisco switch.
C:\Users\Frejoh466\Desktop\Python>connect.py
C:\Python27\lib\site-packages\paramiko\client.py:837: UserWarning: Unknown ssh-rsa host key for xx.xx.xx.xx: 984b3c6d1039b83057d795a816a48215
key.get_name(), hostname, hexlify(key.get_fingerprint())
C:\Users\Frejoh466\Desktop\Python>
Det fungerar fint när jag ansluter på en switch i nätverket, men när jag ansluter direkt så fungerar det inte
C:\Users\Frejoh466\Desktop\Python>connect.py

Någon som vet varför det inte fungerar när jag ansluter direkt till cisco switchen?
