moin, beim login auf den srv01 passierte heute # ssh srv01 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 a host key has just been changed. The fingerprint for the RSA key sent by the remote host is SHA256:LX0xpviTs3pSYWtibqspcjoqDDxrkzA1kw0F+4ZmXps. Please contact your system administrator. was ist hier los? The authenticity of host 'srv01.ffnw.de (37.120.176.207)' can't be established. RSA key fingerprint is SHA256:LX0xpviTs3pSYWtibqspcjoqDDxrkzA1kw0F+4ZmXps. RSA key fingerprint is MD5:97:7f:f3:b0:7f:57:04:d1:96:15:7f:eb:bc:de:17:6e. es macht sinn das man weiss das man sich auf den richtigen srv verbindet, wieso hat sich was am key geändert? wo stehen die fingerprints zum vergleichen? -- Freifunk Gruß pic Www: https://fr32k.de Xmpp: picard(a)fr32k.de & picard(a)ffnw.de Keybase: https://keybase.io/picard -- Gruß pic Xmpp: picard(a)ffnw.de & picard(a)fr32k.de @ME https://wiki.nordwest.freifunk.net/picard
