Hallo, ich hab vorhing mal SSH upgedatet so wie in CVE-2024-6387 empfohlen Siehe: https://ubuntu.com/blog/ubuntu-regresshion-security-fix
Das habe ich dann mit dem Befehl gemacht:
sudo apt update && sudo apt install openssh-server
Anschliessend habe ich die SSH-Version nochmal geprüft, hat sich aber nix geändert:
ssh -v localhost OpenSSH_8.9p1 Ubuntu-3ubuntu0.10, OpenSSL 3.0.2 15 Mar 2022 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: include /etc/ssh/ssh_config.d/*.conf matched no files debug1: /etc/ssh/ssh_config line 21: Applying options for * debug1: Connecting to localhost [127.0.0.1] port 22. debug1: Connection established. debug1: identity file /home/USERNAME/.ssh/id_rsa type -1 debug1: identity file /home/USERNAME/.ssh/id_rsa-cert type -1 debug1: identity file /home/USERNAME/.ssh/id_ecdsa type -1 debug1: identity file /home/USERNAME/.ssh/id_ecdsa-cert type -1 debug1: identity file /home/USERNAME/.ssh/id_ecdsa_sk type -1 debug1: identity file /home/USERNAME/.ssh/id_ecdsa_sk-cert type -1 debug1: identity file /home/USERNAME/.ssh/id_ed25519 type -1 debug1: identity file /home/USERNAME/.ssh/id_ed25519-cert type -1 debug1: identity file /home/USERNAME/.ssh/id_ed25519_sk type -1 debug1: identity file /home/USERNAME/.ssh/id_ed25519_sk-cert type -1 debug1: identity file /home/USERNAME/.ssh/id_xmss type -1 debug1: identity file /home/USERNAME/.ssh/id_xmss-cert type -1 debug1: identity file /home/USERNAME/.ssh/id_dsa type -1 debug1: identity file /home/USERNAME/.ssh/id_dsa-cert type -1 debug1: Local version string SSH-2.0-OpenSSH_8.9p1 Ubuntu-3ubuntu0.10 debug1: Remote protocol version 2.0, remote software version OpenSSH_8.9p1 Ubuntu-3ubuntu0.10 debug1: compat_banner: match: OpenSSH_8.9p1 Ubuntu-3ubuntu0.10 pat OpenSSH* compat 0x04000000 debug1: Authenticating to localhost:22 as 'USERNAME' debug1: load_hostkeys: fopen /home/USERNAME/.ssh/known_hosts: No such file or directory debug1: load_hostkeys: fopen /home/USERNAME/.ssh/known_hosts2: No such file or directory debug1: load_hostkeys: fopen /etc/ssh/ssh_known_hosts: No such file or directory debug1: load_hostkeys: fopen /etc/ssh/ssh_known_hosts2: No such file or directory debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: algorithm: curve25519-sha256 debug1: kex: host key algorithm: ssh-ed25519 debug1: kex: server->client cipher: chacha20-poly1305@openssh.com MAC: <implicit> compression: none debug1: kex: client->server cipher: chacha20-poly1305@openssh.com MAC: <implicit> compression: none debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: SSH2_MSG_KEX_ECDH_REPLY received debug1: Server host key: ssh-ed25519 SHA256:QZUEoYDp5n9OR3uBwmzVZKYVGB0+uPcU9tfBFfTNN5g debug1: load_hostkeys: fopen /home/USERNAME/.ssh/known_hosts: No such file or directory debug1: load_hostkeys: fopen /home/USERNAME/.ssh/known_hosts2: No such file or directory debug1: load_hostkeys: fopen /etc/ssh/ssh_known_hosts: No such file or directory debug1: load_hostkeys: fopen /etc/ssh/ssh_known_hosts2: No such file or directory debug1: hostkeys_find_by_key_hostfile: hostkeys file /home/USERNAME/.ssh/known_hosts does not exist debug1: hostkeys_find_by_key_hostfile: hostkeys file /home/USERNAME/.ssh/known_hosts2 does not exist debug1: hostkeys_find_by_key_hostfile: hostkeys file /etc/ssh/ssh_known_hosts does not exist debug1: hostkeys_find_by_key_hostfile: hostkeys file /etc/ssh/ssh_known_hosts2 does not exist The authenticity of host 'localhost (127.0.0.1)' can't be established. ED25519 key fingerprint is SHA256:qwertzuiop123456789. This key is not known by any other names Are you sure you want to continue connecting (yes/no/[fingerprint])?
Wasn nun? Was läuft falsch? Oder was muss ich denn noch machen jetzt? yes, no, fingerprint?
Muss ich den Fingerprint (qwertzuiop123456789) nehmen der dort angegeben ist und den dann im Terminal dort eintragen damit die Verzeichnisse erstellt werden usw? Weil die ja laut Ausgabe nicht existieren (No such file or directory)
