Po dokładniejszym sprawdzeniu informacje te można uzyskać na dwa sposoby.

  1. odczytu od strony man dla sshd_config(5)

    KexAlgorithms 
    Specifies the available KEX (Key Exchange) algorithms. 
    Multiple algorithms must be comma-separated. 
    The default is 
    ecdh-sha2-nistp256 , 
    ecdh-sha2-nistp384 , 
    ecdh-sha2-nistp521 , 
    diffie-hellman-group-exchange-sha256 , 
    diffie-hellman-group-exchange-sha1 , 
    diffie-hellman-group14-sha1 , 
    diffie-hellman-group1-sha1 . 
    
  2. odczytu z ssh -vvv dzienników (Pierwsza część jest kexalgorithm,hmac,ciphers obsługiwane po stronie klienta, a druga część to serwer sshd Użytkownika).

  3. zapytanie ssh o obsługiwane algorytmy: ssh -Q kex server (wielka litera -Q)

    diffie-hellman-group1-sha1 
    diffie-hellman-group14-sha1 
    diffie-hellman-group-exchange-sha1 
    diffie-hellman-group-exchange-sha256 
    ecdh-sha2-nistp256 
    ecdh-sha2-nistp384 
    ecdh-sha2-nistp521

myślę, że powinno być 'ssh-Q kex server' (górny przypadek 'P') – trvrm

' ssh-Q kex server' nie jest prawdziwa poleceń. 'ssh -Q kex' po prostu przeszukuje algorytmy klienta ssh. Nie ma żadnego serwera - argument jest po prostu ignorowany - spróbuj 'ssh -Q kex asdf'. – bain
