W sumie pobrałem Termux dla Androida 7.1, który będzie działał jako serwer zdalny.
C: klient (192.168.1.4), R: serwer zdalny (192.168.1.3)
- R: Na termuxie zainstalowałem openssh.
- C: ssh-keygen i wysyłanie id_rsa.pub
- R: odebrał plik i umieścił go w ~ / .ssh / authorized_keys
- R: sshd (aby uruchomić serwer ssh)
- C: ssh 192.168.1.3 -p 8022
Wydajność:
Connection to 192.168.1.3 closed by remote host.
Connection to 192.168.1.3 closed.
Teraz wyjście ssh -v 192.168.1.3 -p 8022
$ ssh -v 192.168.1.3 -p 8022
