Настройка клиента:
- Для включение защиты по пин-коду необходимо установить пакет ssh-askpass. Для этого необходимо открыть терминал и выполнить команду:
Code Block language bash $ sudo apt-get install
...
ssh-askpass- Укажем ssh-agent что необходимо запрашивать пин-код. Выполним команду
Настройка клиента:
- открываем терминал и создаем папку для ключей:
Code Block language bash $ mkdir ~/.ssh eval "$(ssh-agent -s; SSH_ASKPASS=/usr/bin/ssh-askpass)"
- Генерируем ключи:
Code Block language bash $ cd ~/.ssh $ sh-keygen -t ecdsa-sk -O resident -O application=ssh:YourTextHere -O verify-required Generating public/private ecdsa-sk key pair. You may need to touch your authenticator to authorize key generation. Enter PIN for authenticator: Enter file in which to save the key (/home/tester/.ssh/id_ecdsa_sk): /home/tester/.ssh/id_ecdsa_sk already exists. Overwrite (y/n)? y Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/tester/.ssh/id_ecdsa_sk Your public key has been saved in /home/tester/.ssh/id_ecdsa_sk.pub The key fingerprint is: SHA256:veX8eVHMp6r5jmrCtyonIK/bymj/22cyB8KytayhCz0 tester@192.168.88.141vIIfHBajgeOHYoMjbzaE2eUoXU40jwSALfpuHjr9YA tester@tester2310 The key's randomart image is: +-[ECDSA-SK 256]--+ | +.o+ . | | .ooO . | | o o= * | | . =| | .
