Par*_*_90 1 remote-access redhat-enterprise-linux
我是 Linux 操作系统的新手。我正在使用红帽 Linux。
谁能告诉我如何在不提供密码的情况下使用远程服务登录到远程机器?
Linux 中是否有任何命令,或者我必须为它编写“C”代码吗?
您不必编写代码。

其次,使用 ssh-copy-id 分发您的公钥
ssh-copy-id username@remote-machine

请注意,运行此命令时需要提供密码。之后,您无需密码即可登录远程机器。
以下是手册页中命令的一些解释:
ssh-keygen
ssh-keygen generates, manages and converts authentication keys for
ssh(1). ssh-keygen can create RSA keys for use by SSH protocol version 1
and DSA, ECDSA or RSA keys for use by SSH protocol version 2. The type
of key to be generated is specified with the -t option. If invoked with-
out any arguments, ssh-keygen will generate an RSA key for use in SSH
protocol 2 connections.

ssh-copy-id
ssh-copy-id is a script that uses ssh to log into a remote machine
and append the indicated identity file to that machine's
~/.ssh/authorized_keys file.
