有谁知道我怎么能通过ssh_port ssh-copy-id来启用密码减less远程SSHlogin..
ssh-copy-id只是一个shell脚本，所以你可以把“-p”放在“ ssh $1 ”行的脚本中，改成“ ssh -p <alternateport> $1 ”
我build议将系统复制到您的主目录并修改，而不是直接修改已安装的目录。
这是修改的例子，在脚本的顶部使用一个variables（名为SSH），您可以轻松修改以添加所需的任何ssh选项。 在你的情况下，用你感兴趣的端口replacePORTNUM：
#!/bin/sh # Shell script to install your public key on a remote machine # Takes the remote machine name as an argument. # Obviously, the remote machine must accept password authentication, # or one of the other keys in your ssh-agent, for this to work. ID_FILE="${HOME}/.ssh/id_rsa.pub" SSH="/usr/bin/ssh -p PORTNUM" if [ "-i" = "$1" ]; then shift # check if we have 2 parameters left, if so the first is the new ID file if [ -n "$2" ]; then if expr "$1" : ".*\.pub" > /dev/null ; then ID_FILE="$1" else ID_FILE="$1.pub" fi shift # and this should leave $1 as the target name fi else if [ x$SSH_AUTH_SOCK != x ] ; then GET_ID="$GET_ID ssh-add -L" fi fi if [ -z "`eval $GET_ID`" ] && [ -r "${ID_FILE}" ] ; then GET_ID="cat ${ID_FILE}" fi if [ -z "`eval $GET_ID`" ]; then echo "$0: ERROR: No identities found" >&2 exit 1 fi if [ "$#" -lt 1 ] || [ "$1" = "-h" ] || [ "$1" = "--help" ]; then echo "Usage: $0 [-i [identity_file]] [user@]machine" >&2 exit 1 fi { eval "$GET_ID" ; } | ${SSH} $1 "umask 077; test -d .ssh || mkdir .ssh ; cat >> .ssh/authorized_keys; test -x /sbin/restorecon && /sbin/restorecon .ssh .ssh/authorized_keys" || exit 1 cat <<EOF Now try logging into the machine, with "ssh '$1'", and check in: .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting. EOF
为ssh创build一个configuration文件，它必须是〜/ .ssh / config，并将以下行添加到文件中。
Host <name> HostName <the host to connect to> Port <the_port_number> User <your user_name>
如果你然后做一个“ssh-copy-id -i …”它将工作。
我发现你也可以像这样将ssh命令传递给原始脚本：
ssh-copy-id -i .ssh/id_dsa.pub "[email protected] -p 1234"
所以你引用传递给ssh的部分作为主机url，并且ssh程序select了port参数。
