SSH Linux 伺服器無法正確執行所有命令

Question

我透過 SSH + 密碼使用 Putty 連接到我的網頁伺服器，並希望產生一對金鑰來為我登入。不幸的是，該命令不知何故“卡住”了..正如您在螢幕截圖

為什麼會發生這種情況？

Answer 1

看起來您首先連接到遠端伺服器，然後產生密鑰。不要那樣做！您的私鑰永遠不應該離開您的本機系統。您應該使用以下命令在本機產生金鑰：普蒂根，然後將產生的公鑰放入authorized_keys遠端主機上的檔案中。

Answer 2

這是我用來產生 SSH 金鑰的腳本。試一試。

#!/bin/sh

KEY="$HOME/.ssh/id_dsa.pub"

if [ ! -f ~/.ssh/id_dsa.pub ];then
  ssh-keygen -t dsa -b 1024 -f ~/.ssh/id_dsa -N ''
fi

if [ -z $1 ];then
    echo " "
    echo "Usage: $0 {[email protected]}"
    echo "  "
    echo "  The 'user' is the remote user account allowed to authenticate to"
    echo "  the 'remote.host'."
    echo "  "
    echo "  This ssh connection is used once to copy your key to the 'remote.host'"
    echo "  "
    exit
fi

echo "Sending your key to $1... "

KEYCODE=`cat $KEY`
ssh -q $1 "mkdir ~/.ssh 2>/dev/null; chmod 700 ~/.ssh; echo "$KEYCODE" >> ~/.ssh/authorized_keys; chmod 644 ~/.ssh/authorized_keys"

echo "done!"
