Ubuntu中让SSH自动重连，简单的办法是安装autossh和expect。autossh负责自动重连，expect负责自动输入密码。
安装：
sudo apt
-
get install autossh
sudo apt - get install expect
sudo apt - get install expect
新建一个sh脚本，例如：/etc/autossh.sh，内容：
#
!/bin/bash
HOST = " xx.xxx.com "
USER = "yourname "
PASS = "yourpassword "
CMD = $@
VAR = $(expect - c "
spawn / usr / bin / autossh - M 2000 - N - v - D 127.0 . 0.1 : 7070 $USER@$HOST $CMD
match_max 100000
expect \ " *?assword:*\ "
send -- \ " $PASS\r\ "
send -- \ " \r\ "
expect eof
" )
echo " =============== "
echo " $VAR "
HOST = " xx.xxx.com "
USER = "yourname "
PASS = "yourpassword "
CMD = $@
VAR = $(expect - c "
spawn / usr / bin / autossh - M 2000 - N - v - D 127.0 . 0.1 : 7070 $USER@$HOST $CMD
match_max 100000
expect \ " *?assword:*\ "
send -- \ " $PASS\r\ "
send -- \ " \r\ "
expect eof
" )
echo " =============== "
echo " $VAR "
运行/etc/autossh.sh，就自动登录了
