一、rsh的配置

1、安裝軟件、啟動服務

chkconfig rsh on

chkconfig rlogin on

service xinetd reload

創建/etc/hosts.equiv 文件

touch /etc/hosts.equiv

chmod 600 /etc/hosts.equiv

chown root:root /etc/hosts.equiv

編輯

+<hostname1>

+<hostname2>

二、ssh配置

1、配置ssh，生成密鑰

su - <user_name>

mkdir ~/.ssh

chmod 700 ~/.ssh

/usr/bin/ssh-keygen -t rsa # Accept the default settings.

exit

2、激活host1的user equivalency

Host1

su - <user_name>

cd ~/.ssh

cat id_rsa.pub >> authorized_keys

scp authorized_keys Host2:/<user_home_diretory>/.ssh/

exit

3、激活host2的user equivalency

Host2

su - <user_name>

cd ~/.ssh

cat id_rsa.pub >> authorized_keys

scp authorized_keys Host1:/<user_home_diretory>/.ssh/

兩臺主機都包含：authorized_keys

4、測試

su - <user_name>

ssh host1 date

ssh host2 date

ssh host1.localdomain date

ssh host2.localdomain date

exec /usr/bin/ssh-agent $SHELL

/usr/bin/ssh-add

exit
