#Linux技巧 阻止ssh自动断开（重发）

cd /etc/ssh

grep ClientAlive sshd_config

cp sshd_config sshd_config.bak
sed -i "s/#ClientAliveInterval 0/ClientAliveInterval 60/g" sshd_config

sed -i "s/#ClientAliveCountMax 3/ClientAliveCountMax 3/g" sshd_config

grep ClientAlive sshd_config

diff sshd_config sshd_config.bak

service sshd reload

再补上一条@literalkernel：

sed -i '/^PasswordAuthentication/c PasswordAuthentication yes' ${SSHD_CONFIG}
