ubuntu - openSSL漏洞，在线升级会影响SSH登录么？

昨天爆出的 heartbleed 要求把openSSL升级到 1.0.1g版本。

我查了一些资料，准备着手进行升级，但我担心升级会影响SSH登录。

我的VPS是Ubuntu 12.04，通过远程登录SSH管理。

请问，通过SSH远程登录升级OpenSSL，会影响到当前或者以后的SSH远程登录么？

    To be safe, you enter the command to upgrade openssl on the existing ssh connection, and then restart the service. Don't disconnect from SSH. Then open a new SSH session and confirm that everything is normal before disconnecting the old SSH connection.

    Choose a quiet time at night to upgrade. First simulate it several times in the experimental environment.

    Ssh is theoretically influential
    But this is only for statically compiled ssh
    Generally, ssh is compiled dynamically
    Just upgrade openssl

    Log in to the VPS with SSH and upgrade directly with apt-get update and apt-get upgrade.

    After the upgrade, although OpenSSL is still 1.0.1e, the BUG has been fixed.

    Theoretically there will be no problems. In order to prevent problems, it is recommended to open a new SSH and try to log in successfully before disconnecting the existing SSH
