我可以使用JSCH将远程主机重新添加到known_host吗？ [英] can I re-add remote host to known_host using JSCH?

问题描述

我希望能够从known_hosts中删除远程服务器密钥并再次添加。远程服务器经常更新，因此我想自动删除远程主机密钥并将其新密钥添加到known_hosts。我可以从known_hosts中删除密钥，虽然它很笨重但使用 Process 而不是通过JSCH。这有效，但每当我尝试访问服务器时都会遇到此消息：

I want to be able to remove the remote server key from known_hosts and add it again. The remote server gets updated often so I want to automatically remove the remote host key and add its new key to known_hosts. I can remove the key from known_hosts though it is clunky and uses a Process instead of going through JSCH. This works but I encounter this message whenever I try to access the server:

The authenticity of host '192.168.1.1 (192.168.1.1)' can't be established.
RSA key fingerprint is 10:10:30:00:e7:0c:d3:18:cf:ac:42:e2:f3:51:25:bg.
Are you sure you want to continue connecting (yes/no)? 

我知道可以使用UserInfo解决此消息，但我使用其他方式连接到远程服务器，例如进程，当我运行这些命令时会出现消息。

I know it is possible to get around this message using a UserInfo but I use other ways of connecting to the remote server, such as a Process and the message would appear when I run those commands.

是否可能使用JSCH从known_hosts中删除和添加主机ID？

Is it possible to use JSCH to remove and add a host id from known_hosts?

虽然它不使用jsch但可能相关：

如何编写程序（脚本）以从〜/ .ssh / known_hosts中删除过时的主机密钥？

推荐答案

无需以编程方式操作 known_hosts

ssh -oStrictHostKeyChecking=no remote-host

或添加

StrictHostKeyChecking no

to 的〜/ .ssh / CONFI克。有关详细信息，请阅读 ssh_config（5）手册页。

to ~/.ssh/config. Read the ssh_config(5) man page for details.
