沙箱里没有持久存储么？
那地址簿怎么保存的。
The host key is not cached for this server:
bbs.mysmth.net (port 22)
You have no guarantee that the server is the computer
you think it is.
The server's ecdsa-sha2-nistp256 key fingerprint is:
ecdsa-sha2-nistp256 256 SHA256:HsRMZnW4YqU3fOoYCcchTwK7b7Zqcbjap04O9OCtkG4
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n, Return cancels connection, i for more info)
