![Openssl:无法下载更改端口的证书](https://linux22.com/image/91603/Openssl%EF%BC%9A%E6%97%A0%E6%B3%95%E4%B8%8B%E8%BD%BD%E6%9B%B4%E6%94%B9%E7%AB%AF%E5%8F%A3%E7%9A%84%E8%AF%81%E4%B9%A6.png)
我使用以下命令从服务器下载 FTPS 证书:
echo | openssl s_client -showcerts -connect 192.168.1.88:990
证书按预期下载。
现在,在服务器端,如果我将默认端口更改990
为某个未使用的端口100
,并再次对新端口使用与上面相同的命令,则会发生错误。
echo | openssl s_client -showcerts -connect 192.168.1.88:100
错误说:
CONNECTED(00000003)

当默认端口更改时,如何从服务器下载 FTPS 证书?
(虽然,我问的是 FTPS,但仅 HTTPS 也存在同样的问题。但现在我只关心 FTPS)
