给出lftp
类似于以下内容的命令:
lftp -vv -d -c set ssl:ca-file /path/to/cert/ftps_cron-bundle.crt; set ssl:check-hostname no; set ftp:ssl-protect-data true; set sftp:connect-program "ssh -a -x -o PubkeyAuthentication=no"; set net:max-retries 2; open -e 'put /path/to/data/upload.txt;' -u username:password ftps://server.example.net/
该命令模板适用于各种服务器,但在一台服务器上,即使上传成功,也会显示错误消息:
---- CWD path to be sent is `/'
<--- 200 Command OPTS succeed
---> CWD /
<--- 550 Permission denied
cd: Access failed: 550 Permission denied (/)
如何阻止lftp
发送CWD /
到该服务器?
<--- 230 User logged in

---> LANG
<--- 200 Default languages set to EN
---> OPTS UTF8 ON
<--- 200 Command OPTS succeed
---> OPTS MLST size;type;perm;modify;
---- CWD path to be sent is `/'
请注意,服务器会根据用户名自动设置其默认上传目录……即/username/folder
上传应该会转到此默认上传目录,而不会生成错误消息。它确实上传了,但日志显示了错误消息:
cd: Access failed: 550 Permission denied (/)
---> TYPE I
<--- 200 Transfer mode set to BINARY
---> PASV
<--- 227 Entering Passive Mode (10,10,35,21,195,225).
---- Address returned by PASV seemed to be incorrect and has been fixed

<--- 200 Command ALLO succeed

<--- 226 Transfer completed

<--- 550 Command SITE failed

尝试了很多方法。例如,使用 put 命令的各种路径。
put -O . /path/to/data/upload.txt
put -O /username/folder /path/to/data/upload.txt
cd /username/folder
还尝试明确地发出命令。
删除-vv
和-d
也是无效的。
如何才能lftp
避免自动发出CWD /
不必要的、令人困惑的错误消息,而该消息实际上并不意味着任何事情都失败了?

在 URL 末尾附加波浪符号 (~):
ftps://server.example.net/~
或者,直接删除结尾的斜杠:
ftps://server.example.net
