mtime.sec is not present
提问by user2190101
I am facing a tricky situation here. I have a java based application that tries to scp remote machines to copy certain files. While performing those tasks , I am finding the below error message from the application side.
我在这里面临一个棘手的情况。我有一个基于 java 的应用程序，它尝试 scp 远程机器来复制某些文件。在执行这些任务时，我从应用程序端发现以下错误消息。
scp protocol error mtime.sec not present
But when I manually try to scp from the server to endpoint machine, I am able to do it without issues.
但是当我手动尝试从服务器到端点机器的 scp 时，我能够毫无问题地做到这一点。
The command I am using for manual testing is scp localfile user@hostname:/tmp/
我用于手动测试的命令是 scp localfile user@hostname:/tmp/
I am not sure of the error message mtime.sec is not present. Does anyone can throw some lights here. I couldn't find useful info from web, Any experts thoughts would help a lot.
我不确定错误信息mtime.sec is not present。有没有人可以在这里扔一些灯。我无法从网上找到有用的信息，任何专家的想法都会有很大帮助。
As SCP is working normally using manual process, I am not sure there is something wrong with SCP.
由于 SCP 使用手动流程正常工作，我不确定 SCP 是否有问题。

I've got the same issue. It worked for me if I scp to ubuntu 12.04. When I did that to ubuntu 14.04, it failed with same message.
我有同样的问题。如果我 scp 到 ubuntu 12.04，它对我有用。当我对 ubuntu 14.04 执行此操作时，它失败并显示相同的消息。
I wrote the scp code based on this example http://www.jcraft.com/jsch/examples/ScpTo.java.html. I guess you too.
我根据这个例子编写了 scp 代码http://www.jcraft.com/jsch/examples/ScpTo.java.html。我猜你也是。
If I remove the whitespace after the "T" in the following line, it'll work. Change:
如果我删除下一行中“T”后面的空格，它将起作用。改变：
command="T "+(_lfile...
to
到
command="T"+(_lfile...
Either do that or set ptimestamp = false
要么这样做，要么设置 ptimestamp = false

protocol error: mtime.sec not delimited
I Googled this and learnt that this is a convoluted error message. We recently disabled our root login by making it 'nologin'. I forgot to update my scp script which was still trying to login as root. When I updated it use the new login all was fine. (sorry nothing to do with Java)
我用谷歌搜索了一下，发现这是一个复杂的错误信息。我们最近通过将其设置为“nologin”来禁用我们的 root 登录。我忘了更新我的 scp 脚本，它仍然试图以 root 身份登录。当我更新它时，使用新的登录名一切都很好。（抱歉与Java无关）

Like ZZapper above writes.
就像上面的 ZZapper 所写。
I ran into the same issue as above, trying to use scp to connect to a remote site and it also told me "protocol error: mtime.sec not delimited "
我遇到了与上面相同的问题，尝试使用 scp 连接到远程站点，它还告诉我“协议错误：mtime.sec 未分隔”
Running scp with -vvvvit turned out on the 'server side' they disallowed me to use scp and told me to use sftp instead.
scp with -vvvv结果是在“服务器端”运行它，他们不允许我使用 scp 并告诉我改用 sftp。

I learned my issue derived from the fact that our stftp server solely allows sftp connections. scp is not allowed.
我了解到我的问题源于我们的 stftp 服务器只允许 sftp 连接这一事实。scp 是不允许的。

Sink: This service allows sftp connections only.
