Error changing file permission over SFTP connection

[SkippiCZ]

Far Manager, version 3.0 (build 5100) x64 NetBox Version 2.4.5 (Build 531) (OS 10.0.16299 - Windows 10 Pro) Connection to SSH server on Red Hat Enterprise Linux 2.6.32-642.11.1.el6.x86_64 I tried to change permission of file "test.sh" - for example from "rwxr--r--" to "rw-r--r--", but FAR reported error:

╔═══════════════════ Error ════════════════════╗
║ Cannot change properties of file 'test.sh'.  ║

But I can see (on OS level and also after re-read directory in FAR), that permission of the file has changed. The same operation is working over FTP connection. Here you can see part of LOG file: . 2018-05-02 12:33:56.325 test.sh;-;189;2018-04-24T13:30:08.000Z;3;"pdsadm115" [512];"pdstage115" [512];rwxr--r--;0 . 2018-05-02 12:33:56.326 Startup conversation with host finished. . 2018-05-02 12:33:58.525 Detected network event . 2018-05-02 12:33:58.525 Received 13 bytes (0) . 2018-05-02 12:34:23.259 Changing properties of "test.sh" (No) . 2018-05-02 12:34:23.259 - mode: "u+rw-xs,g+r-wxs,o+r-wxt" . 2018-05-02 12:34:23.259 - group: "pdstage115" [0] . 2018-05-02 12:34:23.259 - owner: "pdsadm115" [0]

It seems, that NetBox is trying to change owner and group also and use incorrect id (0 instead of 512).

If I try to change also group (from 512=pdstage115 to 0=root) for file, WinSCP failed with the same error: Permission denied. Error code: 3 Error message from server: Permission denied

Access denied - see server settings.

As OP showed, the same works in WinSCP application. And I actually suffer from the same problem too, when I use your plugin. It's clearly a bug in the plugin.

Personally, I do not understand you - the phenomenon is reproduced and WinSCP - it is written in the log about the prohibition of access from the server, and in the NetBox, and because of your fault NetBox for WinSCP "by definition, there can be no errors," and "in NetBox sits an error ". Yes, there are errors introduced from WinSCP, but they are perfectly reproduced in it. Autumn after the "changes" in v5.10.3 Beta where WinSCP authors decided that the standards specifications should comply with everything, but only they did not break the work with the URL and FTP protocol.

[SkippiCZ]

Change of file permissions only (without change of group or owner) is working in WinSCP, but failed in NetBox. It seems that NetBox trying to change also group and owner, even when I did not changed it in properties.
