[Bug 1296488] Re: Can't replace exist file by mod-sftp

[sense]

Thanks TJ Saunders, follow is his reply:

Here's your culprit here.  By default, proftpd does not allow overwriting
of existing files (this includes appending to existing files); see:

http://www.proftpd.org/docs/directives/linked/config_ref_AllowOverwrite.html


This means that adding e.g.:

  <Global>
    AllowOverwrite on
  </Global>

to your proftpd.conf should help.

And it's works.

Title:
  Can't replace exist file by mod-sftp

Status in “proftpd-dfsg” package in Ubuntu:
  Invalid

Bug description:
  Ubuntu version: 12.04.4
  proftpd-basic 1.3.4a-1 (with mod_sftp 0.9.8)
  sftp client: openssh-client 1:5.9p1-5ubuntu1.1

  I separately test replace file in ftp and sftp(ssh) both  same Proftpd
  server and the same user(not root). The test by ftp, it can replace
  the file no problem. But the test by sftp keep say:

  remote open("/test.txt"): Permission denied

  But when I remove test.txt first and upload the locally test.txt by
  sftp, it will be ok. So it's not the user's right or file path
  problem.

  Follow is the configure file
