Title:
Can't replace exist file by mod-sftp
Status in “proftpd-dfsg” package in Ubuntu:
New
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.
