Salut,
Tiens jettes un oeil à cette FAQ :
http://www.vsftpdrocks.org/faq/
Surtout ce passage :
Q) Help! Uploaded files are appearing with permissions -rw-------.
A1) Depending on if this is an upload by a local user or an anonymous user,
use "local_umask" or "anon_umask" to change this. For example, use
"anon_umask=022" to give anonymously uploaded files permissions
-rw-r--r--. Note that the "0" before the "22" is important.
A2) Also see the vsftpd.conf.5 man page for the new "file_open_mode"
parameter.
La page de man :
http://vsftpd.beasts.org/vsftpd_conf.html
et la section concernée :
file_open_mode
The permissions with which uploaded files are created. Umasks are applied on top of this value. You may wish to change to 0777 if you want uploaded files to be executable.
Default: 0666
