Q) Au secours ! Les utilisateurs locaux ne peuvent pas se connecter.
A) There are various possible problems.
A1) By default, vsftpd disables any logins other than anonymous logins. Put
local_enable=YES in your /etc/vsftpd.conf to allow local users to log in.
A2) vsftpd tries to link with PAM. (Run "ldd vsftpd" and look for libpam to
find out whether this has happened or not). If vsftpd links with PAM, then
you will need to have a PAM file installed for the vsftpd service. There is
a sample one for RedHat systems included in the "RedHat" directory - put it
under /etc/pam.d
A3) If vsftpd didn't link with PAM, then there are various possible issues. Is
the user's shell in /etc/shells? If you have shadowed passwords, does your
system have a "shadow.h" file in the include path?
**A4) If you are not using PAM, then vsftpd will do its own check for a valid
user shell in /etc/shells. You may need to disable this if you use an invalid
shell to disable logins other than FTP logins. Put check_shell=NO in your
/etc/vsftpd.conf.**
Vous êtes le cas A4
Solution 2 :
Regardez check_shell dans man vsftpd.conf :
Note! This option only has an effect for non-PAM builds of vsftpd.
If disabled, vsftpd will not check /etc/shells for a valid user
shell for local logins.
Default: YES
Vous pouvez ajouter /usr/sbin/nologin à /etc/shells. Solution simple et facile.
Une autre consiste à modifier la configuration de vsftpd.conf/PAM.
Commentez cette ligne "auth ..." dans le cas PAM :
$ grep shells /etc/pam.d/vsftpd
auth required pam_shells.so
