Description gianluca 2011-10-25 07:03:04 UTC
SELinux is preventing /usr/sbin/vsftpd from 'write' accesses on the directory /home/gianluca.

*****  Plugin catchall_boolean (47.5 confidence) suggests  *******************

If you want to allow ftp servers to login to local users and read/write all files on the system, governed by DAC.
Then you must tell SELinux about this by enabling the 'allow_ftpd_full_access' boolean.
Do
setsebool -P allow_ftpd_full_access 1

*****  Plugin catchall_boolean (47.5 confidence) suggests  *******************

If you want to allow ftp to read and write files in the user home directories
Then you must tell SELinux about this by enabling the 'ftp_home_dir' boolean.
Do
setsebool -P ftp_home_dir 1

*****  Plugin catchall (6.38 confidence) suggests  ***************************

If you believe that vsftpd should be allowed write access on the gianluca directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep vsftpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

If you want to allow to share your home then you need to turn on the ftp_home_dir boolean.

# setsebool -P ftp_home_dir 1
