SELinux is preventing /usr/sbin/sshd from 'read' accesses on the file /etc/localtime.

*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************

If you want to allow sftp-internal 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 'sftpd_full_access' boolean.
Do
setsebool -P sftpd_full_access 1

*****  Plugin catchall (11.6 confidence) suggests  ***************************

If you believe that sshd should be allowed read access on the localtime file 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 sshd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-07-14 16:06:44 UTC
Are you trying to get localtime file using sftpd?

Comment 2 Daniel Walsh 2011-07-14 17:34:32 UTC
Miroslav just add the following to RHEL6, F14, F15

miscfiles_read_localization(anon_sftpd_t)

miscfiles_read_localization(sftpd_t)

> Are you trying to get localtime file using sftpd?

Hi,
I am using the sftp internal to ssh, in sshd_config I set:
Subsystem sftp internal-sftp

the bug reported above shows up when I upload with sftp a file to the server

thanks
Luigi
