|
|
.SH "NAME"
|
|
samba_selinux \- Security Enhanced Linux Policy for Samba
|
|
.SH "DESCRIPTION"
|
|
|
|
Security-Enhanced Linux secures the Samba server via flexible mandatory access
|
|
control.
|
|
.SH FILE_CONTEXTS
|
|
SELinux requires files to have an extended attribute to define the file type.
|
|
Policy governs the access daemons have to these files.
|
|
If you want to share files other than home directories, those files must be
|
|
labeled samba_share_t. So if you created a special directory /var/eng, you
|
|
would need to label the directory with the chcon tool.
|
|
.TP
|
|
chcon -t samba_share_t /var/eng
|
|
.TP
|
|
If you want to make this permanant, i.e. survive a relabel, you must add an entry to the file_contexts.local file.
|
|
.TP
|
|
/etc/selinux/POLICYTYPE/contexts/files/file_contexts.local
|
|
.br
|
|
/var/eng(/.*)? system_u:object_r:samba_share_t
|
|
|
|
.SH SHARING FILES
|
|
If you want to share files with multiple domains (Apache, FTP, rsync, Samba), you can set a file context of public_content_t and public_content_rw_t. These context allow any of the above domains to read the content. If you want a particular domain to write to the public_content_rw_t domain, you must set the appropriate boolean. allow_DOMAIN_anon_write. So for samba you would execute:
|
|
|
|
setsebool -P allow_smbd_anon_write=1
|
|
|
|
.SH BOOLEANS
|
|
.br
|
|
SELinux policy is customizable based on least access required. So by
|
|
default SElinux policy turns off SELinux sharing of home directories and
|
|
the use of Samba shares from a remote machine as a home directory.
|
|
.TP
|
|
If you are setting up this machine as a Samba server and wish to share the home directories, you need to set the samba_enable_home_dirs boolean.
|
|
.br
|
|
|
|
setsebool -P samba_enable_home_dirs 1
|
|
.TP
|
|
If you want to use a remote Samba server for the home directories on this machine, you must set the use_samba_home_dirs boolean.
|
|
.br
|
|
|
|
setsebool -P use_samba_home_dirs 1
|
|
.TP
|
|
system-config-selinux is a GUI tool available to customize SELinux policy settings.
