NAME

6       sysadm_screen_selinux   -   Security  Enhanced  Linux  Policy  for  the
7       sysadm_screen processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the sysadm_screen processes via  flexi‐
11       ble mandatory access control.
12
13       The  sysadm_screen  processes  execute with the sysadm_screen_t SELinux
14       type. You can check if you have these processes  running  by  executing
15       the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep sysadm_screen_t

22

ENTRYPOINTS

24       The  sysadm_screen_t  SELinux type can be entered via the screen_exec_t
25       file type.
26
27       The default entrypoint paths for the  sysadm_screen_t  domain  are  the
28       following:
29
30       /usr/bin/tmux, /usr/bin/screen
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       sysadm_screen  policy  is  very  flexible allowing users to setup their
40       sysadm_screen processes in as secure a method as possible.
41
42       The following process types are defined for sysadm_screen:
43
44       sysadm_screen_t
45
46       Note: semanage permissive -a sysadm_screen_t can be used  to  make  the
47       process  type  sysadm_screen_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.

51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       sysadm_screen policy is extremely flexible  and  has  several  booleans
55       that  allow you to manipulate the policy and run sysadm_screen with the
56       tightest access possible.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1
64
65
66
67       If  you  want  to  allow  system  to run with NIS, you must turn on the
68       nis_enabled boolean. Disabled by default.
69
70       setsebool -P nis_enabled 1
71
72
73
74       If you want to determine whether screen  can  use  fsetid/setuid/setgid
75       capability,  you must turn on the screen_allow_session_sharing boolean.
76       Disabled by default.
77
78       setsebool -P screen_allow_session_sharing 1
79
80
81
82       If you want to support NFS home  directories,  you  must  turn  on  the
83       use_nfs_home_dirs boolean. Disabled by default.
84
85       setsebool -P use_nfs_home_dirs 1
86
87
88
89       If  you  want  to  support SAMBA home directories, you must turn on the
90       use_samba_home_dirs boolean. Disabled by default.
91
92       setsebool -P use_samba_home_dirs 1

MANAGED FILES

97       The SELinux process type sysadm_screen_t can manage files labeled  with
98       the  following  file types.  The paths listed are the default paths for
99       these file types.  Note the processes UID still need to have  DAC  per‐
100       missions.

103
104            /var/log/btmp.*

COMMANDS

136       semanage  fcontext  can also be used to manipulate default file context
137       mappings.
138
139       semanage permissive can also be used to manipulate  whether  or  not  a
140       process type is permissive.
141
142       semanage  module can also be used to enable/disable/install/remove pol‐
143       icy modules.
144
145       semanage boolean can also be used to manipulate the booleans
146
147
148       system-config-selinux is a GUI tool available to customize SELinux pol‐
149       icy settings.
