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 determine whether screen can use fsetid/setuid/setgid
68       capability, you must turn on the screen_allow_session_sharing  boolean.
69       Disabled by default.
70
71       setsebool -P screen_allow_session_sharing 1
72
73
74
75       If  you  want  to  support  NFS  home directories, you must turn on the
76       use_nfs_home_dirs boolean. Disabled by default.
77
78       setsebool -P use_nfs_home_dirs 1
79
80
81
82       If you want to support SAMBA home directories, you  must  turn  on  the
83       use_samba_home_dirs boolean. Disabled by default.
84
85       setsebool -P use_samba_home_dirs 1

MANAGED FILES

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

95       faillog_t
96
97            /var/log/btmp.*

COMMANDS

129       semanage fcontext can also be used to manipulate default  file  context
130       mappings.
131
132       semanage  permissive  can  also  be used to manipulate whether or not a
133       process type is permissive.
134
135       semanage module can also be used to enable/disable/install/remove  pol‐
136       icy modules.
137
138       semanage boolean can also be used to manipulate the booleans
139
140
141       system-config-selinux is a GUI tool available to customize SELinux pol‐
142       icy settings.
