NAME

6       nx_server_ssh_selinux   -   Security  Enhanced  Linux  Policy  for  the
7       nx_server_ssh processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the nx_server_ssh processes via  flexi‐
11       ble mandatory access control.
12
13       The  nx_server_ssh  processes  execute with the nx_server_ssh_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 nx_server_ssh_t
20
21
22

ENTRYPOINTS

24       The nx_server_ssh_t SELinux type can be entered via the ssh_exec_t file
25       type.
26
27       The default entrypoint paths for the  nx_server_ssh_t  domain  are  the
28       following:
29
30       /usr/bin/ssh
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       nx_server_ssh  policy  is  very  flexible allowing users to setup their
40       nx_server_ssh processes in as secure a method as possible.
41
42       The following process types are defined for nx_server_ssh:
43
44       nx_server_ssh_t
45
46       Note: semanage permissive -a nx_server_ssh_t can be used  to  make  the
47       process  type  nx_server_ssh_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       nx_server_ssh policy is extremely flexible  and  has  several  booleans
55       that  allow you to manipulate the policy and run nx_server_ssh with the
56       tightest access possible.
57
58
59
60       If you want to allow all domains to use other domains file descriptors,
61       you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63       setsebool -P allow_domain_fd_use 1
64
65
66
67       If  you  want  to allow confined applications to run with kerberos, you
68       must turn on the allow_kerberos boolean. Enabled by default.
69
70       setsebool -P allow_kerberos 1
71
72
73
74       If you want to allow sysadm to debug or ptrace all processes, you  must
75       turn on the allow_ptrace boolean. Disabled by default.
76
77       setsebool -P allow_ptrace 1
78
79
80
81       If  you  want  to  allow  system  to run with NIS, you must turn on the
82       allow_ypbind boolean. Disabled by default.
83
84       setsebool -P allow_ypbind 1
85
86
87
88       If you want to allow all domains to have the kernel load  modules,  you
89       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
90       default.
91
92       setsebool -P domain_kernel_load_modules 1
93
94
95
96       If you want to allow all domains to execute in fips_mode, you must turn
97       on the fips_mode boolean. Enabled by default.
98
99       setsebool -P fips_mode 1
100
101
102
103       If you want to enable reading of urandom for all domains, you must turn
104       on the global_ssp boolean. Disabled by default.
105
106       setsebool -P global_ssp 1
107
108
109
110       If you want to allow confined applications to use nscd  shared  memory,
111       you must turn on the nscd_use_shm boolean. Enabled by default.
112
113       setsebool -P nscd_use_shm 1

MANAGED FILES

118       The  SELinux process type nx_server_ssh_t can manage files labeled with
119       the following file types.  The paths listed are the default  paths  for
120       these  file  types.  Note the processes UID still need to have DAC per‐
121       missions.

171       mappings.
172

174       process type is permissive.
175
