6 nx_server_ssh_selinux - Security Enhanced Linux Policy for the
7 nx_server_ssh processes
8
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
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, /usr/libexec/nm-ssh-service
31
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.
50
51
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.

59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Enabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type nx_server_ssh_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.

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.
