NAME

       nx_server_ssh_selinux - Security Enhanced Linux Policy for the nx_server_ssh processes

DESCRIPTION

       Security-Enhanced Linux secures the nx_server_ssh processes via flexible mandatory access control.

       The  nx_server_ssh  processes execute with the nx_server_ssh_t SELinux type. You can check if you have these processes running by executing
       the ps command with the -Z qualifier.

       For example:

       ps -eZ | grep nx_server_ssh_t

ENTRYPOINTS

       The nx_server_ssh_t SELinux type can be entered via the ssh_exec_t file type.

       The default entrypoint paths for the nx_server_ssh_t domain are the following:

       /usr/bin/ssh, /usr/libexec/nm-ssh-service

PROCESS TYPES

       SELinux defines process types (domains) for each process running on the system

       You can see the context of a process using the -Z option to ps

       Policy governs the access confined processes have to files.  SELinux nx_server_ssh policy is very flexible allowing users  to  setup  their
       nx_server_ssh processes in as secure a method as possible.

       The following process types are defined for nx_server_ssh:

       nx_server_ssh_t

       Note:  semanage permissive -a nx_server_ssh_t can be used to make the process type nx_server_ssh_t permissive. SELinux does not deny access
       to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS

       SELinux policy is customizable based on least access required.  nx_server_ssh policy is extremely flexible and has  several  booleans  that
       allow you to manipulate the policy and run nx_server_ssh with the tightest access possible.

       If  you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlo-
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to deny any process from ptracing or debugging any other processes, you must  turn  on  the	deny_ptrace  boolean.  Enabled	by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want  to  allow  all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by
       default.

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

       setsebool -P fips_mode 1

       If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 1

       If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 1

       If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

       setsebool -P nscd_use_shm 1

NSSWITCH DOMAIN

       If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the  nx_server_ssh_t,  you
       must turn on the authlogin_nsswitch_use_ldap boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the nx_server_ssh_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES

       The  SELinux  process  type nx_server_ssh_t can manage files labeled with the following file types.  The paths listed are the default paths
       for these file types.  Note the processes UID still need to have DAC permissions.

       ssh_home_t

	    /var/lib/[^/]+/.ssh(/.*)?
	    /root/.ssh(/.*)?
	    /var/lib/one/.ssh(/.*)?
	    /var/lib/pgsql/.ssh(/.*)?
	    /var/lib/openshift/[^/]+/.ssh(/.*)?
	    /var/lib/amanda/.ssh(/.*)?
	    /var/lib/stickshift/[^/]+/.ssh(/.*)?
	    /var/lib/gitolite/.ssh(/.*)?
	    /var/lib/nocpulse/.ssh(/.*)?
	    /var/lib/gitolite3/.ssh(/.*)?
	    /var/lib/openshift/gear/[^/]+/.ssh(/.*)?
	    /root/.shosts
	    /home/[^/]*/.ssh(/.*)?
	    /home/[^/]*/.ansible/cp/.*
	    /home/[^/]*/.shosts

       user_tmp_t

	    /var/run/user(/.*)?
	    /tmp/hsperfdata_root
	    /var/tmp/hsperfdata_root
	    /tmp/gconfd-.*

COMMANDS

       semanage fcontext can also be used to manipulate default file context mappings.

       semanage permissive can also be used to manipulate whether or not a process type is permissive.

       semanage module can also be used to enable/disable/install/remove policy modules.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
