.TH NEWROLE "1" "October 2000" "Security Enhanced Linux" NSA
|
|
.SH NAME
|
|
newrole \- run a shell with a new SELinux role
|
|
.SH SYNOPSIS
|
|
.B newrole
|
|
[\fB-r\fR|\fB--role\fR]
|
|
\fIROLE\fR
|
|
[\fB-t\fR|\fB--type\fR]
|
|
\fITYPE\fR
|
|
[\fB-l\fR|\fB--level\fR]
|
|
\fILEVEL\fR [-- [\fIARGS\fR]...]
|
|
.SH DESCRIPTION
|
|
.PP
|
|
Run a new shell in a new context. The new context is derived from the
|
|
old context in which
|
|
.B newrole
|
|
is originally executed. If the
|
|
.B -r
|
|
or
|
|
.B --role
|
|
option is specified, then the new context will have the role specified by
|
|
\fIROLE\fR.
|
|
If the
|
|
.B -t
|
|
or
|
|
.B --type
|
|
option is specified, then the new context will have the type (domain)
|
|
specified by
|
|
\fITYPE\fR.
|
|
If a role is specified, but no type is specified, the default type is derived
|
|
from the specified role. If the
|
|
.B -l
|
|
or
|
|
.B --level
|
|
option is specified, then the new context will have the sensitivity level
|
|
specified by
|
|
\fILEVEL\fR.
|
|
If
|
|
\fILEVEL\fR
|
|
is a range, the new context will have the sensitivity level and clearance
|
|
specified by that range.
|
|
.PP
|
|
Additional arguments
|
|
.I ARGS
|
|
may be provided after a -- option,
|
|
in which case they are supplied to the new shell.
|
|
In particular, an argument of -- -c will cause the next argument to be
|
|
treated as a command by most command interpreters.
|
|
.PP
|
|
If a command argument is specified to newrole and the command name is found
|
|
in /etc/selinux/newrole_pam.conf, then the pam service name listed in that
|
|
file for the command will be used rather than the normal newrole pam
|
|
configuration. This allows for per-command pam configuration when
|
|
invoked via newrole, e.g. to skip the interactive re-authentication phase.
|
|
.PP
|
|
The new shell will be the shell specified in the user's entry in the
|
|
.I /etc/passwd
|
|
file.
|
|
.PP
|
|
The
|
|
.B -V
|
|
or
|
|
.B --version
|
|
shows the current version of newrole
|
|
.PP
|
