You -can enable/disable access control using the \s-1XPA_ACL\s0 environment -variable. You can specify access to specific \s-1XPA\s0 access points for -specific machines using the \s-1XPA_DEFACL\s0 and \s-1XPA_ACLFILE\s0 environment -variables. By default, an \s-1XPA\s0 access point is accessible only to -processes running on the same machine (same as X Windows). -.SH "DESCRIPTION" -.IX Header "DESCRIPTION" -When \s-1INET\s0 sockets are in use (the default, as specified by the -\&\fI\s-1XPA_METHOD\s0\fR environment variable), \s-1XPA\s0 supports a host-based -access control mechanism for individual access points. This mean that -access can be specified for get, set, or info operations for each -access point on a machine by machine basis. For \s-1LOCAL\s0 sockets, access -is restricted (by definition) to the host machine. -.PP -\&\s-1XPA\s0 access control is enabled by default, but can be turned off by -setting the \fI\s-1XPA_ACL\s0\fR environment variable to \fIfalse\fR. -In this case, any process can access any \s-1XPA\s0 server. -.PP -Assuming that access control is turned on, the \s-1ACL\s0 for an individual -\&\s-1XPA\s0 access point is set up when that access point is registered -(although it can be changed later on; see below). This can be done in -one of two ways: -.PP -Firstly, the \fI\s-1XPA_ACLFILE\s0\fR environment variable can defined to -point to a file of access controls for individual access points. The format -of this file is: -.PP -.Vb 1 -\& class:name ip acl -.Ve -.PP -The first argument is a template that specifies the class:name of the -access point covered by this \s-1ACL\s0. See -\&\s-1XPA\s0 Access Points and Templates -for more information about xpa templates. -.PP -The second argument is the \s-1IP\s0 address (in human-readable format) of -the machine which is being given access. This argument can be -\&\fI*\fR to match all \s-1IP\s0 addresses. It also can be \fI\f(CI$host\fI\fR -to match the \s-1IP\s0 address of the current host. -.PP -The third argument is a string combination of \fIs\fR, \fIg\fR, -or \fIi\fR to allow \fIxpaset\fR, \fIxpaget\fR, or -\&\fIxpainfo\fR access respectively. The \s-1ACL\s0 argument can be -\&\fI+\fR to give \fIsgi\fR access or it can be \fI\-\fR to turn -off all access. -.PP -For example, -.PP -.Vb 3 -\& *:xpa1 somehost sg -\& *:xpa1 myhost + -\& * * g -.Ve -.PP -will allow processes on the machine somehost to make xpaget and xpaset calls, -allow processes on myhost to make any call, and allow all other hosts to -make xpaget (but not xpaset) calls. -.PP -Secondly, if the \fI\s-1XPA_ACLFILE\s0\fR does not exist, then a single -default value for all access points can be specified using the -\&\fI\s-1XPA_DEFACL\s0\fR environment variable. The default value for this -variable is: -.PP -.Vb 1 -\& #define XPA_DEFACL "*:* $host +" -.Ve -.PP -meaning that all access points are fully accessible to all processes -on the current host. Thus, in the absence of any \s-1ACL\s0 environment variables, -processes on the current host have full access to all access points -created on that host. This parallels the X11 xhost mechanism. -.PP -Access to an individual \s-1XPA\s0 access point can be changed using the \-acl -parameter for that access point. For example: -.PP -.Vb 1 -\& xpaset \-p xpa1 \-acl "somehost \-" -.Ve -.PP -will turn off all access control for somehost to the xpa1 access point, while: -.PP -.Vb 1 -\& xpaset \-p XPA:xpa1 \-acl "beberly gs" -.Ve -.PP -will give beberly xpaget and xpaset access to the access point whose -class is \s-1XPA\s0 and whose name is xpa1. -.PP -Similarly, the current \s-1ACL\s0 for a given access point can be retrieved using: -.PP -.Vb 1 -\& xpaget xpa1 \-acl -.Ve -.PP -Of course, you must have xpaget access to this \s-1XPA\s0 access point to -retrieve its \s-1ACL\s0. -.PP -Note that the \s-1XPA\s0 access points registered in the \fIxpans\fR -program also behave according to the \s-1ACL\s0 rules. That is, you cannot -use xpaget to view the access points registered with xpans unless -you have the proper \s-1ACL\s0. -.PP -Note also when a client request is made to an \s-1XPA\s0 server, the access -control is checked when the initial connection is established. This -access in effect at this time remains in effect so long as the client -connection is maintained, regardless of whether the access fro that -\&\s-1XPA\s0 is changed later on. -.PP -We recognize that host-based access control is only relatively secure -and will consider more stringent security (e.g., private key) in the -future if the community requires such support. -.SH "SEE ALSO" -.IX Header "SEE ALSO" -See xpa(n) for a list of \s-1XPA\s0 help pages |
