The +default is 100. +.PP +.SH DESCRIPTION +The X firewall proxy (xfwp) is an application layer gateway proxy +that may be run on a network firewall host to forward X traffic +across the firewall. Used in conjunction with the X server Security +extension and authorization checking, xfwp constitutes a safe, simple, +and reliable mechanism both to hide the addresses of X servers located +on the Intranet and to enforce a server connection policy. Xfwp cannot +protect against mischief originating on the Intranet; however, when +properly configured it can guarantee that only trusted clients originating +on authorized external Internet hosts will be allowed inbound access to +local X servers. + +To use xfwp there must be an X proxy manager running in the local environment +which has been configured at start-up to know the location of the xfwp. +[NOTE: There may be more than one xfwp running in a local environment; +see notes below on load balancing for further discussion.] Using the +xfindproxy utility (which relays its requests through the proxy manager) +a user asks xfwp to allocate a client listen port for a particular X server, +which is internally associated with all future connection requests for that +server. This client listen port address is returned by the proxy manager +through xfindproxy. The xfwp hostname and port number is then passed +out-of-band (i.e., via a Web browser) to some remote X client, which will +subsequently connect to xfwp instead of to the target X server. + +When an X client connection request appears on one of xfwp's listen ports, +xfwp connects to the X server associated with this listen port and performs +authorization checks against the server as well as against its own configurable +access control list for requesting clients. If these checks fail, or if +the requested server does not support the X Security Extension, the client +connection is refused. Otherwise, the connection is accepted and all ensuing +data between client and server is relayed by xfwp until the client terminates +the connection or, in the case of an inactive client, until a configured +timeout period is exceeded. Xfwp is designed to block while waiting for +activity on its connections, thereby minimizing demand for system cycles. + +If xfwp is run without a configuration file and thus no sitepolicy is +defined, if xfwp is using an X server where xhost + has been run to turn +off host-based authorization checks, when a client tries to connect to +this X server via xfwp, the X server will deny the connection. If xfwp +does not define a sitepolicy, host-based authorization must be turned on +for clients to connect to an X server via the xfwp. +.PP +.SH INTEROPERATION WITH IP PACKET-FILTERING ROUTERS +The whole purpose of the xfwp is to provide reliable control over access +to Intranet X servers by clients originating outside the firewall. At +the present time, such access control is typically achieved by firewall +configurations incorporating IP packet-filtering routers. Frequently, +the rules for such filters deny access to X server ports (range 6000 - +6xxx) for all Intranet host machines. + +In order for xfwp to do its job, restrictions on access for ports 6001 - 6xxx +must be removed from the rule-base of the IP packet-filtering router. [NOTE: +xfwp only assigns ports in the range beginning with 6001; access to port +6000 on all Intranet hosts may continue to be denied.] This does not +mean the Intranet firewall will be opened for indiscriminate entry by X +clients. Instead, xfwp supports a fully configurable rule-based access +control system, similar to that of the IP packet-filter router itself. +Xfwp in effect adds another level of packet-filtering control which is +fully configurable and applies specifically to X traffic. See section +entitled CONFIGURATION FILE, below, for further details. +.PP +.SH INSTALLATION, SETUP AND TROUBLESHOOTING +Xfwp is typically run as a background process on the Intranet firewall host. +It can be launched using any of the command-line options described above. +As noted above, xfwp works only in conjunction with proxy manager and the +xfindproxy utility. It can also be configured to support a user-defined +X server site security policy, in which the X server is required to indicate +to xfwp whether or not it supports the particular policy. Consult the +X server man pages for further information on these components. Xfwp +diagnostics can be turned on by compiling with the -DDEBUG switch. +Connection status can be recorded by using the -logfile and -loglevel +command line options. +.PP +.SH PERFORMANCE, LOAD BALANCING AND RESOURCE MANAGEMENT +Xfwp manages four different kinds of connections: proxy manager (PM) data, +X client listen, X client data, and X server. The sysadmin employing xfwp +must understand how the resources for each of these connection types are +allocated and reclaimed by xfwp in order to optimize the availability of +xfwp service. + +Each connection-type has a default number of allocation slots and +a default timeout. The number of allocation slots for PM connections +and X server connections is configurable via command line options. +Connection timeouts are also configurable via command line options. +Each connection timeout represents the period the connection +will be allowed to remain open in the absence of any activity on that +connection. Whenever there is activity on a connection, the time-to-close +is automatically reset. The default distribution of total process connection +slots across the four connection types, as well as the choice of default +timeouts for the connection types, is governed by a number of assumptions +embedded in the xfwp use model. + + +The default number of PM connections is 10 and the +default duration for PM connections is 3,600 +seconds (1 hour) for each connection after time of last activity. +At start-up, xfwp listens for PM connection requests on any non-reserved +port (default of 4444 if not specified on the xfwp command-line). The PM +normally connects to xfwp only when a call is made to the PM with xfindproxy. +Thereafter, the PM remains connected to xfwp, even after the messaging between +them has been completed, for the default connection duration period. In some +cases this may result in depletion of available PM connection slots. +If the sysadmin expects connections to a single xfwp from many PM's, +xfwp should be started using the -pdt command line option, with a timeout +value reflecting the desired duration that inactive connections will be +permitted to remain open. + +Xfwp client listeners are set up by a call to xfindproxy and continue to +listen for X client connection requests for a default duration of 86,400 +seconds (24 hours) from the point of last activity. After this time they +are automatically closed and their fd's recovered for future allocation. +In addressing the question of how to choose some alternative timeout +value which will guarantee the availability of client listen ports, +sysadmins should take into consideration the expected delay between +the time when the listener was allocated (using xfindproxy) and the time +when a client actually attempts to connect to xfwp, as well the likelihood +that client listeners will be re-used after the initial client data +connection is closed. + +Each client connection is allocated a default lifetime of 604,800 +seconds (7 * 24 hours) +from the point when it last saw activity. After this time it is +automatically closed and its fd's recovered for future allocation. +Because server connections are not actually established until a connection +request from a remote X client arrives at one of the xfwp's client listen +ports, the client data timeout applies both to client-xfwp connections as well +as to xfwp-server connections. If the system administrator expects many +client data connections through xfwp, an overriding of the default timeout +should be considered. +.PP +.SH CONFIGURATION FILE +The xfwp configuration file resides on the xfwp host machine and is +used to determine whether X client data connection requests will be +permitted or denied. The path to the file is specified at start-up +time. If no configuration file is specified, all X client data +connection requests routed through xfwp will be by default permitted, +assuming that other X server authorization checks are successful. If +a configuration file is supplied but none of its entries matches the +connection request then the connection is by default denied. + +If a line in the configuration file begins with the '#' character +or a new-line character, the line is ignored and the evaluator will +skip the line. + +The configuration file supports two entirely independent authorization +checks: one which is performed by xfwp itself, and a second which is the +result of xfwp's querying the target X server. For the first of these, +the configuration file employs a syntax and semantic similar to that of IP +packet-filtering routers. It contains zero or more source-destination +rules of the following form: +.PP +{permit | deny} <src> <src mask> [<dest> <dest mask> [<operator> <service>]] +.sp +.IP permit/deny 12 +the keywords ``permit'' or ``deny'' indicate whether the +rule will enable or disable access, respectively +.IP src 12 +the IP address against the host who originated the +connection request will be matched, expressed in IP +format (x.x.x.x) +.IP "src mask" 12 +a subnet mask, also in IP format, for further qualifying +the source mask. Bits set in the mask indicate bits of the +incoming address to be \fIignored\fP when comparing to the specified src +.IP dest 12 +the IP address against which the destination of the +incoming connection request (i.e. the host IP of the +X server to which the incoming client is attempting to +connect) will be matched +.IP "dest mask" 12 +a subnet mask, also in IP format, for further qualifying +the destination mask. Bits set in the mask indicate bits of the +destination address to be \fIignored\fP when comparing to the specified dest +.IP operator 12 +always ``eq'' (if the service field is not NULL) +.IP service 12 +one of the following three strings: ``pm'', ``fp'', or +``cd'', corresponding to proxy manager, xfindproxy, or +client data, respectively +.PP +For the second type of authorization check, the configuration file contains +zero or more site policy rules of the following form: +.PP +{require | disallow} sitepolicy <site_policy> +.sp +.IP require 12 +specifies that the X server \fImust\fP be configured with \fIat least one\fP +of the corresponding site policies, else it must refuse the connection. +.IP disallow 12 +specifies that the X server \fImust not\fP be configured with \fIany\fP of +the corresponding site policies, else it must refuse the connection. +.IP sitepolicy 12 +a required keyword +.IP "<site_policy>" 12 +specifies the policy string. The string may contain any +combination of alphanumeric characters subject +only to interpretation by the target X server +.PP +.SH RULES FOR EVALUATING THE XFWP CONFIGURATION FILE ENTRIES +For the first type of configurable authorization checking, access +can be permitted or denied for each connection type based upon +source and, optionally, destination and service. Each file entry must +at a minimum specify the keyword ``permit'' or ``deny'' and the two +source fields. The +destination and service fields can be used to provide finer-grained +access control if desired. +.PP +The algorithm for rule-matching is as follows: +.PP +.RS 3 + while (more entries to check) + { + if ((<originator IP> AND (NOT <src mask>)) == src) + [if ((<dest X server IP> AND (NOT <dest mask>)) == dest)] + [if (service fields present and matching)] + do either permit or deny connection depending on keyword + else + continue + } + if (no rule matches) + deny connection +.RE +.PP +If a permit or deny rule does not specify a service and operation, then +the rule applies to all services. If a configuration file is specified +and it contains at least one valid deny or permit rule, then a host +that is not explicitly permitted will be denied a connection. +.PP +Site policy configuration checking constitutes a separate (and X server +only) authorization check on incoming connection requests. Any number of +require or disallow rules may be specified, but all rules must be of the +same type; that is, a single rule file cannot have both ``require'' and +``disallow'' keywords. The algorithm for this check is as follows: +.PP +.RS 3 + if (X server recognizes any of the site policy strings) + if (keyword == require) + permit connection + else + deny connection + else + if (keyword == require) + deny connection + else + permit connection +.RE +.PP +The site policy check is performed by xfwp only if the source-destination +rules permit the connection. +.PP +.SH +EXAMPLES +.PP +.sp +\fC +.nf +\&# if and only if server supports one of these policies then authorize +\&# connections, but still subject to applicable rule matches +\&# +require sitepolicy policy1 +require sitepolicy policy2 +\&# +\&# deny pm connections originating on 8.7.6.5 [NOTE: If pm service +\&# is explicitly qualified, line must include destination fields as +\&# shown.] +\&# +deny 8.7.6.5 0.0.0.0 0.0.0.0 255.255.255.255 eq pm +\&# +\&# permit xfindproxy X server connects to anywhere [NOTE: If +\&# fp service is explicitly qualified, line must include source fields +\&# as shown.] +\&# +permit 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255 eq fp +\&# +\&# permit all connection types originating from the 192.0.0.0 +\&# IP domain only +\&# +permit 192.0.0.0 0.255.255.255 +.fi +\fP +.PP +Care should be taken that source-destination rules are written in the correct +order, as the first matching rule will be applied.
