-DESCRIPTION -

-Redirects TCP connections from one IP address and port to another. rinetd -is a single-process server which handles any number of connections to -the address/port pairs specified in the file /etc/rinetd.conf. -Since rinetd runs as a single process using nonblocking I/O, it is -able to redirect a large number of connections without a severe -impact on the machine. This makes it practical to run TCP services -on machines inside an IP masquerading firewall. rinetd does not -redirect FTP, because FTP requires more than one socket. -

-rinetd is typically launched at boot time, using the following syntax: -

-/usr/sbin/rinetd -

-The configuration file is found in the file -/etc/rinetd.conf, unless -another file is specified using the -c command line option. -

-FORWARDING RULES -

-Most entries in the configuration file are forwarding rules. The -format of a forwarding rule is as follows: -

-bindaddress bindport connectaddress connectport
-
-For example: -
-206.125.69.81 80 10.1.1.2 80
-
-Would redirect all connections to port 80 of the "real" IP address -206.125.69.81, which could be a virtual interface, through -rinetd to port 80 of the address 10.1.1.2, which would typically -be a machine on the inside of a firewall which has no -direct routing to the outside world. -

-Although responding on individual interfaces rather than on all -interfaces is one of rinetd's primary features, sometimes it is -preferable to respond on all IP addresses that belong to the server. -In this situation, the special IP address 0.0.0.0 -can be used. For example: -

-0.0.0.0 23 10.1.1.2 23
-
-Would redirect all connections to port 23, for all IP addresses -assigned to the server. This is the default behavior for most -other programs. -

-Service names can be specified instead of port numbers. On most systems, -service names are defined in the file /etc/services. -

-Both IP addresses and hostnames are accepted for -bindaddress and connectaddress. -

-ALLOW AND DENY RULES -

-Configuration files can also contain allow and deny rules. -

-Allow rules which appear before the first forwarding rule are -applied globally: if at least one global allow rule exists, -and the address of a new connection does not -satisfy at least one of the global allow rules, that connection -is immediately rejected, regardless of any other rules. -

-Allow rules which appear after a specific forwarding rule apply -to that forwarding rule only. If at least one allow rule -exists for a particular forwarding rule, and the address of a new -connection does not satisfy at least one of the allow rules -for that forwarding rule, that connection is immediately -rejected, regardless of any other rules. -

-Deny rules which appear before the first forwarding rule are -applied globally: if the address of a new connection satisfies -any of the global allow rules, that connection -is immediately rejected, regardless of any other rules. -

-Deny rules which appear after a specific forwarding rule apply -to that forwarding rule only. If the address of a new -connection satisfies any of the deny rules for that forwarding rule, -that connection is immediately rejected, regardless of any other rules. -

-The format of an allow rule is as follows: -

-allow pattern
-
-Patterns can contain the following characters: 0, 1, 2, 3, 4, 5, -6, 7, 8, 9, . (period), ?, and *. The ? wildcard matches any one -character. The * wildcard matches any number of characters, including -zero. -

-For example: -

-

-allow 206.125.69.*
-
-This allow rule matches all IP addresses in the 206.125.69 class C domain. -

-Host names are NOT permitted in allow and deny rules. The performance -cost of looking up IP addresses to find their corresponding names -is prohibitive. Since rinetd is a single process server, all other -connections would be forced to pause during the address lookup. -

-LOGGING -

-rinetd is able to produce a log file in either of two formats: -tab-delimited and web server-style "common log format." -

-By default, rinetd does not produce a log file. To activate logging, add -the following line to the configuration file: -

-logfile log-file-location
-
-Example: -
-logfile /var/log/rinetd.log
-
-By default, rinetd logs in a simple tab-delimited format containing -the following information: -

-Date and time
-Client address
+

-Listening host -
-Listening port -
-Forwarded-to host -
-Forwarded-to port -
-Bytes received from client -
-Bytes sent to client -
-Result message -

-To activate web server-style "common log format" logging, -add the following line to the configuration file: -

-logcommon
-
-

-COMMAND LINE OPTIONS -

-The -c command line option is used to specify an alternate -configuration file. -

-The -h command line option produces a short help message. -

-The -v command line option displays the version number. -

-REINITIALIZING RINETD -

-The kill -1 signal (SIGHUP) can be used to cause rinetd -to reload its configuration file without interrupting existing -connections. Under Linux(tm) the process id -is saved in the file /var/run/rinetd.pid -to facilitate the kill -HUP. An alternate -file name can be provided by using the pidlogfile -configuration file option. -

-BUGS -

-The server redirected to is not able to identify the host the -client really came from. This cannot be corrected; however, -the log produced by rinetd provides a way to obtain this -information. Under Unix, sockets would theoretically lose data when closed -with SO_LINGER turned off, but in Linux this is not the case -(kernel source comments support this belief on my part). On non-Linux Unix -platforms, alternate code which uses a different trick to work around -blocking close() is provided, but this code is untested. -

-The logging is inadequate. The duration of the connection should be logged. -

DESCRIPTION

+ +

Redirects TCP connections from one IP address and port to another. rinetd +is a single-process server which handles any number of connections to the +address/port pairs specified in the file /etc/rinetd.conf. Since +rinetd runs as a single process using nonblocking I/O, it is able to redirect +a large number of connections without a severe impact on the machine. This +makes it practical to run TCP services on machines inside an IP masquerading +firewall. rinetd does not redirect FTP, because FTP requires +more than one socket.

+ +

rinetd is typically launched at boot time, using the following syntax:

+ +
/usr/sbin/rinetd
+ +

The configuration file is found in the file /etc/rinetd.conf, +unless another file is specified using the -c command line option. +

+ +

FORWARDING RULES

+ +

Most entries in the configuration file are forwarding rules. The format of +a forwarding rule is as follows: +

bindaddress bindport connectaddress connectport
+For example: +
206.125.69.81 80 10.1.1.2 80
+Would redirect all connections to port 80 of the “real” IP address +206.125.69.81, which could be a virtual interface, through rinetd to port 80 +of the address 10.1.1.2, which would typically be a machine on the inside of a +firewall which has no direct routing to the outside world.

+ +

Although responding on individual interfaces rather than on all interfaces +is one of rinetd's primary features, sometimes it is preferable to respond on +all IP addresses that belong to the server. In this situation, the special IP +address 0.0.0.0 can be used. For example: +

0.0.0.0 23 10.1.1.2 23
+Would redirect all connections to port 23, for all IP addresses assigned to the +server. This is the default behavior for most other programs.

+ +

Service names can be specified instead of port numbers. On most systems, +service names are defined in the file /etc/services.

+ +

Both IP addresses and hostnames are accepted for bindaddress and +connectaddress.

+ +

ALLOW AND DENY RULES

+ +

Configuration files can also contain allow and deny rules.

+ +

Allow rules which appear before the first forwarding rule are applied +globally: if at least one global allow rule exists, and the address of a new +connection does not satisfy at least one of the global allow rules, that +connection is immediately rejected, regardless of any other rules.

+ +

Allow rules which appear after a specific forwarding rule apply to that +forwarding rule only. If at least one allow rule exists for a particular +forwarding rule, and the address of a new connection does not satisfy at least +one of the allow rules for that forwarding rule, that connection is immediately +rejected, regardless of any other rules.

+ +

Deny rules which appear before the first forwarding rule are applied +globally: if the address of a new connection satisfies any of the global deny +rules, that connection is immediately rejected, regardless of any other rules. +

+ +

Deny rules which appear after a specific forwarding rule apply to that +forwarding rule only. If the address of a new connection satisfies any of the +deny rules for that forwarding rule, that connection is immediately rejected, +regardless of any other rules.

+ +

The format of an allow rule is as follows: +

allow pattern
+Patterns can contain the following characters: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, . +(period), ?, and *. The ? wildcard matches any one character. The * wildcard +matches any number of characters, including zero.

+ +

For example:

+ +

allow 206.125.69.*
+This allow rule matches all IP addresses in the 206.125.69 class C domain.

+ +

Host names are NOT permitted in allow and deny rules. The performance cost +of looking up IP addresses to find their corresponding names is prohibitive. +Since rinetd is a single process server, all other connections would be forced +to pause during the address lookup.

+ +

LOGGING

+ +

rinetd is able to produce a log file in either of two formats: +tab-delimited and web server-style “common log format.”

+ +

By default, rinetd does not produce a log file. To activate logging, add +the following line to the configuration file: +

logfile log-file-location
+Example: +
logfile /var/log/rinetd.log
+By default, rinetd logs in a simple tab-delimited format containing the +following information:

+ +
    +
  • Date and time
    • +
  • Client address
    +
  • Listening host
    • +
  • Listening port
    • +
  • Forwarded-to host
    • +
  • Forwarded-to port
    • +
  • Bytes received from client
    • +
  • Bytes sent to client
    • +
  • Result message
    • +
+ +

To activate web server-style “common log format” logging, add the following +line to the configuration file: +

logcommon
+

+ +

COMMAND LINE OPTIONS

+ +

The -c command line option is used to specify an alternate configuration +file.

+ +

The -f command line option is used to run rinetd in the foreground, without +forking to the background.

+ +

The -h command line option produces a short help message.

+ +

The -v command line option displays the version number.

+ +

REINITIALIZING RINETD

+ +

The kill -1 signal (SIGHUP) can be used to cause rinetd to reload +its configuration file without interrupting existing +connections. Under Linux(tm) the process id is saved in the file +/var/run/rinetd.pid to facilitate the kill -HUP. An alternate file +name can be provided by using the pidlogfile configuration file +option.

+ +

BUGS

+ +

The server redirected to is not able to identify the host the client +really came from. This cannot be corrected; however, the log produced by +rinetd provides a way to obtain this information. Under Unix, sockets would +theoretically lose data when closed with SO_LINGER turned off, but +in Linux this is not the case (kernel source comments support this belief on +my part). On non-Linux Unix platforms, alternate code which uses a different +trick to work around blocking close() is provided, but this code +is untested.

+ +

The logging is inadequate. The duration of the connection should be logged. +
