This file describes noip2, a second-generation Linux client for the no-ip.com dynamic DNS service.

NEW: This code will build and run on Solaris/Intel and BSD also. Edit the Makefile for Solaris and the various BSDs. For BSD users wanting to use a tun interface, see below. Let me know about any other changes needed for noip2 to operate correctly on your non-Linux OS.

Please read this short file before using noip2.

########################################################################## # HOW TO BUILD AN EXECUTABLE FOR YOUR SYSTEM

The command make will build a binary of the noip2 client that will run on your system.

If you do not have 'make' installed and you have an i686 Linux machine with libc6, a binary for i686 systems is located in the binaries directory called noip2-Linux. Copy that binary to the build directory 'cp binaries/noip2-Linux noip2'

The command make install (which must be run as root) will install the various pieces to their appropriate places. This will ask questions and build a configuration data file. See below if you can't become root or can't write in /usr/local/*.

########################################################################## # HOW TO USE THE CLIENT WITHOUT READING THE REST OF THIS TEXT

Usual operation? /usr/local/bin/noip2 -C configure a client /usr/local/bin/noip2 run a client /usr/local/bin/noip2 -S display info about running clients /usr/local/bin/noip2 -D pid toggle the debug state for client pid /usr/local/bin/noip2 -K pid terminate client pid

Have more than one internet access device? /usr/local/bin/noip2 -M -c file start additional instances

########################################################################## # HOW TO START THE CLIENT

The noip2 executable can be run by typing /usr/local/bin/noip2

If you want it to run automatically when the machine is booted, then place the following script in your startup directory. (/etc/init.d/rcX.d or /sbin/init.d/rcX.d or ???)

####################################################### #! /bin/sh # . /etc/rc.d/init.d/functions # uncomment/modify for your killproc case "$1" in start) echo "Starting noip2." /usr/local/bin/noip2 ;; stop) echo -n "Shutting down noip2." killproc -TERM /usr/local/bin/noip2 ;; *) echo "Usage: $0 {start|stop}" exit 1 esac exit 0 #######################################################

Where the 'X' in rcX.d is the value obtained by running the following command grep initdefault /etc/inittab | awk -F: '{print $2}'

Killproc can be downloaded from ftp://ftp.suse.com/pub/projects/init Alternatively, you can uncomment the line after #! /bin/sh

If you have a recent RedHat version, you may want to use the startup script supplied by another user. It's in this package called redhat.noip.sh It may need some modification for your system.

There is a startup script for Debian called debian.noip2.sh. It also has been supplied by another user and is rumored to fail in some situations.

Here is a script which will kill all running copies of noip2. #!/bin/sh for i in `noip2 -S 2>&1 | grep Process | awk '{print $2}' | tr -d ','` do noip2 -K $i done These four lines can replace 'killproc' and 'stop_daemon' in the other scripts.

If you are behind a firewall, you will need to allow port 8245 (TCP) through in both directions. #######################################################################

IMPORTANT!! Please set the permissions correctly on your executable. If you start noip2 using one of the above methods, do the following: chmod 700 /usr/local/bin/noip2 chown root:root /usr/local/bin/noip2 If you start noip2 manually from a non-root account, do the chmod 700 as above but chown the executable to the owner:group of the non-root account, and you will need to substitute your new path if the executable is not in /usr/local/bin.

########################################################################## # SAVED STATE

Noip2 will save the last IP address that was set at no-ip.com when it ends. This setting will be read back in the next time noip2 is started. The configuration data file must be writable for this to happen! Nothing happens if it isn't, the starting 0.0.0.0 address is left unchanged.

########################################################################## # BSD USING A TUN DEVICE

Recent BSD systems will use getifaddrs() to list ALL interfaces. Set the 'bsd_wth_getifaddrs' define in the Makefile if using a version of BSD which supports getifaddrs() and ignore the rest of this paragraph. Otherwise set the 'bsd' define. The 'bsd' setting will not list the tun devices in BSD. Therefore a tun device cannot be selected from the menu. If you want to use a tun device you will need to edit the Makefile and change the line ${BINDIR}/${TGT} -C -Y -c /tmp/no-ip2.conf to ${BINDIR}/${TGT} -C -Y -c /tmp/no-ip2.conf -I 'your tun device'

########################################################################## # COMMAND LINE ARGUMENTS WHEN INVOKING THE CLIENT

The client will put itself in the background and run as a daemon. This means if you invoke it multiple times, and supply the multiple-use flag, you will have multiple instances running.

If you want the client to run once and exit, supply the '-i IPaddress' argument. The client will behave well if left active all the time even on intermittent dialup connections; it uses very few resources.

The actions of the client are controlled by a configuration data file. It is usually located in /usr/local/etc/no-ip2.conf, but may be placed anywhere if the '-c new_location' parameter is passed on the startup line.

The configuration data file can be generated with the '-C' parameter.

There are some new command line arguments dealing with default values in the configuration data file. They are -F, -Y and -U.

The interval between successive testing for a changed IP address is controlled the '-U nn' parameter. The number is minutes, a minimum of 1 is enforced by the client when running on the firewall machine, 5 when running behind a router/firewall. A usual value for clients behind a firewall is 30. One day is 1440, one week is 10080, one month is 40320, 41760, 43200 or 44640. One hour is left as an exercise for the reader :-)

The configuration builder code will allow selection among the hosts/groups registered at no-ip.com for the selected user. The '-Y' parameter will cause all the hosts/groups to be selected for update.

Some sites have multiple connections to the internet. These sites confuse the auto NAT detection. The '-F' parameter will force the non-NAT or "firewall" setting.

The client can be invoked with the '-i IPaddress' parameter which will force the setting of that address at no-ip.com. The client will run once and exit.

The -I parameter can be used to override the device name in the configuration data file or to force the supplied name into the configuration data file while it is being created. Please use this as a last resort!

The '-S' parameter is used to display the data associated with any running copies of noip2. If nothing is running, it will display the contents of the configuration data file that is selected. It will then exit.

The '-K process_ID' parameter is used to terminate a running copy of noip2. The process_ID value can be obtained by running noip2 -S.

The '-M' parameter will permit multiple running copies of the noip2 client. Each must have it's own configuration file. Up to 4 copies may run simultaneously.

All errors and informational messages are stored via the syslog facility. A line indicating a successful address change at no-ip.com is always written to the syslog. The syslog is usually /var/log/messages.

If the client has been built with debugging enabled, the usual state, the '-d' parameter will activate the debug output. This will produce a trace of the running program and should help if you are having problems getting the connection to no-ip.com established. All errors, messages and I/O in both directions will be displayed on the stderr instead of syslog. The additional '-D pid' parameter will toggle the debug state of a running noip2 process. This will not change where the output of the process is appearing; if it was going to the syslog, it will still be going to the syslog.

One final invocation parameter is '-h'. This displays the help screen as shown below and ends.

USAGE: noip2 [ -C [ -F][ -Y][ -U #min]][ -c file] [ -d][ -D pid][ -i addr][ -S][ -M][ -h]

Version Linux-2.x.x Options: -C create configuration data -F force NAT off -Y select all hosts/groups -U minutes set update interval -c config_file use alternate data path -d increase debug verbosity -D processID toggle debug flag for PID -i IPaddress use supplied address -I interface use supplied interface -S show configuration data -M permit multiple instances -K processID terminate instance PID -h help (this text)

########################################################################## # HOW TO CONFIGURE THE CLIENT

The command noip2 -C will create configuration data in the /usr/local/etc directory. It will be stored in a file called no-ip2.conf.

If you can't write in /usr/local/*, or are unable to become root on the machine on which you wish to run noip2, you will need to include the '-c config_file_name' on every invocation of the client, including the creation of the datafile. Also, you will probably need to put the executable somewhere you can write to. Change the PREFIX= line in the Makefile to your new path and re-run make install to avoid these problems.

You will need to re-create the datafile whenever your account or password changes or when you add or delete hosts and/or groups at www.no-ip.com Each invocation of noip2 with '-C' will destroy the previous datafile.

Other options that can be used here include '-F' '-Y' -U'

You will be asked if you want to run a program/script upon successful update at no-ip.com. If you specify a script, it should start with #!/bin/sh or your shell of choice. If it doesn't, you will get the 'Exec format error' error. The IP address that has just been set successfully will be delivered as the first argument to the script/program. The host/group name will be delivered as the second argument.

Some machines have multiple network connections. In this case, you will be prompted to select the device which connects to outside world. The -I flag can be supplied to select an interface which is not shown. Typically, this would be one of the pppx interfaces which do not exist until they are active.

The code will prompt for the username/email used as an account identifier at no-ip.com. It will also prompt for the password for that account.

The configuration data contains no user-serviceable parts!!

IMPORTANT!! Please set the permissions correctly on the configuration data. chmod 600 /usr/local/etc/no-ip2.conf. chown root:root /usr/local/etc/no-ip2.conf. If you start noip2 manually from a non-root account, do the chmod as above but chown the no-ip2.conf file to the owner:group of the non-root account. Make sure the directory is readable!

The program will drop root privileges after acquiring the configuration data file. ########################################################################## #
