## INSTALLATION
|
|
|
|
### Distribution Package

|
|
The easiest way to install ddclient is to install a package offered by your
|
|
operating system. See the image to the right for a list of distributions with a
|
|
ddclient package.
|
|
|
|
### Manual Installation
|
|
|
|
1. Extract the distribution tarball (`.tar.gz` file) and `cd` into
|
|
the directory:
|
|
|
|
```shell
|
|
tar xvfa ddclient-3.10.0.tar.gz
|
|
cd ddclient-3.10.0
|
|
```
|
|
|
|
(If you are installing from a clone of the Git repository, you
|
|
must run `./autogen` before continuing to the next step.)
|
|
|
|
2. Run the following commands to build and install:
|
|
|
|
```shell
|
|
./configure \
|
|
--prefix=/usr \
|
|
--sysconfdir=/etc/ddclient \
|
|
--localstatedir=/var
|
|
make
|
|
make VERBOSE=1 check
|
|
sudo make install
|
|
```
|
|
|
|
3. Edit `/etc/ddclient/ddclient.conf`.
|
|
|

service ddclient start
|
|
|
|
|
|
If you are not using daemon-mode, configure cron and dhcp or ppp as described below.
|
|
|
|
## TROUBLESHOOTING
|
|
|
|
1. enable debugging and verbose messages: ``$ ddclient -daemon=0 -debug -verbose -noquiet``
|
|
|
|
2. Do you need to specify a proxy?
|
|
If so, just add a ``proxy=your.isp.proxy`` to the ddclient.conf file.
|
|
|
|
3. Define the IP address of your router with ``fw=xxx.xxx.xxx.xxx`` in
|
|
``/etc/ddclient/ddclient.conf`` and then try ``$ ddclient -daemon=0 -query`` to see if the router status web page can be understood.
|
|
|
|
4. Need support for another router/firewall?
|
|
Define the router status page yourself with: ``fw=url-to-your-router``'s-status-page ``fw-skip=any-string-preceding-your-IP-address``
|
|
|
|
ddclient does something like this to provide builtin support for
|
|
common routers.
|
|
For example, the Linksys routers could have been added with:
|
|
|
|
fw=192.168.1.1/Status.htm
|
|
fw-skip=WAN.*?IP Address
|
|
|
|
OR
|
|
Send me the output from:
|
|
``$ ddclient -geturl {fw-ip-status-url} [-login login [-password password]]``
|
|
and I'll add it to the next release!
|
|
|
|
ie. for my fw/router I used: ``$ ddclient -geturl 192.168.1.254/status.htm``
|
|
|
|
5. Some broadband routers require the use of a password when ddclient
|
|
accesses its status page to determine the router's WAN IP address.
|
|
If this is the case for your router, add
|
|
|
|
fw-login=your-router-login
|
|
fw-password=your-router-password
|
|
|
|
to the beginning of your ddclient.conf file.
|
|
Note that some routers use either 'root' or 'admin' as their login
|
|
while some others accept anything.
|
|
|
|
## USING DDCLIENT WITH `ppp`
|
|
|
|
If you are using a ppp connection, you can easily update your DynDNS
|
|
entry with each connection, with:
|
|
|
|
## configure pppd to update DynDNS with each connection
|
|
cp sample-etc_ppp_ip-up.local /etc/ppp/ip-up.local
|
|
|
|
Alternatively, you may just configure ddclient to operate as a daemon
|
|
and monitor your ppp interface.
|
|
|
|
## USING DDCLIENT WITH `cron`
|
|
|
|
If you have not configured ddclient to use daemon-mode, you'll need to
|
|
configure cron to force an update once a month so that the dns entry will
|
|
not become stale.
|
|
|
|
## configure cron to force an update twice a month
|
|
cp sample-etc_cron.d_ddclient /etc/cron.d/ddclient
|
|
vi /etc/cron.d/ddclient
|
|
|
|
## USING DDCLIENT WITH `dhcpcd-1.3.17`
|
|
|
|
If you are using dhcpcd-1.3.17 or thereabouts, you can easily update
|
|
your DynDNS entry automatically every time your lease is obtained
|
|
or renewed by creating an executable file named:
|
|
``/etc/dhcpc/dhcpcd-{your-interface}.exe``
|
|
ie.:
|
|
``cp sample-etc_dhcpc_dhcpcd-eth0.exe /etc/dhcpc/dhcpcd-{your-interface}.exe``
|
|
|
|
In my case, it is named dhcpcd-eth0.exe and contains the lines:
|
|
|
|
```shell
|
|
#!/bin/sh
|
|
PATH=/usr/bin:/root/bin:${PATH}
|
|
logger -t dhcpcd IP address changed to $1
|
|
ddclient -proxy fasthttp.sympatico.ca -wildcard -ip $1 | logger -t ddclient
|
|
exit 0
|
|
```
|
|
|
|
Other DHCP clients may have another method of calling out to programs
|
|
for updating DNS entries.
|
|
|
|
Alternatively, you may just configure ddclient to operate as a daemon
|
|
and monitor your ethernet interface.
|
|
|
|
## USING DDCLIENT WITH `dhclient`
|
|
|
|
If you are using the ISC DHCP client (dhclient), you can update
|
|
your DynDNS entry automatically every time your lease is obtained
|
|
or renewed by creating an executable file named:
|
|
``/etc/dhclient-exit-hooks``
|
|
ie.:
|
|
``cp sample-etc_dhclient-exit-hooks /etc/dhclient-exit-hooks``
|
|
|
|
Edit ``/etc/dhclient-exit-hooks`` to change any options required.
|
|
|
|
Alternatively, you may just configure ddclient to operate as a daemon
|
|
and monitor your ethernet interface.
