INSTALLATION
Distribution Package
Manual Installation
Extract the distribution tarball (
.tar.gzfile) andcdinto the directory:tar xvfa ddclient-3.9.1.tar.gz cd ddclient-3.9.1(If you are installing from a clone of the Git repository, you must run
./autogenbefore continuing to the next step.)Run the following commands to build and install:
./configure \ --prefix=/usr \ --sysconfdir=/etc/ddclient \ --localstatedir=/var make make VERBOSE=1 check sudo make installEdit
/etc/ddclient/ddclient.conf.
systemd
cp sample-etc_systemd.service /etc/systemd/system/ddclient.service
enable automatic startup when booting
systemctl enable ddclient.service
start the first time by hand
systemctl start ddclient.service
Redhat style rc files and daemon-mode
cp sample-etc_rc.d_init.d_ddclient /etc/rc.d/init.d/ddclient

make sure you have perl installed
apk add perl
start the first time by hand

Ubuntu style rc files and daemon-mode
cp sample-etc_rc.d_init.d_ddclient.ubuntu /etc/init.d/ddclient
enable automatic startup when booting
update-rc.d ddclient defaults
make sure you have perl and the required modules installed
apt-get install perl libdata-validate-ip-perl libio-socket-ssl-perl
if you plan to use cloudflare or feedns you need the perl json module
apt-get install libjson-pp-perl
for IPv6 you also need to instal the perl io-socker-inet6 module
apt install libio-socket-inet6-perl
start the first time by hand
service ddclient start
FreeBSD style rc files and daemon mode
mkdir -p /usr/local/etc/rc.d
cp sample-etc_rc.d_ddclient.freebsd /usr/local/etc/rc.d/ddclient
enable automatic startup when booting
sysrc ddclient_enable=YES
make sure you have perl and the required modules installed
pkg install perl5 p5-Data-Validate-IP p5-IO-Socket-SSL
if you plan to use cloudflare or feedns you need the perl json module
pkg install p5-JSON-PP
start the service manually for the first time
service ddclient start
If you are not using daemon-mode, configure cron and dhcp or ppp as described below.
TROUBLESHOOTING
enable debugging and verbose messages:
$ ddclient -daemon=0 -debug -verbose -noquietDo you need to specify a proxy? If so, just add a
proxy=your.isp.proxyto the ddclient.conf file.Define the IP address of your router with
fw=xxx.xxx.xxx.xxxin/etc/ddclient/ddclient.confand then try$ ddclient -daemon=0 -queryto see if the router status web page can be understood.Need support for another router/firewall? Define the router status page yourself with:
fw=url-to-your-router's-status-pagefw-skip=any-string-preceding-your-IP-addressddclient 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
- 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:
#!/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 0Other 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.
