AFAIK, and indeed what I use for DDNS, ddclient is the best solution.

Slackpack: http://slackbuilds.org/repository/13...work/ddclient/
Documentation: http://sourceforge.net/apps/trac/ddclient#Configuration
More documentation: http://sourceforge.net/apps/trac/ddclient/wiki/Usage

I setup ddclient , all is well and I can get to my adsl router from the outside
But I cant access my server , router is 192.168.1.1 and server 192.168.1.3

That is were I have my wheels come off and crash and burn

have you setup up the adsl router to do port forwarding?

what service exactly do you want to 'see' on your server from the 'outside'?

but have you done port forwarding?

If not, go to your router's configuration webpage and look for something like 'port forwading' or 'NAT'. there you can let the world access your internal server on port 80.

here is some guidance

@nass

Yes I have port forwarding working , I can access my ERP server at {domain}.co.za:8069

But when i try and access my web server , I get error reading from remote server ..

Is this a Apache problem or am i missing something , to eliminate port numbers I am forwarding all ports from 1 to 65535

I am lost in this abyss now

Hi,

A mess is what I quickly read from the posts, but

Quote:

bothers me,
meaning your server doesn't run Apache/httpd service (have you started it ?) and router is not forwarding port 80 to your server (you get router's web panel ?)

Quote:

.. to eliminate port numbers I am forwarding all ports from 1 to 65535

and you should also post a model of your router for someone could have done it with the same router or can be searched for a solution.
There is maybe a PORT TRIGGER also in your router settings, which should be set to trigger port 80 to your server's IP.

good luck

Have you, in /etc/httpd.conf, edited

Code:

# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
#Listen 80
Listen  192.168.1.3:80          < this is your server address

and

Code:

# If your host doesn't have a registered DNS name, enter its IP address here.
#
#ServerName www.example.com:80
ServerName fubar.com:80         < your server name goes here

If not, do the above then

Code:

/etc/rc.d/rc.httpd restart

In your router, make sure that port 80 is forwarded; you do not need, nor do you want, to forward every port, only the ones you need like 80 and 22 to start with -- you can add or change after you get things going.

Hope this helps some.

I forgot to include a working /etc/ddclient/ddclient.conf for you:

Code:

## ddclient configuration file
daemon=600
# check every 600 seconds
syslog=yes
# log update msgs to syslog
mail-failure=your_e-mail_address_goes_here # Mail failed updates to user
pid=/var/run/ddclient.pid
# record PID in file.
## Detect IP with our CheckIP server
use=web, web=checkip.dyndns.com/, web-skip='IP Address'
## DynDNS username and password here
login=userid_goes_here
password=password_goes_here
## Default options
protocol=dyndns2
server=members.dyndns.org
## Dynamic DNS hosts
you_dyndns_site_name_goes_here

This assumes that you're registered with DynDNS, have a login and password and have chosen a web site name. It would be something like billybob.dyndns.org.

Note that you do not enter any of this stuff in /etc/httpd/httpd.conf, that's your local system name, domain and address (192.168.1.3).

Hope this helps some.
