[gentoo-user] ddclient question

[krgn]

hello,

I have a few questions on how to basically access a specific machine in 
a network from the web. I have registered with dyndns.org and got 
ddclient running to provide the ip address, but the only thing I can now 
connect to is my network router ;) which is pretty useless. How would it 
be possible o change the setup for a machine within the smaller 
home-network? Does that have to do with the setup on dyndns or in the 
config file of ddclient?
I can paste its content if needed, any advice and tips would be greatly 
appreciated!

Thanks,

Karsten

This doesn't have anything to do with ddclient or dyndns, as long as the dns 
entry is pointing to the right ip then it's doing all it should.

Your router should provide the ability to configure port forwarding to 
machines in your LAN. Simply configure it to forward traffic on whatever 
ports you want to use to the clients which are serving those ports. The 
router may also provide a DMZ function which will forward all incoming 
traffic to a specific machine on your LAN, although this may possible make 
the machine vulnerable to security exploits.

You'll have to read the documentation that came with the router or search 
google in order to configure it appropriately as the configuration details 
differ between manufacturers and models.

hm ok, but lets say for instance my machines hostname is "mymachine", 
its port is 'xxxx' and the address which points to the router is 
"myaddress.dyndns.org": what would be for example the ssh command to 
connect to that particular machine? I know its a bit of a stupid 
question, but I can't picture what this would look like/how it would 
work. I must saz understanding these network issues really is a bit 
tricky for me at the moment,

thanks for your help anyway,

$ ssh -p xxxx myaddress.dyndns.org

Of course, you'll need to have configured the router to forward that 
particular port to "mymachine".
