Multiple Servers

[da3533]

hi..

i have 1 server which can be accessed through one main direct ip address. i want another server to be used as well this one. how do i somehow, gain access to the new server externally?

so basically, for now, if i type in my current IP, it will show the main default page on server 1.. is there any way i can do the following:- configure- 82.34.232.33:566 (port 566 to forward to lan ip of server 2) .. so if some one types in 82.34.232.33:566 in their web browser, they will be directed to server 2...?

might sound stupid, sorry.

Yeah that is definitely within the realms of standard port forwarding.

is your router doing the port forwarding, or is the server on a public IP?

hey..

i configured DMZ pointed to my servers local LAN IP address. so the real ip is direct to my server. i have a netgear router... i tried to add a service in but it doesnt work. how shall i configure this? i want it so that if anyone types in IP is 80.43.343.20:233 , it will go where i want it to go. (server2).. i know how to configure server2 so that it will respond if this ip and port of 233 is called..

diagram of what i want:

type --> http://80.43.343.20 --> server1 done!

type --> http://80.43.343.20:233 --> server2 not done!

if this works, i can just change the DNs of my domains to point to 80.43.343.20:233 if i want to be hosted from server 2 or 80.43.343.20 if i want it to be hosted from server1..

(all hosting of all servers have been taken care of)

ah well that's pretty easy with xinetd

vim /etc/xinetd.d/other_server

paste

# default: off
service other_server
{
        disable = no
        socket_type = stream
        protocol = tcp
        port = 233
        wait = no
        user = nobody
        redirect = 192.168.1.50 80
}

vim /etc/services
paste at the end

#Local services

other_server        233/tcp

Now run:
sudo /etc/init.d/xinetd reload

and connect to http://80.43.343.20:233 in your web browser

You can do the xinetd method outlined above.

However, you can also easily do that with your router.

Simply disable your DMZ (not a very good idea anyways) and then the router should have a page to forward ports. If you go to portforward.com, they have pretty good guides on how to do this. Basically you tell port 80 to forward to one IP, and port 233 (or whatever) to forward to the other server's IP.

I just wouldn't advise keeping that DMZ up. You should only open up ports your server is listening on.

thanks! it works.

hey.. it works... but my problems not solved .. i aim was to add this ip with the port number to my account at DynDNS.org . this way i could have had a hostname directing to 80.43.343.20:233 but dyndna.org states that you cant have a port number with the IP as the IP add for this hostname...

so basically, i wanted, serv2.server22.org to point to 80.43.343.20:233 but no joy


any suggestions?

You need to purchase another IP from your provider, unfortunately. Dyndns won't redirect based on port numbers, they must be unique IP addresses.

I thought you were going to give out the different port numbers for your site... So site1 was google.com:80 and site2 was google.com:233. Not pretty, but I thought you knew what you were getting into

I'd still recommend collapsing that DMZ as well. Just something to think about.

im on the process of disabling it but need it for this time while installing everything...

purchase another IP... hmm.. this is going to cost.. never looked into it.. there must be way round this though, i tried this and failed in the last part. i actually thought they would allow port numbers.. so if you have 20 servers, you will need 20 IPs?
