Basically I have a Debian box running asterisk assigned an IP via DHCP with host-name XXX. My windows browser can resolve the host-name but if I use host-name in X-Lite or my SPA922 phone it fails to resolve. Is there any way of getting this to work without depending on the router or assigning a static IP (request is to make it portable). I was thinking zero-conf but am unsure (box has limited HDD too). Any help is most appreciated.
There are a couple of ways you could do this.
Personally I replaced my stock router firmware with DD-WRT and it then serves as both the DHCP server and supports a local name server (so all machines on the local LAN can access each other by name).
Not quite "not depending on the router" but pretty low configuration, and nothing to configure at all on the client devices really.

I am using Nodejs with the express, bcrypt and body-parser packages on an ubuntu linux system.
Everything works fine so far.
However, I´ve been wondering if there is an easier way to connect to my website.
Until now, I have to type in my IP adress, e.g. https://XXX.XXX.XXX:3000 to actually see the content.
I´ve already tried avahi-daemon but did not get it work. Whenver I try 'hostname.local' I get the same error: Firefox is unable to connect to server.
However, using the IP-Adress: https://XXX.XXX.XXX:3000 works.
I would like to access my NodeJS sever with something similar to: computername.local
FYI: I just want to use it in my local network at home.
Does anybody have any idea how to get this work?
You have a couple choices. The easiest,if available, is probably to setup your home router to always assign it the same IP address (how to do that will vary based on your router). If your router has it available, you could also set a host name for it there in DNS settings.
If your router doesn't have DNS settings available, then you can add a line to each of your home computers /etc/hosts file (if memory serves Windows has it in C:\etc\hosts). Let's say the IP you give the server is 172.16.1.11, your hosts entry would be
172.16.1.11 computername.local
You could also setup your own DNS server in your house, possibly even on the same machine as has your node app, and then configure it to handle the one address before forwarding DNS requests for others to your ISP but that seems like overkill if you have just one app.
This might be a stupid question, but i run a business in a strip mall and internet is included (because of this I have no access to the router). the router assigns dynamic ip address and when I set a static ip I lose connection.
is there a way to change the address to my node app from "http:/ /[my-server-ip]:3000" to something like "http:/ /[business-name]:3000". (/ / should be // but stack wont let me post with dead links)
the main reason for this is I have multiple tablets and devices that use this system however recently after they made some changes to the routers setting my computer will be assigned two or three ip addresses a day (I notified the landlord he says its normal). and everytime my ip address changes I lose connection to my app.
is there a possible fix that doesnt require me to host on a web server or enable port forwarding?
perhaps I should reword the question. How do I go about setting up local dns zones from mac? (I know this can be achieved with most linux distros)
No you can't.
Your server IP will always change as the router gives you a new IP address, so change the hosts will not work unless every time the ip on the server changes, you change your ip as well on the devices.
You may try to create an account on dns sites like http://www.noip.com/. They will give you an "external" internet address like mybusiness.noip.com and then you will point your programs on tablets and cell phones to this address.
You will then install a program on your server that will tell noip what the new address is maintaining the same mybusiness.noip.com on them.
Hi I have a Huawei ADSL modem with a dynamic IP. I set up a dynamic dns with freedns and I can easily access my Virtual host on apache from outside my private network, from internet.
So trying to access it from a local network I get a modems login page.
I have the rule in my modems NAT to connect port 80 to my server but it seems it doesnt work from internal net.
My server hosting the virtual host is 192.168.0.1 , the modem has the 192.168.0.254 address.
I tried to put my external domain name into the /etc/hosts file, but if I do that then asterisk server gets confused.
What could be the cause of the problem ? And what would be the best solution to this problem ?
Should I set up a caching DNS on the private side of the net ?
Hugger is half right... Its because your router is blocking loopbacks. The easiest way around this is to edit the hosts file (See the Wiki page) on the computer that is behind the network to see the local IP of the computer as the virtual host your going for. For example if your server is on 192.168.0.1 and the virtual hostname is www.imrad.com then insert
192.168.0.1 www.imrad.com
into your hosts file. If your computer leaves the local network (like a laptop you take to work) and joins a network not behind your router you need to comment out the line in the hosts file.
well actually to access that you must find the local ip address of the server by going into command line/prompt and typing ipconfig /all then you will find ipv4 address. Take note of that.
Go to another computer and your that ip and it will show.
The reason that was happening is because the router/modem knows you are in its network so it will think you ar trying to go top the login page of it. That happens to me too.
I want build a router to control my internet access (wlan via server).
Only a few websites (via white/blacklist) should be available at specific times.
Are there any good packages for routing/proxying web (http/s, ftp) and email (pop/imap/smtp) traffic?
What you actually need is a good Firewall. Any decent firewall should be able to filter traffic by day-of-week and time-of-day. Even many of the better SOHO routers can do this. If your router can't do this, you should use a spare PC or server to act as a gateway, run Linux or BSD on that and configure a firewall accordingly. Most Linux versions have IPTABLES which is a simple but effective firewall which will do what you want.
To make things easy, set the PC up to be the DHCP server for the network and configure it so that, when other PC's get an IP address, the gateway IP is set to the same box (you may be able to get your normal router to do this instead otherwise turn off DHCP on the router).
Ideally, if using a gateway PC, set your routers to ONLY accept traffic from that gateway - better still, turn off NAT on the router and let the gateway do it too.
Here is a fairly comprehensive "how-to".
If all of that seems too much, you should consider upgrading your router to one that does all this for you. I personally use the Billion 7800N which would probably be suitable.
If you need an HTTP proxy check out node-http-proxy. I don't know much about FTP and mail proxies though.
I've been developing locally on a little ubuntu netbook with xampp for about 7 months. Two weeks ago I got a computer I'd like to use as a server. I've installed the latest Ubuntu distribution and xampp, moved all my files over, and forwarded port 80. I've also got a domain name from dyndns.com which is being updated by a client which runs in my router (a Netgear WGR6154 v8).
Now, when I try to access my server by typing in the address I got from dyndns.com the browser loads until it timesout. I can access everything locally using localhost as the address so I believe xampp is running, just unable to connect with the internet.
In order to be able to view my files over the internet what should I do next?
Thanks to all in advance...

You have a combination of issues here, and that is something of a problem. Each issue is complex in an of itself. Here is what I would recommend to get you going for certain.
First verify that you can surf the web from your server. This will confirm that you have a working ethernet interface.
Step 1 make sure that XAMPP, and your files are viewable from your home network. I assume you are using something like 192.168.1.X for your network and perhaps your server is 192.168.1.10
Go to another computer in your house and type http://192.168.1.10/ and see if you can see your files. If you can then you know that the server is properly configured and XAMPP is working.
Then add an entry to your hosts file to resolve yourdnsrecord.com (or whatever your dyndns record is) to your private ip address. Then when you type yourdnsrecord.com into a browser from that computer you should still get your files. This will rule out your server being improperly configured to listen for that domain name.
Next you need to test to see if there is a firewall problem. To simplify this, first remove your home router from the equation. Instead, place your new server directly onto your internet connection. (assuming you can). This way, you do not need to have NAT or firewalls properly configured. Your dyndns name should map to a public IP and your server should then have that IP and be connected directly to the Internet. If you have your server directly connected, and the command ifconfig from the root prompt returns the same public IP address that your dynamic dns record is point to, then it should work.
It will make your life easier if you have an iphone or some other way to test how your network is seen from the Internet.
If your public IP as shown by ifconfig is different than the IP record in your dyndns account, then your dynamic dns update script is broken. manually set the IP, and see if things work.
It is very possible that this will not work. Some ISPs firewall port 80 preventing their subscribers from hosting servers. Once you have your server directly connected to the internet you can test this (even if your dns is not working) by using the public IP address. As root, type ifconfig from the command prompt to get your public ip address. Then type the command tcpdump -i eth? port 80 from the root prompt. eth? needs to be the same interface that you saw had a public IP address from the ifconfig command. usually this is eth0 but it might be wire0 or something like that.
This command will show you all traffic coming on port 80 to your server.
From an iphone (or whatever second Internet connection you have) browse to the IP address that you got from your ifconfig command. If you see something on your server (and it is directly connected to your ISP) then your ISP is not firewalling you.
If you can get to your server, when it is directly connected to the Internet, either by IP address or by DynDNS address, then your ISP is OK and it is time to debug your firewall.
Two things need to work for your firewall to be configured NAT, where the public address that your router gets from your ISP is converted into your private network and a firewall rule which permits that traffic. If you get this far, then you know your firewall is the problem and then it is just a matter of getting its configuration correct. There are far to many home routers to document here, but you usually can find how-to instructions for your router for this task from the manufacturers website (usually it is part of the manual)
If you follow these instructions exactly you will get your system working. Make comments on the process and I will be happy to modify this to make it clearer.
HTH,
-FT
You should make sure your xampp is not listening to only the localhost.
to do so edit your apache configuration file and check and search for Listen directive
you should be able to know also by analysing the output of netstat -a.
After that make sure your router is forwarding properly, using tcpdump would help.
drop me a comment if you need more help.
