Getting Started with CouchDB - couchdb

I've got CouchDB installed on my linux cloud server and I'm trying to access the "Futon Welcome Screen". The O'Reilly book says to go to "127.0.0.1:portnum", but I'm not working on localhost, it is my remote server, so I should be able to use "xxx.xxx.xxx.x:portnum" (my remote address) to access Futon right? This is not working, do I need a virtual host or something? Thanks.

Go to your local.ini file. (probably in /etc/couchdb) and set bind_address to either 0.0.0.0 (ie. respond to all IP addresses) or specify another IP address that you're either using in your LAN (private) or over the internet. (public)

How to access CouchDB installed on another machine?

We have CouchDB installed on a separate machine.
When it was installed on my machine, it was accessible through Fauxton via link http://localhost:5984/_utils/index.html
Also, I am using Divan, a C# library to interact with CouchDB. It uses host as localhost and port as 5984 - default host and port names to connect with database.
But now I have CouchDB installed on another machine, how can I access it in this case?
Please suggest.
Thank you.
You need to allow exterior access in the new machine (which I'll just call the server). Your computer is the client. First, make sure the server is accessible from your network and get its IP address using ipconfig or ifconfig in the command line.
First, in the server, open the CouchDB configuration file, which is
/usr/local/etc/couchdb/local.ini in Linux
or
C:\Program Files\CouchDB\etc\couchdb\local.ini in Windows
and change
[httpd]
bind_address = 127.0.0.1
to
[httpd]
bind_address = 0.0.0.0
If there is no bind_address already in the file, just add it.
Then save the file.
Now, from the client, you can access futon from your machine using {SERVER_IP}:5984/_utils.
In Divan, set host to {SERVER_IP}. Unless you configure it otherwise, the port remains 5984.

(*) I'm assuming you're using CouchDB 2.0, but in my experience with 1.6.1 this instructions also work.
Connect to your server locally:
localhost:5984/_utils
then simply from the setting section, change the bind_address to 0.0.0.0

Accessing a server using VPN connection

I am trying to connect to a university server using a VPN client. I can connect to the client. Also, if I ping the server by name and by IP address, they both work:
ping servername
ping serveripaddress
However, I cannot access the server from the browser if I type:
\servername
\serveripaddress
and also I do not see anything in Network apart from my own computer. I changed my Workgroup to the correct Workgroup, and it still doesn't work.
Also, as my DNS suffix I use the domain name as well as the FQDN, but it doesn't work either.
I restarted after each of these changes, but it didn't help.
I read that when I have a VPN connection working and I am also able to ping the server to which I want to connect, it is most probably DNS resolution problem. But I do not know anymore what to do (I checked and tried the correct DNS suffixes).
Do you know what should I do more? I am using Windows 7.
Thank you.
It sounds like you're trying to use UNC pathing. Assuming that you're getting your network settings from DHCP, are you getting a WINS server?

What address do I use to access my server from the internet?

I have an FTP server hosted on my computer and I want to make it publicly accessible.
I have forwarded the necessary ports for this specific computer on my router. If I type in my local ip, 192.168.x.x, i can access it. But this is only local. How do I access it publicly?
I tried going to my public ip but nothing comes up. I have searched Google for several hours now and have come up with nothing. What am I missing?
Test your server on https://incloak.com/ports/ or http://www.hackerwatch.org/probe/ sites and check that it detects your open FTP server. If not check you operating system firewall.

Troubles accessing the VirtualHost on a local net

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.

xampp server (How to get up and running)

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,

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.
Cheers
