Hello,
I've tried this, but have had no fortune.
1. This is the ip address of my centos virtual machine;
And just for the sake of it, the ip address of my ubuntu virtual machine as well;
2. My ubuntu machine can ping my centos machine;
So this shows they can ping each other and are on the same network.
3. When I try this in the address bar however, it cannot load the page;
4. The following screenshot shows OpenVZ panel being installed on centos, and it shows the url to access it on;
http://server1.example.com:3000 (this is the local host)
5. If i do the wget command on centos, it shows it's there;
6. If I try the same command in Ubuntu, it gives me this error (for both);
wget server1.example.com:3000
wget 192.168.148.129:3000
I hope I have given enough information.
I'm really determined to make this work, if you have any clues on where I'm going wrong, please advise me.
Thank you.
example.com primarily exists as documentation place holder and test ping example and is not supposed to actually be used by someone when assigning domain names to one's own computer. So if you properly configure everything you shouldn't have any problems! 
Hello Woody,
I'm not 100% sure I understand what you mean.
If you look at point number 5. in my list above, it shows that the wget command (on centos machine only) resolves to a host when you try to access; server1.example.com.
By changing server1.example.com, I'm not entirely sure how much difference this could make. Here is my /etc/hosts files on centos;
Are you suggesting I should just remove the server1.example.com part, and it should work (ie. I'll be able to access my centos localhost, via my ubuntu browser?)
localhost is just that, local to the host and when normally and properly configured as in default configurations one cannot and should not be able to communicate with localhost of one computer to another! 127.0.0.1 is after all a loopback adapter and is meant to be used internally only on each system and not beyond each system! If you want to communicate with a Service running on one system from another then you need to ensure everything is properly configured, meaning proper permission are in place and ports are open and firewalls are not blocking communications, etc.
What I will tell you is none of this is a VMware issue per se, its nothing more then a User not knowing how to properly configure and access services from one system to another. You cannot use a public registered domain name that does not belong to you or is not setup to be used for what you're attempting because as you should be able to plainly see from the output of the wget command on the system not hosting the service your trying to access it's returning a public IP Address not that of the server you're actually trying to access which has a private IP Address. Then when you use the actual IP Address and Port Number you are failing to connect because something is not properly configured even beyond the wrongly used domain name. Either the port is not open or is being blocked in some manned etc. These are not VMware issues and you need to brush up on fundamental network basics and go from there.
