I am kinda stuck with an usual issue (or is it usual?). Let me explain.
I have two Debian VPS boxes. The first one is a pure VPN (OpenVpn) and the second one is my regular server with emails, websites and all. I also have a machine "at home" that can easily connect to these two boxes.
Now I need to connect like this: my machine at home to -> my VPS that runs VPN only and then to -> my regular VPS server.
I thought it would be easy, but I was mistaken. I allowed my VPN's static IP address through my firewall (iptables) on my regular VPS server but I didn't work. I flushed all the iptables just to see if it helps but.. it still doesn't work (it always times out, I use ssh keys to connect). I can only connect to either my VPS that runs my VPN only or to my regular VPS, but my route of home->VPN->regular VPS just doesn't work. How can I possibly do it? These two VPS boxes are working fine: My VPS with VPN is working perfectly well and my regular VPS is also working perfectly well. I would be really grateful for any pointers / suggestions / advices at all. Many thanks in advance!
Let me answer my own question. Not sure why it works this way but it works. I simply allowed "password logins" and it all started working perfectly well. It connects using ssh keys anyway without any password prompts but.. nonetheless allowing password logins in ssh solved the issue (I had it turned off earlier). Hope it will help someone too.

I've set up Strongswan VPN with StrongMan(web-interface manager) on AWS.
It works great, my company employees can access contry-restricted site without any issues. But now I need to implement split-tunneling, because we also have to send terabytes of data, daily, to non-restricted sites.
I've coded small C# app that automaticaly manages split-tunneling routes with next command.
route ADD siteIP MASK 255.255.255.255 10.10.10.1 IF VPNInterfaceID
And it doesn't work like i'd like it to work.
Problem is: my DNS are leaking in split-tunnel mode.
If i route to "www.whatismyip.com" thru VPN, it masks my IP, so it works,
but i can't access restricted sites.
So i routed "www.dnsleaktest.com" thru VPN, and i can see that my DNS are in fact leaking.
I've found an app "Simple DNSCrypt", which fixed my problem, but i really dont want to use third-party software.
I'am very new to this topic, so any help would be appreciated.
I cant figure out how to hide my DNS.
Even overriding to 8.8.8.8 and 8.8.4.4 doesnt help.
What can i do? What should i read and learn? What could be the problem?
Sorry for my poor use of English.
Thank you in advance!
I've figured it out. Maybe, this answer will help someone someday.
You have also route DNS adresses thru VPN (in my case 8.8.8.8 and 8.8.4.4),
and "disabling" default ethernet adapter DNS by setting them to 127.0.0.1.
Dont forget to revert them back after disconnecting from VPN!
I'm not sure this is even a question to be asked here, but I'll give it a shot anyway.
So I have an ubuntu server, and I recently purchased a domainname.
Now I have forwarded the domain to my IP, but whenever I reach the server, the browser shows the IP adress instead of the domain.
Is this something I should configure in Apache, or from godday (where I got the domainname)
Thanks in advance :)
Start with checking your setup at Godaddy. What you probably need is an A entry.
The good news is that your setup seems to work since you get an answer from you server!
Perhaps this can help

I am a noob when it comes to network. Recently, I was trying to help a friend edit php code. In his office, there is a computer running which he said is the server that hosts the site. But he is not sure since the guy that build the site is unreachable now. So, he gave me the password and username to this local server but no ip to me. I have no idea how to connect to this "in house" server.
I see that there are several computers in the office and I tried to ssh to their LAN ip, ie. 1.1.1.1... to 1.1.1.10 something like that but none of the connection went through.
When I look up the ip of the website and put the ip into the browser, it actually goes to networksolutions.com. So guys, do you think the source code can be found on networksolutions.com(which is what I think) or is there a way to try to connect to this "in house" server(I am not even sure whether there's anything in it).
Have you tried attaching a monitor and keyboard to this server to determine what it is?
The IP of the site appears to be virtual hosted by Network Solutions. It is likely the server in the room is in fact not the server, instead that is handled by NetSol.
if you know the local ip range of the network which is normally either 10.*.*.* or 192.168.*.* or so you can use nmap to locate any servers quite quickly like: nmap -vvv 192.168.0.* which takes 5 seconds to find 4 end points
I am trying out a conferencing application (BigBlueButton).
For this I created an Ubuntu virtual machine that functions as the application server. On this machine I can test the application by navigating to the app url (for example http://10.0.2.15).
I also created a second virtual machine that should function as a client. On this machine I want to be able to navigate to the server as well, but that doesn't seem to be working. If I try to navigate from the client to the server by using the app-url I get nothing, followed by a timeout.
To establish a network between the two machines I tried the following solutions:
Create a second network adapter on each virtual machine and attach to "Host-only Adapter" with name "vboxnet0"
Create a second adapter on each machine and attach to "Internal network" named "intnet".
I thought that either of above options would be a good solutions, but none of them works.
Can anyone help me out here?
FYI I am using MacOS X as host system.
EDIT:
I created my second machine by cloning the first one (using the clone utility). Maybe this causes both machines to be identical which makes them indistinguishable on a network. Would this cause a problem? (As a desktop developer I'm a bit of a noob when it comes to I.T.)
I just got this to work. What I did was the internal network with the tasteful name on both VMs, but THEN I went to Advanced and set the Promiscuous Mode to "Allow All". I connect just fine now. Try it!
OK, just looked at the dates and it was last updated 2009, but for anyone looking for the answer, here you go!
IF you cloned the machine and didn't change the ip, they will never connect...
Also - make sure there is something listening on the url that you're trying to reach.
each machine should have a different ip
(but on the same network of-course)
Set the interfaces you created to internal networking. Choose a tasteful and interesting name, like "mynet". Use that name as the network name for both of the virtual machines and they will automatically be able to talk to each other over those interfaces.
Sorry, I see you already did that. In this case just give those two machines static IP addresses on the interfaces of "internal networking" type. Like, 192.168.0.2 and 192.168.0.3.
Also, once you've changed the IPs make sure the server is listening on the right interface.
I realize this is long overdue... But I just got mine set up and am able to ping each virtual machine from one another.
Assuming you're running boot2docker like I am, simply right-click the boot2docker VM in VirtualBox and click clone. In the box that pops up, be sure to check the box that says "Reinitialize the MAC address of all network cards" so that the two virtual machines don't have the same MAC address.
That's it, seems to be working for me. I can ping, scan (via nmap) and even SSH into the virtual machines from one another or from my host machine.
I have tried to access a website that i created in my xp machine that have iis 5.1 from the LAN , but without any success i have tried what is suggested in the following link How to access your website through LAN in ASP.NET , but also without any clue . I open my site in my PC(locally) like this "192.168.1.252/pse" and it works , but from other pc in the LAN , its not displayed at all.
Any Help will be most appreciated.
Thanks,
Saed
Is your Windows Firewall turned on?
You say, "its not displayed at all". What happens instead of it being displayed? Is there an error message?
Most likely, your firewall software is blocking external access. If external users can find your machine using ping, then that suggests a firewall is blocking access.
Please do what the two previous posts suggested, check to see if you can ping your computer from a different computer within the network and then check your firewall also.
When you are done checking the above suggestions, if you still have trouble viewing your page from a different computer, check to see if your computer has port 80 open. And if it is using port 80 and everything looks ok, please provide the error number you are receveiving, I am guessing it is 404 - Page not found.
Hope this helps!
It was firewall and Antivirus problem , they were blocking the port 80.
Thanks All for your Help.
