I have a Virtual machine running within the Virtual Box. And now I need to access the port 25 of a IP address from the VM. The thing is I am able to do the "telnet url 25" outside the VM in my host machine, but I just can not do it within the VM, the error is "name or service not known". For the host machine, I dont have any firewalls. Any idea why
The VM can not resolve the URL cause a problem connection with the DNS server. After I replace the URL with a real IP address, it works!

Description:
There is a domain name road.songyangxing.com which resolves to 172.20.12.79. Notice that the ip is private.
We build and run openwrt on Raspberry Pi 4 Model 4. We connect the WiFi lan which the openwrt generates.
Run the command ping road.songyangxing.com, it shows Ping can't find host road.songyangxing.com.
It's OK for pinging the domain name which resolves to a public ip. It's OK for pinging road.songyangxing.com when we change another router.
Question:
How could we let openwrt allow private ip domain name?

I want access to remote cassandra with one ip address. how can I change cassandra.yaml to block all ip address except ip that I want to connect?
On current Cassandra versions there's no way to block inbound connections. You can (and you must) enable authentication, but it seems that you want to block before Auth phase.

I’m changing a server with a bare metal installation with one ip to a new cisco sever with esxi with 3 vm’s, one of them is going to be a nat router to nat the traffic to the other 2 vm’s, is there a way to keep using one just ip ?
I don’t think so, you will need at least 2 one for esxi virtual network to communicate with your network and one for your nat router vm to distribute the traffic via NAT
In fact if your server has CIMC you will need another one to have a remote access to CIMC if you need to recover the server, but it’s not mandatory because you can always connect to CIMC through the console.

I tried to ping google from both inside the container running Ubuntu and my main OS. The result is as follow:
Why is the ping from my docker faster than my main OS?
This is a known bug - ping inside container does not ping actual host ip but seems to ping localhost.
As of September 2016, it's unfixed.

ive just installed owncloud and made a "local" on my linux machine. i am trying to connect my ipad which is on the same network to it but i do not know what the server adress is?
i cannot seem to find alot of documentation on the subject so i was hoping someone here would be able to help me out?
The server is on my local machine as localhost/owncloud
Is that the adress i need to use?
because if so it says that it cannot find the server
To this kind of questions you should go to the ownCloud forums at:
http://forum.owncloud.org/
Anyway
Linux/Unix:
Type on your terminal "ifconfig" and search with interface are you using (eth0 for ethernet for example) and there is your ip
Windows:
Type on your terminal "ipconfig" and search with interface are you using. You also can go to the network options and check it.
