Connection timeout error for winscp to cloudera vm - windows

I am trying to connect Cloudera VM from my Windows desktop using Winscp for file transfer.
But I am not able to connect it using winscp. It is showing me connection timeout error.
Anybody has any idea how to solve this issue.
Thanks,
Atul

I figure out, bow to do it. The error was I am referring wrong IP address. To know right IP address and connect follow below steps.
First, if the Cloudera VM is running then shutdown it.
Second, go to setting. refer below screenshots
Then start the Cloudera VM again.
Go to terminal.
Type the command ifconfig.
On Consol you will find eth1 - where you have to look for ipnet, next to it is your IP address, which you have to use to connect to VM. note down the address.
Go to windows.
Open Winscp.
Create New Site.
Put the host name as the IP address which we got from consol
Username- cloudera, password- cloudera
Port-22
Click on Save.
Click on login.
Hope this will help.
Thanks,

I can connect to cloudera VM 5.15 from winSCP from my laptop(windows).
I am using Virtual box.
I have downloaded VM from cloudera official site and then choose option file-import appliance ,it will choose by default Network adapter NAT and then I followed as mentioned below.
add cloudera.quickstart in hosts file
C:\Windows\System32\drivers\etc\hosts
localhost name resolution is handled within DNS itself.
127.0.0.1 localhost quickstart.cloudera
Recommended VirtualBox Configurations
Right click on the VirtualMachine and click Settings
Setup the VM to allow you to copy and paste from that machine to your local and vice-teversa
Click on General -> Advanced
Set Shared Clipboard to Bidirectional
Setup port forwarding from port 2222 to port 22 to allow SSH to the machine
Click on Network -> Advanced -> Port Forwarding
Add a new entry
Name: 2222
Host Port: 2222
Guest Port: 22
Accessing the VM
SSH’ing to the Machine
Default SSH Credentials: cloudera/cloudera
Host to connect to: localhost
Because of the Recommended VirtualBox Configuration above, we’re forwarding connections from port 2222 to 22. So you would want to use port 2222 to connect.
Windows
Open putty/winscp
Use ip as 127.0.0.1
Set 2222 as the port
Connection Type: SSH
Click open
Enter the password

Why can't I connect to 127.0.0.1 HortonWorks Dashboard?

I have installed Virtual Box (Version 5.2.0 r118431 (Qt5.6.2)) on Windows 10 and i imported appliance HDP_2.4_virtualbox_v3 (downloaded from here).
I followed the tutorial from here step by step.
The virtual machine is running on the computer from where I am trying to access the Dashboard. I have set up the Host Only Adapter Option on the sandbox so the computer and the virtual machine can communicate
After the CentOs finished booting I am prompt to enter to the ip 127.0.0.1:8888, which is a different address from the tutorial,
and there is no server listening to that address because i get
"127.0.0.1 refused to connect." in the browser.

Run the ipconfig command in your command prompt and identyfy your virtual box's ip under Ethernet adapter VirtualBox Host-Only Network.
Take that ip address and go to your Virtual Box.
Select your appliance and go to Settings->Network->Adapter 1->Port Forwarding.
Replace the Host IP 127.0.0.1 for the port you need 8080, 8888 and so on with the ip of your virtual box that should be sth like 192.168.x.x.
Now start your sandbox, login on it and try to connect in your browser to the new ip set 192.168.x.x:8888.
Use appliance HDP_2.4_virtualbox because in the most recent some linux commands like netstat are considered deprecated and no longer function, which willmake your life harder when trying to debug or identify a networking problem.
If you still encounter issues eith it, reinstall your operating system, reinstall your virtual box and reimport the sandbox, make the changes needed in the Port Forwarding settings and it should be ok.
try to connect using 127.0.0.1 to connect make sure the VM is running make sure there are no errors if there are debug them and at the last straw uninstall the Vm and retry (make sure to make a backup if there are any files)
you can also try to check all the local host ips on your network and try to connect to them
Make sure you set NAT in your VirtualBox network settings:

Docker Toolbox - Localhost not working

So I'm using Docker Toolbox because I don't have Hyper-V on my machine since it's not Windows 10 pro. Everything seems to work fine, but when I try to go on my browser 0.0.0.0:80 it always returns me: This site can’t be reached
But when I run the command: docker container ps I get the following: 0.0.0.0:80->80/tcp meaning that this address should work. I searched across stackoverflow and github issues. Now I'm stuck.
Am I missing something?
Thanks,
Mark
EDIT:
Using docker-machine ip default returns me 192.168.99.100. I run that on port 80. I still get the same result except that the address becomes the container id: https://fd677edg12
I run that command on cmd to find my ipv4: cmd /k ipconfig /all. Put the result with the port and it returns the same thing: https://fd677edg12
Docker Toolbox doesn't get as many conveniences as Docker for Windows, but you're correct in using it since you're on Home edition.
In Toolbox, nothing will be localhost, and will be 192.168.99.100 by default, since it's running a Linux VM in VirtualBox.
So if you run docker run -p 80:80 nginx
(notice I had to publish a port for 192.168.99.100 to listen on that port)
Then going to http://192.168.99.100 should work.
I initially had a few issues with accessing my Applications at localhost:8080 while using DockerToolBox and OracleVM VirtualBox.
In VirtualBox:
Click the appropriate machine (probably the one labeled "default")
Settings
Network > Adapter 1 > Advanced > Port Forwarding
Click "+" to add a new Rule
Set Host Port 8080 & Guest Port 8080; be sure to leave Host IP and Guest IP empty
Run the command:
docker run -p 8080:8080 ${image_id}
I was following docker for windows tutorial in https://docs.docker.com/docker-for-windows/#set-up-tab-completion-in-powershell and got stuck in step #6 when test nginx in the web browser. Seems I faced a similar problem since I also use Windows Home and don't have Hyper-V. My workaround is quite simple:
check your docker IP default
$ docker-machine ip default
192.168.99.100
Go to Oracle Virtual Machine to set for port forwarding. Make sure the network setting is NAT, and add port forwarding.
Host IP: 127.0.0.1, Guest IP: 192.168.99.100, port all set to 80
like this
Try again to your browser and run http://localhost or http://127.0.0.1 (can add the port 80 also). It should run.
The thing is that the nginx IP is meant to be accessible within the docker Virtual Machine, so that we need that port forwading setting in order to access it directly in the host machine's browser
You can use localhost instead of '192.168.99.100' by following the instructions:
Step #01:
docker-machine ip default
You will see the default IP
Step #02:
docker-machine stop default
Step #03:
Open VirtualBox Manager (from the start programs in windows search for VirtualBox Manager)
Select your Docker Machine VirtualBox image (e.g.: default)
Open Settings -> Network -> Advanced -> Port Forwarding
Add your app name, the desired host port and your guest port
i.e, app name : nginx, host: 127.0.0.1, host port: 80, guest port: 80
Step #04:
Now you’re ready to start your Docker Machine by executing the following:
docker-machine start default
Then just start your Docker container and you will be able to access it via localhost.
Have a look here for details.
To map the ports expected to localhost instead of hitting the docker-machine IP directly, you can use the VirtualBox CLI.
If the docker-machine VM (here called default) is running, add and delete rules like this:
> VBoxManage.exe controlvm "default" natpf1 "nginx,tcp,,8888,,8888"
> VBoxManage.exe controlvm "default" natpf1 delete nginx
If the VM is not running, or you want to stop before altering it:
> docker-machine stop
> VBoxManage.exe modifyvm "default" --natpf1 "nginx,tcp,,8888,,8888"
> VBoxManage.exe modifyvm "default" --natpf1 delete "nginx"
> docker-machine start
Where the format of the port forwarding rule is [<name>],tcp|udp,[<hostip>],<hostport>,[<guestip>], <guestport>.
Note that in VirtualBox, you want to map to the host port of Docker map, not the internal container port. You're mapping host -> VM, then Docker maps VM -> container.
See the VirtualBox docs.
This is another easy way to avoid typing the ip 192.168.99.100.
Go to C:\Windows\System32\drivers\etc\hosts and add at the end of the file:
192.168.99.100 docker.awesome or any name of your liking.
Save the file (You need to have admin rights so make sure you right click on the file and run as administrator to be able to save it when you edit it).
Go to your chosen domain name, docker.awesome:8080 in this case and there you have it.
After lot of trials, I was able to get this bulletin board.
The docker run command I used - docker run -p 4680:8080 --name bb bulletinboard:1.0
Here, 4680 is localhost port number.
8080 is container port number, the port at which the container will be listening. This port number is mentioned in the EXPOSE command in the Dockerfile.
Then, go to web-browser and type 192.168.99.100:4680
Here, 192.168.99.100 is the docker machine IP address (use command -> docker-machine ip)
After this, your browser page should open to -
Hope this helps you all!!

How to bind the VM docker-machine creates to OSX IP address?

I'm developing locally with Docker on OSX using the latest Docker toolkit. I have a node server running in a docker container, bound to port 9999 of the VM. I can hit this server from a browser on my mac, and I would like to hit from another device on the same network. Is there a way to bind the VM to the machine's IP address? Or otherwise expose it?
I just figured this one out today! I am using docker-machine with virtualbox on Mac OS 10.10.5. The first thing I tried was to change the network interface from NAT to Bridged. This just breaks docker-machine's ability to communicate with the VM.
Instead I ADDED another network adapter running in bridged mode.
After starting the docker-machine I get this:
$ docker-machine ip redis-test
10.222.11.242
That is a local network address accessible from anyone else in my office or on my VPN.
Then if I run something like:
$ docker run -p 6379:6379 -d redis
I get a containerized redis service running on port 6379 of the 10.222.11.242 address.
So I can do this from anywhere else on the network:
$ telnet 10.222.11.242 6379
Trying 10.222.11.242...
Connected to 10.222.11.242.
Escape character is '^]'.
info
$1827
# Server
redis_version:2.8.19
...
And as a cool bonus of this we can remap the ports like this:
$ docker run -p 8080:6379 -d redis
e7cc53d9c157a658041c3bee5967dd3678b4d35e6146a02220a87bfebfc919ad
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e7cc53d9c157 redis "/entrypoint.sh redis" 7 seconds ago Up 6 seconds 0.0.0.0:8080->6379/tcp goofy_yonath
bf1dc6c7c6b5 redis "/entrypoint.sh redis" 51 minutes ago Up 51 minutes 0.0.0.0:6379->6379/tcp redis
Now I have two redis instances listening on different ports (6379 and 8080) of the same IP.
EDIT: Here are some details to help those confused about adding a NIC to the VM in VirtualBox. I have only used VirtualBox for this and cannot advise about other virtualization system configurations.
Stop the VM by selecting it in the VM Manager and using the right-click menu or pressing 'command-F'.
Click "Settings".
Click "Network".
Select one of the Adapters that is not currently enabled.
Enable it.
Select "Bridged Adapter" in the "Attached to" selection.
Click OK.
Start your VM and try it out.
NOTE: I am sure there are some clever command line options for doing this setup, but since I only ever needed to set it once I have never bothered to automate it.
You could setup port forwarding on the VirtualBox NAT adaptor.
Bridging it to the local network (in the answer above) is not the same as using the OSX IP address. Bridging can sometimes cause extra headaches if you are on laptop and move to different internet connections. The VM may not automatically pull a new IP from the new network, etc.
In the UI go to Settings --> Network --> Port Forwarding or from the commandline something like this:
VBoxManage controlvm "default" natpf1 "tcp-port9999,tcp,,9999,,9999";
where "default" is the name of the VM ("default" is normally used for docker-machine) and 9999 is the port you want to map.
More info at: https://github.com/boot2docker/boot2docker/blob/master/doc/WORKAROUNDS.md
https://www.virtualbox.org/manual/ch06.html (Configuring Port forwarding with NAT)
Did you put the expose command in Dockerfile?
EXPOSE 9999
Based on #e.thompsy answer, here is the command line version.
First, figure out the interface name you need using:
vboxmanage list bridgedifs
For me it was en1.
Then:
docker-machine create ...
docker-machine stop $VM
vboxmanage modifyvm "$VM" --nic3 bridged --bridgeadapter3 en1
docker-machine start $VM

How to use Putty to connect to a virtual machine?

I am running a virtual machine on Virtual Box
On running ifconfig eth1, I get
inet addr: 192.168.56.11 and many more values.
How do I use Putty (ssh) here?
I entered 192.168.56.11 on the Host Name and 80 on the Port Number, but Putty can't connect.
I am trying to follow the guidelines from this course:
https://s3-us-west-2.amazonaws.com/cs144-misc/instructions/vm.html
What exactly does Putty do? I don't understand why I need to do this.
PuTTY will open a "network" between both machines. You'll get a console (like the shell) when you'll be connected. Really useful to administrate remote server from your computer.
Usually, the port is not 80, but 22.
For oracle vm virtual box:
1)Power of your machine
2)goto Settings -> Network -> Adapter1 -> Enable Network Adapter -> select "Bridge Adapter" in Attache To tab and click 'ok" button
3) open terminal in virtual box and type" ifconfig"
in first paragraph
eth0 Link encap:Ethernet HWaddr 08:00:27:fb:d1:28
inet addr:172.16.2.199
4) Here ip address is "172.16.2.199" using this ip and port 22 ,you can login through putty and winscp also
Try opening terminal through VMWare's console on Ubuntu and then run below given code:
sudo apt-get install openssh-server
I had faced the same issue.
Note: I assume you have already started the VM, importing the ISO image, and tried to access the machine with 10.X.X.X or 172.X.X.X range IP address from the Putty agent and got an time-out message.
Before making any changes to the network configuration on the VM or trying bridge-adapters, as suggested by many of the articles online, I suggest you to check 2 robust points which forms the bus for your VM on VirtualBox and Putty agent installed on your system.
1st Point:
Opening Host Network Manager in File section of your Oracle VirtualBox
Adding a host-only ethernet network (I suggest to keep a 192.X.X.X range)
2nd Point: Adding a host-only adapter, under the network settings of your VM.
Host-Only Adapter settings
If you follow these steps before booting up the VM for the first time, your VM will be allocated with a 192 range IP address (by the dhcp) the moment it boots up and starts running. Now all you need to do is, install and openssh-server and use the 192-range IP address with the Putty agent and Voila!!
Hope this help! Greetings!

cannot connect to host 127.0.0.1 Virtualbox

So I'm using a Macbook Pro with virtualbox and trying to SSH to CentOS virtual machine.
I've started the SSH service on centOS and I've gone into the network settings of virtualbox and made sure that the adaptor was set to NAT and that port forwarding was set to port 22 for the guest and host.
When I run the following on my mac: ssh 127.0.0.1
It says: ssh: connect to host 127.0.0.1 port 22: Connection refused
Any ideas why?
Fixed the issue by enabling ssh on mac. I didn't realize it was off as default! If you go into the sharing options in system preferences you can tick a box which enables ssh. To connect you must use: $ ssh username#192.168.1.111 (or whatever the ip is of the machine).
