Does anyone know how to transfer a file from my vagrant VM to my host machine?
Heres what I'm trying but its not working for me - No errors but the file is not appearing:
scp -i /Users/myuser/path/mypath/.vagrant/machines/proj/virtualbox/private_key -P 2222 vagrant#127.0.0.1:/home/vagrant/database.sql
I have also tried this:
scp -P 2222 vagrant#127.0.0.1:/home/vagrant/database.sql .
And I get the error 'scp: .: not a regular file type'
Why are you trying to transfer from 127.0.0.1? That is always the IP of the machine you are currently on, so in this case the VM itself. So you are trying to do a local copy, essentially the same as cp /home/vagrant/database.sql .
You need to use an actual IP address of the host system for this to work, not 127.0.0.1 or any other of the 127.x.x.x. local loopback addresses

Introduction. My work computer (PC-B) is accessible only from inside the network (PC-A) and I can connect to PC-B via SSH in one command: ssh -J user#PC-A user#PC-B.
Problem. I need to copy folders from remote PC-B to my local drive.
I tried:
(a) from my local PC: scp -r user#PC-A user#PC-B:/path/to/folder /home/ but it does not work.
(b) while remotely connected to PC-B: scp path/to/folder userHome#PC-HOME - connection timed out.
Is there any simple solution?
You can use ProxyJump directly in the scp command:
scp -r -o 'ProxyJump user#PC-A' user#PC-B:/path/to/folder /home/
You can also create an alias in ~/.ssh/config and do not type address
of the proxy server each time:
Host PC-A-alias
User user
Hostname PC-A
Host PC-B-alias
User user
Hostname PC-B
ProxyJump PC-A-alias
Now you can just use PC-B-alias with ssh, scp and other commands that use SSH such as rsync.
I'm trying to setup a an ssh tunnel with remote port forwarding. The idea is the have a VPS act as a means to ssh into remote deployed systems (which currently incorporate a Raspberry Pi). Everything seems to work, but I run into issues when trying to move all arguments into the ~/.ssh/config file.
what does work is the setting of the HostName, User, Port and IdentityFile. However setting the RemoteForward parameter does not seem to work.
The following works:
ssh -R 5555:localhost:22 ssh-tunnel
How ever when using the following line in the config file;
Host ssh-tunnel
...
RemoteForward 5555 localhost:22
The following command returns the message "Bad remote forwarding specification 'ssh-tunnel'"
ssh -R ssh-tunnel
Obvious I found the answer almost immediately after posting the question. Using the -R flag requires you to set the remote forwarding in the command line call. However because remote forwarding is set in the config file you shouldn't add it to the command. However something confusing occurs in that aside from setting up the tunnel you also ssh into the remote server. To avoid this add the -f and the -N flag. This results in the following command:
ssh -f -N ssh-tunnel
I've deployed the Hortonworks Sandbox on VirtualBox according to https://hortonworks.com/tutorial/sandbox-deployment-and-install-guide/section/1/ .
Now, I want to ssh to the sandbox. I see this in the shell of the virtual machine:
If you zoom in on the middle of the image, you'll see this:
.
Assuming the IP-adress of the virtual machine to be http://127.0.0.1, I did the following:
$ ssh root#http://127.0.0.1 -p 8888
ssh: Could not resolve hostname http://127.0.0.1: Name or service not known
As you can see, it doesn't work. How come it is not found? I can connect through my browser by going to 127.0.0.1:8888, so clearly, there is something there. Why can't I find it with ssh?
The problem was the ip-address and the port. Changed the command to:
ssh root#127.0.0.1 -p 2222
which solved the problem.
I have read lot of post about this problem but i still can not solve it on my side.
I have a server i used to connect like this:
$ ssh user#xxx.xx.xx.xxx -p yy
user = is not root
xxx.xx.xx.xxx = ipv4 of my server
yy = custom port for ssh
Connexion works well.
I try to make a copy of a folder from my local machine (ubuntu) to the server(ubuntu 14.04) like this:
$ scp -r -p /home/user/my/folder/ ssh://user#xxx.xx.xx.xxx:yy/home/user/my/folder/on/server/
I get this error:
ssh: Could not resolve hostname ssh: Name or service not known
lost connection
I guess the connexion works well. So what could happen? A problem with rights of the folder?
For information, my local machine get both ipv4 and ipv6 address. Could it be that?
Thank you in advance for any help.

Check manual page for scp. It describe the usage of scp with all the switches and options:
scp [...] [-P port] [[user#]host1:]file1 ... [[user#]host2:]file2
Your command should be:
$ scp -r -p -P yy /home/user/my/folder/ user#xxx.xx.xx.xxx:/home/user/my/folder/on/server/
Note port comes as -P yy, you don't write ssh:// in front the user and separate host from the remote path using colon (:).
You don't need "ssh://".
Here scp believes ssh is the name of the server you want to copy to. That's what the message says : "Could not resolve hostname ssh"
Try :
$ scp -r -p -P yy /home/user/my/folder/ user#xxx.xx.xx.xxx/home/user/my/folder/on/server/
I need to do some work on a server to which I don't have direct access to. I do have access to my company network (via vpn). If I were on that network, I could access the server directly. But, for some reason when I'm on the vpn, I can't access the server directly.
So, I need to ssh into an intermediary ubuntu box, and then create an ssh tunnel from that box to the server.
Then, I can do my work on my laptop and send it through a local tunnel that points to a foreign tunnel (on my ubuntu box) that goes to the server.
But I don't know how to do a tunnel that creates another tunnel to a third server.
Any ideas?
Thanks,
Scott
What are you trying to achieve? If you just want to get to a shell on the server then ssh into the Ubuntu box and then ssh from there to the server.
If you want to access some other network resource on the server then you want to forward a port from the server (where you can't get to it) to the Ubuntu box (where you can). Take a look at the -L option in ssh.
Edit:
Copying files to the server:
tar c path/* | ssh ubuntuName 'ssh serverName "tar x"'
Copying stuff back:
ssh ubuntuName 'ssh serverName "tar c path/*"' | tar x
Obviously you need to change ubuntuName, serverName and path/* to what you want. To use rsync you need the -E option and the same trick of wrapping one ssh command inside another. After reading your comment I'd say that the most general answer to your question is that the trick is making ssh execute a command on the target machine. You do this by specifying the command as an argument after the machine name. If you use ssh as the target command for ssh to execute then you get the two-hop behaviour that you are looking for. Then it is just a matter of playing with quotes until everything is escaped correctly.
It's just a double port forward. Forward the ports from the PC to the ubuntu box, then on the ubuntu box forward those destination ports to the final endpoint. It's been a while since I've done command line ssh (been trapped in windows hell :)), so I can't give the command line you need. Another possibility is to use the SOCKS proxy ability built into SSH.
To connect from your local machine over a second machine to a specific port on the third machine you can use the ssh -N -L option:
ssh -N second_machine -L 8080:third_machine:8082
This maps the Port 8082 on the third machine to port 8080 on the local machine (eg. http://localhost:8080/ ).
