Hi, I need to copy some files from a server in university. I've logged in the server through my laptop. And find the folder of the file I need, but I don't know how to copy.
I've tried
scp <file> <username>@<IP address or hostname>:<Destination>
but it doesn't work. My laptop is connected wifi, is that make a different?

Are you running openssh-server on the destination machine? You need that so scp can set up an SSH tunnel. Run "sudo apt-get install openssh-server" on your machine and see if that helps.
It's also not obvious what you mean when you say you are "connected" to the remote server? Are you logged in on that machine, or do you just have access to file shares? If you are logged in on the remote, can you run a mail client (even maybe alpine)? Then you could just mail the files to yourself.
If the remote server supports SSH access, then you could try copying the files to your computer by using
Code:scp user@remote:/path/to/some/file /path/to/local/destination

Hi peng2.
I imagine that you're connecting to the server from home, so you have a router and you're behind NAT.
In this case, you would have to have resolved all issues to connect remotely from the Internet to your server at home in order to 'push' the files from the server.
Since you have remote ssh access to the server, I'd recommend 'pulling' the files from your computer.
Open a terminal, do not connect to the server, and run locally something like:
Hope it helps. Let us know how it goes.Code:scp serveruser@remoteserver:path/to/file ./
Regards.
make bzImage, not war
"I've logged in the server through my laptop."
So now you are at the server. If you want to copy from there, you got to run a SSH server on your laptop as well, which you probably won't be able to do due to a firewall somewhere.
Log out of the server. From your laptop local prompt, do scp with the full path of the file on the server.

Many thanks to you all! Problem solved.

yeah, you're right. 'pulling' files from remote server works fine. Thanks for help.

There a few ways to accomplish that. First you need a service running on your home computer. The common tools most of us use is openssh, as SeijiSensei suggested. Install it like this:
As an easy, and temporary solution, you can use a reverse ssh tunnel:Code:sudo apt-get install openssh-server
On your home machine connect to the server:
enter the password and login normally.Code:ssh -R 23456:localhost:22 serveruser@remoteserver
You have created a reverse tunnel from the server on port 23456 to your home computer's port 22 (sshd). Now you can run this on the current session on the server and 'push' the file to your home machine:
Once you have copied your file, you logout and the reverse tunnel is destroyed.Code:scp -oPort=23456 /path/to/file your_home_machine_user@localhost:
For a permanent way to access your home computer from the Internet take a look at this post here.
Hope it helps.
Regards.
