SSH and SCP help

rated 0 times [ 1] [ 0] / answers: 1 / hits: 1689 / 2 Years ago, wed, december 8, 2021, 11:49:35

I'm a university student, and very new to ssh and scp... and new to programming. The newest assignment given to us requires accessing libraries that are only on the student server at university. To work at home, they said to use SSH.

So I've done that, and I can use ssh to log on to the student server, so that I can compile using the libraries stored there (C++ programming)

However, I'm not sure how to do either:

compile the files on my local computer in the student log-in terminal. OR

use scp to copy the files I'm working on to my @student folder, so that I can then compile while logged in.

with regards to b) I've tried the following command:

scp mike@ubuntu: /a1644923/testscp [email protected]: a1644923

but then I get:

ssh: connect to host ubuntu port 22: Connection refused

cp: cannot stat `/a1644923/testscp': No such file or directory

The sensible thing to do is to copy the files from your home computer to the student server. (What you tried in the second step)

scp requires two parameters: source and destination, and only the remote part needs username@hostname.

So your command (for one file for testing) should read:

scp a1644923/testscp [email protected]:

The colon at the end is important. Make sure to have no extra blanks in the command. I assume the directory a1644923 is in your current directory. You can copy/paste that command into your shell.

If you need to transfer a complete directory instead you must enable recursive mode. I am assuming you have a directory project1 in your current directory. So type

scp -r project1/ [email protected]:

Mind the blank between scp and -r. The command is scp and -r is a parameter, telling scp to work recursively, i.e. to copy everything below.
