Using SCP command to download files from Linux server to client server - linux

I'm creating files on a Linux server that I'm logged into and I'm adding the ability for the user to download these files from the Linux server on to the connecting computer. I'm writing a scrip and using the scp command to download these files:
scp data.txt user#usraddress:/home/usr
However, I don't want to specify "user#usraddress:/home/usr" to be just my computer. I want whoever is logged onto the linux server to be able do download these files. Is there a way to get the address of the connecting computer?
How would I do this?
Forgive me if this seems elementary, I'm very new to scripting.

When you open a remote session in a GNU/Linux machine, the ssh server sets the environment variable SSH_CONNECTION with some connection information. You can use this variable and the $USER variable to fill that parameters:
scp data.txt $USER#${SSH_CONNECTION%% *}:/home/$USER
Note that as far as I know you couldn't assume the client home directory is at /home. As said by chepner, you could omit the destination directory to use the default location, the home directory.
scp data.txt $USER#${SSH_CONNECTION%% *}:

access to client -machine directories while logged-in as ssh

im logged into server by ssh from macOs terminal username_on_server#server_linux:/$ but i couldnt come inside the mac client (while im logging as server user), to change directory or smthing inside client machine to send to server machine
e.g. I need to copy some file or directory from client to server as ssh but any changing directory refers to server
my-mac:~ newuser$ ssh 'username_on_server#server_linux'
username_on_server#server_linux:/home$ pwd
/home
Once you are logged into server_linux you cannot change/modify the client machine, basically the SSH connection is like if you were in the remote server. If you want to copy a file from client to server use instead scp
scp client_file username_on_server#server_linux:/server_path

SSH access parent host folder

After connecting to a remote server (A) through ssh is it possible to access host's folder/files?
This server A has access to another server (B) which I can't access from my computer. I need to run some commands on B using some config files on my computer.
I ended up copying the files from my computer to A using scp and run the commands there.

Sending .csv file from linux to windows

I want to send files (txt or csv) from linux to windows.
I already have a script to get information and put it into a .txt or .csv file, tried with many ways to send this file from linux to my computer.

scp -r fname.lname#10.10.X.X:/home/ test.txt
or
scp test.txt fname.lname#10.10.X.X:/C:/Data
Please could you help, simply I wanna have a copy of file (that I have it in server) in my computer, to use it.
there is some similar questions with no answer here.
You need a ssh server installed on windows. Windows does not currently have out of the box ssh server. They are thinking of implementing OOB ssh servers in future releases of windows 10.
Have a look at this link https://winscp.net/eng/docs/guide_windows_openssh_server
Also, if the file transfer that you want is a one time transfer, you can use putty with a reverse scp to retrieve the file or you can use WINscp ( https://winscp.net/eng/download.php )
I usually use the command 'nc' for file transmission.
But since on Windows you have to install a cygwin to use nc, so I think the simplest solution may be like the following.
On linux, go to the directory of those files, and then type:
python -m SimpleHTTPServer 1234
Then on windows you can visit 10.10.X.X:1234 in your browser, and download those files.
Note that 1234 can be replaced by any other port which is not currently used on linux.

SCP command not working - need to copy file from Windows localhost to Linux

I need to copy file admin.zip from C:\wamp\www\jdhemumbai060714\webfiles (Windows) to /var/www/html/ (Linux). I am using following command::
scp C:\wamp\www\jdhemumbai060714\webfiles\admin.zip username#hostname:/var/www/html/
But it does not work and gives error::
ssh: Could not resolve hostname C: Temporary failure in name resolution
I am logged in Linux server using SSH
I think that it is bug in SCP port.
Only way is skip "C:" and use only "\wamp\www\jdhemumbai060714\webfiles\admin.zip"
It will work if current directory is on the same disk like file for upload.
Or you can use pscp.exe
Well firstly is your DNS server able to resolve the HOSTNAME your copying too? My Advice would be to use IP Address.
scp C:\wamp\www\jdhemumbai060714\webfiles\admin.zip username#192.168.0.2:/var/www/html/
BELOW ANSWER APPLICABLE ONLY FOR EC2 OR WHICH HAS PEM KEY.
Open Windows CMD, and Type
scp -i Keypair_Along_with_Path.pem YOUR_FILENAME_ALONG_WITH_PATH.txt USERNAME#PUBLIC-IP:DESTINATION_PATH
Real Example:
scp -i C:\Users\Keypair.pem C:\Users\File.txt ubuntu#1.1.1.1:/tmp/.
You are done.

How to put a .jsp file on tomcat in Linux terminal?

I want to ask a question about the tomcat and the Linux terminal. I have a jsp file and a tomcat server. After I use the terminal to login in my Linux computer, I want to put the file to the tomcat server. However, I don't know the cmd of this action. Does anyone can help me?
P.S can also provide some basic cmd for the Linux system?
Do you mean a Remote linux terminal ? Do you use ssh ? Or you are sitting in front of it. If so, you type command "locate tomcat" it should print out the path, and then "cd path" as it was printed out. Then "cp /home/user/path/to/your/file.jsp ./"
But it's just a hint how to do that, not exact instructions. If it is on remote server, you need to run "$ ssh username#hostname.org" This way you can get to the remote server and copy the file from your home and do there whatever you want. Or the other way around. Copy jsp from your home and then ssh to the remote server
Copy the file "file.jsp" from the local host to a remote host
$ scp file.jsp username#remotehost.com:/path/to/tomcat/dir
Copy the file "file.jsp" from a your home to the linux host after you SSHed
$ scp username#remotehost.com:file.jsp /path/to/tomcat/dir
scp filename.jsp username#servername:/location-of-tomcat-servlet-root
