I try to transfer files from remote computer using ssh to my computer : scp My_file.txt user_id@server:/HomeThis should put My_file.txt in the home folder on my own computer, right? I get scp/Home: permission deniedAlso when I try: ...@server:/Desktop, in order to copy the files from the remote computer to my desktop. What am I doing wrong? 
Transfer files using scp: permission denied
ssh;permissions;scp
Your commands are trying to put the new Document to the root (/) of your machine. What you want to do is to transfer them to your home directory (since you have no permissions to write to /). If path to your home is something like /home/erez try the following:scp My_file.txt user_id@server:/home/erez/You can substitute the path to your home directory with the shortcut ~/, so the following will have the same effect:scp My_file.txt user_id@server:~/You can even leave out the path altogether on the remote side; this means your home directory.scp My_file.txt user_id@server:That is, to copy the file to your desktop you might want to transfer it to /home/erez/Desktop/:scp My_file.txt user_id@server:/home/erez/Desktop/or using the shortcut:scp My_file.txt user_id@server:~/Desktop/or using a relative path on the remote side, which is interpreted relative to your home directory:scp My_file.txt user_id@server:Desktop/Edit:As @ckhan already mentioned, you also have to swap the arguments, it has to be scp FROM TOSo if you want to copy the file My_file.txt from the server user_id@server to your desktop you should try the following:scp user_id@server:/path/to/My_file.txt ~/Desktop/If the file My_file.txt is located in your home directory on the server you may again use the shortcut:scp user_id@server:~/My_file.txt ~/Desktop/
