For me, networks are a very "opaque" thing, and even with reading a lot of tutorial about SSH, I do not understand how to create a basic tunnel to transfer my files.
The configuration is the following :
My Computer --[Internet]--> Bridge Machine --[Local Network]--> Final Machine
Currently I do the following :
1) Connect to the Bridge Machine with :
ssh -X
[email protected].
fr
2) Connect to the Final Machine with :
ssh -X username@finalmachine
3) I copy the address of files I need (for example .../mydirectory)
4) Then I deconnect from the finalmachine with :
exit
5) I copy the files to the bridge :
scp -r username@finalmachine:/.../mydirectory .
6) I deconnect from the bridge with :
exit
7) I copy the files to my machine :
scp -r
[email protected]:/.../mydirectory .
Which is quite complicated. My question is basic : how to simplify this using a SSH tunnel ?
(and please explain me the signification of each command line you write, to understand what each line really do and to avoid to use it like a magical thing. Furthermore if some ports number are used, explain me if I can pick a completely random number or if I have to choose a specific one.)
