WinSCP screws up line breaks in files – how do avoid

Use a SOCKS proxy.

The source port is now (locally) a SOCKS proxy. Configure FileZilla to use it as a SOCKS proxy (see below). It'll open a connection through that to the host you ssh to (your work machine) and then connect from there, to any IP address you give it. Works for anything with supports SOCKS and that includes FTP.

The rest of the PuTTY config just remains the same - configure the ports (as shown) and then connect that PuTTY session to your Work machine via SSH.

Here's what the FileZilla option needs to look like,

When you put in the target for the FTP connection, use the IP address not the hostname, because DNS resolution may still happen locally and you don't want that.

The whole thing is secure and invisible - it looks like a basic SSH connection to anything else on the network.

NB: If you want to do this from the command line, you can use PuTTY's plink.exe to do the following,

plink -ssh -D 9090 you@your.work.laptop.example

it achieves the same thing without having to create a PuTTY profile or use the GUI.

I'm going to assume you can already sudo to the user in question ... ... in WinSCP setup for a new site:

1. New Site
2. Session: File protocol: SCP
3. Session: host name: my-host-name
4. Session: user name: MY-user-name
5. CLICK Advanced... BUTTON
6. Advanced: left-hand-navigator select SCP/Shell

7. Advanced:Shell: MAGIC-HAPPENS-HERE The "pick list" for Shell has "Default" selected. You will enter TEXT here...

   /usr/bin/sudo -u TARGET-user-name -i

(above command varies by unix distro)

8. NO-OTHER-CHANGES to the default settings, just select OK to close the Advanced window and save your changes.

..... this should be all you need!
