How to read a remote text file

[Ioanna Katsanou]

Hello,

I have created a SSH Client with Java that connects to a remote Windows computer.

I want to read a text file which is on the remote computer with Java and print the text. Has anyone tried this before?

Thanks
Ioanna

That depends on what kind of API this client supports. Can you easily retrieve the output of a remote command that you send? Then you could just send a type command to the remote machine.

Here's how a Linux(Unix) ssh client would do that against a remote Linux or Unix host:

ssh user@remotehost cat thefile.txt

If memory serves, Windows uses the "TYPE" command to list what's in a text file. Linux uses "cat" (it's an old joke and a cruel one), and "type" checks a file's type (not that that matters here).

However, Windows doesn't have a remote SSH server last time I remembered unless maybe PuTTY offers one as a third-party add-on. Which means that if your Java SSH app really does connect as an SSH client to a Windows computer, we need to know what on the Windows computer the Java app is talking to.

If you're really using the SSH protocol, you should checkout JSch. If you're feeling experimental you can even try my SFTP file system to use the NIO.2 framework.

Thank you everyone for your answers !!
In the end I didn't have to do this after all, but I used JSch to run a bat file on the Windows machine.
