Remote Logins to prime

Remote Logins to `prime`

When you are not in the lab, you can still log in to do some work on your account. You won't be able use the BlueJ program remotely, but you can edit files using an editor like pico or emacs. You can't log onto prime directly, but you can log onto p1.cs.ohiou.edu or p2.cs.ohiou.edu.

This is what CNS suggests for Vista users: link. Please try it and let me know how it works.

You can log onto p1.cs.ohiou.edu via some SSH program, like oak SSH or Putty

Note for Oak SSH users (dorm computers):

change the host to p1.cs.ohiou.edu
change Authentication Method to Keyboard Interactive

From any UNIX like machine, (Linux/BSD/Os X) type:

    ssh -l loginid p1.cs.ohiou.edu

from the command line, where loginid is your prime login. For Linux users, add -X to the comand line arguments and you can work as if you were on the machines in the lab. For Mac Os X users, do the same from an X11 terminal window but add -Y to the command line arguments. It isn't quite as seamless as with Linux, but it works well for some things. You can run firefox, for example.

If you work on programs at home, here are some ways to copy files and/or directories to and from prime:

Windows users using OakSSH can open up a New File Transfer Window by clicking on the folder icon after logging onto p1. From there, you can drag and drop either directories or files in either direction.

Another choice for Windows users is to use WinSCP to copy files to and from your machine at home.

Mac users can either use scp from the command line or download fugu, which allows file transfer. Since it doesn't yet do SFTP for folders (as directories are usually called in the Mac OS) in both directions, it will ask for you to type your password again if you decide to copy whole folders from p1 to your home computer to open up SCP. This is fine, just type it again. If you use fugu, you can ignore the port and directory text boxes and navigate using the GUI if you'd prefer. Another Mac option is to use CyberDuck SFTP to copy files back and forth from p1.cs.ohiou.edu

Linux or BSD users and some Mac users are probably ready to use the command line to transfer things, so they are advised to type:
```
    man scp
```
for information about copying files and directories from machine to machine. Talk to me if you need help.

There may be nicer programs out there. If you find some, let me know. I have very little recent experience with the windows environment, so I'd be obliged if somebody sends me a link to resources telling how to "tunnel in". A few years ago there was such a PC program that had serious security problems.

Note: With some SSH programs, opening emacs can cause problems, since the computer will try to open up the full screen version of the editor. If you run into this problem, type

    emacs -nw fileName.extension

and it won't try to start up the XWindows version. This can be a problem with Putty and in some other situations.
