Practical UN*X Survival Guide

HowTo: run remote programs

One of the most important features of UN*X is the ability to run commands on remote machines. This task involves three steps, the examples assume that you are sitting in front of a machine called "local" and wish to run programs on a machine called "remote".

Allowing the remote machine to connect to your local machine:
```
	local:> xhost +remote
```
Connecting to the remote machine : there are a number of methods for this task, two of which are listed:
- telnet
```
	local:> telnet remote
```
  This will prompt for a username and password on the machine "remote" (you might be using different users and/or passwords on "local" and "remote").
- ssh (Secure Shell)
```
	local:> ssh remote 
```
  this will assume that you use the same username, but will still prompt you for a password.
Redirecting the display (csh and derivatives)
```
	remote:> setenv DISPLAY local:0
```
Please note that this command will be executed on machine "remote".

After these steps, you can run any program on machine "remote", you'll view the output on machine "local" as if you were running the program locally.
