SSH and Slogin
Secure Shell and Secure Login are the same thing. They're
programs that allow you to log in to your system through an encrypted
connection. This is a good thing because when you log in remotely from
someplace other than the console, your connection gets bounced along
multiple computers. Specifically, your password gets bounced along
multiple computers, and it's not encrypted!
Granted, finding a computer that allows an SSH login from it is a pain in
the neck, but it's worth it. Having a user's password sniffed is very
uncomfortable, and having the root password sniffed is dangerous.
It is worth the effort of installing this program.
To obtain it, go to this web site: ftp://sunsite.unc.edu/pub/packages/security/ssh/.
The ssh-1.2.26.tar.gz file is the latest SSH program that is not
subject to stringent licensing agreements; this is the file that is
documented below. The agreement on the later versions of SSH requires
that the software be purchased unless it is only to be used for
educational purposes. Download the file.
Make yourself root.
Put the downloaded file into the /tmp directory.
Type gunzip ssh-1.2.26.tar.gz and wait. Upon regaining the #
prompt, type tar -xvf ssh-1.2.26.tar and the files will
The # prompt will come back up.
And that's all there is to it. From now on,to connect to
another secure site the command slogin -l [username] where
username is the username of the other account will bring up a prompt
for a password. If the password is correctly entered, the two servers
will set up an encrypted, secure transmission.
- cd ssh-1.2.26
- pico README
- Follow the instructions contained there. They contain all the
instructions on how to correctly install SSH.
- cd /tmp and then
rm -rf ssh-1.2.26 (Remove [recursive] [force] command) This will
get rid of the directory in the /tmp file.
- To enable the ssh daemon to allow other people to connect
securely to the machine, cd /usr/local/sbin/
- Exit root.
Anyone coming in from the outside will be doing the same thing.
