Converting to encrypted communicationprograms
Some programs use insecure protocols (they transmit everthing, passwords
included, uncoded through the network, making it possible for anyone to
intercept):
-
ftp
-
telnet
-
Some mail programs
Therefore these possibilities will be disabled in the (near?) future. This
page is meant to provide some alternatives which will hopefully restore
the ability to log in from practically everywhere.
Logging in
telnet will in general be replaced by ssh. On Linux/Unix
machines this means that in stead of typing
"telnet pool9.math.uni-bonn.de"
you need to type
"ssh -l [your login] pool9.math.uni-bonn.de".
For Windows computers, two wide-spread programs which allow the use of
ssh are Terra Term and PuTTY. Mostly they can be found somewhere
on the desktop or in the start menu. If you cannot find them or a similar
program, you can download PuTTY here:
Download putty.exe (by pressing
the Shift-button) and save it onto the desktop (by choosing Desktop in
the "Save As" window). No further installment is needed. Just go to the
desktop and start PuTTY (doubleclick). You will then be prompted for a
Host name and a Protocol (where you can select ssh).
Clicking on Open will start your session.
On a permanent (home) installation of PuTTY you can save your host name
and protocol. To do this you need to provide a name in the window Stored
Sessions and Save it.
For Macs there is Nifty or
Macssh (68k or PPC).
But by lack of a Macintosh I can give no description how they work. Information
can be found at http://www.pure-mac.com/telnet.html
Copying files
To copy files in a secure way from a Windows computer there are two ways
(on this page). If you prefer an MS-DOS based program use
pscp.exe.
Download it and save it in "C:\windows". Then start an MS-DOS prompt and
go to wherever your working directory is. To copy a file, say "happy_song.txt",
to your account you type the command:
"pscp happy_song.txt [login]@pool9.math.uni-bonn.de".
Another way is WinSCP (form the creator of PuTTY).
Installation is similar to the installation of PuTTY.
