1.5 Manuals and Consultants:
On any UNIX system, to get information about a command (e.g. ssh) try to type ``man ssh''. If the manual page is not on PHELAFEL try it on TX/T2. Different software packages have their help files in different places, but, in general, lots of good information and help for Technion graduate students with computing matters related to their RESEARCH can be found from the Technion Computer Center consultants. Information about software packages for both this course and your thesis research can be found from the Technion Computer Center consultants. Riva has prepared some really good manuals and pages for Physics students, see the the general computer site and select unix/linux and then guides
1.6 The Web:
an introduction to the web and some websites that are relevant to this course. On many systems you iniate the browser from an icon, but if you wish to use a different one you may e.g. use the command firefox & to iniate e.g. firefox. The & ( ampersand) means that the job runs in the background. For later in the course you will need to prepare your own homepage, to be listed on the class website list.
1.7 Security Issues:
precautions to avoid being hacked and how you can help us keep PHELAFEL hacker free. ``ssh'' is the main command to remember
ssh (Secure Shell) a program for logging into a remote machine and for executing commands in a remote machine. It is intended to replace rlogin and rsh, and provide secure encrypted communications between two untrusted hosts over an insecure network. X11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel. If your account names differ then use ssh -l nameonphelafel to enter phelafel.
scp (Secure Copy) copies files between hosts on a network. It uses ssh for data transfer, and uses the same authentication and provides the same security as ssh. Any file name may contain a host and user specification to indicate that the file is to be copied to/from that host. Copies between two remote hosts are permitted.
to copy a file called file1 from phelafel to tx (to your account of the same name) write scp file1 tx:
A version of ssh for PC computers can be found at the PuTTY site .
