VNC stands for Virtual Network Computing . It is Free set of software tools which allows you to view a computing 'desktop' environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures. It is developed by AT&T Laboratories Cambridge, presently maintained by RealVNC.
"PuTTY is a free implementation of Telnet and SSH for Win32 platforms, written and maintained primarily by Simon Tatham, who lives in Great Britain."
It is impossible and not necessary to remember all the name and IP of the server in Physics Department. You can check them here: Secure remote access to UConn Physics Computers .By default the access to this area is granted to Storrs campus Physics students, staff, and faculty. Please contact sysadmin@phys.uconn.edu if you do not have default rights but need an access to this information.
A: open PuTTY
a1, Type host name,
a2, select protocl: SSH
a3, give a name for savedsessions.
a4, save it.

C2: Type source port : 5901
C3: Type Destination : pyotr.phys.uconn.edu:5901
C4: click Add
Like this:
D: Go back to Session:
D1, save it
D2, click "open"
Like this:
E: PuTT login:
E1: type your login ID and password

7. Requirements
It will be more convenient for you to follow these rules:
a) Safely use computers in Physics
Department, like NEVER share your account with
others; ALWAYS close vncserver before you leave.
b) Run only ONE
vncserver per user
per computer.
c)
Disable
screen saver. Because since it is useless for your local machine and it
consumes up to 30% CPU of the server. (how to
disable screen saver?)
8. FAQ: Frequently Asked Questions.
1) When I
login, I got bad/strange/un-friend desktop, I can not really do anything there.
What's wrong?
You have
to edit the file .vnc/xstartup. Follow this step by step:
a) In the
putty command line, type command: vi .vnc/xstartup
NOTE: vi is an editor (command reference is
here) and do not forgot the dot "."
b) Delete
everything in the file and add two lines exactly like this:
#!/bin/sh
gnome-session &
(note: for SUSE system, please use this xstartup file
c) save and
exit. Login again with vncview and everything should be fine now.
