remote login to Linux

I heard about NX
http://www.nomachine.com/download.php

which one do I need to install on Linux box ??

I believe I need "NX Client for Windows" on windows box.

The usual way of logging in to a remote server is simply SSH via Putty: http://www.chiark.greenend.org.uk/~sgtatham/putty/ and WinSCP: http://winscp.net/eng/index.php

NX is used if you want a remote desktop connection - which makes things a lot more complicated than simply administering on the command line.

You will then need to install the NX server on the host server (which will emulate a desktop environment which servers usually don't have), and the NX Client on the machine that you use for establishing a connection.

well actually I am trying to remote desktop to linux.

I installed the NX Server in Linux under  /use/NX and installed it correctly.

When I try to connect to linux from my Windows Box, the NX client on windows fails" not sure what this means

NX> 203 NXSSH running with pid: 5704
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
NX> 285 Setting the preferred NX options
NX> 200 Connected to address: <linux IP address> on port: 22

nxserver: error while loading shared libraries: /usr/NX/lib/perl/IO.so: cannot open shared object file: No such file or directory
NX> 280 Exiting on signal: 15

i installed the NX Node also on Linux as per
http://www.nomachine.com/download-package.php?Prod_Id=1980

but this it failed with

NX> 203 NXSSH running with pid: 704
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
NX> 285 Setting the preferred NX options
NX> 200 Connected to address: <linux IP address> on port: 22

NX> 595 ERROR: Detected an inconsistency in the NX server configuration.

NX> 595 ERROR: (usually '/var/log/messages').
NX> 280 Exiting on signal: 15

I looke at the log file and it seems like
/usr/NX/bin/nxssh is not present.

Where do I get this from?

looks like I am getting closer. I instaled the NX client also on Linux.
this time it failed saying  "Use root cannot be used as an NX user"

not sure why?

Try installing the NX client on the server as well.
In essence, follow the instructions as given here, under "Setup remote desktop through NX": http://www.benmccann.com/dev-blog/opensuse-111-installation-and-setup/
