Hi folks,

Gentoo
Windows server 7
Windows Vista
WAN - public IP or Internet

I'm looking for a reliable solution to remote-admin
Windows server and workstation on Linux workstation. I have been running ssh for sometimes to remote-admin Linux/Unix servers on Linux workstation.

Google brought me following links;

OpenSSH for Windows
http://sshwindows.sourceforge.net/

OpenSSH on Windows v3.4-3
http://www.networksimplicity.com/openssh/

How to install OpenSSH sshd server and sftp server on a Windows
http://erdelynet.com/2004/08/30/cygwin/see-cygwincom-for-cygwin-ssh-docs/

http://pigtail.net/LRP/printsrv/cygwin-sshd.html

The project OpenSSH for Windows seems coming to a stop.

Are there any other suggestions? TIA


B.R.

there are a number of RDP clients available, any reason not to go with these?

My preferred has been

Code:

* net-misc/tsclient
     Available versions:  (~)2.0.1!t
     Homepage:            http://sourceforge.net/projects/tsclient
     Description:         GTK2 frontend for rdesktop

Hi,

Thanks for your advice.

Google brought me following links;

How To Connect To A Windows Terminal Server From Ubuntu - tsclient
http://www.watchingthenet.com/how-to-connect-to-a-windows-terminal-server-from-ubuntu.html

HOWTO Use Remote Desktop from Linux - tsclient
http://wiki.bath.ac.uk/display/Linux/HOWTO+Use+Remote+Desktop+from+Linux


Whether installing it both on Windows and Linux workstation? Windows is GUI. Whether it suports GUI? Thanks

on the windows box you're connecting TO, you simply enable RDP

if you happen to connect to a windows box from another windows box, use the built-in RDP client (start=>run, mstsc)

connecting FROM a linux box TO a windows box, use tsclient

connecting from either windows or linux, to a linux box, use ssh

and yes, RDP/terminal services, is all a GUI. It's akin to using VNC

Is "RDP" already built-in in Windows box"? Just enable it?

To install tsclient on Linux box? Will Windows screen be displayed on Linux box?


Quote:

Windows to Linux box use ssh"? Can Openssh-clients be installed on Windows"?

Thanks

Yes. Right-click on My Computer=>Properties, then go to the "Remote" tab and tick the box labeled "Allow users to connect remotely to this computer"
Administrator accounts automatically have permissions to logon via RDP. You will be prompted by Windows to enter your logon information if you don't put it into the RDP client in advance (or tsclient if connecting from Linux).

If you use Windows Firewall, you will need to make an exception for RDP.
If the Windows box you are connecting to is behind a router, you will need to go into port forwarding, and forward port 3389 to your Windows machine's internal IP (meaning, the internal IP of the box you are connecting *to*)

Code:

emerge tsclient

And yes, it will just be the windows screen displayed on the linux box; you can either do it in a window, or full screen

satimis wrote:

Yes, most notably PuTTY. PuTTY rocks.
And as mentioned above with RDP and port forwarding, same applies, you would forward port 22 to the Linux box's IP

Hi cach0rr0,

Thanks for your further advice. I'll perform a test later.

Which monitoring package shall I install on Linux workstation?

Zabbix OR Nagios OR others?

I've always used nagios, so I cannot comment on the other.
But nagios rocks.

Hi cach0rr0,


Problem solved as follows;

Windows Firewall Settings:
-> Exceptions
[check] File and Printer Sharing

Now Linux machine can ping Vista


Windows Vista
=========
Start -> Computer right click -> Properties
Remote settings starts "System Properties" window

-> Remote
Remote Assistance
[check] Allow Remote Asistance connections to this computer

Remote Desktop
[check] Allow connections from computers running any version of Remote Desktop (less secure)


Adding;

System Properties
Remote Desktop ->
Select Users ->
satimis (OFFICE-PC\satimis)

It works now with follow entries for tsclient on Linux PC;
Terminal Server Client
Computer 192.168.0.101 (LAN ip address of Windows Vista)
Protocol RDP

Vista connected on Linux machine


On router
Port forwarding
3389 192.168.0.101


WAN (public ip address) connection also works


But selecting "Allow connection only from computers running Remote Desktop with Network Level Authentication (more secure)" can't work.

How to solve this problem? Any suggestion? Thanks

Hi cach0rr0,

I have been following article;

Re:
Configure Network Level Authentication for Remote Desktop Services Connections
http://technet.microsoft.com/en-us/library/cc732713.aspx

to tweak around for several hours without result.


Thanks
