Putty terminal
Linux terminal services. Putty terminal (for Windows) understands minion tasks such as host verification, data encryption, virtual terminal network tunneling and X11 port forwarding! The ssh server running in Linux offers all the above plus the security model that all Unix-inspired operating systems adopt!
Samba server
File server: With the help of the terminal we configure Samba in Linux. SMB is widely known as the Microsoft File and Printer Sharing protocol. Samba also serves the Netbios protocol.
Putty as a serial terminal Putty as a Dumb Terminal. By interconnecting the server's - client's serial ports we can communicate old style. The dumb terminal can also be an old pc with a tiny linux custom installation, an old Windows 3.x machine or even a DOS installation - or just a bootdisk with serial/modem clients like Telix.
WinSCP for Windows and SSH server in Linux
Aside from terminal and remote command, SSH in my Linux server also supports secure copy with host verification and data encryption. WinSCP for Windows here uses the Norton Commander style. Explorer style (i.e. 1 panel) is also available. Each style has its own keyboard shortcuts, Commander option using the traditional Norton ones i.e. F5 for copy etc.
Sql server in Linux
                and frontend in Windows Making the database backbone: MySQL in the Linux server is tested by the HeidiSQL frontend in the Windows client. After ODBC configuration, MS Office and Openoffice.org take off client/server style. MLDonkey backend Sancho frontend
Organizing a peer2peer backend in the linux server: MLDonkey is edonkey2000 and bittorrent compatible. Sancho is an MLDonkey frontend for Windows. Frontends on several computers can connect simultaneusly.
Local, XServer and RDEsktop all in 1
This is 3 in 1 hidden! Local Windows XP Desktop using the "XManager" XServer runs rdesktop from my linux server which connects remotely to my laptop's Windows XP desktop! In this screenshot I didn't have to call an intermediate linux GUI but this can be possible also.
3 real desktops: local linux and windows remote
This is 3 in 1 visible! All 3 desktops are present. Local Workstation (Windows XP + XManager), Linux Server (Blackbox Xterm Rdesktop) and finally Notebook Win XP Desktop through Remote Desktop Connection.
Xvnc offering X-VNC services without an actual
                XServer!
Real VNC Server implementing the XWindow protocol inside Linux without a real XServer! RealVNC viewer on Windows!  Xvnc server scriptable, secure, user privileged, respawning on need! Also: TightVNC viewing Xfce4.



Although a dumb terminal may look naive nowdays, it's a little effort compairing to what it can save.
In a hard day that a network gets inaccessible or needs to be restarted or reconfigured from scratch, this little null modem serial cable can save lives.

The xserver screens would normally sit in the windows as an xwindow terminal page, but Microsoft's Remote Desktop Connection service
has extra features like printing services sound redirection and file transfer. Modern Linux distros include at least one RDC client.

Samba in Linux has gone better since ages: If we change the /etc/samba/smb.conf and save it (through a terminal or even an SMB share with special user permissions), the
samba daemon
(smbd) actively monitors the configuration file. No need to restart or send a signal to reread. Changes are instantly applied, from shares change to security model!

The VNC (Virtual Network Computing) System offers a variety of functions and abilities, depending on the various projects that implement it.
Xvnc (RealVNC cross-platform project) acts as an X & VNC server  without an actual graphical XServer running! x11vnc on the other hand, requires a real XServer to function.
Real VNC Enterprise edition offers file transfer encryption and print services! UltraVNC focuses on the Windows platform, offering file transfer encryption and chat!
The TightVNC cross-platform proj ect features image compression!
Viewers and servers from different projects are impressively compatible with each other!
All Unix/Linux oriented VNC projects are scriptable, run with user privileges, can respawn and work with Desktop managers!
