The transmitter Wilsdruff is a medium wave radio broadcasting facility near Wilsdruff, Germany. Until the nineties there was a transmitter for 1044 kHz with 250 kilowatts transmission power.

The new transmitter is in a circular building on which the mast stands. The old transmitter of the fifties is a technical monument.

As an example of rsh use, the following executes the command mkdir testdir as user remoteuser on the computer host.example.com running a UNIX-like system:
The rsh command has the same name as another common UNIX utility, the restricted shell, which first appeared in PWB/UNIX; in System V Release 4, the restricted shell is often located at /usr/bin/rsh.
As described in the rlogin article, the rsh protocol is not secure for network use, because it sends unencrypted information over the network, among other reasons. Some implementations also authenticate by sending unencrypted passwords over the network. rsh has largely been replaced with the secure shell (ssh) program, even on local networks.
After the command has finished rsh terminates. If no command is specified then rsh will log in on the remote system using rlogin. The network location of the remote computer is looked up using the Domain Name System.
