The ihost is currently the main Unix/Linux/FreeBSD host application for |

i-scream. ihost is centrally configured by the server it connects to |
| 119 |
and periodically sends information about the machine on which it is |

running. The ihost is written in Perl, so can be easily altered to |
| 121 |
send extra information to your i-scream server.</font> |

The WinHost is similar in concept to the ihost, however, this one runs on |
| 130 |
Windows NT/2000 servers. Again, the configuration is dynamically |
| 131 |
obtained from the server. The WinHost is typically only present in |
| 132 |
the Windows system tray. Double clicking on the system tray icon |
| 133 |
will bring up a small window that allows data to be viewed and to force |
| 134 |
reconfiguration with the server.</font> |
