My friend Jay Nugent (WB8TKL) has set up a very informative page on what
is JNOS and how can it be configured (even on Raspberry Pi computers).
This is what I have been running since late 1997, first as a DOS window
on a Win95 PC, then Win98 and then Linux.  Feel free to share this with
other current/future packet sysops who are not on this mailing list.

Here is the opening of his webpage http://www.mi-drg.org/jnos.html

What is JNOS and What Does It Do?

Well, quite simply, JNOS is the "Swiss Army Knife" of Packet Radio!!! 
Because it can do just about anything. It's a TCP/IP router, firewall, 
BBS, SMTP/FTP/WEB server, and talks AX.25, NetROM, and TCP/IP protocols. 
And it does APRS and WINLINK. Read on....

Just look at all the things it can do:

- JNOS is an "Operating System" *NOT* an Application.
- It acts as a Digipeater and/or a cross-band Digipeater
- You can uplink and downlink with it using plain old AX.25
- It contains a BBS "Bulletin Board System"
- It can have any number of radio interfaces/ports
- It can act as a File Server (using the "Upload" and "Download" BBS 
commands, of FTP)
- It supports the complete TCP/IP protocol suite (Telnet, Finger, FTP, 
Ping, ARP, SMTP email, POP3 for Email, HTTP web, and anything than will 
run atop IP)
- It supports an Ethernet port(s) and can be connected to your LAN or to 
the Internet
- It supports NetROM/Knet protocol and can link with NetROM nodes/networks
- It supports AXUDP links to other systems (such as BPQ nodes)
- It supports a WINLINK interface to exchange Email with that network.
- It can be an APRS Digi as well as an Igate.
- It supports RLI/FBB "Heirarchical" email forwarding.
- It supports a Network-Wide CONVerse Bridge that supports over 32,000 
individual CHAT channels (911 for Emergencies, 411 for Weather events, 
individual County channels (81), individual District channels (222), and 
even links to bridges throughout the World)
- It supports TCP/IP over the top of the AX.25 Link Layer protocol.
- It supports TCP/IP over the top of the NetROM networks.
- It supports TCP/IP routing using conventional "ifconfig" and "route" 
- It supports IPIP ENCAP (Protocol-4) for easy linking across 
non-Amateur networks such as the Internet or microwave/mesh networks.
- It contains IP ACCESS and TCP ACCESS firewall
- It has built-in detailed HELP files
- SMTP Email can have multiple recipients
- SMTP Email can have MIME Attachements
- It has very robust daily Logging of all logins, actions, logout, and 
SMTP/FTP transactions.
- It has Remote management access and rebooting capability.
- It supports SNMP network management and monitoring tools.
- And it can be configured to do ALL OF THE ABOVE at the same time!!!
- Have I missed anything.......???
