Jnos 2.0

HB3NOS is based on Jnos 2.0 (c) Maiko Langelaar, running on a Raspberry PI 3+ with Rasbian v4.1.6-v7. The Jnos server version that is running as part of HB1BBS services is modified on many aspects. I am working on making my own releases for personal use based on the previous works of many people, most notable are *Phil Karn (KA9Q), Johan Reinalda (WG7J), Gerard van der Grinten (PA0GRI), *Anders Klemets (SM0RGV), Kevin Hill (G1EMM), James Dugal (N5KNX), Brandon *Allbery (KF8NH), Barry Siegfried (K2MF) and Brian Lantz (KO4KS).

Application Services

HB3NOS Jnos server is running various services that are for internal use only. HB3NOS can be connected through the HB8NOS or HB9NOS node (just type JNOS at the prompt)


 

All about Jnos ?

Well, quite simply, JNOS is the "Swiss Army Knife" of Packet Radioi!!! 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....

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 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" commands 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?

What's happening? 

Langelaar.net (release history)

May 2020 - perhaps 2.0n was an exercise in getting 'carried away' ?(read the release history please for an update)

Apr 2020 - sanity check, emailed my Winlink account from outside, still able to pick off my messages from the Winlink CMS server using JNOS.

Mar 2020 - The source is available on my github account again

Feb 2020 - What started off as version 2.0m.1 has now been released as version 2.0n.beta - radical changes to password management, so I had no choice but to change the version MAJOR. Been playing with the SCS PTC-IIusb modem again, HF conditions not great. 

Oct 2019 - New version 2.0m (beta) - read the release hisstory for details.

Aug 2019 - Now able to accept packet connections from Winlink (RMS) Express clients, and go direct to CMS servers, just like an RMS node. I  just need to cleanup the code before I release any updates.

Jul 2019 - Very excited about a couple of things, first off, rediscovered the software combo of Paxon and PC/Flexnet32, still works in Windows 7 and it's been 15 years ? Excellent for an AXUDP packet terminal !
Now have base infrastructure in place to support packet connections from Winlink (RMS) Express clients and go direct to CMS servers. I was asked to support this, so making some good progress on it.

Mar 2019 - Been working on a new xterm based session manager as an alternative to ncurses. A previous maintainer of JNOS actually has it listed in the code as something they wanted to do years ago. I have made some progress, but ran into a major snag, and quite honestly ? I am not so sure I like the idea anymore, so giving it a break for a while.

So Jnos is still being developed, and is a complex TCP/IP packet program with lots of possibilities. Below are some items that deal with some of the possibilities.


Jnos on Raspberry Pi

If you desire to run JNOS on a Raspberry Pi, Jim Smith N8AVX has produced this excellent HOWTO that walks you through the entire process, step-by-step, to having a running JNOS application running on a Pi.

You start with a Pi with the Linux OS already loaded, follow these steps, and you will have a (minimal - autoexec.nos and a couple support files will need additional configuration) JNOS that can talk through either a USB or Serial port to your KISS TNC. Enjoy!!!

Configuring Jnos

The following files will need to be edited and configured for your JNOS station to operate properly. Each of these Example files contain a working configuration and contain instructions how to edit each section to customize the config for your particular station.

1) AUTOEXEC.NOS /jnos
This is the main configuration file. This is where we set the CALLSIGN, Hostname, IP Address, any SSID assignments, Aliases, and enable the services.
AUTOEXEC.NOS Example

2) FTPUSERS /jnos
This is a Password file. Here we create special priviledged accounts such as the root administration (those that can access special mainenance functions), and the UNIVPERM account which determines what services anyone without a specific account can do on the system. This file also determines who is a BBS and who is a human user. Change "  /jnos 0x4407f"  to reflect your callsign and your password. This account can use the "@" command to log into the JNOS Shell at the /jnos directory. From there this user can issue JNOS commands to change routes, clear mail queues, etc.
FTPUSERS Example 

3) DOMAIN.TXT /jnos
This is the DNS CACHE file. All DNS lookups get stored here. However, certain entries need to be made here so that a new JNOS node does not have "amnesia". A node *MUST KNOW* its own Hostname and IP Address in this file so that it can identify itself (oftentimes a problem when attempting to send SMTP email to a user on the box). Change the "YOUR-HOSTNAME-HERE.ampr.org." to reflect your Hostname or callsign. Change the "44.102.x.y" to match your IP address.
YOUR-HOSTNAME-HERE.ampr.org. 0 IN A 44.102.x.y
DOMAIN.TXT Example 

4) MAIL.CFG 
(helps with amnesia)
MAIL.CFG Example

5) LOCAL.RTE /jnos
This is the static route table. Here we define the DEFAULT route and any SUBNET routes and which Interfaces traffic to them will be routed. Change all SUBNET and INTERFACES to match your system.
LOCAL.RTE Example

6) INFO.HLP /jnos/spool/help/ 
This file contains the text that will be delivered to a user who types "I"nfo on the command line. This file SHOULD be brief but explain what and where this JNOS box is located. Adjust the text as you feel meets your needs.
INFO.HLP Example

7) AREAS /jnos/spool/ 
This file contains the mail area groups and are configurated in the rewrite file
AREAS Example

8) REWRITE /jnos/spool/
The rewrite file is used to perform a one-to-one mapping between destination addresses as received by NOS and destination addresses as actually used by NOS. Each record within the rewrite file comprises a single line, containing either two or three entries separated by spaces. The first field is the template field; if a destination address matches the template, it is replaced by the second field. The third field, which is optional, is the single letter "r", which, if present, tells NOS to rescan the rewrite file, using the new destination address to attempt to match against the templates.
REWRITE Example
