I know this is kinda weird, but has anybody ever done a wireless network
using ham radio or CB radio to transmit. If so, what is the maximum distance
you can get up to. I dont really care about security or anything, I'm really
a newbie (1 month) to linux and the idea intrigued me since I am a ham radio
operator. Is it do-able and can many people tap your data?

THank in Advance

Do a engine search on "packet" you'll find all the info you need.
Jnos and Tnos are the two main TCP/IP packet programs with
Tnos being state of the art but not that user friendly. Take a look
in the ARRL repeater directory for the digital frequency's and
scan them to see if you hear anyone on 2m or 70cm. As far as
security most non AMPR are blocked i.e. non 44.XX.XX.XX
with mail being the exception in most cases common sense with
networking should keep the system pretty safe, or as the story goes
unplug it and put it in the closet if you want to be real safe :))

1. TNT V0.9 Packet Radio Hostmode Terminal (Ham Radio)

Announcing TNT V0.9 for Linux
-----------------------------

TNT - A Hostmode Terminal Program for Packet Radio
--------------------------------------------------

Packet Radio is a name for a packet oriented data protocol used
in Ham Radio. It is a special adaption of the X.25 protocol.

TNT does NOT implement this protocol, it needs a TNC (Terminal Node
Controller) with WA8DED Software or The Firmware by NORD><LINK.
TNT uses the hostmode which is implemented in these TNC-Firmwares
(The Firmware is available for all TNC2-clones, AEA PK232 and PK88).

TNT has totally different goals than the existing programs or kernel
extensions (Wampes, NOS, KA9Q, AX25 kernel driver, e.t.c.).
TNT does not use the packet radio connection as an additional network
interface of Linux, it is simply a program to make packet radio connections
with a comfortable user interface (I hope so...).

In release 0.9 many new features were implemented, but still TNT is in the
development phase, the implemented features are quite stable, but new
features are under test and not yet released.

TNT features:
- uses Linux console or termcap entries, runs from remote terminals
- no special kernel requirements, no patches needed
- virtual screens for all connections, for commands and for monitoring
- scrollback buffer on all virtual screens
- logging of received data
- sending of files
- connect text with macros for time, callsign e.t.c.
- fortune cookie sending if someone connects
- remote commands
- remote login to Linux
- redirection of input/output of a connection
- binary file transfer
- logbook
- connect script
- internet socket, use of TNT by a user of a different host
- extended monitor to read other connections on the frequency
- boxlist, help for using BBS's
- NETROM/TheNet header analysis
- heard list
- keyboard macros
- password generation

TNT is available via anonymous ftp from
   quepasa.cs.tu-berlin.de (130.149.17.7)
in directory
   pub/linux/hamradio/packet-radio
with name
   tntsrc09.tgz (tar-gzip-archive)

This program is a little try to give back to the Linux community what the
Linux community has given to me (bringing back the fun to computing).

Your comments, ideas, code changes, new features are very welcome!
