TCPIP Notes

.
For those that want to start, learn, experiment about AMPRNet, Internet networking and TCP/IP services.

3.3.2024 NOTE GB7CIP theskywaves.net STATIC PUBLIC IPADDRESS CHANGED Again by our 'ISP' (5.3.2024).
Recommend that you use the hostname gb7cip.theskywaves.net in your agreed INTERNET UDP GB7CIP tunnel link Configurations..
Or Replace OLD 82.70.39.222 for those with 'NON 44Net' address detailed in the documents with the above hostname..

Issues accessing these systems services currently being investigated since ISP's network changes 1.3.2024 outside the control of
GB7CIP's SysOP. Believes these have all now be resolved as at 6.4.2024. (though have lost contact with some remote links)
SysOP's BRAIN OVERLOADED!! Resolving issues with all the Network components.
(Unless you know better - please advise G4APL)

PS 6.3.2024 ISP has advised the SysOP of this system, that a NEW /29 Static subnet will be assigned
to this system, replacing the original /29 subnet. Awaiting further details.

What is the AMPRNet? I hear you cry!

Real Time Amateur Radio. If you have a valid Amateur Radio Licence.
You could use XCHAT to connect to the Real Time Converse server attached to this amprnet System.
Need to liaise with the Sysop first.

XXMCLIENT
Chris G8XXM has kindly supplied the following notes to assist those
that require a Linux Client to access the many linux Nodes in operation.
Including the host gb7cip run by Paul G4APL.

XXMCLIENT_Guide_By_G8XMM

This guide will allow you to connect (as a client), to the AMPR (44.net)
network from 'any' Linux box. From there you can connect to any BBS,
ftp or CONVerse Server.
Credit to KB9MWR, I just hacked his script.
See https://www.qsl.net/kb9mwr/wapr/

It has been tested on Raspberry Pi (raspian),
and Debian 10, but should work on Redhat/Suse even a 'live' USB Linux.

This guide has been written using Debian (apt-get) but you should be able to work it out for other
Linux flavours using (Yum/dpkg/rpm/etc).

It will NOT work on Apple Mac or Windows PC as they do not (by default),
support IPIP (protocol 4 ipencap).

You can run the script as root (or sudo su) as it is not running any servers/services that are
exposed to the Internet.
You do NOT need to open any network ports or do any port forwarding on your ISP provided router. :)

Mozilla's Thunderbird
http://www.mozilla.org/en-GB/thunderbird/
Open source cross-platform email and Usenet client based on Mozilla code. Features intelligent spam filters, built-in RSS reader, and quick search.

Use Mozilla's Thunderbird to access your FBB SP Mail and Bulletins
Note: You need to have manually created your LinFBB user account first and completed all fields.

You can now use Thunderbird(mail/news) to connect to the GB7CIP LinFBB 7.0.11 server via the Internet or amprnet.
Additional step by step draft notes as a result of a Windows 10 installation 'experience'

GB7CIP now has a user using a Mobile Phone (AndroidOS) using K-9 Mail to read and send
(SP AX25 Mail) mail.

The firewalls have now been configured so you can use the pop3(port 6110)/smtp(port 6025)
to read and send your
SP(email) to and from the GB7CIP LinFBB server.
also AX25 Bulletins (nntp newsgroups)

Address the SP mail address as you would do. i.e.
when using a standard AX25 Client. CALLSIGN@BBSCALL.#Area.COUNTRY.CONTINENT
You can also use Reply to messages and bulletins received.

Important:
For a bulletins, again address as you would do as when using an AX25 Client. e.g.
ALL@LOCAL
TECH@WW
DX@EU
ALL@GBR

Remember your LinFBB SysOp needs to enable Telnet access on your LinFBB User account.
YOU! need to disable paging if you have it enabled. Using the OP command.

All messages need to be plain text by default

TNC2PPP eprom info for TNC2+WIN95/98 (3Kbytes) enter TNC2PPP at bbs prompt(g4apl has this working on win98pc driving a BSX2 TNC)

The simplest version to get going if you have a TNC2 clone
(e.g. Tiny2, TNC200, BSX2) or Baycom, in JNOS running under DOS or a DOS window.
Though we only have experience of using TNC2's.

	You can always do your own thing afterwards, once you have got going and gained some experience. e.g.
a)	TCPIP Over AX25 Paul found that he could set-up this system up and working in 30 minutes using an Ethernet Virtual Driver and an Ax25inet interface to drive a TNC2 in KISS mode. Allowing all the windows IP enable programs to access the local TCPIP GB7CIP server over 1200bd or 9600bd radio Interfaces TCPIP over AX25 document (Links referred to in this document are no longer active)
b)	AGW_TCPIP Using your windows system soundcard to generate the tones and drive your transceiver. (or AGW drive the TNC in KISS mode)
c)	Windows Setup your Win3.11, win95/98,2000,XP PC to route via the jnos PC over the Ethernet connection between the jnos and windows machines.
	Windows 10,11 UZ7HO SOUNDMODEM EASYTERM AX25 Over FM 2metres or 70cm 1200bd IP amprnet access to GB7CIP Networks Node, Convers and BBS. IP over AX25 Radio network and routing. Reminder! Modern radios may have slow RX/TX change overs compared to the old radios. . So you will need to experiment and adjust the :- TXTail and TXDelay values. TXTail 10 (x10msecs) TXDelay Suggest start at 42(x10 420msec) and test down to 30(x10 300msec) Until you fail to get a two way communication with GB7CIP VHF UHF radios. The above applies to all software modems and hardware TNC/Data Controllers.
d)	MixW Reported to work well on TCP/IP using windows sound card. Win98, ME, 2000, XP. g4apl has had no experience of this software. Other than spoken to a station nr Bristol via the amprnet ip network who is very please with the system. MixW Web Site G4APL has MIXW driving the Kenwood THD7e and TS2000e direct AX25 Mode 1200bd and 9600bd RF successfully. Does not have the TCP IP over AX25 wrapper installed.
e)	URONode (Popular with the USA and UK and elsewhere in the world) Note: Brian N1URO became a Silent Key 4.1.2022. RIP MY Friend de Paul G4APL URONode is a friendly User frontend that sits on top of the Linux ax25 tools, utils, apps and IP networking software which gb7cip uses on a very busy hard disk based system, instead of LinuxNode(which had security issues). It supports cross-port digipeating, automatic routing, various IP functions, and ANSI colours. There is also a Raspberry Pi image distribution that take ten minutes to configure and get up and running. Once the image is on a SD memory card and plugged into the Raspberry Pi. Note G4APL only Uses AX25 NetRom TCPIP (not FLexnet or ROSE) for the UK Network. http://sourceforge.net/projects/uronode/ http://uronode.sourceforge.net G4APL Linux build is referred to in the DataOverAmateurRadioNetworks web page
f)	XRouter Use Paula's (g8pzt) XROUTER on a scrap Dos PC connected to your Windows PC over the Ethernet. (Quite easy to setup once you have read the manual, PC min specification 386 640KB ram, small hard disk, serial ports, TNC, Ethernet card) or run XROUTER on it's own. Then use the standard Windows supplied internet programs Web Browser e.g. via radio web server http://gb7cip.ampr.org Telnet, FTP, Outlook or Outlook Express for pop3(mail) and nntp (Bulletins) network games over TCP/IP etc. and any other program that uses TCP/IP There is also a XRouter version for the RPI Raspberry Pi, that runs on top of a linux ax25 tcpip build as another network. Using the the main linux host as it's gateway. (Tested by G4APL in early 2019)
g)	G4HIP NNTP for VIRGINS. These are the notes extracted from the article written by G4HIP. "A little screed on getting an NNTP server working with NOS. While intended for those using TNOS developed by Brian Lantz, it may be of help to other NOS users as well." Can be article found on the attached link G4HIP NNTP for VIRGINS
h)	Microsoft Outlook Express If you use Microsoft Outlook to post NNTP (news articles, equivalent to ax25 bulletins) on the TCP/IP AMateur Radio Packet NETwork. server gb7cip.ampr.org For some tips re Distribution: field values (uk, europe, world, ampr, amsat) NNTP Latest list of UKIP Newsgroups xfbb<>nntp gateway feed to gb7cip.#32.gbr.euro GB7CIP was requested by London Regional IP Coordinator to provide nntp service and feed for London and home counties 12 August 1997 double click to download the current newsgroups NNTPGROUPS (If using Internet Explorer (IE) you may need to right click on NNTPGROUPS and select " save target as" to save as file) Latest UKIP NNTP gateway.txt file use by UK NNTP Gateway Hubs. updated and maintained by g4apl Please enter OUTLOOK for tips of how to add these entries Note: very few use the original Usenet nntp services these days,
i)	NNTP EMAIL Dialog Another Email, NNTP Newsreader that you may like to experiment with is Dialog from 40tude Web site. We have run it under Windows XPpro and Win 98 successfully sending and receiving Email and News Articles from gb7cip. It is very configurable and could replace Outlook.
j)	MAILGW 0.3.1.8 Modified by G4HIP assisted Paul G4APL to fix major bugs back in 1998/1999. This gb7cip.ampr.org gateway system has been operational since 1999. This is a Linux suite of applications that are used with INN and SENDMAIL at GB7CIP. Now working with INN2 2.5.3.3 and current version of Sendmail 8.14.4-4.1 Very Complicated to configure - This configuration is Not Supported. Here are the latest map files based on the gateway.txt file. It is assumed that you have a fully working MAILGW 0.3.1.8 AX25<>TCPIP gateway using the following files. distribution.map newsgroup.map bulletin.map MAILGW 0.3.1 G4HIP Patches. refer to G4HIP Web site
k)	JNOS (UKNOS Suite) MSDOS Revisited by G4APL as another "request" 'challenge' to get this running under WinXPpro and Win7Pro(Windows Virtual Server+Windows-XP-Mode) Driving the Internal TNC in his Kenwood THD7e(tnc) and TS2000e(tnc) Sub Receiver (Succeeded) 18.3.2018 Using programs complied in the late 1990's, Early 2000's. Jnos example of the resulting autoexec.nos config file updated 18.3.2018 Also available for download from AX25 GB7CIP xfbb BBS Server using 7plus 7PSERV command. G4APL has MSDOS JNOS(UKNOS) running on WinXPpro, Win7Pro+Msoft Virtual Server+XP_Mode_server driving a Kenwood THD7e (TS2000e, TMD710) in KISS Mode and RF at 1200baud or 9600baud 144, 432, 433, 439MHz. Found that the following setting of tcp mss 196 was required, instead of 216 for the Kenwood TASCO RADIO MODEMS. On exit the Internal TNC's are reset back to defaults and available to be driven by DOS program Paket62 in standard AX25 Packet Mode. . Jnos commands Manual (1994) in pdf format
l)	(SMTP ROUTING FIX, IF ROUTING VIA A DEDICATED ROUTER e.g. GB7CP enter SMTPFIX at bbs prompt)
m)	JNOS program function Keys
1)	The version that the Caterham SysOp's suggest you use is a self installing package called nosins2k.zip (1.39Mbytes) Old no longer supported- noted here for history.
2)	YAPP from gb7cip directory yapp/tcpip/nosins2k.zipNote: The XFBB Server here does it's housekeeping at 02:00 hours and restarts .
3)	7PLUS connect to GB7CIP(CIPBBS) then issue the command 7pserv yapp/tcpip/nosins2k.zip this will send you 70+ files of 15 Kilobytes each.
n)	JNOS WEB SITE The latest releases can be found on Maiko's ve4klm Website Linux Primary platform DOS version can be run on Windows and OS2 (Expect that it can be run in DOSBOX on other platforms) WIN32 and Mac OS.X JNOS2 WIN32 (Native Windows) version by Maiko ve4klm Connect over the Amprnet AMateurPacketRadioNETwork using a sound Card and Multipsk For more details can be found on Maiko's Website I have not tested this de g4apl
	You will need to identify your local TCP/IP server and frequency that you will use to access your local hub(Server) and the rest of the TCP/IP network In the UK check out 9600bd 432.625MHz, 439.950MHz, 1200bd 433.625MHz, 144.925MHz, 144.9375MHz .
o	IP OVER AX25 Using Windows PC and Soundcard Wanted a simple description on how to install soundcard driver to support IP over AX25 for use at 1200bd and or 9600bd on 144.9375 432.675. (432.625(9600bd) (439.950(9600)) Needs to be simple step by step guide, for non technical computer users to install and get up and running on their system to drive their FM VHF/UHF Radio
	GB7CIP Getting started You are most welcome to use gb7cip.ampr.org if you can access one of our frequencies direct. (makes our life easier as we can assist in helping you getting it going if you use the suggested software and a TNC or a Kenwood Radio with the built in TASCO RADIO MODEM TNC). Connect to gb7cip-5 uronode friendly front-end user interface via NetRom, or via one of the ax25 uplink aliases CRNODE or CATHAM and enter info and INTerfaces for details. Once you have the software and keen to get up and running, you will require an amprnet TCP/IP address to be allocated to you. Information required (please send to g4apl) Did you previously hold, currently hold another callsign, or been allocated a 44.amprnet IP address previously if you can remember it. No problem if not. Please advise all the UK callsigns you have held. e.g. Foundation, Intermediate, A/B, A, B Licence. QTH (TCP/IP addresses are issued based on where you live Also there are generic area alloctions at the bottom of the ampr.portal.org 44.131.0.0 lists being encouraged) (as explained in UK IP ADDRESSING SCHEME) Local TCP/IP HUB and frequency that you plan to use for your local access point of presence (POP) to the network. (Just like you use your Internet ISP for access) Log on to the amprnet portal link listed below.
	Further advice can be gained by chatting live to the support group on the local convers channel 11 Connect to CRGWAY(GB7CIP-5) CRNODE(MB7NCR) or telnet 44.131.244.1 port 23 or 6301 then enter the command CONV The TCP/IP co-coordinator will liaise with the respective sysop.
