# Networking FreeDOS - TCP/IP applications

## Overview

      We heard in the "History of DOS networking" how popular TCP/IP
      applications for DOS were in the eighties and nineties of the last
      century. This era ended when Microsoft introduced Windows 95: It
      provided TCP/IP and other networking functions under an easy, user
      friendly interface. With their customers many commercial network
      applications for DOS vanished. But public domain software, freeware and
      shareware programs were preserved by the upcoming internet. Some are
      still developed today. Even new software has been written.
      DOS TCP/IP applications include classic networking tools as ping,
      lpr or finger as well as SSH and NFS clients, FTP servers, webservers,
      mail and news software or web browsers. There is even a complete peer-
      to-peer networking solution called "Network Enhanced Operating System"
      (NeOS - see: http://ftp.carnet.hr/pub/pc/networking/NeOS/README) which
      was developed 1995-2000 as part of European Union's "EUREKA" project
      (see: http://www.eureka.be/inaction/AcShowProject.do;jsessionid=
      7f00000122b839cfc1d1a5c44d359913f31b02769f2f?id=1317). Now it is
      postcardware.

## Links

      Michael Bernardi has collected a list of more than hundred TCP/IP
      applications (see: http://www.dendarii.co.uk/FAQs/dos-apps.html)
      available for DOS. There are also other lists here (see: ftp://ftp.
      technion.ac.il/pub/supported/pc/comm/drivers/pkt_drv/doc/software.doc),
      here (see: ftp://ftp.cac.psu.edu/pub/dos/info/tcpip.packages) and
      here (see: http://www.fdisk.com/doslynx/), which may contain additional
      information.
      A recent and constantly updated resource for DOS networking applications
      is the British "DOS Solutions" (see: http://www.dossolutions.pwp.
      blueyonder.co.uk/network.htm). Links to other DOS resources are
      collected in FreeDOS technote 157 (see: http://www.freedos.org/freedos/
      news/technote/157.html). I also found the nostalgia site oldskool.org
      (see: ftp://ftp.oldskool.org/pub/tvdog/internet/) pretty helpful.
      A lot of information can still retrieved from usenet newsgroup
      comp.protocols.tcp-ip.ibmpc (see: http://groups.google.com/group/
      comp.protocols.tcp-ip.ibmpc), especially from their FAQ, which is
      posted in parts one (see: http://www.uni-giessen.de/faq/archiv/
      ibmpc-tcp-ip-faq.part1-3/msg00000.html), two (see: http://www.
      uni-giessen.de/faq/archiv/ibmpc-tcp-ip-faq.part1-3/msg00001.html) and
      three (see: http://www.uni-giessen.de/faq/archiv/ibmpc-tcp-ip-faq.
      part1-3/msg00002.html).

## Applications

      It is not possible to cover all TCP/IP applications in this document.
      But here are some remarkable examples:

## Arachne

      (Picture of a screenshot of Arachne)

      "Arachne" is a graphical web browser for DOS. It was created in 1996
      by Czech programmer Michael Polak and his company xChaos/Arachne Labs
      (see: http://www.arachne.cz/). In 2002 Michael Polak decided to make
      Arachne free software. The new license is the GNU GPL
      (see: http://home.arachne.cz/archive/v01.n1917).
      The browser supports various picture formats. Tables and frames are
      shown correctly, it renders HTML 4 and CSS 1.0 and versions 1.90J3 and
      newer even understand UTF-8. Other Arachne services include FTP, NNTP,
      IRC-Chat, RSS, POP3 and SMTP. Look here (see: http://web.archive.org/
      web/20070311000724/http://www.cisnet.com/glennmcc/ara-gpl/history.txt)
      for a complete history of the software.
      Arachne is still actively developed - programmers are invited to join a
      mailing list (see: http://tech.groups.yahoo.com/group/ArachneDevelop
      ment/). The latest version can be found at the site of Glenn McCorkle
      (see: http://www.glennmcc.org/). Read more about it at Wikipedia.

## EZ-NOS2

      (Picture of a screenshot of EZ-NOS2)

      "EZ-NOS2" is one of the descendants of Phil Karn's KA9Q. It is
      currently developed by DOS Solutions (see: http://www.dossolutions.
      pwp.blueyonder.co.uk/eznos.htm). The software suite includes a webserver,
      a FTP-server and a bootp server as well as an email client.
      As all KA9Q descendants EZ-NOS2 is licensed with the GNU GPL. The source
      can be downloaded as ez_src.zip (see: http://www.dossolutions.pwp.
      blueyonder.co.uk/progs/eznos/ez_src.zip).

## SSH2DOS

      (The screenshot shows a closed SSH session to a Debian server.)

      "SSH2DOS" is a SSH, SFTP and SCP client for DOS. These services more
      and more replace the classic Telnet- and FTP-services, which are
      regarded as less secure.
      SSH2DOS was created by Hungarian developer Nagy Daniel in 2000 and can
      be downloaded at Sourceforge.net (see: http://sourceforge.net/projects/
      sshdos). It is released under the GNU GPL. It uses code of the PuTTY
      SSH client as well as the WatTCP kernel library.
