Networking FreeDOS - TCP/IP applications


  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: which
  was developed 1995-2000 as part of European Union's "EUREKA" project
  7f00000122b839cfc1d1a5c44d359913f31b02769f2f?id=1317). Now it is

  Michael Bernardi has collected a list of more than hundred TCP/IP
  applications (see:
  available for DOS. There are also other lists here (see: ftp://ftp.,
  here (see: and
  here (see:, which may contain additional
  A recent and constantly updated resource for DOS networking applications
  is the British "DOS Solutions" (see: http://www.dossolutions.pwp. Links to other DOS resources are
  collected in FreeDOS technote 157 (see:
  news/technote/157.html). I also found the nostalgia site
  (see: pretty helpful.
  A lot of information can still retrieved from usenet newsgroup
  comp.protocols.tcp-ip.ibmpc (see:
  comp.protocols.tcp-ip.ibmpc), especially from their FAQ, which is
  posted in parts one (see:
  ibmpc-tcp-ip-faq.part1-3/msg00000.html), two (see: http://www. and
  three (see:

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

  "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: In 2002 Michael Polak decided to make
  Arachne free software. The new license is the GNU GPL
  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:
  for a complete history of the software.
  Arachne is still actively developed - programmers are invited to join a
  mailing list (see:
  ment/). The latest version can be found at the site of Glenn McCorkle
  (see: Read more about it at Wikipedia.

  "EZ-NOS2" is one of the descendants of Phil Karn's KA9Q. It is
  currently developed by DOS Solutions (see: http://www.dossolutions. 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 (see: http://www.dossolutions.pwp.

  "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 (see:
  sshdos). It is released under the GNU GPL. It uses code of the PuTTY
  SSH client as well as the WatTCP kernel library.
