  1.  Description of the nodelist format
  --------------------------------------

  Every node entry contains the following 8 fields:

  keyword,node_number,node_name,location,sysop_name,
  phone_number,baud_rate,flags

  Certain fields have defined values according to FTS-0005.

  1.1.  Implementation for IP-connectivity
  Because of the limited characterset in the phone_field and
  to avoid any misinterpretion by conventional dialing, the
  ip-specific address-information is entered in another field
  and there are additional flags required.

  1.1.1.  Field #1 (keyword) is PVT for an ip-only node without
  conventional phone number related connectivity. In this
  case, the phone field contains "-Unpublished-" according
  to FTS-0005.

  1.1.2.  Field #2 (node_number) contains the node number within his
  net and zone.

  1.1.3.  Field #3 (node_name) is used for the FQDN (Fully Qualified
  Domain Name) or the ip-address.

  1.1.4.  Field #4 (location) contains the geographical location of
  the node. While some nets/regions cannot supply their
  ip-only nodes with a adequate link, these nodes may be
  collected in a seperate net or region, until their original
  net/region support additional ip-connectivity. This special
  net/region is definitely a temporary solution for routing
  within a region or zone!

  1.1.5.  Field #5 (sysop_name) represants the name of the system
  operator.

  1.1.6.  Field #6 (phone_number) contains the phone_number for
  conventional connectivity. In case of an ip-only node
  it must contain "-Unpublished-".

  1.1.7.  Field #7 (baud_rate) contains the maximum baud rate for
  conventional connectivity or 300 in case of an ip_only node.

  1.1.8.  Field #8 (flags) represents operational definitions for the
  node.
  The ip-flags consist of two parts:
  A basic transport and an optional non-standard port,
  seperated by a colon.
  The default port may be omitted, but is listed as optional
  parameter in this document. In some cases, two flag names
  are mentioned:
  The second one is supported by some software nowadays, but
  these values may conflict with other programs, which not
  completely decode the length of each individual flag (i.e.
  TELN conflicts with the T-flag for online-time)
  Additional flags for ip-nodes are:

  1.1.8.1.  IBN[:24554] (Argus: BND[:24554])
  BinkP protocol

  1.1.8.2.  IFC[:60179]
  Raw protocol as used by ifcico

  1.1.8.3.  ITN[:23] (Argus: TEL[:23])
  Telnet protocol. Some variants of ifcico support Telnet
  on port 60177, which should be added as additional flag
  ITN:60177.

  1.1.8.4.  IVM[:3141]
  Vmodem protocol

  1.1.8.5.  IP
  General flag for special protocol specifications, if the
  flags conforming to 1.1.8.1. to 1.1.8.4. are not relevant.

  1.1.9.  Comments on the proposed nodelist flags
  The additional flagnames in () are supported at this moment
  by Argus, based on the use in z2r50. But the TEL[NET]-flag
  stays in conflict with the generally in all zones and
  regions used T-flag (online time according to FSC-0062).


  2.  Optional extensions for future use
  --------------------------------------

  While the above mentioned flags (1.1.8.1 to 1.1.8.4) define a
  minimum set of operational flags for ip-nodes, several additions
  are already foreseeable at this moment.

  2.1.  Additional sessions_handshake parameters
  There is at least one program, which supports several
  transport protocols according to chapter 1.1.8. on a
  single port. If other programs should imitate this habit,
  then the following extension to the flag suite 1.1.8.
  (transport[:port[:handshake]])is advised:

  2.1.1.  FTS-0001 session handshake:   1
  2.1.2.  Yoohoo session handshake  :   Y
  2.1.3.  EMSI sessions handshake   :   E
  2.1.4.  BinkP sessions handshake  :   B

  2.2.  Non-handshaking protocols
  While the definitions until this chapter describe direct
  handshaking sessions with optional password authentification,
  there are several other methods for the tunneling of fidonet
  data via the internet available.
  The setup of these connections does not rely on the nodelist
  (at this moment of writing), but we can think of standard
  setup procedures to use the nodelist for configuration of
  this additional transport methods.
  Therefore the following flags 2.2.1. to 2.2.4. are advised
  for at least informational purpose.

  2.2.1.  IFT
  FTP (File Transfer Protocol)

  2.2.2.  ITX
  TransX, an Email based variant

  2.2.3.  IUC
  Uuencoded packet (one packet per message)

  2.2.4.  IEM
  Email based (generally, without exact specification at
  this moment)


  3.  Addendum
  ------------

  This proposal is based on a maximum compatibility to generally used
  definitions and standards within the Fidonet community.
  Future developments might make additions necessary, if they can not
  be expressed with the existing set of flags as defined by this FSP.
