Hello Jeff,

On Saturday October 31 2020 12:38, you wrote to Carol Shenkenberger:

 JS> If a non-standard port is in use I use the syntax INA:FQDN/IP:

Different protocols use different ports. A port is associated with one specific
protocol and one protocol only. If a protocol uses a port not standard for that
protocol that non standard port applies to that protocol only. Therefore a non
standard port should be attached to the protocol flag.

The INA flag is not a protocol flag, but a server address flag. It never
carries a port number, just an address.

So this:

,26,Stepping_Stone_BBS,Wichita_Kansas,Jon_Justvig,-Unpublished-,300,CM,INA::ste
ppingstone bbs.com:24555,CM,ITN,IBN

  ... is wrong. (apart from the double CM flag) The proper way to list is:

,26,Stepping_Stone_BBS,Wichita_Kansas,Jon_Justvig,-Unpublished-,300,CM,INA:step
pingstoneb bs.com,ITN,IBN:24555

The system is connectable via steppingstonebbs.com and supports two protocols:
IBN and ITN. ITN via the standard port 23 and IBN via the non stamdard port
24555.


From FTS-5001.006:

  There are five classes of Internet Capability flags:


   .1 Internet Protocol Flags
   --------------------------

   Internet Protocol flags use the syntax:

   [:][:]

   Where  is:
   * a fully qualified domain name (FQDN), or
   * an IPv6 address encased in square brackets, or
   * an IPv4 address in dotted-quad format

   and  is the decimal service port number. A port number
   should only be specified if it is not the default port number
   for that protocol.


        Default
   Flag     port Description
   --------------------------


   IBN    24554  Binkp (FTS-1026 - FTS-1030)
   IFC    60179  RAW ifcico (FTS-1024)
   IFT       21  FTP (RFC-0959); Note there is currently no widely
                 accepted authentication scheme for FTP transfers by
                 Fidonet mailers.
   ITN       23  Telnet connection using FTS-1 or any other protocol
                 designed for classic POTS and modem.
   IVM     3141  Vmodem connection using FTS-1 or any other protocol
                 designed for classic POTS and modem.
   IP      none  Mostly used during the introduction of IP capable
                 systems to the nodelist. Denotes an unspecified
                 protocol. (Deprecated)


   .2 Server Address Flags
   -------------------------

   Server address flags use the syntax:

   :

   Where  is the same as for protocol flags.
   These flags are used to specify a server address for Internet
   Protocol Flags that do not specify an address themselves.

   Flag          Description
   -------------------------

   INA           This flag sets a default server address used
                 for any Internet Protocol Flag that does not
                 specify its own.


   .3 Internet Information Flags
   -----------------------------

   Internet Informations Flags use the syntax:

   

   These flags are used to signal additional information
   regarding the internet connection.

   Flag          Description
   -------------------------

   INO4          Indicates that an otherwise IP capable node is
                 unable to accept incoming connections over IPv4.
                 (FRL-1038)
   ICM           Node accepts mail 24 hours a day using all listed
                 TCP/IP methods, but not all of the other listed
                 methods (such as PSTN/ISDN) and therefore cannot
                 be CM.  See FRL-1017.
                 See also the CM flag under section 5.1

Hope this helps.
