atmhosts - ATM host name file
The atmhosts file is an ASCII file that contains an single-line entry for
each host on the ATM network. Each entry consists of an ATM host address,
official host name, and any aliases.
Parameters are separated by spaces or tab characters. A number sign (#)
indicates the beginning of a comment; characters up to the end of the line
are not interpreted by routines that search the file.
ATM host addresses are specified by an even number of hexadecimal digits.
Each pair of digits represents 8 bits of address information. An ATM
address can be one of the following:
+ An ATM End System Address (AESA) as registered with the network (19
bytes, or 38 hexadecimal digits)
+ A local Endpoint System Identifier (ESI) that is registered with the
local switch (6 bytes, or 12 hexadecimal digits)
+ An AESA with selector byte, representing the address of a service on a
remote machine (20 bytes, or 40 hexadecimal digits).
By default, the atmhosts file contains an entry for Permanent Virtual
Circuits (PVCs). The entry consists of an ATM address of 40 hexade-
cimal zeros (0) and the host name PVC. Do not change or delete this
