Modifying the /etc/protocols File
The /etc/protocols file associates port numbers with mnemonic names and alias names.
The /etc/protocols file contains the names and protocol numbers of all protocols known to
your local host. The netstat diagnostic uses the /etc/protocols file. If you install HP-UX
Internet Services or HP-UX NFS, those products will also use the /etc/protocols file.
NOTE You can modify this file if you have special requirements, but it is properly
configured when you receive the HP-UX LAN software.
/etc/protocols
Each protocol has a one line entry in the /etc/protocols file. Each entry in /etc/protocols
file takes the following form:
Syntax
protocol_name protocol_num [ alias ]...
Parameters
protocol_name Name of the protocol. Protocol names can contain any printable character
except spaces, newline, or the comment character (#).
protocol_num Protocol number that identifies this protocol.
alias Common name or names for the protocol. An alias is a substitute for
protocol_name . Alias names are optional.
/etc/protocols Format
• Lines cannot start with a blank or tab character.
• Fields can have any number of blanks or tab characters separating them.
• Comments are allowed and designated by a pound sign (#) character preceding the
comment text.
