Appendix G - IPSEC

User Guide 397

begin with white space too. There may be only one section of a given type with a given

name.

Lines within the section are generally of the following form:

parameter=value

(Note the mandatory preceding white space.) There can be white space on either side of the

=. Parameter names follow the same syntax as section names, and are specific to a section

type. Unless otherwise explicitly specified, no parameter name may appear more than once

in a section.

An empty value stands for the system default value (if any) of the parameter, i.e., it is roughly

equivalent to omitting the parameter line entirely. A value may contain white space only if

the entire value is enclosed in double quotes ("); a value cannot itself contain a double quote,

nor may it be continued across more than one line.

Numeric values are specified to be either an integer (a sequence of digits) or a decimal num-

ber (sequence of digits optionally followed by “.” and another sequence of digits).

There is currently one parameter which is available in any type of section:

A section with name %default specifies defaults for sections of the same type. For each

parameter in it, any section of that type which does not have a parameter of the same name

gets a copy of the one from the %default section. There may be multiple %default sections of

a given type, but only one default may be supplied for any specific parameter name, and all

%default sections of a given type must precede all non-%default sections of that type. %default

sections may not contain also parameters.

Currently there are two types of sections: a config section specifies general configuration

information for IPsec, while a conn section specifies an IPsec connection.

also The value is a section name; the parameters of that section are appended to this

section, as if they had been written as part of it. The specified section must exist,

must follow the current one, and must have the same section type. (Nesting is

permitted, and there may be more than one also in a single section, although it is

forbidden to append the same section more than once.) This allows, for example,

keeping the encryption keys for a connection in a separate file from the rest of

the description, by using both an also parameter and an include line.
