/etc/ppp/options Configuration File

You use the /etc/ppp/options file to define global options for all PPP communications on the local machine. /etc/ppp/options is a privileged file. /etc/ppp/options should be owned by root, although pppd does not enforce this rule. Options that you define in /etc/ppp/options have precedence over definitions of the same options in all other files and the command line.

    Typical options that you might use in /etc/ppp/options include the following:

  • lock – Enables UUCP-style file locking

  • noauth – Indicates that the machine does not authenticate callers

Note - The Solaris PPP 4.0 software does not include a default /etc/ppp/options file. pppd does not require the /etc/ppp/options file to work. If a machine does not have an /etc/ppp/options file, only root can run pppd on that machine.

You must create /etc/ppp/options by using a text editor, as shown in How to Define Communications Over the Serial Line. If a machine does not require global options, you can create an empty /etc/ppp/options file. Then, both root and regular users can run pppd on the local machine.

/etc/ppp/options.tmpl Template

The /etc/ppp/options.tmpl contains helpful comments about the /etc/ppp/options file plus three common options for the global /etc/ppp/options file.

Enables UUCP-style file locking
Specifies that no default route is defined
Disallows proxyarp

To use /etc/ppp/options.tmpl as the global options file, rename /etc/ppp/options.tmpl to /etc/ppp/options. Then, modify the file contents as needed by your site.
