The context-sensitive helps in this file are used by both SMIT and Web-based System Manager.
Specify a character string without spaces for giving a unique identity to the system within a PPP network. This name is used by point-to-point configuration only.
Specify the maximum number of server links that the PPP LCP multiplexor will support.
Specify the maximum number of client links that the PPP LCP multiplexor will support.
Note that client IP interfaces are generated for all specified client links, up to the maximum number of interfaces configured.
Specify the maximum number of demand links that you want the PPP LCP multiplexor to support. Set this value to the number of demand interfaces that you expect to configure. The default value is 0.
Specify the number of TCP/IP interfaces allowed for a point-to-point link configuration.
Specify the maximum number of asynchronous PPP connections that can be active concurrently. This parameter supports proper configuration of HDLC encapsulation.
Removes the /etc/ppp/lcp_config file. When the /etc/ppp/lcp_config file does not exist, the PPP subsystem cannot be started.
Define the Maximum Receive Unit (MRU) that will be negotiated. The default MRU is 1500 and should be sufficient for most needs. The MRU should not exceed 4096.
Specify as a bit mask the control characters that cannot be successfully received over a serial line. PPP requests the peer to send these characters as 2-byte escape sequences instead.
The value of this field is a 32-bit hexadecimal number. Each bit represents a character to escape. The most significant bit represents character 0x1f and the least significant bit represents character 0x00. Only characters 0x00 through 0x1f can be escaped. The default setting (that is, a blank field) is to avoid escape for any characters.
For example, if this field is set to 0xc0000002, PPP sends characters 0x1f, 0x1e, and 0x01 as two-byte escape sequences.
Specify the control characters that cannot be successfully transmitted over a serial line. PPP sends these characters to the peer as 2-byte escape sequences instead.
The value of this field is a 32-bit hexadecimal number. Each bit represents a character to escape. The most significant bit represents character 0x1f, and the least significant bit represents character 0x00. Only characters 0x00 through 0x1f can be escaped. The default setting (that is, a blank field) is not to escape any characters.
For example, if this field is set to 0xc0000002, PPP sends characters 0x1f, 0x1e, and 0x01 as two-byte escape sequences.
Specify if you want to direct the PPP subsystem to negotiate the MRU with the peer.
Specify if you want to direct the PPP subsystem to negotiate asynchronous character maps with the peer.
Specify if you want to direct the PPP subsystem to support compression of the PPP protocol field. Selecting this option causes each transmitted datagram packet to be reduced by 1 byte.
Specify if you want to direct the PPP subsystem to support compression of the PPP address and control fields. Selecting this option causes a reduction of 2 bytes per frame sent.
Specify the interval in seconds between CHAP challenges. A CHAP challenge causes the authenticator to re-authenticate the PPP connection with the peer. Only the authenticator host uses this field. This value effects all connections to peers that use CHAP authentication during PPP connection. Changes do not take effect until the PPP subsystem is restarted.
A value of 0 is equivalent to no value. With a value of 0 or no value, CHAP challenges are not made after initial CHAP authentication.
Specify a decimal value that represents the maximum number of multilink attachments, both client and server, that can be active. This option allows multilink attachments. A multilink attachment is identified through a command line option, multilink, to /usr/sbin/pppattachd. Two examples are:
/usr/sbin/pppattachd server multilink 2>/dev/null
/usr/sbin/pppattachd tty2 client multilink connect
"pppdial -f dialog.ppp".
Specify a decimal value that represents the maximum receive reconstructed unit (MRRU), which is the maximum number of bytes that can be received by an upper layer protocol. This option affects multilink attachments.
Datagrams are fragmented across multiple physical links and subsequently reassembled into units of the specified MRRU size. The default value is 1500 bytes.
Specify the PPP subsystem telephone number for accessing the local system. Only one telephone number is needed. The value can be a maximum of 15 digits.
This option affects multilink attachments. This value is used to construct an endpoint discriminator, providing a unique identification of this system in multilink environments. You should use this option for multilink attachments. If you do not use it, the endpoint discriminator is not sent to the remote system.
Removes a single existing IP interface.
Specify the TCP/IP address of the current system for an interface.
Specify the TCP/IP address for the remote system. This address can be the start of a range of TCP/IP interface addresses.
Specify the number of interfaces that are configured beginning with the Starting Remote IP address. Specify 1 (one) if a single interface is desired. The range should not exceed the value specified for max server links in the lcp_config file.
Specify a 32-bit network mask in dotted decimal form (for example, 111.222.333.444).
Specify the TCP/IP address of the current system for an interface.
Specify the TCP/IP address for the remote system.
Specify a quoted string containing the command you want run to establish the connection with the authenticator host. Because you cannot place quotation characters within this string, you may want to provide the name of a shell script (in quotations) for this value. The /etc/ppp/dial_out.example file contains an example attachment shell script. If you were to modify this example and want to specify it as the demand command, you would enter "/etc/ppp/dial_out.example" as the demand command.
The attachment process should not become a daemon because this change causes rapid spawning. You can pass the nodaemon option to /usr/sbin/pppattachd to prevent the creation of a daemon process.
Specify the password for authenticating the peer with the authenticator host. For successful authentication, the corresponding passwords must match with the peer and the authenticator.
Specify when the PPP subsystem is to be started. Select one of the following options:
Start the PPP subsystem immediately and at every system startup. This option is the default.
Start the PPP subsystem immediately, but make no permanent changes to the system.
Start the PPP subsystem on the next system startup. The /etc/inittab file is modified.
Specify when the PPP subsystem is to be stopped. Select one of the following options:
Stop the PPP subsystem immediately and do not start the PPP subsystem upon system startup. This option is the default.
Stop the PPP subsystem immediately, but make no permanent changes to the system.
Do not start the PPP subsystem on the next system startup. The /etc/inittab file is modified.
Specify if you want the PPP subsystem to perform magic number negotiation.
