Command

Synopsis

PPP <port> IDLE [secs]
PPP <port> IPCP <LOCAL | REMOTE> <ADDRESS | DNS> [ipaddr]
PPP <port> LCP <LOCAL | REMOTE> AUTH [PAP]
PPP <port> LCP <LOCAL | REMOTE> DEFAULT
PPP <port> LCP <LOCAL | REMOTE> MRU [mru]
PPP <port> LOG [0-255]
PPP <port> PAP <USER> [username password]

Description

Point to Point Protocol (PPP) is a protocol suite intended for use over simple links which transport packets between two peers, such as an RS232 link. The PPP commands are used to configure the system.

Options

The IDLE subcommand is used to display or set the PPP link inactivity timer, which disconnects the link after a period of inactivity. The argument is in seconds.

The IPCP subcommands control the IPCP (IP Control Protocol) parameters for each end of the link. ADDRESS specifies the IP addresses used for the link, and DNS specifies the IP addresses of the Domain Name Server.

The LCP subcommands control the LCP (Link Control Protocol) parameters for each end of the link. AUTH specifies the authentication protocol (if any) which the link will use. The only authentication protocol currently supported is PAP. The MRU command specifies the Maximum Receive Unit, i.e. the largest datagram the host is prepared to accept. The limits are 128 and 4096. DEFAULT restores the default LCP parameters which all hosts understand.

The LOG subcommand displays or sets the PPP logging level, which controls how much diagnostic detail is recorded in the PPLOG.TXT file. The argument is as follows:

	0       No logging
	1       PPP start/stop/timeout events
	2       As 1, plus layer up/down events
	3       As 2, plus layer start/stop events
	4       as 3, plus option accept/reject events
	5       as 4, plus hexdump of configuration packets

The PAP subcommand displays or sets PAP (Password Authentication Protocol) parameters. At present the only parameter is USER, which specifies the username and password for PAP login.

Examples

PPP 1 IDLE 300
PPP 1 IPCP LOCAL ADDRESS 62.31.45.67
PPP 3 LCP LOCAL AUTH PAP
PPP 3 LCP LOCAL DEFAULT
PPP 3 LCP LOCAL MRU 1500
PPP 3 LOG 3
PPP 1 PAP USER g8pzt zedfrgc

Notes

When used from the command line, or with a BOOTCMDS.SYS file, the first argument must be a port number. However, PPP commands used within PPPHOST and dialler scripts *do not* include a port number, because Xrouter knows which port is executing the script.

e.g. at the command line: PPP 3 IDLE 300
in a dialler script: PPP IDLE 300

You are advised against using the higher PPP LOG levels other than on a temporary basis because they can create very large logfiles.

Availability

Sysop-only.
