The 'ppp' commands are used for Point to Point Protocol
interfaces.
This implementation of PPP is designed to be as complete as
possible. Because of this, the number of options can be rather
daunting. However, a typical PPP configuration might include the
following commands:
attach asy 0x3f8 4 ppp pp0 4096 1500 9600
dial pp0 30 <host> 3 dialer.pp0
#
ppp pp0 lcp local accm 0
ppp pp0 lcp local compress address on
ppp pp0 lcp local compress protocol on
ppp pp0 lcp local magic on
ppp pp0 lcp open active
#
ppp pp0 ipcp local compress tcp 16 1
ppp pp0 ipcp open active
#
route add default pp0
_________________________________________________________________
ppp <interface>
_________________________________________________________________
Display the status of the PPP interface.
The following commands are used for the LCP (Link Control
Protocol) configuration.
_________________________________________________________________
ppp <interface> lcp close
_________________________________________________________________
Shutdown the PPP interface.
_________________________________________________________________
ppp <interface> lcp local ...
_________________________________________________________________
The 'lcp local' commands control the configuration of the local
side of the link. If an option is specified, the parameters will
be used as the initial values in configuration requests. If not
specified, that option will not be requested.
For each of these options, the 'allow' parameter will permit the
remote host to include that option in its response, even when the
option is not included in the request. By default, all options
are allowed.
_________________________________________________________________
ppp <interface> lcp local accm [ <bitmap> | allow [on | off] ]
_________________________________________________________________
Display or set the ACCM (Async Control Character Map). The
default is 0xffffffff.
_________________________________________________________________
ppp <interface> lcp local authenticate [ pap | none | allow
[on | off] ]
_________________________________________________________________
Display or set the authentication protocol. The default is none.
_________________________________________________________________
ppp <interface> lcp local compress address/control
[ on | off | allow [on | off] ]
_________________________________________________________________
Display or set the option to compress the address and control
fields of the PPP HLDC-like header. This is generally desirable
for slow asynchronous links, and undesirable for fast or
synchronous links. The default is off.
_________________________________________________________________
ppp <interface> lcp local compress protocol
[ on | off | allow [on|off]]
_________________________________________________________________
Display or set the option to compress the protocol field of the
PPP HLDC-like header. This is generally desirable for slow
asynchronous links, and undesirable for fast or synchronous
links. The default is off.
_________________________________________________________________
ppp <interface> lcp local magic [ on | off | <value> | allow
[on|off] ]
_________________________________________________________________
Display or set the initial Magic Number. The default is off
(zero).
_________________________________________________________________
ppp <interface> lcp local mru [ <size> | allow [on | off] ]
_________________________________________________________________
Display or set the Maximum Receive Unit. The default is 1500.
_________________________________________________________________
ppp <interface> lcp local default
_________________________________________________________________
Reset the options to their default values.
_________________________________________________________________
ppp <interface> lcp open active | passive
_________________________________________________________________
Wait for the physical layer to come up. If 'active', initiate
configuration negotiation. If 'passive', wait for configuration
negotiation from the remote.
_________________________________________________________________
ppp <interface> lcp remote ...
_________________________________________________________________
The 'lcp remote' commands control the configuration of the remote
side of the link. The options are identical to those of the
local side.
If an option is specified, the parameters will be used in
responses to the remote's configuration requests.
If not specified, that option will be accepted if it is allowed.
For each of these options, the 'allow' parameter will permit the
remote to specify that option in its request.
By default, all options are allowed.
_________________________________________________________________
ppp <interface> lcp timeout [<seconds>] Default: 3
_________________________________________________________________
Display or set the interval to wait between configuration or
termination attempts.
_________________________________________________________________
ppp <interface> lcp try ...
_________________________________________________________________
The 'lcp try' commands are used for the various counters.
_________________________________________________________________
ppp <interface> lcp try configure [<count>] Default: 10
_________________________________________________________________
Display or set the number of configuration requests sent.
_________________________________________________________________
ppp <interface> lcp try failure [<count>] Default: 5
_________________________________________________________________
Display or set the number of bad configuration requests allowed
from the remote.
_________________________________________________________________
ppp <interface> lcp try terminate [<count>] Default: 2
_________________________________________________________________
Display or set the number of termination requests sent before
shutdown.
_________________________________________________________________
ppp <interface> ipcp ...
_________________________________________________________________
The 'ipcp' commands are used for the Internet Protocol Control
Protocol configuration.
The 'close', 'open', 'timeout' and 'try' sub-commands are
identical to the LCP (described above).
_________________________________________________________________
ppp <interface> ipcp local ...
_________________________________________________________________
The 'ipcp local' commands control the configuration of the local
side of the link. If an option is specified, the parameters will
be used as the initial values in configuration requests. If not
specified, that option will not be requested.
For each of these options, the 'allow' parameter will permit the
remote to include that option in its response, even when the
option is not included in the request. By default, all options
are allowed.
_________________________________________________________________
ppp <interface> ipcp local address [ <hostid> | allow
[on | off] ]
_________________________________________________________________
Display or set the local address for negotiation purposes. If an
address of 0 is specified, the other side of the link will supply
the address. By default, no addresses are negotiated.
_________________________________________________________________
ppp <interface> ipcp local compress [ tcp <slots>
[<flag>] | none | allow [on | off] ]
_________________________________________________________________
Display or set the compression protocol. The default is none.
The tcp <slots> specifies the number of "conversation" slots,
which must be 1 to 255. (This may be limited at compilation time
to a smaller number.) A good choice is in the range 4 to 16.
The tcp <flag> is 0 (don't compress the slot number) or 1 (OK to
compress the slot number). KA9Q NOS can handle compressed slot
numbers, so the default is 1.
_________________________________________________________________
ppp <interface> ipcp remote ...
_________________________________________________________________
The 'ipcp remote' commands control the configuration of the
remote side of the link. The options are identical to those of
the local side. If an option is specified, the parameters will
be used in responses to the remote's configuration requests. If
not specified, that option will be accepted if it is allowed.
For each of these options, the 'allow' parameter will permit the
remote to specify that option in its request. By default, all
options are allowed.
_________________________________________________________________
ppp <iface> pap ...
_________________________________________________________________
The 'pap' commands are used for the Password Authentication
Protocol configuration.
The 'timeout' and 'try' sub-commands are identical to the LCP
(described above). However, the terminate counter is unused.
_________________________________________________________________
ppp <interface> pap user [ <username> [<password>] ]
_________________________________________________________________
Display or set the <username>.
The <password> may also be set, but not displayed.
When <username> is specified, but no password is supplied, the
FTPUSERS file is searched for the password. When a username-
password pair is unknown or rejected, a session will appear at
the console to prompt for a new username-password.
_________________________________________________________________
ppp <interface> trace [<flags>]
_________________________________________________________________
Display or set the flags that control the logging of information
during PPP link configuration.
The flag values are:
0: No trace
1: Basic trace
2: General trace
Values greater than 2 are usually not compiled, and are described
in the appropriate source files where they are defined.
