pppoec(1M) System Administration Commands pppoec(1M)NAMEpppoec - PPPoE chat utility
SYNOPSISpppoec [-omillisecs] [-smillisecs] [-v] device [service [
[except]server... [only]]]
pppoec [-omillisecs] [-v] -i [device]
DESCRIPTION
The pppoec utility implements the client-side negotiation of PPPoE. It
is intended to be used with the pppd(1M) connect option, in the same
manner as the chat(1M) utility is used for asynchronous dial-up PPP.
When given with the -i flag, pppoec sends out a broadcast query on the
given interface named by the device parameter. You can specify no other
arguments in this mode. All responding PPPoE servers and the offered
services are displayed on standard output.
Otherwise, when given without the -i flag, pppoec does the full PPPoE
client-side negotiation. The device parameter is the intended Ethernet
interface, and must already be plumbed with sppptun(1M). The optional
service parameter specifies a particular service desired; other offered
services will be ignored. The optional server parameter specifies a
specific server desired. You can specify server as an Ethernet address
in the usual x:x:x:x:x:x format (with "*" in any of the six byte posi‐
tions interpreted to mean "any"), or as a symbolic name resolved
through /etc/ethers (or NIS), or as a PPPoE access concentrator name.
The sense of the match (true or false) can be inverted by specifying
the keyword except before this string. This parameter can be specified
more than once, and the first match is taken.
If you specify the server parameter, then the selected servers become
"preferred." If no preferred server responds, then the first responding
server is used instead. To exclude non-matching servers entirely,
append the keyword only.
OPTIONS
The following options are supported:
-i Sends out broadcast query over interface specified by
device.
-o Sets the initial wait time in milliseconds for PADO
from the server before PADI is retried. The default is
500 milliseconds for normal operation, or 3000 mil‐
liseconds (3 seconds) for inquiry (-i) mode.
-s Sets the initial wait time in milliseconds for PADS
from the server before PADR is retried. The default is
2000 milliseconds (2 seconds).
-v Displays verbose progress messages, including all PPPoE
messages sent, and all state machine transitions.
You normally do not need to adjust the parameters set with -o and -s.
They are provided for coping with unusually slow servers.
OPERANDS
The following operands are supported:
device plumbed Ethernet interface
server preferred server or, if you specify only, the
specified server
service desired service; other available services are
ignored
EXAMPLES
Example 1: Connecting to Any Service on hme0
The following command enables you to connect to any PPPoE service on
hme0:
# /usr/bin/pppd sppptun plugin pppoe.so connect "/usr/lib/inet/pppoec hme0" debug
Often, a command such as the preceding is specified in an
/etc/ppp/peers file instead. For example, enter the following in
/etc/ppp/peers/myisp:
sppptun
plugin pppoe.so
connect "/usr/lib/inet/pppoec hme0"
debug
To invoke the PPP connection described in the file, enter:
% /usr/bin/pppd call myisp
Note that, because the /etc/ppp/peers files are considered privileged
by pppd, you need not be root to invoke the preceding command.
Example 2: Connecting to a Particular Service
A more complex example: on hme0, connect to only the internet service
offered by PPPoE servers with access concentrator name isp, but not to
any Ethernet addresses starting with 40:0:1a.
# /usr/lib/inet/pppoec hme0 internet except 40:0:1a:*:*:* isp only
Note that the except 40:0:1a:*:*:* filter must come before isp, because
the filters are first-match.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.

DIAGNOSTICS
Error messages are written to standard error, which is normally redi‐
rected by pppd to /etc/ppp/connect-errors. The errors can also be redi‐
rected to pppd's standard output by using the updetach option.
If you specify the -v, verbose progress messages are displayed, includ‐
ing all PPPoE messages sent, and all state machine transitions. Speci‐
fying the updetach or nodetach pppd option is helpful when using ver‐
bose mode.
