sppptun(1M) System Administration Commands sppptun(1M)NAMEsppptun - PPP tunneling driver utility
SYNOPSISsppptun plumb
sppptun plumb protocol device
sppptun unplumb interface
sppptun query
DESCRIPTION
The sppptun utility is used to configure and query the Solaris PPP tun‐
neling device driver, /dev/sppptun. Currently, only PPP over Ethernet
(PPPoE) is supported, so the plumb and unplumb arguments are used to
specify Ethernet interfaces that are to be used for PPPoE, and the
query option lists the plumbed interfaces.
The use of sppptun to add interfaces is similar to the use of ifcon‐
fig(1M) to add interfaces to IP. The plumbing is done once for each
interface, preferably at system start-up time, and is not normally
manipulated on a running system. If multiple instances of PPP are run
over a single interface, they share the plumbing to that interface.
Plumbing for each session is not required (and not possible for PPPoE).
The proper way to plumb interfaces for PPPoE is to list the interfaces,
one per line, in the /etc/ppp/pppoe.if file.
USAGEsppptun plumb
When specified with no additional arguments, the plumb argument
lists the protocols that are supported by the utility. These are
the strings that are used as the protocol argument below.
sppptun plumb protocol device
This plumbs a new interface into the driver. The protocol parameter
is pppoe for the PPP-carrying "Session Stage" connection or pppoed
for the PPPoE "Discovery Stage" connection. Both connections must
be present for each Ethernet interface that is to be used for
PPPoE. The device parameter is the path name of the Ethernet
interface to use (use ifconfig(1M) to list available devices). If
the path begins with /dev/, then this portion may be omitted.
sppptun unplumb interface
This removes an existing interface from the driver and terminates
any PPP sessions that were using the interface. The interface
parameter is the name of the interface as reported when the inter‐
face was plumbed.
sppptun query
Displays the canonical names of all interfaces plumbed into the
/dev/sppptun device driver.
EXAMPLES
Example 1 Setting up to Use PPPoE on hme0
Plumb the hme0 interface.
# sppptun plumb pppoed hme0
hme0:pppoed
# sppptun plumb pppoe hme0
hme0:pppoe
Remove the hme0 interface.
# sppptun unplumb hme0:pppoed
# sppptun unplumb hme0:pppoe
Example 2 Script to Remove All Plumbed Interfaces
#!/bin/sh
for intf in `sppptun query`
do
sppptun unplumb $intf
done
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 One or more errors occurred.
