1 This file describes the installation process for ppp-2.4 on systems
2 running Solaris. The Solaris and SVR4 ports share a lot of code but
3 are not identical. The STREAMS kernel modules and driver for Solaris
4 are in the solaris directory (and use some code from the modules
7 NOTE: Although the kernel driver and modules have been designed to
8 operate correctly on SMP systems, they have not been extensively
9 tested on SMP machines. Some users of SMP Solaris x86 systems have
10 reported system problems apparently linked to the use of previous
11 versions of this software. I believe these problems have been fixed.
17 1. Run the configure script and make the user-level programs and the
23 The configure script will automatically find Sun's cc if it's in
24 the standard location (/opt/SUNWspro/bin/cc). If you do not have
25 Sun's WorkShop compiler, configure will attempt to use 'gcc'. If
26 this is found and you have a 64 bit kernel, it will check that gcc
27 accepts the "-m64" option, which is required to build kernel
30 You should not have to edit the Makefiles for most ordinary cases.
32 2. Install the programs and kernel modules: as root, do
36 This installs pppd, chat and pppstats in /usr/local/bin and the
37 kernel modules in /kernel/drv and /kernel/strmod, and creates the
38 /etc/ppp directory and populates it with default configuration
39 files. You can change the installation directories by editing
40 solaris/Makedefs. If you have a 64 bit kernel, the 64-bit drivers
41 are installed in /kernel/drv/sparcv9 and /kernel/strmod/sparcv9.
43 If your system normally has only one network interface at boot
44 time, the default Solaris system startup scripts will disable IP
45 forwarding in the IP kernel module. This will prevent the remote
46 machine from using the local machine as a gateway to access other
47 hosts. The solution is to create an /etc/ppp/ip-up script
48 containing something like this:
51 /usr/sbin/ndd -set /dev/ip ip_forwarding 1
53 See the man page for ip(7p) for details.
58 Solaris 8 07/01 (Update 5) and later have an integrated version of
59 pppd, known as "Solaris PPP 4.0," and is based on ppp-2.4.0. This
60 version comes with the standard Solaris software distribution and is
61 supported by Sun. It is fully tested in 64-bit and SMP modes, and
62 with bundled and unbundled synchronous drivers. Solaris 8 10/01
63 (Update 6) and later includes integrated PPPoE client and server
64 support, with kernel-resident data handling. See pppd(1M).
66 The feature is part of the regular full installation, and is
67 provided by these packages:
69 SUNWpppd - 32-bit mode kernel drivers
70 SUNWpppdr - root-resident /etc/ppp config samples
71 SUNWpppdu - /usr/bin/pppd itself, plus chat
72 SUNWpppdx - 64-bit mode kernel drivers
73 SUNWpppdt - PPPoE support
74 SUNWpppg - GPL'd optional 'pppdump' and plugins
75 SUNWpppgS - Source for GPL'd optional features
77 Use the open source version of pppd if you wish to recompile to add
78 new features or to experiment with the code. Production systems,
79 however, should run the Sun-supplied version, if at all possible.
81 You can run both versions on a single system if you wish. The
82 Solaris PPP 4.0 interfaces are named "spppN," while this open source
83 version names its interfaces as "pppN". The STREAMS modules are
84 similarly separated. The Sun-supplied pppd lives in /usr/bin/pppd,
85 while the open source version installs (by default) in
88 Dynamic STREAMS Re-Plumbing Support.
89 ************************************
91 Solaris 8 (and later) includes dynamic re-plumbing support. With
92 this feature, modules below ip can be inserted, or removed, without
93 having the ip stream be unplumbed, and re-plumbed again. All state
94 in ip for the interface will be preserved as modules are added or
95 removed. Users can install (or upgrade) modules such as firewall,
96 bandwidth manager, cache manager, tunneling, etc., without shutting
99 To support this, ppp driver now uses /dev/udp instead of /dev/ip for
100 the ip stream. The interface stream (where ip module pushed on top
101 of ppp) is then I_PLINK'ed below the ip stream. /dev/udp is used
102 because STREAMS will not let a driver be PLINK'ed under itself, and
103 /dev/ip is typically the driver at the bottom of the tunneling
104 interfaces stream. The mux ids of the ip streams are then added
105 using SIOCSxIFMUXID ioctl.
107 Users will be able to see the modules on the interface stream by,
110 pikapon# ifconfig ppp modlist
114 Or arbitrarily if bandwidth manager and firewall modules are installed:
116 pikapon# ifconfig hme0 modlist
126 This version includes support for /usr/sbin/snoop. Tests have been
127 done on Solaris 7 through 9. Only IPv4 and IPv6 packets will be sent
128 up to stream(s) marked as promiscuous (i.e., those used by snoop).
130 Users will be able to see the packets on the ppp interface by, for
135 See the man page for snoop(1M) for details.
140 This is for Solaris 8 and later.
142 This version has been tested under Solaris 8 and 9 running IPv6.
143 Interoperability testing has only been done between Solaris machines
144 in terms of the IPV6 NCP. An additional command line option for the
145 pppd daemon has been added: ipv6cp-use-persistent.
147 By default, compilation for IPv6 support is not enabled. Uncomment
148 the necessary lines in pppd/Makefile.sol2 to enable it. Once done,
149 the quickest way to get IPv6 running is to add the following
150 somewhere in the command line option:
152 +ipv6 ipv6cp-use-persistent
154 The persistent id for the link-local address was added to conform to
155 RFC 2472; such that if there's an EUI-48 available, use that to make
156 up the EUI-64. As of now, the Solaris implementation extracts the
157 EUI-48 id from the Ethernet's MAC address (the ethernet interface
158 needs to be up). Future work might support other ways of obtaining
159 a unique yet persistent id, such as EEPROM serial numbers, etc.
161 There need not be any up/down scripts for ipv6,
162 e.g. /etc/ppp/ipv6-up or /etc/ppp/ipv6-down, to trigger IPv6
163 neighbor discovery for auto configuration and routing. The in.ndpd
164 daemon will perform all of the necessary jobs in the
165 background. /etc/inet/ndpd.conf can be further customized to enable
166 the machine as an IPv6 router. See the man page for in.ndpd(1M) and
167 ndpd.conf(4) for details.
169 Below is a sample output of "ifconfig -a" with persistent link-local
170 address. Note the UNNUMBERED flag is set because hme0 and ppp0 both
171 have identical link-local IPv6 addresses:

194 Note also that a plumbed ipv6 interface stream will exist throughout
195 the entire PPP session in the case where the peer rejects IPV6CP,
196 which further causes the interface state to stay down. Unplumbing
197 will happen when the daemon exits. This is done by design and is not
203 This version has been tested under Solaris 7 through 9 in both 32-
204 and 64-bit environments (Ultra class machines). Installing the
205 package by executing "make install" will result in additional files
206 residing in /kernel/drv/sparcv9 and /kernel/strmod/sparcv9
209 64-bit modules and driver have been compiled and tested using Sun's
212 Synchronous Serial Support.
213 ***************************
215 This version has working but limited support for the on-board
216 synchronous HDLC interfaces. It has been tested with the
217 /dev/se_hdlc, /dev/zsh, HSI/S, and HSI/P drivers. Synchronous mode
218 was tested with a Cisco router.
220 The ppp daemon does not directly support controlling the serial
221 interface. It relies on the /usr/sbin/syncinit command to
222 initialize HDLC mode and clocking.
224 There is a confirmed bug with NRZ/NRZI mode in the /dev/se_hdlc
225 driver, and Solaris patch 104596-11 is needed to correct it.
226 (However this patch seems to introduce other serial problems. If
227 you don't apply the patch, the workaround is to change the nrzi mode
228 to yes or no, whichever works.)
230 How to start pppd with synchronous support:
234 local=1.1.1.1 # your ip address here
235 baud=38400 # needed, but ignored by serial driver
237 # Change to the correct serial driver/port
241 # Change the driver, nrzi mode, speed and clocking to match
243 # This configuration is for external clocking from the DCE
244 connect="syncinit se_hdlc0 nrzi=no speed=64000 txc=rxc rxc=rxc"
246 /usr/sbin/pppd $dev sync $baud novj noauth $local: connect "$connect"
