Solaris 2 are in the svr4 directory (and use some code from the
modules directory).
-This version has been tested under Solaris 2.6.
-
NOTE: Although the kernel driver and modules have been designed to
operate correctly on SMP systems, they have not been extensively
tested on SMP machines. Some users of SMP Solaris x86 systems have
/usr/sbin/ndd -set /dev/ip ip_forwarding 1
See the man page for ip(7p) for details.
+
+Dynamic STREAMS Re-Plumbing Support.
+************************************
+
+Solaris 8 includes dynamic re-plumbing support. With this, modules
+below ip can be inserted, or removed, without having the ip stream be
+unplumbed, and re-plumbed again. All states in ip for an interface
+will therefore now be preserved. Users can install (or upgrade)
+modules like firewall, bandwidth manager, cache manager, tunneling,
+etc., without shutting the machine down.
+
+To support this, ppp driver now uses /dev/udp instead of /dev/ip for
+the ip stream. The interface stream (where ip module pushed on top of
+ppp) is then I_PLINK'ed below the ip stream. /dev/udp is used because
+STREAMS will not let a driver be PLINK'ed under itself, and /dev/ip is
+typically the driver at the bottom of the tunneling interfaces
+stream. The mux ids of the ip streams are then added using
+SIOCSxIFMUXID ioctl.
+
+Users will be able to see the modules on the interface stream by, for
+example:
+
+ pikapon% ifconfig ppp modlist
+ 0 ip
+ 1 ppp
+
+Or arbitrarily if bandwidth manager and firewall modules are installed:
+
+ pikapon% ifconfig hme0 modlist
+ 0 arp
+ 1 ip
+ 2 ipqos
+ 3 firewall
+ 4 hme
+
+Snoop Support.
+**************
+
+This version includes support for /usr/sbin/snoop. Tests has been done
+on both Solaris 7 and 8. Only IPv4 and IPv6 packets will be sent up to
+stream(s) marked as promiscuous, e.g, snoop et al.
+
+Users will be able to see the packets on the ppp interface by, for example:
+
+ snoop -d ppp0
+
+See the man page for snoop(1M) for details.
+
+IPv6 Support.
+*************
+
+This is for Solaris 8 and later.
+
+This version has been tested under Solaris 8 running IPv6. As of now,
+interoperability testing has only been done between Solaris machines
+in terms of the IPV6 NCP. An additional command line option for the
+pppd daemon has been added: ipv6cp-use-persistent.
+
+By default, compilation for IPv6 support is not enabled. Uncomment
+the necessary lines in pppd/Makefile.sol2 to enable it. Once done, the
+quickest way to get IPv6 running is to add the following somewhere in
+the command line option:
+
+ +ipv6 ipv6cp-use-persistent
+
+The persistent id for the link-local address was added to conform to
+RFC 2472; such that if there's an EUI-48 available, use that to make
+up the EUI-64. As of now, the Solaris implementation extracts the
+EUI-48 id from the Ethernet's MAC address (the ethernet interface
+needs to be up). Future works might support other ways of obtaining a
+unique yet persistent id, such as EEPROM serial numbers, etc.
+
+There need not be any up/down scripts for ipv6, e.g. /etc/ppp/ipv6-up
+or /etc/ppp/ipv6-down, to trigger IPv6 neighbor discovery for auto
+configuration and routing. The in.ndpd daemon will perform all of the
+necessary jobs in the background. /etc/inet/ndpd.conf can be further
+customized to enable the machine as an IPv6 router. See the man page
+for in.ndpd(1M) and ndpd.conf(4) for details.
+
+Below is a sample output of "ifconfig -a" with persistent link-local
+address. Note the UNNUMBERED flag is set because hme0 and ppp0 both
+have identical link-local IPv6 addresses:
+
+lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
+ inet 127.0.0.1 netmask ff000000
+hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2

+hme0:3: flags=2080841<UP,RUNNING,MULTICAST,ADDRCONF,IPv6> mtu 1500 index 2
+ inet6 2::56:a00:20ff:fe8d:38c1/64
+ppp0: flags=10008d1<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST,IPv4> mtu 1500 index 12
+ inet 172.16.1.1 --> 172.16.1.2 netmask ffffff00
+ppp0: flags=2202851<UP,POINTOPOINT,RUNNING,MULTICAST,UNNUMBERED,NONUD,IPv6> mtu 1500 index 12
+ inet6 fe80::a00:20ff:fe8d:38c1/10 --> fe80::a00:20ff:fe7a:24fb
+
+Note also that a plumbed ipv6 interface stream will exist throughout
+the entire PPP session in the case where the peer rejects IPV6CP,
+which further causes the interface state to stay down. Unplumbing will
+happen when the daemon exits. This is done by design and is not a bug.
+
+64-bit Support.
+***************
+
+This version has been tested under Solaris 7 (and Solaris 8 ) in both
+32- and 64-bits environments (Ultra class machines). Installing the
+package by executing "make install" will result in additional files
+residing in /kernel/drv/sparcv9 and /kernel/strmod/sparcv9
+subdirectories.
+
+64-bit modules and driver have been compiled and tested using Sun's cc.
+
+Synchronous Serial Support.
+***************************
+
+This version has working but limited support for the on-board
+synchronous HDLC interfaces. It has been tested with the /dev/se_hdlc
+and /dev/zsh drivers. Synchronous mode was tested with a Cisco
+router.
+
+There ppp daemon does not directly support controlling the serial
+interface. It relies on the /usr/sbin/syncinit command to initialize
+HDLC mode and clocking.
+
+Some bugs remain: large sized frames are not sent/received properly,
+and may be related to the IP mtu. This may be due to bugs in pppd
+itself, bugs in Solaris or the serial drivers. The /dev/zsh driver
+seems more larger and can send/receive larger frames than the
+/dev/se_hdlc driver. There is a confirmed bug with NRZ/NRZI mode in
+the /dev/se_hdlc driver, and Solaris patch 104596-11 is needed to
+correct it. (However this patch seems to introduce other serial
+problems. If you don't apply the patch, the workaround is to change
+the nrzi mode to yes or no, whichever works)
+
+How to start pppd with synchronous support:
+
+#!/bin/sh
+
+local=1.1.1.1 # your ip address here
+baud=38400 # needed, but ignored by serial driver
+
+# Change to the correct serial driver/port
+#dev=/dev/zsh0
+dev=/dev/se_hdlc0
+
+# Change the driver, nrzi mode, speed and clocking to match your setup
+# This configuration is for external clocking from the DCE
+connect="syncinit se_hdlc0 nrzi=no speed=64000 txc=rxc rxc=rxc"
+
+/usr/sbin/pppd $dev sync $baud novj noauth $local: connect "$connect"
