If you do not have + Sun's WorkShop compiler, configure will attempt to use 'gcc'. If + this is found and you have a 64 bit kernel, it will check that gcc + accepts the "-m64" option, which is required to build kernel + modules. + + You should not have to edit the Makefiles for most ordinary cases. 2.

This + version comes with the standard Solaris software distribution and is + supported by Sun. It is fully tested in 64-bit and SMP modes, and + with bundled and unbundled synchronous drivers. Solaris 8 10/01 + (Update 6) and later includes integrated PPPoE client and server + support, with kernel-resident data handling. See pppd(1M). + + The feature is part of the regular full installation, and is + provided by these packages: + + SUNWpppd - 32-bit mode kernel drivers + SUNWpppdr - root-resident /etc/ppp config samples + SUNWpppdu - /usr/bin/pppd itself, plus chat + SUNWpppdx - 64-bit mode kernel drivers + SUNWpppdt - PPPoE support + SUNWpppg - GPL'd optional 'pppdump' and plugins + SUNWpppgS - Source for GPL'd optional features + + Use the open source version of pppd if you wish to recompile to add + new features or to experiment with the code. Production systems, + however, should run the Sun-supplied version, if at all possible. + + You can run both versions on a single system if you wish. The + Solaris PPP 4.0 interfaces are named "spppN," while this open source + version names its interfaces as "pppN". The STREAMS modules are + similarly separated. The Sun-supplied pppd lives in /usr/bin/pppd, + while the open source version installs (by default) in + /usr/local/bin/pppd. + +Dynamic STREAMS Re-Plumbing Support. +************************************ + + Solaris 8 (and later) includes dynamic re-plumbing support. With + this feature, modules below ip can be inserted, or removed, without + having the ip stream be unplumbed, and re-plumbed again. All state + in ip for the interface will be preserved as modules are added or + removed. Users can install (or upgrade) modules such as firewall, + bandwidth manager, cache manager, tunneling, etc., without shutting + the interface 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 have been + done on Solaris 7 through 9. Only IPv4 and IPv6 packets will be sent + up to stream(s) marked as promiscuous (i.e., those used by snoop). + + Users will be able to see the packets on the ppp interface by, for + example: -If your system normally has only one network interface, the default -Solaris 2 system startup scripts will disable IP forwarding in the IP -kernel module.

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 work 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.
