From 6027b0ed7d1791a363004ec5b77ec7e866fc8bc9 Mon Sep 17 00:00:00 2001 From: Roy Marples Date: Thu, 16 Apr 2009 23:47:23 +0000 Subject: [PATCH] Add a new init script - network This simply assigns static addresses and an optional default route. It's possible to add external commands as well, so to create a bonded interface. Hopefully we can add a few examples to satisfy most of the old net.lo, which is no longer installed into boot by default. --- conf.d/Makefile | 4 +- conf.d/Makefile.FreeBSD | 3 + conf.d/Makefile.Linux | 4 + conf.d/Makefile.NetBSD | 3 + conf.d/network.Linux | 10 ++ conf.d/network.in | 10 ++ init.d/Makefile | 4 +- init.d/network.in | 226 +++++++++++++++++++++++++++++++++++++++ runlevels/Makefile | 3 +- runlevels/Makefile.BSD | 2 +- runlevels/Makefile.Linux | 2 +- 11 files changed, 264 insertions(+), 7 deletions(-) create mode 100644 conf.d/network.Linux create mode 100644 conf.d/network.in create mode 100644 init.d/network.in diff --git a/conf.d/Makefile b/conf.d/Makefile index 5040ba27..9d0fc0d0 100644 --- a/conf.d/Makefile +++ b/conf.d/Makefile @@ -1,5 +1,7 @@ DIR= ${CONFDIR} -CONF= bootmisc fsck hostname local localmount net urandom +CONF= bootmisc fsck hostname local localmount network urandom + +CLEANFILES+= network MK= ../mk include ${MK}/os.mk diff --git a/conf.d/Makefile.FreeBSD b/conf.d/Makefile.FreeBSD index c43a1d4f..fb531e2f 100644 --- a/conf.d/Makefile.FreeBSD +++ b/conf.d/Makefile.FreeBSD @@ -1 +1,4 @@ CONF+= ipfw moused powerd rarpd savecore syscons + +network: + cp network.in network diff --git a/conf.d/Makefile.Linux b/conf.d/Makefile.Linux index 74679400..9e1ce9d8 100644 --- a/conf.d/Makefile.Linux +++ b/conf.d/Makefile.Linux @@ -1 +1,5 @@ CONF+= consolefont dmesg hwclock keymaps modules + +network: + cp network.in network + cat network.Linux >> network diff --git a/conf.d/Makefile.NetBSD b/conf.d/Makefile.NetBSD index 18a52cce..fd0be1ec 100644 --- a/conf.d/Makefile.NetBSD +++ b/conf.d/Makefile.NetBSD @@ -1 +1,4 @@ CONF+= moused rarpd savecore + +network: + cp network.in network diff --git a/conf.d/network.Linux b/conf.d/network.Linux new file mode 100644 index 00000000..9967301d --- /dev/null +++ b/conf.d/network.Linux @@ -0,0 +1,10 @@ +# ifconfig under Linux is not that powerful and doesn't easily handle +# multiple addresses +# On the other hand, ip (iproute2) is quite powerful and is also supported +# ip_eth0="192.168.0.10/24; 192.168.10.10/24" + +# Create a bonded interface +# interfaces="bond0" +# ifup_bond0="modprobe bonding; ifconfig bond0 up; ifenslave bond0 bge0" +# ifconfig_bond0="192.168.0.10/24" +# ifdown_bond0="rmmod bonding" diff --git a/conf.d/network.in b/conf.d/network.in new file mode 100644 index 00000000..2bb2b071 --- /dev/null +++ b/conf.d/network.in @@ -0,0 +1,10 @@ +# Assign static IP addresses and run custom scripts per interface +# Seperate commands with ; +# Prefix with ! to run a shell script +# ifconfig_eth0="up; 192.168.0.10 netmask 255.255.255.0; ! echo up" + +# You also have ifup_eth0 and ifdown_eth0 to run other commands when +# eth0 is started and stopped. +# Lastly, the interfaces variable pulls in virtual interfaces that cannot +# be automatically detected. + diff --git a/init.d/Makefile b/init.d/Makefile index fd2c87d1..d3c7cf1b 100644 --- a/init.d/Makefile +++ b/init.d/Makefile @@ -1,6 +1,6 @@ DIR= ${INITDIR} -SRCS= bootmisc.in fsck.in hostname.in local.in localmount.in \ - netmount.in root.in savecache.in swap.in sysctl.in urandom.in +SRCS= bootmisc.in fsck.in hostname.in local.in localmount.in netmount.in \ + network.in root.in savecache.in swap.in sysctl.in urandom.in BIN= ${OBJS} INSTALLAFTER= _installafter diff --git a/init.d/network.in b/init.d/network.in new file mode 100644 index 00000000..9b3fc285 --- /dev/null +++ b/init.d/network.in @@ -0,0 +1,226 @@ +#!@PREFIX@/sbin/runscript +# Copyright 2009 Roy Marples +# All rights reserved.
