Introduction to Netplug
Netplug is a Linux daemon that brings up/down network interfaces in response to network cables being plugged in and out. This application is mostly useful for a laptop or computer (used for lan parties?) that is often relocated to different LANs.
The netplugd rc script shared below replaces the clfs-bootscripts network script. If you remove the network script and symlinks in the rc#.d directories, and later decide you want them, then merely reinstall from the clfs-bootscripts.
Dependencies
Required
- Dhcpcd
- or other dhcp client
Configuration Information
This package does not use a configure script. Any additional configuration must be made within the Makefile.
Non-Multilib
Much of this, including the patches were ripped from the Gentoo ebuild. These instructions did successfully install the application onto a pentium-m based x86 laptop.
Modify the Makefile:
remove=" -ggdb3 " [[ " ${CFLAGS} " == *" -O"[0-9]" "* ]] && remove="${remove}-O3 " sed -i -e "s/${remove}/ /" Makefile sed -i '/bk_root/,$d' Makefile
Apply patches:
patch -Np0 -i ../netplug-1.2.9-gcc4-1.patch patch -Np1 -i ../netplug-1.2.9-remove-nest-1.patch patch -Np1 -i ../netplug-1.2.9-ignore-wireless-1.patch
Compile and install the package:
make make install
