2178	ifcfg script (package IPRoute2) needs arping and rdisc to work properly, but these applications are not in the LFS	Gabriel Negreira Barbosa	bdubbs@…	"I noticed that ifcfg script, ""member"" of IPRoute-2 package, needs arping, but arping is not built in LFS. Additionally, rdisc is used by ifcfg too.[[BR]]

This script is not used in the book (procedures and LFS bootscripts), so it doesn't affect the compilation of LFS. But this is a ""broken application"" in LFS, and if someone needs to use it, probably it won't work properly.[[BR]]

I think this need to be fixed in order to maintain the system stable and with no broken applications.[[BR]]

Both arping and rdisc are in the iputils package (http://www.linux-foundation.org/en/Net:Iputils / http://www.skbuff.net/iputils), so I think the best solution is to install at least these 2 iputils' applications needed by ifcfg script: arping and rdisc. This could be in 6.41 section (IPRoute2) because iputils will be installed just to make ifcfg run properly.[[BR]]

IPRoute's ip command can be used to manage IP address, but using ifcfg (that uses ip command internally) for this purpose can be a much better ifconfig's replacement, because: ""It not only adds addresses, but also carries out Duplicate Address Detection, sends unsolicited ARP to update the caches of other hosts sharing the interface, adds some control routes and restarts Router Discovery when it is necessary."" (IPRoute2-2.6.20-079313 documentation: ip-cref.tex file)[[BR]]

I didn't built LFS-SVN, but quickly digging into this version of the book, I noticed that the ""problem"" described here also happens."	defect	closed	normal	6.4	Book	6.3	minor	fixed
