About the changes, most of the documentation is ancient. from http://www.policyrouting.org/iproute2.doc.html Obtaining & Compiling IPROUTE2 The ip utility is just one of the utilities in the IPROUTE2 utility package from Alexey. The primary FTP site was located in Russia at ftp://ftp.inr.ac.ru/ip-routing/ but is no longer running. The most complete mirror is located at http://www.linuxgrill.com/anonymous/iproute2/ with the newest OSDL source code located within the http://www.linuxgrill.com/anonymous/iproute2/NEW-OSDL/ directory. We will assume that you have obtained the latest package usually called iproute2-current symlinked to the latest dated version. The version we primarily cover here is the 1999-06-30 version of IPROUTE2. I cloned the git repo for iproute2 and looked at the man page included with the distrubution, this it the top line [ TH IP 8 "17 January 2002" "iproute2" "Linux" ]. Slightly different than the one in the man ip shows. After several hours of reading it appears to be necessary to use the -4 option to read and ipv4 address. It also seems to make a difference whether your hooked up to a system somewhere, say a business or university, or a single home computer nated behind a satellite internet connection with the name resolver parked in Maryland and no knowledge of your home system. This may not be directly to the point about the changes, but leaves you wondering if any body really knows? About my rant from last night. The way I originally set my system up worked but broke gai configuration This is now # /etc/hosts: static lookup table for host names #<ip-address> <hostname.domain.org> <hostname> 127.0.0.1 localhost.localdomain localhost 192.168.0.3 arwen.localdomain arwen 192.168.0.5 gandalf.localdomain gandalf #::1 localhost.localdomain localhost gandalf If you set it up this way you can talk to each other, but it tends to screw other things up. # /etc/hosts: static lookup table for host names #<ip-address> <hostname.domain.org> <hostname> 127.0.0.1 localhost.localdomain localhost gandalf 192.168.0.3 arwen.localdomain arwen 192.168.0.5 gandalf.localdomain gandalf localhost #::1 localhost.localdomain localhost gandalf My bad.
