One snag in that post MadeInGermany.

Hosts that are a substring of others will cause mismatch with grep (eg DEV and DEV01)

Last edited by Chubler_XL; 06-02-2013 at 05:49 PM.. Reason: Removed statement about ping exit code - seems to set error condition if no packets received

NAME
ip-token - tokenized interface identifier support SYNOPSIS
ip token { COMMAND | help } ip token set TOKEN dev DEV ip token del dev DEV ip token get [ dev DEV ] ip token [ list ] DESCRIPTION
IPv6 tokenized interface identifier support is used for assigning well-known host-part addresses to nodes whilst still obtaining a global network prefix from Router advertisements. The primary target for tokenized identifiers are server platforms where addresses are usually manually configured, rather than using DHCPv6 or SLAAC. By using tokenized identifiers, hosts can still determine their network prefix by use of SLAAC, but more readily be automatically renumbered should their network prefix change [1]. Tokenized IPv6 Identifiers are described in the draft [1]: <draft-chown-6man-tokenised-ipv6-identifiers-02>. ip token set - set an interface token set the interface token to the kernel. TOKEN the interface identifier token address. dev DEV the networking interface. ip token del - delete an interface token delete the interface token from the kernel. dev DEV the networking interface. ip token get - get the interface token from the kernel show a tokenized interface identifier of a particular networking device. Arguments: coincide with the arguments of ip token set but the TOKEN must be left out. ip token list - list all interface tokens list all tokenized interface identifiers for the networking interfaces from the kernel.
