Looking at https://techhub.hpe.com/eginfolib/networking/docs/switches/K-KA-KB/16-01/5200-0133_ipv6_config_k/content/ch01s10.html Assume the following... machine1 has a script in /etc/local.d/ that executes... ipv6 address fe80::1 link-local machine2 has a script in /etc/local.d/ that executes... ipv6 address fe80::2 link-local machine3 has a script in /etc/local.d/ that executes... ipv6 address fe80::3 link-local etc, etc. Can I enter... # fe80::1 machine1 fe80::2 machine2 fe80::3 machine3 # ...in /etc/hosts and will it properly match them to the correponding machine? Forget about global addresses for the time being. I simply want to be able to scp and ssh between local machines first. -- Walter Dnes <waltd...@waltdnes.org> I don't run "desktop environments"; I run useful applications
