OK, realised out that it's feature. Entries in /proc/sys/net/*/conf/ are not created if interface doesn't have at least one ipv4/ipv6 address. I can think of workarounds for most of problems (although it breaks a hell lot of software here), but how I suppose to configure ipv6 settings for interfaces which have to obtain global ipv6 address via autoconf so that it will work even if cable is not plugged in? I did via /etc/sysctl.conf, but now ... machine boots with no link => no link-local address => no /proc/sys/net/ipv6/conf/ => configuration fails. regards, -- Hasso Tepper
