For the better part of a YEAR now, I've put up with the following error message, unable to trace its origin: # /etc/init.d/net.home restart * Caching service dependencies ...

[ ok ] * Waiting for IPv6 addresses (5 seconds) .. [ ok ] Some sleuthing revealed that the netifrc script, when it asks for the MAC address of my bridge (home), it instead of returning just ONE MAC address, it returns the MAC address of EVERY interface on my system: # /etc/init.d/net.home -d restart + for module in ${MODULES} ++ command -v macnet_pre_start + '[' macnet_pre_start = macnet_pre_start ']' + macnet_pre_start ++ _get_mac_address + local 'mac=00:00:00:00:00:00 30:9C:23:00:64:31 F8:1A:67:00:48:35 F8:1A:67:00:48:35 F8:1A:67:00:48:35 1A:97:02:C7:E0:8C F8:1A:67:00:48:35 F8:1A:67:00:48:35 30:9C:23:00:64:31 F8:1A:67:00:48:35 02:42:86:DF:C3:65 02:42:DB:17:B5:38 02:42:38:D2:F4:5C 52:54:00:0B:EE:D2 52:54:00:0B:EE:D2 FE:54:00:CB:8B:88 1A:97:02:C7:E0:8C' The offending code is /lib64/netifrc/net/iproute2.sh line 526, it runs: LC_ALL=C ip link show "${IFACE}" | sed -n \ -e 'y/abcdef/ABCDEF/' \ -e '/link\// s/^.*\<\(..:..:..:..:..:..\)\>.*/\1/p' which returns the above list of MAC addresses -- the MAC address of *EVERY* Ethernet interface on my computer (including virtual ones). That command should be: LC_ALL=C ip link show dev "${IFACE}" | sed -n \ -e 'y/abcdef/ABCDEF/' \ -e '/link\// s/^.*\<\(..:..:..:..:..:..\)\>.*/\1/p' The word "dev" tells `iproute2` *WHICH* interface is of interest.
I'm not able to reproduce this problem, what iproute2 version are you using? I get the same output with or without the "dev" word. Your report sounds like what would happen if ${IFACE} is somehow unset.
Both iproute2 and busybox that are stable as of this writing (4.17.0-r1 and 1.29.3, respectively) support "ip link show <interface>" to only show that interface, and will throw errors if the interface provided does not exactly match an interface on the system. Please provide the output of the following commands: ip -V LC_ALL=C ip link show home # obviously after the interface has been created sed --version LC_ALL=C ip link show home | sed -n -e 'y/abcdef/ABCDEF/' -e '/link\// s/^.*\<\(..:..:..:..:..:..\)\>.*/\1/p'
Also your /etc/conf.d/net would be helpful (attach it).
I'll have to dig up a back-up, as I now have Ubuntu 18.04 running on the affected machine.

Can you share "emerge -pvO iproute2" output?
