Run `ip a s`; ifconfig sucks and won't show any such address set up by ip.

Can we still hope that display of alias through ifconfig will be fixed?
(In reply to comment #5) > Can we still hope that display of alias through ifconfig will be fixed? No; ifconfig and these 'aliases' have been deprecated since 2.2 kernels; please totally forget about this concept which doesn't make any sense whatsover and use iproute2.
Doug: it works because baselayout on your system used ifconfig to set up things the default is to use iproute2 which does not create aliases in the way ifconfig does
except net-tools is in the system profile and iproute2 is not so most people's systems are setup with ifconfig and not iproute2.
which is irrelevant. Paolo is complaining that ifconfig does not list all ip addresses as iproute2 adds them and the answer is "ifconfig sucks and is unmaintained, you should use ip".
Just a simple question. Why does ifconfig, which is de facto an tool for configuring and examination of network interfaces (for aliases too), work correctly in all distribs and only in special cases (unexplainable) it doesn't work? > ifconfig and these 'aliases' have been deprecated since 2.2 kernels; Where is this sentence from? $ uname -r 2.4.35 $ ifconfig eth0 Link encap:Ethernet HWaddr 00:30:48:51:D7:D2 inet addr:xxx.xxx.xxx.xxx Bcast:xxx.xxx.xxx.xxx Mask:255.255.255.224 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Base address:0xd000 Memory:feba0000-febc0000 eth0:1 Link encap:Ethernet HWaddr 00:30:48:51:D7:D2 inet addr:xxx.xxx.xxx.xxx Bcast:xxx.xxx.xxx.xxx Mask:255.255.255.224 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Base address:0xd000 Memory:feba0000-febc0000 Why does it work? Why does ifconfig work as usual in just installed Gentoo 2007.0 ? If mentioning "been deprecated since 2.2 kernels" then why are ifconfig and aliases supported everywhere?
your statement is incorrect. the behavior you see in Gentoo can be seen in other distros. any system that adds additional ip addresses via iproute will not be visible to ifconfig. if you dislike the behavior, disable the iproute module in baselayout and instead force ifconfig.
