I don't know as to how ifconfig sets it up, but its a piece of cake to edit /etc/network/interfaces to do that. If I bring in a new router, I uncomment this stanza in the interfaces file: ================ #auto eth0:1 # to access reset to 192.168.0.1 routers/switches on the 2nd cat5 port #iface eth0:1 inet static #address 192.168.0.3 #netmask 255.255.255.0 ============== giving me an address I can use to talk to and configure the new router. And I can recall doing it all with a nearly 20yo version of ifconfig the first time I needed to, following the instructions given to me over the phone from our network guy at the tv station. But remembering the arcania of how I did it then, vs the quick edit shown above, followed by a sudo service networking restart, is for me, buckets easier. > (2) is really bad, especially the part where it does not show > all of the IPs that were assigned by other tools, for example Huh? ifconfig doesn't even need a -a option to show me eth0:1 if ts configured and up. It does need the -a if the interface is configured but down. > NetworkManager, or Debian's own ifupdown via > /etc/network/interfaces. Please don't equate those two. Despite having a dhcpd server configured in my router, and which my lappy and my kids telephones can use without any problems, it (N-M) has yet, at this location, to achieve a working connection for any of my machines. My lappy uses wicd IIRC. N-M will tear a working connection down and leave you sitting under a bush on a deserted, .2 acre island. So I long ago learned the usefullness of the sudo chattr +i filename command as it got done to the various network related files, in a race to beat N-M's blanking of /etc/resolv.conf. Fortunately N-M had the great good sense to not load up the logs complaining about the loss of its access to those files. Lately, its been made removable, which for me is a "Good Thing". I agree with the concept of making networking just work, but the concept and the reality are not even in the same building here. That could even be my fault because I've never used the first 2 class D 192.168.x.x addresses for my home network. One more roadblock for the black hats to climb over, and in 20 years I've not been touched. > Regards, > Christian Cheers Christian, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
