A stupid question: which is recomended? I have 1 interface eth0. I need to set about 20 virtual interfaces eth0:xx on it. If I create them with ifconfig eth0:xx I see it with ifconfig and with ip addr ls. If I set it with ''ip addr add'', ifconfig don''t show them, but ''ip addr ls'' and ''route'' show them. So, which is better? Thanks in advance. PS: I can''t find anywhere docs ab...

I don't have ifconfig on my new installation of CentOS 5.6, but it is on my server in the cloud. What package contains it? Thanks, John -- John J.

Hi! I installed CentOS 7 today, it's a minimal install, so it didn't have ifconfig command. So I installed net-tools, however I can't add ipv6 address to it. # ifconfig enp0s3 add fc00::1002/124 SIOCSIFADDR: Permission denied. Yes, I'm running as root. CentOS is running in a Qemu instance with e1000 ethernet card.

Hello, I how an embedded processor that needs to act as a bridge between a wireless and wired network. I have managed to bring up the bridge fine. I can also bring up the bridge with a static ip address. However I can not figure out how to bring up the bridge with a dynamic ip address. Is it possible to for a bridge to get a dynamically assigned ip address? Oliver

...on both hosts, but pinging hosta from hostb wouldn't work until hosta pinged hostb. I've used an earlier version of tinc before in a different environment with no problems, and vaguely remembered a more complicated tinc-up script, so I dug about in the archives. My tinc-up now looks like: ifconfig "$INTERFACE" hw ether fe:fd:0:0:0:0 -arp ifconfig "$INTERFACE" 10.0.0.1 netmask 255.0.0.0 The first ifconfig line isn't mentioned in the current documentation, perhaps it should be updated?

So why is "ifconfig eth0 up" not connecting? Thanks for your help. Mike.

Moi! I upgraded Xen-2.0.1 to Xen-2.0.5 (testing) and everything compiled cleanly. I''m still able to boot dom0 and start domUs but networking doesn''t work anymore. xen-br0 appears in dom0, but vif-interfaces now only when ifconfig -a is used. Interface appears in domU and all seems to be fine, except no any data doesn''t move in any direction. I can''t even ping between dom0 and domU. So it creates an interface, but somehow it doesn''t work properly. What might be wrong? No firewalls enabled atm. Here...
