I have debian hosts which are connected through trunk port on 5 different vlans. But this host respond to arp "who-has" requests of all of their differents ip.
Hi All,
I have 2 NICs in my U9.04 Server box (eth0, eth1). After I added 2 virtual interfaces for each physical interface (eth0:1,eth0:2,eth1:1,eth1:2), the MAC addresses of all the interfaces have changed to that of eth0. Because eth1 was configured to be on my local network, I can't access the box remotely anymore.
I have following setup:
Server 1
auto eth0 iface eth0 inet static address 192.168.1.101 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255
auto eth0 iface eth1 inet static address 192.168.3.102 netmask 255.255.255.0 network 192.168.3.0 broadcast 192.168.3.255
Server 2
auto eth0 iface eth0 inet static address 192.168.1.102 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.
I've setup Ubuntu server along with ufw as a firewall.
To start, I have two networks:
Public: 66.xxx.xxx.70 - 66.xxx.xxx.78
Private: 192.168.3.1 - 192.168.3.255
My network config:
auto eth0
iface eth0 inet static
address 66.xxx.xxx.70
netmask 255.255.255.0
network 66.xxx.xxx.0
broadcast 66.xxx.xxx.255
gateway 66.xxx.xxx.1
auto eth0:0
iface eth0:0 inet
I can't ifdown an interface on a Debian 6.0.5 box;
user@box:/etc/network$ sudo ifdown eth0 && sudo ifup eth0
ifdown: interface eth0 not configured
SIOCADDRT: File exists
Failed to bring up eth0.
user@box:/etc/network$ cat interfaces
auto lo
iface lo inet loopback
allow-hotplug eth0
allow-hotplug eth1
auto eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.255.255.0
gateway 10.
The IP does no longer respond to a remote ping
With restart I mean:
lxc-stop -n vm3
lxc-start -n vm3 -f /etc/lxc/vm3.conf -d
--
/etc/network/interfaces
auto lo
iface lo inet loopback
up route add -net 127.0.0.0 netmask 255.0.0.0 dev lo
down route add -net 127.0.0.0 netmask 255.0.0.0 dev lo
# device: eth0
auto eth0
iface eth0 inet manual
auto br0
iface br0 inet static
address 192.22

I've got ProxmoxVE2.1 ruled KVM node on Debian and bunch of VM's guests machine.
That is how my networking looks like:
# network interface settings
auto lo
iface lo inet loopback
# device: eth0
auto eth0
iface eth0 inet static
address 175.219.59.209
gateway 175.219.59.193
netmask 255.255.255.224
post-up echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp
And I've got two
I have to NICS, eth0 is static, eth1 uses DHCP.
I have these configured through /etc/network/interfaces:
Code:
auto lo eth0 eth1
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0
iface eth0 inet static
address 192.168.58.1
netmask 255.255.255.0
broadcast 192.168.58.255
