$ ip 1: lo: <loopback,up,lower_up> mtu 65536 qdisc noqueue state unknown      link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00     inet 127.0.0.1/8 scope host lo     inet6 ::1/128 scope host         valid_lft forever preferred_lft forever 2: eth0: <broadcast,multicast,up,lower_up> mtu 1500 qdisc mq state qlen 1000     link/ether 00:0e:7f:a9:10:54 brd ff:ff:ff:ff:ff:ff     inet 192.168.0.5/24 brd 192.168.0.255 scope global eth0     inet6 fe80::20e:7fff:fea9:1054/64 scope link         valid_lft forever preferred_lft forever 3: virbr0: <no-carrier,broadcast,multicast,up> mtu 1500 qdisc noqueue state down      link/ether 86:0b:cb:43:63:a5 brd ff:ff:ff:ff:ff:ff     inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 mcserver@helloworld:~$   $ vi /etc/resolv.conf: # dynamic resolv.conf(5) file glibc resolver(3) generated resolvconf(8) #     not edit file hand -- changes overwritten nameserver 192.168.0.5 nameserver 8.8.8.8  $ vi /etc/network/interfaces # loopback network interface auto lo iface lo inet loopback  # primary network interface auto eth0 iface eth0 inet static         address 192.168.0.5         netmask 255.255.255.0         network 192.168.1.0         broadcast 192.168.0.255         post-up iptables-restore < /etc/iptables.up.rules         dns-nameservers 192.168.0.5 8.8.8.

the following line wrong:

iface eth0 inet static     address 192.168.0.5     netmask 255.255.255.0     network 192.168.1.0 <<<<<<<<<<<<<<<<<<<<<<<< should 192.168.0.0     broadcast 192.168.0.255     post-up iptables-restore < /etc/iptables.up.rules     dns-nameservers 192.168.0.5 8.8.8.8

also, there doesn't seem default gateway setup.

not having more info network, suggest adding following line @ end:

    gateway <your.router.ip.address>

so, assuming router ip address 192.168.0.1, whole entry:

iface eth0 inet static     address 192.168.0.5     netmask 255.255.255.0     network 192.168.0.0     broadcast 192.168.0.255     post-up iptables-restore < /etc/iptables.up.rules     gateway 192.168.0.1     dns-nameservers 192.168.0.5 8.8.8.8
