networking in centos (through virtualbox)

sycamorex · 09-15-2008, 04:53 PM

I installed centos on virtualbox. During the install I configured network
adapter 1 (NAT) as dhcp to see if it'll pick up the network. It did. Then I changed the config files to assign a static ip to it. I'm connected to the internet through a router (192.168.1.1)

/etc/sysconfig/network:

Code:

NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
GATEWAY=192.168.1.1

# route

Code:

Destination         Gateway     Genmask              Flags    Metric      Ref   use  Iface
192.168.1.0          *                   255.255.255.0     U           0                0        0     eth0
169.254.0.0          *                   255.255.0.0         U            0               0        0     eth0
default                192.168.1.1 0.0.0.0                 UG           0              0          0    eth0

/etc/sysconfig/networking/devices/ifcfg-eth0

Code:

DEVICE=eth0
BOOTPROTO=none
HWADDR=08:00:27:90:F9:62
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.1.222
GATEWAY=192.168.1.1
TYPE=Ethernet

/etc/sysconfig/network-scripts/ifcfg-eth0

Code:

DEVICE=eth0
BROADCAST=192.168.1.255
BOOTPROTO=none
HWADDR=08:00:27:90:f9:62
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.1.222
GATEWAY=192.168.1.1
NETWORK=192.168.1.0
TYPE=Ethernet

/etc/resolv.conf

Code:

search localdomain
nameserver 192.168.1.1

ping 192.168.1.1 gives 'destination not reachable

yum install somefile gives
[Errno 4] IOError ...Temporary failure in name resolution...

Why is it like that - resolv.conf seems to be ok, isn't it.

I don't know if it matters, but it's on a fedora laptop connected
to the router through wireless connection (ndiswrapper)

any hints

thanks

edit: sorry for the output of 'route' I haven't found a way of copying/pasting from virtualbox (centos) to fedora- I just retyped it.

search localdomain should be the last line of the resolv.conf file really and not the first, however it shouldn't be causing that error =/.

thanks for your reply, however, it hasn't helped.

btw, what's this part of route's output:

Code:

169.254.0.0                    *                        255.255.0.0

Why does the network part take 2 octets? Is it anything to do with the fact that it's through virtualbox? Perhaps the nameserver and/or gateway should not be my router's address, should it?

Doesn't surprise me to be honest.

I don't have much (aka any) experience with virtual box. If it's a VM kinda program then it might be that your on a guest and may have to route via your guest. However I would have thought a bridge method might have been better. If you are using VMs might also be an idea just to check you are actually taking a free ip.

I've read the fine manual and it turns out that virtualbox's NAT only supports static ip's with the help of portforwarding.
So the option that would be better for me is Host Interface Networking. This, in turn, according to virtualbox's manual, works only with wired network hardware.
