internal networking without bridging

[dcdieci]

Hi,

i know this topic has been discussed for several times but i dont get my internal network working correctly.
i have a lenovo netbook r61 as a host system with vista (192.168.2.50) behind a router (192.168.0.1). i do want to run ubuntu 9.04 in virtualbox and connect internally with a static ip e.g. 192.168.2.51. (from vista host to ubuntu client).
i dont want to use bridging. i tried bridging but it resulted in a system freeze for several times.(this could be an issue due to the network adapter (Intel(R) Wireless WiFi Link 4965AGN).
is there an option to handle this?

If you want it on the same net as your host then it must be bridged.

[dcdieci]

ah ok.
actually it must not be in the same net. i just need a static address, so i can access apache and the system via ssh from my vista host.

Then I would suggest using two network interfaces. One NAT to reach internet. One host only which will give full access between host and guest. This could be set to a static address in the guest. Host already has a defined one 192.168.56.1 unless one changes things.

hi,
thats what i already tried. i choose 2 adapter one nat (for internet) and one for the internal communication between host and client with static ip, i choose "host only" adapter. ->boot ->inet ist working

output /etc/network/interfacesl

Code: Select all

auto lo
iface lo inet loopback
auto eth0

ifconfig

Code: Select all

so now i tried to edit coonections in network connection manager. there i see eth1 and eth2.
i addes address 192.168.2.54 netmask 255.255.255.0 gateway 192.168.2.1 for eth2

but im still not able to ping from my vista client. the other direction is working pinging from ubuntu to vista .
any ideas?

[baf]

remove
/etc/udev/rules.d/70-persistent-net.rules
in your guest and add
auto eth1
to your interfaces then reboot it.
After that come back with your ifconfig if it doesnt work.

hi,

i made the changes as recommended but inet is not working any longer. and i cannot ping to the router
ifconfig

eth0
inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0
...


eth1
inet addr:192.168.2.55 Bcast:192.168.2.255 Mask:255.255.255.0

[baf]

Remove the static addresses you set up and let it be on dhcp to start with.

hi,
ty for helping.
inet ist working and i can ping the host from the ubuntu shell but how can i access the opposit way regarding the client does not have a static ip ?
ifconfig shows me 192.168.56.101 for eth2 and i can ping from host.
but i cannot lookup the ip every time i boot, how can i make it static?

kind regards

Now with everything working set the internal interface to static with ip 192.168.56.101 and mask 255.255.255.0 but NO GATEWAY.

[dcdieci]

i changed the following

iface eth1 inet static
address 192.168.56.101
netmask 255.255.255.0

but ifconfig does not show eth1 any longer, only eth0
furthermore inet connection ist getting slow

[baf]

Here is my /etc/network interfaces, how does your look now. also again ifconfig -a

Code: Select all

auto lo eth0 eth1
iface lo inet loopback

iface eth0 inet static
  address 10.0.2.15
  netmask 255.255.255.0
  gateway 10.0.2.2

iface eth1 inet static
  address 192.168.56.100
  netmask 255.255.255.0

hi,
i copied your interfaces conf and rebooted the system.

and now the network ist not getting up (i cannot post ifconfig output, because inet is not available)
iconfig -a

does not show for eth0 and eth1 addrress netmask and broadcast

ubuntus network manager does not show any entry

update
right now i changed interfaces to
auto eth0

and ifconfig shows me that eth0 gets the usual ip address via dhcp
10.2....
but eth1 witht the static settings is not shown
and i do get a very slow internet connection
