I've got an new Server with 2 IP Adresses.
The Main Adress Is connected and uprunning.
I assigned the IP Adress to the vServer but, i wasn't abble to get an connection to the internet.
I tried it, by assigning the IP by to the hostsystem as eth0:1 or just assigning it into the vServer.
It didn't work at all.

Hello,

you shouldn't create eth0:1 or assign IP address in VE!
Please, read manuals! Smile You should use `vzctl set <veid> --ipadd` command.

Ok, first of all, I'm Using Debian Linux 3.1 on two boxes.
Here is, what I did:

I Edited the
/etc/network/interfaces
like this:
# /etc/network/interfaces - network interfaces configuration

# loopback interface

auto lo
iface lo inet loopback

# ethernet interface

auto eth0
iface eth0 inet static
  address 11.22.33.152
  network 11.22.33.0
  netmask 255.255.255.0
  broadcast 11.22.33.255
  gateway 11.22.33.1

# virtual interfaces
auto eth0:1
iface eth0:1 inet static
address 11.22.33.172
network 11.22.33.0
netmask 255.255.255.0
broadcast 11.22.33.255
gateway 11.22.33.1


the I entered following command twice:
#ifup -a
Then I assigned it to the VE
vzctl set 100 --ipadd 11.22.33.172 --save
vzctl start 100
vzctl enter 100
But all of it didn't work.
Im trying to tell him where to find the router, but if this dosn't work, I don't know what to do else.
Is it possible that IP Tables blocks the VE?

You forgot to add --save option, when setting IP address:

vzctl set 100 --ipadd 11.22.33.172 --save

I tried to add routing information or korrekt the netmask, but every time i restarted the ve, every setting is reseted to this.

I tried this as Routes
up route add -net 11.22.33.1 netmask 255.255.255.0 venet0
up route add default gw 11.22.33.1 venet0

But as i said, vzctl overwrites my settings.

Sad

From in the VE context, you cannot manage ip addressing at all. Any attempts via config files or ifconfig will be futile. Instead, you should use "vzctl set VEID --ipadd x.x.x.x --save" from the HN as already explained and documented in the manual. So, just to be clear, you do not need to / cannot use debians interface management scripts/configs from inside the VE. The VE ifconfig output you provided shows that the address was added correctly to your VE. Assuming your HN can route that address properly, your VE will have network connectivity.

but how do i change the netmask?
My Providers only accepts 255.255.255.0
Also how do I tell hime to use the default gateway of the provider?
I enter a nameserver into the ve (resolv.conf)

I don't get it, why it doesn't work?????? Embarassed

First, have you read the openvz manual?

Everyone on this forum is very friendly and happy to help solve problems to push the project forward. Openvz has excellent documentation and community support- but we cannot learn it for you.

I tried and tried almost everything.
I don't know how to go on any further.
I created it, like it was shown in several Tutorials.
I can't ping inside of the server to the outside.
The only thing that happens is, that ping tries to send an ICMP Request.
But nothing happens.
I tried to check the firewall, but thats not the Problem.
Can't anybody help me?

Hi,

a possible solution can be, to set a private IP to VE, and use DNAT descibed in the wiki (-> http://wiki.openvz.org/Using_NAT_for_VE_with_private_IPs )
with your offical ip (eth0:alias) eth0:1

I assined the IP directly to that VPS.
But the Problem is the Subnet mask, that is propaly not working.
How do I find out, if the IP isn't or is accepted by anykind of Firewall?

thx

Ok,
ping on the host system works over
eth0 and eth0:1

this is, what ifconfig prints:

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1

UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1

Ass you can see, venet0:0 is setup correctly, the only missmatching is the subnetmask with 255.255.255.0

How can I correct this, or wath went wrong?

I will try to setup the vps today brandnew and try to bring her up then

thx

Here is what i did on this run.
First
apt-get install debootstrap
debootstrap --arch i386 sarge /vz/private/777 http://ftp.freenet.de/debian
vzctl set 777 --applyconfig vps.basic --save
echo "OSTEMPLATE=debian-3.1" >> /etc/vz/conf/777.conf
vzctl set 777 --ipadd x.x.x.x --save
vzctl set 777 --nameserver x.x.x.x --save
as Nameserver i used this on:
nameserver 134.109.192.18

cat << EOF > /vz/private/777/etc/apt/sources.list
deb http://ftp.freenet.de/debian stable main contrib non-free
deb http://security.debian.org stable/updates main contrib non-free
EOF

vzctl set 777 --hostname hostname --save

vzctl start 777

vzctl enter 777
export PATH=/sbin:/usr/sbin:/bin:/usr/bin

pwconv

apt-get update

The only thing is, I see is failure resolbing ....
or failed to fetch .......
I did everything as mentioned inside the manuals.
I don't know what to do else.
I am, how should i say, helpless.
I don't know what i am doing wrong.

I'm going to take a guess here, are the two IP addresses from your provider on DIFFERENT subnets? If so, give this a try (works for me). Please report back so that I can update the wiki.


Example with hwnode on 1.2.3.0/24 and VE somwhere on 2.3.4.0/29 with a gateway of 2.3.4.1:


Configure hwnode subnet normally. Then to add the second subnet for the VE:

node# route add -net 2.3.4.0/29 eth0
node# ip rule add from 2.3.4.0/29 table 1
node# ip route add default dev eth0 via 2.3.4.1 table 1

Then do your 'vzctl set veid --ipadd 2.3.4.2 --save' as normal.


That should be it. You can 'man ip' to read more about 'Route tables'. If you add yet another subnet, you might use table 2.


I believe I originally read about this on
https://wiki.openvz.org/Source_based_routing
