Hi,

I am new to openvz. I install it folowing the instruction and end up with a host that seems to work fine and 2 guest that I can access with "vzctl enter" but not with "ssh". All ssh attemp seems to connect to the host.

Is there is something to change in my /etc/networking/interface

# cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
         address AAA.BBB.68.38
         netmask 255.255.255.224
         gateway AAA.BBB.68.33

auto eth0:1
iface eth0:1 inet static
         address AAA.BBB.69.209
         netmask 255.255.255.248

auto eth0:2
iface eth0:2 inet static
         address AAA.BBB.69.210
         netmask 255.255.255.248

auto eth0:3
iface eth0:3 inet static
         address AAA.BBB.69.211
         netmask 255.255.255.248

auto eth0:4
iface eth0:4 inet static
         address AAA.BBB.69.212
         netmask 255.255.255.248

auto eth0:5
iface eth0:5 inet static
         address AAA.BBB.69.213
         netmask 255.255.255.248

auto eth0:6
iface eth0:6 inet static
         address AAA.BBB.69.214
         netmask 255.255.255.248

This is the output of sysctl -p

net.ipv4.conf.default.forwarding = 1
net.ipv4.conf.default.proxy_arp = 0
net.ipv4.ip_forward = 1
net.ipv4.conf.all.rp_filter = 1
kernel.sysrq = 1
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0

And this is the output of vzlist -a

      VEID      NPROC STATUS  IP_ADDR         HOSTNAME
       209          6 running AAA.BBB.69.209  sottise.mydomain.com
       210         12 running AAA.BBB.69.210  centos.st-mydomain.com

If I enter 209 and type route I get :

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.0.2.1       *               255.255.255.255 UH    0      0        0 venet0
default         192.0.2.1       0.0.0.0         UG    0      0        0 venet0

I don't know where that 192.0.2.1 is comming from

On the host, "ip r l" give :

AAA.BBB.68.211 dev venet0  scope link
AAA.BBB.69.210 dev venet0  scope link
AAA.BBB.69.209 dev venet0  scope link
AAA.BBB.69.208/29 dev eth0  proto kernel  scope link  src AAA.BBB.69.209
AAA.BBB.68.32/27 dev eth0  proto kernel  scope link  src AAA.BBB.68.38
default via AAA.BBB.68.33 dev eth0

And this is the route output :

Table de routage IP du noyau

default         ip-AAA.BBB-68-3 0.0.0.0         UG    0      0        0 eth0

Thanks for your help
