Hi,

I think you might want to check this:

Here is ifconfig from dom0:

eth0      Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
        inet addr:192.168.1.5  Bcast:192.168.1.255  Mask:255.255.255.0

Especially the hardware address.

Hi, Thanks for the reply. That is the hardware address that was setup when I installed Debian. If I try to change that hardware address in /etc/network/interface config file I can't ssh to my dom0 machine anymore from other computers in my network. I know it looks weird but if I change it my network on eth0 dies. Now I changed my configuration a bit and it looks like this now: This is my network script at the moment, found this one from this list: #!/bin/sh brctl addbr xenbr0 brctl setfd xenbr0 0 brctl sethello xenbr0 0 brctl stp xenbr0 off ifconfig eth2 0.0.0.0 down ifconfig eth2 0.0.0.0 up brctl addif xenbr0 eth2 ifconfig xenbr0 10.0.0.1 netmask 255.255.255.0 sleep 5 brctl addbr xenbr1 brctl setfd xenbr1 0 brctl sethello xenbr1 0 brctl stp xenbr1 off ifconfig eth3 0.0.0.0 down ifconfig eth3 0.0.0.0 up brctl addif xenbr1 eth3 ifconfig xenbr1 10.0.1.2 netmask 255.255.255.0 sleep 5 ifconfig eth2 0.0.0.0 ifconfig eth3 0.0.0.0 exit 0 ifconfig on dom0: eth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet addr:192.168.1.5 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:296 errors:0 dropped:0 overruns:0 frame:0 TX packets:267 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:29514 (28.8 KiB) TX bytes:33556 (32.7 KiB) Interrupt:16 Base address:0x6000 eth2 Link encap:Ethernet HWaddr 00:1C:F0:5B:69:F8 inet6 addr: fe80::21c:f0ff:fe5b:69f8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:90 errors:0 dropped:0 overruns:0 frame:0 TX packets:14 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7356 (7.1 KiB) TX bytes:1056 (1.0 KiB) Interrupt:22 Base address:0xe000 eth3 Link encap:Ethernet HWaddr 00:1C:F0:5A:5D:72 inet6 addr: fe80::21c:f0ff:fe5a:5d72/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:253 errors:0 dropped:0 overruns:0 frame:0 TX packets:159 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:22429 (21.9 KiB) TX bytes:17327 (16.9 KiB) Interrupt:17 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 RX packets:26 errors:0 dropped:0 overruns:0 frame:0 TX packets:26 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2360 (2.3 KiB) TX bytes:2360 (2.3 KiB) vif1.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:9 errors:0 dropped:0 overruns:0 frame:0 TX packets:74 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:252 (252.0 b) TX bytes:6114 (5.9 KiB) vif2.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:174 errors:0 dropped:0 overruns:0 frame:0 TX packets:242 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:14867 (14.5 KiB) TX bytes:21373 (20.8 KiB) xenbr0 Link encap:Ethernet HWaddr 00:1C:F0:5B:69:F8 inet addr:10.0.0.1 Bcast:10.0.0.255 Mask:255.255.255.0 inet6 addr: fe80::21c:f0ff:fe5b:69f8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:99 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6348 (6.1 KiB) TX bytes:552 (552.0 b) xenbr1 Link encap:Ethernet HWaddr 00:1C:F0:5A:5D:72 inet addr:10.0.1.2 Bcast:10.0.1.255 Mask:255.255.255.0 inet6 addr: fe80::21c:f0ff:fe5a:5d72/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:111 errors:0 dropped:0 overruns:0 frame:0 TX packets:9 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6642 (6.4 KiB) TX bytes:594 (594.0 b) and kernel routing table on dom0: Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 xenbr0 10.0.1.0 0.0.0.0 255.255.255.0 U 0 0 0 xenbr1 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 Now I can ping my dom0 from domU's but everything else is still failing. Can't ping my domU's from dom0 and ssh doesn't work at all. So there is little progress because ping wasn't working at all before and now it works from domU to dom0.
