[Xen-users] SSH ping etc not working between dom0 and domU''s
Hi!
I have a problem with my new Xen setup. I have installed Debian etch
with netinstall and I''m using 2.6.18-6-xen-amd64 kernel in my dom0 and
3.0.3-0-4 version xen hypervisor. I''m using four network cards on my
system and using three of them as xen bridges and dom0 is using the
fourth one only for it''s own. So basicly both of my virtual servers use
a network card (physical one) of their own. The problem is that I can''t
get ssh or ping to work between my dom0 and domU''s. I can get ssh
connection to and from my other linux server using dom0 or one of my
domU''s and connection to internet works also. Here are my domU config
files:
inno:/home/iler# cat /etc/xen/i28
kernel = "/boot/vmlinuz-2.6.18-6-xen-amd64"
ramdisk = "/boot/initrd.img-2.6.18-6-xen-amd64"
memory = 512
name = "i28"
vif = [ ''ip=192.168.1.6,mac=DE:AD:BE:EF:25:10,bridge=xenbr3'' ]
disk = [''phy:/dev/vgxen/i28root,sda1,w'',
''phy:/dev/vgxen/i28home,sda2,w'',
''phy:/dev/vgxen/i28swap,sda3,w'']
root = "/dev/sda1 ro"
extra = ''4''
inno:/home/iler# cat /etc/xen/happo
kernel = "/boot/vmlinuz-2.6.18-6-xen-amd64"
ramdisk = "/boot/initrd.img-2.6.18-6-xen-amd64"
memory = 512
name = "happo"
vif = [ ''ip=192.168.1.7,mac=DE:AD:BE:EF:22:77,bridge=xenbr2'' ]
disk = [''phy:/dev/vgxen/happoroot,sda1,w'',
''phy:/dev/vgxen/happohome,sda2,w'',
''phy:/dev/vgxen/happoswap,sda3,w'']
root = "/dev/sda1 ro"
extra = ''4''

When I try to ssh from dom0 to domU I get this (verbose on):

ssh: connect to host 192.168.1.6 port 22: No route to host
I have asked couple of my friends for help but they couldn''t help me so
I thought to try this mailing list. So if anyone has ideas please share.

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.

I changed my hardware address in /etc/network/interfaces file and booted my computer. Now I can access my dom0 from my domU with ssh but now I can''t access my dom0 from other computers in my network like I used to before changing that hardware address. But here is the output you asked: bridge name bridge id STP enabled interfaces xenbr0 8000.001cf05b69f8 no eth2 vif1.0 xenbr1 8000.001cf05a5d72 no eth3 vif2.0 Ilari Mäkelä _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

And what is the value now? Just leave it. It is called Hardware Address for a reason; just let it have its original value. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Wanted to see if that weird hardware address (FE:FF:FF:FF:FF:FF) had something to do with my problems. Do you have any more ideas what I should check to get the connection between dom0 and domU''s to work?
