Problem with reboot of domU''s
I have been playing with Xen 3.0.1 for some days now, using debian sarge for dom0 and domU''s, and it works like a charm. But, I have a problem with rebooting domU''s. Here is the output from /var/log/xend.log [2006-03-30 13:44:58 xend.XendDomainInfo] INFO (XendDomainInfo:823) Domain has shutdown: name=vmintraweb1 id=5 reason=reboot .

routing problem with domU bridged to two networks
As I received no response on the general CentOS list, I'll repost it here as the question is about Xen virtual machine routing. This is my network setup: http://pastebin.com/kyWpTQYU Lets assume my dom0's eth2 public ip is 1.2.3.33 and my dmz network 11.22.33.96/255.255.255.224 . I have created NAT from my LAN with iptables. You can see my /etc/sysconfig/iptables here:

routing in xen 3.0 domU: icmp gets routed, but tcp/ip only partially
Hello folks, I have a really strange routing problem that no amount of googling and experimenting has been able to solve. Then again, I''m new to Xen and "advanced" networking, so I could be missing something very basic. Summary: an unprivileged domU with PCI frontend for a NIC is used as a router; icmp gets routed, but tcp/ip only partially. I''m using a xen-unstable

Network Interface Problems for DomU Firewall
I am attempting to setup a firewall in a DomU. The firewall program I eventually want to run is Shorewall. Both my Dom0 and DomU are Debian Lenny 64 bit systems. The Dom0 has four physical network interfaces installed. Currently, one of the NICs is hidden using the pciback.hide command in the /boot/grub/menu.lst file. Similarly, the hidden NIC is passed to the DomU using the pci =

how to provide different Xen subnets access to a DomU-installed NAS?
I''ve a Xen Dom0 with 3 vif-bridges defined, one each for LAN, WAN & DMZ. A DomU router/firewall routes between the 3. Works great. After getting advice from the list, I''ve settled on an apporach to file-services; I''ve launched a storage appliance (OpenFiler) in a DomU. For initial access, it attaches to the LAN bridge. I next want to provide access to the NAS

[PATCH] Fix checksum errors when firewalling in domU
Another checksum offload problem was reported on xen-users, when using a domU as a firewall: http://lists.xensource.com/archives/html/xen-users/2006-04/msg01150.html It also fails without VLANs. The path from dom0->domU with ip_summed==CHECKSUM_HW/proto_csum_blank==1 is broken. - skb_checksum_setup() assumes that a checksum will definitely be calculated in dev_queue_xmit(), but the

routing and virtual machines: how to access dmz if bridged to two networks
I am not quite sure if this issue relates to iptables, routing or Xen virtual machines. Too many variables for my simple mind, so I'm asking some advice :) This is my network setup: Internet --- eth2 + CentOS dom0 / firewall / router + eth1 (xenbr1) --- LAN with private IPs --- separate file server and workstations + eth0 (xenbr0)

Help configuring firewall
I am trying to configure a firewall, but nailing down the configuration is eluding me. The box is running Debian stable. Basically, I have a rackmount server with six network cards. eth0 is the internal network, eth1 is a kiosk network, eth2 is a DMZ/wireless network. On the outbound side, eth3 is a DSL connection and eth4 is a cablemodem connection. What I am trying to do is route all internal

[PATCH net-next v3 5/5] xen-netback: enable IPv6 TCP GSO to the guest
This patch adds code to handle SKB_GSO_TCPV6 skbs and construct appropriate extra or prefix segments to pass the large packet to the frontend. New xenstore flags, feature-gso-tcpv6 and feature-gso-tcpv6-prefix, are sampled to determine if the frontend is capable of handling such packets.

Client behind firewall
Hey, I have a Compaq T2000 UPS that I use to power my firewall, dmz, and two internal machines and I've just started implementing UPS monitoring to shut the systems down in the event of an outage instead of relying on me, but I've run into a snag. Reading the documentation, it seems the client has to contact the server. The problem is I really don't want to open a port form the

Firewall transparancy?
Hi! I was thinking, is there a way to use a linux box with Samba running in the DMZ of a firewall and to validate logons from the internal network? I.e. the users workstations are on the protected net on 192.168.111.xx and the Samba PDC resides in the DMZ, running subnet 192.168.222.xx. If it's possible, what ports need to be open?
