Hi all,
I have installed an apache server on my Virtual Machine but I can''t
access to that URL from outside.
However I can ping the virtual machine from outside successfully.
Do you have any ideas about this issue?
thanks in advance,
freddie

Hi Freddie, maybe it''s a checksum problem. try to disable transfer checksumming with ethtool. First you need to check which ID your domU has: # xm list Then you turn off tx checksumming with ethtool: # ethtool -K vif<domU-ID>.0 tx off So for a domU with ID 12 it would be: # ethtool -K vif12.0 tx off Hope it helps, Greetz Age_M freddie weng schrieb:> Hi all, > > I have installed an apache server on my Virtual Machine but I can''t access to that URL from outside. > However I can ping the virtual machine from outside successfully. > Do you have any ideas about this issue? > > thanks in advance, > freddie > > ------------------------------------------------------------------------ > Ask a question on any topic and get answers from real people. *Go to > Yahoo!

Hi Freddie,
there is another workaround so you don''t have to do that stuff
manually.
go to your /etc/xen/scripts directory and edit the xen-network-common.sh
scroll down until you see the following function:
add_to_bridge ()
modify the function from this:
add_to_bridge () {
local bridge=$1
local dev=$2
# Don''t add $dev to $bridge if it''s already on a bridge.
if [ -e "/sys/class/net/${bridge}/brif/${dev}" ]; then
ip link set ${dev} up || true
return
fi
brctl addif ${bridge} ${dev}
ip link set ${dev} up
}
to this (only the last line with ''ethtool'' in it:
add_to_bridge () {
local bridge=$1
local dev=$2
# Don''t add $dev to $bridge if it''s already on a bridge.
if [ -e "/sys/class/net/${bridge}/brif/${dev}" ]; then
ip link set ${dev} up || true
return
fi
brctl addif ${bridge} ${dev}
ip link set ${dev} up
ethtool -K ${dev} tx off
}
So now, everytime a virtual network device is added to the bridge, the
script will turn off checksumming on this device.
Have a nice day

Hi Age_M, Thanks again for your suggestion. This solution worked at first, but it doesn''t work for my second VM. And it doesn''t work for my VM on another machine. It''s really weird!! BTW, I also can''t access to the VNC server on the VMs though I can ping and ssh them. Do you have any idea of this problem? thanks very much, Freddie --- On Wed, 6/11/08, Age_M <Age_M@gmx.de> wrote: From: Age_M <Age_M@gmx.de> Subject: Re: [Xen-users] Cannot access to Apache on Xen VM To: "freddie weng" <freddieweng@yahoo.ca> Cc: xen-users@lists.xensource.com Received: Wednesday, June 11, 2008, 2:51 PM Hi Freddie, maybe it''s a checksum problem. try to disable transfer checksumming with ethtool.
