How do I get this command?It''s a standard Linux command. You didn''t mention what distribution you''re using. In Debian the ip command is in the iproute package, so "apt-get install iproute" should do it. -- CJ van den Berg mailto:cj@vdbonline.com xmpp:cj@vdbonline.com sip:8918316@sipgate.de _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] ''Link veth0 is missing'' - caused by having no ''ip'' command
Hi Richard, don''t know which distro you are using, but the ip command is in a package normally called as iputils. I''m surprised that you don''t have it installed in your distro, because it''s the "modern" way of configuring networking under Linux HTH, Alex Richard Jones schrieb:> I get the error attached below when I run network-bridge start by > hand.

[Xen-users] ''Link veth0 is missing'' - caused by having no ''ip'' command
I get the error attached below when I run network-bridge start by
hand. I have a veth0 interface. Looking at the script, it seems the
reason the command fails is because the script tries to run this
function to test for veth0:
link_exists()
{
if ip link show "$1" >/dev/null 2>/dev/null
then
return 0
else
return 1
fi
}
But there is no "ip" command under Linux, and it doesn''t look
like Xen
installs one either. How do I get this command?
Rich.
----------------------------------------------------------------------
# /etc/xen/scripts/network-bridge start
Link veth0 is missing.
This may be because you have reached the limit of the number of interfaces
that the loopback driver supports. If the loopback driver is a module, you
may raise this limit by passing it as a parameter (nloopbacks=<N>); if the
driver is compiled statically into the kernel, then you may set the parameter
using loopback.nloopbacks=<N> on the domain 0 kernel command line.

I guess that should be added to the list of xen dependencies. -- Alvin Starr || voice: (416)585-9971 Interlink Connectivity || fax: (416)585-9974 alvin@iplink.net || _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
