I want to test Bruno's ipv6 patch, but where can I get the latest vserver-2. 1.1 patch for kernel-2.6.16.18?
I've get kernel-2.6.16.18 from www.kernel.org, and patch-2.6.16.18-vs2.1.1rc21-ipv6a.diff from http://homepage.internet.lu/brunop/vserver/. But I can't get vs2.1.1 patch for kernel-2.6.16.18. I searched in http://vserver.13thfloor.at/Experimental/, but only get patch-2.6.16.17-vs2. 1.1-rc21.diff.

Sorry if this is OT for this list, but let me see if I understand: are you saying that FreeVPS' virtual network interfaces isolate TCP traffic, but not UDP? And therefore dhcpd won't run in a FreeVPS VPS? Can this really be true? I can't find any other mention of it, and http://www.freevps.com/tracker.html says that FreeVPS has "private udp socket lists". If this is true it's very bad for FreeVPS. Thanks, Andrew. ------------------------------ Message: 2 Date: Fri, 26 May 2006 10:08:26 -0400 From: Avery Pennarun <[EMAIL PROTECTED]> Subject: Re: [Vserver] Re: About the tcp/ip stack ...

Although dhcp packets use UDP, they're very weird UDP packets because the client doesn't necessarily have an IP address at the time it needs to receive them. Thus, dhcpd uses a different socket layer than normal UDP/TCP, which I gather from the above is not divided between contexts in freevps. Almost nothing uses that socket layer except things like tcpdump, dhcpd, some intrusion detection systems, and so on.

To: "Linux-VServer ML" <[email protected]> Cc: Yann Dupont <[EMAIL PROTECTED]> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset="iso-8859-1" Hi All, My IPv6 patch has progressed a lot during the last days. You can fetch the latest version from: http://homepage.internet.lu/brunop/vserver/ Status of the patch at time of this writing: - add/remove IPv6 address to/from context - limit source of outgoing TCP/UDP packets - limit possible addresses for binding sockets - while filtering guest's devices, show those with available IPv6 addresses - display IPv6 addresses in /proc/virtnet/<nid>/... Limitations: - Multicast no tested (behavior is side-effect of UDP) - Possible race condition when removing ipv6 module (with simultaneous listing of devices inside guest) - RAW sockets are not filtered (at most as sideeffect) For userspace not sure if util-vserver can already manipulate IPv6 addresses associated to guest... Possible alternative: vserver-utils (1.0.4 branch, svn HEAD) with libvserver (trunk, svn HEAD) has support for it. (vncontext -A -6 -a ::1 -n 123) Please report you success or failure, and good luck while testing!

Aren't they just broadcast packets, sent to 255.255.255.255 on port 67/udp? Anyway, this is OT here so I'll pursue it on the FreeVPS lists.

Thus i can have one o/s as host like centos or Mandriva and then run Suse, Ubuntu, Fedora, gentoo, etc. as guest virtual servers. How does one install these guests? ARe there images so less disk space is used for installation and shared files(kernal) need not be duplicated? Sorry, this is mentioned in other documentation but i could not find an indepth or step by step method/explanation. Please any help or explanation or reference to a documentation source. Thank you so much.

Thanks, > Andrew. > dhcpd don`t use udp sockets. dhcpd use raw socket and receive packets via bpfX device. It`s one one reason who dhcpd don`t work with later versions FreeVPS, but now i release patch to fix it and use L2 address to inter context routing. -- FreeVPS Developers Team http://www.freevps.com Positive Software http://www.psoft.net ------------------------------ _______________________________________________ Vserver mailing list [email protected] http://list.linux-vserver.org/mailman/listinfo/vserver End of Vserver Digest, Vol 26, Issue 46 *************************************** _______________________________________________ Vserver mailing list [email protected] http://list.linux-vserver.org/mailman/listinfo/vserver
