Hi,
Try using something like this if you want to use only server 1.1.1.1:
forward only;
forwarders { 1.1.1.1; };
Kind regards,
Cristian Ciupitu
Correct Cristian. Using forward only problem is solved.
Many thanks.

usb patch
I have an RCA VR5320 digital voice recorder. It has a usb connector, but isn't recognized by SL 5.6. I get log messages of the form kernel: usb 1-5: new high speed USB device using ehci_hcd and address 4 kernel: usb 1-5: ep0 maxpacket = 32 This is evidently a known problem and there is a patch for drivers/usb/core/hub.c with the comment A few devices (such as the RCA VR5220 voice recorder) are so non-compliant with the USB spec that they have invalid maxpacket sizes for endpoint 0. Nevertheless, as long as we can safely use them, we may as well do so. I think this patch is incorporated in 2.6.32 kernels. Q1: Am I correct in thinking that I would have to compile a whole new kernel, as opposed to just a module, to incorporate a patch to hub.c? Q2: Is there any sort of module or userspace hack I could try instead? I don't want to get into a position of maintaining my own kernel. I'd rather wait until I catch up with 2.6.32 and impose on friends with newer kernels or windows machines in the meantime. Thanks. Stephen Isard

A1: Yes, it is a single module, but you'd need to pull the source from the new kernel, since it is a kernel module. You may be able compile it with the source of the current kernel, but since you're pulling from a new kernel, it might have dependencies in the newer kernel. In other words, you're welcome to try. A2: No userspace hack that I know of, as USB operations are a kernel- level thing. j -- Joshua J.

The SL 5.x kernels will remain to be based on 2.6.18 until EOL. ;) That is how TUV maintain a stable kernel ABI for the life of EL5. If you would like to have a SL kernel based on 2.6.32, please install SL 6.x :) Regards, Alan.

I was rather surprised that Alan did not mention ELRepo's kernel-ml. :-O kernel-ml-2.6.35 does have the patch referenced here: https://lkml.org/lkml/2010/11/19/609 I should also note that kernel-ml is not for production use but it's been quite stable and Alan has been doing a good job of keeping it up to date. :-) http://elrepo.org/tiki/kernel-ml Akemi

That looks like a good solution apart from the known bug in iptables, which is a bit scary. I'll have to check into whether I use any of the commands that trigger the bug and cause iptables to stop working. Regards, Stephen Isard
