Hi, Here are two fixes for ipconfig/dhcp, the second of them being required for my dhcp3 server to accept ipconfig's requests. Thanks, Louis Louis Rilling (2): ipconfig: Fix missing dhcp_end field ipconfig: Fix null ciaddr on DHCPREQUEST during SELECTING state usr/kinit/ipconfig/dhcp_proto.c | 4 ++-- usr/kini...

Hi, I had the problem that 'ipconfig' as DHCP client in Debian-squeeze could not get DHCP Offer reply from the built-in DHCP server of the cheap route that I have. The name of the router is 'MegaBitGear TE4571E' which I got at contract of ADSL Internet access service in 2009. The router is not too old and can reply to ot...

From: Geert Stappers <stappers at debian.org> To make klibc-ipconfig transmit the DHCP vendor class "d-i" and get the DHCP preseeding filename in a text file, it needs the attached patch. belows patch allows ipconfig to be used in Debian installer once the hostname is sent too, see http://blog.andrew.net.au/2006/05/17#d-i_dhcp_hacking Signed-off-by: maxi...

Hi, it seems that ipconfig has a problem if multiple devices are up and connected to the same network. It seems that it uses the wrong socket/device index to compare it to incoming packet. To be more precise, the packet gets discarded in do_pkt_recv as the ifindex from state differs always from the incoming packet To reprod...

hello, Preparing my first klibc maintainenace release. :) My plan is to have the patches cook in klibc-queue and once everythings is fine deploy them in the main klibc repo. Please test/review belows patches. I plan to release the current queue really soon for klibc 1.5.20 due to the urgent ipconfig fixes. For now you find my patch queue on: http://git.kernel.org/?p=libs/klibc/klibc-queue.git;a=summary beware that this patch-queue might rebase from time to time in the future. The current diff and shortlog show the ipconfig centric fixes. Erwan Velu (1): [klibc] ipconfig: non zero exit...

The ipconfig code does not drop incoming packets that it can't handle. Since the packet socket sends ipconfig its own broadcast requests, ipconfig has the unfortunate behaviour of eating 100% of the CPU time when it does not receive an immediate response to its outgoing requests. This patch fixes the prob...

...a timeout occured and the correct address was acknowledged only by a retransmittion after a few seconds, or 2. Be called when no packets where in the queue, so packet_discard() just delayed until some new packet arrived, and this new packet was again discarded. I've seen many times ipconfig needing many seconds to configure a card (in my school we have 2 dhcp servers, maybe this makes the problem more common). I think I corrected the function return values, and in my tests (with either one or two dhcp servers) now ipconfig gets an address in only a few msec. Sorry, but this means tha...

klibcs ipconfig tries to guess the nameserver if no nameserver is provided. This may happen due to misconfigured dhcp or the use of the ip= parameter. This patch removes the guessing from ipconfig as it is not possible for any other script to determine if the provided nameserver is valid or a guessed one. If the...

When configuring multiple interfaces, the existing logic in ipconfig can fail if DHCP replies are received out of the expected order, or if one or more interfaces never receive replies. The current ipconfig logic uses a single packet socket to handle all incoming DHCP replies. If, for example, the host has two interfaces, A and B, and only B will be sent a DHCP r...

Hello, I found a bug in ipconfig and I'm sending a proposed patch for it. I've only seen it happen in 2 dhcp-server environments. Scenario: ipconfig sends a DHCP_DISCOVER, server A answers with a DHCP_OFFER, server B answers with a DHCP_OFFER, ipconfig sends a DHCP_REQUEST for server A, ipconfig accepts the DHCP_OFFER from...

Hi, ipconfig is used in ltsp (thin clients) initramfs. Some of the users have to have 2 dhcp servers in ltsp environments, so they hit on this problem: The first dhcp request is from the pxe rom boot code. This code ignores any dhcp offers that don't have a filename field. So they always get the correct add...

Hi!! I found your ipconfig stuff in the udev rpm in SuSE 9.1. I'm about to setup a initramfs (pretty cool - much better than initrd) to boot linux diskless clients over the net. All the tools I would need, seem to be there with ipconfig/nfsmount ... I like to use the information I get from PXE/syslinux or Etherboot...

I had an odd situation yesterday, klibc 1.5.17 ipconfig was trying DHCP on all 3 NICs in the server, but one has a bad switch that causes the link on eth2 to go up/down every 10 seconds. IPconfig would just time out. If I tell ipconfig to only try eth0, then DHCP address is configured, and the netboot proceeds 100%. I'll take a peek at the code b...
