Hi Guys, i have a problem with PXE/UEFI Boot. Legacy PXE Boot is working fine. I use Dnsmasq with integrated tftp. As Mentioned above, legacy pxe boot is working fine, tcpdump shows: --- start tcpdump legacy pxe boot --- 13:44:16.589197 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from f8:ca:b8:06:7d:ed (oui Unknown), length 548 13:44:20.543910 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from f8:ca:b8:06:7d:ed (oui Unknown), length 548 13:44:20.570008 ARP, Request who-has dhcp.localdomain tell 172.22.135.15, length 46 13:44:20.570024 ARP, Repl...

I''m running a nevada b99 guest on a nevada b99 host. The guest is configured as a dhcp client. When I snoop in dom0 while the guest boots, I see two back-to-back DHCPREQUEST packets issued by the guest. The first of the two packets has an empty UDP checksum; otherwise they seem identical. Is this a bug? Fred Oliver ETHER: ----- Ether Header ----- ETHER: ETHER: Packet 246 arr...

Before I post to networking-discuss I wanted to ask if anyone had tried this on this: I''m trying to run a dhcp-server on a dom0 over a vnic so that the domU''s can get IP addresses. I created a vnic r1 over e1000g0 and gave it a static IP 172.0.94.111/24 so I can run the dhcp server over this vnic. root@lm2-dom0:~# dhtadm -P Name Type Value =======================...

This happened a few times now, I (soft) reboot and do the fsck thing and all is fine until it happens again. Any ideas?

Greetings All. We wanted to be able to parse the DHCP values and options and write a lua script based on the information found. We are also using the CPU flags, but thankfully in at least version 4.04 there is already some CPU value parsing even if it isn't documented. Using the information from the CPU table we wanted to be able to choose the k...

I want to run dhcp and shorewall on the same computer.It is my gateway and that computer doing NAT for my network.How can I set up shorewall to let only users that get theire static ip address via dhcp, not to let users that had static address.

I know this is samba list and I am hoping that someone with MS AD experience can answer this definitively. Does AD have some kind of data exchange between dhcp and dns so that systems which receive a dhcp lease from an AD DC more reliably register their hostname with AD DNS? Looking at the RFC I couldn't see any reason why this should be the case. But it seems that host name registration for all DHCP devices is much more consistent when using AD for...

Hello List, Hello Rowland :-) again I'm having problems with the DDNS. I did it as shown in the wiki. I took all teh scripts from the wiki the dhcp-dyndns.sh is Version: 0.8.9 I configured everything including the failover. When I start the two DHCP-Server everything is perfect. I see the right messages in the log, the two DHCP-Servers are talking to each other. When a Client ask for an IP-adresse he get's one. BUT the DNS-Update is not wo...

...ora as a dom0 with domUs of fedora 4, suse 10.0 and my own home grown file system. It all seems to work fine so far and I am about to start some stability testing I need to do. I am using the current unstable tree based on 2.6.12. One thing I have not figured out is a problem I am having with dhcp. When I set dhcp = "dhcp" in my /etc/xen config files I always get Sending DHCP request ...... timed out! IP-Config: Reopening network devices... Sending DHCP request .. and so forth. I would appreciate any help I can get. Thanks, Johnnie ______________________________________...

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 other DHCP cli...

Hi, ?We have tens of networks(VLANs) in data center with a central Linux DHCP server. each network has their router to do the DHCP relay. So, the DHCP server's configuration files has tens 'subnet' statements. Because PXE booting is standard in whole data center, there are also thousands of static MAC-IP mapping 'host' statements in dhcp configuration. Th...

...least 5) in my environment? I guess the gpxelinux.0 use its own PXE BC and call vendor-UNDI from physical PXE ROM, as a result, gpxelinux.0 could support all my NIC(actually, it is supposed to support all NIC which have PXE ROM) Am I right? 2, From rfc5071, pxelinux should request non-standard DHCP option from DHCP server, option 208-211. In my environment, I am using a Microsoft DHCP (Windows 2008). And I tried to set option 67 (boot file name) to publish pxelinux.0 & gpxelinux.0. I used wildpacket(just like Wireshark) to capture the packets btw PXE client and DHCP server. I could not se...

Hello! Thanks for your answer. Well, I think it has to ask for an IP as I have the same configuration in a different machine (with the same OS) and it works, there I see the DHCP packets and so on, but not here. And yeah, that pepito.conf file exists, this is its content: ##WARNING: THIS IS AN AUTO-GENERATED FILE. CHANGES TO IT ARE LIKELY TO BE ##OVERWRITTEN AND LOST. Changes to this configuration should be made using: ## virsh net-edit pepito ## or other application u...

Hai, ? A bit off topic in the samba forum, but i thinks this is the best place to ask. ? Im having?some troubles to get the dhcp server fully working with samba4. I dont think this is a samba problem, but as i did say here maybe the best placy to ask.. ? It works, but not totaly. The strange thing is for example. ? My debian client is now working.? It adds and deletes as it should.? No problems at all. the only thing is...

I am new to working with samba. We have used samba for years connecting our windows systems to Unix systems services on OS390. Starting in and around November 2002 we can no longer connect. I have gone through the troubleshooting techniques. Our Samba system is up running, the mount points are correct and the config file tested out correctly. If any one is doing this could you please forward

...I realize this is not strictly a PXELINUX question. So I hope you'll indulge me; hopefully some of these PXELINUX experts have seen this before. And can tell me what I'm doing wrong. Or confirm my suspicions. I have a test lab server at work. Split config. The network team manages the DHCP servers, points to our TFTP server. Test subnet has 3 DHCP pools. BIOS PXE, UEFI PXE and catch-all (straight DHCP). DHCP server is filtering on client's initial VCI (option 60).
