PXELinux from a DHCP server - read the docs - couldnt be simpler. I'm afraid its beaten me, no matter what I do I always get the same result at the client side "PXE-E53: No boot file found" For the life of me I cannot see what I'm doing wrong and would appreciate any assistance in trying to diag.

Hi, I was wondering if anyone had a good dhcpd.conf and /tftpboot files for a EPIA-M motherboard with RedHat 9.0.... Or maybe just a configuration that works with the EPIA-M (doesn't matter which type of linux). I'm trying to boot the system from the network and it seems to be getting to downloading pxelinux.0 but then nothing happens after that.... I'm using ISC dhcpd V3.0pl2,

I''m trying to get DHCP working with DomU clients. I don''t want to use libvirtd. There''s a dhcpd on the machine and it works fine for all clients in the network, but not for DomUs. If I set a static IP on the DomU all networking for them is fine, so there''s no general networking problem. I use the xen 3.2 packages for CentOS on CentOS 5.1. There was a public

Here is the scenario: I have one server with kernel 2.4.24 with a bridge br0 made of 2 interfaces, eth0 and tap0 (the last is an OpenVPN tunnel), and one remote computer connetting through tap0. If I assign a static IP to the remote computer, the bridge works perfecly (so I think the problem is not OpenVPN-related). If I start a DHCPd on the server and I configure the remote client to get the

Hello, I've got an analog phone which is currently receiving unsollicited FAX calls from PSTN. For learning purpose, I'm preparing an Asterisk/SPA3102 setup that would let voice calls come in and out and translate incoming FAX calls to TIF files (forwarded through email)). My target setup is : PSTN <-- analog--> SPA3102 Line Port <-- SIP --> Asterisk <-- SIP -->

I have a CentOS 6.4 VM that is getting its DHCP information from dnsmasq (a libvirt instance). However, it is not applying the routing information. Attached is a tcpdump of the dhcpc output.

hi everybody I'm looking at my setup and got stuck I have a box with two NICs on the same subnet, and another box similar, also two NICs on one subnet, all four NICs are on the same subnet. Now, that second box has also a virtual NIC (libvirtd's bridge route mode) and VMs guests are using it, traffic to that virtual net is routed via 1st real NIC. This second box dhcrelays to the
