[PATCH 0/1] ipconfig DHCP bug
Hi guys ipconfig performs not well conformed DHCP client transactions. This bug does not affect 100% of the DHCP servers as some of them are more forgiving than others when considering client side protocol mistakes; i.e When PXE installing on a VMware Workstation using the VMware DHCP server plus a proxyDHCP the bug is not present. When PXE installing on a real PC with a Netgear ISP

BOOTP and no default route
Is there any way to prevent the BOOTP client from injecting a default route? When I originally set things up our DHCP server would not send a default route because there was no gateway, local only. If you leave out the default route, the server will try proxy-arp when ends up putting a default route to itself in the routing table. The problem is that on startup the servers actually

ipconfig:About the length of 'options' field of DHCP packet
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 clients like ISC-dhclient, WindowsXP and Vista.

Polycom or Linksys phones bootp tftp config setup
Hi All, Has anyone gotten the polycoms or the linksys phones to accept oprtion 66 on the dhcp request for the address of the tftp config server? We have the dhcp server issuing the proper IP of the tftp server, but the phones just sit there and never try to contact the tftp server for their configs. We can see the proper option going from the dhcp to the phones with ethereal trace. Thanks JR

DHCP and DomUs: not working
...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 IP address on eth0 and a private IP address on eth0:0. I changed that around after I discovered with tcpdump that dhcpd was replying on eth0 like publicip.bootps -> privateip.bootpc. This isn''t a problem for all other packets, but apparently for DHCP. Bridging is setup with the standard Xen 3.2 network-bridge script by xend like this: bridge name bridge id STP enabled interfaces eth0 8000.000c6e101f84 n...
