Bug#432977: ipconfig fails to get ip configuration from dhcp-server

A normal DHCP process looks like this: DHCPDISCOVER (client-server) DHCPOFFER (server-client) DHCPREQUEST (client-server) DHCPACK (server-client) Using the ipconfig tool in the klibc-utils, the procedure looks like this: DHCPDISCOVER (client-server) DHCPOFFER (server-client) DHCPREQUEST (client-server) The DHCPACK is missing, an there is never an IP configuration obtained. It seems, that not transmitting an bootp gateway in the DHCPREQUEST package solves this Problem. (Patch attached) hmm i guess you have the corresponding tcpdump logs? - bootp.giaddr= dev-bootp.gateway; + bootp.giaddr= INADDR_ANY; according to git aboves line exits since quite some time, i'd say since at least Debian and Ubuntu integration. so i'd need a bit more evidence to merge such a patch. i'll test it next week on my side. thanks for the feedback! -- maks -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
