From 28a6afe975c65ee25e5739b1d52eb24b2a8f27c9 Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Mon, 20 Mar 2006 17:37:00 +0000 Subject: Roy Walker writes: Here is a patch against the current subversion repository, that makes udhcpc have an adjustable timeout. Works for both foreground and before it drops to the background. This brings it more in-line with ISC dhcpc. Use like so: udhcpc --timeout=10 ... or udhcpc -T 10 ... Still shooting for 1.1.1 this month? Would really be great if you could get this in that release.
