2010-10-19 12:48:47 Which dhcp client for IPv4LL (link local / zeroconf) support?

I have been using dhcpcd-new successfully, but would now like to enable the automatic generation of a link-local address if DHCP fails. dhcpcd-new doesn't seem to do that. It appears that there are at least three other dhcp clients that would probably do that job: dhcpcd (not the "new" version), dhcpd(ISC), and dhclient. Can anyone recommend one of them or suggest a reason I might choose one over another? Thanks.
Steve
P.S. My only gripe with dhcpcd-new until now has been that if a network cable is not connected until after a unit is booted, it doesn't get an address unless I manually run "dhcpcd &" again. If any of the other options handle that in a better way that would be a advantage. Or maybe that is a job for netplug?

you probably would want to upgrade to the latest dhcpcd version

The version I have now reports the following:
root:~> dhcpcd --help
DHCP Client Daemon v.1.3.20-pl0

Location: www.phystech.com/download/
Usage: dhcpcd [-dknrBCDHPRT] [-l leasetime] [-h (hostname|-)] [-t timeout]
[-i vendorClassID] [-I ClientID] [-m dhcpRequests ] [-c filename]
[-s [ipaddr]] [-w windowsize] [interface]
I went to the web site mentioned in that message, < www.phystech.com/download/>. It appears that there is a newer version there (1.3.22-pl4), but I didn't find any mention in the man page or changelog there of support for IPv4LL, zeroconf, autoconfig or RFC 3927 (IPv4LL).
Mike, are you suggesting that the current version of the Blackfin uClinux distribution has IPv4LL support in dhcpcd-new?

i have no idea what IPv4LL is or what clients in the tree support it. if you cant find existing support, then you may have to upgrade.
the 4.x series is probably easier than 5.x:
