dhcpcd-discuss

Hi Roy,

Thanks to you for looking into this issue!

dhcpcd-3.2.3     <-- definetly has the problem (used with OpenSUSE 11.0, 11.1, 11.2, 11.3 and Factory)
dhcpcd-1.3.22pl4 <-- fine (used with SuSE Linux Enterprise Server 9 and 10)
dhcpcd-5.2.9     <-- does not work as a drop in replaceemnt with OpenSUSE 11.0 or 11.3 and
                     therefore I just made some source code checks. It looks to me like
                     this uptodate version has the same problem. (E.g. it does not differ between the different type
                     of DHCP REQUESTs most of them are broadcasts though a renewal must be a unicasdt directly to the DHCP server
                     or to the gateway in case the dhcp server is in another network). Though I might be wrong here.

I am also not sure how to test with dhcpcd-5.2.9 as according to the documentation the semantics of "dhcpcd -n" has changed.

I also created a bug report for SuSE https://bugzilla.novell.com/show_bug.cgi?id=657402 which contains detailed instructions for reproducing the problem and last but not least a trace from wireshark https://bugzilla.novell.com/attachment.cgi?id=403342 .
