Hello,
Can UDPcast be configured to "try harder/longer" to obtain a DHCP lease? We have spanning tree running on our switches and updcast always fails to obtain a lease on the first three attempts, then manually telling it to try again always results in success. This defeats the "preconfigured" setup.
Looking at the docs for udhcpc, I see:
-T,--timeout=N Try to get a lease for N seconds (default 3)
Could you bump this up by default to say 10 seconds (or have it tunable on the cast-o-matic)?
Thanks, Dax Kelson Guru Labs
BTW, the mailman page for this list is giving a "500 Internal Server Error".
I have been having the same issue with not receiving a DHCP response in time. I too, would appreciate it if the default value were raised or made tunable with cast-o-matic. Thanks, Matt Mulsow

I do not think, that the Spanning Tree Protocol is the reason. Maybe the "Portfast" setting on the Switch? The Port for the dhcp-connection (at boot time, without portfast) is to slow (port on the switch is not up, while asking for the lease). (sorry for my english)
Greatings.

I've now bumped it to 11 seconds (in order to take some slack...), and noticed that it actually retries 3 times (giving 33 seconds for the switch to react)
