      There is a newer Version of the dhclient-script on the freebsd CVS Server.

      1.20.2.1.4.1 2010/06/14 02:09:06

      http://www.freebsd.org/cgi/cvsweb.cgi/src/sbin/dhclient/dhclient-script?f=u&only_with_tag=RELENG_8_1&logsort=date

      can you implement the this Version of the dhclient-script?

      I have an Issue with the current Version: For IPTV the ISP the Routes for the IPTV-Interface is set by DHCP, this Version is trying to set 255.255.255.255 as a GW.

            Build is:

            2.0-BETA4 (i386)
built on Sat Dec 4 02:44:21 EST 2010

            with dhclient-script in version:

            # $FreeBSD: src/sbin/dhclient/dhclient-script,v 1.4 2005/06/10 03:41:18 brooks Exp $

            I switched to the newest Version of this script. (Version motioned in my first post), my problems with IPTV while switching the channel are gone…

            I think in the older Version, the script is trying to set 255.255.255.255 as GW.

            Which log do you need?

              And try with the newer snapshot i made some changes to dhclient script regarding default gw.
              Otherwise we are same as freebsd since i synced some time ago.

                Sorry,

                with a newer build,

                2.0-BETA4 (i386)
built on Thu Dec 9 05:12:59 EST 2010 
```,

I have the same Issue. Switching the Channels with IPTV is extremely slow, as if the Routes are not set via DHCP.

Here the System Logs with the original dhclient script:

                    So, I made the change manually.

                    But unfortunately my Issue isn´t solved. When I return to the script from the CVS Server, the Issue is gone.

                    Do you need further infos, tests or logs?

                    Thx!

                          I have the Issue with IPTV.

                          FIrst 10 sec goes via UDP Stream, after 10 seconds the stream switch to Multicast. The routes for the UDP-Stream (and maybe other services) are set via DHCP.

                          If the routes aren´t set, you get the first 10 seconds a freeze image and after switching to Multicast, everything is fine. So if you switch the channels you have to wait 10 sec, before you can watch TV.

                          So, with the original dhclient-script, the routes are set, but the behavior is like the routes aren´t set. I don´t know exactly, why. The routes aren´t different to the CVS script. Bute with the script from the CVS server, the first 10 sec are working fine.

                            That might be because or PBR but i cannot really tell.

                              Hi,

                              I also have this Problem with this script and IPTV. Why is it so difficult for you to use the new script from the server. With this script our problems are gone and you do not have to debug something.
                              Greetings

                                          I second the request to update the dhclient-script!

                                          Everyone using T-Home IPTV in Germany is going to have issues if its not updated…

                                          To clarify this problem:

                                          T-Home is using vlans to seperate Web and IPTV traffic. The Web traffic is using PPPoE on Vlan 7, the IPTV traffic is using dhcp on Vlan8.
                                          IPTV is using unicast for the first 10 seconds of the stream and then switches to multicast which is working very good with the new igmp proxy(which is still spamming the main systemlog making it unusable btw!!!)

                                          The problem which is fixed by the new dhclient script is that the old script sets a gateway to 255.255.255.255 which is useless and causes the first 10 seconds of unicast to fail which in turn makes switching channels very slow because the STB has to wait for the multicast to begin(1-2 seconds...)

                                          This is a packetcapture for the iptv interface dhcp reply:

                                          07:30:37.027153 00:19:db:e3:89:6a > ff:ff:ff:ff:ff:ff, ethertype IPv4 (0x0800), length 342: (tos 0x10, ttl 16, id 0, offset 0, flags [none], proto UDP (17), length 328)

                                          With the original script i got this for the Interface in

                                          System:Gateways:

                                          
Name 	           Interface 	Gateway 	        Monitor IP 	        Description

GW_OPT3 	        IPTV 	        255.255.255.255 	255.255.255.255 	Interfaceopt3dynamic gateway

                                          With the script from the cvs server i get:

                                          
Name 	   Interface 	    Gateway 	        Monitor IP 	        Description

GW_OPT3  IPTV  	       dynamic 	        dynamic 	        Interfaceopt3dynamic gateway

                                          Maybe this informations is useful for you…

                                          Both scripts however create the same routing entrys so this is aparently not a routing issue…:
