Tvheadend

Hi,

could REALLY use some help here.
I have a working clearos tvheadend setup but I am moving my old hardware to new hardware with Ubuntu 14.04 (LTS)

On my new machine I have changed /etc/dhcp/dhcp.conf to hold:

interface "p4p1" {
        request subnet-mask, time-offset, routers, domain-name-servers, host-name, domain-name,
                root-path, default-ip-ttl, broadcast-address, perform-mask-discovery, router-discovery,
                static-routes, nis-domain, nis-servers, ntp-servers, vendor-encapsulated-options;

        send dhcp-max-message-size 548;
        send vendor-encapsulated-options 03:09:61:6d:69:6e:65:74:31:34:30:04:05:66:69:73:79:73;
        send vendor-class-identifier "Aminoaminet140fisys";
        send dhcp-client-identifier 01:00:02:02:xx:xx:xx;
}

I have changed /etc/network/interface to hold:

auto p4p1
iface p4p1 inet dhcp
   hwaddress ether 00:02:02:xx:xx:xx
   vendor "Aminoaminet140fisys" 
   pre-up echo 2 > /proc/sys/net/ipv4/conf/p4p1/force_igmp_version
   pre-up echo 0 > /proc/sys/net/ipv4/conf/p4p1/rp_filter

And I created a script /etc/network/if-up.d/iptv

#!/bin/sh
# Check for specific interface if desired
# Adding additional routes on connection
route add -net 224.0.0.0 netmask 240.0.0.0 dev p4p1
route add -net 82.139.121.0 netmask 255.255.255.0 gw 10.30.252.1 dev p4p1

this results into: ifconfig >

p4p1      Link encap:Ethernet  HWaddr 00:02:02:xx:xx:xx  
          inet addr:10.30.255.130  Bcast:10.30.255.255  Mask:255.255.252.0

and route -n >

I have the following iptables -L -v:

Chain INPUT (policy ACCEPT 65312 packets, 45M bytes)
 pkts bytes target     prot opt in     out     source               destination         
 282K  378M ACCEPT     all  --  any    any     anywhere             base-address.mcast.net/4 

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         
    0     0 ACCEPT     all  --  any    any     anywhere             base-address.mcast.net/4 

Chain OUTPUT (policy ACCEPT 84010 packets, 43M bytes)
 pkts bytes target     prot opt in     out     source               destination

so far so good,
problem is that in TVHeadend I keep getting

2015-01-02 12:25:37.000 mpegts: udp://239.192.4.101(null) in IPTV - tuning on IPTV
2015-01-02 12:25:37.000 subscription: 0037: "scan" subscribing to mux, weight: 1, adapter: "IPTV", network: "IPTV", mux: "udp://239.192.4.101(null)", hostname: "", username: "", client: "" 
2015-01-02 12:25:52.000 mpegts: udp://239.192.4.101(null) in IPTV - scan no data, failed
2015-01-02 12:25:52.000 subscription: 0037: "scan" unsubscribing

where in my clearos (centos) setup this works (only difference is IP address that is assigned to my networkcard)
Could realy use some assistance as I am not able to get this right and it keeps me from turning of the old hardware

Thanks in advance,
Ruud.

Just for future reference in case somebody else is strungling to get it working. Just solved it.
the cullprit was in the rp_filter of the all interface.
changed my /etc/network/if-up.d/iptv with the following information:

#!/bin/sh
# Adding additional routes on connection
route add -net 224.0.0.0 netmask 240.0.0.0 dev p4p1
route add -net 82.139.121.0 netmask 255.255.255.0 gw 10.30.252.1 dev p4p1
echo 2 > /proc/sys/net/ipv4/conf/p4p1/force_igmp_version
echo 0 > /proc/sys/net/ipv4/conf/p4p1/rp_filter
echo 1 > /proc/sys/net/ipv4/conf/p4p1/forwarding

echo 2 > /proc/sys/net/ipv4/conf/p1p1/force_igmp_version
echo 0 > /proc/sys/net/ipv4/conf/p1p1/rp_filter
echo 1 > /proc/sys/net/ipv4/conf/p1p1/forwarding

echo 2 > /proc/sys/net/ipv4/conf/all/force_igmp_version
echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter
echo 1 > /proc/sys/net/ipv4/conf/all/forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward

and also put echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter in rc.local because it wouldn't stick.
everything working great now!

Great to read you got it working

My Setup is Ubuntu 14.04 and have IPTV on fibre from Concepts (Telford now)

I would like to migrate from DVB-C to IPTV
Can you help me with some basics ?
(my email address is iptv<at>concepts.nl)
