this repo has been moved to my other account which is dedicated to C++ architecture: https://github.com/buildingcpp/network
lots of logging, documentation and error handling to be added
The multicast example relies on the ip address 239.0.0.1
. It will not work without it.
If you want to run this example check for the 239.0.0.1
using ip address
to list
all interfaces and ip addresses.
Example:
~$ ip address
<SNIP>
3: wlp5s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
inet 192.168.1.161/24 brd 192.168.1.255 scope global dynamic noprefixroute wlp5s0
valid_lft 84299sec preferred_lft 84299sec
</SNIP>
To add 239.0.0.1
: (in my case to interface wlp5s0
)
~$ sudo ip addr add 239.0.0.1/32 dev wlp5s0
Verify that 239.0.0.1
now exits:
$ ip address
<SNIP>
3: wlp5s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
inet 192.168.1.161/24 brd 192.168.1.255 scope global dynamic noprefixroute wlp5s0
valid_lft 84116sec preferred_lft 84116sec
inet 239.0.0.1/32 scope global wlp5s0 <----- ip was added
valid_lft forever preferred_lft forever
</SNIP>
The multicast demo should now (hopefully) function correctly.
To remove 239.0.0.1
: (in my case from interface wlp5s0
)
~$ sudo ip addr del 239.0.0.1/32 dev wlp5s0
