hey I was wondering if anybody could tell me why on my vm there's multicast
ping to 224.0.0.1
what is the purpose of that
Guest43587: do you have something like avahi installed?
no
I dont use that kinda stuff
you're talking about like zeroconf dns and ndp right
That's what she said!!
yeah
yeah I use nbp for ipv6 I think because I have the whole /48 routed but I think thats it
na, ipv6 multicast doesn't use the ipv4 multicast addresses...
BryceBot: no
Oh, okay... I'm sorry. 'you're talking about like zeroconf dns and ndp right'
lol ant
erratic: Since 224.0.0.1 is the generic "all hosts" address, it's not easy to say what it's being used for. Your best bet is a tcpdump of the traffic, as well as to see what's listening with a command like lsof or netstat
erratic: You might see (as most Linux users do) a simple "igmp query v2" packet. This is common in default Linux configurations and as I understand it, it's just the kernel looking to see if there's an upstream IGMP router/forwarder
did the congestion issues go away in the end?
they still appear on my graphs every now and again
not as bad as it was though
cool.
