- ping
- ping6 ::1 ... should always work
- ping6 -b 70000 -s 68000 Clientv6 jumbo packets

| IPv6 Connectivity Tests
|
- ip6fw -a list
- netstat -s -p ip6
- telnet ::1 80 === do NOT use
- ssh -6 -l LocalUser ::1
- dig +short ipv6.google.com @ns.IPv6-Cloud.org AAAA
- host -t AAAA ipv6.google.com
- tracepath6 www.kame.net
- traceroute6 www.kame.net
- nmap -sT localhost
- nmap -6 -sT ::1
- sockstat -4
- sockstat -6
- tcpdump -t -ni eth0 -s 512 -vv ip6 or proto ipv6
- tcpdump -ni lo0 icmp6 -- for watching ping6 ::1
- tcpdump -ni gif0 icmp6 -- for static ipv6 over ipv4 tunnels
- tcpdump -ni stf0 icmp6 -- for 6to4 tunnels

| Bandwidth Tests

- Change your kernel send and receive buffer sizes
- Change application ( iperf/socat/etc) send and receive buffer sizes
- plain ole ping - ping6
- flood the gigEnn-T3 ( 100Mbit/s ) wire .. upper limits at 65Mbit/s + overhead
- Server# ping -s 62000 -i 0.015 192.168.242.25 > /dev/null
- Client# ping -s 62000 -i 0.015 192.168.241.14 > /dev/null
- ServerIPv6# ping6 -b 70000 -s 60000 -i 0.001 ClientIPv6
- ClientIPv6# ping6 -b 70000 -s 60000 -i 0.001 ServerIPv6
- Netperf.org
- reciever# netserver -6 -p 1111
- sender# netperf -6 -p 1111 -H receiver ... tcp or udp
- SourceForge.net iperf ... flood the network
- IPv4 Bandwidth
- serverIPv4# iperf -w 2048k -s
- clientIPv4# iperf -w 2048k -c ServerIPv4Address -P 10
- IPv6 Bandwidth
- serverIPv6# iperf -w 2048k -s -V
- clientIPv6# iperf -w 2048k -c ServerIPv6Address -V -P 10
- hep.man.ac.uk UDPmon .. nice graphs too
- Request - Response Latency

- nc6 -6 -v -n -z -w 1 192.168.1.2 1-1000
- Dest-Unreach.org socat .. flood the wire ..
- Transfer a file with socat and udp
- recv# socat - UDP-LISTEN:11111
- send# cat any-file | socat - UDP:Recv:11111
