sleep 2
ns2b ip addr show
sleep 3
say ,
nl
say pasta copies addresses from the host
hl NS2
sleep 2
nl
say - slirp4netns uses
em tap0
say as interface name
hl NS1
sleep 2
say , pasta
nl
say takes an interface name from the host
hl NS2
sleep 2
nl
say - same for routes:
ns1b ip route show
sleep 3

nl

hl NS1
sleep 2

ns2b ip route show

nl
say Let's check connectivity...
sleep 2

nl
nl
say What about performance, you might ask.
nl
say For simplicity, we'll measure between init
nl
say namespace (the "host") and container. To do
nl
say that, we need to allow the container direct
nl
say access to the host, which needs an extra option
nl
say in slirp4netns. Let's restart that container,
nl
say while also mapping ports for iperf3 and neper.
nl
sleep 3
ns1 exit
ns1b podman run --rm --net=slirp4netns:allow_host_loopback=true,enable_ipv6=true -p 5201-5202:5201-5202/tcp -p 5201-5202:5201-5202/udp -ti alpine sh
sleep 5
nl
nl
say pasta allows that by default, so we wouldn't need
nl
say to touch the container using pasta, but let's
nl
say take the chance to look at passing extra options
nl
say there as well.
nl
nl
ns2 exit
say Options after '--net=pasta:' are the same as
nl
say documented for the command line of pasta(1).
nl
say For example, we can enable packet captures
sleep 3
ns2b ./bin/podman run --net=pasta:--pcap,demo.pcap --rm -ti alpine sh
sleep 5
say ,
nl
say and generate some traffic we can look at.
nl
sleep 2
ns2b wget -O - lameexcu.se
sleep 2
hostb tshark -r demo.pcap tcp
sleep 5
nl
say But back to performance now. By the way,
nl
say pasta can also forward ports through the
nl
say loopback interface for improved throughput.
nl
say Let's configure that.
nl
sleep 2
ns2b exit
sleep 1
ns2b ./bin/podman run --net=pasta:-T,5213-5214,-U,5213-5214 -p 5203-5204:5203-5204/tcp -p 5203-5204:5203-5204/udp --rm -ti alpine sh
sleep 5
nl
say In slirp4netns mode, Podman enables by
nl
say default the port forwarder from 'rootlesskit'
nl
say for better performance.
nl
say However, it can't be used for non-local
nl
say mappings (traffic without loopback source
nl
em and
say destination) because it doesn't preserve
nl
say the correct source address as it forwards
nl
say packets to the container.
sleep 3
nl
nl
say We'll check non-loopback mappings first for
nl
say both pasta and slirp4netns, then restart the
nl
say slirp4netns container with rootlesskit and
nl
say switch to loopback mappings. pasta doesn't
nl
say have this limitation.
nl
nl
say One last note: slirp4netns doesn't support
nl
say forwarding of IPv6 ports (to the container):
nl
say github.com/rootless-containers/slirp4netns/issues/253
nl
say so we'll skip IPv6 tests for slirp4netns as
nl
say port forwarder (on the path to the container).
sleep 5

sleep 3
nl
nl
say We'll use iperf3(1) for throughput
sleep 2
ns1b apk add iperf3 jq bc
ns2b apk add iperf3 jq bc

say and static
nl
say builds of neper (github.com/google/neper) for
