Debug CLI to magically create / delete a TCP session
The session ends up in established state, and is hand-crafted to look
like it was created by the builtin_server.
This will come in handy for injecting packets into tcp46-established,
along with ancillary debug CLI to adjust connection parameters.
Immediate applications include screwball window cases, out of order
segments, paws checking, and so on and so forth.
Debug CLI script:
loop create
set int ip address loop0 6.0.1.1/8
set int state loop0 up
set ip arp loop0 6.0.1.2 feed.face.babe
test tcp server
test tcp session
packet-generator new {
name tcp
limit 1
node ip4-input
size 100-100
interface loop0
no-recycle
data {
TCP: 6.0.1.2 -> 6.0.1.1
TCP: 11234 -> 1234
ACK window 2000
seqnum 0
acknum 0
incrementing 100
}
}
