"ss" Parser not working correctly: Entries Missing

[megabert]

jc version: 1.25.2
python interpreter version: 3.10.9
ss utility, iproute2-5.9.0

ss-Parser seems not to be working correctly:

a) raw ss output

export LC_ALL=C;ss -tulpen | grep :443 | cut -c1-100
tcp   LISTEN 0      511                       1.2.3.43:443        0.0.0.0:*    users:(("apache2",pid...
tcp   LISTEN 0      511                       1.2.3.32:443        0.0.0.0:*    users:(("apache2",pid...
tcp   LISTEN 0      511                       1.2.3.31:443        0.0.0.0:*    users:(("apache2",pid...
...

b) resulting jc output

export LC_ALL=C;ss -tulpen | jc --ss | jq .|grep "[^0-9]443"

# no output at all

There should be three blocks like this one for port 443:

# export LC_ALL=C;ss -tulpen| jc --ss | jq '.[] | select (.send_q==8443)'

{
  "netid": "tcp",
  "state": "LISTEN 0",
  "recv_q": 16,
  "send_q": 8443,
  "local_address": "[::]",
  "local_port": "*",
  "peer_address": "users:((\"liveconfig/SRVR\",pid=3279783,fd=11),(\"liveconfig\",pid=3279782,fd=11)) ino:788096034 sk:2016 cgroup:/system.slice/liveconfig.service v6only",
  "peer_portprocess": "1 <->"
}

Hi there - thanks for reporting this. I'll have to see why the ss parser is skipping those lines.

This output seems a bit strange. For example, there is no space between Port and Process in the header. Even with a space added I still see parsing issues, so I'll need to take a closer look at what's going on here.
