Bug: Traceroute ignored IPs when multiple IPs on hop

[poclecoqq]

Description: When a hop in a traceroute has many IPs, the parser only considers the first IP it sees and ignores the others.

Given a traceroute with a line such as:

12  http://as15169-10g-sk1.sthix.net  (192.121.80.47) [*]  10.010 ms 72.14.196.42 (72.14.196.42) [AS15169]  9.182 ms  44.983 ms

we would expect jc to return (for that hop/line):

{
            "hop": 12,
            "probes": [
                {
                    "annotation": null,
                    "asn": null,
                    "ip": "192.121.80.47",
                    "name": "http://as15169-10g-sk1.sthix.net",
                    "rtt": 10.01
                },
                {
                    "annotation": null,
                    "asn": 15169,
                    "ip": "72.14.196.42",
                    "name": "72.14.196.42",
                    "rtt": 9.182
                },
                {
                    "annotation": null,
                    "asn": 15169,
                    "ip": "72.14.196.42",
                    "name": "72.14.196.42",
                    "rtt": 44.983
                }
            ]
},

instead, it currently returns (please compare the IP, name, and ASN fields):

        {
            "hop": 12,
            "probes": [
                {
                    "annotation": null,
                    "asn": 15169,
                    "ip": "192.121.80.47",
                    "name": "http://as15169-10g-sk1.sthix.net",
                    "rtt": 10.01
                },
                {
                    "annotation": null,
                    "asn": 15169,
                    "ip": "192.121.80.47",
                    "name": "http://as15169-10g-sk1.sthix.net",
                    "rtt": 9.182
                },
                {
                    "annotation": null,
                    "asn": 15169,
                    "ip": "192.121.80.47",
                    "name": "http://as15169-10g-sk1.sthix.net",
                    "rtt": 44.983
                }
            ]
        },

The example above is an extract from ./tests/fixtures/generic/traceroute1.out. I have already fixed that bug in a forked repository.

Thanks for reporting this. I created a PR from your fork and will take a look at merging that in.

This is fixed in the dev branch and will make it into the next release.

You can test by copying the parser file above into your parser plugin folder:

• Linux/unix: $HOME/.local/share/jc/jcparsers
• macOS: $HOME/Library/Application Support/jc/jcparsers
• Windows: $LOCALAPPDATA\jc\jc\jcparsers

Fixed in v1.25.3
