Unable to parse % traceroute -n;

[zstyblik]

Hello,

it seems that parsing of % traceroute -n; output isn't supported which is a pity :/

Traceback (most recent call last):
  File "traceroute.py", line 28, in <module>
    main()
  File "traceroute.py", line 24, in main
    traceroute = trparse.loads(out)
  File "venv/local/lib/python2.7/site-packages/trparse.py", line 135, in loads
    rtt = float(probes_data[i+2])
ValueError: invalid literal for float(): 108.170.245.49

A-ha, problem is in traceroute's output:

 8  72.14.220.74  3.792 ms  2.809 ms  3.774 ms
 9  108.170.245.33  4.922 ms 108.170.245.49  4.940 ms 108.170.245.33  9.219 ms

I know it's a dirty fix, but it works:

            elif RE_PROBE_NAME.match(probes_data[i]):
                # Matched a name, so next elements are IP and rtt
                name = probes_data[i]
                ip = probes_data[i+1].strip('()')
                j = i + 1
                while j < len(probes_data):
                    if len(probes_data[j].split('.')) != 2:
                        probes_data.pop(j)
                    else:
                        j += 1

                rtt = float(probes_data[i+2])
                i += 3

... although, it breaks annotations and RTT ends up in the place of annotation. Back to zero.

Same problem here.

The library supposes that the output is in format HOP NAME (IP) PROBES:

 1  192.168.0.1 (192.168.0.1)  1.349 ms
 2  3-161-45-187.static.in-addr.vialink.com.br (187.45.161.3)  4.803 ms
 3  192.168.149.1 (192.168.149.1)  6.985 ms
 4  49-170-45-187.static.in-addr.vialink.com.br (187.45.170.49)  6.404 ms
 5  65-161-45-187.static.in-addr.vialink.com.br (187.45.161.65)  9.264 ms

Only IP output (HOP IP PROBES) is not currently supported:

 1  192.168.0.1  3.860 ms
 2  187.45.161.3  2.863 ms
 3  192.168.149.1  9.664 ms
 4  187.45.170.49  8.769 ms
 5  187.45.161.65  10.631 ms

I don't know if this is a simple fix (the traceroute output can have ! annotations and it complicates things). I'll try to fix it and, if I can do this, propose a patch to the project owner.

I realized two things:

1. @lbenitez000 doesn't answer issues from this project since Dec 2, 2016. Last commit was from Jan, 2017. Is this project still maintained? @lbenitez000, I can help you if you need.
2. This project is very similar to https://github.com/ckreibich/tracerouteparser.py/
   • The last project doesn't exist in Pypi (to be installed with pip). This is way I'm using this one;
   • This project imports cStringIO, although its not used. The project from ckreibich also imports this module (and uses it). So, is this project based somehow in the ckreibich traceroute parser?

The new version, v0.3.0, still doesn't support traceroute -n outputs.

[harendra247]

To make traceroute -n work please use the following

RE_PROBE_NAME_IP = re.compile(r'(\S+)\s+(?:\((\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})|([0-9a-fA-F:]+)\))*')

probe_ip = probe_name_ip_match.group(2) or probe_name_ip_match.group(3) or probe_name
