hsanet / reverse-traceroute Goto Github PK

I understand that using --transmit has some security implications. Thus there is a prompt to ensure that the user needs to make an informed decision.

I see a use case for some kind of batch mode. I.e. someone who doesn't want to be prompted for approval.

I can imagine to have some --force-transmit or --transmit -y flag.

Using echo "yes" | augsburg-traceroute --transmit will do the same -- which may be considered as argument pro and contra at the same time.

Error:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
poetry 1.1.12 requires keyring<22.0.0,>=21.2.0; python_version >= "3.6" and python_version < "4.0", but you have keyring 23.5.0 which is incompatible.
poetry 1.1.12 requires packaging<21.0,>=20.4, but you have packaging 21.3 which is incompatible.

I only made a short test up to now but the client seems to work for the first test at least in forward direction.

In reverse direction I'm getting:

Virtual-Machine:~/reverse-traceroute/client$ sudo augsburg-traceroute reverse udp multipath d001.eu.prod.t300.ter.int.amazonvideo.com
[sudo] password for tim: 
INFO:src.client:Determined traceroute target: 52.84.106.102
ERROR:src.client:The target did not respond to the reverse traceroute probe.
Virtual-Machine:~/reverse-traceroute/client$ sudo augsburg-traceroute reverse tcp multipath d001.eu.prod.t300.ter.int.amazonvideo.com
INFO:src.client:Determined traceroute target: 52.84.106.84
ERROR:src.client:The target did not respond to the reverse traceroute probe.

But that seems to be something connected to the amazon servers.

When using the --transmit flag one gets the following prompt:

Do you want to proceed [Yes/No]:

The capital letters indicate (to me) that it's enough to type y.
Only after looking into the code, I found that I have to type yes.

I suggest to accept y as a positive answer.

For every hop the following messages are repeated when running the client on a host without a configured broadcast address (e.g. when only a /32 is assigned to the interface). This is very noisy and not required.

I tried to compile and run the server on Ubuntu 20.04.
As indicated by the requirements, I installed linux-image-virtual-hwe-20.04 and thus kernel 5.15.0.

After running bash build_docker.sh I got a binary, but I couldn't execute it:

./augsburg-traceroute-server: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./augsburg-traceroute-server)

I think, it's fair to say that running the server requires Ubuntu 22.04 (or maybe later).

To improve public usability I'd suggest moving ENDPOINTS to a CSV file and store operationally relevant information.

Proposal:

DNS;ip4;ip6;ASN;contact
reversetraceroute.globalways.net;94.186.162.74;2a02:c98:1040:5400::6;48918;[email protected]

This issue highlights a problem in an earlier version and has already been fixed.
If you are heaving this issue, consider fetching the latest server version.

When tracing back from certain endpoints, traces report an Round-Trip-Time of zero across all hops.
This issue arised as the server used packet metadata to retrieve the timestamps needed for RTT computations.
On some machine, these timestamps were not initialized.
The problem was resolved by calling a function to retrieve the timestamps instead of relying on packet metadata.

Hi guys,
after the installation process finished, the service failed to run on Debian11.
I know that Debian11 is not the recommended OS for the setup, but maybe we can find a way to get it running.

System:
~# cat /etc/debian_version

~# uname -a
Linux 5.10.0-19-amd64 #1 SMP Debian 5.10.149-2 (2022-10-21) x86_64 GNU/Linux

Hi,

I just wanted to share that it is possible to use the compiled build using docker (see README.md).
I successfully built a firmware from Openwrt master branch - x86_64 just by building the LLVM toolchain which includes clang-15.

• Advanced configuration options (for developers) --->
  BPF toolchain (Build LLVM toolchain for eBPF) --->
  Build LLVM toolchain for eBPF

You can copy the following binary (v6 and v4) to run the server:

augsburg-traceroute-server-v6
augsburg-traceroute-server-v4

Thank you for your work. I hope to see the draft as RFC and implemented across multiple OS/vendors as an additional feature.

The server fails to start with the following error at the bottom of the output:

-- END PROG LOAD LOG --
libbpf: prog 'prog': failed to load: -13
libbpf: failed to load object 'traceroute'
