Hi @causimmi you are right, I've been able to reproduce the issue on the latest VM rose 2.7

we will try to fix the issue and let you know soon...

causimmi commented 2 years ago

I test that socket is not binded by sock.bind(addr) in

File "/home/rose/.envs/controller-venv/lib/python3.8/site-packages/urllib3-1.26.5-py3.8.egg/urllib3/util/connection.py", line 86, in create_connection
sock.connect(sa)

and some HTTP message is not received correctly

cscarpitta commented 2 years ago

Hi @causimmi, we fixed this problem in netgroup/rose-srv6-control-plane#90.

The problem was caused by a change in the v2.7 version of the ROSE VM.

By default, the controller attempted to connect to an ArangoDB database, which would cause a crash if the controller was started while ArangoDB was not running.

However since ArangoDB is only required for a few use cases, in netgroup/rose-srv6-control-plane#90 we changed the default controller configuration by disabling persistence on ArangoDB and we added instructions to enable persistence to rose-srv6-tutorial-part-2-control-plane.

Please run the update script that you can find on the Desktop of the ROSE-VM to pull the last changes.

Let me know if you run into any other problems.

Regards, Carmine

Hello Carmine,

First of all, I really appreciate that you and your team for the excellent work! This is so useful for students and researchers.

I had the same error message after I ran "bash starter.sh" using the ROSE VM I downloaded 1.5 years ago. I found out this blog and re-downloaded v2.7, but had the same problem. I am wondering if I could just make a few changes based on your fixes. If so, do you have those changes or what file(s) I should change?

BTW, when I ran

cd /home/rose/workspace/rose-srv6-control-plane/control_plane/apps/apps/cli

There is no starter.sh file in the directory. Is is related to the previous problem?

Thanks and regards, Chung

Hi @chlungwoo, please try to run the update script located on the Desktop of the ROSE-VM.

This script updates all the components installed in the ROSE-VM and creates the missing starter.sh script in /home/rose/workspace/rose-srv6-control-plane/control_plane/apps/apps/cli.

Thank you! I will try it later.

Hi Carmine,

I ran the update and starter.sh was available. But there was an error at line 51 of "cli.py":

Traceback (most recent call last): File "cli.py", line 51, in from apps.cli import srv6_cli, srv6pm_cli, topo_cli File "/home/rose/workspace/rose-srv6-control-plane/control_plane/apps/apps/cli/srv6_cli.py", line 38, in from apps.nb_grpc_client import utils as grpc_utils File "/home/rose/workspace/rose-srv6-control-plane/control_plane/apps/apps/nb_grpc_client/utils.py", line 40, in from nb_commons_pb2 import (STATUS_SUCCESS, File "/home/rose/workspace/rose-srv6-control-plane/control_plane/nb_protos/gen_py/nb_commons_pb2.py", line 33, in _descriptor.EnumValueDescriptor( File "/home/rose/.envs/srv6-apps-venv/lib/python3.8/site-packages/google/protobuf/descriptor.py", line 755, in new _message.Message._CheckCalledFromGeneratedFile() TypeError: Descriptors cannot not be created directly. If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0. If you cannot immediately regenerate your protos, some other possible workarounds are:

  1. Downgrade the protobuf package to 3.20.x or lower.
  2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

Any more update needs to be run? Thanks again!

Hi @lungwoo,

By downgrading the protobuf to 3.12.0 worked for me (don't forget to be in the correct virtual environment).
