Unable to Launch freeRouter control plane along side TOFINO P4 dataplane from [ #004 ] - Cookbook #2

Open Mikkel-Rahbek opened 1 year ago

Mikkel-Rahbek commented 1 year ago

We have tried to follow the [ #004 ] - Cookbook guide https://wiki.geant.org/pages/viewpage.action?pageId=148084243 and we have the following 2 problems: Problem 1: Launching the command ./pcapInt.bin veth251 22709 127.0.0.1 22710 127.0.0.1 gives us the following error ./pcapInt.bin: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.34' not found (required by ./pcapInt.bin). When we issue the command: "ldd --version" we have version 2.31. Problem 2: At the final step, where we launch RARE bf_forwarder.py with the following command: "./bf_forwarder.py --ifmibs-dir ~/rare-run/mibs/ --ifindex ~/rare-run/snmp/ifindex". We get the error: Traceback (most recent call last): File "./bf_forwarder.py", line 21, in from rare.bf_gbl_env.cst_env import File "/rare/bfrt_python/rare/bf_gbl_env/cst_env.py", line 1, in from .var_env import File "/rare/bfrt_python/rare/bf_gbl_env/var_env.py", line 26, in import bfrt_grpc.client as gc ModuleNotFoundError: No module named 'bfrt_grpc' It seems like it has something to do with missing libraries in python as this path does not exists in our vm /lib/python*/site-packages/tofino/bfrt_grpc/ (not for python3.8 or python3.9)

Problem 1:

Which OK are you using ? The blog article is quite old but should still be relevant regarding the latest distribution. Latest distribution has switched to recent libc such as Debian SID. I suggest you download using:

wget www.freertr.org/rtr-`uname -m`.tar

and use Debian SID.

If you don't want to use prebuild, you would need to compile pcapInt.bin Before compilation please make sure you have libpcap-dev package installed

git clone https://github.com/rare-freertr/freeRtr.git
cd freeRtr/misc/native
./c.sh

then navigate to ../../binTmp you should see pcapInt.bin for your platform.

Problem 2:

Seems to show that you your INTEL SDE environment is not set properly. (bf_forwarder.py does not find grpc client.py in SDE library) In that case I would refer to INTEL SDE documentation and try to write a dummy python script that yield package within bfrt_grpc folder. Also I would suggest you use latest Debian SID so that python3 is standard.

Now, I suggest you use latest INTEL SDE (e.g 9.12.x) as it is more python3 friendly

Hey Frederic thank you for your answer. We have installed Debian SID, which helped us solve the issue about the incorrect glibC version. It now works fine. :) We fixed problem 2, but now we would like to create a network topology to test a basic forwading, and using this guide: image As seen on this picture: SudoMake

it seems like it is unable to run the 'make' command. Any idea

Thank you very much
