Problem with the emanesh command

[James-Sloop]

I am trying to work with EMANE and would like to be able to modify the unicastrate and multicastrate of the IEEE802.11abg model at runtime. When I tried to use $ emanesh node-1 set config nems mac unicastrate=10 I get an error. I get the same error when I try to run emanesh node-1 without any other parameters.

jcsloop in ~:emanesh node-1

I am certain my emane version is 1.5.1:

jcsloop in ~:emane --version
1.5.1
jcsloop in ~:

I am not sure what could be causing this problem. I have tried to solve the problem myself by making sure emanesh has been installed correctly:

jcsloop in ~:which emanesh
/usr/bin/emanesh
jcsloop in ~:

I have also confirmed emanesh is in my $PATH. I have tried adding the path to emanesh into my $PYTHONPATH and that didn't solve the issue either. Both of my coworkers working with me are having the same problem where we are just unable to use emanesh which has made working with EMANE at runtime quite problematic. Other than emanesh not working everything else has been working normally so I don't think it is a problem with my EMANE installation. My coworkers and I are all using Ubuntu 22.04 with EMANE version 1.5.1. Is there a known fix for this issue?

How did you install emane?

[James-Sloop]

I cloned it from https://github.com/adjacentlink/emane.git when I was installing CORE. I used these installation instructions:

# install emane
cd ~/Documents
wget https://github.com/protocolbuffers/protobuf/releases/download/v3.19.6/protoc-3.19.6-linux-x86_64.zip
mkdir protoc
unzip protoc-3.19.6-linux-x86_64.zip -d protoc
git clone https://github.com/adjacentlink/emane.git
cd emane
./autogen.sh
./configure --prefix=/usr
make -j$(nproc)
sudo make install
cd src/python
make clean
PATH=~/Documents/protoc/bin:$PATH make
sudo /opt/core/venv/bin/python -m pip install .

Everything but emanesh is currently working fine and I talked to the people at CORE and they said this is an EMANE issue unrelated to CORE.

Your issue is more than likely related to the way you installed emane. CORE is a 3rd party tool that we do not use or support. My suggestion would be to install emane from debs on Ubuntu 22.04.

I did not say this was an EMANE issue, but as noted above. An issue with how you have installed EMANE currently.

Ok I will try installing EMANE a different way and see if that fixes the issue.
