I try to execute the sample server in Occlum and client out of enclave. I find that they can connect successfully but the messages delivered by server in Occlum has some unreadable code.

Reproduce

Double containers:

You can reproduce using the following Dockerfiles:
The first one is Dockerfile for rats-server in Occlum:

#rats_server-Dockerfile
FROM docker.io/occlum/occlum:0.27.3-ubuntu20.04
RUN sed -i '2,2s/localhost:8081/sgx-dcap-server.cn-beijing.aliyuncs.com/g' /etc/sgx_default_qcnl.conf &&\
    sed -i '5,5s/#//' /etc/sgx_default_qcnl.conf &&\
    sed -i '5,5s/FALSE/TRUE/g' /etc/sgx_default_qcnl.conf
RUN echo "Downloading rats-tls" && \
    git clone https://github.com/inclavare-containers/rats-tls.git
WORKDIR /root/rats-tls
RUN cmake -DRATS_TLS_BUILD_MODE="occlum" -DBUILD_SAMPLES=on -H. -Bbuild &&\
    make -C build install

The second one is Dockerfile for rats-client in Occlum:

#rats_client-Dockerfile
FROM docker.io/occlum/occlum:0.27.3-ubuntu20.04
RUN sed -i '2,2s/localhost:8081/sgx-dcap-server.cn-beijing.aliyuncs.com/g' /etc/sgx_default_qcnl.conf &&\
    sed -i '5,5s/#//' /etc/sgx_default_qcnl.conf &&\
    sed -i '5,5s/FALSE/TRUE/g' /etc/sgx_default_qcnl.conf
RUN echo "Downloading rats-tls" && \
    git clone https://github.com/inclavare-containers/rats-tls.git
WORKDIR /root/rats-tls
RUN cmake -DBUILD_SAMPLES=on -H. -Bbuild &&\
    make -C build install

The run the commands below to obtain two running containers.

docker build -f rats_server-Dockerfile -t rats_test:sv0.1 .
docker build -f rats_client-Dockerfile -t rats_test:cv0.1 .
docker run -itd --name rte_server --privileged -v /dev/sgx_enclave:/dev/sgx/enclave -v /dev/sgx_provision:/dev/sgx/provision --net=host rats_test:sv0.1
docker run -itd --name rte_client --privileged --net=host rats_test:cv0.1

Enter the corresponding container and launch the server and client.

#rte_server
cd /usr/share/rats-tls/samples
rm -rf occlum_workspace_server
mkdir occlum_workspace_server
cd occlum_workspace_server
occlum init
cp ../rats-tls-server image/bin
cp /lib/x86_64-linux-gnu/libdl.so.2 image/opt/occlum/glibc/lib
cp /usr/lib/x86_64-linux-gnu/libssl.so.1.1 image/opt/occlum/glibc/lib
cp /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1 image/opt/occlum/glibc/lib
mkdir -p image/usr/local/lib
cp -rf /usr/local/lib/rats-tls image/usr/local/lib
occlum build
occlum run /bin/rats-tls-server -m -l debug -a sgx_ecdsa -v nullverifier

#rte_client
cd /usr/share/rats-tls/samples
./rats-tls-client -l debug -m -a nullattester -v sgx_ecdsa

You can obtain the similar output like the next two code boxes:

#rte_server

# Build rats-tls in sgx mode to get rats-tls-server running in enclave
cmake -DRATS_TLS_BUILD_MODE="occlum" -DBUILD_SAMPLES=on -H. -Bbuild
make & make install

# Backup sgx mode programs
cp -a /usr/share/rats-tls/samples /usr/share/rats-tls/samples-sgx

# Build rats-tls in host mode to get rats-tls-client running on host
cmake -DRATS_TLS_BUILD_MODE="host" -DBUILD_SAMPLES=on -H. -Bbuild
make & make install

# Have a test
cd /usr/share/rats-tls/samples-sgx
./rats-tls-server --attester sgx_ecdsa --verifier nullverifier -l debug -m &
