n2os-smb-client

This is a custom smb/cifs client with libsmb2 statically linked.

Building

FreeBSD version

Optional prerequisite: install kerberos if you want Kerberos support

cd /usr/ports/security/krb5
# (there should be a single Makefile in the folder)
sudo make install clean

git submodule update --init --recursive
cmake . -DCMAKE_BUILD_TYPE=Release
make
strip -s n2os_smb_client

A build script is provided in build.bsd.sh.

Linux version

docker run -it -v $(pwd):/n2os-smb-client debian:bullseye-slim /bin/bash
apt update
apt install -y build-essential upx-ucl cmake libssl-dev libkrb5-dev
cd /n2os-smb-client
cmake . -DCMAKE_BUILD_TYPE=Release
make
strip -s n2os_smb_client
upx --best n2os_smb_client

A build script is provided in build.linux.sh.

A Dockerfile is also provided. Build and usage examples are provided in the Dockerfile itself.

Kerberos support

To build with kerberos support, provided that the dependencies are met, just add to the cmake command-line -DBUILD_WITH_KRB5=true. For the Linux Dockerfile you can use the build parameter WITH_KERBEROS.

Usage

Usage is pretty simple. This client right now can just do four simple operations: ls, del, get and put.

Note that connection password can be passed using env variable N2OS_SMB_PASSWORD
