README.md

使用方法

依次运行/源代码编译

sudo bash ./init.sh
sudo ./ns-demo	#gcc main.c -o ..
备注：

ubuntu18.04LTS

默认使用 rootfs/bin/sh 添加bash支持需运行init.sh

<sys/capability.h> --> install libcap-devel

完成功能：

UTS,PID,MOUNT,USER,NET.

测试：

容器内运行C编写的SimpleHTTPServer,容器目录/SERVER/HTTPSVR

默认宿主机访问 容器lxcveth1:8080(169.254.1.2:8080)

从源代码编译HTTPSVR

gcc ./httpsvr.c --static -o HTTPSVR
已知问题：
  1. CLONE_NEWNET创建lxcveth0/1需要su.但与以普通用户运行容器相悖,造成parent root:container root的映射.权限过高
  2. 尝试sed 编辑/proc/$$/uid,gid 疑受CAP_SETUID 限制,改用C fileIO读写
