远程连接的一些笔记

简介

主要是远程到远程服务器的一些用法

1. ssh配合xserver达到远程应用图像显示到本地
2. linux下smb文件共享

ssh+xserver

server配置

编辑/etc/ssh/sshd_config
修改下面的值

X11Forwarding yes
X11DisplayOffset 10

一条命令

sudo sed -i 's/#X11Forwarding yes/X11Forwarding yes/g' /etc/ssh/sshd_config;
sudo sed -i 's/#X11DisplayOffset 10/X11DisplayOffset 10/g' /etc/ssh/sshd_config;
sudo systemctl restart sshd;

无桌面的server

centos

yum install -y xorg-x11-xauth xorg-x11-utils xorg-x11-fonts-*

ubuntu/debian

sudo apt-get install -y x11-apps;

windows客户端

mobaxterm一把梭

mac客户端

先安装xquartz

brew cask install xquartz

然后修改配置文件/private/etc/ssh/ssh_config
个人感觉可以是/private/etc/ssh/ssh_config也可以是直接/etc/ssh/ssh_config
把ForwardX11 yes的注释取消
并且添加ForwardX11Trusted yes

这样也可以远程进行sublime text3进行编辑了

附带一个pwntools用的脚本

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from pwn import *
from binascii import *

BINARY_FILE = './pwn'
REMOTE = ('127.0.0.1', 10000)


def setup_connection():
    binary, libc, preload = None, None, False
    local_libc = '/lib/x86_64-linux-gnu/libc.so.6'
    task_libc = './libc.so.6'

    env = {}
    if args.PRELOAD:
        local_libc = task_libc
        env = {'LD_PRELOAD': task_libc}

    if args.BINARY:
        binary = ELF(BINARY_FILE)
        context.arch = binary.arch

    if args.REMOTE:
        if args.LIBC:
            libc = ELF(task_libc)
        s = remote(*REMOTE)
    else:
        if args.LIBC:
            libc = ELF(local_libc)
        
        s = process(BINARY_FILE, stderr=open('/dev/null', 'w+'), env=env)
        if args.GDB:
            context.terminal = ['gnome-terminal', '-e']
            breakpoints = [0x400001, 0x400002]  
            gdb.attach(s, exe=BINARY_FILE, gdbscript='\n'.join(['b *'+str(x) for x in breakpoints]))
            
    return s, binary, libc

if __name__ == '__main__':
    s, binary, libc = setup_connection()
    context.update(arch = 'amd64')

smb

过程

安装

sudo apt-get install samba

目录配置,最好用一个单独的目录并且chmod 777

[share]
      path = dir_path
      available = yes
      browseable = yes
      public = yes
      writable = yes

设置登陆用户

sudo touch /etc/samba/smbpasswd;
sudo smbpasswd -a smb;
sudo service smbd restart
