Repair TimeMachine Backup

  1. Mount timemachine volume from Finder.
  2. Unlock Target Machine's Backup sparsebundle.
    sudo chflags -R nouchg /Volumes/{TimeMachine Volume Name}/{Target Machine's Name}.sparsebundle
  3. Attach sparsebundle then Listing Backup Volume.
    hdiutil attach -nomount -noverify -noautofsck /Volumes/{TimeMachine Volume Name}/{Target Machine's Name}.sparsebundle
  4. Repair backup volume.
    fsck_hfs -drfy /dev/disk2s2
  5. Detach backup sparsebundle.

朴素VPN:一个纯内核级静态隧道

朴素VPN:一个纯内核级静态隧道

由于路由管控系统的建立,实时动态黑洞路由已成为最有效的封锁手段,TCP连接重置和DNS污染成为次要手段,利用漏洞的穿墙方法已不再具有普遍意义。对此应对方法是多样化协议的VPN来抵抗识别。这里介绍一种太简单、有时很朴素的“穷人VPN”。

朴素VPN只需要一次内核配置(Linux内核),即可永久稳定运行,不需要任何用户态守护进程。所有流量转换和加密全部由内核完成,原生性能,开销几乎没有。静态配置,避免动态握手和参数协商产生指纹特征导致被识别。并且支持NAT,移动的内网用户可以使用此方法。支持广泛,基于L2TPv3标准,Linux内核3.2+都有支持,其他操作系统原则上也能支持。但有两个局限:需要root权限;一个隧道只支持一个用户。

朴素VPN利用UDP封装的静态L2TP隧道实现VPN,内核XFRM实现静态IPsec。实际上IP-in-IP隧道即可实现VPN,但是这种协议无法穿越NAT,因此必须利用UDP封装。内核3.18将支持Foo-over-UDP,在UDP里面直接封装IP,与静态的L2TP-over-UDP很类似。

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Simple Sentry docker-compose.yml
  1. Download docker-compose.yml to dir named sentry
  2. Change SENTRY_SECRET_KEY to random 32 char string
  3. Run docker-compose up -d
  4. Run docker-compose exec sentry sentry upgrade to setup database and create admin user
  5. (Optional) Run docker-compose exec sentry pip install sentry-slack if you want slack plugin, it can be done later
  6. Run docker-compose restart sentry
  7. Sentry is now running on public port 9000
