    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    TitanHide

    TitanHide

    Hiding kernel-driver for x86/x64

    TitanHide is an open-source Windows kernel driver designed to conceal debugging activity from selected processes during software analysis. It operates at the kernel level by intercepting specific Windows system functions and modifying information returned to applications. This approach helps reverse engineers examine software that implements debugger detection and anti-debugging protections. The driver can conceal debugging flags, debugger ports, debugging objects, and kernel debugger information. It also provides mechanisms for protecting hardware breakpoints and handling certain debugger-related exceptions. TitanHide supports 32-bit and 64-bit Windows environments and includes integration with debugging tools such as x64dbg. Its installation requires advanced system configuration, and the project recommends using isolated virtual machines.

    shadowsocks-libev

    shadowsocks-libev

    Bug-fix-only libev port of shadowsocks

    Shadowsocks-libev is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. Shadowsocks-libev is written in pure C and depends on libev. It's designed to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible. Snap is the recommended way to install the latest binaries. You can build shadowsocks-libev and all its dependencies by script. The latest shadowsocks-libev has provided a redir mode. You can configure your Linux-based box or router to proxy all TCP traffic transparently, which is handy if you use an OpenWRT-powered router. Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user. We strongly encourage you to install shadowsocks-libev from jessie-backports-sloppy.
