    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.

    JRF

    Java Remote File - RemoteInputStream and RemoteOutputStream.

    JRF is a client/server application that allows to extend local storage to other computers running the JRF Server. It has been designed for ultra-simplicity, **not for security!** It does not request for authentication when accessing files on a remote server, nor does it prevent access to files or directories. It has been designed for already-secured networks (e.g. LANs or inside VPNs), where file-sharing setup is tedious (or impossible). Basic access configuration/restriction should be performed on the OS, by changing rights of the user running the JRF Server. It is like an insecure FTP-like file sharing runnning on a single TCP port. Its Java nature gives Java programmers access to remote files as remote `InputStream` and `OutputStream`, with the added value of optionally **compressing data exchange** to ease up network usage.
