Network stress testing can reveal how spikes in packet levels may impact network device performance. The WAN Killer tool in Engineer’s Toolset serves as a network stress tester by generating and sending packets to provide a realistic idea of how devices would perform in the event of sudden or extreme jumps in traffic. For example, Block downloads from Salesforce for unmanaged devices. Assign a Policy severity and Category. For the Session control type, select Control file download (with inspection). This setting gives you the ability to monitor everything your users do within a Salesforce session and gives you control to block and protect downloads in real time.

R-Studio Emergency is run from a removable media when it is necessary to recover data on a computer, where operating system cannot start up because its system files are corrupted or deleted.
There are two R-Studio Emergency versions: R-Studio Emergency TUI (Text User Interface) and R-Studio Emergency GUI (Graphical User Interface). *
R-Studio Emergency Startup Media Creator is installed under Windows OS and creates R-Studio Emergency (TUI or GUI) startup floppy disks set**, any removable startup media*** or ISO Image for the startup CD/DVD (available for direct download bellow).
Read the help page R-Studio Emergency: Creating Startup Disks for more details.
R-Studio Emergency ISO Images are used to create R-Studio Emergency**** startup CD. To create the startup CD you should use any disk burning utility to burn a CD from the downloaded ISO Image. You may download R-Studio Emergency ISO images for Intel-based Macintosh, Windows, Linux and UNIX computers/servers.

You may read more about emergency file recovery for Windows computers in our article Emergency File Recovery Using R-Studio Emergency.

* Both versions have the same functionality but R-Studio Emergency GUI can not be run on a PC if its graphics card is not supported by the utility.
** The floppy disks set supports a limited number of storage/network devices and is not recommended if you may create a startup CD.
*** A startup USB media or ZIP drive can be created and used if a computer BIOS supports booting from them.
**** R-Studio Emergency is included in R-Studio package but its activation key is generated separately and requires a hardware code obtaining. The activation key can be requested through Client Portal within one year from the date of purchase.
