I could recommend the Lustre Filesystem. It's GPL licensed and used by Cray for their XC line of supercomputers. I have written parallel applications that heavily leveraged this particular FS across about 100 nodes; though I don't know how to set it up or configure it. Using it is just as you would expect with everything appearing just as files and ...

Yup - you want ntop - https://www.ntop.org/ Install it on a machine that traffic passes through (I use a Pi as a router for part of my network) and you can access the GUI for reports, etc. via browser.

Off the top of my head, any one of these sounds like it might meet your requirements: GlusterFS: GNU GPL3 MongoDB: Server Side Public License (SSPL) InterPlanetary File System: MIT license, Apache license 2.0 The GlusterFS I usually use is set up so that each file in the special "DATA" folder is stored twice somewhere on a 3-server cluster, each one ...

I have experience with CMDBuild and PHPIpam for all kinds of network and asset management, but I'm sure you can find numerous alternatives if you browse a little bit on https://alternativeto.net/software/phpipam/ and https://alternativeto.net/software/cmdbuild . I hope this helps. If you're looking for a general documentation web solution, I can recommend ...

Unfortunately, the most of free tools are not properly developed and supported anymore. Sometimes, it worth spending some funds (not much) on properly working and simple paid software. 10-Strike Network Inventory Explorer does everything you need. It scans computers using WMI, and printers (and toner level) via SNMP.

Wireshark will already capture packet timestamps. I believe it uses PCAP internally for the low-level work. See https://github.com/the-tcpdump-group/libpcap

Not sure if it meets all your requirements, but you could take a look at Matrix. It is an open messaging protocol based on a federated model similar to email, in which messages are replicated across multiple servers. There are public servers or you can run your own. End-to-end encryption is possible. It does require an account, but you don't have to ...

You can try dmails, based on blockstack blockchain: Send Emails, Store files and Pay, with the World's FIRST server-less Email service. No more spam. Based on Blockchain Tech. You may want to watch a 2-minutes video about it. It's pretty much an e-mail-like app, but it doesn't work with regular e-mails. You exchange messages through blockstack ids (...

200 at a time is basically impossible due to bandwidth restrictions. You can't even use 90% of all bandwidth or you will cripple your users ability to use the network. However, doing them in small groups should be ok. Many scripting languages can do something like this. https://powershellexplained.com/2017-04-22-Powershell-installing-remote-software/ ...

The server can use UDP multicast to publish the characters, that way it does not really need to care about what clients exactly are listening. The clients just need to register to the multicast group and listen what the server is sending. In addition, for the feature of pausing, create a (unicast) UDP socket the server is listening on and that the clients ...

Nmap can also find devices outside your current subnet, if your building has multiple subnets (ex. 192.168.1.43 and 192.168.2.32) and the tomcat server is on the other one you're not conneted to, we can eventually look further... Open a terminal, check your current gateway and subnet mask, and afterwards run a TCP stealth scan on the gateway. ip route ...

The fact you have an application running in the background defies the purpose of "users using the information" you mention My suggestion is to not hurt your brain and resources and use a Google Drive document (possibly a spreadsheet) which is shared in read-only. Provided communication runs unhindered, it will always sync with what is edited on the master. ...
