I am slightly worried about getting into trouble...

I have installed Xarp and when I opened it, it started listing IPs. I am on a public network, so would it get flagged on the administrator's side??

  • you are worried about getting into trouble because you have monitored traffic on that public network ? – cyzczy Mar 11 '17 at 17:18
  • I assume you mean xarp? – schroeder Mar 11 '17 at 17:22
  • Without inspecting the program myself, I suspect that it just listens to the network. There would be nothing to detect. – schroeder Mar 11 '17 at 17:24

As far as the network is concerned, no, you do not need to be concerned. XArp listens to ARP broadcast packets which are sent to your machine, it does not generate traffic (emphasis mine):

XArp will inspect every ARP packet and report attacks against remote machines. Some inspection modules can only work for the local machine (e.g. StaticPreserve), but most modules will not need any local information. They monitor each ARP packet and can thus detect ARP attacks against other machines. Be sure to deploy XArp on a machine that sees all network traffic from the whole subnet. XArp can only monitor and inspect packets that it can see.

Depending on your environment, it is possible that your Administrator does see programs; for example, many anti-virus packages will alert upon security tools. However, I would think XArp is unlikely to trigger alerts, it's a purely defensive tool with no offensive capabilities.
