RE: Firewall logging port 6346

If you are using a dynamic ip then the obvious answer is the correct one. Most likely the person on that IP before you was sitting on the Gnutella network for some time. I know of no specific malware that uses this port (I don't know everything though!!!!) I would be unconcerned. It does not mean the network is broken there in Italy, it just means that the client on that end is attempting to resume a download they were transferring before from that client (instead of searching again to find different sources).

Subject: Firewall logging port 6346

My firewall has logged 131.114.2.90 trying to connect to my port 6346, this has been happening for quite some time now, about once a minute.

I know that this is the standard port for Gnutella (it also says gnutella-svc), but I would like to know if this is just a server trying to connect to the wrong machine (I'm using a modem to connect to the internet, dynamic IP, maybe someone was communicating with 131.114.2.90 before I connected using this IP?), or could this be some malware?

I traced the 131.114.2.90 machine back to ser-fib.unipi.it (131.114.191.50), but traceroute couldn't get any further. Could this mean that the network is slow / broken down there in Italy (I suppose it's Italy).

Best regards,

Jos Kirps
