[opensuse] Versiera has established connection?
I did use the command SS and stumbled on Leap and TW upon "versiera". tcp ESTAB 0 0 127.0.0.1:51678 127.0.0.1:versiera I have done a research and it is a package of netcraft communications. https://www.netcraftcommunications.com/docs/Versiera-UserGuide.pdf As I have a TrueNas server running on the network, it could be that this is the source of "versiera" but I am not sure. Actually the finding was a surprise to me. How to I read the SS output to understand if a source is on my machine or on a distant machine? In this case I see. the socket tcp has established a connection on local host, via the port 51678 but then I do not understand what 127.0.0.1:versiera means? Is this local or remote?

"ss -ltn" will show your both local and peer addresses - if the latter are not local to the machine, they are on another/remote/distant machine.

Both are local, 127.0.0.1 is localhost. "versiera" is the name of the port - grep versiera /etc/services -- Per Jessen, Zürich (7.8°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland.

Long line. I can't use long lines in new Thunderbird. Switch to alpine. This is what you got, with labels: Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port tcp ESTAB 0 0 127.0.0.1:51678 127.0.0.1:versiera So, "versiera" is the peer port, the peer at the other side. It is a local connection, from port: 51678 to port: versiera. Huh? Look: Telcontar:~ # grep versiera /etc/services versiera 9050/tcp # Versiera Agent Listener [Frank_Pikelner] Telcontar:~ # So what you got was this: Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port tcp ESTAB 0 0 127.0.0.1:51678 127.0.0.1:9050 Same thing. versiera=9050, that's all. It doesn't need at all that you have something actually related to versiera in your machine. The network outside is not involved at all, because the address is 127.0.0.1. The ports are not hard tied to be some fixed service, they can be anything else, randomly assigned. - -- Cheers, Carlos E. R.
