It's about a month that I see some unknown connections in nethogs and I tried to understand what program is responsible for them but I failed.

  1. I'm not sure but it seems that my Internet connection becomes laggy or lost every time this connections appear

  2. They only appear for a short time and as I notice them they are gone.

  3. I'm from Iran. Every time these IPs show up, I can only open websites that are inside Iran (I mean the servers are in Iran) and I can't open any other website! That's really strange.

Are these normal connections? If true, what are those for? If false what should I do?

192.168.1.2:53483-91.98.103.126:80

i was trying some of security tips.... i activated UFW and tried some tips from here: https://www.thefanclub.co.za/how-to/how-secure-ubuntu-1204-lts-server-part-1-basics
(activated IP spoofing protection).

Today the Internet problem happened again. I lost my access to non-Iranian servers/sites but the IPs didn't appeared in the NetHogs and the connection problem lasted for several minutes instead of seconds.

I will update this post with more details(if any) hope you can understand the exact situation.

    First of all, please don't use screenshots unless absolutely necessary. They are not searchable and neither can the text be copied. `nethogs` groups bandwidth by process, so what process is running. Maximize the window to see more of the PROGRAM column. Also a quick check of the IP addresses using a WhoIs query shows that the first is going to Iran, while the second is going to Google. – garethTheRed Jun 16 '16 at 13:53
  • sorry for screen shot and thank you for the comment. i did maximized the window but the only thing that appeared was the IP. i noticed that the DEV for other connections is wlan0 but the DEV column for this connection is empty – vAB Jun 16 '16 at 20:21
