I happened to use netstat program this morning. And what I couldn't understand were its results. The snapshot of the output is given below:

enter image description here

Can somebody explain to me the last entry in the results, where I've pointed at with arrows?

  1. I don't understand why canonical servers are connected with my computer even if I am not currently using anything that I would expect such a connection to exist.
  2. I don't see the PID/Program name of the Program which has made this connection. I would at-least expect a PID.

If my guess is correct (again, it's a guess, I don't delve deeply into that stuff), kudan is the distro repo. In that case, the connection might originate from the kernel itself. Since the kernel is not a process, there is no PID for it. - I'll leave the actual answer to someone who can confirm just what kudan is and where the connection originates. –  FEichinger Jun 25 '13 at 7:11
@FEichinger Yes, it seems to be a repository, and you're `logic' behind it seems reasonable, too. But again, what's the need of keeping a connection ESTABLISHED with such a server? And as per my understanding, a package manager is supposed to check if there're any updates, and stuff. Why would kernel need to connect to one of Canonical's servers? –  Rohit Jun 26 '13 at 9:00
