Re: [Dorset] dorset Digest, Vol 360, Issue 5
I would appreciate any advise and help on networking. (they say a little knowledge is a dangerous thing). I have been running etherape and it shows that my Linux system is sending out a lot of packets to IP addresses. I do do not have anything running (that I know of) and disconnecting from the Internet shows that these connections are still shown, but they are removed after time-outs occur. Doing a 'netstat -a' shows a lot of connected states. (even tho' I have unplugged the router connection to the Internet). (I have run 'transmission' for a torrent download some time back which may be the cause of the connections, but that is not running). It would appear that somewhere, something is trying to re-establish connections to the systems out on the Internet. I would expect to have no connections, especially when I have nothing communicating to the Internet. (maybe things like the update manager).
