My friend is using 12.10 and noticed how the command "colord-sane" shows up on lsof every time he plugs in or unplugs a usb-stick. I tried the same thing on 12.04 (what I use) and colord-sane does not show up.
What is colord-sane? Why is it showing up on 12.10? If it doesn't need internet access why is it even showing up at all on the lsof watch? How would my friend go about stopping it from trying to get on internet if it was something he wanted to stop?
When using the various CLI network monitors like LSOF, Netstat, ifTop. I'd like to see what applications are doing DNS lookups (using port 53 over UDP). How do I configure so that these connections are shown in the Terminal? I'd like to see what IP Address is being connected to and what applications are requesting the DNS lookup.
I'm interested in any way to learn this information.
I want to redirect some sites to localhost. I can use hosts file which resides in directory C:\WINDOWS\system32\drivers\etc in windows.
Which is equivalent of this file in Ubuntu?
I have a G73JW laptop using Ubuntu 12.04. It has an Atheros AR9285 card.
While wifi seems to work fine most of the time, about every hour or two it will loose the connection to the internet. The connection will appear to be connected still to the wireless router, but internet access is gone.
Disconnecting and reconnecting to the access point solves the problem, as does disabling and reenabling the adapter via the hardware keyboard shortcut.
How might this be solved so the connection is stable and doesn't drop?
EDIT: It looks like the network dropping isn't related to DNS as it fails either way:
codyloco@CodyLoco-Ubuntu:~$ dig askubuntu.com @8.8.8.8
; <<>> DiG 9.8.1-P1 <<>> askubuntu.com @8.8.8.8
;; global options: +cmd
;; connection timed out; no servers could be reached
codyloco@CodyLoco-Ubuntu:~$ dig askubuntu.com
; <<>> DiG 9.8.1-P1 <<>> askubuntu.com
;; global options: +cmd
;; connection timed out; no servers could be reached
Again cycling (disabling / enabling) the adapter corrects the issue.
I have a slow Internet connection and every time I add a new ppa to install software I need to run apt-get update.
This takes about 10 minutes or so, I was wondering if there was a way to initiate a partial update for the newly added ppa's.
