I am looking for a tool which will monitor my internet speeds periodically. I have seen things such as Netflow Analyzer but it looks like those focus on local bandwidth. I just want to see what my internet performance looks like over time.
Something with a web UI would be great because I would like to install this on my server. Anyone aware of such a tool?
Thanks,
I know this is asked often but nothing seems to work for me. Every time I try to update I get the following:
sudo apt-get update
Get:1 http://archive.ubuntu.com precise Release.gpg
Get:2 http://ppa.launchpad.net precise Release.gpg
Get:3 http://archive.ubuntu.com precise Release
Get:4 http://ppa.launchpad.net precise Release.gpg
Get:5 http://ppa.launchpad.net precise Release
Ign http://archive.ubuntu.com precise Release
E: GPG error: http://archive.ubuntu.com precise Release: The following signatures were invalid: NODATA 1 NODATA 2
The only way I can successfully execute
sudo apt-get update
is by removing ALL software sources (which is pointless).
Regardless of whatever software source I use (official ubuntu or some other PPA) I get the same errors.
So far I have tried:
Nothing seems to work. It seems that all my key data is missing and I can't figure out how to get it back.
Any help would be very appreciated !
In order for me to boot into 12.04, I have to add the parameter acpi=off in grub. Any other options as specified here do not allow me to boot into Ubuntu.
My question is simple, what does setting the parameter acpi=off actually do?
And more importantly does repeatedly booting with acpi=off damage or harm the computer in anyway?
