I created new rules for port 1935 i/o using Plesk/Modules/Firewall but this doesn't work. Nmap scanning tells me this :
1935/tcp filtered rtmp

On one of my servers when I type netstat -n I get a huge output, something like 400 entries for httpd. The bandwidth on the server isn't high, so I'm confused as to what's causing it. I'm suspecting an attack, but not sure.

I ran a clean install to Ubuntu 12.04 and so far everything has been working well. I especially commend the Ubuntu team for this release.
I only noticed that the size of repository update is now about ~13MB. Normally, it is about this size for the first time you run apt-get update after a clean install…

I have a fresh install of Ubuntu 11.10 from the iso 'ubuntu-11.10-desktop-amd64.iso'. I installed this in VMWare Fusion 4.1.1 running on OSX 10.7.3.

I realize there are dozens of "apt-get update: failure to fetch" questions (I read through all I could find), but my present circumstance is unique to 12.04 and it affects all sources; not just launchpad. Additionally, I've tried several different servers in Europe and the U.S. as well as the "main…
