[SOLVED] No browsing flush DNS?
location: linuxquestions.com - date: November 15, 2011
Today, I load up Ubuntu as normal, but although my web browser will display my router's "admin page" (like it normally would) where I can see total amount downloaded etc, it refuses to browse to any other page on the internet. Evolution does not want to get my emails either. However, Transmission is okay downloading and uploading files/torrents. Router seems logged onto internet okay, so clearly I'm connected to something.
Neither Firefox nor Chrome will bring up any web content.
However, my system is dual-boot so on loading into Windows XP to see what happens, browsing is normal, no problems. In fact I am typing this message from Windows - no choice!
I remember something about a "DNS cache" being corrupted as being the reason for browsing not being possible sometimes; however one website says "Ubuntu doesn't cache DNS records by default so unless you've installed a dns cache there isn't anything to clear".
So, given my inability to surf in Ubuntu,
Display and Flush DNS cache

I have a computer assignment and I need the right command in linux. I need to display recent DNS records and clear them whenever I want. In windows "ipconfig /displaydns" and "ipconfig /flushdns" commands are used respectively. Are there any commands in linux which are equivalent to these ones? or in Linux isn't there such an option? Can "ifconfig" solve this problem? If yes what should be the exact options and command line?

How to ssh as root to a workstation and then run commands as another user.

Senario is we have a system where root has authorised keys set up so that it can do a passwordless ssh to $WORKSTATION. I then need to run a script on $WORKSTATION as user "bob" and NOT as user "root". I do not want to set up user "bob" to be allowed passwordless ssh so any ideas how I can do this?
I have tried variations of (as user "root"):
ssh $WORKSTATION "su - bob; ./my_script"
Just hangs unfortunately.

Howto flush dns cache
location: linuxquestions.com - date: May 9, 2010
I have a website that has been migrated to a new server. After a few days I'm still pointing at the old server and the hosting company have recommended that I flush my dns cache. A quick google for this in linux seemed to recommend restarting the nscd daemon but nscd -g tells me it's not running anyway. I connect to Virginmedia via wired ethernet to a Belkin N1 router so is there a way I can do this I wonder, either via Virginmedia or Slackware?
