expect execute linux command
location: linuxquestions.com - date: April 24, 2012
Hi
I wrote a script in "expect" hoping it can login to remote host and execute a simple "pwd" command. But it seems its not working. Can anyone point me in the right direction. The program logs in but does not execute a command or so I dont see it on my output screen.
-----------------------
#!/usr/bin/expect
set ip {x.x.x.x}
set cmd {pwd}
spawn ssh -q "$ip";
expect -re ".*\#";
send "$cmd\r";
-----------------------

How to use Linux DNS Server for windows machines
location: ubuntuforums.com - date: October 16, 2011
Hi guys,
My situation is like this:
I'm using Windows XP
I installed VMBox and a Virtual Machine which is an Ubuntu Server
On Ubuntu Server, I installed Apache and Bind9. I also changed /etc/resolv.conf to use the DNS installed.
Testing:
On Ubuntu Server, I can ping 192.168.56.102(ubuntu server)
On my windows XP, I can open web browser at http://192.168.56.102
But I can't use http://example.com (which was configured in Bind 9 to point to 192.168.56.102)
Can someone help me please?
Kind Regards,
DNS poissoning MyFamiliy.com (I tought no one can do this to linux)
location: ubuntuforums.com - date: July 25, 2009
Hi early this morning, while i was trying to open www.kubuntu.com, something strange.. my browser didn't view my desire page, instead of viewing a pages titled MyFamily.com
I try ubuntuforums.org (it works) , but www.coldplay.com also drives to MyFamily.com
some sites work, but many failed.
googling around, i found that it's DNS poisoning problem. a solution is doing cache flush..
unfortunately, i dont know how to cache flush in linux. I've tried to flush my iptables by typing
Code:
sudo iptables --flush
but the problem persist.
This is really annoying.. why this MyFamily.com do this?
any suggestions?

Howto flush dns cache
location: linuxquestions.com - date: May 9, 2010
Hi,
Slackware64 13.0
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?
