Script to run Klocwork from Machine 1 to machine 2

I use Ubuntu 10.04 in 2 virtual machines. In one machine I have installed Hudson and another machine is to run klocwork. Scenario is when I trigger a build in Hudson, the script has to run successful and call the Klocwork in VM2. In the build script I have given the following command to call Klocwork in machine 2. Below is the script I use to call machine 2 from machine 1.

if [ $Klocwork = "true" ]; 
then 
   echo "Starting Klocwork Report ..." sshpass -p 'password' ssh IP-address "sudo chmod 755 /localpath/build_script_kw.sh;
   /local path/build_script_kw.sh $SVNID $Version" fi 
echo "Build Successfully."

when I run the script, I get Host key verification failed error. Please provide me a solution for this issue.

Please let me know, if there is any modification to be done in the script.

Thanks,

Host key verification is probably just telling you that the hostname you're hitting showed a different key in the past. SSH manually and the error should probably pop up, then just delete the offending line from known_hosts in your ssh folder (Normally ~/.ssh/).
