Host key verification failure: Trying to launch ssh

[Gupta]

Hi,

I am trying to launch a simple ssh command via jenkins from a Windows machine to a Linux machine but getting the below error:

c:\jenkins\workspace\x86_Linux_SmoketestB>ssh ro...@192.168.x.x "ls -l /usr/local/SWAT" 
Host key verification failed.

c:\jenkins\workspace\x86_Linux_SmoketestB>exit 255

This command works fine manually though. Any suggestions on how to make it work?

Execute ssh without a parameter and then accept the host key.

Another option would be to use 'ssh -s StrictHostKeyChecking=no
ro...@192.168.x.x "ls -l /usr/local/SWAT"' but I don't think that's what
you want to do.
