Problem executing task

[Karunakar Chatla]

Hi,

I am relatively new to FreeBSD and ANT.
I wanted to fire a command on FreeBSD box from a windows box. I am using 
<sshexec> task to accomplish my task. 
I have downloaded jsch-0.1.21.jar and copied it to lib folder of ANT. Following 
is by build file.

<project name="DARTmail" >
 <target name="Build" >
  <sshexec host="172.18.225.17"
    port="23"
    username="user"
    password="password"
    command="ls"
    output="${output.folder.path}\ssh.log"
    failonerror="true"/>
 </target>
</project>

I am getting following error on running above script : Is there any settings to 
be done to get connection to FreeBSD box?
I mean, should we change any settings on FreeBSD box to allow the connection?

This is very much urgent for me now. Can anybody help me out?
