java.net.UnknownHostException

Hi,

I downloaded the latest J2SSH API and wrote a simple Java application that
connects to two different servers and retrieve files under a given directory
path and ftp the file list.  When I run this utility in one set of servers,
it works fine.  But when I run the same utility in other set of servers, I
am getting the following error

INFO: Loading message authentication methods
java.net.UnknownHostException: rosidentapps2
        at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:177)
        at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:364)
        at java.net.Socket.connect(Socket.java:507)
        at java.net.Socket.connect(Socket.java:457)

        at com.sshtools.j2ssh.SshClient.connect(SshClient.java:774)
        at gov.dhs.visit.om.filediff.FileDiff.main(FileDiff.java:74)

I was able to ping the server in question "rosidentapps2" from the command
line.

Also when I look at the FileDiff.java:74.

I see the following code segment

ssh.connect(properties, new IgnoreHostKeyVerification());

Does that mean this particular server "rosidentapps2" somehow has been setup
differently than the other two servers?  If so, what is different?  What
should I be looking?

Thanks in advance,

Mustafa
