I've seen this problem before.  See

    
http://my.unidata.ucar.edu/cgi-bin/getfile?file=/content/support/help/MailArchives/ldm/msg03539.html

When checking the see if a pormapper daemon is running on the host,
the LDM should get an immediate response from the system rather than
have to wait three minutes.  It's highly likely that the
operating-system is discarding the connection request from the LDM to
the portmapper -- resulting in the time-out.

The file

    /etc/sys/config/iptables

contains the firewall rules that would cause this behavior.

The command

    iptables -L

will list the active firewall rules.  You can send the output to us, if
you wish, and we'll tell you what's wrong.
