Hi David, I tried logging in to your machine as 'ldm' using the password that you provided, and four times in a row I got a permission denied message. The fifth time, the SSH attempt seemed to hang for awhile (more than a minute, but I am not sure exactly how long), and then I got a 'Connection closed by' message. Subsequent SSH attempts resulted in: % ssh address@hidden ssh: connect to host twister.esci.millersville.edu port 22: Connection refused % ssh address@hidden ssh: connect to host twister.esci.millersville.edu port 22: Connection refused % ssh address@hidden ssh: connect to host twister.esci.millersville.edu port 22: Connection refused The change in messages suggests to me that there is an adaptive firewall rule that kicked in to block SSH connections from the machine I was coming from: abbott.unidata.ucar.edu (128.117.156.43) Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
