Dear Sir/Madam,

Hello!

I am trying to use the PORT (Parallel Offline Radiative Transfer model) aiming to get the radiative forcing, following the instructions from Example: Using PORT to study flux differences due to 2 x CO2

At the first step, "Sample the base run", when running the ./case.build script, I got the error message like this:

Code: 
Checking server ftp://ftp.cgd.ucar.edu/cesm/inputdata with protocol wget
Setting resource.RLIMIT_STACK to -1 from (-1, -1)
Using protocol wget with user anonymous and passwd user@example.edu
Could not connect to repo 'ftp://ftp.cgd.ucar.edu/cesm/inputdata'
This is most likely either a proxy, or network issue .
Checking server ftp.cgd.ucar.edu/cesm/inputdata with protocol ftp

    resp = self.getresp()
  File "/home/anaconda3/lib/python3.7/ftplib.py", line 246, in getresp
    raise error_perm(resp)
ftplib.error_perm: 550 Failed to change directory.

It looks like the error occurs in ./check_input_data.py at CESM-release-cesm2.1.3/cime/scripts/base_run_case. I tried to run check_input_data.py alone and got the same error message.

Sincerely,
Liren

Our ftp server is currently down for maintenance. This has exposed a problem in the check_input_data script not handling the error properly.
