I am using the NCBI script script thus: --verbose --force nt.
I get the following message:
Net::FTP>>> Net::FTP(2.77)
Net::FTP>>>   Exporter(5.58)
Net::FTP>>>   Net::Cmd(2.29)

The script has worked in the past. Is anyone having similar problems? Any suggested trouble-shooting steps would be appreciated.

You need to enable Passive Transfers

Net::FTP class has a method that you can use:

pasv ()

    Tell the server to go into passive mode.

In case someone finds this thread while searching for this issue, you can ask update_blastdb to use passive mode.

$ update_blastdb --passive --decompress nt
