Hi,

which is (wget ftp://ftp.ensembl.org/pub/release-97/fasta/macaca_mulatta/dna/Macaca_mulatta.Mmul_8.0.1.dna.toplevel.fa.gz) I keep getting this error message Error in server response, closing control connection. Retrying. what is the problem? and how to fix it?

Thank you!

Ensembl FTP site was not working yesterday (and perhaps until some point today). It is working now so unless it is a firewall issue at your local institution @Matthias' command should work now.

Yes, it is working now

It's a problem with your or your institution's firewall. When you use the FTP protocol, wget will by default use active FTP and open a second port for the actual data transfer (usually using ports 20 and 21).

Either add the --passive-ftp flag to your command or just use http:// instead of ftp:// for downloading:

wget http://ftp.ensembl.org/pub/release-97/fasta/macaca_mulatta/dna/Macaca_mulatta.Mmul_8.0.1.dna_sm.toplevel.fa.gz
