I try to use ncbi remote database to make a blast search, but it failed. There is a warning message I don't understand. How can I use this option?
The warning message is
Please make sure your firewall does not block ports 4444-4544 bound for NCBI(126.96.36.199/188.8.131.52)
my command line is
$ blastn -db nr -query sequence.fasta -remote -out result.bls
