We can download the latest blast binary package for various Unix and Linux platform from the same directory as for Windows ftp://ftp.ncbi.nlm.nih.gov/blast/executables/LATEST/.
These packages have ".tar.gz" file extension. They are named using blast-#.#.#-CHIPSET-OS.tar.gz convention, where the #.#.# represents the current version number, or the patch release date if bug fixed version was made. The CHIPSET represents the processor. And the OS represents the operating system. We need to select the appropriate archive for a given platform. Refer to Table 1.3 for details.
We can use a browser or an FTP client to download the selected package. Note that NCBI does not support asymmetric protocol and requires that an FTP connection be made in PASSIVE mode. Use an FTP client with such capability such as ncftp to do the downloading. A complete process using ncftp is given in the Figure 2.2.1.
