Problems to download packages

[Karl Berry]

    I encounter a problem when downloading packages from tug's ftp
    server.  Every time after I successfully downloaded a package, I
    have the impression, that the server blocks me.

tug's ftp configuration has no such rule.

In general, it is better to use (a) any protocol other than ftp (http[s]
or rsync), and (b) any other server than tug.org. FTP on tug.org is
perpetually overloaded, primarily because of stupid web browsers that
like to open as many concurrent ftp connections as they can.

Let me take this opportunity to mention for the archives that nowadays
there are several mirrors of the "historic" TeX archive, which for many
years was available only from tug.org (via ftp and rsync) -- see
