with something like x.xx be careful in keeping the same amount
of characters and leave the period where it was. (file size can
not be changed). Save the buffer an that's it. Next time you do
a telnet to your ftp port the version name is not going do reveal
version number.

ftp://ftp.astro.su.se this one does not
reveal any info after the 220 line.

Please update your summary to make it clear that we do NOT provide ftp
server software for download. The server software we are running (I won't
tell you what it is ;-)) is available in source code form from other sites
on the Internet, but not from us. There are several open-source ftp server
packages for you to choose from (wu-ftpd, proftpd, publicfile, ...);
pick the one with the most appropriate combination of features,
trustworthiness, and licensing. As soon as you are compiling from source,
you have full control over the identification string returned, unless
the license forbids you to change it.
