Since the introduction of a firewall at IAAT, incoming FTP connections to IAAT machines are only allowed to astro.uni-tuebingen.de. Unfortunately, the introduction of the firewall has made the process of FTPing to astro.uni-tuebingen.de slightly more complicated. The cause for this is that the firewall does not allow standard old FTP clients to connect through it. Symptoms of this are that the login-process works o.k., but that a time-out is received at the first dir or get command. The technical explanation for this behaviour can be found elsewhere.
If you need to connect to astro.uni-tuebingen.de from the outside, you will need to use an FTP client which allows the use of the so-called ``passive mode'' (or PASV-mode). Clients allowing the use of this mode are most web-browsers (e.g., netscape), web offline readers (e.g., wget), and modern FTP programs (e.g., ncftp, mirror or FTP Explorer for Windows NT machines). Follow the links to these programs for explanations on how to setup the FTP clients.
Finally for the small print: Anonymous FTP is a privilege and not a right. Misuse of the account has occured in the past. We are therefore forced to log all transfers from the anonymous account. German law requires us to inform you of this logging. If you feel that your privacy rights are violated by this, do not use the account.
When accessing a non-anonymous ftp-account with netscape or the internet explorer, you need to use the syntax ftp://name:email@example.com in order to enable the authentification at the remote server.
If you want to provide a message that is to be displayed when the subdirectory is first accessed, put the message in the file .message (yes, including the leading dot) in the subdirectory.
Example: To provide data, do the following:
aittyc~> mkdir ~ftp/pub/wilms aittyc~> cp test123 ~ftp/pub/wilms aittyc~> chmod go=r ~ftp/pub/wilms/test123 aittyc~> echo Testdatei fuer x aus y > ~ftp/pub/wilms/.messageTo reiterate, access to the ~ftp hierarcy is available from all Unix machines. Since the files still belong to you, your quota will apply. Furthermore, old files on the anonymous FTP will be removed from time to time, so please clean up after yourself.
