= Location of your files =

All the files you want to provide via the web browser must reside in a directory named "www" in your homefolder. Within that folder you can organise your data in sub directories. For more information about accessing your files is available [https://docs.ulyssis.org/Accessing_your_files here].

= Accessing your website =

Your webspace is accessible on following url's (with username your username):

* http://username.ulyssis.be
* http://username.studentenweb.org

If you have a domainname like yourname.be, you can link it with our webserver. For more information on this subject, see the [https://docs.ulyssis.org/Adding_domain_names domainnames documentation].

= Troubleshooting =

I keep getting an "HTTP Error 403: permission denied" when accessing my website.

Try changing the permissions of your www-directory. Log in to a ULYSSIS shell machine and type:

<code>chmod o+x ~
chmod o+rx ~/www</code>

You may want to receive e-mail from ulyssis on another email provider. It is very easy to set this up.

# Go to ucc.ulyssis.org and log in with your username and password.
# On the right side, click on '''Mail'''.
# Under '''Address forward''' you can change the forward address of your ULYSSIS mail by clicking on '''edit'''.
# Choose '''forward''' and enter the email address you want to forward your ULYSSIS mail to and save the changes.
# If you forward it to your Gmail account, it is recommended to [[Add an alias in Gmail]] so you can send mails from your ULYSSIS accout using Gmail.

Transferring files over SFTP

2014-08-26T13:11:16Z

W29: /* Transferring your files over SFTP */

ULYSSIS doesn't support ftp, because it is insecure. However, we support sftp (ftp over ssh).
This works similar as ssh.

On the server, your files are located in <code>/home/group/username/</code>. For a normal user with username <code>username/</code> this will be <code>/home/user/username/</code>, for an organisation with username <code>organisation/</code> this will be <code>/home/org/organisation/</code> etc.

==Non-graphical methods==

The most common way to transfer files is with a terminal by using the <code>scp</code> command. 
Copying file to host: 
<code>scp SourceFile user@host:directory/TargetFile</code> 
Copying file from host: 
<code>scp user@host:directory/SourceFile TargetFile
scp -r user@host:directory/SourceFolder TargetFolder</code>

You don't need to use the full path to your file. You may you the relative path, starting from your home directory. For example: 
<code>scp index.html user@ssh1.ulyssis.org:www/index.html</code>

==Graphical methods==

The graphical methods are explained in [[Accessing your files]].

Accessing your files

2014-08-26T13:11:00Z

W29: /* Accessing your files */

Next to running commands, you can also use the shell servers to access your files. There are several methods to do this, some graphical, some not. The former definitely are the easiest option to go for.

On the server, your files are located in <code>/home/group/username/</code>. For a normal user with username <code>username/</code> this will be <code>/home/user/username/</code>, for an organisation with username <code>organisation/</code> this will be <code>/home/org/organisation/</code> etc.

==Graphical methods==

===Linux===

Linux normally gives you the option to connect to a server graphically. On Ubuntu, in the "Places" menu, choose "Connect to server." using the following options:
<ul>
<li>Service type: SSH</li>
<li>Server: ssh1.ulyssis.org or ssh2.ulyssis.org</li>
<li>Port: you can leave this blank</li>
<li>Folder: your home folder as described above (this is optional, this will save you clicking to your home folder)</li>
</ul>

This will open up a file browser connected to the remote server. Here, you can create new files, delete files, upload files (by copying or dragging them in the file browser), download files (by copying or dragging them from the file browser), change file rights etc.

===Windows===

Windows doesn't support native remote file browsers, so you will have to download a program first. A good option is [https://filezilla-project.org/ FileZilla], which is completely free. Download it, install it and run it. The parameters:
<ul>
<li>Dropdown menu: SFTP (SSH File Transfer Protocol)</li>
<li>Server: ssh1.ulyssis.org or ssh2.ulyssis.org</li>
<li>Port: you can leave the default value</li>
<li>Username: your username</li>
<li>Password: your password</li>
</ul>

===Mac===

Download the free and open source program [http://cyberduck.ch/ Cyberduck]

Follow the installations instructions and afterwards open Cyberduck in your Applications folder.
Click on 'Open Connection' in the left top corner.

<ul>
<li>Dropdown menu: SFTP (SSH File Transfer Protocol)</li>
<li>Server: ssh1.ulyssis.org or ssh2.ulyssis.org</li>
<li>Port: you can leave the default value</li>
<li>Username: your username</li>
<li>Password: your password</li>
</ul>

Click on 'Connect' and you're done.
By dragging and dropping you can manipulate files from and to your Mac.

==Non-graphical methods==

You can also use a terminal (on Linux) or Putty (on Windows) to access your files. Connect to the server as described above, and use commands as <code>cd</code>, <code>ls</code>, <code>mkdir</code>, <code>rm</code>, <code>nano</code> or <code>chmod</code> to manage your files.
You can also use <code>scp</code> (secure copy) to copy files from and to the servers (don't use <code>ssh</code> first). For example, to copy a file called <code>file.txt</code> to your home dir on the server, use (with <code>username</code> your username and <code>/home/user/username</code> your home dir as described above):

<code>scp file.txt username@ssh1.ulyssis.org:/home/user/username
</code>

Fetch your KU Leuven email into another email address

2014-05-13T15:52:05Z

W29: Created page with "You can use our shell-servers to forward mails from your KULeuven mailbox to an email provider of your choice (e.g. GMail). DOING THIS IS ENTIRELY ON YOUR OWN RISK. ..."

You can use our shell-servers to forward mails from your KULeuven mailbox to an email provider of your choice (e.g. GMail).
DOING THIS IS ENTIRELY ON YOUR OWN RISK. ULYSSIS CANNOT BE HELD RESPONSIBLE FOR LOST/DELAY MAILS. BY HAVING OUR SERVERS FORWARD YOUR KULEUVEN MAIL, YOU TAKE FULL RESPONSIBILITY.
This tutorial is based on http://ronin.ulyssis.be/files/kulmail_gmail2.txt
We wrote a script that configures everything automatically. To use it, log in on one of our shell servers and execute the following commands:
<ul>
<li>wget ftp://ftp.ulyssis.org/kulforward/kulforwardsetup.sh</li>
<li>chmod u+x kulforwardsetup.sh</li>
<li>./kulforwardsetup.sh</li>
<li>Follow the instructions on the screen.</li>
</ul>
Alternatively, you can configure everything yourself. Below we briefly explain how to do this.
<ul>
<li>Create a directory to save the SSL certificates: mkdir .certs</li>
<li>Put the necessary certificates in the .certs directory: cd .certs wget ftp://ftp.ulyssis.org/kulforward/imapkul.pem wget ftp://ftp.ulyssis.org/kulforward/usertrust.pem cp /etc/ssl/certs/AddTrust_External_Root.pem . cd
</li>
<li>Rehash them: c_rehash ~/.certs/</li>
<li>Create the fetchmail configuration file with your favourite text editor and enter the confiration details: 
$login = your KULeuven login (e.g. s0123456) 
$pass = your KULeuven password 
$mail = the email address to forward your KULeuven mail to (TRIPLECHECK IT!!) 
keep = "" (delete forwarded mails from your KULeuven mailbox) or "keep" (keep forwarded emails) 
set daemon 600 # Check every 10 minutes 
poll imaps.student.kuleuven.be port 993 protocol imap username "$login" password "$pass" smtpname "$mail" ssl sslcertck $keep sslcertpath .certs/</li>
<li>Add it to your crontab 
crontab -e 
@reboot fetchmail
</li>
<li>Because of our setup fetchmail cannot be started automatically when the shell server is restarted. But you if you add it to your crontab, you'll get email that it failed. You can then manually login on our shell servers to start fetchmail again.</li>
<li>Start fetchmail: 
fetchmail</li>
</ul>
