If you are using departmental Webmail for email messaging you should empty your account regularly, so you do not exceed your quota. Select one or more messages from your Inbox and select the option ¨Delete¨. With this option the messages are not deleted. To remove them completely, and not occupy space you should select the ¨Purge Deleted¨.

Why and where to create .forward files

  • Run SSH on any UNIX machine on the CS Department
  • Create (if not exist) to your home directory a .forward file.
cs4034:/home/students/cs/pgrad/csp6ma1>vi .forward

This file should contain the email address where your email wants to be sent. For example, This email address is being protected from spambots. You need JavaScript enabled to view it.

(If this file exist on your home directory, all emails that are sent to you, this will be sent automatically to This email address is being protected from spambots. You need JavaScript enabled to view it.)

Check the permissions on your .forward file. They should be:

-rw-r--r--

This means that .forward is writable only from you, but it is also readable from user/group/other.
In case you have to change the permissions run this command:

cs4034:/home/students/cs/pgrad/csp6ma1>chmod 644 .forward

For more complex send and filtering, the program procmail can be used.

There are many sources with information that you can advice to find the computer services that are available to the Department. All included as options on ITS website. First, you have to visit User Guides. The guides contain a collection of user guides instructions and transactions information on various issues framed by general descriptions very detailed instructions on specific issues. If you don't know how to start or you are new at the Department then you have to start with the new users guide. If you work on one of this lab, please read the instructions about labs. Read the FAQ!! Here you can find short replies to most usual questions and indicators for more information. Visit the Announcement area on Helpdesk where you can find the most update information on changes that have taken place or underway. Use the search tool on ITS website on Helpdesk to find the issue that you are interested in. There, you can find information or answers on problems that have already solved.

Return back any equipment that you have borrowed. If you have signed for any equipment, then it is assigned to you, therefore just say that it is officially returned back. University policy is that student account should remain open for further two years after finishing the degree. Although, if you want to close your account, then you have to arrange your data to be stored in a way that you can transfer them and then to clean data areas. Give special attention to data that can be stored in your personal system. If you want to keep your account open, then notify IT support team which is your plan such as your account to remain open.

Be careful that this process is valid for academic, management staff and students. Use the following process to create your personal website that can be accessed using URL style <server>/~<username>

For example:

http://www.cs.ucy.ac.cy/~ank

1. Create a sub directory in your home directory (on UNIX system) and name it: public_html. The command for this is: mkdir ~/public_html . Next you have to set the permissions of this new directory to 755 (rwxr-xr-x , using command chmod 755 ~/public_html). All sub-directories that you will create later should have the same permissions.

2. Create your webpages in this new directory. In order someone to be able to access your page, knowing only your login name is essentially to name your home page as index.html. On this way, your webpage can be accessed from the URL: http://www.cs.ucy.ac.cy/~username

3. Be sure that files are public readable. (UNIX permission form should be rwxr--r—- for all files. MS-Windows permission should provide access form everybody). Don´t put other permissions than those in your job. On your home directory you can set permissions at least rwx..S..x. Be sure that you know what you are doing, if you don´t follow those permissions. If you give more loose permissions you will enable other users to see and maybe to destroy your job (not only your webpage).

Be careful: Any file that you put on public_html will be visible through public_http so don´t put there, any files that you don´t want other users to see them.

More detailed descriptions on available servers, methods and functions for the webpage development is available to Web Development

You can run Tex/Latex on aias.cs.ucy.ac.cy. The following directories should be included on your own variable PATH$ on your profile /usr/local/tex/bin/rs6000/usr: /local/tex/bin: /local/TeX/bin

More information on DreamSpark, who can be a member and how, can be found here.

VPN is a software that can provide a secure connection to your computer on Department network. It is used for a remote connection (from house) and it can be used to access computers on the department, like Unix lab. Also you need it to be able to see your files on your home directory from your house.

The VMAP program enables the members of the Department to obtain VMware software for free. Software virtualization lets you run simultaneously more than one operating systems on your computer. To access the VMAP program follow the instructions given on DreamSpark program.

To change password, you have to connect in any linux machine of the department and run the command: passwd. Next, you have to follow the instructions. List with all available machines can be found Here and Here. Your new password will be valid immediately. Please, be careful that with unix password change, your password at Windows environment will automatically change too. Password change on linux has nothing to do with password of bannerWeb, Blackboard or other non Computer Science systems

In order to change your password on Windows, you have to connect on a Windows computer connected to CS-UCY-AC-CY domain. After connecting, press CTRL+ALT+DEL and select the button "Change Password", then follow the instructions. Please, be careful that with password change on Windows, your password for Linux environment (email, Moodle, etc) will automatically change too.

In order to change your password via website go to departmental website, and choose the link Change password/Αλλαγή κωδικού. If you need more help on this you can take a look on user guide.

First create a file called .vacation.msg on your home directory and write your message in the file. An example of what you can put in the file is shown here.

Example:

Dear '$FROM'

I will be away from my office until February 30th, 2007.
I will read your message regarding '$SUBJECT' when I return on February 31st.

Warning: Dont forget "." at the beginning of the name of the file.

• Then create a file called .forward

The file should have the following line:

\username, "| /usr/bin/vacation -t# username"

Where username is your login name and # is the number of days before sending the vacation mesage to the same recipient again.

  • Enjoy your vacation!
  • Once you return back delete the .forward file or move it to a different name to stop sending vacation messages.

When you exceed the quota, you will notice that the Inbox is empty and you can’t receive new emails. You should post on the helpdesk a request to increase your quota temporarily. You should monitor the Helpdesk because you have 48 hours after the IT Support Team response to your request, to enter your E-mail account and delete the messages or move them to local directories (local folders).

Quota is the limit that you have for saving your data on Department systems. Users quotas are as follows:

E-mail

Year

Quota

First 400 MB
Second 400 MB
Third 600 MB
Fourth + 1 GB
Master - PhD 4 GB
Research 4 GB
Alumni 2.2 GB

 

Home Directories:

This is for U: drive that you can see on Windows, which is the same as /home/students/cs/<path>/<username> of Unix

Year

Quota

First 960 MB
Second 960 MB
Third 1.6 GB
Fourth + 2 GB
Master - PhD 2.4 GB
Research 20 GB
Alumni 1 GB
Students of other departments 500 MB

 

Windows Profile:

All students have a limit on their Windows Profile space, 80ΜΒ total. Analytically, there is a quota limit on: Desktop and My Documents on 50MB and other 30MB for the rest space that Windows use. (Application Data etc)

Printing Quota:

On the beginning of each academic year, account of each student is credited with €120,00 for printing notes and projects. Then if you need further printing quotas, you can credit your account by contact department reception. The same applies for students of other departments who attend a course on the department, for whom, their account is credited with €4,00.

Information on this you can find in the New User Guide, at section "ενεργοποίηση λογαριασμών".

I can solve the problem in three ways:

1.    If you are in a unix lab, from the login screen of a machine, press Ctrl+Alt+F1. You transferred to “text console” and login with username and password. Run the command du -hs *. This command gives the size for each directory and each file, where located in the central file. So you can see the size of each directory. Another situation is if the directory of Mozilla .mozilla is very big (especially if used regularly Mozilla). I can see the size of the directory with the command du -hs *. In this case, I must run the command rm –rf .mozilla. Run the exit command and transferred to the graphical mode. Then try login to the system.

2.    If you are on Windows lab: Go to U:\ drive, choose the option from the Organize → Folder and search options → View → Show hidden files, folders, and drives. You can choose .mozilla and delete it or you can see the size of each directory separately. Another option is to move them to windows Documents or in a usb drive.

3.    If you are at home, connect to a unix machine with ssh. Follow the steps as in the case 1, to see the size of directories/files and delete accordingly.

First of all don't shut down the PC. On this way, any changes that you have done on your profile, as well as new files that you create will not be saved!

1st Step: When you run some application, many large files are created, which is better to delete them from your profile.

You can find them on C:\Documents and Settings\<username>\Application Data (Windows XP) or on C:\Users\<username>\AppData (Windows 7)

Application Data is hidden and in order to see it, from any folder go to:  Tools Organize → Folder and search options → View → Show hidden files, folders, and drives

If you use specific settings for some of the applications that are appeared on Application Data, it is better to delete a specific application folder. For example if you have bookmarks in Firefox, site on Macromedia, saved sessions on XWin etc.

2nd Step: Delete from your profile all .eclipse, .java, .borland etc, if you don´t use those applications anymore.

3rd Step: If you have finished Oracle course, delete Oracle Jar Cache folder .

4th Step: If you cannot solve the problem, use Helpdesk (tool for electronic help) to send the problem to ITS.

First of all, you have to connect with VPN. Next, you have to use FTP (for example: FileZilla) or SCP program (for example: WinSCP) and connect to the port 22 to any Linux machine using your username and password.

The most of Unix systems are automatically synchronized through Network Time Protocol (NTP service from external constant clocks). You can easily synchronize your PC clock going to NTP service website. Be careful that this synchronization will need to be repeated every time identified that the time in your machine is not real.

To give a user access to a database, a request form must be filled out "Request form to create website for studies/conferences" and applied on Technical Support Team (forma). The request should declared:

1. The type of database (MySQL, Oracle, or MS_SQL)

2. The name of the database

3. The desired username to access the database

4. Start and end of program/conference

In cases where the request was filed by a student or researcher, the request for the creation of the database must be supported by an academic who is responsible for this project/site/course.

Instructions to connect on an SQL Server can be found on guides and more specific on the guide Database Development (in Greek)

In addition, more details can be found on this link.

To connect to SQL Server from a remote computer, you have to follow the steps:

Go to Control Panel/User Account

Image

Select User Account and then from “pick an account to change” select the account that you work on it.

Image

From Related Task select Managed my network passwords

Image

Then you have to press Add button and to complete the form as followed

Image

At the end you have to press Ok
