Squirrelmail is available at https://www.cs.ucc.ie/squirrelmail. Log in using your Unix username and password.
Squirrelmail can be used from any platform, from work or home. It is IMAP (server) based with ssl encryption.
The Computer Centre (CC) currently filters all incoming mail, from outside UCC, for spam. If a message is found to be spam it is marked as such by inserting the text '**SPAM?**" at the start of the subject line.
If you want to have these messages automatically moved out of your Inbox, please follow the procedure below.
In your home directory there is a file called .procmailrc. You need to add the text below to this file. It is important that you add it exactly as shown.
# rule to catch CCs 'Subject: **SPAM**'
:0:
* ^Subject: [*][*]SPAM[?][*][*]
spam
Save the file and exit.
Also, in your home directory there should be a file called .forward. If it doesn't already exist, you should create it by typing "vi .forward". This brings you straight into the file for editing. You need to add the line below to this file.
"| exec /usr/bin/procmail"
Monitor the 'spam' email folder in your home directory to ensure that spam is being caught. It is important to check the spam folder occasionally as no automatic filter is perfect and there is a slight risk that a valid email message may be flagged as spam.
After monitoring the spam folder for a period you may be satisfied that you are not getting 'false positives'. At this stage, you can configure your email to dump the messages flagged "spam" instead of saving them to your spam folder.
To do this, you simply edit the .procmailrc file in your home directory. The new text should be "/dev/null" instead of "spam", i.e., replace the text your added in the first step with:
# rule to catch CCs 'Subject: **SPAM**'
:0:
* ^Subject: [*][*]SPAM[?][*][*]
/dev/null
If you have difficulty with this procedure, please contact help@cs.ucc.ie.
Your public_html folder is located in your home directory. To allow your documents to be read on the Internet, you must give access to others to read your files within this directory. For example:
rwxr--r-- index.html means that index.html is readable by "group" and "others"
rwx------ index.html means that index.html is readable only by the owner (you) and nobody else.
To change these permissions, you should ssh to cosmos and log on with your Unix username and password. Then cd to your home directory/public_html.
To give access permissions on files do the following:
chmod o+r index.html
OR
chmod 744 index.html
Both commands give others read permission on the file. The only difference is the format of the command, the second version is numeric format.
To give access permissions on a complete directory do the following:
chmod -R o+rx directory-name (give others read and execute permissions)
OR
chmod -R 755 directory_name (give others read and execute permissions)
If this does not work, check the permissions on your public_html directory. It should have read and execute permissions for others, if you want your index.html to be read automatically. If the permissions are incorrect, you need to change them as follows:
chmod 755 public_html
OR
chmod o+rx public_html
If there is still an problem, do the following:
cd (this brings you to your home directory)
cd .. (this brings you up one level)
ls -ld username
Your username directory should appear as:
drwx--x--x username-dir
If it does not, then your public_html directory will not be accessible to others. To rectify this problem, do the following:
chmod g+x o+x username-directory (gives execute permissions to others)
OR
chmod 711 username-directory
After applying these changes, if there is still a problem, please contact the CS Helpdesk. Email help@cs.ucc.ie stating your username, the problem and how you have tried to fix the problem.
**N.B**. Be careful with these permissions because you may cause security problems for yourself and others by giving global write access to your files.
More information on the chmod command can be found in:
http://unixhelp.ed.ac.uk/CGI/man-cgi?chmod
Information on other Unix commands is available at http://unixhelp.ed.ac.uk/
To remedy this problem, go to the Tools menu on your browser.
Select Internet Options and click on the Advanced tab.

.htaccess for Restricting to UCC IP Addresses
This FAQ is based on http://www.uwo.ca/its/doc/manuals/network-policy/node48.html#uwo-only.
To do this restriction, login to student.cs.ucc.ie and change your directory to the one that you want to restrict, for example
cd public_html
and then create a file with the following contents called
.htaccess
AuthUserFile /dev/null
AuthGroupFile /dev/null
AuthName ExampleAllowFromUWO
AuthType Basic
order deny,allow
deny from all
allow from 143.239
When you log in to Squirrelmail (www.cs.ucc.ie/squirrelmail), the graph on the left-hand side indicates how much space you have remaining in your home directory.
If the bar graph is over 90%, then you need to clear some data out of your home directory because this may impact your logging on to your PC and receiving mail.If you find Squirrelmail is slow to open and is slow to use, your mailbox probably needs to be reduced in size. The larger the mailbox, the longer it will take to open. You should ensure that all unnecessary/old mail is deleted on a regular basis. This will maintain Squirrelmail at a reasonable speed and also ensure that you are able to access new mail reliably.
If you are using pop, insert "pop.student.cs.ucc.ie" as your incoming server.
If you are using imap, insert "imap.student.cs.ucc.ie" as your incoming server.
For outgoing email, insert "smtp.student.cs.ucc.ie" as your outgoing server.
Please note that, for security reasons, outgoing server access is only operational from within college.
Open Firefox. Click the Tools Menu and select Options.
When the Options Panel opens, select General in the left-hand pane.
Near the bottom right of the General tab, click Connection Settings.
In Connection Settings, select Manual Proxy Configuration.
Check the box for "Use the same proxy for all protocols".
In the first line (HTTP Proxy) enter:
csproxy.ucc.ie
and in the port box enter:
80
This should automatically fill down to all options except SOCKS.
Click OK, and OK again to exit the Options Panel. Firefox should now work properly.
If you receive the error "Firefox is already running”, it is likely that Firefox is already running but not responding.
To open a new window, you must first close the existing Firefox process or restart your system.
You then need to find your Firefox profile at
~/.mozilla/firefox/[Profile name]/
Inside your .mozilla directory tree, there will be a lock file and a .parentlock file. You must delete both of these files to allow Firefox to run correctly.
