) imply that you are executing commands on remote equipment, or within another program.Log in to your virtual machine as the sysadm user.
Install the necessary packages for RT. You should have mysql-server already, but we do the install just in case. This won't cause problems.
Copy the "sudo apt-get install" line below, minus the "$" and paste this in to your terminal session on your virtual machine.
$ sudo apt-get install rt4-apache2 rt4-clients rt4-db-mysql request-tracker4 libapache2-mod-fastcgi libfcgi-perl mutt
Respond "Yes" when prompted if you wish to install the packages.
You will now be presented with several windows. Read the follwing instructions to see how to respond:
Name for this Request Tracker (RT) instance:
Remove what is shown and replace with "netmgmt", then select <Ok>
and press ENTER
to continue.
Handle RT_SiteConfig.pm permissions?
<Yes>
and press ENTER to continue.Configure database for request-tracker4 with dbconfig-common?
<Yes>
and press ENTER to continue.Password of the database's administrative user:
Enter the MySQL root
or admin
password. This was set earlier in the workshop (probably when you installed Cacti). If you do not remember what this is, or if it's not written at the front of the classroom, ask an instructor for help.
MySQL application password for request-tracker4:
You may enter any password you wish. This will be used by Request Tracker to connect to MySQL. You generally do not need to remember this password. Pick something that cannot be guessed easily (i.e., don't use rt
, requesttracker
, 1234
, etc...).
Password confirmation:
Initial root password for RT system:
Now you will see quite a bit of information go across your screen as the Request Tracker installation process completes - It's a big package.
At this point you have installed Request Tracker version 4. In order to access RT via the Apache web server you need to make a few small changes.
First let's update the Requestion Tracker (RT) configuration to improve the "From:" field format that will be used when RT sends out emails to users. In addition we will restrict attachment sizes and we will add our RT server to a whitelist to avoid cross site forgery error messages for legitimate RT usage.
Request Tracker maintains configuration files in the directory:
/etc/request-tracker4/RT_SiteConfig.d
We will go to this directory, create a new configuration file called 90-local and regenerate the RT RT_SiteConfig.pm file using the update-rt-siteconfig command:
$ cd /etc/request-tracker4/RT_SiteConfig.d
$ sudo touch 90-local
$ sudo edit 90-local
Add the following two lines to the file 90-local:
Set($MaxAttachmentSize , 10000000);
Set(@ReferrerWhitelist, qw(x.x.x.x:80 SERVNAME:80));
In the ReferrerWhitelist entry x.x.x.x. is the IP address of your PC and SERVNAME is the name of your PC. That is, if you are on pc1.ws.nsrc.org you would enter:
Set(@ReferrerWhitelist, qw(10.10.1.1:80 pc1.ws.nsrc.org:80));
Be sure to use the correct IP address and name for your PC, then save the file and execute the command:
$ sudo update-rt-siteconfig
Now we have one more change to the Apache web server configuration to make:
$ cd /etc/apache2/conf-available
$ sudo ln -s /etc/request-tracker4/apache2-modperl2.conf rt4.conf
$ sudo a2enconf rt4
$ sudo service apache2 restart
The last step could take up to 30 seconds, so be patient! RT should now be up and running!
Log in to RT as the root User
If you go to http://pcN.ws.nsrc.org/rt/ you will see the RT login screen:
Enter the following information to log in as root
on RT:
Username: root
Password: [SELECTED AT INSTALL]
RT Configuration: Create a User
Now that you are logged in we will create a new user for the rest of these exercises.
On the top of the screen choose Tools => Configuration => Users and then click on the Create item in the menu.
You will now be presented with the following dialogue. Fill in the fields, and make sure the checkbox Let this user be granted rights
is checked. Set your email to sysadm@
pcX
.ws.nsrc.org
(X = your PC)
Use the same password for sysadm
as you are using in class. Be sure you check Let this user be granted rights
. Once done, scroll down the page and click on the Create button (bottom right). You should see this:
RT Configuration: Create a Group
netmgmt
, and add a description, then click on CreateAdd members
field (right), type in the name of the user you created in step 3. This is the sysadm
user. Then click on Modify Members (bottom right):RT Configuration: Create a New Queue
Queue Name: net
Description: Network Problems
Subject Tag: RT: NET
Reply Address: net@pcX.ws.nsrc.org
Comment Address: net-comment@pcX.ws.nsrc.org
Note: Remember to replace pcX with the correct number of your machine
You should see this:
RT Configuration: Give Rights to our Group on the Queue
From the top menu, select Tools => Configuration => Queue => Select
You should see:
net
(click on it) then choose Group Rights
(top right)The following page should look like this:
Note the three categories: General rights, Rights for Staff, Rights for Administrators
Here, we want to give Everyone (including people who are not yet known to RT) some privileges, but only the minimum required. These are found under General Rights, and are the following:
(CreateTicket)
(ReplyToTicket)
(SeeQueue)
(ShowTicket)
So start by selecting these 4 privileges by checking the 4 boxes in your browser.
Notice that Everyone on the left is already highlighted.
Now, click Save Changes (bottom right) to make sure the changes are applied.
Staying on the same page, we're going to now give the netmgmt Group all rights...
To do this, first type in the name of the group in the ADD GROUP field in the lower left:
Now check ALL the boxes in General Rights, Rights for Staff, Rights for Administrators.
Once this is done, press the Save Changes button on the bottom right of the page. You should see:
This is after having selected items. Remember to press Modify Group Rights after selecting the new rights. Once you press the Modify Group Rights button you will see a bunch of this:
RT Configuration: Log in as sysadm
Log out of RT (top menu, select the item Logged in as root => Logout)
Now log back in as the sysadm
user you have created:
You should see the following:
At this point RT has been properly configured for initial operation. Now we must configure email properly to talk with our new net
queue in RT.
RT Configuration: Email
RT will work with the MTA (Mail Transfer Agent) of your choice. In our case we are using Postfix configured to run as an MTA for an <<Internet Site>> - that is, to deliver email locally and remotely using SMTP.
Edit the file /etc/aliases
$ sudo editor /etc/aliases
Add the following two lines at the end of the file (copy and paste!):
net-comment: "|/usr/bin/rt-mailgate --queue net --action comment --url http://localhost/rt/"
net: "|/usr/bin/rt-mailgate --queue net --action correspond --url http://localhost/rt/"
Save the file and exit. Some editors might cause the above-lines to become multiple lines. Be sure that you only have two new lines in your /etc/aliases
file after copying and pasting in the text above.
Now run the command:
$ sudo newaliases
RT Configuration: Create an Email and Tickets
Let's create an email and send it to the RT net
queue. Do this as the sysadm
user (not as root
!):
If you are currently root
:
# su - sysadm
$ echo "Problem with my router" | mail -s "Router problem" net@pcX.ws.nsrc.org
Remember to replace pcX with the correct name of your server.
Now check that you have received email:
$ mutt
You should see an email from Request Tracker acknowledging that your ticket has been created.
The mail should say something similar to this:
Date: Fri, 9 Nov 2012 00:29:27 +0000
From: Network Problems via RT <net@pcX.ws.nsrc.org>
To: sysadm@pcX.ws.nsrc.org
Subject: [Request Tracker: NET #1] AutoReply: Router problem
Greetings,
This message has been automatically generated in response to the
creation of a trouble ticket regarding:
"Router problem",
a summary of which appears below.
There is no need to reply to this message right now. Your ticket has been
assigned an ID of [Request Tracker: NET #1].
Please include the string:
[Request Tracker: NET #1]
in the subject line of all future correspondence about this issue. To do so,
you may reply to this message.
Thank you,
net@pcX.ws.nsrc.org
If, for some reason, you do not see mail try taking these steps, and then send the mail again:
$ sudo touch /var/mail/sysadm
$ sudo chown sysadm:mail /var/mail/sysadm
RT Configuration: View, Reply, Resolve, Reopen Tickets in Request Tracker
Go back to your web browser where you are logged in to RT as the sysadm user and click on the Home menu item (top left).
You should then be presented with an updated view with the current ticket:
Now, click on the ticket subject.
You will see many pieces of information about the ticket. Scroll to the bottom of the page.
Here you can Reply to the ticket:
Go ahead and type in a reply, set the Status of the ticket to Resolved (upper-right drop-down menu), and then click on Update Ticket (bottom-right):
You should see this:
The ticket is currently Resolved but you can reopen the ticket via the RT web interface at any time, or if the original ticket creator (sysadm
in this case) replies to the resolution email RT sent, then the ticket will be reopened.
View the history at the bottom of the page to see that the ticket is currently resolved:
If you went back to your terminal session as the sysadm user and typed:
$ mutt
and responded to the email generated from Request Tracker, then your ticket status will change. You can see this by reloading the RT web page for the ticket and viewing the history at the bottom of the page:

You can experiment a bit. Now, this is not a very realistic setup, since you are communication with yourself! But in fact, other users in the classroom can send you email:
sudo apt-get install postfix
then accept the defaults)echo "Where is my cat ?" | mail -s "Missing cat" net@pcX.ws.nsrc.org
net
queue on your pc "pcX" - verify that you do receive the tickets!We are still missing an important feature: it's not practical to have to log into RT to check if tickets have arrived. It would be much more convenient if we received an email every time a problem request had been submitted, no?
Now to receive an email every time a request is submitted we're going to modify the Queue settings for net
:
From the Queue page, select the net
queue by clicking on its name, and you select the Watchers menu option at the top:
You should now see this:
Under New watchers, enter the group name netmgmt in the field: <
And click on Go!
RT will search for all groups matching netmgmt. Of course there is only one right now, which we created earlier. RT finds it and displays the following:
Notice how we select AdminCc
from the pull down memu Groups next to netmgmt. Do this and click on Save Changes at the bottom right.
The result should look like this:
What does it mean ? Well, ask another user to send you a mail, like before, but this time you should receive a mail from RT with the ticket notification - run mutt
as sysadm
.
A bit later we will extend the use of RT by integrating it with other Network Monitoring software using the rt-mailgate facility that we have already configured in the /etc/aliases
file.
Finding a ticket once it's closed.
After a ticket has been resolved or closed may notice that it disappears from your Queue. Actually finding a closed ticket requires a few steps. First, click on Tickets => New Search on the top menu in RT:
and you will see a screen like this:
If you are going to search for items in a queue and there are already items in the <<Current search>> box, then you should delete the items from the <<Current search>> box first. Next in the <<Add Criteria>> box in the <<Queue>>" choice select the <<net>> queue from the drop-down menu (see below):
Click on <<Add these terms>> or <<Add these terms and Search>> - If you just do <<Add these terms>> then go to the bottom of the page and click on <<Update format and Search>> - RT will keep the search terms until you delete them at a later time.
And the results of your search will look something like this and you will be able to view tickets that have been closed, resolved, etc. Clearly there will be more tickets in the results over time:
