This exercise should be done by each person in your group as you will create separate userids on the RT instance your shared srv1 server.
Log in to RT as the root User on your shared srv1 server.
If you go to http://srv1.campusY.ws.nsrc.org/rt/ you will see the RT login screen:

RT Configuration: Create your User
Now that you are logged in we will create a new user for the rest of these exercises. The user you will create is "sysadm-hostX, where "X" is the number of your host.
On the top of the screen choose Admin => Users => Create and then click on the Create item in the menu.
Create User
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@hostX.CampusY.ws.nsrc.org - Replace X with your host number and "Y" with your campus number.
User creation form
Use the same password for sysadm-hostX 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:

Group rights
The following page should look like this:
Group rights overview
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.
Modify group rights
Now, click Save Changes (bottom right) to make sure the changes are applied.
Saved rights
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:
Add rights to group
Now check ALL the boxes in General Rights, Rights for Staff, Rights for Administrators.
All rights selected
Once this is done, press the Save Changes button on the bottom right of the page. You should see:

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.
(Only one person does this exercise)
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.
First, we need to verify that the file /etc/mailname has the correct entry.
$ sudo editor /etc/mailnameBe sure that the only entry in this file is:
srv1.campusY.ws.nsrc.orgWhere "Y" is your campus number. Once you have updated the file or verified it is correct save your changes (if any) and exit from the file.
Next we will edit the file /etc/aliases
$ sudo editor /etc/aliasesAdd 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 newaliasesRT Configuration: Create an Email and Tickets
(Only one person does this)
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@srv1.campusY.ws.nsrc.orgRemember to replace the "Y" in "campusY" with your campus number.
If you get an error about mail not being installed, then do:
$ sudo apt install mailutilsAnd run the "echo" command above again.
Now check that you have received email:
$ muttYou should see an email from Request Tracker acknowledging that your ticket has been created.
Select that email and press
The mail should say something similar to this:
Date: Fri, 24 Feb 2017 00:21:19 +0000
From: Network Problems via RT <net@srv1.campusY.ws.nsrc.org>
To: sysadm@srv1.campusY.ws.nsrc.org

Problem with my routerIf, 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/sysadmOnce you read the mail press the "q" key twice to exit from mutt.
(Select one member of your group to do this. Everyone can see the ticket, but only one person should edit it at one time).
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-hostX user and click on the Home menu item (top left).
You should then be presented with an updated view with the current ticket:
Main page - ticket overview
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:
Display ticket
Go ahead and type in a reply and then click on Update Ticket (bottom-right):
Replying to ticket
You should see this:
Reply sent
The ticket is still open. Let's resolve it:
View history
Click on "Update Ticket" at the bottom of the screen to finish resolving the ticket.
View history
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:
View history
If you went back to your terminal session as the sysadm user and typed:
$ muttand 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:
Using Mutt to Reply to an Email

You now have a functioning RT instance with email integration!
Try having users from the other hosts in your campus send email to your RT ticket queue on the srv1 shared server.
sudo apt-get install postfix then accept the defaults and be sure to set /etc/mailname to the correct value.)echo "Where is my cat ?" | mail -s "Missing cat" net@srv1.campusY.ws.nsrc.orgnet queue on your server "srv1.campusY" - verify that you do receive the tickets by checking in RT on your shared srv1.campusY.ws.nsrc.org instance!(Only one person should do this)
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?
Logout as sysadm
Log in as root
Now to receive an email every time a request is submitted we're going to modify the Queue settings for net:
Select queue
From the Queue page, select the net queue by clicking on its name, and you select the Watchers menu option at the top:
Queue watchers
You should now see this:
Modify queue watchers
Under New watchers, enter the group name netmgmt in the field:
New watchers
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:
Matched groups
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:
Watchers modified
What does it mean ? Well, ask another user to send a mail to net@srv1.campusY.ws.nsrc.org to create a ticket, like before, but this time everyone who is a member of the net queue should receive a mail from RT with the ticket notification.
You can test this by issuing this command as the sysadm user on srv1.campusY.ws.nsrc.org:
$ echo "Yet more problems with my router" | mail -s "More Router Problems" net@srv1.campusY.ws.nsrc.orgRemember to change "Y" to your campus number.
Now log in to the other machines in your group and see if each sysadm user has received an email with this subject and text.
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.
(Anyone in the group can do this)
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.
You would need to close one of the tickets in your net queue before this search will provide you with any results. Right now you should have two open tickets. In your RT screen click on "Home" (upper-right of the screen) and you should see something like this:
Current Open Tickets
You should select one, or both, of these tickets and "resolve" them before continuing with this exercise (see previous exercises for resolving a ticket).
Now, click on Tickets => New Search on the top menu in RT:
Search tickets
and you will see a screen like this:
Ticket search form
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):
Adding search terms
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.
Execute search
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:
