Service Desk Call Handling Procedure

  • RT tickets can be escalated by changing the Queue to backoffice with the Owner set to Nobody and the Status as new. Tell the requestor:
    I am passing this request over to the experts who, I'm sure, will be in contact shortly.

Certificate Requests

We should handle certificate requests and generate the CSR rather than ask users to do it as it is a bit fiddly and they often get the details wrong resulting in too many iterations. Windows is easy if for a single machine but difficult for requests with Subject Alternative Names (SANs) added.

Procedures are documented on the CL WiKi using the email address sys-admin@cl.cam.ac.uk for any correspondence.

Note that the background process here is:

http://www.ucs.cam.ac.uk/tlscerts/

In the 1st instance you will recieve a query such as:

 Hello,
 Please may you generate certificates for these CSRs?
 Thanks!

The request will look something like:

      Happy to get these processed for you but just need to clarify a couple of points.
   1. I need to update which servers you require these for?

   Tomcat
   Microsoft IIS5
   Microsoft IIS6
   Microsoft IIS7
   VPN device
   SSL device
   Web logic
   IBM Websphere
   Lansa
   Other
  2. Can you state which certificate you require please?
  Standard QuoVadis Certificate (OV)
  QuoVadis Wildcard Certificate (recharged at cost)
  QuoVadis Extended Validation (EV) Certificate


Once the requestor replied with the information required then go to here to register your cerficates:

https://tlscerts.uis.cam.ac.uk/

Take the confirmtation:

 And other info:

 Organization: University of Cambridge
 Organizational Unit: Computer Laboratory
 Common Name: husky0.dtg.cl.cam.ac.uk
 Email address: dtg-infra@cl.cam.ac.uk

And paste this onto the ticket to record what has been done.


Then when the Certificate is approved send the user a reply and give them this link for guidance:

Then You can download the certicattes and forward them as attachments in email to the requestor.


Link the tickets send form to the certificate provider as children of the original request.

And after the private key is created:

1. Copy private key file (.pem) to requestors home directory adding the date to avoid filename clashes using:
sudo cp cdn-dtg.pem /homes/ipd21/2015-02-16.cdn-dtg.pem

2. Make sure only that person can read it as it is this file that ensures that the site is what it claims to be using:
sudo chmod 600 /homes/ipd21/2015-02-16.cdn-dtg.pem
then
sudo chown ipd21:ipd21 /homes/ipd21/2015-02-16.cdn-dtg.pem

3. In the RT Ticket tell the person it is there and that we'll pass on the certificate when we have it from the UIS.

4. Pass-on the certificate to the requestor when it arrives from the UIS into RT.

Hints, Tips & Known Issues

Janet Certificate Service: SSL certificate expiry notice for ServerName

Graham Titmus (27/01/15)

You may receive email from JANET warning that a certificate is due to expire shortly. However certificates are often replaced early. Check the certificate using IE to the web-server & click the padlock next to the URL & view certificate to check the expiry date. If it's later than JANET think the ticket can be Resolved with an appropriate comment. If it is due to expire soon follow the escalation route.
