DNS names for lab work

20.08.2019 - 12:42

Some labs/classroom work require valid DNS names, for example, for certificates to be valid. Internally, all LabraNet users are allowed to use a domain .zz (for example, A1234.zz if your student-id is A1234). Under this domain, one can add as many hosts and DNS records as necessary.

The personal domains under .zz top level domain are resolvable only locally from classrooms and personal workstations in LabraNet. The domain/subdomains are also not DNSSEC signed.

To handle your records, log in to zz.labranet.jamk.fi using your LabraNet credentials.


Password Resets

04.10.2018 - 09:29

If you have forgotten your LabraNet password or otherwise want to change it remotely, you can use the LabraNet Self-service portal when the following applies:

  • Your account is not disabled / locked
  • You have access to your JAMK email account

The Self-service portal can be found at:

student.labranet.jamk.fi/passwd/

By filling in your LabraNet username and reCAPTCHA, you can generate a password reset link which will be sent to your JAMK email account.

Email form

Opening the link from your email account will lead to a form with which the password change can be completed. Read the password requirements and fill in your new password twice and complete the reCAPTCHA. Click Submit to complete the password change.

Reset form

Note!

  • If you have forgotten your JAMK account password, you can reset it via Vetuma
  • The email link is only valid for 10 minutes

If the password reset fails or you have trouble with the service otherwise, please contact LabraNet helpdesk.


LabraNet GitLab

02.10.2018 - 14:22

GitLab is a web-based Git repository manager with additional features, such as wiki, issue-tracking and CI/CD pipelines. LabraNet Gitlab can be used by students to host their study related software development projects.

Logging into LabraNet GitLab

Users can use their LabraNet credentials to sign into the GitLab. If you don’t have a LabraNet account, see FAQ for more information. On the front page the LabraNet sign in-option has to be selected.

Backing up projects

Individual projects are not backed up, so users are responsible to keep backup copies of their projects. Repository contents can be backed up cloning  the repository. The entire project, including wiki, issues and settings can also be exported.


VPN to LabraNet

11.09.2018 - 12:58

You can access your home folder and other resources from your home network with VPN. Instructions for connecting to the LabraNet VPN and mounting your home folder can be found in the LabraNet Remote Access Guide

If you encounter any problems with VPN connection here are few remedies to known problems:
– DNS problems are often solved by flushing the DNS cache (in windows the command is “ipconfig /flushdns”, in linux you need to restart nscd daemon with command “/etc/init.d/nscd restart”)
– Connectivity problems are caused by not receiving proper routes from VPN connection, DHCP clearance is often needed to get VPN routes. In windows commands are: “ipconfig /release” and after that “ipconfig /renew”. In linux “dhclient -r” will renew DHCP bindings.
– Check whether the VPN tunnel is in full or split mode (See Advanced Routing in the Guide). Sometimes full tunnel mode works better
– In newer Mac OS X, check the Service order in the Network settings page, and the scutil –dns command output. Wrong service order will make the system use your default DNS servers, and the system cannot resolve LabraNet names.
– If the Windows 10 app freezes and doesn’t show connection options you can complete or close the connection using the following command line commands:
– To make the connection: rasdial.exe “connection name” (add username and password if you haven’t saved them in connection options: rasdial.exe “connection name” “username” “password”)
– To close the connection: rasdial.exe “connection name” /disconnect


Virtualized environments

11.09.2018 - 12:58

Some courses and theses are done in virtualized environments, such as the VMware vSphere Hypervisor (ESXi). SpiderNet Center is a clustered environment for handling lab virtual machines. SpiderNet_Virtual_Machines includes some common help and guidelines for using such environments and working with them.

If you bring us virtual machines for use in labs or the vCloud Director environment, the images should be VMware vSphere 5.0 compatible (VM version 8) and in OVF/OVA format as plain VMX/VMDK images can be troublesome. If using software other than VMware to create the images, please remove USB/Audio devices and use SCSI disks instead of SATA/IDE. More information about format conversion in the guide above.
