Access¶
In the following we will describe how to take ownership of the Giraf Servers for the Giraf Project. We will also describe how to access the servers once ownership has been transferred and how to pass on the servers to a new semester of Giraf Developers.
Ownership Transfer¶
Once a new semester needs to take ownership of the servers for the Giraf project an email with the new admins student mails must be send to support@its.aau.dk with the Semester Coordinator Ulrik Nyman (ulrik@cs.aau.dk) as CC. Once Ulrik has verified the new admins they will be added to the Giraf Server Admins Active Directory group at ITS.
System¶
Once added to the group each admin can access the servers via SSH with the following command:
1 | |
The servers are on the following IP's:
| Name | Internal IP | External IP |
|---|---|---|
| giraf-master00.srv.aau.dk | 172.19.10.29 | 192.38.56.151 |
| giraf-master01.srv.aau.dk | 172.19.10.30 | 192.38.56.153 |
| giraf-node00.srv.aau.dk | 172.19.10.31 | N/A |
| giraf-node01.srv.aau.dk | 172.19.10.32 | N/A |
| giraf-node02.srv.aau.dk | 172.19.10.33 | N/A |
| giraf-node03.srv.aau.dk | 172.19.10.34 | N/A |
The entire project has two public IPs and with has a DNS A record to srv.giraf.cs.aau.dk.
Power Management¶
If the servers does not power on after a system reboot the power management can be accessed via the vSphere Client on https://esx-vcsa03.srv.aau.dk/ui/.
To see the servers goto Menu -> VMs and Templates
Access Problems¶
The vSphere Client site is only accessible from inside the AAU network and even
is not guaranteed to be accessible by ITS. To be sure the user must connect via
VPN to AAU. On Linux Mint the package network-manager-openconnect-gnome must
be installed to allow for access to the Cisco VPN. Once installed add a new VPN
of type CiscoAnyConnect and specify ssl-vpn1.aau.dk as the gateway. When trying
to connect the network manager will ask for your username and password, once provided
an external passcode must be entered. To get this the user must sign up for MSA
passcode at https://mfa.aau.dk/ just use SMS if nothing else
is preferred.
Pass on the Servers¶
The admins are not removed from the admin list before they leave AAU and their student mail is deleted. Hence the admins are expected to help the new semester doing the project start up and give an short introduction to the work that has been done.
