Inital Access

Danger

Make sure you are connected to the EduRoam network! Virtual machines are only accessible via Eduroam

You have been given pieces of papers containing the following information:

ok: [localhost] => (item=virtual-machine-workshop-04) => {
    "msg": [
        "Instructions: https://bip-ws-docs.cloud.ut.ee",
        "Hostname: virtual-machine-workshop-0x.cloud.ut.ee",
        "Address: 172.17.255.258",
        "Password: lively-xxxxx-pineapp"
    ]
}

Note

PS! This was just a sample, use the information provided to you on the pieces of paper.

We are going to use this information to grant you command-line access to the virtual machines that have been set up for you in University of Tartu's High Performance Computing Center's cloud environment.

To access the virtual machines, we are going to use a command-line utility called ssh which is available in linux, windows and macos operating systems.

Test the connectivity to the virtual machine

Let's first establish the connection to the virtual machine. Use the ping tool to see if the machine is reachable from your machine.

A successful ping output looks something like this:

Example

daisy@fowl % ping -c4 172.17.89.152
PING 172.17.89.152 (172.17.89.152): 56 data bytes
64 bytes from 172.17.89.152: icmp_seq=0 ttl=62 time=18.497 ms
64 bytes from 172.17.89.152: icmp_seq=1 ttl=62 time=19.609 ms
64 bytes from 172.17.89.152: icmp_seq=2 ttl=62 time=18.578 ms
64 bytes from 172.17.89.152: icmp_seq=3 ttl=62 time=16.762 ms

--- 172.17.89.152 ping statistics ---
4 packets transmitted, 4 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 16.762/18.361/19.609/1.022 ms

Important

4 packets transmitted, 4 packets received, 0.0% packet loss - this means that your computer can access the right network and is able to reach the machine.

If you ping output looks correct move on to the next part. If not, please contact a supervisor.

Connecting to the virtual machine

Like mentioned earlier, you are going to use a command-line utility called ssh to access the virtual machine.
