Provisioning process is happening as follows:
- Flush the DHCP lease database (Danger: should only be done once throughout the event)
- flush-dhcp.sh - Flushes the databae and gives out information
- Parse the DHCP lease file for MAC addresses
- parse-dhcp.sh - Output is a CSV file with MAC per line called ioi2019.csv
- Assign IPs to these MAC addresses
- append-ip.sh - Variables are configured inside the script. Input is the output of parse-dhcp.sh. Output is a CSV file with MAC,IP per line called IP_ioi2019.csv
- MAC,IP CSV file will be provisioned to DHCP
- provision-csv.sh - Variables are configured inside the script. Input is the output of append-ip.sh. Output is a DHCP conf file with MAC,IP reservations (contestant-static.conf))that should be copied to /etc/dhcp/. Then run:
sudo systemctl restart isc-dhcp-server
- Get seat id by web service and add it as a new column: MAC, IP, seat
sudo cp IP_ioi2019.csv ../../../SeatLocator/data.csvneeds to be run to copy MAC,IP pair to seat web service. Everytime an update occurs to a location, DATA_Export.csv is the one which needs to be exported out of the web service. Relocation scripts will need this file.
To create an IOI 2019 contestant image, follow the instructions below:
- download and install Ubuntu 18.04 (Bionic Beaver) into your computer machine
- create an user under the name of contestant
- run either sudo ./isolate-install-configure.sh or sudo bash isolate-install-configure.sh command
Everytime a contestant is moved to a new location, seat web service is needed to be run. However, in case, a new laptop is given to the contestant, then relocate.sh is needed to be run (you would need ioidhcp user's password):
./relocate.sh seat reserve_laptop_number, where seat is the current location of the contestant and reserve_laptop_number is the spare laptop (to be given) number in laptops.csv file.
The script backs up the current DHCP reservations file (contestant-static.conf) and creates a new one. Then, after manually verifying it, an admin should move it to /etc/dhcp/ folder and restart the DHCP server with sudo systemctl restart isc-dhcp-server
