GIS.lab administration

User accounts management

Creating new user

New user accounts can be created by using gislab-adduser command, the command below creates ordinary user lab1 with lab as password.

$ sudo gislab-adduser -g User -l GIS.lab -m lab1@gis.lab -p lab lab1

Note

Superuser accounts can be created by -s flag, such user will be able to perform sudo operations on client machines.

Tip

See User accounts customization section to perform customization when creating or deleting user accounts.

List existing users

With gislab-listusers list of all GIS.lab users is displayed, see example below.

$ sudo gislab-listusers | grep uid:
uid: uid=gislab
uid: uid=lab1

Machines management

Enabling GIS.lab client

By default, no client machines are allowed to boot from GISlab server. To allow client machine, there are similar steps to steps described for virtual mode. Simply run gislab-machines command on GIS.lab server and enable the client.

sudo gislab-machines -a <MAC-address>

Tip

Good way to collect MAC addresses of client machines is to plainly let them try to boot and than run following command to get list of denied MAC addresses on GIS.lab server.

$ sudo grep -e 'DHCPDISCOVER.*no free leases' /var/log/syslog

Network management

GIS.lab network can operate in two modes. GIS.lab is possible to integrate into existing (corporate) local area network (LAN) or to run its own computer network controlled by DHCP server on GIS.lab master machine. By default (since GIS.lab version 0.6) DHCP service is disabled on master. GIS.lab network is managed by gislab-network administration command.

Note

This functionality has been added in GIS.lab version 0.6.

Current status is reported by

$ sudo gislab-network status

[GIS.lab]: Connection forwarding service is disabled and inactive.
[GIS.lab]: DNS service is disabled and inactive.
[GIS.lab]: DHCP service is disabled and inactive.

DHCP and DNS service can be started on master node by

$ sudo gislab-network start

This settings is not persistent, to enable DHCP/DNS service automatically after booting master run:

$ sudo gislab-network enable
