SP20 bulk setup mini-HOWTO
While setting up my SP20 mini-farm, I tried to figure a process to speed up the config steps usually required to perform over the Web-UI. The following might be useful for you if you need to configure a batch of SP20 devices with the same configuration.

Please ignore if this has been posted already.


Step 1: FW upgrade
If your units are freshly delivered, upgrade all to latest (mine was 2.6.1)

Step 2: configure your reference unit
a) If you need non-standard cgminer configuration (e.g. API access from your monitoring server), ssh into unit and modify /etc/cgminer.conf.template to your needs.
b) configure the reference unit; this scheme covers: root password, UI password, pool settings, HW settings
c) start cgminer and ensure the unit is mining according to the desired configuration

Step 3: grab reference config files
a) on your (Linux) PC, create a fresh directory and cd into it
b) scp from your reference unit the following files

• /etc/cgminer.conf
• /etc/cgminer.conf.template
• /etc/mg_custom_mode_sp20
• /etc/shadow
• /etc/ui.pwd

Step 4: bulk clone configs
a) scp all files to your remaining units (root/root)

Step 5: start the farm
a) open each unit in Web-UI (use the UI password set in step 2)
b) start cgminer


The process improvement is marginal for up to 5 units, but worth if you deal with 10+. It is also less error-prone and can serve as template for automated processing.


Happy mining!
