The cluster utilities are script allowing to work in parallel with a
number of remote hosts, using utilities such as Parallel SSH (pssh) or
fping. They all take as first and mandatory argument a host list name
“NAME”; the list will be searched according to the following pattern:
``` $HOME/.config/cluster/NAME.lst
For example, one can call the cluster-ping.sh script typing:
``` cluster-ping my_hosts
to use the hosts' file $HOME/.config/cluster/my_hosts.lst
The format of such a .lst file is one line per host name or IP address,
for example:
```
192.168.42.1
192.168.42.3
priam
```
The scripts provided are detailed in the sequel.
= cluster-ping.sh =
Test the connectivity with the hosts of the list by sending them a ICMP
echo packet.
Dependency: fping
= cluster-ssh.sh =
Open a GNU Screen tab with an interactive SSH session for each host of
the hosts' list. Must be run inside of an existing Screen.
Dependencies: screen, ssh
= cluster-run.sh =
Run the same command on every host of the hosts' list.
Dependency: parallel-ssh (pssh)
= cluster-deploy.sh =
Deploy one or more files in parallel on every host of the hosts' list.
Dependency: parallel-scp (pscp)
