General practice for scripts that update networks
 
Hi there,

So far with this network I am building, I have been using ssh keys for authentication when using a script that communicates with multiple computers. However, I have just been reading quite a few posts saying that it is risky to share private keys with multiple computers. So how are commands usually issued from a server to all other computers on a network for example doing updates?

kind regards

No plans to use software such as Nagios, Zabbix etc..

Hi JJJCR,

Well this was my question really, I am very much a newbie at administration, so I have no idea what standard practice is for this kind of thing. I shall look into these. Thank you.

You don't share the private key, you have a unique one per machine/user, and put their pubkey in only the machines/users that they need access to.
