Hello Everybody,
I have a query. Right now I have 5 machines all of them are connected in LAN.
They are Pentium 4 machines with 1 GB RAM and 80 GB HDD. On all of them I have installed Fedora 11 separately. And created one normal user on each of them. My problem is I cant't access all the accounts from one system. If I have to check or solve any problem on these systems I have to go there separately
.
So can somebody tell me how to make a small network, in which as a administrator I can control all these five machines from one terminal?

Also whether I have to dedicate one extra machine as server or I can use any system as administrator just by logging in as root?

And whether I have to install fedora on only one machine or is it ok that I am having separate fedora on each of them?

And can I use different distributions(ubuntu,fedora.opensuse) in this kind of setup?

Thanks for your help...

You can use LDAP to centrally manage the authentication
You can use cluster ssh to simultaneously run commands on multiple machines
You can use cfengine to maintain coherent configurations across similar machine groups
You can use NFS or a cluster filesystem to export/share common files, binaries

Generally, look at cluster management tools, even if it's not strictly a cluster.
