Sync of Users and directorys
I need to have a warm standby server, so I need any users setup on one machine (and then its ftp accounts and ssh logons and so on) automatically copied across, I have looked at NIS but there home website is rather confusing and I am hoping there is something better?? anybody got any pointers on the best way to do it...
Also I was thinking of using rsync to replicate some directorys and so on, is this the best way to go???
There is a good chance I am looking at this wrong, any help would be great.
Note: to give more information, I have 2 servers and if one falls over I will just change the IP's and people can then connect directly to the new server, they should then be able to connect to the new machine using the same username and passwords and drop files off into the same directorys.
When the other machine is then brought back online (booted up off the network to change IP again) this must then be configured to be the warm server... make sense???
