connection manager system in network
Hi!
I just wanted to know what's your opinion on my problem.
I have few linux servers that can be located on any place in the world, only port 22 is open. At my office I need connection to every server, but every server must be isolated from every server.
So by now I worked only with ssh authorization by username and password.
What seems to be preferable ?.
1 Going on working with ssh with authorization.
2 working with ssh but with adding keys
3 start to work with vpn
So if I am keeping use ssh with authorization I need something that will change password every month only for security
working with ssh key, it seems like key depends on gateway where key created so if change gateway I lost connection
using vpn sounds good but in this case I mush isolate servers from each other
The best solution I think is combination of any two methods
So what do you think
If anyone has experience in this area please tell me
I will appreciate for further reading
Thanks
