Hello, I am sorry I could be kind of off-topic. But I want to know how to cross-site rsync without authentication, say ssh auth.,?
I've read some doc. using ssh-keygen to generate key pairs, appending the public keys to ~/.ssh/authorized_hosts on another host to prevent ssh authentication prompt. Is it very risky? Chances are a cracker could compromise one machine and ssh login others without any authentication. Idea? > On Tue, Jan 01, 2002 at 08:39:39AM -0500, Keith Elder wrote: > > This brings up a question.
