[Techtalk] Securely transferring files using scripts

[jennyw]

Thanks, Hamster!  But if I do that, and if the box with the script gets
compromised, won't that give an intruder full access to the second box,
too?  That's what I want to avoid.  I guess maybe I should learn more 
about jails or something?  I'm really hoping there's a software package 
out there that allows people from other machines to drop files onto the 
machine without giving them any access.

The alternative, I guess, would be to have the backup machine pull the tar 
files from the mail server.  That way, the mail server wouldn't have to 
connect the backup machine.  Hmmm....

Thanks!

Jen

You do this by copying the requisite keys onto the other machine (there is doco available on how to exactly do this). It then just uses the key pairs as the authentication method.
