[NTLUG:Discuss] Using scp....

[Douglas King]

I had someone set up my Linux machines to use SCP as the "backup" feature 
every night.  However, I have had to rebuild a couple of the machines, and 
need to set up SCP again.  When the "backup" machine logs in, it's asking 
for a password.  There is supposed to be a way to "fix" the passwords in 
the respective machines so that when it gets to that stage...it logs an and 
backs up the designated directories.  My QUESTION is....what is the process 
in "fixing" the password stuff, where it doesn't stall there?
