scp still ask for root 's password when executing...


scp still ask for root 's password when executing...
last june I have tested scp and have written down notes on scp implementation. When I do again next week I went into problem.


both machines are sitting side by side but eventually one of them has go some where at least 400 miles away.

watch my steps:

1. exchange and store /root/.ssh the rsa generated by ssh-keygen -t rsa
2. it generates the fingerprint but my note tell me to do nothing.( copy or paste somewhere)
3. enter no password when asked for password.

in the destiny server I have a script like this
/usr/bin/scp -o protocol=2 -C -c 3des -4 -v -r -P 22 -i /root/.ssh/authorized_keys4 root@192.168.0.199:/var/www/html/redhat7.3/somesorucedirecoty/*.* /home/mydestinybox/save/



my /etc/ssh/sshd_config in source linux redhat 7.3 server.



# $OpenBSD: sshd_config,v 1.48 2002/02/19 02:50:59 deraadt Exp $

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a

I do not call from my notes that I need to do the some setting of the destiny server.

There is an excellent series of three articles written on the subject. As I understand it, to use a password free authentication you also have to use ssh-agent and then ssh-add. These articles can be found at:

http://www.gentoo.org/proj/en/keychain.xml

In section 4. they have the three links to each of the three articles.

Hope this helps.
