Dear friend, I have installed ubuntu 8.04 lts in two new machine and again i follow some steps. Source pc > 1> root@jiten-desktop:/root# ssh-keygen -t rsa 2> i get id_rsa.pub and id_rsa both key in /root/.ssh folder. 3> ssh <a href="mailto:root@10.0.1.81">root@10.0.1.81</a> address in destination pc . login there 4> After that when i use scp command in destination pc to source pc " scp -r root@10.0.1.82:/root/.ssh/id_rsa.pub (Source Pc) root@10.0.1.81:/root/.ssh/ (Destination Pc) then it is giving me permision deny error. When i use scp command for copy.(when i run that command that time i am login in destination pc) 5> When i run scp command source to destination then it works.(With out ssh ) 6> scp -r root@10.0.1.82:/root/.ssh/id_rsa.pub (source) root@10.0.1.81:/root/.ssh (destinection) 7> chmod 700 id_rsa.pub 8> vim /etc/ssh/sshd_config 9> PermitRootLogin = yes 10> /etc/init.d/ssh restart/reload/start in source pc and Destinetion pc. 11> In a "souce pc" ssh <a href="mailto:root@10.0.1.81">root@10.0.1.81</a> Then it is not asking for root password AFTER THAT I RUN THAT COMMAND IN (DESTINATION PC) 12> when i run rsync -r -v -a -e ssh /home/common/Desktop (destination ) root@10.0.1.82:/home/common/Desktop (Source PC) (when i copy destination "Desktop" to source "Desktop" ) then i get that error. root@common:/home/deepak# rsync -r -v -a -e /home/deepak/Desktop/ root@10.0.1.82:/common/Desktop rsync: Failed to exec /home/deepak/Desktop/backup: Permission denied (13) rsync error: error in IPC code (code 14) at pipe.c(86) [receiver=2.6.9] rsync: writefd_unbuffered failed to write 4 bytes [receiver]: Broken pipe (32) 13> when i run rsync -r -v -a -e ssh /home/common/Desktop/java.pdf (Destination ) root@10.0.1.81:/home/common/Desktop (Source) When i run this command as a normal user then it gives following error. chandan@common:~$ rsync -r -v -a -e ssh /home/chandan/Desktop/test.css root@10.0.1.82:/home/common/Desktop The authenticity of host '10.0.1.82 (10.0.1.82)' can't be established.

It should be there by default if you're using Ubuntu on it. Also, just out of curiosity, did you set a password on your ssh key? When creating your ssh key it prompts for an *optional* password. If you entered one in at the prompts, that might be the password it's asking for. If you did provide a password when creating your ssh keys, and don't want to use a password with them, you'll have to re-generate your keys and just hit 'Return/Enter' at the password prompts. This will create a set of keys that don't require a password. <div><div></div><div class="h5"> >> In the above steps, you don't indicate which machines you're running >> those commands on.
