Reverse Copy

I nearly forget about reverse copy. Yasterday sis Salina have problem to copy file for Server Source to Server Destination.

Here is the way where we can pull the data ( reverse copy )
Normal copy ( copy command at source server ) source -> destination
Reverse copy ( copy command at destination server ) destination  <- source

For example you want to copy DATA from Server S (source) to Server D (destination):

Normally at Server S
# scp /path/to/DATA aminah@ipServerD:   -> file akan ada kat home/aminah/
# scp /path/to/copyDATA aminah@ipServerD:/path/to/save/  -> file akan ada kat /path/to/save/

But for reverse copy, we copy DATA to our home at server S.
-> so at server S we have /home/aminah/DATA

At Server D 
# scp aminah@ServerS.contoso.com.my:DATA ./

Reverse SCP for amazon
#scp -i mykey.pem root@ec2-184-73-72-150.compute-1.amazonaws.com:/file/path/filename ./

./ -> mean current directory 

Normal SCP for amazon
#scp -i mykey.pem filename root@ec2-184-73-72-150.compute-1.amazonaws.com:/path/to/save/ 



hehehe... done..  

Cannot SCP your file to another server

Usually.. I have no problem to scp my file to another server.. But today it giving me below error :

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending key in /root/.ssh/known_hosts:11
RSA host key for 1XX.1X.XX0.xX0 (ip) has changed and you have requested strict checking.
Host key verification failed.

-----
So, here is the step to resolved this problem
#cd /root/
#ee .ssh/known_hosts
pastu ctrl-k semua line dalam tuh..
save..

Actually this .ssh/known_hosts file keep cache of previous access ssh command.

Then ok.. :) paham2..
