scp issue

[Dewa Negara_4]

Hi All,

I have an issue when I am trying to run scp using private/public keys. Everytime I run scp for the first time, it always prompt me to type "yes" or "no" manually for RSA key fingerprint :

[secumgr@test-box:/home/secumgr/.ssh]
$ scp -q authorized_keys sihp8024:/home/secumgr/.ssh/authorized_keys
The authenticity of host 'sihp8024 (15.1.25.2)' can't be established.
RSA key fingerprint is 99:f8:00:6c:d8:3d:1b:01:3f:16:99:21:a5:98:c9:c3.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'sihp8024,15.1.25.2' (RSA) to the list of known hosts.

This is hard for me because I have more than 200 servers that need to run scp. Is there anyway to do it automatically without typing it manually? or can we avoid to add fingerprint of the server to known_hosts file?

Pls help. High score will be given.

Thanks and Best Regards,
Dewa

Add the "-o StrictHostKeyChecking=no" option to your scp or ssh syntax. This will bypass the lookup in known_hosts file.

Hope this helps,

Doh! I didn't mention that using this option basically answers "yes" for you and adds the host to your ~/.ssh/known_hosts file.

Hi Denver,

Thanks alot for your great help.

The options was working well and it added fingerprint key automatically to known_hosts file.This option really helps me alot.

Thanks again.
