ssh DSA Key fingerprint option

Hi,

I have an cron-script running ssh every 5 minutes. After a reboot cron errors as ssh is wating for a DSA key fingerprint authenticy.

The request looks as following :

The authenticity of host '*** (*.*.*.0)' can't be established.
DSA key fingerprint is 11:59:*4:46:21:2*:e0:77:db:55:*2:*e:*1:*2:*9:*6.
Are you sure you want to continue connecting (yes/no)?

Of course * are modified for security reason. When I enter "yes" one time, the question will disapear untill the next reboot.

Does anyone how to avoid this question , or how I can get stdin to work, so that :

echo yes | ssh -tttt <server> <command>

will work ? This to avoid anoying error messages when my system reboots and I accidently forget to run an ssh manualy.

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be enabled, unless you've done some clever use of multiple identities) It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth- erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration). If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your ssh-agent. Otherwise, if this: ssh-add -L provides any output, it uses that in preference to the identity file. If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin- gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory, if necessary) SEE ALSO
