Hi Unix gurus,

I am trying to create a script to automate the copying of files daily from one server to another using the scp command.
-->
#!/bin/ksh

KEY="$HOME/.ssh/SSHKEY"

if [ ! -f $KEY ];then
echo "Private key not found at $KEY" >> $LOGFILE
echo "* Please create it with \"ssh-keygen -t dsa\" *" >> $LOGFILE
exit
else
echo "Transferring files.." >> $LOGFILE
echo "scp -v -i $KEY $FILES $SCP_LOGIN@$SCP_MACHINE:$SCP_PATH" >> $LOGFILE
scp -v -i $KEY $FILES $SCP_LOGIN@$SCP_MACHINE:$SCP_PATH >> $LOGFILE
echo "Copy files successful.." >> $LOGFILE
fi

My questions are below:
1. Whenever I ran this script, it no longer ask for password but it still prompts the "Are you sure you want to continue connecting (yes/no)?" question:
See details below:
-->
Putting your key on remote server
Transferring files..
The authenticity of host '10.68.169.168 (10.68.169.168)' can't be established.
RSA key fingerprint is cd:78:a1:fe:2d:8d:aa:0f:32:be:18:5b:74:0e:3a:c1.
Are you sure you want to continue connecting (yes/no)? yes
Failed to add the host to the list of known hosts (/shared/home/ngtman/.ssh/known_hosts).

Can I also automate it in a way that it always answers yes to the above question w/o me typing anymore?

2. How can i display the error messages of the scp in the $LOGFILE for cases that scp was not successful for some files?
i.e. there are space issue with the remote server, connection time out, or permission issues. I just want to see in the log what happened to
the scp so as it would also be better for the support guys to check as in case anything happens.

I tried both redirecting using >> and using the tee command but both not writing to the logfile, only displaying the status in the prompt.

Hoping to hear from you guys.

Thanks in advance.
