unabel to ssh from script.

I can execute a ssh command from the command line.
ssh remote_server date
Tue Oct 7 15:39:37 EDT 2008

I have set this up to use key authentication.

I am trying to run the same command in a simple shell script and it fails to connect. Here is the script.

$ cat ssh_test.ksh
#!/bin/ksh
ssh -v -v -v remote_server << EOT
date
EOT
if [ $? -ne 0 ]
then
echo failed
exit 1
fi
exit 0

$ ksh -x ssh_test.ksh
+ ssh -v -v -v remote_server

All help to resolve this is greatly appreciated.

It's pretty clear that it cannot parse your key file. Do you get a different version when you run it from the prompt?

Thanks for the insight Era,

I ran the same script to another remote server that has the same OS and SSH version as the remote server I can not connect to. The script works.

Should I be looking for something in sshd_config? OS patches?
# 4  
If I change my shell script from:
$ cat ssh_test.ksh
#!/bin/ksh
ssh -v -v -v remote_server << EOT
date
EOT
if [ $? -ne 0 ]
then
echo failed
exit 1
fi
exit 0


to:

$ cat ssh_test.ksh
#!/bin/ksh
ssh -v -v -v remote_server date
if [ $? -ne 0 ]
then
echo failed
exit 1
fi
exit 0

it works. I was hoping to be able to use the <<EOT....EOT syntax because I want to expand this script to be able to use if statements and several commands. I was hoping not to have to put a script on each remote server. Over 100 remote servers I need to connect to.

Is there something obvious that I am missing?
# 5  
Passing in commands over standard input works for me here. You can pass in a fairly complex script in single quotes just as well, though -- just take care not to try to use single quotes in the embedded script /-:

Code:
ssh remotehost 'date
if grep -q fnord /etc/motd; then
  echo I have seen the fnords
fi
sleep 30
while read line; do
  echo "$line"
done <<HERE
Confusion
will be my epitaph
as I crawl
... whatever, missed that line
