using bootlocal.sh to scp

[ambaum01]

I am trying to create a text file and write that text file to a server automatically upon boot.  When I execute the following command in terminal after boot, it successfully scps the file:

scp /home/dir/file.txt username@SERVER:/company/dir

When I put that line of code in bootlocal.sh, I got the error:
 

ssh: Could not resolve hostname SERVER: Name or service not known
lost connection

So I figured it was a timing thing, so I added a long delay:

sleep 60
scp /home/dir/file.txt username@SERVER:/company/dir

But now I get the error:

Host key verification failed.
lost connection

Is this caused by trying to use scp too early in the boot process?  Is there a better way to automatically transfer the file as soon as possible after boot?  Thanks.

Have you restored all keys in ~/.ssh at boot?

Hi tinypoodle
Since bootlocal.sh runs as root, wouldn't that be  /root/.ssh ?

[tinypoodle]

Good catch!

Might be a possible explanation why the command works when interactively executed as tc, but not in bootlocal.sh

Alternatively perhaps invoking su(1) to run scp as tc could be an approach.

Hi tinypoodle
So maybe something like

Code: [Select]

su tc -c scp /home/dir/file.txt username@SERVER:/company/dir

[tinypoodle]

su tc -c 'scp /home/dir/file.txt username@SERVER:/company/dir'
or
su -c 'scp /home/dir/file.txt username@SERVER:/company/dir' tc

[ambaum01]

su tc -c 'scp /home/dir/file.txt username@SERVER:/company/dir'

This works wonderfully!  Although, I do have to put sleep 1 before it.  Thank you very much!

Glad I could help, but it was rather Rich pointing out the core of your issue

You omitted to mention which scp you are using, assuming openssh, in case of dropbear an additional parameter of "-i /path/to/identityfile" may be required.

[ambaum01]

Just to follow up, I did not have to include -i /path/file.  I assume it's because I did not rename the public and private key file names.
Thanks to all who helped out.

Just to follow up, I did not have to include -i /path/file.

It would be more useful if you could clearly state which ssh version you are using...

[ambaum01]

I'm using OpenSSH_6.0p1, OpenSSL 1.0.0i 19 Apr 2012

So that explains why the "-i /path/to/key" may be omitted; OpenSSH searches in a default path, while with dropbear the path option appears to be a mandatory statement (SSL is without relevance).
