I have to connect to two different URLs, which share the same IP address. The first one I connected to worked fine, and still does. The second one give the following message:


Warning: the DSA host key for 'URL' differs from the key for the IP address 'xxx.xxx.xxx.xxx'

The system asks whether i wish to proceed, I answer yes, and it connects just fine.

However, i have automated SFTP process that will login in the same manner... SSH? So the first one I tried works fine, but the second fails because I would need to supply a "Yes" during the automated process.

My question is, can I add the second URL to the key that currently has the first URL and corresponding IP?

Kindest regards to all,

You can use the StrictHostKeyChecking option in SSH to ignore the check and proceed anyway:

Can I turn this off permanently? a setting perhaps, so it does not use the StrictHostChecking at all? I trust the servers I am connecting to.

Thanks for the info,

Not sure if you can globally disable it, but you can always add an alias so every time you type "ssh", it actually runs "ssh -o StrictHostKeyChecking=no".

cause i won't be typing it in, its a php program that executs the connection. I'm looking at the code to see if i can squeeze that stricthostchecking=no. but don't think its so straight forwards. I see where the code ... i'll dig deeper and post again, when i know what to post.

thanks a million!

Just correct the corresponding hostname in ~/.ssh/known_hosts.
