I'm currently testing running restores from AWS EC2 Snapshots.
We have various Ubuntu instances in AWS EC2, most of them we use the AWS Key authentication and have had no problems logging in after restoring from volume snapshots.
However one of our servers is an FTP Server and has password authentication enabled, and we cannot connect via SSH using the Ubuntu (SU) account, we just get a message saying access denied.
Oddly we can still connect to the FTP Server via FTP with all the other accounts.
I'll be honest I'm not an Ubuntu expert, but do we need to reset the password here? If so how do we go about doing this in EC2.
I really appreciate any help anyone can give.
EDIT: The exact error message is 'Access Denied' I know the password is correct as using it on the original version of this server still works.I guess what I'm really asking is, is there a reason the password would change following a snapshot restore. I can also ping the machine, telnet to port 22 and connect to SFTP.
