Migrate databases from hacked server

[Richard Rose]

My vps was hacked and the owner was changed to r00t. I was able to connect via ssh and edited /etc/passwd to restore access and successfully copied much of the web sites content except the databases. /usr/bin is owned by my admin user name, nospvs, and I cannot change the owner and group to root. For a while, I had root access and can still cd into all directories.

When I execute the suggested migration command, this is the result:
[nosvps@s132-148-19-193 /]$ mysqldump -u nosvps -p /var/lib/mysql/atlnaacp_db \| mysql -h 192.169.215.15 /var/lib/mysql/atlnaacp_db
Enter password:
mysqldump: Got error: 1045: Access denied for user 'nosvps'@'ip-132-148-19-193.ip.secureserver.net' (using password: YES) when trying to connect
[nosvps@s132-148-19-193 /]$ mysqldump -u nosvps -p /var/lib/mysql/atlnaacp_db \| mysql -h 192.169.215.15 /var/lib/mysql/atlnaacp_db

[nosvps@s132-148-19-193 /]$ effective uid is not 0, is sudo installed setuid root?

Can you offer some help to resolve?
