Operating system : CentOS 6 with Parallels Plesk Panel 10 (64-bit)
We can provide our 1and1 control panel where you can reboot in recuse mode but this allows you to reset the root password only so not sure if this helps this situation.
1. Lost ssh admin password our normal method to connect to ssh would be follow
User: admin / Pass: XXXXXX which would then log you in as admin you then type su the 2nd password which takes you in to root.
We have the root password just not the 1st password we would like this removed so once your root password has been entered your in to root ssh
2. We are experiencing some hacking issues taking our server down we recently had fail2ban removed, but then the problems started so we would like it re-installed
3. Postfix we have seen some spam via our mail queue so any suggestions for security here would be appreciated we had our postfix re-write on our previous server for only websites (domains on server can send mail through server this would be a good solution)
