My root password has changed?!!! Proxy was installed?
I used putty to login to my Redhat9 server this morning and when I su -root is says access denied?! Any ideas what could bring this on? Passwords don't change on their own!
Are there any strange processes running? Does last show any odd login times? Is there anything strange in /tmp? Your right... passwords don't change on there own.
Maybe just a typo but make sure there is a space before and after the "-", or just "su -" will take you to root.
Did you recently do any upgrades or install any new software? Sometimes if the user that you are trying to su as is not the the wheel group you can receive a error like that.
Are you able to physically login locally to the server, or is it in a colo facility or something?
Seems i have been comprimised... someone or some script installed a proxy (squid)... what do
u think they wanted to use that used for? And why would it change my root password? And my firewall is gone! And all the logs are gone?
Step 1... unplug network
Step 2... Replace your root password
Step 3... figure out why your firewall was so terribly ineffective
Step 4... shutdown or update any external services
Step 5... plugin network
it's kinda an amateurish attempt, normally one would not want to call attention to the break in, if they want to use your bandwidth for any length of time, by changing the password and deleting the logs.
