Hacked? Cant' login & blank screen.


Last night I went to check my email (remotely) and was rejected. I then tried to ssh (as a wheel -- root can not ssh) and was also rejected. No other user can log in for mail. All the internet services are responding; I telneted in on all the ports to check them. The web page appears untouched.

I was thinking that I was either hacked or the "passwd" (or "shadow") file got corrupted.

So here is the odd part: on boot, immediately after the kernel selection (or default time out) the screen goes blank. The machine seems to boot and work fine (except for the password authentication) but the screen is blank. Has anybody seen this? There are several different kernels install and all act this way when booted.

The machine is physically secure and there are only two of us wheels. Unfortunately, I am away for the weekend and haven't been there to personally inspect the boot symptoms. The machine has been, until I get back home, turned off.

Well if he was a clever hacker he would've left the password unchanged, installed whatever dirty trick he had up his sleeves, left the machine in an apparently untampered state, while unbeknownst to you he has complete control over your computer, all for coordinating some evil terrorist scheme. ... Or atleast deface your website. Maybe the other "wheel" is behind it all. Watch him carefully.

Well how could I have any idea? How would I know your monitor is'nt dying out? How would I know if its just simply an X problem? How do I know you're not just simply forgetting your password?
How could I know anything?



What do your log files tell you?

If they had tried to get into your system, it would have been obvious than saying you have no access. How is your Network traffic, is higher than before? Any new ports listening? ......

This is not easy to guess. You can't say that ur computer was hacked or something untill u get access to ur log files.
15 days back, my computer was cracked as I could see the ssh login attempts, password change messages, new user additions, etc.
In ur case, it might be anything, a power failure, file curruption, system malfunction. etc etc.
We are not magicians my friend, just a bunch of linux users like u r. Yes, maybe we can help u after u post some more details.
