|
|
Hello,
Most of the time, my CPU util was near zero, but since 12.00 CET (exactly), that is to say, since 5 hours ago, I have rather constant 1.5% utilization. In addition, it uploads at 6 Kb/s, and downloads at 4 Kb/s constantly.
The strange part of the story is that "uptime" gives me a 0.00, 0.00, 0.00. What do you think about this? Has a rootkit infected my server?
I am puzzled at how constant those rates are over time.
Thanks,
Laurent. |

| Do, as root or sudo, 'netstat -t -u -n -p', which will list all active connections, along with the process responsible. (You'll see some without a process that are in mode "TIME_WAIT". That's okay.) Determine whether or not the processes are valid and explain the traffic. If not, time to install a root kit checker. Not a bad idea anyway. |
