It turns out this is far from trivial.

comment sshd running at 100%
Snother idea is to check logs or issue lsof to find out whether any ssh connections are being made or attempted at that time.

comment How to block ports (in Linux) based on the IP used to connect?
My guess is that the downvote is because you didn't explain where exactly you got stuck. It's as if you didn't even try.

comment How to block ports (in Linux) based on the IP used to connect?
man iptables or use Google. I don't find this stuff (e.g. 'chains' in iptables) very easy but I do find the answers that way. BTW I think it's better and easier to just block all incoming traffic (rule 1) and then open port 80 (rule 2).

comment Ubuntu - How can I see what an IP is doing in my server?
You can check out the ancestors of the process with pstree and you can see what it is doing at the system call level with strace.

comment Can a virtualized machine have the CPU and RAM resources of multiple underlying physical machines?
To be more precise: disks can be combined in this way (it makes sense, as network speed usually greatly exceeds disk access speed), while memory and CPUs cannot (the resulting virtual memory and virtual CPU would be too slow).

comment Open Source Terminal Server For Linux?
PS: Last montI i set up an Ubuntu 12.04 system, and I went looking for a way to provide GUI sessions from Windows machine. What I ended up with was the TightVnC server, which supports GUI sessions that can be connected to remotely, combined with xrdp, which provides a bridge to the RDP protocol, allowing the standard Windows Remote Desktop client to be used for access - and in addition, it makes TightVNC start a new session upon connecting and shut it down when the session is closed.

I compiled the current unzip-6.0 from scratch - it didn't fix the problem.

Perhaps you can monitor for two log rotation instances or prevent that from happening.

Locking-related, is my next guess. Who is doing the locking?

comment Cannot remove or list directory (ls or rm) Linux - Debian
Your /var/log is on a local disk, right? Mounting it from another machine might lead to problems like this.

OK ... you can check the /proc filesystem or use the lsof command to see which processes have which files open. I'd also check the logs in /var/log to see if your disk is dying. I'm really just guessing here.
