comment same SSL certificate in two servers
I'm not aware of a cert that is machine specific - it can't be: It certifies the authenticity of the private key in combination with the FQDN. Once the private key is known to another machine, this machine can - under the same FQDN - operate with the same key and the same certificate without problems.

thanks for accepting this as an answer - can you provide some insight into what exactly helped to solve your problem?

and: Don't rule out malware just because you doubt that it's there. This can be quicker than you think. Check it, double check! Remember: you're observing some strange behaviour after all.

MD5 is there for you to be sure that you've got the correct file even when downloaded from a mirror site. Make sure to always get the MD5 from the original site, not from the mirror. Have you tried https (or ssh or anything encrypted) yet? If this is also corrupted, everything in the network can be ruled out. If it is not, there might be some eavesdropping component on your way - e.g. a proxy running virus checks or something else. Are all your problems from varying sources or all from the same source? Can you post links to check?

comment tomcat6 on ubuntu fails when user set to root
+1, never run as root. If you really need to execute another process from your webserver, there are other options - compile a stub that runs as root, create a daemon and communicate with it etc. Don't go the easiest way just because that the first thing you think about. To answer the original question: You can diagnose what you do wrong by looking at your post: "TOMCAT_USER=root" is what is going wrong. Seriously. Really really seriously.

comment How many users are “many users”?
right - that's what I had in mind: Make sure that the database doesn't have to touch the disk on read. Regarding swapping: You don't want any swapping to happen if you optimize for high load. Might as well disable swapping to come to a hard stop instead of degrading performance when memory is exhausted.

comment mod_rewrite redirect from SSL to HTTP not working
+1 for the answer: I've seen way too many problems with mixed setups. You will find holes. They will be unexpected. No matter how many you've already plugged - seriously.

comment created pub/priv keys using putty, created .ssh folder and authorized_keys, still not working
This is the issue I've most frequently been bitten by after learning that Putty and OpenSSH use different formats for their key files.

comment Picking up the pieces after missing Linux admin
fully agreed, but as the system is already live, I guess there's no way around learning on a live system.
