sudo rm /bin/rm not recommended, but will prevent most rm's :-)

comment Ubuntu Server, 2 Ethernet Devices, Same Gateway - Want to force internet traffic through 1 device (or at least allow it to work!)
Is eth1 connected to a different physical network than eth0? For instance, if both eth0 and eth1 cables are plugged into the same hub or same router, answer "no". If they are plugged into isolated hubs, isolating two non-overlapping local networks of PCs, that would be "yes".

comment What could be so wrong with VPS server that MySQL workbench launch would take 12 minutes?
You can burst to 4 cpus at Linode and it has had good numbers in performance reports.

It isn't tiny. Internet access hiccup?

comment MySQL running but not responding
Are any tables showing as locked? Do your DB ops use locking (e.g., in an app you might be testing)?

comment Our security auditor is an idiot. How do I give him the information he wants?
Why isn't this the top answer? Does that say something about the community, the ease of social engineering, or am I missing something fundamental?

Automated testing is your friend.

comment Internet cafe software for linux
Don't use LiveCDs. Use LiveUSB. The CD drives wear out quicker than you think. Set up a single station as you think it should be, and then remaster from that. A year or so ago there was ubuntugeek.com/… -- there maybe other tools as well. For starters, make login-without-password possible from the console, have some startup scripts in a home directory that start a browser. and have tabs in the browser that point to the big sites like google, gmail, facebook, twitter, etc.

comment Linux freezes every few seconds
Could it be the network/ing that freezes up? I noticed the basic EC2 instances had intermittently sluggish interactivity when I tried the Beta back in 2005. What I was seeing affected both ssh sessions and basic dynamic web pages, like perl CGI.

comment Running game server and webserver on EC2
EC2 will add up at $0.10/hour == $72/mo. Consider Linode, or perhaps a cheap dedicated server.

comment How can I disconnect ssh users, or limit the number of ssh logins?
Random medical information is misdirected all the time, and used to show up on my fax machine much like spam. The number was a swap of digits from a major insurer's fax line. From time to time I toyed with the idea of postal mailing these faxes back to the patients along with a nice note. It was futile to try to block the faxers or talk to the sender or do anything but just shred um.

comment Which distribution of linux is secured and easy to use, for a web server?
Just having two choices does not make a dilemma. Wikipedia, for instance, says that both choices should be unacceptable. In common usage, you usually need a potential tragedy or some element of drama. Godaddy might be that bad :) or it might not.

comment Is there a `tail -f` equivalent for when a file is overwritten (instead of appended to)?
I wonder if screen could be coerced into doing this with some help from a script of some sort.

comment How to hook up a server room?
Keep in mind that running several old computers at the same time will generate heat and can really run up your electric bill.

Caveat emptor Always be suspicious of anything heavily marketed.

comment How to hook up a server room?
gentoo linux is hard for a beginner. All that compiling. I'd suggest Ubuntu. An old electricity-guzzling computer may or may not be faster than a new atom-based one, but atom sacrifices performance to get that energy efficiency.

comment How to hook up a server room?
If you have enough computers and some unenclosed space, you can disassemble them and then bend the cases into any shape wall or ceiling you need. Since the cases will define the room, save the innards for use as the servers. Sandpapering where the cases meet and welding is better than using hooks -- but sometimes you have to use whats available. For internet you can use a pringles can with a dipole in the back, as someone always has an open wifi nearby.

comment Virtualization solutions for a small Linux server?
Getting bridging, etc... working on kvm was difficult and it doesn't play well with Virtualbox. Currently, the kvm kernel module must be unloaded if you want the Virtualbox kernel module to load. That being said, I found either to be quite usable alone. I thought kvm was a bit better for headless / vnc servers and virtualbox was better for UI.

comment Servers harrassed by individual on constantly changing IPs
@Farseeker - Civil sanctions can be useful but a kid offender doesn't have the deep pockets to attract the lawyers. In contrast, you might recall a certain cult church that lost millions of dollars in one such suit, over protesting funerals with outrageous signs and slogans. I realize this is an opinion or a feeling, but there is something unnerving about prosecuting criminally for speech or publication.
