Preventing My Hosting Provider From Rooting My Server?
hacker writes "I have a heavily-hit public server (web, mail, cvs/svn/git, dns, etc.) that runs a few dozen OSS project websites, as well as my own personal sites (gallery, blog, etc.). From time to time, the server has 'unexpected' outages, which I've determined to be the result of hardware, network and other issues on behalf of the provider. I run a lot of monitoring and logging on the server-side, so I see and graph every single bit and byte in and out of the server and applications, so I know it's not the OS itself. When I file 'WTF?'-style support tickets to the provider through their web-based ticketing system, I often get the response of: 'Please provide us with the root password to your server so we can analyze your logs for the cause of the outage.' Moments ago, there were three simultaneous outages while I was logged into the server working on some projects. Server-side, everything was fine. They asked me for the root password, which I flatly denied (as I always do), and then they rooted the server anyway, bringing it down and poking around through my logs. This is at least the third time they've done this without my approval or consent. Is it possible to create a minimal Linux boot that will allow me to reboot the server remotely, come back up with basic networking and ssh, and then from there, allow me to log in and mount the other application and data partitions under dm-crypt/loop-aes and friends?"
Read on for a few more details of hacker's situation.
"With sufficient memory and CPU, I could install VMware and run my entire system within a VM, and encrypt that. I could also use UML, and try to bury my data in there, but that's not encrypted. Ultimately, I'd like to have an encrypted system end-to-end, but if I do that, I can't reboot it remotely without entering the password at boot time. Since I'll be remote, that's a blocker for me.
What does the Slashdot community have for ideas in this regard? What other technologies and options are at my disposal to try here (beyond litigation and jumping providers, both of which are on the short horizon ahead)."

.. just switch providers. I'm sure there are companies that treat you better.
Be sure to stun them as soon as they start casting it.
1. Don't EVER host with them again. I don't know what's in your contract but as far as I understand it, breaking into your server without your permission is illegal. It's possible that you could take legal action against them.
2. Figure out how they broke in. If they broke in then someone else likely could too.
I have never heard of anything like that happening with any host ever. I am amazed that a company could act like that and still expect to have any customers. It's not like there aren't options.
On the other side of this, your hosting provider has a guy who keeps angrily reporting mysterious outages where his machine keeps running even though he's on a trivial switch connection like everybody else. The guy then refuses access when they try to figure out what's going on so that they can fix it.
They shouldn't be rooting your server. That crosses a line. But if I were in their shoes, I'd say: "I'm sorry sir; we've exhausted our diagnostic capabilities without more closely examining your server. Without the root password, there's nothing more we can do for you."
Moderating "-1, Disagree" is simple censorship. Have the guts to post your opinion.
As someone that works in support for a hosting provider, you're the type of customer that irritates me the most. While they shouldn't be rebooting your box to get root access without your consent, you should at least help them help you. Give them an account with limited sudo access to view your logs. If that won't do, then provide them with the necessary logs. If that's not good enough, don't expect support and move your stuff to some place that doesn't provide the level of support you're paying for.

Some things are only solved by replacment.

They have KVM access and forcibly reboot the server, and when it comes back up, they enter it in single-user mode. They've done this at least 3 times before, while I was logged into it, and when the server came back up about 15 minutes later, the lastlog for my own login was missing from the logs. They attempted to clean up the logs to hide their own activities.
Okay, since a lot of Slashdotters run their own servers rather than utilize the services of a web hosting company, let me provide some background info. I don't know whether the OP is one of our customers or not, but at the web hosting company I work for, there are two ways to host your server with us:
1. You can co-locate your hardware with us and purchase a unmanaged plan where the only support we offer is reboots and network troubleshooting. Everything else from the OS to web applications is your sole responsibility.
2. You can rent a server from us, which comes with full managed support, meaning the box is provisioned and configured by us, and our techs have full root access to your host in order to resolve any problems that come up. All services on the machine are monitored by Nagios, so we know (and react) within 5 minutes when a service stops responding.
You don't specify which hosting plan you have, but from your description of your problem, it sounds like you purchased #2. All of the things you describe are exactly what our technicians would do if we were charged with keeping a managed server online and a customer was making that task impossible to do. If a customer is asking us to fix a problem and is only making it worse or more difficult by virtue of their incompetence, we have been known to lock them out of their own server until the problem is fixed.
The bottom line is: don't rent a managed server if you don't want managed service. If you want full control over your hardware, you need to talk to the sales team and tell them that you want an unmanaged plan. The trade-off, of course, is that you have to deal with your own "WTF" problems from then on.
