Solaris is the best non-BSD UNIX. HP-UX, AIX, and all the dead variants all suck in various ways. Shame on you for using md5 (and thinking modern systems use md5 -- they should be sha-512, suse included, which doesn't preclude sha tables, but md5 is wrong in a few says). SuSE probably hasn't used md5 in this decade. I think they moved to blowfish in the late 2000s, then onto sha, but it's definitely not md5 on anything recent. init=/some/shell would have worked. rd.break=pre-pivot rd.shell also would have worked (after bind mounting /sys, /dev, and /proc into /sysroot for completeness), and dracut isn't much more limited than that rescue shell. I mean, congrats on fixing it and knowing esoterica, but you made it a lot harder than it needed to be in a lot of ways and make it sound a lot harder than it needed to be. In the nicest way possible, the world changes, and you may want to read a RHCSA or SCLA book to get up to speed on current practice. This post is basically one of those pet answers you'd get prompted for in an interview about an rear end-backwards way to do something.

A call came in right as I was laying down to go to bed. The station goes on the air live in 20 minutes and nothing in studio control is responding. Media playback can't locate the server, none of the computers have network access, it's just a bunch of equipment sitting there not knowing how to communicate with each other. Guess who's phone is going straight to voicemail? the answer is the chief engineer I make the drive in and spend an hour and a half rerouting cables and checking for dead switches/ports, but nothing is really turning up. The network is fine in the rest of the building, but in that one room, there's no network access. Well, almost none, the computers can ping the media playout server, but it's getting response times in the several thousands and not responding the rest of the time. I systematically go through and replace every switch (buffalo brand lolololol) in the room but it doesn't make a difference. Long story short, turns out the culprit was the machine that transmits the sensor information for the virtual set. Basically every camera in the studio has a sensor head on it that tracks the camera's location, pan, tilt, zoom, focus, etc... and transmits that information via XLR to an ASR. The ASR then converts that information and transmits it to the virtual server via the network. The end result is the server can tell where the camera is pointing and how far it's zoomed and focuses and can display the virtual set appropriately, relative to the camera's perceived position. Well, for some reason, the drat thing was backfeeding into the network or some poo poo. Who even knows. It's loving midnight and I'm tired. I put an Out of Order sign on the virtual server and they can deal with it until tomorrow. However, it did result in a moderately endearing show where one of the sports guys was literally drawing the graphics on a dry erase board and holding it by the anchor's face. It was kind of adorable.

Yeah, the point isn't necessarily that GMT and UTC are different times (they're not) but that they should be used differently. For example, if you want to use a standard time for people to compare to, then you should use UTC. If you want to talk about what time zone the UK is in during winter, it's GMT. It's pedantry at its finest, really.

My point is basically that "reset a root password in a lab environment" is literally a requirement of the RHCSA. It's incredibly basic and doesn't take manually generating hashes with openssl. I didn't miss that part at all. init has (on some distros, and some alternatives to init) prompted for a root password with 's", "1", or "single" for a long time. init=/some/shell will never do it. A bootloader password could block you, but that would have come up in grub (and not prompted about root) It could have been md5, but that's a setting they'd need to have changed manually, because SuSE doesn't default to it. They carried a patch for blowfish (and defaulted to it) since 9.something, and switched to SHA in 2010. But... As said. It's an interesting anecdote, and props for knowing esoterica, I'm just trying to get across that resetting a lost root password should not be this hard. For people reading it who don't know Linux, it isn't this hard. At all. You don't need to manually generate hashes. It's a well-documented process that pretty much everyone with a basic cert knows off the back of their hand. It has changed (like "single" not working anymore, and needing to pass init=), but it's still easy.

Maybe people would care more about what you post if 90% of what you posted wasn't dickish or if when called out on it you didn't just say "Well I don't care what you guys think about me anyway."

Hehe, accolades from GM in front of supervisor today. GM came and wanted a rundown on last night and supervisor kept trying to interject his opinions and every time he talked, GM would just look at him and go back to talking to me. Then he thanked me and called me a hero. His exact words were, "It's nice to know I've got at least one person on staff I can count on in an emergency," and then he shot a death glare at supervisor. Now supervisor won't talk to me

Again, I really don't give a poo poo what you think or how you receive what I say. "Quality poster" wasn't a response to anything you think about what I say. It's that I also discard your posts. "Props on knowing esoterica" is as far as I'm willing to go. "Nice thinking on your toes" implies that anyone who can rub two brain cells together to pass an RHCSA or LPIC doesn't know the ways I suggested (which they do). It was a completely backwards way to go about things.

Edit: I know this is anecdotal but. I have two customers with mixed AIX/Solaris shops. Each has experienced a complete datacenter power loss in the past 6 years or so. In each case, they basically powered on their networks, then storage, then powered on their servers. All the IBM machines were happy and processing again with little to no intervention, while it took each customer a week to tease all the tangles out of Solaris.

I've seen stupidly high uptimes for both AIX and Solaris systems. It's funny how they run until the power goes out. For the Solaris shop, a huge number of reboot stability issues I've seen were solved by enforcing UFS logging. After that, weekend pages from reboots dropped to 10% of what they were. It wasn't the default build for a long time. I think AIX has journaling on out of the box. E: I should add that that shop was enforcing frequent reboots to solve application stability issues, not the fault of Solaris. But without logging, the systems would always come up needing manual fsck. 18 Character Limit fucked around with this message at 16:36 on Oct 15, 2015 |

I was more of an OpenSolaris fan, though I did like 10 more than AIX6 (AIX 4 being an obvious mess, and 5L being better than Sol9 and below). Solaris and AIX are both pretty stable (minus the already mentioned UFS problems, but ZFS-on-root is ok). SVM is an obvious mess that nobody should use, but that I've run into way too often in Solaris shops. Loved the hardware, hated AIX, and I can't even really put my finger on why. Heavy usage of inittab? Maybe. A bunch of variant-specific commands? Maybe, but that applies to every UNIX. LPARs? Maybe (they're cool, I just like zones better). At least it's still better than HP-UX.

I'm not sitting here beaming about my little pat on the head. What I am beaming about is that this momentary spotlight on my reliability has taken the spotlight off of my supervisor and he is absolutely fuming about it. It's actually hilarious how childish he's acting about the whole situation. I got in and started undoing all the temporary cable runs I made last night and putting things back the way they were, and every few minutes supervisor is trundling in and grasping at straws to point out every conceivable way I could possibly be wrong or have hosed something up. "I've seen this before when a network card dies. It's probably a bad network card somewhere." "What made you think it was the ASR? Why would you even check that?" "It's probably a virus" "I've seen etherblasts before and this is probably an etherblast." (what) He wants so hard for this to be my fault, or for me to have not actually diagnosed or fixed anything. He can't stand for something to be going on without him viciously rubbing his grubby hands all over it. Not to mention, everyone that was affected by this has been going by his office one by one and ragging on him for not answering his phone. This poo poo waterfall has temporarily been redirected onto him, and gently caress yeah I'm going to enjoy it for what it's worth. But don't make the mistake of assuming I'm sitting here thinking that things are finally turning around for me.

Nice. The guy is reaaaaaaaaaaaaally unstable sounding. Whole place sounds like a terrible high school. I once had a network go down and had no idea why. Turns out a network card was partially broken and was just spamming the gently caress out of the network. So, maybe that's an etherblast?
