The Chuck Yerkes Award is presented annually in recognition of outstanding individual contributions in [system administration] online forums. It was created after Chuck Yerkes' untimely death in 2004 to memorialize the mentorship he provided countless systems administrators through his helpful and accurate posts to systems administration mailing lists.
Since 2009, LOPSA (The League of Professional System Administrators) determines and presents the award to someone who followed Chuck's example in their contributions to system administration online forums--whether mailing lists, web forums or chat rooms. 2005-2008 awards were presented by the USENIX Association.
According to alerts coming from IRC, I found that I got the award during the "Opening Remarks and Awards" portion at LISA '13 conference in Washington, DC.
I knew I had been nominated, but hadn't heard anything after that...so I'd be curious to see what get's written up on me officially, etc.

So, the announcement of FreeBSD 9.2 came out on Monday [September 30th], which I missed because I was focused on my UNMC thing. But, once it appeared, I knew that I was going to want to upgrade to it sooner than later.
From its highlights, the main items that caught my attention were:
But, I did start this upgrade on October 4th....where for an unknown reason, I launched the
freebsd-update process on cbox, the busier of the two headless servers. I suspect I went with doing the upgrade on my headless servers, because they are entirely running on SSD and would likely see the benefit of lz4 compression. And, perhaps I did cbox, because it was the system that could most gain from lz4.
It took a couple iterations through
freebsd-update, before I got an upgrade scenario that could proceed. And, it took a long time given the high load that is cbox.
That is cbox is an Atom D2700 (2.13GHz, dual core) processor. And, cacti (especially with the inefficient, processor/memory intensive percona monitoring scripts -- might help if only scrpt server support worked, and wasn't just a left over from what it was based on.) being the main source of load. That is usually in the 11.xx area, except during certain other events (like, since 3.5, when
cf-agent fires...cbox is set to run at a lower frequency than my other systems.) or when the majority of logs get rotated and bzip'd. And, there's also some impact when zen connects to
rsyncd each day for
backuppc. But, these spikes weren't that significant. Though the high load would cause
cf-agent runs to take orders of magnitude longer than other systems, including its 'twin' dbox.
Also ran into a problem (again?) where a lot of the differences that
freebsd-update needed resolved were differences in revision tags....some as silly as '9.2' vs '9.1', others had new time stamps or usernames, but seldom any changes to the contents of the file. Which I then discovered a problem from having some of these files under
cfengine would revert these files back to having '9.1' revision strings, which confused the
freebsd-update. I ended up updating all the files in
cfengine to have the 9.2 versioning, though I thought about just removing/replacing it with something else entirely, though wasn't sure the impact that would have on current/future
Though it did seem to cause problem with the other two upgrades, where it would say that some of these files were now removed and asked if I wanted to remove these. Which doesn't make sense, since it didn't say that with the first upgrade. It was probably just angry that these files already claimed to be from FreeBSD 9.2.
It also didn't like that I use
sendmail, therefore my sendmail configs are specific to my configuration, or that I use
printercap is the one auto-generated by cups, etc.
But, once it got to where it would let me run my first "
freebsd-update install". I ran it, rebooted, ran it again, rebooted, updated stuff (though it didn't complain as much, perhaps because some of the troublesome kernel mod ports had corrected the problem of installing into
/boot/kernel, or perhaps enough stayed the same between 9.1 and 9.2, that things didn't freak out like before. And, this includes the virtualbox kernel mod, when I did the upgrade on zen, and later mew. But, I re-installed these ports and lsof. I did a quick check of other services, and then upgraded the 'zroot' zpool to have feature flags (which now means it no longer has a version, apparently instead of jumping the numbers to distinguish from Sun/Oracle it has eliminated having version numbers (for beyond 28) and having flags for the features added since. Wonder if the flags capture all has changed since 28, since I thought there have been other improvements internal that aren't described by version numbers. Namely, I seem to recall that there have been improvements in recoverability....namely it had been suggested, when I was trying to recover a corrupt 'zroot' on
mew, to try finding a v5000 ZFS live CD. Which I don't think I ever found, and gave up anyways when I concluded the level of corruption was too great for any hope of recovery and that I needed to resort to a netbackup restore, before the last successful full get's expired. Though being that it was nearly 90 days old, the other two month fulls didn't exist due to system instability that eventually caused the corrupted zpool (eventually found to be a known bad revision of the Cougar Point chipset and a bad DIMM...things seem to finally be stable from using a SiI3132 SATA controller instead of the on board, and getting that bad DIMM replaced....was weird that it was a Dell Optiplex 990, purchased new over a year after the problem had been identified and a newer revision of the chipset was released. I did eventually convince Dell support to send me a new motherboard and replace the DIMM. The latter was good, since I had to use DIMMs from another Dell that had been upgraded, so I had less memory for a while. But, while at first I did use the onboard SATA again, eventually I started having problems that would result in losing a disk from the mirrored zpool, to eventually causing a reboot where they would both be present again [though gmirror would need manual intervention]....and moving back to the SiI3132 has finally gotten things stable again. Though the harddrives in mew are SATA-III, so it would've been desirable to have stayed on the SATA-III onboard ports, where it was these ports that were the main source of problems in the prior defective version. Perhaps the fact that the prior version had a heatsink and the new version didn't, wasn't because they didn't need it to try to compensate for the problems caused by over-driving the silicon for the SATA-III portion. But, an oversight with the newer revision motherboard. The problem did tend to occur in the early morning hours on the weekend, when not only is there a lot of daily disk activity, but there is also a lot of weekly disk activity, etc. Oh well.)
So, after upgrading the zpool, and reinstalling the boot block/code. I then rebooted the system again. I had already identified the zfs filesystems where I had 'compression=on', so had written a script to change all these to 'compression=lz4'. Which I now ran.
And, then I turned my attention to doing dbox.

Hopefully, this isn't a trend... but rather a strange problem that has now been treated (through the use of Muro 128 at night for the last few weeks and to taper off over the next couple...)

Wonder if there's enough time to get a new pair of glasses online cheap, before my upcoming trip (Narcolepsy Network Conference). And, to use up the remainder of my limited use FSA, which is kind of surprising to have last this long this year. Probably because of the unstable nature of my eyeglass prescription this year, I didn't get what I really wanted in a second pair of glasses this year. Maybe I'll finally get around to it next year....
Just as long as I can see the best that I can for the 50th anniversary of Doctor Who!
This weekends project was to update the skins to 5.x.
From the early 0.8x days of this blog, I had settled on a customized version of the custom skin. Recustomizing it each upgrade was annoying, until I found that I could make my own version of it and it would likely work. Though if there were (bug/security) fixes, it was easier to find out what those were and apply them to my version of the skin.
So, I created an LKC skin for the blog.
This worked surprisingly well, when I upgraded from 4.1.7 to 5.0.5 last weekend. In that I made no changes to any of its files, and it pretty much worked. There was some breakage which I later found was due to some reorganization in global css files due to global css (which I could've fixed by copying the global css files from 4.1.7 down to the skin directory level. But, it was easy enough to fix up some html tags in
index.main.php and "free html widgets". Plus I also removed some other widgets in the process, such as no more Flash Tag Cloud, or the flash twitter widgets (which I guess were broken since the twimg.com incident anyways, and doesn't seem to be available anymore).
This single instance of b2evolution, is also home two a couple other sites now (I used run separate instances, of the heavily customized nature of the early days for this blog, but the work in maintaining them all was a pain, and since they're all with the same hosting provider...going multidomain seemed the better way to go, though it has its challenges.
So after I updated 'LKC', all the code I had changed to get around the css problem needed to be changed back now that it wasn't a problem anymore. Well, it didn't have to be, but the HTML tags I used had been deprecated for quite some time, so it was kind of strange using them again to make things work for a while.
The I turned to the other sites, first is the photoblog site, which is using the included photoblog theme directly...with minor tweaks. I should probably split that off someday. But, only one file changed between 4.1.7 and 5.0.5, though I had pulled up some files from global into it to make some customizations. Though in 5, there's back office means to do the same thing...so to update this skin, I removed those specific customizations and moved the information into the back office. In fact, I'm not sure what if anything I've changed to it for its current appearance. Though there's some things I think could be done better if I had some time to put into it.
Then the other was using 'emerald', which was a 3rdparty skin. I mainly wanted something simple with 3 columns, with the level of customizations that fit my desires at the time. It was originally released for 2.4, but somebody else had updated it for 3.0 or newer. And, while it suffered from similar problems to other old skins that I could work around, I had a desire to make it consistent with 5.x themes. I had checked the forums, and there was one post of somebody who was working on updating their theme which had been based on this to fit 5.x. Though looking at their site, I wouldn't have know it was emerald .... and, there were any details on what he had done to making 5.x...or not sure if it was the issues that I was having.
So, I looked around at other 3 column themes to try. Soon, I decided that I would just use 'evopress', an included theme...and make customizations to it. So I copied it into a different directory and changed
_skin.class.php appropriately. And, then made some code changes, namely to
Now its late, and I have road trip to UNMC tomorrow....
Well, I got the upgrade from b2evolution 4.1.7 to 5.0.5 done today. There had been a few failed starts over the previous few weekends.
I had a plan on how I was going to do it, which was aided the 3 way diffs between my site, the b2evolution-4.1.7 code and the b2evolution-5.0.5 code. Later I did a diff of just my site and the b2evolution-4.1.7 code.
Since it was easier to spot what I had done this way, since pretty much everything in the 5.0.5 side was changed... making it hard for the tool to show where my site differs from the 4.1.7 code.
I did that there was some cruft from previous updates or files that weren't part of the diffs. Perhaps diffs only contained files that had changed between point releases, and omitted files that were new. Or diffs and releases were different on how they handled reorgs. Hmm....
Anyways...in the end it was find what customizations I had done, and apply those changes to the 5.0.5 code. Though I later found that there is now a place in the 5.0.5 code to insert custom data instead of editing the _html_header.inc.php and _body_footer.inc.php. Wonder if I'll go back and try that. Currently, that only affects one skin. The other skins I use, I made copies of so I'll may need to see if they need to be brought up to 5.x. One of the custom skins is based on one that comes with b2evolution, but I've changed it so heavily that it was kind of painful patching it as part of every upgrade....until I went with making it separate. Don't know why I didn't do that with all of them. Though the other skin I may or may not need to update is not one that comes with b2evolution, so it may or may not have been updated for 5.x. Especially, since the current is for 3.x.
Kind of frustrating thing with b2evolution....the lack of current 3rdparty skins and plugins for it.
Well, not yet...though I've been having trouble seeing more and more the last few weeks. And, there was a evidentally measurable change in the right eye.
But, today's exam was to see if I might have Glaucoma. Had gotten a retina imaging test back in February, did another today and things look the same, so probably not Glaucoma. Though today my field of vision testing was bad all over, like a more general loss of vision.
Since the shape of my cornea has changed over the last 3 exams, he suspects its changed again though the test wasn't during the initial testing of the appointment. It got done before I left.
Gonna try some eye drops for 2-3 weeks to see if things get better, worse or not.
Earlier this month, I took a little staycation (during which I did my "Narcolepsy: Not Alone" photo)...didn't get all the things that I wanted done, and watched even less TV than I do normally. During this time, I didn't check my 'work' email accounts (including the gmail account that I had associated with my work smartphone, which I haven't had one for a long time since I opted to downgrade to a basic prepaid phone on my own dime.)
When I returned to work on August 12 and started catching up on my email, I found a bunch of emails from my cousin June. My grandfather likely passed away due to sudden cardiac arrest Friday night (August 9th, 2013). He wasn't discovered until Saturday morning, slumped over in his walker, when my grandparent's helper showed up. He was 93 (June 12).
Guess there were other emails to my other gmail account (from my parents), but that account has become overrun by emails from places I've shopped and many discussion groups. Need to make more filters to clean things up.
Anyways, I was in shock. I was quite close to him, he's in many of my early childhood memories. Perhaps because he was the other tall person, we shared some common interests (namely photography and home stereo) growing up and he facilitated my growing interests and lead me in how passionate I am in those areas. Which has led me to being equally so in many of the other areas that I've gotten into both personally and professionally. I'll probably never have the a home stereo system like the system that drew my attention in Taiwan, Photography continues to be a part of my life despite it becoming harder and harder to do. It was how my tremor was making it difficult to enjoy my Photography hobby that had led to the diagnosis of Essential Tremor, not that it was making it hard to do precise mouse clicks at work. I've never really been a big GUI person....and as my Tremor progresses, its not likely to change....
While I hadn't seen him since 2010 when I visited him for his 90th birthday, which as it happened was also during an email move at work. In my mind there was that there ought to be a family reunion in 2015 for my grandparents 75th wedding anniversary (and 95th birthday), where we haven't had much of a family reunion since my aunt Clara had passed (in 2004). There was also the thought of a reunion in 2020 for his 100th birthday.
That makes 2000 our last family reunion (and my first cruise), which was for my grandparents' 60th wedding anniversary and my grandfather's 80th. We did try to have a reunion in 2005 (my third, and final , cruise)...but no Leo, Cathy or Charissa...and my grandparents eventually backed out. They haven't been into air travel for some time, and we weren't able to find a cruise around Los Angeles. We settled on one started/ended in San Diego with arranged car service to transport them to and from the port. Still it was a good cruise, even though I was flying back to so that I could be laid off from my previous job on Christmas Eve.
Then some guilt crept in as I then became angry that I didn't know about his death sooner. Along with trying to figure out bereavement leave policies and whether I could get an airplane ticket, etc. to attend his funeral on August 20th. I managed to mostly keep it together and push through the rest of the day at work. When I finally got home, I was starving and much sadness came in bursts.
Eventually, I call my parents to find out what travel plans they had to give me an idea of what plans I should make for my trip. And, then it was to see about finding an airplane ticket....I had been combing sites earlier looking for tickets for other upcoming trips, like NN Conference in October and Chicago Tardis in November. Which I probably should pull the trigger on purchasing soon, but there's a staging of when I purchase such things to manage the hit on my credit cards....
After some playing around, I find a combination of flying in the morning of August 20th and flying back on the 21st for $440...with ATL being around $470 and ORD being around $415. But, its only for a specific flight out of MHK and a specific flight back to MHK. Moving to either side, practically doubles it.
Also, I had to leave the booking with no seats selected, because the only seats it says are available are preferred or extra room seats, so two levels of extra charges. So, I left it to see what it would do when it tickets, which isn't until the next morning. It has seat assignments for MHK to DFW and DFW to MHK, but neither of the LAX flights have seats.
Should probably get to buying ATL ticket soon (now), though was considering buying ORD first given the notes of only a few seats left at the lowest price.
On my FreeBSD system, my
apache webserver would get angry whenever I update the
php & extensions ports. Requiring a bunch of other operations after the '
Since I've been playing around with CFEngine 3, I had started to add to my "
bundle agent apache", to do more than just promise config files current, process running, reloads, etc.
So, one of the first problems I had run into on FreeBSD, is that there are certain extensions that need to be in order in '
/usr/local/etc/php/extension.ini'. Which is solved by using
Well, fortunately when this script is run it results in a backup file of '
extensions.ini.old' which is the same age or newer than '
CFEngine3 can take care of it this way:
g.apache is "
apache22" currently on FreeBSD, and "
apache2" on Ubuntu. Someday it might become "
apache24" on FreeBSD.
Since I did FreeBSD first, and I'm still working on getting my one of 4 (or less) Ubuntu rolled in, I have:
g.rc_d as "
g.lrc_d as "
/usr/local/etc/rc.d" for FreeBSD. They are both set to "
/etc/init.d" for Ubuntu. I also have a
g.init_d for Ubuntu, but not FreeBSD. Not sure which I'll use where....I suppose if its an OS specific case,
g.init_d would get used and if its not...then which ever one is the correct one for FreeBSD will get used.

A couple months ago I asked if mosh could be made to work if the mosh-server IP changes when roaming between networks.
Years ago, I used to have routers that did 'loopback', but haven't had ones capable of it for sometime...or so I thought. Though I hadn't really had a major need for it. Except perhaps for
mosh, MObile SHell, is an ssh replacement that supports roaming and intermittent connectivity. Since I do my IRC using irssi in screen, running all the time on a server at home. This makes staying connected to IRC on my laptop much nicer. I can close my laptop, and later open it and it'll still be connected to my screen session.
The problem was when I came home, I'd be unable to recover the connection correctly and the client goes into an unrecoverable state, so that even if I later use my laptop on an outside network the mosh session won't resume.
But, today I opened my laptop (and I just realized that I didn't do what I had intended to do) and I just minimized the window out the of the way...even though it probably wouldn't recover on Monday at work. But, the dock icon showed that something wanted my attention....probably mosh-client giving up? No. Well, my nick had come up a couple of times yesterday, but it shouldn't have known that....but not really thinking, I switch to the channel. And, it does. I switch around and its working. Wait...it shouldn't be though!
So what changed? I do a tcpdump and see that it is connecting to my WAN IP and getting responses from my WAN IP....'loopback' never worked for me though....
Perhaps its 'loopback' of port forwards that has never worked....
I had moved irssi from box to dbox a while back. The router has two port forwards set related to this to box, a single port TCP forward and port range UDP forward.
But, because my other router is running stock firmware, it has a limited number of port forwards...so as I was migrating services to cbox (and using nginx to reverse proxy web services on other systems on my home network, where those that use a webserver are using apache, including local services...such as cacti on cbox and nagios on dbox), I decided that I would just make cbox the DMZ host...start running host based firewalls at home, especially on this host (it also uses an IP alias...kind of like how we do hosts behind the BigIP at work )
So that means no port forward(s) for my dd-wrt router for WAN to dbox....so I guess the NAT allows 'loopback'ng in this case.
Wonder if the same applies to my other router.
The only problem this causes is that I had plans to replace routers. I actually have a new router to replace the current stock router....though I haven't got anything that really needs to speed upgrade to 802.11ac yet in the room where I using wireless bridging. I also had plans to replace my dd-wrt router, which had started getting unreliable which they seem to do after a while....though it seems to have helped after I deleted old traffic data....
There are Unix servers at work that have uptimes in the >1000 days, there are even servers with updates in the >2000 days, in fact there are servers that have now exceeded 2500 days (I'm looking at one with 2562+ days.)
On one hand there are SAs that see this as a badge of honor or something to have had a system stay up this long. OTOH, its a system of great dread.
A while back this system was having problems....its Solaris and somebody had filled up /tmp....fortunately, I was able to clean things up and recover before another SA resorted to hard rebooting it.
The problem with these long running servers, especially in a ever changing, multi-admin shop, is that you can't be sure that the system will come back up correctly after a reboot.
We've lost a few systems at work due to a reboot. Some significant ones as simple as replacing a root disks under vxvm and forgetting to update the sun partition table, or a zpool upgrade and forgetting to reinstall the boot. To more significant ones, where a former SA had temporarily changed the purpose of an existing system all by command line and running out of /tmp...so that after its been up for 3+ years and he's been gone over a year....patching and rebooting makes it disappear.... the hardware that the system was supposed to be on needed repair, but he had never gotten around to it.
It'll be interesting to see what happens should the system ever get rebooted.
So, what brought this post one?
