VLANs & FreeBSD 9.0/Jails

The backstory is that I've been working in a primarily Sun shop, and one of the things we've been doing is running Solaris 10 on large boxes, such as T2000's, T5120's, M4000's and cutting them up with Solaris zones/containers with the global native into a management vlan and tagging appropriate vlans for the zones, and the zones have their own default route specification so all has been great.

ipf on the global so the zones can't tamper with their own firewalls, and on some of the 'zone' servers using:

/usr/sbin/ndd -set /dev/ip ip_restrict_interzone_loopback 1

The zones remain isolated from each other. Or it avoids problems of short circuiting (asymetric routing + wrong IP)....because some of the zones are behind the F5.

For years, we've tossed around the idea of introducing FreeBSD into our datacenter, and finally one of our customers decided that while they really like the containers/zones and ZFS, the cost of replacing their aging Sun server would be better done by replacing it with a FreeBSD server. While they own the hardware, and it resides at their facility...we provide the system administration support. But, this opened the door to having FreeBSD on our work site. I was in the process of replacing my aging Sun Ultra 20 with an Optiplex 990...which originally I was looking at install Ubuntu on, but instead I went with FreeBSD 9.0 (though the effort in getting the Desktop working on it, and recreating my Sun desktop/work environment on it...made me question if that was really the right way to go. But, I got it working.) And, it helps me try some of the things before doing them on the customer's server (which is headless in a closet [well, they have a monitor & keyboard for console access], so all the desktop stuff was for my benefit...it paved the way to me getting a working FreeBSD desktop at home &#59;D .... though I may end up with a different system for my main desktop at home and have the FreeBSD machine go headless with my other FreeBSD servers....unless there's some way to easily share between the two....switching doesn't qualify.)

So, in needing to deploy some new internal services (such as monitoring) and not really wanting to go through the major process of find all the bits and pieces and creating packages under our CM system for Solaris. Its quite the pain building each and every perl module as separate CM packages, instead of having some system that automatically builds and installs (or makes packages) for you...ala ports or CPAN. I've done package install requests that start out as install one package, and end up building 100 or so packages instead.

I had contemplated sneaking Ubuntu in since I run the same monitoring servers on an Ubuntu server at home, but the work to incorporate Ubuntu into our configuration management infrastructure got sidelined by FreeBSD. And, there's no decision on whether Ubuntu will come into play (though the high cost of RedHat licenses to just get patches...for systems that are rarely patched....is making Ubuntu look attractive.)

Anyways things led to me starting work on pxe boot installing Proliant DL380s with FreeBSD 9.0 and creating 'jail' servers to work like our 'zone' servers.

Cloning interfaces to do VLANs was simple ....

Orac is looking strangely bare, with Zen taking over.

For a long time, I've been running a 6 drive RAID 10 array of Hitachi 5K3000 2TB drives in Orac for backuppc. This configuration got me at 5.4TB array, and somewhat better performance than when I tried a RAID6 configuration. But, eventually, I kept running out of space and the price of harddrives went up so expanding the array over time didn't happen as I had hoped. Being RAID10, the options were other concat another array, either 2 in RAID1 or 4 in RAID10 or 4 as 2 RAID1....using volume manager. Or maybe see if RAID10 would deal with having all 6 drives upgraded to 3TB, though hadn't considered the transition of 512 to 4k and how it would cope with that.

Though I did, eventually find out when I upgraded a 1.5TB RAID1 set to become a 2TB RAID1 set....going from ST31500341AS to ST2000DL003, where I contributed my experience here: http://askubuntu.com/questions/141669/creating-properly-aligned-partitions-on-a-replacement-disk/ Though it first started because one of the ST31500341AS drives had failed.

Before the failure of one of the 1.5TB drives in the above mentioned RAID1 set, I had 4 ST31500341AS in a RAID5 on old-Zen. It had been done in under RR622, under Windows, and NTFS partitions, etc. I had tried copying the data at various times, not really having anywhere that would hold the data elsewhere...but wanting to get it over to FreeBSD for recovery. While I got the rr622 driver working, and it saw that I had a single array (rather than the native driver that would see the 4 individual disks.) I couldn't get access to the data. Though it had worked when I was previously playing around with Xen (had tried copying it then....to a 2 1TB RAID0 set, but then one of the 1TB drives died....so I lost the copy, I had then replaced it with a 2TB RAID1 set....using an ST2000DL003 and an ST2000DM003, the DL being a 5900RPM drive and having a 5 year warranty...while the DM drive is a 7200RPM drive, but with only a 1 year warranty. And, turns out the 1 year is generous.

At work, I had built my FreeBSD desktop using a pair of the ST1000DM003 drives...and 3 drive failures later....it is now a pair of ST2000DL003 drives. Yeah...I was having trouble with the array, and apparently using XFS was a mistake too...because I thought it was recovering, but instead it was slowly eating the data. When I had nuked the RR622 RAID5 array, and had switched to using it as JBOD and create a RAIDZ set under FreeBSD...I found that there was nothing to copy back from the RAID1 array. D'Oh! >:XX

Though I had also copied the Microsoft WindowsImageBackup files, to see if I could mount the VHD file under VirtualBox to help in recovery. I largely had the data in bits and pieces elsewhere, it was the environment I was wanting to recreate...and Oops!Backup didn't back up that part anyways (the data I was mainly trying to migrate). The image mounted, and I could see it...but soon after Windows would try to fix it and then it would disappear....kind of like what it did on February 15th to make the original Zen go away. No idea what kind of disk rotting the Intel Matrix RAID had been doing, when it had to initialize the array again every time after a Windows crash. I've had Ubuntu crashes, but the RAID arrays remained stable...usually. While Windows & Intel RST....it was pretty much every time. I'm sure it was slowly corrupting things overtime to where things wouldn't recover, though it choose to do that after an automatic reboot for Windows updates...and the day before I left for my first Gallifrey One made things even more annoying.

Anyway with another 1.5TB drive freed up, I contemplated adding it to the RAIDZ I had made of the 4 1.5TB drives, keeping it as a hot spare, or just use it by itself -- living dangerously. I ended up with the latter for some temporary data. Because in my mind I was starting to lean to what happened next.

Getting nxserver working on FreeBSD

One of the nagging issues was getting nxserver working on my FreeBSD system. The procedure should be to install 'net/nxserver' and 'net/freenx', but the problem is that 'net/nxserver' can't be built on a 64-bit system.

So, taking a page from 32bit Wine on FreeBSD/amd64, I built 'net/nxserver' in my /compat/i386 chroot, with "make package clean".

I then installed the package into my 64-bit system, so that I could build and install freenx.

Of course that didn't quite work....had to overwrite the nxserver binaries with various shell scripts to call the /compat/i386 versions.

IE:

/usr/local/NX/bin/nxagent

Shell

#!/bin/sh
#NXAGENT - Version 2.1.0
export LD_32_LIBRARY_PATH=/compat/i386/usr/local/NX/lib:/compat/i386/lib:/compat/i386/usr/lib:/compat/i386/usr/local/lib
exec /compat/i386/usr/local/NX/bin/nxagent "$@"

/usr/local/NX/bin/nxdesktop

Shell

#!/bin/sh
export LD_32_LIBRARY_PATH=/compat/i386/usr/local/NX/lib:/compat/i386/lib:/compat/i386/usr/lib:/compat/i386/usr/local/lib
exec /compat/i386/usr/local/NX/bin/nxdesktop "$@"

l, since nxloadconfig does a "string $PATH_BIN/nxagent" to find out what version you have. So, I copied the string into the file.

And, then after lots and lots of troubleshooting, I eventually found the last hang up....

Shell

Though maybe the line above was meant to be "$ENABLE_2_0_0_BACKEND" = "1" and eliminating the EXPERIMENTAL rule. :??:

Anyways, it works.... :cool:

...except that logging into another session of myself was a mess on the tiny screen of my laptop....its not dual 1920x1080 like my main desktop. And, logging out messed up my active desktop session. It apparently killed gvfs, so I couldn't ls my home dir anymore. And, then I killed to much and had to reboot. :##

Meanwhile...still trying to workout how to get nfsclient to take place after vboxheadless starts, so it can mount NFS filesystems from my VM. :hmm:

Finally upgraded b2evolution

From 4.1.3 to 4.1.5b.

Maybe I'm getting better at these small patches, because it didn't seem as hard to do. Or perhaps because I was able to figure out my own customizations and back patch them into the patch or that I'm getting better at where I put my customizations....

Plus one of them matched one of the patches....resulting in just shifts in line spacing and newer comments. &#59;D

Though was getting worried considering I put off applying 4.1.4 so long that 4.1.5 came out, and became 4.1.5b. Though I would have to do them separately, but then it occurred to me that if 4.1.5 changes anything in 4.1.4 it'll overwrite those files. So, all I had to do was three-way diff and figure out what from mine goes into 4.1.5b and lay that down on top.

Though I did see that I have files that don't exist in either 4.1.3 or 4.1.5b...probably left overs from much earlier 4.x versions. Though was surprised to see that a plugin was newer in 4.1.3 than in my version. Not sure how that got overlooked until now.

There's other plugins that need updating, but I'll do that later....

It's the end... but the moment has been prepared for. Sort of...

And, it almost didn't regenerate in time....

First it seems my first TiVo HD is nearing its end. With it constantly locking up, and other problems that started ... but the moment had been prepared for.... With the Premiere Elite that I had gotten recently.... Just need to work on watching or moving the shows that are in it. Then it would free up the My DVR Expander to add to the Premiere Elite. And, since I have lifetime service for it...I suppose I would look into a Weaknees upgrade for it. But, I'll stay with eventually returning the cable cards for it.

And, now the end of my Samsung HLN4365W1X seems to have come. It came to me on May 30th, 2004, and it started having its latest issue on Sep 21st, 2012. Guess just over 8 years. I kind of knew it wasn't going to last forever. Since, it had consumables (bulbs) and mechanical components (cooling fans & color wheel).... and eventually I would like to upgrade.

I had replaced the bulb a couple of times....getting about 3.5 years.... Which is kind of sad, since I had gotten the 3 year extended warranty, because of the stories of premature bulb failures in this model. Now, its hard to tell what's wrong...the internet is kind of mixed on matching my symptoms with what might be wrong. But, I suspect the Ballast. It'll eventually come up, but it makes a lot of noise...and then it can't be turned off. It did settle down on Saturday so I could watch my Doctor Who...so I held off a bit on pulling the trigger to replace it, though I probably shouldn't have. I did some research on whether this was something I could fix myself, but in the end decided that it wasn't worth the hassle given the price of what a new TV is and how much sooner I'd get it. Just means, the other thing I was wanting to get this year will have to wait another year. Though its starting to look a lot like Apple isn't going to come out with anything new this year anyways.

I kind of had envisioned someday getting an LED TV in 1080p, and 50" that fits into my stand....perhaps even 3D.

The stand is just wide enough to accomodate a 50" providing the bezel isn't too wide. But, when that DLP came out, I wasn't ready to make that kind of leap. And, until recently, LCD/LED displays are either like 46/47" or 55"....the 50" size seemed to only be Plasmas.

And, I had considered whether it would be so bad to get a Plasma....though I think I want to not worry about when my next display is going to be for a while. So, LED/LCD TV is probably what I'll have to stay with.

Wonder if I can get something delivered next Saturday....

ulkc has 8GB of memory

So, a while back I read that it would be possible to upgrade a number of older computers from spec'd maximum to a bit more.

Officially, the maximum supported memory of the Lenovo 3000 V200 (ulkc) is 4GB... My other laptop also supports a maximum of 4GB, but I suspect that between them, I should be able to upgrade one or both to 8GB. Though I prefer to have it work in this one, since I use this one more.

So, a while back I had a newegg coupon to get laptop memory, so I got a pair of the SO-DIMMs. But, then I set them aside....and forgot about them.

More recently, I picked up a new battery for this laptop...and had it in the bedroom to run down and see how much life I would get. Online they sell aftermarket batteries for 4800mAH and 5200mAH. Though it turns out the original battery was 5200mAH.... So, that's what I have....anyways it works. And, I let the laptop rundown. So, I was going to try the memory swap after that. Though that was a few days ago....

NetBackup 7.5 on FreeBSD 9.0

There's a FreeBSD 6.x client for NetBackup, but when we upgraded to NetBackup 7.5...client installs stopped working, after ignoring the problem for a while (since the 7.0 client installs were working) until I had set up a new FreeBSD 9.0 server.

What I did was

  1. Install 'misc/compat6x' and 'java/openjdk6'
  2. Obtain 'fakegetfsstat.c' - and build it on a 32-bit FreeBSD host (I used the '/compat/i386' environment from building "32bit Wine on FreeBSD/amd64") and put it in '/usr/local/etc' -- there's probably a better place, but :lalala:
  3. check that '/usr/openv/netbackup/client/INTEL/FreeBSD6.0/client_config' has "compat_dir" set to '/usr/local/lib32/compat'
  4. Install NBU Client -- It still won't find java, so perform the steps it says using '/usr/local/bin/java'
  5. Edit '/usr/local/etc/netbackup'
  6. Shell

Finally got a new shower head....

Ever since my first Chicago TARDIS....I've been wanting to get a new shower head at home...a dual head one...like the Speakman's that were in the hotel rooms there.

But, I've also wanted to get a handled shower.... But, then I impulsively got a newer shower shelf that wouldn't work on my current shower arm...so having to replace the shower arm, would mean time to get a new shower head... and so, after much putting it off, but constantly researching the subject. I then spotted this shower head.

...and decided to purchase it. Since it also solved the idea of being able to shower late at night without turning the light on (still haven't gotten around to figuring out to separating the bathroom light from the bathroom fan.)

It took a few weeks after I got to finally to do it, but one Sunday morning I after showering that I decided to tackle the project. In turned out to be quite an effort to do, so I christened the shower by showering off the sweat I had worked up in installing it.

First problem I ran into was my shower shelves I had weren't designed to accommodate a shower hose....so I had to get a new one....eventually.

Transit Service comes to Manhattan, KS

This was originally going to be a longer, and possibly angrier blog post about transit service finally coming to Manhattan, KS.

But, it needs to come first before another post that I've been writing in my head...so I need to get something out.

The background, is that back when I lived in Medicine Hat, which at the time was about a 35k population...though it has its cyclic population factors....the main being summer army training activities, and the influx of british soldiers. But, it was nice small city with a town like feel...and it had a wonderful bus system....5.5 routes. Well...4 of the routes were really 2, two buses on the routes...and downtown terminal crossings. Then there was a route that ran between the two malls, so didn't ever go to the downtown terminal. And, a part-time route that went to the community by the airport. They were probably 50k population in real numbers...but there's also a large chunk of the population that give their primary residence as being across the border where auto insurance is cheap...being a no-fault state.

One of the ideas that brought me to Manhattan, KS was that its kind of like Medicine Hat. Well...it does have the huge population swing....when the 23k+ students are here and then aren't. And, it was an under 50k population city. But, the big surprise was there is no bus service here....which is kind of problem since I don't drive. Though it did have much better walk-ability than where I was before in Columbus, Ohio.

Anyways...finally being over 50k in the 2010 census....a bus service could finally be created. And, there had been a few proposals on what it would take form of when it started. Eventually, the paratransit service (ATA Bus) expanded into doing fixed route public transit service that has finally arrived. ATA used to stand for "Aging Transportation Agency", but now it stands for "Area Transportation Agency".

The service was started with funding from federal, state, county and private funds. There was originally a proposal to seek city funding, but the city rejected it. So, the service went ahead with private funds....which causes the first problem with the fixed route service in Manhattan, KS.

City wouldn't allow bus stop signs to be put up. So, where the stops are exactly...is pretty much only known to the drivers. And, in some cases...it is only known to the specific driver. There have been numerous times where I was missed or nearly missed, because a driver stopped (or didn't stop) in a different place than expected.

There are like 3 places where the bus driver might stop in the College Ave United Methodist Church parking lot.... two are in front of the church, but one is where the driver hairpins entering the parking lot and pauses only long enough to quickly open and close the doors at the street entrance. And, doesn't really look around to see if anybody is standing running from the entrance of the church screaming because of this.

There are also at least 2 places for the stop in the Ace Hardware parking lot....usually its kind of in front of "Alex's Affordable Eyewear"...but once when it was running late....it just came in straight off Hosteller Dr and went straight to the exit to Bluemont Ave, and then just quickly opened and closed the doors for a split second and then took off without looking around.

Where the bus stops are shouldn't be a game where only the drivers know where they are (and they can move them when its suites them) and penalize anybody that didn't guess right.

Which brings us to the second problem with the ATA Bus service.

While running late could be understood....providing the drivers still stopped in their efforts to get back on schedule, instead of not picking up people waiting for the bus. Even the people that have ridden before, so know where the stops should be.

But, there's also the problem that if the bus is running fast...they don't care. There have been numerous times where I've been waiting at the CAUMC stop...and having an Atomic sync'd watch...know that I was there before the scheduled time....only to have no bus ever show up, because they were probably early. Except to make things worse, if you call to complain...they'll claim that the bus was there exactly on time, ignoring if you tell them that you've been waiting there 5 minutes before that time. Or that the stops have no shelter from the rain or the sun...and its 102 or hotter.

Otherwise...the service has been great, and I hope it gets better.
