Re: [Discuss] AT eliminating copper phone lines

[Joe Polcari]

Magic Jack works great. I still have my phone number of 20+ years, and it’s 
cheap.

Subject:  [Discuss] AT eliminating copper phone lines


AT is finally eliminating its copper phone lines in my area. (I
recall Tom Metro starting a BLU discussion when Verizon did the same
thing in 2013.)

The alternatives for a home landline now seem to be:

1. Let AT replace my copper with a fiber optic line. (Con: Expensive
service, $100/month.)

2. Add phone service to my existing Verizon FIOS Internet plan. (Con:
I lose my phone number of 25 years.)

3. Switch to Vonage. (Con: Might not work with an alarm system.)

4. Eliminate the landline. (Con: Screws the alarm system, and
cellphone voice quality is too poor for my damaged hearing.)

Am I missing any better options?

i run a perl cgi script on www/moylan.us as well as on my

fest the script ran fine both places, but in the afternoon
it failed at moylan.us, though it continued fine on my local
host.  my web hosting service was migrating to a different
server over the lunch hour.

the error message i receive is:

 Can't call method "prepare" on an undefined value at
 /home/moylan/ulmmoy/prl/sub/USR/USR.pm line 777.

the code around there is:

 775  # get all current logins
 776$stm = "select * from log";
 777$sh0 = $dh0->prepare ($stm);
 778$sh0->execute ();

i had the same problem two years ago, but on my home
machine, not moylan.us where the script ran fine.  as best i
can recall, the solution involved disabling selinux --
though i'm not certain.  however, i checked and the remote
server already has selinux disabled.

any thoughts as to what could be going on?

Updates can take quite a long time to be disseminated, and also some DNS 
servers are just flat out terrible.
Are you using your ISP's DNS ?  Is it comcast?
A few years ago I ditched comcast DNS for Google public DNS servers. I 
configure this in the router. IP v4 addresses are 8.8.8.8 and 8.8.4.4. 
The IP v6 addresses are at 
https://developers.google.com/speed/public-dns/docs/using#important_before_you_start
This made a very noticeable difference in latency 

Also at that point comcast was doing wacky browser jacking that really 
infuriated me. I believe this was on domains that were not found. I don't 
imagine they are still doing the browser jacking ... at least I hope not! If 
they are though it is a clear sign you are using their dns. 
I believe I could not get a google search .. instead it would return a comcast 
search if the domain was not found.

Agreed. LOL I remember watching a YouTube video explaining how to bypass the

They could have Google'd/Ducked/Searx'd it.

https://www.youtube.com/results?search_query=get+around+the+iphone+passcode

Quantum computers are coming too, which would break all the locks ever
-- as far as I understand. Encryption is literally an arms race of "brute
force" computing power against mathematical obstacles, and protection
against attacks is limited by access to said computing power and access to,
as you say, physical security. Stronger shields, better weapons to break the
shields, stronger shields, better... In the end, the little people will be
left with the least protection of both kinds because they are always falling
behind. Warning: Thinking about it too much will induce burn-out. :/

Re: [Discuss] free email less intrusive than google

[Joe Polcari]

And if everyone had that attitude, this politically correct crap wouldn’t exist 
… but nooo.
But who am I to judge - if it pisses you off, I’m sorry, I didn’t mean anything 
by it, I just won’t say it anymore to you, I didn’t know it meant anything 
other what I intended but apparently my intentions don’t count.
The politically correct stuff comes from someone trying to suppress my speech 
because it ‘may’ insult someone/anyone.
Like the holiday is named Christmas, but you can’t say it when wishing someone 
a good holiday.
Or am I missing the point?

You're assuming changing the voltage changes nothing else, if you try to
apply Ohm's law directly.  Many other things change when you change the
supply voltage of a semiconductor/PCB.

Among them:
Switching thresholds
Edge rates
Leakage currents
Capacitance of most of your capacitors

Look deeper: FreeNAS runs from images. When you update FreeNAS you 
download a new image and that image is added to the boot loader.

Installing FreeNAS to a fixed drive entails using another host to 
install the image to the drive and then moving the drive to the FreeNAS 
host. Upgrades are done the same way: remove the drive, install a new 
image, return it. Pain in the behind and a waste of a perfectly good SSD 
that would be better used for ZIL.

One way to look at the difference between FreeNAS and PC-BSD is Android 
vs. Ubuntu. Similar idea: FreeNAS and PC-BSD share the same kernel and 
user space but in practice the former is a file service appliance while 
the latter is a full-on computing system.

NB for Rohan: FreeNAS has a recommended minimum of 8GB RAM. PC-BSD has a 
more modest 1GB minimum with 2-4GB recommended. If the system supports 
two DDR2 sticks then I strongly recommend upgrading to 4GB at the least 
regardless of what you run on it.

TrueOS. It's a server-focused variant of PC-BSD which is a FreeBSD
derivative intended to be easy to deploy, use and maintain.

 Also, any other suggestions of how to go about this are welcome.

TrueOS. ZFS with mirrored storage disks. SMB or rsync/Unison or whatever
gets your data onto the server. zfs send to copy snapshots to removable
media for longer-term archival storage.

You could use CentOS with ZFS on Linux but you would be saddled with a lot
of bloat that you don't want on a small server.

Subject: Re: [Discuss] raid controller drivers

I agree with Richard that it's easier to put grub and kernels on a non-raid
disk. You can also use that disk to save details of the configuration. If
you want speed consider an ssd for boot. It only uses a slice of the drive,
and you'd avoid all these problems with initrd  - and also perhaps grub as
well.   I had a system set up to boot from a software raid array but now
I'm much happier booting that system from SSD. I also save some
configuration data useful for recovery on the ssd.

I think there may be a script someplace to convert all disk settings to use
UUIDs.

I believe that some hardware raid cards are configured on system boot with
a settings interface you could enter with a correctly timed key stroke like
bios settings. ... Of course much has changed with boot over the last
several years. At least with some controllers, the disks are available
separately, but the single joined disk is not available until you have
entered the setup and configured the disks as a raid volume.  You could
also just use mdraid to create the array from the disks, which will be
about the same if the raid controller is a firmware controller without a
dedicated processor and cache.

I seem to remember that another gotcha is that grub might need to read from
the controller if the boot volume is on the array. Grub can read from
mdraid and lvm but at one point you had to set those modules to load, or be
dropped to a prompt and load them yourself. Maybe it's now default,
detected,... configured when you install the os.. I'm not sure... and don't
know if you'd run into the same issue with hardware raid if you can
configure the controller to present the array as a single sas or sata disk.

One downside of raid is that whenever you read or write anything all the
disks spin up. That generates more heat than reading from a single disk. I
had two disc logic boards die at the same time because a fan on the
backplane failed.   I was using raid5 and so had to recover one of the
discs and replace the second one. I was able to replace the logic board but
it had to be a board from a very close serial number match... model match
was not good enough. Ugh! I finally got the array back up... I used the
lowest $/gb sata disks I could find. Good for you for using SAS disks !
Even so If you leave this system running you might want to monitor the disk
temperature.

 In your worst case, you could hardwire one in the North and South corners
 of the basement, for example.   Or pop a hole up to the first floor
 in a couple spots.

 Remember the donut shaped energy field off each antenna, and point
 appropriately.

 I use hardwired where I can, off the wifi router.   The rest of the
 family, with ipads and smartphones need wireless.

 Even with no wires at all, you can do (less effective, but...) at least
 I think you can do radio to radio wifi routers.  Called mesh?   Never
 needed to do myself.

 

 I've been told, but not positive, that the radio sections of wifi routers
 seem to crap out over time, especially consumer grade products.
 Maybe just salesman folklore.

 There used to be a Linksys power pack type thing that boosted the
 RF signal, up to IETF RF signal limits.   No opinion there.  I'd guess
 all manufacturers tend to build today up to maximum power limits?

 And there are a plethora of directional antennas.  I found them
 cost prohibitive, and too much trouble.

 Apologies to Lewis Carroll. I'm afraid the following doesn't scan as
 well as his version:

The time has come, my router said, to talk of many things.
Of 802.11 ac and n and g and b,
And why Cisco updates without permission.
And the safety of ASUS settings.

:-)

 It's long past time for me to replace my 802.11 g router with something
 more recent.  But I have a few constraints that make it tricky to select
 the right router. So my question is, do any of you have experience with
 the ASUS RT-N66U or any other router that fits the constraints I
 describe below?  While I'm interested in recommendations of what's
 worked well for you, I'd also appreciate warnings of what to stay away
 from. advTHANKSance for your help.

 My constraints are:

 1. COVERAGE:

The construction of the house the router will be installed in is
problematic WRT getting signals through.  It was built before
drywall was in common use in the U.S.  But rather than using wood
lath, the plaster is held in place by lath.  But it's not
traditional wood lath.  It's WIRE LATH.  Also, the heating system is
forced hot air, which means that there's SHEET-METAL DUCTWORK
between all the ceilings and floors.

So all the walls, floors, and ceilings have metal in them.

With the old router, I had to replace one of the stick antennas with
a directional antenna aimed toward the part of the house where
coverage was weakest.  But since 802.11 N and AC use MIMO, I believe
that replacing one of the stick antennas with a directional antenna
would screw up the interference pattern that MIMO depends on.

I'm hoping that MIMO will solve the coverage problem that the
directional antenna solved with the old router.

Do any of you have any experience with routers in environments like
this?  If MIMO doesn't get me the coverage I need, what are my options?

 2. N vs. AC:

I have a 5 GHz cordless phone that I do not want to replace.  It
implements features that would be difficult to find a replacement
for, and even if I could, replacing it would be quite expensive.  So
it was important for me to figure out whether this phone will
interfere with an 802.11-AC router.  It took several months of
research, but eventually I determined that it definitely will
interfere with over half of the 5 GHz WiFi channels used in the U.S.

Since 802.11-AC only operates in the 5 GHz band, but 802.11-N
operates in both the 2.4 GHz and 5 GHz bands, 802.11-N seems like a
much better choice

 Content-Type: text/plain; charset=us-ascii

 Every night when I put my daughter to bed, I read her a book, or we play
 flashlight shadow puppets, or we watch videos such as The Duck Song, or
 Blackbeard, Bluebeard, Redbeard.  We watch netflix, youtube, etc.

 Recently I noticed, that all our video streams get interrupted annoyingly
 frequently.  Buffering every 1-15 minutes, it's infuriating.  Sometimes I
 can dumb down the connection, switching to CC instead of HD.  Sometimes it
 helps.  Not always.

 So I VPN'd into work (We have a non-split-tunnel VPN available), and then
 we can watch it, no problem.  It's the same content, being delivered over
 the same network, only it's encrypted and hidden from FiOS's routers.
  There's no other explanation, simply, caught red handed.

 When ISP's do something like this to Netflix, Youtube, etc, the end user
 perceives Netflix, Youtube, etc as being slow.  It's not my internet
 connection; my internet connection works fine for other things.  This is
 just Youtube being overloaded or whatever.  Well, that's what you get when
 you try to watch something for free.  Sigh.

 So I got to thinking, could encryption be used to circumvent greedy ISP's
 systematically?  If everything were encrypted and unidentifiable, then the
 only thing they could do would be to throttle *all* the traffic, not just
 the big content distributors that they want to shake down.  Then, the slow
 service would be recognizable to end users for what it is - a crippled
 internet connection, and not a deficiency of Netflix, Youtube, etc.

 Even if everything were tunneled over https, there are two obvious
 counters that the ISP's could take:  They could inspect the DNS traffic
 and/or SSL subject name to find the name of the server.  And/or they could
 try to create a list of all of Netflix's and Youtube's IP addresses, and
 throttle traffic based on these factors.

 Recently I noticed, that a lot of time when I go to download some file
 from some website, the content is actually redirected to come from
 s3.amazon.com.

 My point is to say:
 #1 the hostname doesn't need to be recognizable as *.youtube.com or *.
 netflix.com ... These guys could randomize all new DNS names all the
 time, so the exposed servername doesn't cause a problem.
 And
 #2 Content distribution networks don't necessarily have to have small
 recognizable IP ranges.  Especially with the expansion of IPv6.
Especially
 if large content distribution networks aggregate all sorts of traffic -
 netflix, youtube, and everyone else -

 If the content is distributed by a content distribution network, and LOTS
 of services use those networks, then the SSL cert could be *.akamai.com
 (or whatever) and if the ISP's want to throttle it, their only choice is
to
 throttle *all* of the content indiscriminantly.

Re: [Discuss] Why NOT use Linux?

[Joe Polcari]

Really - which linux does this?
I've built numerous servers with 24 SSDs and on the servers with no raid
controllers, the disks are always enumerated in the order of what sata
controller port they are plugged into for RH, Cent and Debian variants.

 I have a %pre script that runs in my kickstarts that fixes the

This is appreciated. It's something to add to my bag of tricks. Still, this
punctuates the point. Why do we need so many workarounds? Because the
kernel's behavior is stupid.

 For the disks -
 especially when you have hardware raid and you want the disks in a 
 specific order - you have to load the driver modules in the order you 
 want the disks seen.

This only works if you have different RAID controllers. If you have
identical controllers or many disks on a single JBOD interface then there is
no way to control the enumeration order. You have to fall back on hacks like
volume labels and UUIDs.

It looks like a great starting place for those interested.

 You don't see lawyers saying we need more lawyers. You don't see many 
 professions trying to actively recruit people.

Most people who could program computers don't know that they can.

It's true that the development of large software packages requires expertise
that is only developed over a long time of journeymanship, but look at the
available easy programming environments:

Python
Scratch
CAD programs with command line interfaces Web server environments

I hope we don't need more lawyers, but I encourage anyone to discover
mastery of this universal machine, the computer.

I just bought a $14.99 amplified antenna for my house. (Microcenter) I can
now cancel the last vestiges of cable TV. I am now broadcast and internet
only. I get all the local channels I was getting before encryption for
free.

I refuse to rent a box to decrypt channels that are broadcast through the
air unencrypted for free. Worse yet, basic cable is around $10 a month
with additional charges for additional television sets.

So, if you have two televisions, you pay comcast $180 a year for the
privilege of renting two boxes to remove the encryption that they put
there in order to make you need the box.

F*^king Thieves.

Re: [Discuss] rsync v. cp in data migration

[Joe Polcari]

Something I haven't seen mentioned here is that rsync copies to a 'new' file
in the same directory as the target, then moves the copy over to the target
file.
You can bypass this behavior and directly overwrite the target using
--inplace when not using a network.

Subject: Re: [Discuss] rsync v. cp in data migration

Correct me if I'm wrong here, but

1) Using a tar pipeline will (should) always be slower than a single process
(e.g., cp, cpio -p, rsync), because of the overhead of the two processes and
the system buffering for the pipe.

2) Copying to an NFS-mounted filesystem is likely to be less efficient than
alternatives (e.g., rsync) because of the NFS overhead -- it looks like a
local filesystem but in fact there is a lot of network processing happening
behind the scene.

3) I'm not an expert on rsync, but wasn't it (initially) written in a
client-server mode to achieve very high efficiency copying files over a
network?  Especially when updating (large) files which may have changed
slightly.

4) AFAIK, cp will not preserve hard links.  rsync will (though not by
default).  cpio and tar will by default.

 No, it tests is $1 exists in $PATH.
 I really hate bash pattern matching because I have to read the manual
 every time I use them.
 in this case '*:$1:*' looks for $1 anywhere in $PATH.
 
 
 Look at expressions. A path is delimited by colons. So, this means look
 for $1 anywhere in a path. You can easily test it. I have not looked at
 some of the boundary cases, but they appear to work since I've been
 using this for years.
 
case :${PATH}: in
*:$1:*)
;;
 Note that $PATH is prepended and appended by ':'. So, assume a PATH is
 $HOME/bin/usr/bin, the pattern is :$HOME/bin:/usr/bin:
 So, it will look for $1 anywhere between 2 colons.
