So looks like this may be a reason not to use UBNT stuff for our backup links.  
Looks like the highest I can set the MTU is 1515 on a couple units and 1524 on 
another.  Neither capable of 1528 or more.  

 

I'll have to find some brand new hardware and see if it can go higher.

 

How big of a performance hit are we talking here?  Potentially requiring double

We are evaluating vendors for this at the moment.  Ciena is looking like the

So far we have rejected Cisco, Juniper, Performant, Accedian, and Extreme as 
vendors.

To answer Forrest’s question - yes, we do need faster recovery than we can get 
from MSTP, OSPF, MPLS.   While those protocols have worked well, they don’t 
have the recovery time we want.  

Other things we are looking for beyond quick recovery time:

Carrier Ethernet Services (Metro Ethernet Forum) Ethernet OAM Performance 
Monitoring (Y.1731)

I want to be able to offer carrier type services (NNI, E-Line, E-LAN, E-Tree, 
E-Access) to other companies over our wireless and fiber network.  If you want 
to sell services to cell companies they are requiring Y.1731 (Performance 
Monitoring) at the handoff. 

We already have pieces of this in place over the wireless network using Q-in-Q, 
but want to extend this further.  We currently have one other ISP set up 
selling services over our wireless network with transparent (to the customer) 
Ethernet delivery back to the providers network.   It’s pretty cool in that 
they can install customers anywhere on our Canopy network and deliver the 
Ethernet traffic back to their network.  We don’t care what VLAN, IP

General reminder: when hardcoding Ethernet, you must hardcode both ends to
the same settings.  You cannot hardcode one end, as autonegotiate cannot
properly deal with that scenario.

Removing advertised speeds and duplexes, on the other hand, can be done on
one end.

Also, mikrotik's safe mode is your friend for this sort of thing.  It's not
quite as good as a cisco 'reload in 5' command, but it's certainly better
than nothing.

My worry about getting cut off is from the AP, not the Mikrotik.

And I should clarify, I'm not looking for a way to bandaid this with
hardcoded speeds, it should work with auto and does most places.  And I
think hardcoding to 100M may just leave me with the link flapping up and
down, which seems to be the fundamental problem.

What I'm trying to find out is if other people are seeing this.  Cambium
supposedly did a FW fix awhile back for 450 AP Ethernet problems, I think it
may even have been specific to connecting the AP via a POE that does not
support Gigabit.  I'm trying to determine where the problem might be - the
list of suspects could be router, POE (Packetflux SyncInjector), surge
protector (WB APC), cable (~100 feet of Belden shielded Cat5e), or AP.

At one site, I have 4 APs and 2 of them are exhibiting this problem.  I want
to swap out the APs last because that's an expensive experiment.  I am going
to try swapping Mikrotik ports, maybe SyncInjector ports, maybe replace or

something in the FW and then broke it again in 13.2.

I'm also wondering if the 450 APs would be happier talking to a non gigabit
router port, or maybe with the gigabit version of SyncInjector, although I
have other APs that are happy with this setup.

General reminder: when hardcoding Ethernet, you must hardcode both ends to
the same settings.  You cannot hardcode one end, as autonegotiate cannot
properly deal with that scenario.

Removing advertised speeds and duplexes, on the other hand, can be done on
one end.

Also, mikrotik's safe mode is your friend for this sort of thing.  It's not
quite as good as a cisco 'reload in 5' command, but it's certainly better
than nothing.

Re: [AFMUG] outlook becomes intermittent in satellite office

Then you need to check your maillogs; check to see if the message was
accepted by your SMTP server, and see what happens when it tries to send it
along to the next server.

SMTP isn't very robust, but your email program will give you some sort of
error if it doesn't get '200 ok' or suchlike when submitting  mail.

 This is a bizarre set of symptoms, and I really don't know what is going
on.
 So I will articulate the facts, and maybe one of you can tell me what 
 might be wrong.

 We have a business subscriber that occupies several buildings.  The 
 buildings are separated by enough distance that we have to 
 interconnect by means other than vanilla ethernet.

 Our service is delivered to their main office.  Our SM is installed 
 there (PMP450), plus a Mikrotik router on ROS 5.26.  The Mikrotik 
 manages 4 VLANs;
 1 business VLAN, which is bridged to the main subnet in the main office.
 The other 3 VLANs are guest VLANs; each on their own
 (private) subnet.

 All the computers, etc. work fine in the main office.

 The main office is connected to the guest building with a VDSL modem 
 (~~ 800' phone line between buildings).  Not much occurs in the guest 
 building; it has a couple of WiFi APs for the guests.

 In the guest building, we've installed an RB260GS switch.  It divides 
 the various ports out to 4 different VLANs.  A couple ports are the 
 business VLAN, plus 3 different guest VLANs.  The SFP port on the 
 RB260GS is used to connect to the satellite office another couple 
 hundred yards beyond the guest building.  The SFP port is on the business
VLAN.

 At the satellite office, they have 2 computers.  Everything on the 2 
 computers in the satellite office seems to work just fine.  Web 
 browsing, streaming youtube, etc.

 However, when they run Outlook, some email doesn't go to the
destination.
 As far as we can tell, it gets to their off-site SMTP server (Globat), 
 but some of it doesn't ever reach its destination. If they use their 
 web-based email, the email works every time. Also, the POP part of the 
 email works just like you'd expect.

 Today, we moved one of the computers back to the main office, and 
 surprise, surprise, Outlook starts working just like it's supposed to.

 We've run extended ping tests between the satellite office and the 
 main office, and there is no break in the link.  It seems solid.  So 
 where/how is the SMTP part of email breaking?

 What tests can I run to figure this out?

Re: [AFMUG] outlook becomes intermittent in satellite office

2014-11-03 Thread Shayne Lebrun via Af
Ok, well, there's not many places SMTP email can fail silently.

1: your mail server cannot/does not accept the mail.  Your email program
will display *some* sort of error message.

2: Your mail server cannot/will not forward the message to the MX for the
domain in question.  You'll almost invariably get a mailer daemon
notification about this, though your email program/spam filter/anti virus
might do something stupid and hide it from you.

3: The MX for the address cannot/will not accept the message.  Again, it
will respond with a reason, and your mail server will almost invariably
forward that along to you.

4: The recipient's email program cannot/will not get the email from their
mail server.

And number 4 is likely what's happening here.  The email is getting where it
needs to go, then getting shunted to somebody's spam folder or something.

Mail server logs will tell you exactly what's happening.  Telneting to your
mail server's submission port (usually 25 or 587) and making with the ESMTP
commands might also shed some light.
From memory, and it's been a while since I did direct SMTP support:
EHLO enter
MAIL FROM: myaddr...@mydomain.com enter
RCPT TO: youraddr...@yourdomain.com enter
DATA enter
Hello this is a message.  It will look odd in most mail programs, because
you're skipping some of the headers that aren't strictly necessary, but most
email programs will expect.
Still, you'll get back SMTP status codes, as well as a brief description of
any problems encountered.enter

the email gets to the email server (and I don't know if it's exchange or

 Have you tried temporarily a different email client from the problem

 The most useful thing, especially if you or the customer controls the 
 mailserver, is to look at the logs right after sending an email.  Was 
 the message received?  Was it relayed and did it go to the right 
 mailserver according to MX records and to the right recipient?  Was it 
 accepted by the recipient's mailserver, and if not, what SMTP error 
 codes were logged?  Is it still in the mailserver queue being retried?

 If you had packet loss so bad that outgoing email didn't work, I'd 
 expect trouble with incoming mail, webmail, web browsing, etc.

 And if Outlook is unable to send the email, you should get an error 
 message, and the message should be stuck in the Outlook outbox.
 Unless some antivirus program is spoofing to Outlook that it was sent.

.a has only 54Mbit/s Phy rate. RB800 is quite powerful.

With N/AC you see a lot more cpu work.

 

With TDMA protocol the cpu has to work in fixed cycles with low latency.

So if it is busy while it has to send the next map for the cpes at an exact 
timing 

the whole sector suffers.

 

So the cpu should stay at a low level to keep the protocol running.

The CPU usage doesn't tell you RF congestion, retransmits, etc. It just tells 
you how busy the CPU is. If you're running NV2 on an A card in an RB800, your 
CPU is going to be low, but your radio is going to be very busy and yet not 
including that information.

I'd say that knowing how busy the radio is is more important than knowing how

Most people end up with a set of three or four configurations.  Ie sitemonitor 
plus a injector is one configuration,  a sitemonitor by itself is another one.

If you put the modules you don't ever monitor at the end of the list then you 
can reuse configurations. Ie, a sitemonitor and syncinjector is the same as a 
sitemonitor, syncinjector, and Poe as far as monitoring goes.

OK.  I think I have an approach. The SiteMonitor plus all its expansion units 
is not the device.

The device is the SiteMonitor plus the index of the expansion unit.

For example:

*   SiteMonitor, index 0 is the SiteMonitor device
*   SiteMonitor, index 1 is the 4-port POE device
*   SiteMonitor, index 2 is the SyncInjector (first instance)
*   SiteMonitor, index 3 is the SyncInjector (second instance)

and so on.

So when you add a SiteMonitor, you just add the SiteMonitor. If you add another 
Packetflux expansion unit, you have to add it knowing which index (AKA slot) 
it is.  Put the device in a different position, and you need to update the 
index.

TBH there is one thing I love most about a CentOS distro over Windows. 
IPTables. Windows firewall is pretty lame in comparison, with open ports you 
will “possibly” use. At least IP tables initially comes with a “block all” 
setup and you just go in and poke the tiny holes you need. Obviously a 
security-conscious person is going to shutdown system services you don’t need, 
but for the initial setup IPtables is pretty badass (and far more simple).

 

@Ken, I am in the same boat as you. We applied updates Thursday and again 
Friday for bash on our CentOS 5/6 boxes. So far so good though, I’ve been 
monitoring the logs of our boxes running httpd and so far nothing out of the 
ordinary has appeared.

Originally, I responded to this:

Ø  “I think the articles have maybe overstated the risk a bit, since you would 
need to either authenticate (at least as a regular user) to get to a shell, or 
find a publicly exposed script that will pass an environment variable to bash 
for you.

And asked you not to think about security in those terms.  Don’t assume you 
understand all the possible attack vectors, don’t assume that because certain 
other things need to happen, you’re invulnerable, etc etc.  When you get right 
down to it, though, UNIX really wants to land you at a shell, and bash is the 
default shell in a lot of places.

 

You’re certainly listed a whole bunch of issues in the software world at large, 
dedicated applicances, etc etc and I certainly sympathize with a lot of the 
issues you’ve raised.

 

Of course, the slightly less empathetic sysadmin in me says ‘too bad; you put 
public-facing server on the Internet, you have an obligation, and a 
responsibility to maintain it properly.’  I argue in my head with him A LOT.

 

Yes, absolutely, you can mitigate the issues you raised in your last email to a 
very reasonable degree with proper firewalling, internal processes, etc etc.  
And it sounds like you’re cognizant of the need to do that, so that’s great too.

If you don't have a surge suppressor then you need a tower climber to change
the switch.  Either way, a climb is required.

 

Remember surge  suppressors are not like fuses.  In the sense that they
don't blow with every suppression event.  They can shunt some spikes to
ground, save the switch port, and live to fight another day.  If they do
give their lives to save the switch then you need a climb.  But would have
likely have needed that climb anyway to replace that switch or change ports.
So suppressors at the top will reduce the number of climbs although you will
never know how many times the surge suppressor saved you.

 

Maybe Chuck should put a strike counter circuit in the suppressor and change
to a subscription model.  You have to pay for each strike that he saved you
from.

Those putting Switches at the tower top, what kind of protection are you

Are you using surge suppressors? 

 

I was thinking of using Industrial POE switches at the top, feed DC and
fiber, then short runs to the radios (epmp and 450 are poe compliant) 

 

Should I go straigt to the radios?

Re: [AFMUG] ePMP Force 100 beefy

2014-09-18 Thread Shayne Lebrun via Af
(gosh, I hope I'm allowed to say all this, but what the hell, they didn't
say 'and don't repeat nothing!' and it's not like other road-show goers
can't ask themselves)

Oh, I'm sure it'll be user-definable, on the 450, in terms of how to sync.

The thing is, with the ePMP, you have exactly three options; something like
75/25, 50/50, and 30/70.  Those are all you get for sync options; the
downlink percent.  They were very clear that 'max range' is NOT a timing
parameter.

So, making your 450s sync with your ePMP is going to have some tradeoffs,
and that's to be expected.

As to the 100/430s, it was pretty unambiguous that those would never sync
with the ePMP.  Or have their MTUs increased.  Or all sorts of other stuff.
The idea they seem to be moving to, and this is my conclusion rather than a
direct statement, is that the 100 series gets flat-out replaced with ePMP,
you put 450 where you have needs that the 450 meets (no guard bands, smaller
latency, etc etc) and that the 430 is a red-headed stepchild.  Don't ask
what the 320 is in that analogy.

Also, there's a new licensed PTP radio to be announced in a month or so,
which, supposedly, a better pricing structure.

I was told there will be various options coming soon to make all of this
stuff sync. There will be advantages and disadvantages to each way of doing
things, but at least it will work. As far as the aging PMP/PTP100, I assume
it will do 5ms framing because that's what 900 does today, so it is possible
on the platform, obviously with a latency hit, but what can you do.

 Increasing the frame duration to match the ePMP will double the

 450 is being made to sync with ePMP, by increasing frame duration to
match.
 100/430/320 will likely see no new changes.  This is what I got from 
 an ePMP roadshow.

 I am guessing if anything, you will see Canopy (or at least 450) sync 
 with ePMP/320.  Seems like it would be easier to make the FPGA based 
 radio use a longer frame than to make the Atheros based radio use a 
 shorter frame.  I'm sure they already tried that.

 Definitely looks like a Laird/Pac feed design. That has to be a pain

 When they get these things to sync with Canopy and get the PTP

 It would lead you to believe the antenna system is dual slant. All
