I have seen similar issues, some videos work fine but others seem to stop after 
either a few minutes or half way through. The same behaviour is seen on various 
computers, the same video stops at the same place.

I didn't have time and could not be bothered to look into it at the time and 
kind of put it down to one of those things that will be fixed later. 

So I'd be really interested in what the outcome is!

Agreed.

Slightly odd though that they are upgrading their network and then de-peering 
everybody who takes < 1Gb/s from them.
I don't quite understand why a content DELIVERY network would want to do this.

I'm not sure who's content they deliver but this does not seem like a 
particularly great way to go about delivering it. 

There was a network who commented earlier in the thread that they do 600Mb/s 
with them, that's not an insignificant level of traffic really, especially 
coming from a single CDN. I wonder if this not some slightly mis-informed exec 
at LLNW who thought they found a great way to extract more money to deliver 
content that they have already been paid to deliver.

I have had some rather odd issues with the SRX boxes but JTAC were pretty good 
at turning around fixes for me for my specific issues.

Since then I have had quite a lot of SRX boxes across the range running various 
MPLS services including MPLS over GRE with fragmentation/reassembly which has 
been working very well. Since 11.1R3 I've had no issues at all with them.

So yeah the new flow mode stuff had its issues, but as a *small* MPLS box it is 
very functional. Of course in MPLS mode, you turn the flow stuff off..

How do you enable SSH then?

Do Huawei routers even have SSH? It'd slightly ironic that there is fuss around 
getting a Juniper domestic image with SSH enabled and yet a Chinese vendor 
likely just gives it away.

So having said all that, has anybody here had good experiences of Huawei 
routers? Have they worked well in your networks and are you happy with them? 
I'm mainly looking for something small (1-2U) that will do Ethernet over MPLS, 
VPLS and L3VPN services.

L3 VPN Management

2012-03-06 Thread Leigh Porter

Folks,

I have a number of L3 MPLS VPNs. For example, there is the WiFi management VPN 
(WiFi  management interface). There is th systems VPN where things like RADIUS 
servers, Databases talk. There is a VPN for LTE OAM. There are alsomseparate 
VPNs for other LTE functions.

All OK.

Then are various sites I have a cluster of ops servers, syslogs, things that go 
ping, instances of cacti and our various vendors management systems. They all 
sit behind a firewall.

What's the nicest way of allowing the ops servers all talk to each VPN 
instance? At the moment I just us pretty normal L3VPN techniques so that every 
VPN sees routes tagged with the ops VPN target community and so that the ops 
VPN sees all the other VPN routes but the division between VPNs is maintained.

Or, would it be nicer to have the firewall have a foot in each VPN, advertise 
routes to ops systems to each VPN instance and receive routes from all the 
other VPNs?

Re: NANOG Operational TTL Alert for 160-bit Headers (aka IPv4)

2012-03-03 Thread Leigh Porter
He has a point. The IPv4 exhaustion problem was manufactured by the illuminati 
to usher in their IPv6 protocol (note the use of the number 6, the number if 
the beast. Combined with the tuple of source, destination address and protocol 
type this is 666!).

The illuminati want us to deploy IPv6 so they can use it to control people 
ready for the new world order.

It was all predicted by Nostradamus.

Innit.

Well indeed that is a valid point. All cloud to me means is that there is some 
abstracted instance of x and that it does not always relate to a particular 
physical device, indeed, it may well be spread around a few physical devices. 

I don't think there is any implied magic redundancy automatic failover move 
your instance to another bit of metal if something breaks in there unless 
that's specifically stated.

You dudes need to get with the times and put all this stuff in the cloud.

Ok so I joke a little.. But I did move a load of stuff from a couple of home 
servers to some VMs and it works fine. Less to mess around with and prob 
cheaper too. 

The only thing I keep at home now is storage.

Yeah please don't use PDF. There is nothing more annoying than getting an email 
about something important that had a PDF attachment to tell you about the 
important things. Lowest common denominator!

I used to use mailman for this, but we had a CRM system as well which was 
database driven. So I write a script to grab the right email addresses from the 
database every night and populate mailman.

Yeah done that a few times.. Now all our colo sites have a kit with laptop 
(that boots win 7,  XP and Linux) serial USB things, USB ethernet things and 
that has a DVD/cd burner and a stock of blanks and a 3G dongle thing.

I.e. everything I have ever had to go home/office/nearest-shop for..

So now when our guys to go colo, they can usually take anything and have most  
things they need there already.

Now we need to nail them down so people DON'T BRING THEM BACK TO THE OFFICE.

I had a vendor actually suggest that that ALL my customer traffic should 
traverse a firewall. I asked why and they said "Ahhh it the internet, must have 
firewall". I suppose this must have been a great firewall.

So yes I would agree with you, firewall nothing for your customers unless they 
are paying you for a specific service. Filtering known bad ports, well, what's 
a known bad port? Bad for one person may be quite important for another. Whilst 
filtering port 25 outbound may help prevent some bots from emanating spam, it 
certainly does a lot to annoy other people.

I have lots of MX80s and they have all been fantastic. But if you have no 
experience of Juniper it will be a different learning curve (one that is, IMO, 
worth the effort).

I have not used the asr1000 but it looks like a capable box. You would do well 
to look at the MX80 fixed chassis, it comes with 48 1G interfaces and 4 10G 
interfaces. They are pretty good value, I think.

At various seemingly random times over the past week I have had a DNS which is 
behind a firewall come under attack. The firewall is significant because the 
attacks killed the firewall as it is rather under specified (not my idea..).

It did originate from Chinese address space and consisted of DNS queries for 
lots of hosts. There was also a port-scan in the traffic and a SYN attack on a 
few hosts on the same small subnet as the DNS, a web server and an open SSH

We did this a few years ago and ended up writing the while thing ourselves. 
This included billing, subscriber management etc etc.

We integrates to salesforce.com for the internal front end and the user facing 
stuff we did ourselves.

It was a big project and took a team of six about six months. But we ended up 
with a perfect solution that did exactly what we needed and it was pretty good.

It handled within the order of users you mention, but we designed to 100k users.

We used radiator (highly recommended) with openldap back end. Multiple load 
balanced servers etc etc.

The worst thing we did was to build our own mail system. Not that it was an 
issue, it never went wrong, but these days I'd just send people to gmail or 
something.

Well really this is pretty much our fault. IPv6 has been on peoples 'back 
burner' for far too long. Additional vendor pressure and pressure at the IETF 
would have pushed things forward far faster had people actually been interested 
in doing so.

As per an earlier post, I am shocked at how I still have vendors coming to me 
with equipment that is nowhere near ready for commercial IPv6 deployment, it 
either just does not work, is half baked or is "on the roadmap".

So now we will reap the consequences and it will be at the cost of new market 
entrants (which I am sure will please some people) and perhaps cold hard cash 
for those who cannot expand their business or have to 'buy' address space.

I know a lot of people have been working hard to move IPv6 along both here, at 
NANOG and other events and with their vendors. It's because of those people, 
like Randy perhaps that we actually have what we do now else most people would 
still be stuck with their heads in the sand.

Well, I am sure it'll all be OK in the end...

Presumably organisations will check this and fake the appropriate paperwork and 
come up with some plausible excuse for requiring the space within the next 12 
months BEFORE they part with their cash.

It would be most amusing for somebody to buy space, hand over the money and 
then have ARIN deny the transfer.

So I do wonder, how is this policy is being enforced and will ARIN be 
investigating this current news item?

And it means you do not get 'noticed' as much. I work from home when I have a 
task to get done that benefits from not having to talk to people. A specific 
document that needs completing or some more PowerPoint waffle for a pointless 
meeting with people who won't get it anyway.

Other than that, I try to be in the office.

Do people really do that? Just dump a /24 of routable space on a network and 
use it? 
Fifteen years ago perhaps, but now, really? Or are these legacy installations 
with Cisco routers that don't do 'ip classless' and that everybody has

I am curious now as to what you would find port scanning for port 23 on some 
space owned by utility companies. Now, I'm not about to do this, but it would 
be interesting.

Does anybody know what really happened here? We're they just using some ancient

I think the point is that you access your servers from your work station and so 
if the workstation you use to access the network is compromised then your whole 
network is potentially compromised.

This is not really a well made point, sorry. It's about a firewall failing, 
perhaps due to software error or hardware issue or because somebody failed to 
correctly configure a firewall rule. 

The point about private space is that is forces security in a way in which 
public space and a firewall does not.

With private space, you are forces to explicitly configure NAT holes or VPN 
connections whereas with public space your boxes by default are accessible by 
the whole Internet. By default, on a private space network, nothing can get to 
it.

Well this is not quite true, is it.. If your firewall is not working and you 
have private space internally then you are a lot better off then if you have 
public space internally! So if your firewall is not working then having private 
space on one side is a hell of a lot more secure!

As somebody else mentioned on this thread, a NAT box with private space on one 
side fails closed.

Re: Arguing against using public IP space

2011-11-13 Thread Leigh Porter
I was involved in a security review of a SCADA system a couple of years ago. 
Their guy was very impressed with himself and his "Internet air-gap" but 
managed to leave all their ops consoles on both the SCADA network and their 
internal corp LAN.

Their corp LAN was a mess with holes through their NAT gateway all over the 
place to let external support people rdesktop to the SCADA network machines.

Of course it was all on private address space internally. 

So you see, when you put idiots in charge, your screwed whatever you do and 
private address space and NAT and whatever else will be no more then security 
by nice stickers and marketing.

Which may very well fail because all the routing is hosed. I'm not all that 
familiar with the potential implementation issues, but I would think that 
network-local caches would be in order. 

Even with local caches, I would expect a high incidence of change to trigger 
something sensible to mitigate this kind of craziness from happening. I am sure 
enough people have had incorrectly scaled RADIUS farms blow up when a load of 
DSLAMS vanish and come back again not to repeat such storms.

Yup it is pointless.. Mine are all ipadrress.domain which is of course,

This is what I used to do.

Any outgoing port 25 was sunk into a pool of SMTP proxies that I wrote. These 
proxies would look for signs of authentication and if they found them, the 
session would be proxied to the original destination SMTP server from the same 
IP address of the originating host.

Anything else was proxied to the pool of Ironports which would rate limit and 
otherwise SPAM examine the mail.

That way people using authenticated servers would be allowed through on the 
assumption that in all likelihood they were OK. Others who do not auth or are 
SPAM bots would be scrubbed and rate limited quite severely.

Our own customers were encouraged to use our outbound SMTP hosts which would 
either authenticate them if external or just allow them if internal, but with 
the SPAM scrubbing and less severe rate limiting enabled,

Customers who need a higher volume of outbound mail can call us and 
authenticate to the SMTP servers and we can set them a bespoke profile for rate 
limiting and message size etc etc.

That worked rather well because people's email got out and SPAM was largely 
stopped.

The Ironports were darn good boxes if a little pricey,

My iThings camp on WiFi all the time anyway as they are waiting for push 
updates, checking mail etc.

Of course, all these little things add up and add to the total network traffic 
(and port counts for NAT)so they all take a toll on networks.

I agree though, I would have liked to have seen iMessage cross platform. One of 
the great things about Skype is that I can talk from PeeCee to MAC to iThing to 
whatever..

Re: passive bandwidth estimation

2011-10-05 Thread Leigh Porter
I used a passive TCP RTT calculator and TCP re-trans monitor to guess the 
conditions to a host or group of hosts with some success. I the. Derived the 
network "weather" from this and it worked pretty well to dynamically tune DPI 
box policing for wireless networks.

It also makes cool graphs. Especially if you add other parameters and do it all

People have been bleating about routing tables sizes for years and everything 
has been fine. You could argue that the bleating has helped keep the size down 
of course, perhaps it has.

I wonder what would happen if a new ARIN member requested an IPv4 block of say 
a /16 for a new business? Or even a smaller block. I don't know what the 
current ARIN rules are but RIPE will currently give out six months worth of 
space. Now, in six months, I don't expect there to be any left anyway, so what 
will likely be all the v4 you ever get.

Very soon it'll be nigh on impossible for new entrants to the ISP business to 
get their own v4 space.
