I have seen this in SEO-poisoning type of webpage defacement.  They
anchor a javascript in the main website "frame" and it generates
optimization "links" using a numeric suffix or ?argument so that they
appear as separate links.  If the crawler is recognized  (e.g.,
googlebot) then the SEO page is returned.

Your concern about a lack of any prefix-lists in the documentation /
examples you have read is justified.  If you are connecting to an IX
it may offer route-servers which have prefix-lists maintained by the
IX staff and tools.  However, as you may already know, you will only
receive the "best path" to each prefix from an IX route-server.  This
is often a motive (among others) to establish direct eBGP sessions
with other IX members.  Once you start doing that, you had better
filter routes from those neighbors, or you will subject your network
to your peers' mistakes and glitches.

If you imagine that the IX has other members like yourself, who also
do not know much about BGP, then you can understand why you do not
want your peers' mistakes to cause outages on your network.

Doing a "cut, replace, and paste" from online examples is obviously a
bad idea.  If I were you, I would find a local consultant (perhaps
someone on the staff of the IX or another member) who can assist you
with your initial configuration, and help you in the event of a severe
emergency.  Otherwise, frankly, you are going to be better off by just
buying transit from Verizon and being single-homed.  The added
complexity of BGP is not an asset to an organization that doesn't have
adequate expertise.

And it's reasonable to accomodate the customer that asks, and
reasonable for a customer to ask for
a temporary ACL in such situations.

However, it's also reasonable for the provider to refuse,  and there's
nothing wrong with that, unless the provider agreed that they would be
willing to do that, and then refused to do something they had already
agreed to do.

The provider might be especially dissuaded from responding and
providing a temporary
ACL for free if the DoS is a "small" one based on the provider's
definition of small,
or if the provider doesn't have  or won't allocate the resources to
respond, without
charging a fee to do so.

Or its a cut rate hosting service, and the customer refused to buy the
"managed filtering"
firewall  (or whatever solution). In that case, it's reasonable
for the provider to counter the
request with  "You can buy our such and service, and we will gladly
implement that"


If this is something you want to be sure you can do,  then you should
ask the provider
about it before signing that colocation contract for IP connectivity,
and make sure you have it in writing
that the provider will create an ACL on your interface of sufficient
length to do what you want..

And be sure you have worked out  with the provider how this effects
billing in advance.
It's quite possible you still have to pay or have said dropped traffic
counted against your commit.

Re: Random five character string added to URLs?

This type of behavior is quite common when protecting web assets to eliminate 
zombies and such, but its usually something you would see back to the clients, 
not tp the server.

Also, IIRC, the LOIC DoS tool had this ability to create random strings in the

We have always accommodated temporary ACL's for active DDOS attacks. I

I do feel it is bad practice to regularly implement customer specific

Re: Outgoing SMTP Servers

2011-11-01 Thread Carlos Martinez-Cagnazzo
The point to make here is:

- if an ISP takes the path of blocking tcp/25, then they MUST
communicate this appropiately to customers and other users
- they also MUST provide alternatives: SMTP over SSL should be allowed
(tcp/465), authenticated relay, but *something*.

IMO blocking 25/tcp is a side-effect of the failure of the whole ISP
system to decisively deal with spammers. It's easier to blind-block
25/tcp than to do proper investigations and to collaborate with law
enforcement. I have tried to hand reports with *static* IP addresses,
contract identifiers and even home, mobile and work phone numbers of
known spammers in Uruguay (I happen to have my personal feud with one
that sells dog food), only to be shelved by management on the fears of
legal action.

I have also trouble swallowing the argument of "blocking 25/tcp is
great because it avoids us getting into black lists and reduces spam".
Yes, sure, but that doesn't prove it's the right approach in the long
run, as you are dealing with symptoms and not causes/sources.

It's the same thing as having tons of aspirines each time you have a
headache. Even if the pain subsides, you might still have other
underlying conditions that in fact are being masqueraded by your
"solution".

So, as it is often the case in society, we all pay the price.

Re: using IPv6 address block across multiple locations

My take on the issue is that your providers are wise in not wanting to

You should get multiple prefixes, from the same or different RIRs. If
there are policies in place which do not allow you to do so, I think
it's a good time to discuss them.

In fact, if you have one or more providers which, in common, serve
multiple POPs, it may be desirable to tag the more specifics (/48s)
as no-export and leave the /44s exportable.

In this way, you can avoid unnecessary DFZ pollution.

I agree with you except this last statement.

If you have a need for more than a /48 and you can announce the aggregate
and not the more specifics, it is perfectly valid to get more than a /48 and
you should do so in a way that allows you to announce only the aggregate
so as to avoid polluting the DFZ.

DFZ pollution is not about prefix size, it is about the number of prefixes.

In all cases, one should attempt to implement the minimum number of prefixes
necessary to effect your desired (or needed) routing policy.

Prefix size, OTOH, should relate to the number of end-sites served where
each end-site gets a /48.

through some other of your POPs (security or other considerations); if
this is desirable you may announce the whole aggregate (like /44)
additionally to /48 from all or some of the POPs; optionally you may
wish to announce /44 with community 'no-export'


You really don't need to tag the larger block with no-export.  In fact,
if the POPs are suitably interconnected on the back end, you really
don't need to advertise the /48s all, and just advertise the /44. 
Depending on your upstreams, you might be able to tag your advertisements 
with certain BGP communities (will vary from provider to provider) to give 
you some degree of conrol over traffic distribution.


Getting back to the original point, unless someone does something odd 
with their BGP views, the /48s will be preferred because they're smaller 
(more specific), and the /44 would only be used if a corresponding /48 
prefix doesn't exist in their BGP view.

Re: using IPv6 address block across multiple locations

2011-11-01 Thread Dmitry Cherkasov
Thanks to everybody who responded.

To summarize it all, these are the guides for non-ISP company to use
PI IPv6 addresses:

case 1: single POP, no plans to have more
- get single /48 from your RIR, announce it to one or multiple ISPs
that POP is connected to

case 1a: multiple separate POPs (no VPN interconnections)
- the same as for case 1 but for each POP independently; each POP has
individual AS, btw

case 2: extranet like multiple POPs interconnected with VPNs
- get greater then /48 block (like /44) so each POP gets its /48 part
- each POP announces its corresponding /48 prefix to their local ISPs
- decide if you wish that traffic from Internet to some POP passes
through some other of your POPs (security or other considerations); if
this is desirable you may announce the whole aggregate (like /44)
additionally to /48 from all or some of the POPs; optionally you may
wish to announce /44 with community 'no-export'


As for /48 IPv6 blocks being like /24 for IPv4.
It really seems that /48 may be the most popular PI block and this may
lead to overcrowding of DFZ. Probably, this is logical consequence of
getting bigger address space. We needed more IP addresses and we get
them. Anyway getting greater then /48 just because you do not want to
pollute DFZ is not justified.

Thank you.

Hi Payam,

Some of what you mention can be handled with Netdot 
(https://netdot.uoregon.edu).

There is built-in support for maintenance contract definitions, but some
customization might be required. The good part about netdot is that it
will automate some of the inventory management if it has SNMP access to
your devices. Asset mgmt support is rather good for Cisco equipment, but
would have to be tested for other vendors.

Cheers,
Phil

consumer DSL problems

2011-11-01 Thread Mike Reed
Hi folks,

It would seem that my home broadband provider (Orange, formerly known
as Wanadoo/Freeserve) have made some networking changes at the
weekend. The first I knew of it was when my DSL router refused to
connect. It's a vendor-supplied Siemens Gigaset SE572. While it's
probably not the best router in the world (most consumer routers are
risible), it was generally fine. On complaint, they tell me it's
'old'. Closer inspection reveals it's picking up the DSL carrier
signal fine, but failing during LCP negotation

Is there a common policy on rendering vendor-supplied CPEs unusable?
As a network operator to residential users, would you notify any
potentially affected users before making such a change? I am grateful
for any insight.

Kind regards,
Mike

Hi,

I would suggest you use the element management software provided by your 
vendor. But you may want to take a look at www.ziptie.org for an alternative.

Network Asset/Service Track/Management

2011-11-01 Thread Payam Poursaied
Hi all

I'm looking for a system to keep track of network assets and also periodic 
services in each pop site. Currently we have
about 500 pop-sites. In each site we have DSLAMs, Linecards and also some 
passive equipments including terminals, racks
and ..

Also each site may have some recurring fees/services. Something like transit 
link, power, rental space and .

 

Could you please share your experience with me
