Content Injection Appliance
by shane 28 Mar '01

I need someones help, I saw a product at ISPCON Fall in CA. And the product allowed me to have it operate on my core routers and watch web traffic and allow me to "Inject" a "pop-up add" or a service anouncement. I have been searching my ISPCON "stuff" I collected and I can't find it, and it is driving me crazy. What I want to do is set up this box to watch web traffic, and when a new user logs in it checks to see "for example" if he has new mail on our mail-server, and pop-up a little window on his/her screen alerting them about this. But I don't want to make the user be required to use our home page as the start page. Can anyone tell me the name of this product, I am already aware of FrontPorch and their product would work, but they require me to allow them to to advertising to my customers, I don't want that. shane brath TDS.NET Internet Services shane(a)bratnet.net

Re: RADIUS info for traveling users ...
by Mohan Sundar 28 Mar '01

28 Mar '01

Thanks for your responses and correcting my understanding. What i understand is policies are stored in a centralized policy server, and these are pushed to the Access Servers thru some mechanism, like SNMP or file transfer, etc. What is achieved by RADIUS is just getting pointer (like filter name) to the policy corresponding to a subscriber when a subscriber dials in, and dynamically binding that to the access interface in the access server. How are these policies then dynamically generated, based on the IP address that is dynamically assigned? Do policy servers also have policies based on subscriber-name (or ID)? What is the interaction between policy server and RADIUS? Thanks again. - elwin --- Brett Frankenberger <rbf(a)rbfnet.com> wrote: > > A Service Provider, having several POPs, I presume > > will be using at least one RADIUS server that is > > associated to each POP, and are usually colocated > > at the POP, along with the RAS, aggregation and > other > > IP service devices. > > For most providers, you presume incorrectly.

RE: Microwave...
by Paul Lantinga 28 Mar '01

28 Mar '01

I recall that when I was working in Bangalore, India, another multinational company (I think it was Siemens but I can't recall definitively) had to poison the vultures that consistently perched on their microwave dish to get reliable point to point. Given the complete non-regulation of spectrum out there, at least once we had another provider clash with our spectrum[1], forcing us to flip the dips until we found a clear one. However, when it worked, it was incredibly solid. Chocolate bars in India were usually melted already when you bought them. ;) [1] Sometimes they would clash physically with us when they mounted extra dishes on the tower in the downtown location - as in, some guy standing on our dish to mount his. -- Paul LANtinga Q9 Networks, Inc. > -----Original Message----- > From: John Fraizer [mailto:nanog@Overkill.EnterZone.Net] > Sent: Tuesday, March 27, 2001 9:21 PM > To: Dee McKinney > Cc: NANOG > Subject: RE: Microwave... > > > > > We've got a customer on a DS3 microwave shot.

late DEW - 2q2001
by Bill Manning 28 Mar '01

Hi, I appologize for duplicates. Its almost time for the next quarterly walk of the inverse tree of the DNS. Since 1997, I've been walking the in-addr tree looking for numbers of delegations, accurate delegations, and types and styles of error conditions. So... this is a heads up that you will be seeing zone transfers being generated by a couple of the collecter machines here. For those of you who utilize BINDs access controls, I'd appreciate your inclusion of the collector machines in allowed transfers. The expectation is that they will be the following IP addresses: 128.9.160.57 and 198.32.4.13 If there are any questions or concerns, I'd be happy to talk about them. Past data has been presented at IEPG, Apricot and RIPE meetings. The expectation is that future data will be presented in the same and similar forums. Past data may be viewed at: http://www.isi.edu/~bmanning/in-addr-audit.html --bill 310.322.8102

Experience with Larscom NetEdge 85M's
by Jon Stanley 28 Mar '01

28 Mar '01

Do any of you have any experience with troubleshooting unacceptable amounts of latency and packet loss on an Edge 85? Everything looks cool, the DS3 circuit going into is clean, it's not oversubscribed, but the latency and (mainly) packet loss continue. I am at a complete loss as to what to do with this. The packet loss appears to be consistent, however running an mtr at this time is telling me that it's not there. I know from looking with my own two eyes that it was there and worse than ever several hours ago, but it seems to have calmed down now. Any suggestions as to where to go with these things when conventional methods of troubleshooting (including moving the customer to a router closer to the NetEdge) seem to have failed me? 11. xxx.xxx.xxx 2% 594 601 54 42 61 140 Thanks in advance, Jon

RE: MBone access
by Martin, Christian 28 Mar '01

One of the things that appears to be a major impediment to large-scale deployment is the lack of SA transitivity, which is limited by MSDP's RPF rules. Therefore, the Internet needs a dense mesh of MSDP peerings to allow any-to-any connectivity. As of now, this is not the case. SSM will fix this. regards, chris > > Dear Jared; > > I could do this at NANOG 22 if there was any interest.

Roaring Penguin - Re: PPPoE server software?
by Karl 27 Mar '01

27 Mar '01

Hi Matt, I recalled reading a PPPoE thread on a list a few months ago, so I grepped around and found something on the Mid-Atlantic LUG archives: http://boudicca.tux.org/mhonarc/ma-linux/2000/2000-Oct/msg00229.html At that page, Billy Ball breifly sketches out how you can set up PPPoE with tools from roaring penguin: http://www.roaringpenguin.com/pppoe/ If you can't find everything you were looking for on the roaring penguin page, and msg00229, you might find tweaks in the PPPoE threads here: http://boudicca.tux.org/mhonarc/ma-linux/2000/2000-Oct/index.html I hope the two first URLs give you the PPPoE server leads you were looking for. -Karl PS- sorry if you got this twice.

Of course, many commercial providers consider this highly confidential data and don't share it, assuming they reliably collect it at all. The last commercial provider I saw with any public traffic analysis was ANS. The academic folks have bits and pieces from various networks, but as I suspect you know, it comes and goes. > Netflow data from various sources is proving to be the > most useful, but I need more views.

A number of the intrusdion detection/anti-DDOS vendors may have probes located where they can collect some of this information. And depending on the permision of the customers' the exchange point operators could assist.
