Is this the new BGP DoS attack? Or did the Internet routing table just double in two hours from new ARIN policies ;) BGP table version is 12415019, main routing table version 12415019 78724 network entries (129728/289118 paths) using 18517816 bytes of memory 17935 BGP path attribute entries using 2440004 bytes of memory 16236 BGP route-map cache entries using 259776 bytes of memory 0 BGP filter-list cache entries using 0 bytes of memory Dampening enabled. 6558 history paths, 4405 dampened paths rob

Rash assumptions about local telco policies
by Sean Donelan 08 Oct '97

08 Oct '97

It is always a bad idea to generalize anything about local telco practices. There are lots of options for configuring ISDN lines, analog lines, or channalized trucks and local telco's seem to thrive on doing things their own way. Even ordering the same thing from the same local telco doesn't mean you will end up with two things configured the same way. Ascend will report the "calling and called number", I'm not sure whether the calling number is CLID or ANI or its just whatever the local telco decides to send. I think AT&T provides ANI over their PRI's while local telco's usually supply CLID over their PRI's. I haven't seen an Ascend with a channalized T1 report any in-band signalling of calling or called number information, but I don't have a copy of the new ascend manuals so there may be an option I'm missing. So depending on how you configure your ascend and what you order from the telco, you may or may not get calling number information. Livingston and Cisco have many of the same configuration options. And then you have the mess of VPOPs using equipment like NORTEL where the records may be spread over a couple of organizations. In the end ANI/CLID/etc is just a lame substitute for knowing who is your customer. As long as instant dialup accounts are the norm, I expect ghost customers to also be the norm. True, some percentage are stolen accounts, spoofed addresses, and so forth; but in my experience the ghost customers are a huge source of the current problems. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

RE: QoS/CoS interest (again) & Fiber Cut ....
by Peter Cole 07 Oct '97

07 Oct '97

Telescan, Inc. Wants the best access money can buy(within reason). We want to get the lowest loss connection to our customers as possible. We will shortly be triple homed with Sprint, MCI & UUnet by T1s. If I were convinced that I could find a better way to move data to and from our customers I would be moving to use those solutions. What most of the Internet access providers don't seem to realize is that we(corporate America) all still have lots of private lines for performance, security and Reliability. We are currently spending as much on private lines as on Internet access. Security is well on the way to being solved. Performance and Reliability are paramount. If we got better performance from the Internet we could move more applications and services to the net. This would mean bigger sales for our access providers.

SPAM attack on our support group
by Dennis Simpson 07 Oct '97

07 Oct '97

Last night, our support mailing list was mailbombed, and subscribed to mailing lists. Anyone else get their support mechanisms hit, or are we chasing someone who doesn't like us? Private replies would be most appropriate, if there are several incidents, I will summarize back to the list. Thx, dennis

QoS/CoS interest (again)
by Paul Ferguson 07 Oct '97

07 Oct '97

Back in May, I sent a message out to the NANOG list asking about superficial thoughts on QoS. I also summarized received responses to list later. Well, I'd like to pose the same question again, to gauge whether the climate has changed substantially. Please take a moment to review the original question, and feel free to respond to me personally, or to the list in general. Thanks much, - paul On Wed, 21 May 1997 14:04:35 -0400 Paul Ferguson <pferguso(a)cisco.com> wrote: > I'd like to get a feel for what the temperature level > is in the ISP community for this issue -- I have a vested > [personal] interest in understanding what your understanding > & implementation plans are in this arena. > > Please send your thoughts, requirements, bitches, etc., to > me personally, or preferably, to the NANOG list; it is a > greater audience than myself that wishes to understand these > issues. > > Thanks! > > - paul >
