We've been tracking this dynamically for a while in order to make sense of flow data traces - using a plethora of reliable (as well as dubious!) sources - including running some of the more popular p2p apps to see what ports they choose. Of course, there are many problems with using tcp/udp ports to identify apps - some apps use randomly assigned ports (sometimes after negotiating the connection on a well known port; like most streaming video protocols); some apps allow users to override ports, which many users do in order to circumvent firewalls; and there is much duplication across ports. But, try the attached lists (one by port, one by app, and one shows a grouping we use for "common application classes" e.g. "mail" or "peer to peer" etc.). I'd greatly appreciate fixes or updates. [NOTE: attachments not sent to nanog-post - if you want them, email me privately.] Of course if you really want to accurately account for traffic by application, there is no substitute for passive sniffing of full headers (not scaleable, and certainly can raise privacy issues). -fred

BT network outage
by Sean Donelan 21 Nov '01

21 Nov '01

The joy of single provider service. British Telecom lost most of its national IP backbone on Tuesday affecting DSL and Dialup service across multiple ISPs in the UK. According to news reports, this affected almost all DSL service in the UK. What happened to BT? Is this a unique "feature" of the UK marketplace or can the same thing happen in the USA?

win95 and IEAK6.0
by Bill Larson 21 Nov '01

21 Nov '01

It appears that without telling anyone Microsoft decided the Internet Explorer Admin Kit version 6.0 which generates a custom IE web browser for ISP's would no longer support Windows 95. I do not know about the rest of you however, I have many Windows 95 users still signing on to my service. I think it is time to let Microsoft know our displeasure about this clear abuse of their monopoly position. Once someone else confirms this behavior, I intend to raise a stink with the national news media, the federal government and the nine states that are still suing Microsoft.

Slightly OT: Anyone know of a concise port list

Anyone know of a concise port/port range list for profiling various client code out their (no /etc/services isn't the end all). Looking for ranges for Napster, Audio Galaxy, BearShare, etc, besides the WKP's. Doing traffic custom traffic profiling with NetFlow and trying to get a concise list.

It may be instructive to look at the windows update website (windowsupdate.microsoft.com) and note the fine print towards the left of the page. Check out the Win95 Legacy page it references. P.S., you have to be running Win95 to find it. The browser lets the site know what platform you are running on, and "customizes" what you can see. For instance, I cannot find that page browsing from IE6/NT4. James H.

Invalid IN-ADDR.ARPA information coming in from HINET

HINET.NET appears to be claiming authority over IN-ADDR.ARPA and is poisoning DNS caches. Anyone try to contact them to make this stop?
