RE: What kind of cable is this?

Almost all cable you will work with will have identifying characteristics on the sheath i.e. what it is, who made it, and what standard it conforms to. That would be the better search criteria. -M< -- Martin Hannigan (c) 617-388-2663 VeriSign, Inc.

What kind of cable is this?
by Jonathan Nichols 07 Nov '04

07 Nov '04

http://homepage.mac.com/smurphy/PhotoAlbum28.html Guy I know in Canada came across a 7200 foot spool of what appears to be single-strand fibreoptic cable. He's trying to find out its properties, UV rating, etc. Any information available would be great. I Googled for the part numbers (so did he) and came up empty. Siecor appears to be "Corning Cable Systems" now and their website was unhelpful, to say the least. If anyone has any information or knows much about this stuff, could you drop me a note offlist?

Where can a person go to get a "one stop" WHOIS query for AS and prefix information instead of trying ARIN, then RIPE, etc? Thanks, Dan

what's a good way to annoy the hell out of somebody at chello.be?
by Paul Vixie 06 Nov '04

06 Nov '04

a customer of chello.be has been repeating a dns dynamic update against my zone every four minutes since october 20. chello's abuse reporting channel is no doubt full of spam reports. their noc no doubt doesn't care about end-user problems. i nmap'd the offending box: Starting nmap 3.50 ( http://www.insecure.org/nmap/ ) at 2004-11-05 17:24 GMT Interesting ports on cable-62-205-122-245.upc.chello.be (62.205.122.245): (The 1638 ports scanned but not shown below are in state: closed) PORT STATE SERVICE 9/tcp open discard 13/tcp open daytime 21/tcp open ftp 25/tcp open smtp 37/tcp filtered time 53/tcp open domain 111/tcp open rpcbind 113/tcp filtered auth 135/tcp filtered msrpc 137/tcp filtered netbios-ns 138/tcp filtered netbios-dgm 139/tcp filtered netbios-ssn 445/tcp filtered microsoft-ds 515/tcp open printer 548/tcp open afpovertcp 1024/tcp open kdm 1025/tcp open NFS-or-IIS 1026/tcp filtered LSA-or-nterm 8009/tcp open ajp13 8080/tcp open http-proxy 10000/tcp open snet-sensor-mgmt and i connected to every one of those services that i had a client for, and sent mail to the postmaster (using telnet and the @[] notation), but i think i have not done enough to set off any kind of intrusion detection systems. what's a socially acceptable way to be rude enough to make these people pay attention to me? i'm asking not just for this host -- i'm hoping there's a "community standard" i can follow, and recommend that others follow. the box is raw debian. in fact its hostname (according to its exim and bind) is "debian". i don't think anybody's reading its "postmaster" mailbox. i do not think there is any evil intent in the updates they won't stop sending me, but they're filling my logs and i don't want to firewall them.

Better block the internet in that case ;) I heared of BGP feeds that provide 'questionable prefixes' so that one can nicely nullroute those using that system. I still am of the opinion that only accepting verifyable PGP signed mail could slow spammers down a bit, then at least the spambot took the time of generating, distributing and letting people trust the spambots key. Maybe trow in some trust metric ala advogato!? Then again, the spambots will simply find the preconfigured key from an infected user and start using that, save passwords ole, at least one then knows the source it is coming from is really also able to sign it that way, thus most likely is the problem person, unless the virus of course redistributes the pgp keys using some nice p2p algo to other worms. (ohoh :) This would at least take away most of the virusses sending random sources. But getting everybody to do PGP-signed mail is asking the same thing as asking people to turn of sending html emails, A somewhat similar scheme does work for RIPE-db updates, but the people submitting there have probably some clue on how to configure their boxes and unfortunately we are of course talking about $lusers. Spam already lost it from virusses and the spam coming forth from misconfigured antivirus tools sending 'hi you send a virus' alike messages. Above setup should be able to work for closed communities like mailinglists where only a few number of people post, if you want to post, sign your message, mailinglist software could then verify the key and only pass it on if the member is subscribed and the signature is valid. A virus picking random addresses and sending to existing messages in the mailbox, thus having 'valid' source/dest combinations doesn't make much of chance then unless it figures out the pgp key and the password. Then again I just might be a ... http://www.rhyolite.com/anti-spam/you-might-be.html ;) BTW1: that because you quote above my complete message, my message becomes part of your signature and my mailer nicely ignores it ;) BTW2: Ooops... discussing spammy related things on NANOG....

Hi Charlie - We use JFFNMS here (http://www.jffnms.org/) We have it monitoring BGP with our 6 backbone providers, all of our T1's (300 or so), DSL lines, dedicated servers, backing up all of our router configs, talking to our F5s, pretty much everything you are asking for. We use it extensively to grab traps and notify my NOC of any problems. Overall I would say that it is monitoring over 15,000 connections and pieces of hardware. We have its bandwidth monitoring and tracking talking directly to our billing engine and allow our customers the ability to log into it and view all of their stats as well. We don't use it to monitor uptime as we utilize different hardware for that but my guess is that with some minor tweaking it could do that as well. Hope this helps.
