Good (cheap) 2000Mb/s solution?
by Deepak Jain 08 May '03

08 May '03

I need a good, cheap (its temporary) solution to run 2000mb/s over a single pair of multimode fiber (SX handoffs). I'd ideally like to put in two GEs, and get two out. I could use 10G gear, or OC48 gear, but I was hoping for something less pricey since this only has two run about 200ft between two buildings. Any suggestions? I will be glad to summarize for anyone who wants it. Thanks, Deepak Jain AiNET

Re: PMTU and Broken Servers
by Joe St Sauver 08 May '03

08 May '03

Hi Leo, #The tunnel between the tunnelboxes is a lower (1480) MTU. Originally #the user couldn't access some servers, turns out the firewall was #filtering ICMP Can't Fragment messages, preventing PMTU from working #in the server->user direction (tunnelbox1 would generate Can't #Fragement, firewall would filter). This is actually a more broadly present problem than you might think. I talked about this in the context of a jumbo frames presentation ("Practical Issues Associated with 9K MTUs") I did for the February NLANR/I2 Joint Techs in Miami; see: http://darkwing.uoregon.edu/~joe/jumbos/ (PDF and PowerPoint versions provided) #I find it slightly #(emphasis on the slightly) that someone would turn on PMTU discovery, #and then filter it out right in front of the boxes where they turned #it on. Different folks are probably driving the server network configuration and the firewall/border router configuration process. Disconnect is not inconceivable in that scenario by any means. #This is a new problem to me, but I'm sure people have run into it #before. Are the servers really that broken (PMTU enabled, ICMP #Can't Fragement filtered)? Yes, it is a huge issue potentially.

Who are you to tell them how to run their network, when you can't even keep your own network's SPAM problem under control? BCP4 documents a practice which is neither "Best" nor "Common". In fact, it's heavily flawed, and relies on the incorrect assumptions that there's somehow a shortage of IPv4 space, and ARIN is worthy of free hand-outs in the form of large blocks of IP space, with no monitary compensation offered to those who "surrender" them. Anyone who even considers following it needs to have their head examined. Erie Forge has done absolutely nothing wrong in this matter; their IP space is no more "jacked" than any other. >> "7.

It's been proven that many network operators represented on NANOG, who on the surface appear perfectly legitimate, run spamming operations or harbor known spammers behind closed doors. For this reason, everyone, including this ficticious "Gweep corporation" of yours must be regarded as black hat, until Kai Schlicting or the SPEWS maintainers are able to demonstrate otherwise. Vigilance is key here. If you've got an armed threat, you need an armed presence. >AfterBurner and the rest of the RCN >abuse team is widely respected as one of the best in the industry. "AfterBurner", LOL! If they're so respected, why are they incapable of demonstrating a bit of common sense and netiquite as posting with their real names instead of pseudonyms? How am I to take anyone seriously when they go by "AfterBurner"? This is the operational community you're addressing here, not the audience at a 2600 meeting. And you've failed to even comment on the URL I produced earlier, showing evidence of SPAM on RCN's network, some originating from RCN sales and support people. Concerned about your privacy?

Pakistan government orders ISP service level agreement
by Sean Donelan 07 May '03

07 May '03

Pakistan has been suffering a 40 day DOS attack, disrupting most of the International Internet service in the country. The Pakistan Government, Minister for IT & Telecom, has "directed" the Pakistan Telecommunications Corporation to sign service level agreements to ensure 99% Internet availability. Over 200 official(government?) websites have been inaccessible for over three weeks. http://www.paknews.com/main.php?id=5&date1=2003-05-05 "Within a period of five days, the body has been assigned to formulate a concrete strategy to stem the incidence of DoS attacks.. The committee will work on urgent basis and suggest short-term measures within two day."

Yet more hijacked space? - deru.net

Since were on the topic of hijacked ipspace, i find myself wondering about deru.net "Deru, the name you can trust, from people you can trust." - Quoted from www.deru.net Ok, so this is the name you can trust, from the people you can trust, right? Well then, why would it appear that Deru.net, the local ISP you can trust is using hijacked ip space?

Now the question at hand is, at which point did this hardware company become Deru.net, the Internet Service Provider you can trust? was this before, or after Penril Datability Networks Inc/Bay Networks/Access Beyond.? Did everyone decide to move to arizona and start an ISP? or is this just another example of IP hijacking that we all find ourselves taking a look at. Can deru.net provide documents that say they bought or were aquired by Datability Software Systems, Inc/Penril Datability Networks/Bay Networks/Access Beyond.?

Re: NNTP servers
by Joe St Sauver 07 May '03

07 May '03

Hi Drew, # Howdy, if this is off-topic I certainly apologize however I #believe that running an NNTP server is usually part of a 'network #operations' sphere of influence. Dunno about that, but I'll chime in a couple of ideas just because the volumes of NNTP traffic involved have gotten to the point where the traffic alone is probably operationally interesting, everything else aside. #I have a few basic questions. Does anyone #know off hand how much disk is needed for a fairly respectable NNTP server #for a full feed? Daily Usenet volumes are extremely sensitive to decisions with respect to carrying (or not carrying) even single groups. See, for example http://www.newsadmin.com/top100bytes.htm which shows that the top half dozen groups (by bytes posted) had daily volume running: Binary Newsgroup Bytes % Total ---------------------------------------------------------- 1 alt.binaries.dvdr 30,304,095,023 5.893 2 alt.binaries.cd.image.xbox 25,796,723,944 5.017 3 alt.binaries.dvd 19,428,583,576 3.778 4 alt.binaries.multimedia 17,783,671,185 3.459 5 alt.binaries.cd.image.games 15,303,064,035 2.976 6 alt.binaries.svcd 14,780,524,967 2.874 [commas added to byte counts for improved legibility] Yes, carrying or not carrying a single group can have a 30GB/day impact. Yes, daily traffic for a fullish feed *has* peaked in excess of 600GB and 3 million articles/day. If you want to carry "everything," you could multiply ~0.6TB/day times the number of day's retention you want to keep, however note that over time your retention will drift downward as volumes continue to increase. Also note that this is is just raw article storage space, and does not include space for article overview data, history files, etc. Daily Usenet volumes (in bytes) are also exceptionally sensitive to maximum article size, with the 80/20 rule roughly holding for byte traffic and article count (e.g., 80% of the articles by article count will require just 20% of the transfer bandwidth). If your goal is to live within a given bandwidth budget, or to efficiently utilize a particular size disk array, you can readily adjust your total article payload/day by dialing down the maximum article size you elect to accept. In case you doubt these volume stats, a couple of sites with publicly accessible daily traffic summaries include: http://nntp.abs.net/cyclone/stats/ http://informatie.wirehub.net/news/bambam/diablo.html http://newsfeed.media.kyoto-u.ac.jp/innreport/ I would note that most "full" feeds today really *AREN'T* full, however. #Also is IDE still too slow/unreliable for this type of #operation? I know back when we got our current server IDE was very slow it #has sped up a bit since then. Choice of file system, and storage methodology can be as or more critical than whether or not you're using IDE or SCSI. The days where traditional article-per-file spools in UFS file systems would work are definitely gone -- cyclical news file systems on top of ReiserFS are a popular recipe today. #The reason I am asking is because it has come #time for the old NNTP server to be buried somewhere in the mountains and for #me to procure a new one. Currently we are running a P3 600 /w about 200 GB #of storage on Solaris and Typhoon, the reason we are replacing this server #is for the poor performance and its abhorrent retention. If you're planning to work with a full feed, you won't regret getting as much CPU, memory, disk, and network connectivity as you can afford. I don't want to get into hardware/OS/server religious wars, so I'll skip any specifics here (although feel free to contact me offlist if you're interested in talking about some starting points for hardware options that seem to work okay).
