Problems Communicating with Network Solutions

20 Aug '08

Is there anyone at XO or Network Solutions that can help me with a little problem we're having? About two days ago we lost the ability to pass all traffic with Network Solutions hosted email and their main website from our main office. It keeps dying at a router in DC. Here's a trace from our Chicago office: Tracing route to 205.178.149.7 over a maximum of 30 hops 1 <1 ms <1 ms <1 ms 38.98.154.1 2 1 ms 1 ms 2 ms fa0-7.na01.b002327-0.ord01.atlas.cogentco.com [38.99.215.81] 3 <1 ms <1 ms 1 ms gi0-7.3542.core01.ord01.atlas.cogentco.com [66.250.11.189] 4 <1 ms 1 ms <1 ms te4-1.mpd01.ord01.atlas.cogentco.com [154.54.1.98] 5 1 ms 1 ms 1 ms vl3488.mpd01.ord03.atlas.cogentco.com [154.54.5.26] 6 <1 ms <1 ms <1 ms xo.ord03.atlas.cogentco.com [154.54.12.230] 7 2 ms 1 ms 1 ms te-3-1-0.rar3.chicago-il.us.xo.net [65.106.1.42] 8 4 ms 1 ms 1 ms ge7-0-0d0.rar1.chicago-il.us.xo.net [65.106.1.41] 9 28 ms 27 ms 28 ms p6-0-0.rar2.washington-dc.us.xo.net [65.106.0.46] 10 * * * Request timed out.

RE: IP Fragmentation (correction)
by John Lee 20 Aug '08

20 Aug '08

Correction. TTL needs to be set to sufficiently large number of hops to allow the packet to get through the number of hops and the timers need to be set to allow the packet to transit the network and the low speed links before timing out and retransmitting the packet. John (ISDN) Lee ________________________________________ From: John Lee [john(a)internetassociatesllc.com] Sent: Wednesday, August 20, 2008 2:10 PM To: Glen Kent; OPS Gurus Subject: RE: IP Fragmentation Glen, With the v4 networks that I have worked on in the past, they did not do end to end MTU discovery before sending packets. The TTL had to be set appropriately so that if you had low speed links, for example, the packet and response would get through in time. On our DS3 (T3) and OC-3c packet links we did 4k, 9k, and 16k packet sizes for video and file transfers. At the other end of the spectrum are civilian and military systems with tactical links, both wired and radio, with low bit rates and header compression on IP and TCP packets. Speeds range from 300 -9,600 bps, 16k, 32k, 64k and Nx64k bps links that can do packet fragmentation and adding proprietary ECC codes for the radio links. Some systems strip the IP packet and use standard or non-standard link layer protocols across the mediums. Some of these systems are store and forward so that the computer/router that is connected to the low speed link will ack the packet for the high speed network connection and buffer it up until it can be sent on the lower speed system. IMHO current IPv6 protocols ignore the lower end segment by specifying the lowest MTU for the circuit be the MTU for the entire circuit and not allow fragmentation. I do not see this as an efficient use of high speed network resources and local link management can handle fragmentation just fine. John (ISDN) Lee A slightly different History Channel. ________________________________________ From: Glen Kent [glen.kent(a)gmail.com] Sent: Wednesday, August 20, 2008 12:13 PM To: OPS Gurus Subject: IP Fragmentation Hi, Do transit routers in the wild actually get to do IP fragmentation these days? I was wondering if routers actually do it or not, because the source usually discovers the path MTU and sends its data with the least supported MTU. Is this true? Even if this is, then this would break for multicast IP. The source cannot determine which receivers would get interested in the traffic and what capacities the links connecting them would support. So, a source would send IP packets with some size, and theres a chance that one of the routers *may* have to fragment those IP packets before passing it on to the next router. I would wager that the vendors and operators would want to avoid IP fragmentation since thats usually done in SW (unless you've got a very powerful ASIC or your box is NP based). Thanks, Glen

uTorrent, IPv6
by Nathan Ward 20 Aug '08

20 Aug '08

Sit up and pay attention, even if you don't now run IPv6, or even if you don't ever intend to run IPv6. Your off-net bandwidth is going to increase, unless you put some relays in. As a friend of mine just said to me: "Welcome to your v6-enabled transit network, whether you like it or not ;-)". uTorrent 1.8 is out, as of Aug 9. uTorrent actively enables IPv6 on XP SP2 and Vista machines in the install process (by default, it can be turned off). IPv6 is turned on, on lots of PCs. uTorrent does DHT, so that uTorrent users will talk to eachother to exchange peers - IPv6 does not require tracker support. uTorrent (as far as I understand) knows how to set IPV6_PROTECTION_LEVEL appropriately on sockets, so that Teredo is actually used. What does this mean? It means that many uTorrent end users will have Teredo addresses, and many will have 6to4 addresses. As we roll out IPv6 globally, more and more uTorrent users will have non-tunnelled IPv6 addresses. uTorrent users move **LOTS** of data. This means relay load. There are very few 6to4 relays around the world. There are fewer Teredo relays. If you run a network today and do not have 6to4 and Teredo relays, traffic between a 6to4 end user and a Teredo end user will go off-net. That costs you money. So, if you run a network today, deploy 6to4 and Teredo relays, regardless of whether you have customer facing IPv6 or not. If you serve IPv6 content, you are already running Teredo and 6to4 relays, so that Windows Vista users get near to IPv4-speed access to your IPv6 content, right? Right... Azureus does IPv6 now, but does not turn on IPv6, and does not set the IPV6_PROTECTION_LEVEL (as far as I understand), so Teredo is not used. Windows uses 6to4 if you have a non-RFC1918 address, and it uses Teredo if you do not (typically, this means you are behind NAT). With the huge amount of end users behind NAT, this means that uTorrent will have a much wider effect than Azureus has had. Running a relay *does not* mean that people outside your network can use it. - Who uses your 6to4 relay is controlled by how far you advertise the well known IPv4 and IPv6 prefixes. - Your Teredo relay is used only by Teredo clients trying to get to your non-Teredo connected users (ie your 6to4 or natively connected users). 6to4 relays can be Cisco boxes, Juniper NetScreen, FreeBSD, Linux, etc. OpenBSD does not have 6to4 support. Teredo relays can be Windows boxes, or Linux/FreeBSD/etc. boxes running `Miredo'. I have pre-built FreeBSD images that run both 6to4 and Teredo relays, and can talk BGP to your network. They are about 30MB, so will run on a compact flash card, and will happily run on anything from a 133Mhz 468 (ie. Soekris net4501) through to whatever top of the line server you have. They can also optionally do this "Tui" thing, which uses 6to4 and BGP to build direct IPv6 over IPv4 tunnels to everyone else with one of these boxes, without you having to configure each tunnel manually - I have some central route-servers. Optional, experimental, YMMV, etc. Thankfully, both Teredo and 6to4 use anycast for relay discovery, so if you have load problems you can deploy more of these for the cost of a server. As per usual, I'm giving it away free, see the following URL, or contact me off list: http://www.braintrust.co.nz/tui/ If you don't care about the "Tui" stuff, ignore those parts of the document, the rest will work just fine. ps. I'm looking at packet dumps of things right now, captured from torrent clients from the last wee while. I'll be rambling about this and pointing at pretty graphs in about a week at APNIC26. -- Nathan Ward

20 Aug '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greetings, I am looking at deploying an open source CA/PKI for a client. It would be only for internal users and systems. It would have to manage a few hundred certificates against the organization's self-signed root cert. It would be installed on a CentOS 5.x platform. I have looked at OpenCA and Dogtag. Any other packages I should look at? Does anyone have any opinions as to the pros and cons of either of these packages or thoughts/comments/experience with other similar packages? I would especially be interested in your experience with building / installing the package and your opinion of the documentation available. TIA for your help! Jon Kibler - -- Jon R.

Smallest netblock that providers will accept?
by Mike Lyon 19 Aug '08

19 Aug '08

Hello All, I am curious as to the routing polices of the bigger providers such as ATT, L3, Internap, Qwest, Etc Etc... Is there a standard size netblock that these providers will accept? For instance, if customer "A" gets a /22 from ARIN and his upstream provider is ATT and L3, what would the smallest block be that those providers would accept from customer "A"? Would they accept something as small as a /24? Thanks, Mike

RouterOS performance?
by William Pitcock 19 Aug '08

19 Aug '08

Hi, We're looking at using Mikrotik's RouterOS for some some sort of software routing solution as part of our network in combination with supervised layer3 switching doing most likely some sort of limited BGP. Does anyone else here run it? Is it any good? Is it better than e.g. vyatta? If RouterOS and Vyatta both suck, is there any decent software routing solution? Our network is small (4 /24s) and we only need to push roughly 1-2gbit at the moment. Experiences with both would be appreciated. Thanks! William

RE: SLAAC(autoconfig) vs DHCPv6 vs IP Address Lifecycle Management
by John Lee 18 Aug '08

Scott, There are solutions that support both static, quasi-static, also driving DHCPv6 servers and Dynamic DNS updates. There are networks that have deployed IPal to automate and consolidate their IPv4 and IPv6 block allocations and interface assignments. Router Prefix delegation, SLAAC and DHCPv6 were implemented to have a more automated method of IPv6 address assignments because of the large potential number of IPv6 addresses to be assigned in a next generation network. IPal does address block assignments for Prefix delegation, SLAAC and DHCPv6 support. It does IPv6 interface assignments of /64 EUI-64, /64 random, /126, /127 and /128 and generate the Dynamic DNS updates for those assignments. E-mail me off list if you want any additional information. John (ISDN) Lee ________________________________________ From: Howard C.

I submit that if you use dynamic assignment of any sort, you really have to have DNS dynamic update, so you can use a known name to query the function that's indexed by address. Otherwise, static addresses become rather necessary if you want to check a resource. This was especially a question when L2 was "in" and routing was out: how do you ping a MAC address?
