http://www.nanog.org/postel-scholarship.html Overview NANOG and ARIN have been been unique and successful cooperative fora for Internet builders in North America and other parts of the world. Senior practitioners from around the world contribute their time to NANOG and ARIN as presenters, teachers and trainers, to produce consistent non-commercial conferences of high-quality. Since 2007, the generosity of an anonymous donor and the administration of the Internet Society, have allowed NANOG and ARIN to provide financial support to a person from a developing country to participate in the October joint NANOG/ARIN meeting. The Postel Network Operator's Scholarship Committee cordially invite suitable applicants to apply for fellowship funding to participate in the October 2008 joint NANOG/ARIN meeting. Target Audience The Postel Network Operator's Scholarship targets personnel from developing countries who are actively involved in Internet development, in any of the following roles: * Engineers (Network Builders) * Operational and Infrastructure Support Personnel * Educators, Teachers, and Trainers Award Package Successful applicants will be provided with transportation to and from the meetings and a reasonable (local host standard) allowance for food and accommodation. In addition all fees for participation in the conferences, tutorials, and social events will be waived. The final grant size is determined according to final costs and available funding, and will be advised to successful applicants. Criteria for Selection The Postel Network Operator's Scholarship Committee will select the fellow according to following criteria. * Membership in the Target Audience listed above * Residency in a developing country * Demonstrated ability to utilize the experiences gained from NANOG/ARIN within their country, region, ... * Evaluation of an abstract of a presentation to be given at the meeting.

mtu mis-match
Hi I have this problem about mtu mismatch Some DSL clients, some are working fine. (browsing...ping ...) Some DSL clients have this problem they can't browse the sites. they can ssh the host but couldn't run the command in the shell prompt ping packet are working fine (no packet lost) Why? but I still don't know why mtu can cause this problem Thank you for your help Never miss a thing.

If are using a Linux box as a router, then you can set the MTU of any interface with the ifconfig command. Jon K. -- Jon R.

Ping packets, unless you specifically use a larger packet size, are usually pretty small. Try running ping tests with a larger packet size, say, 1495 bytes, and see if those fail. HTTP, SSH, etc, can easily (and often do) generate packets up to the maximum segment size. That's why MTU mismatches can seem to affect some types of traffic but not others. The 'lowest common denominator' for MTUs is often 1500 bytes, but protocols that need to wrap or tunnel existing packets (GRE, PPPoE, IPSEC, etc) impose some overhead of their own. Unless the MTU or TCP maximum segment size of the original traffic is reduced a bit, the tunneled packets will need to be fragmented for transport across the network. This can lead to performance problems like the ones you're seeing. The magic number for an MTU on PPPoE DSL is 1492 bytes, based on past DSL aggregation work I've done. jms
Re: do you know how to dump packet to see vlan info
You can use the 8021q module in linux, and the vlan tools to run an interface as a dot1q trunk. I'm not sure off-hand about the other distributions, but under Debian you just need the 'vlan' package. modprobe 8021q ifconfig eth1 up vconfig add eth1 vlan id ifconfig eth1.vlan id ip address netmask netmask Configure your switch port to trunk mode, tag your vlans onto it, et voila. This will give you a presence in as many broadcast domains as you decide to tag. - billn On Wed, 19 Mar 2008, Jon R.
