NANOG Board Announcement
by Steven Feldman 10 Aug '11

10 Aug '11

I am sad to announce that Robert Seastrom has resigned from the NewNOG Board of Directors, effective yesterday. Rob has served on the Steering Committee, transition team, and the board for the past three years, and has provided valuable insight and assistance throughout the transition of NANOG to a standalone organization. I thank Rob for his service to the community, and look forward to his continued participation as a member. Since this creates a vacancy on the board with more than two months remaining until the next election, the Bylaws require the remaining board members to appoint a temporary replacement to serve until the election. At that time, a permanent replacement will be elected to fill the remainder of Rob's term, which ends in October 2012. Accordingly, the board has selected Michael K. Smith to fill the vacant position between now and the October Election. Mike has been serving as Communications Committee chair for a few years, as well as assisting with budgeting, technical planning, and many other behind-the-scenes tasks during the transition. Please join me in thanking Rob for his service, and in welcoming Mike to the board. Thanks, Steve Feldman, chair

I'm missing 2 bytes (GRE implementation)
by Franck Martin 10 Aug '11

10 Aug '11

I'm using a GRE IPv4 tunnel between a cisco and linux machines I did some packet capture, and saw that my MTU was 1418, but the cisco was sending TCP packet with a MSS of 1380. This created a bunch of issues. When I told the cisco box to use a MSS of 1378 everything starting to work fine. So why Cisco is off by 2 Bytes? Does the GRE implementation on Linux uses 2 extra bytes compared to Cisco (or vice versa)?

ISP support for use of 4-byte ASNs in peering
by John Curran 09 Aug '11

09 Aug '11

Folks - Is there a public list somewhere of service providers that do not support 4-byte autonomous system numbers when peering? (if not, should there be one?) At ARIN, we are still having parties returning 4-byte ASN's (seeking 2-byte instead), indicating that the 4-byte ones are not sufficiently accepted in peering to be usable. This is obviously a less than desirable situation, and it appears that it is not trending towards resolution at this time. Thoughts? /John John Curran President and CEO ARIN

Re: I'm missing 2 bytes (GRE implementation)
by Stefan Fouant 09 Aug '11

Everything from checksums, keys, and sequence numbers is optional. The only required fields IIRC amount to 2 bytes of overhead. Sounds like they both interpret what should be included in the GRE header slightly differently.

not operational -- call for nominations for ARIN council & board
by Paul Vixie 09 Aug '11

09 Aug '11

gentlefolk, ARIN is the community's self-generated steward for internet numbering resources (ip addresses and autonomous system numbers) and it is governed by volunteers from the community who serve on its advisory council and executive board. every year ARIN holds an election to fill or renew several expiring terms. candidates need not be ARIN members. please see <https://www.arin.net/announcements/2011/20110725_elec.html> and think about whether who you can nominate or whether you can self- nominate. paul vixie chairman, 2011 arin nomcom
