NTPv3 stratum-1 with MD5 availability
by John Kristoff 16 Jul '03

16 Jul '03

We're reworking our current NTP infrastructure and are looking for public NTP stratum-1 servers (we don't currently have the resources to run our own stratum-1 at this time) that are willing to allow one of our stratum-2's to get and distribute time from. We'd like to use MD5 authentication and so far I've had limited success in 1) just getting any response from nearby stratum-1's, but also 2) finding public stratum-1's that will do MD5. Before I start going down the list and bugging stratum-1 admins in other regional areas on David Mill's public list, is there anyone who operates or knows of a stratum-1 that will offer this service for us (and someone or someplace I can marginally validate the trusthworthiness of :-). Replies are probably best off-list unless you want to broadcast to the world that you offer such a service. Thanks in advance, John

IOS and SNMP question regarding 802.1q vlans on 7200.
by Ejay Hire 15 Jul '03

15 Jul '03

Hi all. I've got a 7206 in a remote collocation facility that's running dot1q back to the community switch. When MRTG's cfgmaker only finds the physical interface, not the vlan sub interfaces. The other devices in the network use ISL, and don't have this problem. Does anyone have recommendations or experiences on how to make this work? Thanks, Ejay Hire

I need a portable /24 not attached to any sub-domain or anything else subject to attack
by Henry Linneweh 15 Jul '03

15 Jul '03

I simply would like to borrow this /24 if you are not going to use in the near and distant future or ever for that matter. It can not be attached to any subdomain and or any or part of any routing table, this would most helpful in the development of methods to prevent ddos and dos. Thank you very much Henry R Linneweh

Funny VZ bounce
by Gerald 14 Jul '03

This isn't the first time I've seen this, but I've got to question the reasoning in putting a quota on your abuse e-mail address. Wonder if postmaster went over his limit too. If you've e-mailed Verizon abuse lately, I'm sure you've already seen this. G *** Begin Bounce *** This Message was undeliverable due to the following reason: The user(s) account is temporarily over quota. <abuse(a)verizon.net> Please reply to Postmaster(a)verizon.net if you feel this message to be in error.

Unique AS
by Adonaylo, Gabriel 14 Jul '03

14 Jul '03

Hello All, First of all, forgive my English writting please! I work for an Internet Carrier in Argentina which is in process of reorganizing its regional operations. We are also serving in other countries in South America. We currently have one AS per country and we are looking forward to migrate to a unique AS for all the organizations. Could anyone describe pros and cons of having a unique AS for this kind of networks rather than having one AS for each country. Regardless of the cons, we are facing migration process anytime soon, so I would appreciate very much to get more pros than cons to include in my papers which are almost finished! I would also be glad if you share your experience about this migration process. That is the real value of your answers. Thanks for your time. Regards, Gabriel.
