megapath.net dns
by Len Rose 16 Jul '03

16 Jul '03

Can someone with a clue at megapath.net PLEASE fix your dns. I've been sending mail to noc@ for the last 24 hours but all I get are auto responder messages. Your forward zones don't match your reverse zones for mia.megapath.net and 74.33.69.in-addr.arpa zones. You are causing denial of service for your customers.

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
