If you put your monitor on the other side of the broken link, external to your network, then pages directly to the cell provider will go through. So, if your T3 goes down, an external monitor that is not affected by the outage can send the page.

IANA IPv4 allocations and bogon update: 71/8, 72/8
by Stephen Gill 03 Aug '04

03 Aug '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, team. [ Apologies to those of you who receive this note in multiple forums. ] The numerous Team Cymru bogon projects have been updated as of 02 AUG 2004 to reflect the following IANA allocation made on 02 AUG 2004: 71/8 Aug 04 ARIN 72/8 Aug 04 ARIN IANA allocations change over time, so please check regularly to ensure you have the latest filters if you are not using the bogon BGP feed(s). We do announce updates to the bogon projects to sundry lists, such as the bogon-announce list. We can not stress this point strongly enough - these allocations change. If you do not adjust your filters, you will be unable to access perhaps large portions of the Internet. Worse yet, you may end up blocking access for people who transit through you. Please do not apply any filters or blocks to your network without carefully considering the ramifications of doing so. As a point of reference, the Team Cymru master Bogon Reference Page can be found here: <http://www.cymru.com/Bogons/> A quick summary of the documents and projects that have been updated include the following: HTTP The Bogon List - <http://www.cymru.com/Documents/bogon-list.html> The Text Bogon Lists - <http://www.cymru.com/Documents/bogon-bn-nonagg.txt> - <http://www.cymru.com/Documents/bogon-bn-agg.txt> Secure BIND Template - <http://www.cymru.com/Documents/secure-bind-template.html> Secure IOS Template (Cisco) - <http://www.cymru.com/Documents/secure-ios-template.html> Secure BGP Template (Cisco) - <http://www.cymru.com/Documents/secure-bgp-template.html> Secure JUNOS Template (Juniper) - <http://www.cymru.com/gillsr/documents/junos-template.htm> Secure JUNOS BGP Template (Juniper) - <http://www.cymru.com/gillsr/documents/junos-bgp-template.htm> Ingress Prefix Filter Templates, Loose and Strict (Cisco) - <ftp://ftp-eng.cisco.com/cons/isp/security/Ingress-Prefix-Filter-Templ ates/> Ingress Prefix Filter Template, Loose (Juniper) - <http://www.cymru.com/gillsr/documents/junos-isp-prefix-filter-loose.h tm> Ingress Prefix Filter Template, Strict (Juniper) - <http://www.cymru.com/gillsr/documents/junos-isp-prefix-filter-strict. htm> BGP Bogon route-server for AUTOMATED updates of bogon filters - All bogon route-server peers have already received the appropriate BGP prefix updates. - <http://www.cymru.com/BGP/bogon-rs.html> RADb fltr-unallocated fltr-martian fltr-bogons - <http://www.cymru.com/Bogons/index.html#radb> RIPE NCC fltr-unallocated fltr-martian fltr-bogons - <http://www.cymru.com/Bogons/index.html#ripe> DNS Bogon (bogons.cymru.com) zone - <http://www.cymru.com/Bogons/index.html#dns> Monitoring Bogon prefix monitoring - <http://www.cymru.com/BGP/robbgp-bogon.html> Bogus ASN monitoring - <http://www.cymru.com/BGP/asnbogusrep.html> Please feel free to contact Team Cymru <team-cymru(a)cymru.com> with any comments, questions, or concerns.

I cannot seem to reach an entire netblock. 168.100.0.0 (a block from Cloud9 Internet, a local ISP) is unreachable. Does anyone know of a major cut or problem somewhere? Thanks in advance. -- Charles Gagnon () ASCII ribbon campaign OTA LLC /\ against html mail 914-460-4055

Nagios is configured to use sms_client: http://www.smsclient.org/ Works great other than being a royal pain in the rear when a lot of things go down and dependencies are not set up in Nagios... I'll fix that one of these days :-) Mark Radabaugh Amplex

You could also have a dial-on-demand analog modem over a pots line that dials a competitor ;-) but overall gnokii is what makes the most sense because it has the less fate sharing: if a backhoe digs your data and phone at the same time, chances are that the GSM will still work.

SMS is ss7 based. You could buy a pair of combined linkset A links, buy an SMS gateway and communicate with it. Your best bet, IMHO, is dialing up and sending pages. There's a protocol..I forget.

Quick question about secondary addresses
by Dan Lockwood 03 Aug '04

03 Aug '04

I'm in a debate with a guy over the use of 'ip address x.x.x.x s.s.s.s secondary' on Cisco gear. I seem to remember reading that the use of secondary addresses is a bad idea, but I can't recall the details of why. Process switched? Can anyone offer a resource or more specific information? Thanks, Dan
