VZ Maryland contact needed
by William Warren 27 Apr '06

27 Apr '06

I have a client who's been offline all day. The dsl line is fine and their modem and firewall are also fine but data is not making it to them. All traffic to midatlantictime.net seems to get hung up at 130.81.10.226. I have tried from California, and two locations in Maryland and Texas. Sincerely, William Warren -- My "Foundation" verse: Isa 54:17 No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the LORD, and their righteousness is of me, saith the LORD.

recommendations regarding IPS
by Hegger, Stefan 01 Apr '06

01 Apr '06

Hi, hope not bothering you but I'm looking for some experiences with IPS systems. There are several vendors but is there a recommandation or some tests? As Service provider we need a system which handles the scanning in hardware and it should work as a layer2 bridge (no IP).

"Bad bgp identifier"
by Joe Maimon 31 Mar '06

31 Mar '06

4271 specifies that bgp identifier must be a valid unicast ip address So what is the larget 32 bit value expressed as a dotted quad that meets this requirement? Is it the last address in class c? class e? Can 255.x.x.x be used? Do all vendors implement this? I understand that draft-ietf-idr-bgp-identifier-06.txt does away with the above requirements. Is this something I should ask vendors if they will support it? Thanks, Joe

Rate-Limiting.
by Robert Sherrard 31 Mar '06

31 Mar '06

I've got a situation in which I'd like to rate limit a few servers that hang off of my 6590's... it appears that this can only be done on a layer 3 interface. These servers however aren't, they simply on a switch port / access. Aside from hard setting the l2 interface to 10mbit, can anyone think of another creative way to do this? Is one option moving these servers into a separate VLAN, then rate-limiting from there? Rob

Peering Issues with Global Crossing and SBC?
by Elijah Savage 31 Mar '06

31 Mar '06

All, I have well over 150 vpn customers but this past week I have had 7 customers ipsec tunnels constantly bouncing all day. The common ground for all 7 of these customers are traversing the SBC and Global Crossing links you see below, the ultimate common ground being 64.208.110.29. 9 151.164.191.134 16 msec 16 msec 16 msec 10 64.208.110.29 16 msec 16 msec 16 msec 9 151.164.40.49 16 msec 16 msec 16 msec 10 64.208.110.29 12 msec 20 msec 12 msec When tracing to these 7 customers all 7 hit one or the other of the trace's you see above. I have opened a ticket with SBC but no answer from them yet. All of the other customers have been very stable and of course non of the other customers traverse either of these links either. Anyone from Global Crossing or SBC that could contact me off list or lend a hand it would greatly appreciate it.

Even more interesting is how it got DNS name resolution on that address. Best available evidence indicates that _that_ header line is a total fabrication. As I recall, the header added by the destination system showed receipt from a yahoo machine (and a valid IP address, belonging to yahoo). It's possible that yahoo's auto-parsing got misled by the bogus header shown above. > > --==_Exmh_1143669323_3096P > Content-Type: application/pgp-signature > > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.2.2 (GNU/Linux) > Comment: Exmh version 2.5 07/13/2001 > > iD8DBQFEKwJLcC3lWbTT17ARAhcbAKDYpN/L2fVwYu9w2E4jG1P+knnPFwCdEliY > YSY/cunFfCJoJ8zky9YhYP8= > =qdCE > -----END PGP SIGNATURE----- > > --==_Exmh_1143669323_3096P-- >

Have Yahoo! gone pink?
by abuse＠cabal.org.uk 30 Mar '06

30 Mar '06

[I'm wearing my personal hat here.] I'm getting a *flood* of spam coming in from Yahoo! mailservers, both to my personal and work addresses. It seems that Yahoo! don't care. Here's the response to me piping a sample one through Spamcop: http://abuse.mooli.org.uk/yahoospam Yahoo claim "After investigation, we have determined that this email message did not originate from the Yahoo! Mail system. It appears that the sender of this message forged the header information to give the impression that it came from the Yahoo! Mail system." The spam headers claim otherwise: Received: from mrout3.yahoo.com ([216.145.54.173]) by relay-1.mail.uksolutions.net with esmtp (Exim 4.50) id 1FJbCW-0002Ag-IV for sales(a)uksolutions.co.uk; Wed, 15 Mar 2006 18:58:29 +0000 As does DNS and whois: abuse@mooli:~$ host 216.145.54.173 173.54.145.216.in-addr.arpa domain name pointer mrout3.yahoo.com. abuse@mooli:~$ host mrout3.yahoo.com mrout3.yahoo.com has address 216.145.54.173 abuse@mooli:~$ whois 216.145.54.173 OrgName: Yahoo! Inc. OrgID: YAHOOI-2 Address: 701 First Avenue City: Sunnyvale StateProv: CA PostalCode: 94089 Country: US [etc] Doing double-DNS lookups of the IP addresses on other spams also give yahoo.com hostnames, and they're typically in DNSBLs for being sources of spam and a useless abuse address. So, which IP blocks shall I null-route then? Or is there anybody here from Yahoo! with a clue? (OK, you can all stop laughing now.) -- PGP key ID E85DC776 - finger abuse(a)mooli.org.uk for full key

Backbone Monitoring Tools
by Ashe Canvar 29 Mar '06

29 Mar '06

Hi All, I want a simple backbone monitor for my 5 datacenters. My "backbone" consists of redundant IPSEC/GRE tunnnels. At the very least I want to ping, traceroute and transfer a small file every few minutes over all IPSEC links. I am sure there are products that do this already, but I am having a hard time finding any. The display format should be noc-friendly. A basic grid with green/red status indicators at the least. Geographical maps a plus. Do most of you use a home grown tool for this monitoring and alerting ? Regards, Ashe
