The only point I am trying to make is operational WRT the command structure of a NOC. Several of us here have built many of the large NOC's in operation of the Internet today and if you put us all in the same room we'd all agree that we already know how to build NOC's that respond and get the job done for the most part. It ain't that hard anymore. Question: Do people really think waking up Bob Parsons at 0400 is a good idea for a $9.00 domain only account? He already got a roughly ~$50.00 response with all the time he had GoDaddy on the phone and the out supervisor call. I think if Parkel does, he needs to sign up with VeriSign, UltraDNS, or anyone else who is running DNS assurance products. Note: Please refrain from inferring an endorsement for DNS assurance products. -M<

Problems connectivity GE on Foundry BigIron to Cisco 2950T
by Sam Stickland 15 Jan '06

15 Jan '06

Hi, I'm having a right mare trying to get a Foundry BigIron to connect up to a cisco 2950T, via Gigabit copper. The Foundry BigIron is using a cisco RJ45/copper GBIC that was pulled from a live cisco 6500, where it was working fine. The cisco 2950T has two fixed 10/100/1000 RJ45 ports. The cables between the equipment have been tested and are fine. The Foundry has three different types of the gigabit negiation modes: auto-gig Autonegotiation neg-full-auto Autonegotiation first, if failed try non-autonegotiation neg-off Non-autonegotiation I've tried all three, complete with all the other possibilities with the cisco 2950T (which has fixed full duplex operation, but can be set to 'speed auto' or 'speed 1000'). None of these combinations bring up the link. The cisco 2950 never gets a link light. The Foundry gets a link light regardless when it's mode is set to 'gig-default neg-off'. I'm at a bit of a loss to explain this. Does anyone know of any configuration issues that can explain this, or is it time to start swapping out hardware components? Sam

Hi, Matthew. ] Cisco Router and Security Device Manager (SDM) is installed on this device. ] This feature requires the one-time use of the username "cisco" ] with the password "cisco". Interesting. Is it limited to one-time use? Are the network login services (SSH, telnet, et al.) prevented from using this login and password? Thanks!

RE: Is my router owned? How would I know?
by Barry Greene (bgreene) 14 Jan '06

Here are some other new things (Cisco IOS specific): Login Security Enhancements. The Cisco IOS Login Enhancements feature allows users to better secure their Cisco IOS devices when creating a virtual connection, such as Telnet, secure shell (SSH), or HTTP. Thus, users can help slow down dictionary attacks and help protect their router from a possible denial-of-service (DoS) attack. http://www.cisco.com/en/US/products/sw/iosswrel/ps5207/products_feature_ guide09186a00801d1cb3.html Configuration Change Notification and Logging. Releases of Cisco IOS software prior to 12.3(4)T/12.2(25)S lack the ability to track the origin of changes to the running configuration. The only way to determine if a Cisco IOS software configuration has been changed is to pull the running and startup configurations offline and do a line-by-line comparison. This comparison will identify all the changes that have occurred between the two configurations, but it will not specify the sequence in which the changes occurred or the person responsible for the changes. The Configuration Change Notification and Logging (Configuration Logging) feature allows the tracking of configuration changes entered on a per-session and per-user basis by implementing a configuration log. The configuration log will track each configuration command that is applied, who applied the command, the parser return code for that command, and the time that the command was applied. This feature also adds a notification mechanism that sends asynchronous notifications to registered applications whenever the configuration log changes. http://www.cisco.com/en/US/products/sw/iosswrel/ps5207/products_feature_ guide09186a00801d1e81.html And then there is 'security passwords min-length'. If you set this to 6 more more, it would knock out 'cisco' as a possible password on the router. > -----Original Message----- > From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On > Behalf Of Rob Thomas > Sent: Thursday, January 12, 2006 10:19 AM > To: NANOG > Subject: Is my router owned?
