Re: MRTG [7:64133]
Here - http://people.ee.ethz.ch/~oetiker/webtools/mrtg/ Almost everything you need to know can be found there. The comp.dcom.net-management newsgroup is a good forum for getting it set up the way you want it. Both MRTG and RRD Tool (comes with MRTG). If you want to run it on a Windows server, you might want to check this out too. Its the Win NT guide to MRTG. http://people.ee.ethz.ch/~oetiker/webtools/mrtg/nt-guide.html http://www.activestate.com is a good source for Win32 version of Perl (needed for MRTG). You can still get slightly older version of their code, up through build 522, for free from: ftp://ftp.activestate.com/ActivePerl/Windows/5.005/Intel/ Its not the newest code out there but its free and it works just fine. Possibly more stable. FYI, search engines like google are a good place to look for info like this. Faster than asking. Hope this helps!

I doubt anyone uses half-duplex on Gigabit Ethernet, so this may be a clueless suggestion. However, that's the symptoms you would get. The side set to half would sense someone else sending while it was sending, stop, backoff and try again. The result of the thwarted transmission would be a runt with an FCS at the recipient. Since you replaced the fiber already, I guess you better start swapping hardware. But it's really hard to tell which side to replace. The sender could be sending bad data. I think that's more likely than the recipient having some problem with receiving the data and reporting FCSs. So I would start on the sender (the one not reporting errors, despite possibly being the culprit.) Are there any media filters or other components in this link that could be causing a problem??

RE: NAT order of operation [7:64037]
I had a look at the link, and this is the flow for inside-outside: If IPSec then check input access list decryption - for CET (Cisco Encryption Technology) or IPSec check input access list check input rate limits input accounting policy routing routing redirect to web cache NAT inside to outside (local to global translation) crypto (check map and mark for encryption) check output access list inspect (Context-based Access Control (CBAC)) TCP intercept encryption It makes sense to me to route first and NAT later, because until the router has performed the routing function, it can't know what interface to send the packet out. Once it knows the interface to send the packet out, it will know if NAT is required or not, and no further routing decisions are required. For outside-inside, this is the flow: If IPSec then check input access list decryption - for CET or IPSec check input access list check input rate limits input accounting NAT outside to inside (global to local translation) policy routing routing redirect to web cache crypto (check map and mark for encryption) check output access list inspect CBAC TCP intercept Encryption The router must perform NAT first, so that it will know the real destination address, and then it can make a routing decision based on the real destination address. So a very simplified (some detail left out) example would be a simple NAT to the internet for internal traffic such as this: Internal_PC(192.168.1.100)--(192.168.1.1 int e0)Router(int e1 217.217.217.217)--Internet Lets say that the router is performing NAT on all outbound traffic so that it appears to come from IP address 217.217.217.217. Lets pretend the PC is sending an HTTP request to a website (and that it has already performed a DNS lookup etc). 1.The PC will send an HTTP request for the website address (1.2.3.4). 2.The HTTP packet will be received by the router on INT e0. 3.The router will look at the destination address of the packet, realise that it is not on the local subnet, so it will look in it's routing tables for where to send the packet. 4.In our example the router will only have one route, which is a default to the Internet. 5.The router will therefore send the packet out it's INT e1 interface, but it will change the source address to be 217.217.217.217. This is the route first then NAT behaviour in your original question. Lets say that things are good today so the HTTP request made it to the web server, and the reply is coming back. 1.The router will receive the packet on it's external interface (INT e1) with a destination address of 217.217.217.217. 2.The router will realise that this is return traffic for the request that came out, so will NAT the packet back, changing the destination address back to 182.168.1.100, then look in it's routing tables to see where to send the packet. 3.It will realise that 192.168.1.100 is directly connected, so it will transmit the packet out it's INT e0 interface. I know I have simplified the process a lot and left some detail out, but that should explain why the flows are different depending on which way the traffic is going.

PIX-Checkpoin (was RE: Cat4006 - Prompt [7:63984]) [7:64144]
I replaced a couple of Checkpoint boxes that were handling about 700 concurrent inbound connections (trading system). The Checkpoint boxes (I think one was a PIII 500, the other a dual PIII 700) both PC's, handled it easy, no real CPU load, and they only need about 192MB RAM, 256 MAX. The PIX boxes (515e) show about the same amount of load. Is yours a 515 or a 515e? I think even a 515 would handle it easily. Were you terminating any VPN's etc? Whilst I prefer the PIX over Checkpoint on a server or PC, earlier PIX versions have (IMHO) some major limitations compared to Checkpoint, such as port translation (incoming port 25 send it to port 2500) which were not available until later versions. For what you need, I would certainly ditch the Checkpoint box and put the PIX in. What version of the OS is on it?

Re: Howto log failed login attempts? [7:64146]
Hi, the solution to this is the Cisco Security Server ACS. If you authenticate the users via this AAA Server it will log the successful and failed attempts. One server will do it for all routers and switches on the network. AAA means authentication, authorisation and accounting. This means you can define WHO can do WHAT and log WHEN they did it. This can include all commands entered on a router console with date and time. You find more information in the Cisco BCRAN taining course and the Remote access books. The ACS server is also part of Wireless LAN and other security solutions and VoIP accounting.

Re: Who likes BGP? [7:64123]
Isn't it standard practice for two entities, when setting up a peering, transit, or partial transit relationship, to agree on what routes will be sent over the links and then develop route filters on each side accordingly? If this is done properly, then a misconfiguration on one side should not impact folks upstream or peering, no? Of course, if misconfiguration happens at multiple levels, then damage might affect multiple levels. Is there ever a time when one can't setup predefined routing filters on an eBGP connection because the set of advertisements expected over the link would be unknown?

Re: Who likes BGP? [7:64123]
That's actually an accurate statement. From the White House's 'National Strategy to Secure Cyberspace', "(iii) Border Gateway Protocol. Of the many routing protocols in use within the Internet, the Border Gateway Protocol (BGP) is at greatest risk of being the target of attacks designed to disrupt or degrade service on a large scale." BGP, along with IP and DNS were identified in their document as three "key protocols" whose security and reliability are "Essential to the security of the Internet infrastructure." There has been a significant amount of work/discussion over the last few years to find ways to secure BGP so that some malicious/incompetent BGP-speaker couldn't create substantial black holes in the internet. As there is no global standard for using the Routing Registries, or any other registry-like entity, there is no global method in place for validating an announcer's authority for an AS, nor a prefix. Of course, like nearly anything else in our industry, there are a number of schools of thought on the Best Way (tm). There is also a new iteration of this discussion over on NANOG, I'm sure it will turn into yet another entertaining thread. -jm - Original Message - From: "Amazing" To: Sent: Friday, February 28, 2003 9:30 PM Subject: Re: Who likes BGP?

RE: Who likes BGP? [7:64132]
In my uneducated opinion, it seems to me like there are much larger concerns out there than BGP security. I say uneducated because I haven't worked for an ISP, nor have I worked for any other organization that would run BGP. My BGP experience consists of reading and lab work, that's it. I'm a Cisco Network Academy instructor, and the majority of my experience is from lab work and consulting. I'm teaching my first CCNP Routing class starting next week, so any input from those in the know would be appreciated. Hell, I'll appreciate input from those not in the know, I'm not picky... just don't expect me to take it as gospel truth. When I tell a router to peer with another BGP speaker, I can put restrictions on it. I can tell it what AS paths I'll accept from that peer, and what prefixes I'll accept from that peer. If I'm an ISP peering with a customer who has the class C network 210.5.5.0 assigned to them, do I not have a responsibility to configure my BGP router to ignore any BGP advertisements from that customer that are not advertising 210.5.5.0? I know that no one is going to hold me to it, it's not like the IETF has a squad of mercenaries who are going to kick the door in and check my configs, but doesn't that responsibility fall to both the customer and the ISP? Sorry if I'm off base here, but that's my basic understanding of how things work; the customer has a responsibility to only advertise their networks, and the ISP has a responsibility to only accept advertisements for that customer's networks. Does the same relationship exist among ISPs, or do things get too complex to filter updates at that point? It seems like the "security hole" in BGP is the human that configures a BGP router to accept any route it gets. Thoughts?

RE: Clock rate 64000 = Bandwidth 64000 - ? [7:64147]
Yes, in order for OSPF or EIGRP to have a more precise computation of costs and metrics, you should match the bandwidth with the port speed. However, if this is frame relay, you may want to match the bandwidth with the link's CIR.

Clocking (on the DCE side) specifies the bandwidth of a link while the 'bandwidth' statement is used for calculating routing netrics, the 'show int' load counter, etc. I can think of a few reasons why IOS doesn't just use the clocked amount as the bandwidth statement: - some interfaces (namely subinterfaces - ATM VCs, Frame VCs, etc) don't get a clock per se, but still need a concept of bandwidth. - A dodgy hack to allow people to easily modify routing metrics. - The DCE device may provide a clock that is higher than the actual link speed. A good example is an Async interface with a modem - the speed between the router and modem is 115Kbit, but the modem may only connect at 56Kbit.

I think the article is referring to the AS 7007 incident (a "small Virginia ISP", and simple digital signatures would not have prevented that. Requiring use of a routing registry and generating acceptance policy from validity-checked registry information is probably a much stronger technique. AS 7007 would have been preventable with prefix-limit.

Most clueful providers won't accept ANYTHING that comes from BGP peers, other than perhaps major default-free providers. In any case, there are other safety mechanisms than validating BGP updates themselves. I'm really unimpressed with this article.

Re: Howto log failed login attempts? [7:64146]
I don't know if this is doable since you are doing it locally. My advice to you is that this is not a scalable solution. What really want is TACACS+ server. If you are "cheap" like myself, you can build your own tacacs+ server running on an Intel 486 machine with 32MB of RAM with the OS being linux or FreeBSD. The tacacs server source code is located at ftp://ftp-eng.cisco.com/pub/tacacs If you are unix "illiterated", then you have to shell out money for Cisco ACS running on Winblows 2k Server platform (it sucks by the way). The tacacs+ server will let you do Authentication, Authorization and Accounting (logging successful and unsuccessful login attempts) and most important of all, it is scalable.

Re: Who likes BGP? [7:64132]
I agree with the part that there are many human related problems with BGP configs and policies implementations. But that's the case with other protocols as well. In BGP's case it's probably showing more of people's carelesness or misunderstanding of the working of the protocol since as you mentioned there are rare instances of protocol implementations besides the Internet. All the things you can implement facing the customer are fine and dandy, you can protect yourself and the customer has to adhere to certain policies as well. I think there is a problem with the scope of some networks, if you have to deal with filtering and such of hundreds or thousands of prefixes then you will see there is a good chance for mistakes. This is probably even more a case with inter-provider peerings, where you are really limited to what you can do as the work load on you would be quite substantial. Even if you did the proper work, there are cases for updates and revisiting where you can run into additional problems. All in all, I don't think the problem is with the protocol, it's the diveristy of the networks that need to be supported, lack of consistent information and obviously the human factor.

CPU and memory usage on Pix firewall VPN setup with PFS [7:64169]
Hi, I have 10 different VPN tunnels from my Pix520 firewall (500Mhz PIII and 256MB of RAM) to other Firewalls (Pix and Checkpoint) and Cisco VPN Concentrators. At the moment, all of the tunnels are using 3des, sha and DH group 2 in phase 1. In phase 2, I use 3des and sha1. For security purposes, I would like to add Perfect Forward Secrecy (PFS) to all tunnels. However, I am concerned with the CPU load and memory resources on the pix520. This pix520 firewall will also be used to protect your company web and mail servers (DMZ1). The Oracle database servers are located on another DMZ segment (DMZ2) Furthermore, it will also be used to protect our internal network and as well as accessing the Internet. We don't have the budget to purchase any equipments, not even the VPN Acceleration Card (VAC). The pix is connected to a SDSL router (1.5Mbps up/down). During normal business hours, I notice that the cpu usage is about 40% and memory is usage is about 80MB. In the evening when there is a lot of backing up going on (the backup server is located on the internal network and it backs up all the web mail and database servers). While the servers are being backup, some database replication also takes place between the VPNs. I took a sample of that and the traffic on the "outside" interface maxes out at 1.5 mbps and the traffic between the "inside" and dmz is running at about 60mbps. The cpu usage is about 55% and the memory usage is about 85MB. My question is: should I enable PFS on all the tunnels without bringing down the Pix520 firewalls? Since the pix firewall is running on an Intel CPU, I can always replace the current PIII 500 with another PIII 850 but I don't think cisco would like that. By the way, I am running Pix OS version 6.3(0) build 144. Even when I am running version 6.2(2), the performance is about the same. Anyone has the pix VPN setup with PFS without bringing down the pix, please advise. On another unrelated question: has anyone ever seen the pix firewall using more than 160MB of RAM? My pix firewall has 256MB of RAM but I have never seen it use more than 160MB. Even in lab environment where I hit the firewall with a lot of connections, about 1 millions simutaneous connection of http, https, ftp, telnet, etc... but the pix never uses more than 160MB of RAM. So does it mean on firewall such as Pix535 that can have up to 1GB of RAM, it actually never uses more than 256MB of RAM? Eric - Do you Yahoo!? Yahoo!

Me too. :-) It doesn't sound like he has any detailed information. Also, this sounds a little clueless: "The people who are writing the (Internet engineering) drafts are running out of financing because people aren't listening." What financing do they get??? I guess most of them are employed and their employers support their research, and the economic disaster that we're in right now could be a small factor. On the other hand, a lot of protocol designers are so dedicated to what they do, they would probaby do it for free. But I am impressed with the discussion we have had. It's been informative.

Let's put it this way -- BGP authentication has more options than just an MD5 signature on an update, which is really more authorization than authentication. The more comprehensive route authentication mechanisms call for a chain of digital signatures at every AS on the path, allowing authentication back to the originator. Even comprehensive authentication doesn't protect against incorrect origination. Protection there lies much more in validating routing policy, in using sanity checks like prefix limit and flap dampening, etc. >Also, >this sounds a little clueless: "The people who are writing the (Internet >engineering) drafts are running out of financing because people aren't >listening."

Funny you should mention that -- I just got off a teleconference doing what we hope is the final draft of the BGP Control Plane Convergence before RFC acceptance. Two of the four people on the call were laid off by the companies that directly supported their work (one is still going to the San Francisco IETF using her frequent flyer miles), while another's new employer really doesn't support the work. Attendance at an IETF meeting costs around $500, which covers the facility expense (with a fair bit of sponsorship), as well as contributions toward the upkeep of the secretariat. People or their employers pay their own way. If I were to single out one person as the top expert on BGP cryptosecurity, I'd mention Sandy Murphy, who does work for a security company. Obviously, they have a motivation for sponsoring her research. See http://www.cymru.com/Documents/barry2.pdf for some pretty recent work on noncryptographic (mostly) BGP security from Cisco. It updates the Cisco Press book on ISP Essentials.

Also, don't forget to manipulate the priorities so that the hub router becomes the DR. > Perhaps have I done a mistake or don't know ospf > enough.

NDA Violation or NOT [7:64179]
hi everyone ,i have a question about NDA that i am not sure about ,hope someone can answer me . I was offered a job a small training company to write a ccie lab guide but due to the NDA aggrement i signed in the ccie lab a few months back ,my question is if i write about Cat3550 ,routing protocol stuff (NOT same question,diagram ,score ,time ... like in the real lab ) will i BREAK any NDA then ,for instance the lab had 2 CAT3550 and every one knew about it ,but if i write about a question like create vlan xx and connecting 2 cats toghether , will it fall under NDA violation if i write "NEXT TASK IS TO USE CONSOLE PORT TO CONNECT the switch , allow only VLAN xx to pass,and create some thing to put port in :-) " or i can write TRUNKING on port xx ... and create vlan xx. and about protocol , ospf ,eigrp ,rip ,bgp Or is it freely to write any thing but the question must not look like the lab but still contains same routing,switching protocol like in the lab . Like Mr Karl Solie books ,he also a ccie and his books got lots of stuff very close to the real lab according to amanzon feedback, how come cisco didnt NDA him yet ,or ciscopress can publish those NDA stuff any time they want ?,is it a time limit for NDA after the lab ? many thanks Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=64179&t=64179 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

There is only so much that can be said. If you were to say "here is what I saw in the CCIE Lab when I was there" and provided information, that would be NDA. On the other hand, if you were to start by identifying core topics, core skill sets, and go from there, you are probably OK. Is Caslow a violation of NDA? NLI? IPXpert? Etc? Or maybe to put it another way, is it any real secret as to what the core topics are? >the lab had 2 CAT3550 and every one knew about it > ,but if i write about a question like create vlan xx and connecting 2 cats > together , will it fall under NDA violation if i write "NEXT TASK IS TO USE > CONSOLE PORT TO CONNECT the switch , allow only VLAN xx to pass,and create > some thing to put port in :-) " better way to put this might be to consider skill sets necessary to proclaim "expertise" and write around emphasizing those skill sets. So, for multiple switches in any environment, let alone the CCIE Lab, what are the expert level things one should know? for example, trunking? VTP? etherchannel? fallback bridging? vlan failover? various spanning tree functions? vlan tunnels? etc? >Like Mr Karl Solie books ,he also a ccie and his books got lots of stuff > very close to the real lab according to amanzon feedback, how come cisco > didnt NDA him yet ,or ciscopress can publish those NDA stuff any time they > want ?,is it a time limit for NDA after the lab ? I got a better one for you. Cisco publishes the ASET labs for Cisco employees and partners to use for CCIE preparation. Forget NDA. Is this fair? that working for a partner I can see practice materials written by Cisco that someone else who does not have that advantage cannot? that I can attend Cisco sponsored training that others may not? >Or is it freely to write any thing but the question must not look like the > lab but still contains same routing,switching protocol like in the lab . > I think you're OK if you stay clear of any implication that you are revealing what you saw in the Lab. When I wrote my white paper, available on Cert Zone, I had not yet seen the new Lab. Now that I've been through the new Lab, I make very sure that I do not make statements about whether or not the paper is close to what I saw in the lab. What I do say is that the topics covered are part of an expert skill set that I believe are required, especially now that I am doing a lot more big campus switching projects for customers. as such, the knowledge cannot hurt when one prepares for the Lab. note - the message below was cut in order for me to respond without my news client crashing.

Span Port on 5000 [7:64186]
Ok, I'm trying to capture TCP, specifically Telnet traffic going between two routers on 2 ports of the bridge. I have a protocol analyzer on port 1/2 (I've tried other bridge ports as well). The routers come in on 1/2 and 2/3. To start I enter the command 'set span 2/3 1/2 both' on the 5000 bridge. I do a 'show span' to check that the configuration took, all looks good. I fire up the analyzer on 1/2 and succesfully initiate telnet from one router to the other. My problem is that I see no TCP traffic at all, plenty of CDP, OSPF and STP traffic but no TCP. When I telnet from my box to the router I see plenty of the Telnet traffic. Why am I not able to see the traffic via the span command? Thanks.

Configuring CIR on a cisco 2522 FR switch [7:64187]
Hi group, I have a cisco 2522 router that is configured as a frame relay switch. I am trying to configure CIR on serial 4 so that if the router connected to s4 is sending more traffic than the configured CIR, packets will be dropped at fhe frame relay switch. I configured the CIR on the switch but it seems that the router connected to s4 can still send traffic at rates exceeding the CIR, and the FR switch will not drop any packet.

Re: routername(boot) ??? [7:64188]
You need to set the configuration register to 0x2102. This enables the router to boot from flash.

Re: Question concerning a new 2501 router in home lab [7:64170]
Thanks to all that responded. The problem is solved. I found an article that related to this type of problems in 2502 routers that had an older version of the boot rom not exerting CTS to allow the term emulator to send information to the console port. By disabling flow control the problem was resolved. Again thanks to all who responded.

Re: Configuring CIR on a cisco 2522 FR switch [7:64195]
I dont beleive it will work on routers that are frame switching in the lab..I thought I read that it will only work with the real frame relay switches... Larry Letterman Network Engineer Cisco Systems - Original Message - From: John Tafasi To: Cisco Group Study ; ccielab Sent: Saturday, March 01, 2003 6:47 PM Subject: Configuring CIR on a cisco 2522 FR switch Hi group, I have a cisco 2522 router that is configured as a frame relay switch. I am trying to configure CIR on serial 4 so that if the router connected to s4 is sending more traffic than the configured CIR, packets will be dropped at fhe frame relay switch. I configured the CIR on the switch but it seems that the router connected to s4 can still send traffic at rates exceeding the CIR, and the FR switch will not drop any packet.

Re: Span Port on 5000 [7:64186]
you have the analyzer and the router in the same port ? 1/2 according to the below text ? set span source-port dest-port in/out/both Larry Letterman Network Engineer Cisco Systems - Original Message - From: Richard Burdette To: [EMAIL PROTECTED] Sent: Saturday, March 01, 2003 6:48 PM Subject: Span Port on 5000 [7:64186] Ok, I'm trying to capture TCP, specifically Telnet traffic going between two routers on 2 ports of the bridge. I have a protocol analyzer on port 1/2 (I've tried other bridge ports as well). The routers come in on 1/2 and 2/3. To start I enter the command 'set span 2/3 1/2 both' on the 5000 bridge. I do a 'show span' to check that the configuration took, all looks good. I fire up the analyzer on 1/2 and succesfully initiate telnet from one router to the other. My problem is that I see no TCP traffic at all, plenty of CDP, OSPF and STP traffic but no TCP. When I telnet from my box to the router I see plenty of the Telnet traffic. Why am I not able to see the traffic via the span command? Thanks.
