Re: UDP port 1434 [7:61891]
Chuck, If I'm the Ken you're talking about and I actually said that, then I must really need a nap. :-) We're a university, where Microsoft rules. :-( I'd like to tell you how many MS-SQL servers we have, but I don't have a clue. There are probably some running in the dorms. We have entire labs where this stuff is installed so they can teach it. I'd like to tell you how many machines have the MSDE installed, but again I don't have a clue. Did I mention dorms? Changing the way the campus conducts "network" business is a difficult task. I'm doing a lot of educating - to the campus technicians. By this time next year, I hope to say we have 75% of the campus firewalled. While that may sound easy, it may be wishful thinking. Although... this worm might really make a difference in my timeline. :-) BTW, by now, one of my access-lists has probably broken the billion mark for blocking UDP 1434. That's only internal traffic. A question I have: Is anyone learning anything from my rambling? If not, I'll happily take questions and suggestions ranging from "how did you do X" to "why don't you take that nap".

Traceroute troubles [7:61247]---------- Thank You. [7:62023]
I am sorry i am late in getting back to you.. You have answered my question precisely You just cleared all the doubts i had... I donot think we can get any better explanation than this.Thank you very much. -Original Message- From: Priscilla Oppenheimer [mailto:[EMAIL PROTECTED]] Sent: Monday, January 20, 2003 2:53 PM To: [EMAIL PROTECTED] Subject: RE: Traceroute troubles [7:61247] Your question isn't clear. Maybe you could start over in a new thread and explain your question clearly, if the following info doesn't help. Once a thread gets this old, a lot of people ignore it. ;-) However, I think I understand your confusion. You are worried because Cisco and UNIX use a UDP message for trace route. So how could disabling the rate limiting of ICMP fix the problem where trace route seems to fail every so often? Yes, they send a UDP packet, but they depend on routers returning an ICMP Time-To-Live Exceeded message (ICMP type 11, code 0). If ICMP rate limiting is enabled on those routers, they won't send the message very time, making it appear as if trace route fails sometimes. Here's how it works, from my book Troubleshooting Campus Networks, that everyone should get, especially if you are studying for the Support test for CCNP. It covers all topics for that test. Hey, my publisher won't do any marketing for me. I'll have to do it myself. Hope that's OK, if I keep it to a minimum. :-) Anyway, here's the info. (There are more details in the book.) "Trace-route displays the sequence of hops a packet traverses to get from a source to a destination. The results provided by trace-route are a measurement of the round-trip time to each router in the path to a destination and also a measurement of the round-trip time to the actual destination. The timing measurements account for processing time at the recipients in addition to propagation delay. Trace-route can be used as a rough estimate of delays on a network. It is most useful, however, as a method for determining the path to a remote destination. With UNIX and Cisco IOS operating systems, an IP trace-route packet is a User Datagram Protocol (UDP) probe sent to a high UDP port number, usually in the 33,000 to 43,000 range. Trace-route works by taking advantage of the ICMP error message a router generates when a packet exceeds its time-to-live (TTL) value. TTL is a field in the IP header of an IP packet. Trace-route starts by sending a UDP probe packet with a TTL of 1. This causes the first router in the path to discard the probe and send back a TTL exceeded message. One of the first things a router does when forwarding IP packets is decrement the TTL (which is essentially a hop count value). If the decrement causes the TTL to reach 0, then the packet is dead (discarded) and a TTL exceeded message is sent. The trace-route command sends several probes, increasing the TTL by 1 after sending three packets at each TTL value. For example, trace-route sends three packets with TTL equal to 1, then three packets with TTL equal to 2, then three packets with TTL equal to 3, and so on, until the destination host is reached or a configured maximum number of tries (usually 30) is reached. Each router in the path decrements the TTL. The router that decrements the TTL to 0 sends back the TTL exceeded message. The final destination host sends back a port unreachable ICMP message, because the high UDP port number is not a well-known port number. This process allows a user to see a message from every router in the path to the destination, and a message from the destination. The trace-route facility in Microsoft operating systems sends a ping (ICMP echo) rather than a UDP packet. The trace-route command makes use of the IP TTL feature and router behavior with respect to TTL, but the packet is an ICMP echo instead of a UDP probe. The only real difference is that when the message reaches the final destination, the destination normally responds to the ping, rather than sending a port unreachable message."

RE: Too much Security Overkill on wireless network??? [7:62010]
I'm testing this very scenario at the moment. Just force the use of EAP and turn off Open and Shared authentication. I would probably pick (LEAP/PEAP + (BKR or TKIP)) or IPSEC. Although the IPSEC-only route wouldn't afford you the ability to deny surfing from the DMZ. EAP locks down the network access except for authenticated users. IPSEC might be overkill on top of PEAP. You could use PEAP to protect unicast transmissions and Broadcast Key Rotation to protect multicast/broadcast traffic. The broadcast key is securely transmitted to the client during the EAP authentication process. I will be forced to use LEAP instead of PEAP at the moment because of some CE devices, but the process is exactly the same except PEAP is slightly more secure. Can someone, Mas, please let me know if I need to enter in a WEP transmission key when using EAP and Broadcast Key Rotation? I know I need to turn WEP on, but I think I can just leave out the key and specify the length. Is this right? The documentation isn't very clear. -Original Message- From: 910T [mailto:[EMAIL PROTECTED]] Sent: Monday, January 27, 2003 11:53 PM To: [EMAIL PROTECTED] Subject: Re: Too much Security Overkill on wireless network??? [7:62010] Eric, Sorry to pile it on, but the error correction in an 802.11 wireless radio transmission also takes up almost half the throughput right off the bat (11 Mbit/s becomes about 6.5 Mbit/s net, best case). Perhaps SSH, SSL and EAP/WEP are superflurous when used with IPSec, but I would imagine that you need SSH and SSL to support users coming in from the "outside," or perhaps as an additional level of protection for individual users of sensitive applications from those with general network access ("most attacks come from within..."). Typically, WEP is done in hardware, so theoretically, there shouldn't be any overhead if that is the case. But if you want to eliminate it, why not use force the use of EAP for wireless admission control but leave WEP off?

Hi, I have assigned the task of setting up a wireless network for my company and I am wondering that I use too much "security" for the wireless. Currently, I am setting a test wireless network for about 5 users. Eventually, this network will have about 50 users. My set up is as follows: 1) The wireless network is sitting on the DMZ network. This DMZ network is hang off an interface of a pix firewall (Pix-525). Wireless users are required to use Protected Extensible Authentication Protocol (PEAP) in order to log onto the wireless DMZ network. 2) In order to access the company iternal network which hang off the "inside" interface of the pix firewall, wireless users must use Cisco VPN Client IPSec to establish a secure VPN tunnel between their device and the Pix firewall. 3) After succesfully establish the VPN tunnel between the wireless device and the Pix firewall, wireless can only access the company internal network applications via SSL, SSH, POP3s and IMAPs. I have a few users that tunnel X-application via SSH connections. Applications such as POP3, telnet and IMAP are not allowed from the DMZ network into the company internal network. So far the test is going well. However, my concern is that this will not scale well for a large number of wireless users. For example, let say for SSH connection, the traffic is "encrypted" by SSH. Below that, it is "encrypted" via IPSec. Finally, it is "encrypted" by PEAP. I've not done any analysis yet but it is possible that 50% of the traffic is just "overhead" traffic for encryption. Anyone has successfully implemented a "secure" wireless network on large scale? I would like to get your advise on this. I have to present a recommendation to my CTO in a next few days. By the way, my company did hire a CCIE security consultant to work with me on this project; however, this CCIE security is a "f_cking" moron. Not only he doesn't know anything about PEAP, but he even suggested that we use Cisco LEAP because LEAP is much more secure than PEAP. After he couldn't get PEAP to work, the SOB suggested that we switch to Cisco LEAP. When we don't want to use Cisco LEAP, he suggested that we just use "shared (aka STATIC WEP)" authentication because we are using IPSec and Secure applications to access the company internal network anyway. The problem with this idea is that once wireless users are on the dmz wireless network, they can surf the Internet without restrictions. I don't want strangers (if they get a hold of the STATIC WEP KEY) to use my company bandwith to use the Internet. I want PEAP because it is safe and secure. I am also testing EAP-TTLS but haven't had much luck

RE: Richard A. Deal Books [7:62027]
I think his PIX book is very good. I've not found many errors in it but then maybe I've not looked at it in as much depth as you have. If I have a gripe about it it's for one thing. I use it as a desktop reference. Sometimes I'm looking up how to accomplish "X" and find out that before I can do that I need to accomplish A, B and/or C. The instructions will simply say "That process was covered earlier and won't be repeated here. Now to accomplish "X"." Earlier? WhereEXACTLY? I've spent more time looking for "earlier" sometimes than I do accomplishing the task at hand. "Earlier in this chapter under the blah heading" or "this was covered in the chapter on blah blah" would be helpful. As far as the info in the book goes I've found stuff in there that I can't find at CCO (it may be there but I can't find it) or anywhere other than maybe from tech in a TAC call. Either that or I've had to look for it in a dozen different places and now it's all together in one book. It's the best book I've found on using a PIX. Beats the Cisco Press book on the PIX by a long shot. Don't know about any others he's written. IMHO.

RE: ACL memory space [7:62028]
Hmm you must have some freakin' long ACLs! :-) Still, that's pretty strange behavior. I don't know if the feature is available on that platform but you might try using "access-list compiled" to allow the router to process them more efficiently. I doubt that would even help this problem, though. If you're truly running out of config space try using "service compress-config" to free up some room. It sounds like you may be running into a 'feature' that TAC might be able to help with. John >>> "[EMAIL PROTECTED]" 1/28/03 9:37:22 AM >>> The router is a 3640.

This problem is thoroughly baking my noodle so I thought I'd post it here. It involves some hardware and software I wouldn't normally be involved in, but they've come to me for help. We have Novell Migration Agent running on a bunch of servers in our network. The MA is in constant communication with several other servers. Just this morning, the destination IP addresses of MA-generated packets are being reversed. For example, a server is trying to reach 10.20.30.40, the destination is being rewritten as 40.30.20.10 before it goes out onto the wire. Have any of you seen anything like this? No one here has, and we're not really sure how to proceed. It appears to be a problem with Novell Migration Agent, but it's an awfully strange problem. Any ideas?

I believe if you turn just EAP on, you'll get a dynamic WEP key for unicasts but you'll need to specify the static WEP key to be used for broad/multicasts. If you turn EAP with broadcast key rotation on, you don't need to specify a static WEP key for broad/multicasts because the AP will create and rotate them dynamically at the specified interval.

[7:62010] I'm testing this very scenario at the moment. Just force the use of EAP and turn off Open and Shared authentication. I would probably pick (LEAP/PEAP + (BKR or TKIP)) or IPSEC. Although the IPSEC-only route wouldn't afford you the ability to deny surfing from the DMZ. EAP locks down the network access except for authenticated users. IPSEC might be overkill on top of PEAP. You could use PEAP to protect unicast transmissions and Broadcast Key Rotation to protect multicast/broadcast traffic. The broadcast key is securely transmitted to the client during the EAP authentication process. I will be forced to use LEAP instead of PEAP at the moment because of some CE devices, but the process is exactly the same except PEAP is slightly more secure. Can someone, Mas, please let me know if I need to enter in a WEP transmission key when using EAP and Broadcast Key Rotation? I know I need to turn WEP on, but I think I can just leave out the key and specify the length. Is this right?

Perhaps SSH, SSL and EAP/WEP are superflurous when used with IPSec, but I would imagine that you need SSH and SSL to support users coming in from the "outside," or perhaps as an additional level of protection for individual users of sensitive applications from those with general network access ("most attacks come from within..."). Typically, WEP is done in hardware, so theoretically, there shouldn't be any overhead if that is the case. But if you want to eliminate it, why not use force the use of EAP for wireless admission control but leave WEP off?

Hi, I have assigned the task of setting up a wireless network for my company and I am wondering that I use too much "security" for the wireless. Currently, I am setting a test wireless network for about 5 users. Eventually, this network will have about 50 users. My set up is as follows: 1) The wireless network is sitting on the DMZ network. This DMZ network is hang off an interface of a pix firewall (Pix-525). Wireless users are required to use Protected Extensible Authentication Protocol (PEAP) in order to log onto the wireless DMZ network. 2) In order to access the company iternal network which hang off the "inside" interface of the pix firewall, wireless users must use Cisco VPN Client IPSec to establish a secure VPN tunnel between their device and the Pix firewall. 3) After succesfully establish the VPN tunnel between the wireless device and the Pix firewall, wireless can only access the company internal network applications via SSL, SSH, POP3s and IMAPs. I have a few users that tunnel X-application via SSH connections. Applications such as POP3, telnet and IMAP are not allowed from the DMZ network into the company internal network. So far the test is going well. However, my concern is that this will not scale well for a large number of wireless users. For example, let say for SSH connection, the traffic is "encrypted" by SSH. Below that, it is "encrypted" via IPSec. Finally, it is "encrypted" by PEAP. I've not done any analysis yet but it is possible that 50% of the traffic is just "overhead" traffic for encryption. Anyone has successfully implemented a "secure" wireless network on large scale? I would like to get your advise on this. I have to present a recommendation to my CTO in a next few days. By the way, my company did hire a CCIE security consultant to work with me on this project; however, this CCIE security is a "f_cking" moron. Not only he doesn't know anything about PEAP, but he even suggested that we use Cisco LEAP because LEAP is much more secure than PEAP.

trunking 10/100 access ports for avaya ip phone [7:62045]
Anyone have any insight on the pro's or con's regarding applying trunks to all 10/100 access ports on a 6509. Presently, I have a cisco voIP environment - using a data vlan and an auxiliary vlan for voice traffic. I've been asked to make an avaya phone work in this environment. Input from Avaya had me make the access port a trunk, make the data vlan the default vlan and apply the aux vlan to the port as well. It does work - my question is in regards to performance and/or design best practices. TIA Robert LEGAL NOTICE Unless expressly stated otherwise, this message is confidential and may be privileged.

PIX Scenario [7:62047]
Hello everyone, I would like to install a PIX behind a router and had some questions... 1. Can the VPN clients connect to a public ip that translates ( static nat ) to the private ip assigned to the outside interface of the PIX?( if i use esp) 2. Will it work if I use IKE Mode Configuration to auto assign IPs to the remote clientsor does the "vpngroup" configuration with PIX v6.01 work the same way? Thanks for any suggestions...If i am being to vague I would be happy to discuss in more detail.

RE: Cisco 831 routers [7:61707]
Glad to help Thomas. My experience with lower-end 2600's (2611/2621) is that they can reach approximately 500-750Kbps of 3DES IPsec performance (depending upon traffic type; purely 1440-byte packets might get you north of 800Kbps). The 831 is rated, as per Cisco (http://tools.cisco.com/cmn/jsp/index.jsp?id=20753), at around 2Mbps with standard traffic, so real world performance should be better (64-byte packets induce the greatest amount of stress). This, plus the punting of LLQ into the crypto engine, Websense/N2H2 content filtering and virtual AUX makes this little router quite acceptable for small offices, though there isn't any modularity of course (e.g. no WICs, no NMs).

Re: Inquiring Minds want to know [7:61985]
Normally you would want to fix the ports on connections you know will not change, like trunks, routers, servers, etc. You do have to watch out for vendor implementations however. When troubleshooting issues with an IBM 2216 router (think 7507 with CIP) I found a tech note from IBM stating that switch ports had to be in auto for the 2216 Fast Ethernet card ports to come up reliably.

I'm finding that more and more often this is the case, especially with newer switches. According to spec, auto is the only way to go. Any other configuration is not mentioned in the spec and the behavior is vendor-dependent. That translates to more support calls, unfortunately.

The HSSI interface is mechanically identical to the SCSI2 connector, which is a couple of inches wide. The newer Smart Serial is a very compact little dude that you find on the WIC series of interfaces. I though Smart Serial was Cisco-proprietary, but I understand a few others are using it as well. I've never been able to find any kind of spec on it. As far as I know, the Smart Serial has only been used by Cisco for lower-speed interfaces (up to E1) whereas the HSSI goes up to around 50 Mbps.

RE: NAT and VoIP [7:62053]
You may indeed experience issues with NAT and VoIP. You will have to revisit your NAT pool and review the address schema for your IP telephony end points and most likely adjust your pools accordingly. This will also, depending on the size of the deployment and enterprise, probably cause you to have to review your DHCP scope(s) as well. Will Gragido CISSP CCNP CIPTSS CCDA MCP 9450 W.

cat6500 ethernet module question [7:62063]
Hello listers, does anyone know the technical difference between the ws-x6148-rj-45 and ws-x6348-rj-45 modules for the cat6500 switches? the price difference is very significant though the documentation on Cisco's web site doesn't show any technical difference.

Re: Richard A. Deal Books [7:62027]
Mark, Thanks for the kudos. I worked really hard on the book and I know, after having written 6 books, that you can't please everyone. However, of all of the books that I've written, I'm proudest of this book. Yes, there are some errors that slipped in during my last review of the book and when it went to production, which does, unfortunately, happen. But as I discover these, I put them on my web site. As to my MCNS book, which is what the first poster asked, I had finished it, but before it went to print, the publisher (The Coriolis Group) went out of business. Since the MCNS has changed, I've decided not to create a new book. I'm getting a contract this week to write a CCNA book for McGraw-Hill and have been desparately trying to convince them to write a Cisco VPN book--one that covers ALL aspects of VPNS with Cisco products--PIX, router, concentrator, and their software clients.

I believe that Cisco also charges support on some fabric-enabled LC's, in particular - 16-port Gigabit Ethernet modules. You may see Cisco (as with other vendors) charge per LC on high-end platforms like the Cat6k, especially when feature-rich vs. feature-free modules are concerned.

The 6148 should also only be used in the access layer, but should be purchased in favor of the 6348 today (the 6348 is outdated). the 6148-rj-45v module can be used for voice applications. The 6548 module is a 10/100 Ethernet module more suited for the network core, although I'm not sure what applications would be needed in the "core" (maybe at the edge for peering?) for 10/100 Ethernet. Possibly for packet capture devices run to SPAN/RSPAN -enabled ports? Other NMS devices??

Re: PIX Scenario [7:62047]
Hi If you want VPN client to connect to your pix, you need to assign a public IP to your outside interface and you can create a pool of private ip address to your vpn client by using (ip local pool start ip...end ip) and give the pool name in the vpngroup configuration (vpngroup address-pool . There are lot of document given in cisco's website. fahim ""Dain Deutschman"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hello everyone, > > I would like to install a PIX behind a router and had some questions... > > 1.

RE: HSRP PROBLEM [7:62057]
the routers send hellp packets using a multicast address - check that this is not being blocked somewhere. -Original Message- From: .
