Hi Dear Friends,
I have 1 branch office connected to main office by frame relay. I
noticed a lot of traffic across this link and would like to find out
what they are. The problem is I don't have access to the branch office,
therefore, everything has to be done in main office. I tried sniffer
pro, etherpeek and anasil but they only allow me to specify a particular
source IP, not the whole branch office subnet. Is there any other
software I can use?
Thanks.
Yoshi

Re: What is the best HyperTerminal program for Linux? [7:41228]
do you mean configure? or compile it on a machine?
minicom was created to mimic the old telix software from back in the day!
:) configuing is easyjust run minicom and hit alt-z for the help menu...
you'll need to select 'o' for configurationremember to take out the init
strings and hangup strings...you don't want garbage being sent to your

Does anyone know of a good step by step tutorial for setting up minicom
for use to terminal into routers and switches? Pardon my ignorance,
I've done a good amount of work with linux, but I've never used any
terminal program besides HyperTerminal (don't laugh) on anything but
windows. I've been studying over the man pages, but they're about as
confusing as I've found.

Dialer profile vs. rotary group? [7:41271]
Hey all, I am confused by the difference(s) between dialer profiles and rotary groups. All the text I've read seems rather convoluted - physical interfaces can only be in one rotary group but can exist in many different dialer pools (if using dialer profiles)? Is that the main difference? Rotary groups seem to be an outdated configuration solution. Someone please point me in the right direction...

Re: Now What???????? [7:40988]
Careful now. I have been on the other side of the hiring process, and I know quite a few hiring directors who will instantly throw away any resume that says anything like "CCIE-written". The rationale is that they are trying to claim a cert that doesn't exist, and so if they're willing to push the envelope on that, then most likely everything else on their resume is greatly exaggerated, if not an out-and-out fabrication. From what I see, you lose more than you gain by listing such a cert. ""x"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Juan, > Send me your resume and I will help you with it.

Check the clock rate and cabling on both ends. If the clock rate specified is different than what the module supports, then I believe the line will come up and go back down.

RE: How can you block spam email with NBAR? [7:41029]
AFAIK, you can only block HTTP content using NBAR, although Cisco is working on adding additional protocols for classifying content. You can use the IDS features in the IOS to catch some SPAM related mail, such as the number of recipients in an email message. Based on this you could setup your mail gateway to reject mail from certain domains in the future. Your best bet is to install a real SMTP gateway filter that will allow you to block SPAM and emails with certain attachments. (i.e. .exe, .vbs, .bat, etc) You can find some open source tools for these sorts of tasks here: http://www.linux.org/apps/all/Administration/Anti-Spam.html and here: http://www.amavis.org/ HTH, Kent -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of BH Sent: Wednesday, April 10, 2002 6:29 AM To: [EMAIL PROTECTED] Subject: How can you block spam email with NBAR?

RE: CCIE Written Reading.. [7:41017]
as far as Boson test go, use the one that works for you.. I used the one by Bernard and it didn't work for me, I used the one by Dennis and I think it prepares one for the written test a great deal better...everyone has thier own method of studying and choosing tools As far as implying that I spend my day posting to this board all day and getting paid for it, that would be incorrect...But yes my company does allow me to use the web and email to learn and converse with others in my trade, which allows me to be a better, more knowledgeable network person...and on occasion when I think I can help someone elseon here I offer to give something back to the list since the list gives me a lot of information that helped me thru the written as well as day to day activity... Lastly, I am not doing the CCIE for the money, I am doing it because I want the cert and I will learn alot about the networking business by making myself do the labs and prove to myself that I can do it and that I know what I think I know.. Larry Letterman Cisco Systems [EMAIL PROTECTED] Larry, Well, it did work for me and as you see I am going for the lab now. Of course, ccbootcamp, Boson, cerificationzone these are all just tools. The actual result varies depending on the person's capacity. But, I am curious. Why do you want to become a CCIE? I want to become a CCIE with the hope and anticipation of a better job, a better income, and a better life. You already have a better life. Your signature says you work for Cisco, and you are constantly on this list. This means you are getting paid for surfing and chatting! This is an ultimate job. I love it.

4006 Power Supplies [7:41257]
Im trying to understand power redundancy in the Cisco 4006 switch. Reading through the online information, Cisco seems to imply you must have at least two power supplies up and running at all times. The 3rd power supply provides redundancy. Other vendors allow you to run at least a partially populated chassis on one power supply. If I have a 4006 with SUPII and one 48-port blade, do I really need three power supplies? Anyone have experience with 4006s and power supplies? Thanks!! Jeffrey Reed Classic Networking, Inc.

Do you have another router to connect to the 3660? This would give you a better idea of how it really works.

Re: How fast do bits travel ? [7:41192]
Not totally true. I will have to look up the formula but there is one for computing delay on a line and it does come into play. I have a large voice network to latin america. You are right the each router adds a chunk - about 20 ms of delay if they are not overloaded, but a line down to Argentina adds almost as much and that is if it is fiber all the way. When you start looking at voice budgets you have to take line delay into account. >From: "sam sneed" >Reply-To: "sam sneed" >To: [EMAIL PROTECTED] >Subject: Re: How fast do bits travel ?

Re: Ping times? Am i missing something [7:41151]
Okay, I'm much clearer on this now. So in reality, the IP TTL
doesn't really measure anything anymore, we just need to make sure our
routers decrement it so that a box getting an IP packet with 0 will
discard it any not let it float around the networka aimlessly.
Thanks for the help. Much appreciated!

As usual, you guys have come through with much, much help. I can't thank you enough. Regrettably, the only terminal emulation program I've used to date is HyperTerminal. Thanks very much.

Try www.nerdbooks.com. Theri prices are just as good if not better. If you have a question, you can call and the owner or one of his in store staffers will take the call personally.

Passed CSIDS - now a CSS1 [7:41227]
Just finished the CSIDS exam, completing the series of four to become a CSS1. My take, if anyone is interested, is below, and tests are in the order I took them: MCNS - I'm glad I took this one first, as it covered all the material of the next two exams. CSPFA - A slightly more focused rehash of MCNS. I referred back to MCNS quite a bit to clarify info. CSVPN - Again, most everything was covered in CSPFA and MCNS CSIDS - All in all, the easiest of the exams. In all cases, the only prep material I had was the courseware and Boson exams. I've worked with the Pix for 3 years, but unfortunately have no hands-on exposure to the CSDIS hardware. Almost all the tests were difficult, none terribly so, and the CSIDS exam was just this side of a joke. The tests were also better written than the CCNP/CCNA exams I've taken. If I wasn't so tired, this would be louder: woo hoo.

Miles per seconds! ;-) As Wes said, "The rough calculation for the propagation of an electromagnetic signal in wire is 66% of the speed of light in a vacuum. Or 186000 x 2/3 = 124000 miles/sec." Here's what we'll be saying in our new book. (It is copyrighted, so don't steal the exact wording please, although the concepts are certainly universal! ;-) "A signal in a cable propagates at roughly 2/3 the speed of light in a vacuum. The value 0.59c is used for twisted-pair cabling, where c stands for the speed of light in a vacuum, which is 300,000 km/s, or 186,282 mi/s. To determine how far a signal can travel in 1 second, use the following equation: 300,000 km/sec * 0.59 = 177,000 km/sec In 1 second, a signal can propagate 177,000 km. In that same second, there can be 10 million bits on a 10-Mbps Ethernet network. Hence, the electrical energy associated with a single bit stretches out 0.0177 km or 17.7 meters. A single bit is a very long thing on a cable. The mental image that many of us have of bits looking like numerous little box cars in a railroad train, moving along a cable, is not very accurate. The 100-meter cable between a workstation and a wiring closet, for example, contains only about five discrete bits." (By the way, this has some real-world relevance in Ethernet CSMA/CD. You know how you always hear that a single collision domain must not exceed the round-trip propagation delay of a minimum sized-frame, 512 bits? The info above can help you figure out if your network exceeds that or not.)

RE: How fast do bits travel ? [7:41192]
There are several factors: 1) Clock rate of the line 2) Buffering delay by any intermediary devices such as ATM/FR switches 3) Speed of light If we take a simple case and say that there are no layer 2 devices in the path and only digital cross-connects. I have read (somewhere) that the speed of electron transference in copper is a little faster than the speed of light in fiber over short distance, so use the speed of light in fiber (roughly .7 X 186,000 miles per second) as the baseline. (note that the reference given by another poster says the speed of electromagnetic signals in copper is .66 of the speed of light, which would mean it is slightly slower than speed of light in fiber, either way its pretty close to a wash) Given these assumptions you get: speed of a single bit = speed of line insertion for 1 bit + speed of light delay + speed of line removal for 1 bit speed of line insertion for 1 bit = speed of line removal for 1 bit = 1/clock rate speed of light delay = number of miles / (.7 * 186000 miles per second) As an example, for a clock rate of 128Kbps and a distance of 1000 miles: speed of line insertion and removal for 1 bit = 2 * (1/128000) = .15625 sec = .015625 ms speed of light delay = 1000 / (.7 * 186000) = .00768 sec = 7.68 ms 7.68 ms + .015625 ms = 7.7 ms (roughly) Again, this assumes no delay in buffering in the path of any kind. It also assumes that there is no congestion at either end of the link. Bottom line, keep in mind these are rough numbers, but I think you get the idea.

Re: Ping times? Am i missing something [7:41151]
Timoue (timeout!? ;-)
IP TTL is a reverse hop count. The sender sets it to some large number like
255 or 64 or 32 (depending on the OS). Each router decrements it by one. If
that causes the TTL to become zero, then the packet is dead. The router
discards it. The goal is to stop a packet from travelling around an
internetwork forever, which could happen if there were a routing loop.
Originally, the IP designers also envisioned that the TTL could be a rough
measurement of time. A router could decrement the TTL by more than one if
it took more than one second to handle the frame. The router could
decrement the TTL by the number of seconds it took to work on the frame.
These days if a router took more than a second to forward a frame, you
would pull the plug and use it as a boat anchor.
Some protocol analyzers still show the TTL value as hops/seconds. I think
the Sniffer still does this. It's misleading for two reasons. No routers
use seconds anymore, and the hops/seconds makes it look like a ratio. Ugh.
One more comment, you were worried about 15,000 milliseconds. Remember
that's only 15 seconds. So if the TTL were measured in seconds, 255 would
be much bigger.
By the way, my ping using 3600 seconds on my Albany router (see my previous
reply) is still sitting there!

IPX Internal Address - IPXWAN [7:41207]
Hi, Can someone point to a URL that points out the reason why a NetWare server's Internal IPX address must be unique throughout a NetWare domain in spite of the fact that it is used only internally, i.e. "locally significant"? Since this requirement apparently implies that this address is checked for uniqueness, what packet would carry this between IPX devices (including routers configured for IPXWAN), SAP / RIP / NCP ? Thanks.

Re: How fast do bits travel ? [7:41192]
The speed the bits travel should be negligible in comparison with the time it takes the intermediate(routers, switch,...) and end nodes to receive/process the signal. So if you're curious for computational purposes it wouldn;t matter. Electricty in a vacuum travels at light speed. I'm not sure the effect a copper medium would have. It would probably be less due to interference and other electromagnetic influeneces. sam sneed ""Matthew Tayler"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Ok I have spent ages trying to find an answer to this question, and probably > only added to my confusion.

RE: OT Again: SNMP and TimeWarner Cable [7:41196]
Well, yes and no. Initially I was behind a Linksys firewall that's doing PAT. Supposedly, there's a transparency setting in the Linksys that'll allow SNMP traffic through to the designated end device. Since I made the correct settings in the Linksys and I was still having the problem, I removed the Linksys completely and went with a public IP on a single machine. This didn't solve the problem either. I suppose that there's the possibility that I'm being natted somewhere along the carrier path, but if so, I assume it would show on the trace as either a private address or a *. All I see are publics. Thanks, Craig At 01:04 PM 4/11/2002 -0400, you wrote: >As far as I know, SNMP does not work over NAT or PAT.

In theory, doesn't electricity travel at the speed of light? 186,000 feet per second, I think. I once read theory that electricity flows through copper more efficiently than light flows through fiber, so the electrical bits would arrive first in a race.

The rough calculation for the propagation of an electromagnetic signal in wire is 66% of the speed of light in a vacuum. Or 186000 x 2/3 = 124000 miles/sec.

RE: configure VPN on PIX which behind PAT router [7:41090]
You could, if the PIX supported NAT transparency for IPSec like the VPN 3000 does. Unfortunately, this feature is not yet available. My SE tells me its on the road map for inclusion sometime this year, but there are no firm dates yet. Your other option would be to get rid of the cayman router, but you probably would need PPPoE support on the PIX for your DSL connection, which according to the 6.1.3 release notes is also not an option yet. (if you don't need PPPoE, I'd get rid of the Cayman right now) Otherwise, you'll have to wait for PPPoE support in the PIX, which should be in the next major release. The only option I see for you without using different hardware is to use PPTP as an interim solution. You'll need to allow certain ports and protocols through the Cayman. Here's a link that shows what you need, it's for the PIX but you can adapt it for the Cayman: http://www.cisco.com/warp/public/110/pix_pptp.html Then you'll need to configure the PIX to support PPTP: http://www.cisco.com/warp/public/110/pptppix.html Keep in mind that PPTP is not as secure as IPSec. Some of the problems with PPTP were addressed by MS with MSCHAP-2, but there are still issues. I would only use this as a short term solution.

You are 100% correct when you describe my limitations. Well, I am doing something " Mission Impossible". I have setup the PIX firewall without NAT. It's the Cayman Router who did the PAT. And I did Pinhole on Cayman router to the mail server which behind the firewall. Everything works fine, except the VPN, I want to have some ideas first before I try to configure it. I know that on Cisco VPN Client, we can configure the IPsec over UDP or TCP. I wonder if there is additional configuration on the PIX firewall as well to support the UDP or TCP port 1.

Yep, you guys are correct. "^" is the beginning-of-line character, and "$" is the End-of-Line character. This means that ^10$ indicates the exact string of "BOL,AS10,EOL" or an as-path that includes only AS10. In order for this regex to be of any use to you, AS10 must be a neighboring AS, otherwise this would be an impossible condition for a BGP router in your AS to match.

Re: Change the Bridge ID on a cat5k [7:41188]
Tisk tisk!! Hehehee, you cheated Tim. hahahaha. See, I have eyes in here too. Well, the quick answer is NOT POSSIBLE. The long answer is this: Cisco's Catalyst OS makes a pool of 1024 addresses available to the switch. The switch will assign addresses to each VLAN, PORT, etc. sequentially until it is exhausted. THe SC0 gets the last address in the first module's range. This is ALL BURNED IN AND NOT CHANGEABLE EASILY. Or so I have been told ... Hard answer is that it is doable in ENGINEERING MODE or something. So I am still digging for this.

RE: About IOS question [7:41031]
Dumb question but, You are talking about a router IOS? Or maybe you want to know if PPPoE works on Pix? I know pix supports it in like 6.2. For Routers, of course you have to have the correct interface, and I believe they sell special IOS versions just for ADSL. Any idea on what model router? If it's a 12,000 I don't think they have it ;) Also if you looking to make a firewall with PPPoE, don't plan on using a dynamic IP. I have found in my experience using DHCP on an interface with a firewall is like mixing fire and ice. If you have DCHP use a normal router with "client side" DCHP, and then use the other interface to bind your packet filters to. -Original Message- From: Ricky Chan [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 10, 2002 9:46 AM To: [EMAIL PROTECTED] Subject: About IOS question [7:41031] Hi, Does anyone know which IOS version can support PPPoE + NAT + Firewall function.

I'm trying to change the Bridge-ID (BID) for a particular vlan on a cat5k. I know it's possible if I just change the priorty for that particular vlan. Is it possible to change the mac address on a vlan so that the BID will change without change the prioty. Here's the question that was posed "how does one change the bridge ID for VLAN 200 on a Catalyst 5000 (os is 5.5(10)b" Can anyone help?

RE: packet size [7:41079]
Your right Priscilla :) Yea, your also right about the different layers, because at layer 3, you could have 0. I found that "802.5 has no min packet size" "IEEE 802.3 networks have a minimum packet size that depends on the transmission rate. For type 10BASE5 802.3 networks the minimum packet size is 64 octets" "IEEE 802.4 networks have no minimum packet size. IEEE 802.4 networks have a maximum packet size of 8191 octets including all octets between the frame control and the FCS inclusive" http://www.freesoft.org/CIE/RFC/1042/10.htm -Original Message- From: Priscilla Oppenheimer [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 10, 2002 8:17 PM To: [EMAIL PROTECTED] Subject: RE: packet size [7:41079] At 06:00 PM 4/10/02, Brian Zeitz wrote: >Well, maybe the reason why its 64 bytes, is because of CSMA/CD >parameters call for 64 bytes. Would this make sense? No, it doesn't really make sense if you think in layers. ;-) And in fact, I'm sure I've seen a smaller IP packet than 64 bytes on Token Ring. What makes you think the minimum IP packet is 64 bytes? I haven't seen this in RFCs, but maybe you found such a thing. > Now what about CRC? >Is that extra bits, or is CRC part of CSMA/CD. The CRC is extra bits. It is not related to CSMA/CD, although a frame damaged by a collision will have a CRC error. >I am asking a lot of >questions today :O > >Looking at some of this, I am surpised how little Doyles Vol 1 and 2 >TCP/IP mention this stuff. It's layering. TCP/IP doesn't care about CSMA/CD. CSMA/CD is handled by the data-link layer. >Maybe its more for the CCIE outline.

SSH connexions [7:41178]
Hello group, The default SSH port is 22. For security reasons we would like to modify this port to another value for VTY connexions. How can I modify the default SSH port for VTY connexions on a Cisco router. Thank you for any information.
