what is Bearer capability not implemented in ISDN ? [7:13182]
Hello all, When I am trying to generate the call on ISDN ,I am not able to connect the ISDN Upon debug ISDN events and debug isdn q931 ,I got the cause to be as follow Cause i = 0x82C1 - Bearer capability not implemented The sample of the debug is given below for more help.Can anybody tell me this could be due to what ? Is it a line problem because I tested the line voltage and found to be around 105.6 Volts ,Also Upon connecting the ISDN instrument to this line I am able to get dial tone as well as generate voice calls? 4w1d: ISDN BR1/1: Outgoing call id = 0x8F65 4w1d: ISDN BR1/1: Event: Call to 6156540 at 64 Kb/s 4w1d: ISDN BR1/1: TX -> SETUP pd = 8 callref = 0x0B 4w1d: Bearer Capability i = 0x8890 4w1d: Channel ID i = 0x83 4w1d: Called Party Number i = 0x80, '6156540' 4w1d: ISDN BR1/1: RX <- RELEASE_COMP pd = 8 callref = 0x8B 4w1d: Cause i = 0x82C1 - Bearer capability not implemented 4w1d: ISDN BR1/1: received HOST_DISCONNECT_ACK call_id 0x8F65 4w1d: ISDN BR1/1: Error: Unexpected Disconnect_Ack - call id 0x8F65.

Were the instructions for verifying and restarting your tacacs process
available in your disaster recovery documentation? Do your CCIEs know where
the disaster recovery documentation is, and how it's organized?

Re: what's wrong with CCIE today? [7:13151]
Well, This Cisco guy knows how to configure, trouble shoot, install, and just about anything on an NT or 2000 box... As well as a Novell Box v3-1x -4.x. As far as Unix, well, not much expertise there... I can install various versions of Linux, but my demands of other areas have been far too great to specialize in everything... If it were my company, and I needed someone to work on my NT servers, I would hire an MCSE, or Novell Servers, a CNE... if I need a Cisco guy, thats what I would hire... I agree that skills should be spread around, but you need to specialize... Not be a jack of all trades... master of none... But instead a master of one, and some knowledge of a few others... A CCIE is a bit too expensive to be fooling around with unix Box configs... But knowledge of different systems wont hurt, but I dont see it as beeing mandatory... Now for the first CCIES... I doubt they have had any pressing need over the past few years to learn or certify in Operating Systems... In fact the first ones, have been held on to by Cisco, and are probobly the ones who came up with things like EIGRP etc... Doubt the company they work for has asked them to modify client systems... - Original Message - From: "Sean Young" To: Sent: Friday, July 20, 2001 9:12 PM Subject: Re: what's wrong with CCIE today?

Want to do unix job, why dont you employ a UNIX Certified Expert ? Before you employ a person, you should ask yourself what are you wanting to do?

Re: Datagram size bigger than 200 get packet loss [7:13166]
Check your interfaces for late collisions. It could be that you have a duplex mismatch and a device that is set for full duplex is stomping on other devices set for half duplex. This is very common when you have devices connected to an ethernet hub. They should all be set for half duplex, and if one of them is set for full duplex it will transmit without checking to see if someone else is transmitting. You didn't say how much packet loss you had, but in the scenario above, the larger the packet transmitted by the half duplex station, the more likely it is that the full duplex station will try to transmit at the same time.

wild guess - heavily utilized links with lots of small packets on the wire. statistically speaking, the bigger packets have more of a chance of problems - late collisions etc. might want to get a Fluke or a sniffer and do some analysis of your network Chuck -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] Sent: Friday, July 20, 2001 6:58 PM To: [EMAIL PROTECTED] Subject: Datagram size bigger than 200 get packet loss [7:13166] Hi All, When I try to ping with a Datagram Size bigger than 200 in a LAN I get packet loss.

Re: what's wrong with CCIE today? [7:13151]
Okay, what is BASIC? Knowing how to change network configuration of windows is basic, because most people use windows on their PCs. If some CCIEs do not know how to configure Unix boxes and still finish their daily tasks, this means to these CCIEs Unix skills are not basic. When you hire them, you should know what they can do, if you want to them to do something they still do not know yet, let them know your requirement and give them time or some training to learn it. All CCIEs know how to learn, this is how they got their numbers. If I am not the administrator of a box, the last thing I want to do is to touch the box without letting the admin know it, we all know this typical story happening to everyone all the time:" You walk into a computer room, put a card on a router, the time you finish this, the router on a seperate rack 30 feet away reboots itself, you are the only one in the computer room, so you, to some extend on your boss mind, are resposible for this."

These guys are CCIE certified. I checked with cisco. Wait a minute, I didn't say that these guys have to configure a Tacacs Server. Tacacs Server is already configured. They just have to restart it and add new users. I don't think it is too much to ask for CCIEs to learn the basic skills set of Unix. It seems CCIEs know how to use Microsoft Windows? Why not Unix? Didn't these guys ever attend college?

Re: what's wrong with CCIE today? [7:13151]
Well, a ccie doesn't know how to fix the NT server; however, he/she does know how change the IP address of the NT server or how to reboot the box right? I would expect that CCIE to be able to do the same thing with a Unix box. He/she doesn't have to manage the Unix server, just know that basic troubleshooting stuffs. To my knowledge, Linux and Solaris x86 are free so those basic Unix skills can be learned very quickly. >From: "B.J. Wilson" >Reply-To: "B.J.

Re: what's wrong with CCIE today? [7:13151]
Come on guys. Everyone's point is very well taken. I am NOT saying that a CCIE also has to be an expert with Unix. All I am saying is that at the very least, have a basic understand of Unix OS so that one can accomplish basic tasks required by the job. I bet that all CCIEs knows how to change the network configuration in microsoft windows but not all CCIEs know how to do the same thing to a Unix system. The point I am trying to make here is that know the basic. I do notice the older CCIEs (#3500 and lower) are very well diversifed with both their Cisco and Unix skills. The newer only know "point and click". >From: "John Neiberger" >Reply-To: "John Neiberger" >To: [EMAIL PROTECTED] >Subject: Re: what's wrong with CCIE today?

Code Red impact on Cisco products - FW: [I] Cisco Security [7:13162]
I received this email from one of the SE's in Cisco's Calgary office. Code Red may impact certain Cisco products. Both Cisco and Microsoft are advertising a fix (details are included below). -Original Message- Most of you have probably seen the Code Red worm affecting Microsoft IIS. As some Cisco software uses Microsoft IIS for the underlying Operating System, please read the field alert to see if you are running the following Cisco products listed below. Please contact your local Cisco SE for help. http://www.cisco.com/warp/public/707/cisco-code-red-worm-pub.shtml Cisco Security Advisory: "Code Red" Worm - Customer Impact Revision 1.0 For Public Release 2001 July 20 12:00 Summary A malicious self-replicating program known as the "Code Red" worm is targeted at systems running the Microsoft Internet Information Server (IIS). Several Cisco products are installed or provided on targeted systems. Additionally, the behavior of the worm can cause problems for other network devices. The following Cisco products are vulnerable because they run affected versions of Microsoft IIS: Cisco CallManager Cisco Unity Server Cisco uOne Cisco ICS7750 Other Cisco products may also be adversely affected by the "Code Red" worm. Please see the Affected Products section for further details. The worm and its effects may be remedied by applying the Microsoft patch to affected servers: http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/ bulletin/MS01-033.asp. This advisory is available at http://www.cisco.com/warp/public/707/cisco-code-red-worm-pub.shtml. Affected Products The following Cisco products are directly vulnerable because they run affected versions of Microsoft IIS: Cisco CallManager Cisco Unity Server Cisco uOne Cisco ICS7750 Cisco Building Broadband Service Manager Other Cisco products may be indirectly affected by the IIS vulnerability (this is not an exhaustive list): Cisco 600 series of DSL routers that have not been patched per the Cisco Security Advisory, http://www.cisco.com/warp/public/707/CBOS-multiple.shtml, will stop forwarding traffic when scanned by a system infected by the "Code Red" worm. The power must be cycled to restore normal service. Cisco Network Management products are not directly affected, but they might be installed on a Microsoft platform running a vulnerable version of IIS. Details The "Code Red" worm exploits a known vulnerability in Microsoft IIS by passing a specially crafted Uniform Resource Identifier (URI) to the default HTTP service, port 80, on a susceptible system. The URI consists of binary instructions which cause the infected host to either begin scanning other random IP addresses and pass the infection on to any other vulnerable systems it finds, or launch a denial of service attack targeted at the IP address 198.137.240.91 which, until very recently, was assigned to www.whitehouse.gov. In both cases, the worm replaces the web server's default web page with a defaced page at the time of initial infection. The worm does not check for pre-existing infection, so that any given system may be executing as many copies of the worm as have scanned it, with a compounding effect on system and network demand. As a side-effect, the URI used by the worm to infect other hosts causes Cisco 600 series DSL routers to stop forwarding traffic by triggering a previously-published vulnerability. Any 600 series routers scanned by the "Code Red" worm will not resume normal service until the power to the router has been cycled. The nature of the "Code Red" worm's scan of random IP addresses and the resulting sharp increase in network traffic can noticeably affect Cisco Content Service Switches and Cisco routers running Cisco IOS software, depending on the device and its configuration. Unusually high CPU utilization and memory starvation may occur. Impact The "Code Red" worm is causing widespread denial of service on the Internet and is compromising large numbers of vulnerable systems. Once infected, the management of a Cisco CallManager product is disabled or severely limited until the defaced web page is removed and the original management web page is restored. Software Versions and Fixes Microsoft has made a patch available for affected systems at . Cisco is providing the same patch at http://www.cisco.com/pcgi-bin/Software/Tablebuild/doftp.pl?ftpfile=cisco/voi ce/callmgr/win-IIS-SecurityUpdate-2.exe&swtype=FCS&code=&size=246296.

Re: what's wrong with CCIE today? [7:13151]
Hmm, maybe the fault lies in companies that only hire people who have a specific set of certifications to manage their networks. I, and for that matter several other non-CCIEs I know, could easily have handled your problem. I'm betting that you never even got the chance to see us, as the insistence on having a CCIE never let us get past the recruiter, HR department, or whoever made the hiring decision. I have met a lot of CCIEs that don't understand the first thing about supporting a production network. In fact, having a CCIE does not guarantee anything to anyone about anything other than you have passed the CCIE lab. If, in fact, your network has mutiple OSPF areas with a non-broadcast Frame-relay WAN, redistribuition of RIP, EIGRP into damn near everything, BGP confederations for three routers, and no static routes ever, the CCIEs would be emminently qualified to support your network. A CCIE number does not guarantee the ability to isolate and correct non-cisco issues, or the ability to clearly articulate a thought to a non-techie person. For that matter, the same can be said for hiring someone on the basis of having a 4.0 GPA, or being class president, or being a friend of your uncle Larry. When looking for someone to support your network you really need to sit down and discuss what that means and having an open mind as to the ability of the person sitting across from you to do the job. Of course, that is a lot harder than calling a recruiter and saying "I need a CCIE to manage my network". - just doing a little "not getting through HR" venting!

Doggone those CCIEs. Shame on them for not knowing UNIX startup scripts. I guess I'll be a step ahead of them if I ever get my CCIE. :) What's wrong with CCIEs today?

Because of this, everyone has to login to the routers and switches via local account. We hire these CCIEs to maintain the network while I am away for a few weeks. None of these CCIEs have any background with tacacs servers running on Unix platforms. As to our problems, the simple to do is just to restart the tacacs process byfirst: "killall tac_plus" and second "/usr/sbin/tac_plus -C /etc/tacacs/tac_plus.cfg" but these CCIEs guys have absolutely no clues. Furthermore, they don't even know how to use editing in Unix (i.e vi or emacs) and ended up screwing up my tacacs configuration files. We have a few employees that need tacacs account but these CCIEs guys have no clues how to addnew users to a configuration file which if anyone has done tacacs on the unix platform know that you just modify the configuration file tac_plus.conf and restart tacacs process.

RE: what's wrong with CCIE today? [7:13151]
While I agree that a lot of engineers could use more Unix skills (myself included), the CCIE in routing and switching does not test skills for running Unix TACACs servers. The CCIE in ISP-DIAL, however, is a different matter entirely since the ISP-Dial CCIE tests the ability to configure Cisco Secure under Windows NT and Solaris. Many R&S CCIEs are not from a carrier background, but many are. When I worked at a major carrier, I never had to configure the Tacacs server. There was a seperate team for that. I did, however, frequently configure Tacacs+ on routers and switches. I have yet to have a single customer request to tunnel X-application through Secure Shell (SSH). A CCIE is not an all knowing being. All that you can really infer from a person's CCIE status is that he/she knows routing and switching reasonably well on the 3600s, 2600s, 2500, Cat 5000s etc. I do think that even though a CCIE (R&S) might not know how to configure a Tacacs server off the top of their head, they should have the skills to research the appropriate documentation, get help from TAC, and configure things given a reasonable amount of time. I would also like to point out that there are many people out there calling themselves CCIEs these days. Did you verify with Cisco that these people are really CCIEs? Why didn't you ask these people about their Tacacs knowledge before you hired them if this was important to you? Finally, this post is off topic. Why is it even posted to a Cisco certification mailing list without "OFF TOPIC" in the subject.

RE: what's wrong with CCIE today? [7:13151]
Sean Not everyone can know everything about all Networking and OS's. You obviously know how your network runs, but is it documented?, and if so, is the documentation in a coherent library format? Sounds to me like this important information may not have passed on during your network turnover to these CCIEs. If you had planed ahead, you would have hired the people with a skill set that matches your business need. Yes, there may be CCIEs that can't do anything but Cisco products, but the assumption that everyone has your exact, and (by the sound of it) diverse skill set. I never would have turned my network over to a group without making sure they had the required skill set, or at least access to a large skill set base. Clarify before you flame!

Re: what's wrong with CCIE today? [7:13151]
You're attributing a fault in "these guys" to a certification which doesn't test on UNIX skills. In other words, they're CCIEs - they know more than you or I do about routing and switching on Cisco routers (presumably). But the CCIE is the *beginning* of an overall understanding of how networks work - it's not the end-all-be-all certification which automatically elevates someone to godlike status, as much as you might want them to be networking gods. This is actually one thing I'm worried about, should I ever achieve the CCIE certification: I don't want some future employer to say "Oh, you're a CCIE, great - come over here and fix this NT server," only to be disappointed to learn that I know nothing about NT! The bottom line is: don't criticize a CCIE because they don't know how to use or manage a UNIX server. That's not what they've been trained to do, it's not what they're certified to do, and if you're smart, you won't hire someone to do UNIX stuff without making them prove that they *can* do it. In other words, quit your bellyaching. ;-) BJ - Original Message - From: "Sean Young" To: Sent: Friday, July 20, 2001 6:14 PM Subject: what's wrong with CCIE today?

Re: what's wrong with CCIE today? [7:13151]
Last time I checked, there was none of the following on the CCIE written or lab: Unix Tacacs Server Configuration X-application tunneling over SSL Would you also expect a CCIE to be able to configure CICS on your mainframe and troubleshoot terminal controller problems in VTAM on your FEP? No, I don't think so. Remember, the first "C" in CCIE stands for "CISCO". Just because it's incredibly hard to get does not mean it's the ultimate pinnacle of networking achievement and there is nothing left to learn. In fact, I relate it to a black belt in martial arts. Those with experience understand that a black belt is yet another starting point, it's not the end of the road. Okay, enough rambling. Time to go home!

Re: what's wrong with CCIE today? [7:13151]
I agree with Sean that a CCIE should be able to perform basic UNIX tasks and be familiar with UNIX as such but this here can quickly become a grey area . Because UNIX and networking are both vast fields in themselves ,expecting one person to be a master of both is not right . I work as a System Administrator and I have worked as a Network Engineer during my past projects . Not to say that I am a master of UNIX , I just know how to find my way through it . And then there are gifted individuals who have been around too long and came from Sys Admin positions and moved to Network Engineer positions .They might have best of both worlds .But remember Sean , you cannot have your cake and eat it too...

In the context of a Frame Relay switch there are two uses of DCE. On the physical layer DCE refers to the end that requires clocking. On the layer two or Frame Relay area of the config the FR Switch needs to be identified as acting as DCE equipment. So a router acting as a Frame Relay Switch can use either DTE or DCE cables.

Re: AGS+ as a frame-relay switch [7:13133]
So what am I looking for within this web page? I was actually looking for a "yes" or "no" answer, and hopefully some insight as to what else I may need to configure on the AGS+. Odd thing is, when I have it configured for normal back-to-back operations via HDLC, it works just fine. No problems whatsoever.

RE: AGS+ as a frame-relay switch [7:13133]
It doesn't matter which end of the cable is dce, as long as you are using a dte-dce cable and the dce end is configured with a clock rate. I have an AGS configured as a frame-relay switch with a csc/4t serial card and HDv.35 dce to Cisco HD60 Dte cables. I also had difficulty getting the confuration to work until I RTFM and discovered that I had to change a jumper on the CSC/4t serial card to place the ags ports in DCE mode.

AGS+ as a frame-relay switch [7:13133]
Apologies if this has already been covered once before. Quick question regarding setting up an AGS+ as a frame switch. Do the cables connecting to the AGS+ have to be DCE in order to get the frame-relay switching to work, or can it still work if the cables are DTE? I currently have DTE cables into the AGS+ and am not getting line protocol to come up, even though the other ends are DCE and I have "clock rate 64000" configured on the other ends.

FW: CodeRed: the next generation [7:13131]
-Original Message- From: Marc Maiffret [mailto:[EMAIL PROTECTED]] Sent: Friday, July 20, 2001 10:48 PM To: [EMAIL PROTECTED] Subject: CodeRed: the next generation The following is a description of a "variant" "Code Red" worm that we have found to be in the wild. Sorry for the rough content but we thought it would be best to get this information out sooner and worry about pretty text formating later ;-] -- In this text, we will be refering to the original "Code Red" worm as CRv1 and the second generation "Code Red" worm as CRv2. This does not preclude further generations/varioations still in the wild, it is just an analysis of the worms we have access to. This information is not currently public. Well, sort of is (we published the disassembly of CRv1, so CRv1 targeting info may be known), but the existance of CRv2 with different targeting has not been verified until now as far as we know. For the evidence surrounding the impetus for this second worm search, please examine Stuart Staniford's ([EMAIL PROTECTED]) excellent statistical analysis of worm hit data. The CRv2 worm has the following charecteristics: second:milisecond randomness added to ip selection process removal of web page hack display (no notice to the end users via a defaced page) All other parts of the worm are the same. (still attacks whitehouse.gov (but the IP address has been blackholed), has time limits/definitions of attack, notworm lysine) The worst part about this means that our original tracking methodology (sensors early in the sequence) is no longer accurate, since CRv2 infected hosts do not contact early hosts, nor reliably contact any point (other than the blackholed IP address that use to point to whitehouse.gov). This means that potentially ALL(ie: global, coprehensive) ids/logs data must be organized and sorted to find infected hosts. The Differences: It has 13 or so pertient bytes changed, adding a time based randomness factor and disabling page defacement. The code had been there all along. It had intentially (we must assume) been disabled in CRv1 , then reenabled near the end of the cycle. There has been discussion that this was a natural progression of the worm code, however, we do not beleive this is the case. From analsysis of CRv1, there seems to be no distinct way to shift the nessecary bytes to generate CRv2. Hence, it is my belief that this is a modified worm, rereleased. It has been posited that the CRv1 was a target aqusition mechanism, gathering data on infectable hosts to gain a high initital base for the following CRv2 infection. The Ip Selection Process: We will display the effecive CRv1(sequence), and the effective CRv2(timebased) ip selection processes. This is a one byte change, at offset 9C2. it changes the storage of some time based computations that were performed in CRv1 but discarded. The new byte changes the storage location from EBP-1B0( a general purpose holder stack var) to EBP - 18C(the location of the ip). This means that the timevars are actively used in CRv2, while being discarded in CRv1. These are the targeting algorithms(complete, as far as we can discern) that are the asm in the CRv1 worm and also in the CRv2 worm. Seeding the "PRNG" for these examples seed is used for ip through the first iteration of the connect loop. the seed does not change between CRv1 and CRv2, but each thread in the worm has a mildly different seed. seed = threadcount(based on 1) * 50F0668D; CRv1: The ipselection process in CRv1 is a simple sequence generator. This caused the early sequences that we noticed and refered to in our (eEye's) initital warning advisory: ip = (ip * 0x0CF3383) + 0x76BFE53; CRv2: The ipselection process in CRs2 is signifigantly more complex. It takes use of time and a whole lot more input operations. In the following secmsec is the DWORD pair of seconds and mseconds returned from GetSystemTime ip = (ip + secmsec*secmsec*0x0CD59E3 + secmsec*0x1E1B9) * 0x0CF3383 + 0x76BFE53 Other Details: Coincidentally, if this isn't general public knowledge, the worm is smart enough to avoid attacking the 127.x.x.x and 224.x.x.x subnets using the following logic after setting the ip. if( (ip & 0xFF == 0x7f) || (ip & 0xFF == 0xE0) )ip +=0x20DA9; the Hacked Page: The second difference between CRv1 and CRv2 is that CRv2 does not deface the webpage of an infected system. It does this by having 12 bytes different from CRv1. When TcpSockSend is hooked(this still happens), CRv2 points this to a basic redirect that performs harmless actions and returns without actually changing any content. Crv1 pointed to a replacement, CRv2 points to basically a donothing function. what is happeinging is that the label "PADDING_BYTES" actually is padding bytes in CRv1(the code does not disassemble to any sane code). CRv1: We've used ida's data feature to show the "padding data" as dwords(instead of a bunch of bytes) CD4 - EB F8jmp short n

RE: Large Collisions on Vlan1 [7:12961]
You need to clear the counters and establish a time frame for this. 19 million collisions isn't a lot in a well loaded switch that has been up for a long time. If you clear the counters and the number increases quickly, you may have a speed or duplex issue or a bad cable. You said this was an ISL trunk so you should manually set both ends at 100 mbps (or 1000mbps if you've got the special card for the 2924 and a good port on the 6500) and also manually set the link to full duplex. -Original Message- From: Kwame [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 19, 2001 12:25 PM To: [EMAIL PROTECTED] Subject: Large Collisions on Vlan1 [7:12961] What does it mean when the "sh int vlan1" output shows large collisions?

Re: To CCIE's without a job [7:12805]
Kidd - another great book if you want to become a network software designer is Computer Networks by Andrew Tanenbaum. The first edition really covered great basic algorithms for the way the protocols were designed to work. (I read the 1st Edition and have the 3rd edition but haven't cracked the cover yet :-( As far as entering the market for work is concerned, you might sign on with a company that designs device drivers, get some experience with developing and supporting network device drivers, then use that experience to lead you into one of the larger networking hardware companies (remember, they have to develop drivers for their interfaces, too). Once you're inside and understand the architecture of network protocol software, you'd have a better chance at moving into a protocol software programming role. -e- - Original Message - From: Priscilla Oppenheimer To: Sent: Friday, July 20, 2001 11:39 AM Subject: RE: To CCIE's without a job [7:12805] > Hi Cisco Kidd, > > Once the market turns around again, my guess is that you will have no > problem finding a job with one of the major networking firms.

RE: To CCIE's without a job [7:12805]
The funny thing is when you combine Music, Programming and Mathematics. I made a Guitar Pascal Unit years ago, and had to figure out the formel for how much a frequency changes when you move up one fret on the guitar. Well, since you have to move twelve frets to reach the next octave, and a higher octave is the double frequency of the lower, the calculation is Frequency * 2^(1/12). If you take 440 (A) and multiply it with 2^(1/12) twelve times, you have 880 (also A) :-) As for book recommendations - I don't know, but try and search for programming and networking together on Amazon.com. And no, I have not tried to connect my guitar to my routers yet, but I can imagine some cool effects with Split Horizon and Load Balancing...

Hi Cisco Kidd, Once the market turns around again, my guess is that you will have no problem finding a job with one of the major networking firms. With a computer science degree and a CCNP, you'll be hot. And that's the best way to get into network software engineering. On the job training! At some companies, college grads start out in software testing rather than development, but it would only take a year or so for you to move into software engineering. And at some companies you could go right into software engineering I would think. I was going to suggest W. Richard Steven's books, but I see you already mentioned that. Douglas Comer's more advanced books are good too. I'm sure others will give you advice too.

I agree with what you said about music and math being correlated, because I play an instrument and math has always come easy to me ( I know that this is not evidence enough for a theory like that, but, it works for me ). My question is what is the best way to get into network software engineering? What books should I read? What courses are most relevant in the undergraduate curriculum? I am trying to complete my computer science degree now and I am one test away from a CCNP. I like networking but I also like programming. I find it hard to commit to one, so I figured I might as well combine the two. So I need some advice on how to enter the market for network software engineering?

Reference material on pings?? [7:13107]
I am trying to find an in-depth guide to pings. I notice with my sniffer that when I issue a ping from my laptop that there are three requests for each reply. Is this normal? Also I want to learn more about the TTL field. Do routers really only decrement it by one as the packet passes through? I just have a few questions about the nuts and bolts of this and probably traceroute also, stuff that isn't in the normal books. I have read the RFC and what I want is not there. I have also looked around CCO quite a bit, and haven't found anything, not that this means that the info is not there. If anyone knows of a good book or on-line source, I would appreciate it.

Re: When booting up i get ATQOHO [7:11261]
Joe, Responding a bit late, but I had exactly the same problem today. Eventually found that I had to use the specific cable, luckily I found one. The difference between the specific cable and a standard rolled cable with two terminal connectors, seems to be that pins 1and 6 are looped on the OEM cable. Pin 1 is not even connected in the standard cisco connectors. I reckon if you can get pin 1 and 6 looped somehow on the switch the normal cable may work. Otherwise get the real cable. The following link has the right cable at Figure A6: http://www.cisco.com/univercd/cc/td/doc/product/lan/28201900/1928v5x/icg5x/c sspec.htm#41267 Watch the wrap.

Re: What do I need to complete a Token ring lab? [7:13092]
You'll need a few token ring devices - a 2513 would be a good choice for a 2nd T/R router (it will allow you to do SR/TLB), and a 2515 would be a good idea too, so you can do SRB. You'll also want Enterprise IOS on those or a couple of other routers so you can practice DLSw. -e- - Original Message - From: Kenneth Woodely To: Sent: Friday, July 20, 2001 7:24 AM Subject: What do I need to complete a Token ring lab?

Systems Affected Systems running Microsoft Windows NT 4.0 and Windows 2000 with IIS 4.0 or IIS 5.0 enabled Overview The CERT/CC has received reports of new self-propagating malicious code that exploits certain configurations of Microsoft Windows susceptible to the vulnerability described in CERT advisory CA-2001-13 Buffer Overflow In IIS Indexing Service DLL. These reports indicate that the "Code Red" worm may have already affected as many as 225,000 hosts, and continues to spread rapidly. Description In examples we have seen, the "Code Red" worm attack proceeds as follows: * The victim host is scanned for TCP port 80 by the "Code Red" worm. * The attacking host sends a crafted HTTP GET request to the victim, attempting to exploit a buffer overflow in the Indexing Service described in CERT advisory CA-2001-13 * If the exploit is successful, the worm begins executing on the victim host. Initially, the existence of the c:notworm file is checked. Should this file be found, the worm ceases execution. * If c:notworm is not found, the worm begins spawning threads to scan seemingly random IP addresses for hosts listening on TCP port 80, exploiting any vulnerable hosts it finds. * If the victim host's default language is English, then after 100 scanning threads have started and a certain period of time has elapsed following infection, all web pages served by the victim host are defaced with the message HELLO! Welcome to http://www.worm.com! Hacked By Chinese! * If the victim host's default language is not English, the worm will continue scanning but no defacement will occur. System Footprint The "Code Red" worm can be identified on victim machines by the presence of the following string in IIS log files: /default.ida?N NN NN NNN%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3% u7801%u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3%u0003%u8b00%u531 b%u53ff%u0078%u%u00=a Additionally, web pages on victim machines may be defaced with the following message: HELLO! Welcome to http://www.worm.com! Hacked By Chinese! The text of this page is stored exclusively in memory and is not written to disk. Therefore, searching for the text of this page in the file system may not detect compromise. Network Footprint A host running an active instance of the "Code Red" worm scans random IP addresses on port 80/TCP looking for other hosts to infect. Additional detailed analysis of this worm has been published by eEye Digital Security at http://www.eeye.com. Impact In addition to web site defacement, infected systems may experience performance degradation as a result of the scanning activity of this worm. Non-compromised systems and networks that are being scanned by other hosts infected by the "Code Red" worm may experience severe denial of service. This occurs because each instance of the "Code Red" worm uses the same random number generator seed to create the list of IP addresses it scans. Therefore, all victim hosts scan the same IP addresses. Furthermore, it is important to note that while the "Code Red" worm appea

OT: Fridays funnies! [7:13095]
still considered rude to drive the U-Haul to the funeral home. DINING OUT: 1. When decanting wine from the box, make sure that you tilt the paper cup and pour slowly so as not to "bruise" the fruit of the wine. 2. If drinking directly from the bottle, always hold it with your hands. ENTERTAINING IN YOUR HOME: 1. A centerpiece for the table should never be anything prepared by a taxidermist. 2. Do not allow the dog to eat at the table, no matter how good his manners are. PERSONAL HYGIENE: 1. While ears need to be cleaned regularly, this is a job that should be done in private, using one's OWN truck keys. 2. Even if you live alone, deodorant is not a waste of good money. 3. Use of proper toiletries can only delay bathing for a few days. 4. Dirt and grease under the fingernails is a social no-no, as they tend to detract from a woman's jewelry and alter the taste of finger foods. DATING (Outside the Family): 1. Always offer to bait your date's hook, especially on the first date. 2. Be assertive, Let her know you're interested: "I've been wanting to go out with you since I read that stuff on the bathroom wall two years ago". 3. Establish, with her parents what time, she is expected back. Some will say 10:00 PM., others might say "Monday." If the latter is the answer, it is the man's responsibility to get her to school on time. THEATER ETIQUETTE: 1. Crying babies should be taken to the lobby and picked up immediately after the movie has ended 2. Refrain from talking to characters on the screen. Tests have proven they can't hear you. WEDDINGS: 1. Livestock, usually, is a poor choice for a wedding gift. 2. Kissing the bride for more than 5 seconds may get you shot. 3. For the groom, at least, rent a tux. A leisure suit with a cummerbund and a clean bowling shirt can create a tacky appearance. 4. Though uncomfortable, say "yes" to socks and shoes for that special occasion. DRIVING ETIQUETTE: 1. Dim your headlights for approaching vehicles, even if the gun is loaded and the deer is in sight. 2. When approaching a four-way stop, the vehicle with the largest tires does not always have the right of way. 3. Never tow another car using panty hose and duct tape. 4. When sending your wife down the road with a gas can, it is impolite to ask her to bring back beer too. 5. Do not lay rubber while traveling in a funeral procession. --- According to a report by the Lovenstein Institute, George Bush has the lowest IQ of all presidents in the last 50 years.

Re: E1 interface [7:12864]
Matt, Note: if the carrier will only give you a G703 (balanced or unbalanced) interface, you may want to order a G.703 network module (NM-1CE1B or NM-1CE1U). In the U.K., we got an X.21 handoff from the carrier; however, the Promina conversion unit they used to convert from G.703 caused us to lose two DS0 channels on the E1. Int this case, the carrier was Concert and the E1's were between France and the U.K. The French side of the circuits were able to give us all channels with an X.21 handoff. So, bottomline, I recommend finding out what the carriers prefers and configuring your router with the appropriate interface to match. I.e. for X.21 and V.35 standard old serial module (NM-4T, WIC-1T, WIC-2T, etc.) or for G.703 use a channelized E1/ISDN PRI interface (NM-1CE1B, NM-2CE1B, NM-2CE1U, etc.). --Jon "Gareth Hinton" @groupstudy.com on 07/18/2001 09:19:49 PM Please respond to "Gareth Hinton" Sent by: [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc: Subject: Re: E1 interface [7:12864] Matt, WIC-1T will do the trick. Just make sure of how the provider will terminate the circuit. You can usually ask to have it terminated as X21 - 15 way D-Type, so a standard CABX21MT cable will do. Another alternative is that they terminate it G703 coax and you use a G703 to X21 converter.

Off topic - Tools for measurement - SLA [7:13087]
Dear all, I would like to deploy some measurements for an IP backbone. The idea is to publish some report giving information about packet loss, latency, availability and other stuff related to SLA. What is the best way of doing this ? Latency and packet loss measurements are enough ? Could you list some good tools for this (a kind of a probe that could helping on collecting e publishing the results to the Web)? I would appreciate your help.

Re: ccie lab study satterlee & hutnik [7:13066]
IMHO, the all in one book is relatively basic, not at the level the CCIE is commonly believed to be. It is, however, useful for getting started in technologies where you might not have that much hands on experience. Just don't stop there . your mileage may vary "[EMAIL PROTECTED]" wrote: > > Satterlee & Hutnik has 2 books: All-In-One Cisco CCIE Lab Study Guide and > Cisco(r) CCIE(tm) Lab Practice Kit > > As far as I know the Lab practice kit complements the Lab study guide.

RE: 2948 - gigabit over copper [7:13074]
Just used some of the GBIC's yesterday. Here is a link to some info : http://www.cisco.com/warp/public/cc/pd/si/casi/ca3500xl/prodlit/1kbs_ds.htm Looks like the 2948 is not supported. - Tim -Original Message- From: johan ericsson [mailto:[EMAIL PROTECTED]] Sent: Friday, July 20, 2001 7:41 AM To: [EMAIL PROTECTED] Subject: 2948 - gigabit over copper [7:13074] Hi! Searching cisco's releasenotes the past few hours and can't find the answer for my question.. so thought I could try here instead. Anyone that can confirm that it is really true that only gigabit over fiber is supported on the 2948 (and not over copper?).

Re: PIX.. [7:13067]
This might help Cisco PIX: The PIX is physically more akin to a router than a computer. It runs on Cisco hardware, using Cisco's proprietary operating system (I believe it's a modified version of the IOS used in Cisco routers), and the only options are how big a PIX box you want. There are various model numbers such as PIX 515, PIX 520, PIX 525, PIX 530 etc., which basically provide more throughput and/or additional interfaces as they grow. The key advantages of the PIX are that it's very fast (100 Mbps +), since it uses custom routing hardware and software, and considered very secure. Later versions have grown beyond simple packet filtering and do provide proxying/profiling support for specific protocols, such as HTTP, FTP and SQLnet. The major disadvantage with the PIX is that it's a pain to administer and log, in my opinion. Like routers, configuration is almost always done from a command line via the console port, which is both inconvenient and user-unfriendly. While a properly configured PIX should be very secure, we've run across many that were inexpertly configured and had pretty significant security holes in some cases. A nice feature of the PIX is that if you want a highly-available configuration, the second PIX only costs about ~20% of the price of the first one. The downside is that it support failover clustering only -- you can't loadshare across two PIXes. (Of course, they're fast enough that you shouldn't need to.) Heartbeats between the two firewalls are carried over a special serial cable, so you can't build geographically dispersed clusters; both PIXes have to be in the same room. (By contrast, we once built a Firewall-1 cluster over two sites 4km apart). Border Manager: BM is something of a niche player in the enterprise firewall market and frankly we've never seen it outside of dedicated Novell shops. It's a proxying firewall, which can theoretically be more secure than packet filtering or stateful-inspection type firewalls but is considerably slower. (Also, if you want to run an application for which no proxy is available, you're out of luck.) On a technical level, BM version 2 apparently had many flaws but BM v3.5 and above are considered quite secure. The key advantage of BM would be that it's easy to tie it into your Novell directory and enforce user-level authentication and security policies. If the client isn't using NDS, I don't really see the point. It's running on Windows NT, which we usually advise against for reasons of reliability and security vs. Unix solutions. An NT server can be hardened, but that takes several hours and should be done by someone who knows what they're doing. The Word document talks about tying the firewall into NT domains, which is a very bad idea: a firewall should always be a stand alone server. (Cross-authenticating a high security server with a low security server provides obvious opportunities for side-channel attacks). That said, if they already have NDS client machines and Novell skills in-house, a properly-installed BM solution may be appropriate. The firewall we usually recommend for high-security environments is Checkpoint Firewall-1, on Sun Solaris or a Nokia network appliance. It's fast (not as fast as a PIX, but we've never had a client with a fat enough Internet pipe for that to become a problem), has good stateful-inspection technology and the ability to proxy protocols when desired, and has a great GUI-based adminstration and logging facility. It's particularly good for enterprise deployments where a number of firewalls and/or firewall clusters can log to a single management station. Fundamentally the choice comes down to the client requirements. Are they looking for high-speed connections and they already have plenty of Cisco expertise? Get a PIX. Do all their client desktops authenticate through NDS? Use Border Manager. Are they looking at a large-scale enterprise wide deployment? FW-1 is probably the best choice. It's not really possible to make a conclusive recommendation without more information on their business drivers and existing environment, but hopefully the above quick&dirty summary will be of some use.
