Re: VOIP billing [7:38756]
You can use a radius platform for billing in your VoIP network. For small scale you can use the CallManager or Cisco ACS server billing, for the larger stuff you need to use Radius accounting and develop your own scripts to process the records Cheers Pat ""Kiran Kumar M"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Thanks for your reply.

NAT questions-will overlap occur? [7:38764]
I found my previous administrator configured the following NAT for my router (shown below). Our network is in 50.100.X.X and we need to contact a workstation in 192.168.3.X network (192.168.3.1-192.168.3.100). That's why he defined the source pool to be from 192.168.3.101 192.168.3.240 interface Ethernet0 description Interface facing Financial Service Provider ip address 192.168.3.1 255.255.255.0 ip nat outside interface Ethernet1 description Interface facing Rabobank (Trusted) network ip address 50.100.165.240 255.255.255.0 ip nat inside ip nat pool XXY 192.168.3.101 192.168.3.240 netmask 255.255.255.0 ip nat inside source list 1 pool XXY ## Q1)But, when I show IP nat trans. I saw the following, I understand the first two, but not line 3. the 192.168.3.118 should be the source address of returning packet, what is 192.168.3.119 ? RBFW2514#sh ip nat trans Inside global Inside local Outside localOutside global --- 192.168.3.117 50.100.165.81 --- --- --- 192.168.3.118 50.100.165.210--- --- --- 192.168.3.119 192.168.3.118 Q2)I understand there is another kind of NAT which work like the following. Inside global Inside local Outside localOutside global 192.168.2.2:1234 10.0.0.1:1234 172.21.3.1:23 192.168.2.2: 10.0.0.2: 172.21.3.2:23 192.168.2.2: 10.0.0.3: 172.21.3.4:23 What is the difference these method. I think both NAT can work. Why we don't use these one? Q3)But in this method, I found a problem what if 10.0.0.1 and 10.0.0.2 use the same port . There will be 2X 192.168.2.2: in the inside global. Will be 192.168.2.2: have problem identify which to be NAT back to 10.0.0.1 or 10.0.0.2.

IOS MD5 checksum against router checksum. Who to believe? [7:38767]
Hi guys, I have a bit problem with this dilemma and just wondering whether something is out of place. The MD5 checksum on an IOS was calculated correctly to that on display on Cisco's web site. However, when the file was loaded on the router its checksum was different. "Verifying checksum... invalid (expected 0x7081, computed 0x5944)" Now would anybody know whether these checksums are suppose to compliment each other? Other defiling factors: Just loaded another image from the same source, link etc (everything same as previous and all went well). Any ideas guys or is this just one of those wieldos? Regards, George.

RE: compress command unavailable on FR or hdlc intf??.....Why? [7:38770]
Page 314 Remote Access Book. - For HDLC links, STAC is the only available choice. Page 316 - For FRame RElay deployments, use the frame-relay payload-compress command to enable STAC compression on an interface or a subinterface. The reason that you can only use payload compression on a framer-relay interface is becuase the header information needs to remain intact so it can be read by the switches that the transmission crosses.

Re: NAT questions-will overlap occur? [7:38764]
Hi Tong, The second method you use is twice-NAT, both source and destination addresses are converted. This does not work well on Cisco routers unless all NAT entries are defined statically. This is sometimes a good policy anyway where there are only a small number of known connections, which is often the case when connecting to exchange feeds for instance. You have an address clash. Note that a NAT router has only one IP stack and one routing table. You cannot have the same network on both sides of the NAT router. In your case it might be possible to use a /25 mask and use .129-.254 for the pool, however, I would not recommend this without further information from you. Normally I would want to use a NAT pool that was not present on either side of the router. Is there a reason that you are using that pool anyway? Is this dictated by the provider, or are they happy to route to a network that you specify? You need to know how many servers will be contacted within the financial services provider, and how many clients on your network, also which way is the connection made? Is it a persistent connection? Is there any name resolution across the router? rgds Marc TXK "Sim, CT (Chee Tong)" wrote: > > I found my previous administrator configured the following NAT for my router > (shown below).

RE: Appreciate Your Expertise On This Strange ARP Problem [7:38778]
Did you get a chance to take a look at the IP configuration of your DHCP clients? Router A could have been sending out proxy ARP's (like you already mentioned) and possibly ICMP redirects to your workstations. Without the default route, and with the wrong subnet mask, the A router's routing table looks like this: C 10.67.2.0/24 S 10.67.1.0/24 Without the default route, the A router doesn't have routes for 10.67.7.x or 10.67.8.x. If the A router is replying when your workstations ARP for your servers, then your workstations are sending out packets with a destination IP address of your server, but with a destination MAC of the A router's ethernet interface. The A router has routes to your servers, so there's no problem there, except of course for inefficiency. When your servers send replies back to router A however, the router has no route back to your workstations. It did when the default route was in place, but without it the A router has no return path. That sounds far fetched, but I can't think of another explanation that fits your description of the problem. If you find yourself in such a situation again, fire up a protocol analyzer and compare destination MACs with destination IP addresses, and you'll get a better picture of what's going on. hth, Hal -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, March 18, 2002 7:42 PM To: [EMAIL PROTECTED] Subject: Appreciate Your Expertise On This Strange ARP Problem [7:38738] Hi there This is my first time to post a question. Here is a real scenario which happened a few days ago. Though the problem has been resolved, i still cannot understand what the cause is. Customer A has a partner connection to B's network. due to lack of capability on B's Router/Firewall, one of A's router is plugged directly onto B's internal LAN(sounds silly, but it is true). B's LAN use 10.67.0.0/16 address, of which 10.67.1.x is for servers, 10.67.2.x for routers/switches, 10.67.7.x and 10.67.8.x for DHCP clients. B's router has 10.67.2.1 addr. A's router on B's LAN gets assigned an ip addr 10.67.2.2,but a wrong /24 mask was given by B. since A's users need to talk to B's server, a static route(ip route 10.67.1.0 255.255.255.0 10.67.2.1) was added. A default route is also configured(ip route 0.0.0.0 0.0.0.0 10.67.2.1) on the A's router. when this default route was taken off(no obvious reason to point a default route to B's default router), all B's dhcp clients cannot talk to their own servers(10.67.1.x) any more even they are on the same subnet. B's network support was called in, and they found that the A's router is incorrectly answering ARP requests(by default ip proxy-arp is enabled on the LAN interface). and somehow the arp respone reaches the client before the server's, so the client cannot talk to the servers. the problem later was resolved by rectifying the subnet mask on A's router. but i still cannot figure out what went wrong when the default route on A's router was removed. I'll be much appreciated if anyone can shed some lights on this. regards Alec Shi Senior Support Engineer Axon Computertime Auckland NZ -- The information contained in this e-mail message is intended only for the use of the person or entity to whom it is addressed and may contain information that is CONFIDENTIAL and may be exempt from disclosure under applicable laws.

IPSEC UDP [7:38782]
I want to create an IPSEC UDP from one Lan to another via the internet. Going across both firewall and routers, possibly though NAT. I am trying to find out more information on this. I read that some cheap routers using NAT, you can only have 1 IPSEC UDP session, from 1 client at a time, and that is all. Are there any issues like this with a Pix? Is running IP SEC UPD as simple as opening UDP Port 500, and that's all I have to do? Does the 3DES license on a pix come in to play at all when doing this? How secure is 3DES UDP, I know this is a lot of questions, but I just wondered if someone could suggest a book or site...

Re: Is cable network really a shared medium? [7:38705]
Hi Sam, The shared vs non-shared issue DSL providers mention is somewhat misleading. In any residential cable or DSL network, you will have stat muxing. In a cable network, this happens on the HFC network. In a DSL network, this happens at the Agg router (the one that terminates all of those DSL connections). The Internet is one big stat mux. In either the DSL or Cable approach, the customer observed performance will be a result of many factors, including access network design (how many subs share the cable or agg router), the behaviors of these other users, the regional network design, the size and types of peering connections, and where the users are actually surfing too. My house has a long driveway that only I use. Does that mean I'll get to work faster than the neighbors down the street which live in an apartment complex and share a driveway with other folks? In both approaches, one can prioritize traffic or partition bandwidth to certain groups of users. The current standard for how IP/ethernet frames are transmitted over an HFC network is defined via the DOCSIS 1.0 spec. This specification is available at www.cablelabs.com. This spec defines how to support best-effort IP transport. Support for additional features, include QoS, is defined in the DOCSIS 1.1 spec. This document is also available at the above web site. Some details about DOCSIS cable networks: * On the HFC network, a single downstream channel can support ~25-35 Mb/s (depending on the modulation being used). * The upstream connection typically can support between 5-10 Mb/s (depending on modulation and the size of the channel). * The cable operator can opt, based on RF combining, how many homes (fiber nodes) share a downstream or upstream.When service is initially launched in an area, an operator might combine several nodes together and as the take rate increases, reduce the amount of combining (which effectovely reduces the number of customers who share the bandwidth). * When a cable modem is brought online, it gets an IP address via DHCP and then is loaded with configuration information (IP, L2, and L4 filters), network management, etc information. These filters prevent issues which arise when DHCP servers are running in a customer's home, prevents my NETBIOS traffic from being seen by neighbors, etc. There are other technologies still deployed by cable operators to support HSD (LanCity, Motorola CDLP, Com21, etc.) which may not operate the same as DOCSIS. Hope this helps. sam sneed wrote: > > I just changed services from DSL to cable modem.

ospf and sub-interfaces [7:38788]
I'm looking at an design where there's a hub-spoke network based on 802.1q. Specifically, there will be a number of routers connect back via FE/GE into a central router through an 802.1q trunked interface. Each remote router will run OSPF and thus should form an OSPF adjancency with the central router over its respective sub-interface. Any issues or gotchas with this? I've not gotten a chance to test this out yet. Thanks much.

Re: ATM for CCIE [7:38772]
The one book I'm reading is from ciscopress: Cisco ATM Solutions, by Galina Pildush The next question is, How does a cash-challenged individual such as myself set up an ATM lab in his basement? Someone mentioned the LS-100 in a previous message. What are the going prices on that? Also, can I find affordable cards for a low-end router (say, a 2500/2600) to turn it into an ATM switch as we can do for a FR switch. The FR switch command is "frame-relay route"; is there something like "atm route" that enables the switching of ATM circuits from one interface (or subinterface) to another? If so, then we could emulate a service-provider cloud, which we then could access across a standard UNI.

Re: Eigrp not responding to bandwidth commands [7:38744]
In the diagram and configs it's not clear where exactly nw 1, 2 and 3 are, you cut that part of the config out. I know changing the bandwidth works well and quite fast. I have done so in the past for a customer running a 6M ATM pipe and T1 frame relay for redundancy. We needed to work on the router that terminated the ATM so I simply changed the bandwidth to 100 and with a couple seconds all the traffic reverted to frame. If you really only want to test whether changing the bandwidth works simply connect two routers back to back with two serial connections, equal clocks, no distribute lists and then change the bandwidth.

Re: Is cable network really a shared medium?(more [7:38718]
You guys are both right. Cable modem plants are a broadcast network. All packets are sent down the line and you have the ability to see everyone's traffic 'IF' you could sniff the cable line and not sniff the ethernet cable going to your PC. Most cable modems are simply mini-routers so if packets are not destined for you then they are dropped. However, if you could console into your modem (depending on brand) you could change the thing to a bridge. So if your modem was set up as a bridge then you could see all the traffic. And baseline privacy it's great in theory yes. But think about this: When subcribers first get their equipment installed there is no software added to their PC that allows them to de-encrypt the data traveling around the network. So where does the de-encryption happen? The modem and CMTS are what de-encyrpt the data. And in order for your modem to know if a packet is destined for you on this broadcast network it needs to de-encrypt the packet and then drop it. So you are on a broadcast network where all cable modems can de-encrypt all data. If the modem was configured as a bridge and simply forwarded all data to the ethernet port, then you could sniff til the cows come home. Understand that I am a HUGE fan of cable modem services. There are just some small holes that need to be filled. Security is one issue and quality of service at the cable modem level is another- although this can be addressed a little bit by playing with the bandwidth settings in the cmconfig files that are downloaded when the thing boots up. James www.itpapers.com has about 85 papers on Cable Modems. Registration is required and free- except for the occasional email.

CEF/MLS, IOS SLB & Win2K [7:38821]
Hey all. This really a three parter: 1) This may sound stupid, but can you use CEF and MLS at the same time? Reason I ask is because we're using CEF on our 6500s right now, but to configure IOS Server Load Balancing (SLB) one must enable the MLS Flow cache to full (which I did). I recall reading that the MLS flow cache can be used for other (accounting?) purposes while CEF actually handles the forwarding of packets. But I'd like to get some input from others about if this is indeed the case. Even with the MLS flow cache on full, one can do a "show mlw cef" and still see that CEF (seems to be) working. 2) Has anyone here had the chance to work with and configure IOS SLB? I've recently configured it, and it's pretty straight-forward. It seems to work, but I was wondering if anyone had any had any suggestions for tweaking the faildetect and reassign values. We were trying to test it's ability to recognize when a real server is down by disconnecting the ethernet connection to that server, but it didn't seem to take the server "out of service" after the appropriate number of failed SYNs (we have it set for 4). I also have it setup to reassign an IP session to another real server after 2 failed connections but that didn't seem to be the case either. 3) The servers I'm trying to load balance are Win2K servers. One of the configuration requirements for SLB is that you install and configure a loopback adapter at the Win2K machine. The problem is when you do that it creates an bad route (i.e. if the NIC is on a 10.1.1.x network, installing the loopback creates an entry in the Win2K routing table that routes all 10.0.0.0 traffic to the loopback adapter, which keeps the Win2K machine from communicating at all). We can remove the route manually, but it keeps popping back up, so I was wondering if anyone had a method to keep that bad route from coming up. Any input on any of these questions is greatly appreciated! Thanks! Mike W.

SNMP Packet question [7:38824]
Hello group, I am trying to write a script in perl to monitor interface errors and total traffic during work hours. I'm doing an snmpwalk to get the info. I want the total amount of packets in and out of an interface so I can calculate the % of errors on the line. Cisco says on their site : http://www.cisco.com/warp/public/477/SNMP/5.html that ifInNUcastPkts (.1.3.6.1.2.1.2.2.1.12) are counts of inbound broadcast and multicast packets ifOutUcastPkts (.1.3.6.1.2.1.2.2.1.17) are counts of outbound broadcast and multicast packets besides In and Out whats the difference? I thought Ucast meant unicast and NUcast meant broadcast and multicast. When queried, every int gives NUcast and Ucast which are different values. How could Cisco define them as the same. Is this a misprint? Lastly I'm assuming that total packets would be the sum of the 2(unicast + multicast/broadcast). Is this assumption correct? ps i don't want ifOutOctets because i want the # of packets not bytes. thankd Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=38824&t=38824 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Connect the DSL modem to one of your switches, SW1. Connect some of your MS boxes to SW1. Connect the ethernet port of a router, R1, to SW1. Connect R1 to R2 via a back-to-back serial cable. Connect the second switch, SW2, to the ethernet port of R2. Connect other MS boxes to SW2.

Go buy a cheap DSl router from one of those chain stores. You can get one for $100.00 or so. It will do PPoE and simple NAT. Then just put your routers behind them.

Re: Appreciate Your Expertise On This Strange ARP Problem [7:38828]
Alec, This is quite an interesting scenario you ran into. I think I can explain what happened. As you mentioned Cisco enables proxy-arp by default. Usually this is a good thing - in this case it was the cause of the problems. Before the change when a 10.67.7.* DHCP client wanted to connect to a 10.67.1.* server, the client would issue an ARP request for the 10.67.1.* address. This ARP request would reach the actual server as well as the A router. The A router would see that the request was for an address that it believed was on a completely different subnet (10.67.1.0). Since proxy ARP was enabled (by default), the router would answer the ARP request using its own mac address as the destination mac address. At this point there would be a race between the server responding (correctly) to the ARP request and the A router responding to the ARP request. When the server's ARP response won that race, everything worked fine. When the A router won the ARP response race, it would receive the packets destined for the server from the client. The A router would then attempt to route those packets to the correct destination. Its default route said to route them to router B, which it would do. Router B would then know to forward those packets right back out the same interface to the server. In this scenario traffic was taking a strange path, but still working (its likely router B would actually also send an ICMP packet which may have taken router A out of the loop). When the default route for router A was removed, the same race still occurred. Except now when router A won the race it had no route to correctly send the packet. Thus the packets would never make it to router B and/or the server and communication was lost. You correctly fixed the problem, though it would have been interesting to see if disabling proxy arp on router A also would have fixed the problem. My guess is it would have...

I'm doing an snmpwalk to get the info. I want the total amount of packets in and out of an interface so I can calculate the % of errors on the line. Cisco says on their site : http://www.cisco.com/warp/public/477/SNMP/5.html that ifInNUcastPkts (.1.3.6.1.2.1.2.2.1.12) are counts of inbound broadcast and multicast packets ifOutUcastPkts (.1.3.6.1.2.1.2.2.1.17) are counts of outbound broadcast and multicast packets besides In and Out whats the difference?

RE: Bit Swapping [7:38823]
Here is how I understand it: Let's say 0110.1234.5678 is represented on the Token Ring side. Then, 8008.482c.6a1e is the source MAC address as it would be represented on the Ethernet segment. This is because you're going from Token Ring to Ethernet and bit (opposite or reverse) swapping takes place. How is this done? First write out the source MAC address in binary (hopefully, this shows up like I typed it): 011 0 1 23 4 56 78 0001 0001 0001 0010 0011 0100 0101 0110 0111 1000 \ / \ / \ / \ / \ \ / \ / \ / \ / \ 1000 1000 0100 1000 0010 1100 0110 1010 0001 1110 800 8 482 C 6a1e As shown above, bit swap each bit shown by the arrows. So, for example, 0001 becomes 1000 after the swap, 0011 becomes 1100, 0111 becomes 1110, etc. You'll notice that 0110 and stay the same because writing them backwards gives you the same result.

Re: Home Network [7:38818]
You have several choices... Choice 1 (low budget...) have 2 nics in the 200 server... One nic goes to your DSL modem, one to a switch Setup NAT for translation between them (already included in 2000 server...) If your 200 Serv er is the AD Server, and your clients are part of the 2000 domain, then your 2000 server must be the DNS server... Go into the DNS properties, make sure there is no folder in the root called root ( a yellow folder named . ((Yes called dot but with a . not the words))) if this exists, simply delete it... Then go into the properties of DNS and check enable forwarding, and set the DNS of your ISP.

Re: How to monitor the bridging traffic at routers [7:38758]
You could make use of the fact that a bridge just forwards traffic without changing the MAC address, whereas a router decapsulates the packet from the Layer 2 header and re-encapsulates, using its own MAC address. Assuming you have a topology like this: hosts-2500e0--e04000-hosts Do a show arp on the 2500 and 4000. In a routed network, you would just see the other router on the e0 interfaces. In a bridged network, you'll see the hosts' MAC addresses. Priscilla At 02:56 AM 3/19/02, dovelet wrote: >Hi all, > >Our company's network are connected using some Cisco 2500 and Cisco 4000 >routers.

Re: How to monitor the bridging traffic at routers [7:38758]
To reply to my own post ;-), I must mention that the show arp is a good solution in theory, but in practice, it only works with protocols that use ARP (such as IP), and you're probably routing those protocols? Are you on Token Ring? If yes, the show lnm station command might help. If you had something like: hosts-2500to0---to04000---hosts Same theory as before: If routing, show lnm station on the to0 interfaces would just show each other. If bridging, you would see the hosts. Is NetBIOS one of your non-routed protocols? The show netbios name-cache command might help. Are you using transparent bridging? If yes, the show bridge command might help. It shows you the MAC addresses that the bridging software has learned. So, bottom line: learn more about the protocols in use and which ones are routed/bridged. Use appropriate commands based on additional knowledge gained.. Of course, the real answer is the one that you mentioned: get a Sniffer! ;-) You say the network is too large, but with good knowledge of your topology, you might be able to identify a backbone or server LAN where you could place a single Sniffer and get a lot of info.

RE: wan home lab [7:38829]
Given that you are sending channelized data from the 2600, you will need an external CSU for the 2500 to return the channelized data from the 2600 back to serialized data. The cabling between the two CSU's is a simple crossover cable where the pinout is: 1 -- 4 2 -- 5 4 -- 1 5 -- 2 Then you'd need a V.35 to (presumably) DB-60 for the connection from the CSU to the 2500.

BGP Question [7:38858]
Hi all, I am having a BGP problem, and I am not sure how to solve it. Like Jeff Doyle's book says: BGP is not a difficult problem, the problem is the scenario. This is the scenario that I have: --- | I N T E R N E T | --- |Link A |Link B || --- Link E --- | AS 1 | -- | AS 3 | |Link C | Link D | | | I am here| When all links are up everything works fine. The problem is: When Link "B" goes down, there is not any traffic on Link D. In this case Link C gets full and my customer start to call me!. I know it is because there is one more AS hop to reach AS 1, one of the BGP metrics is the amount of AS hops between links. I can manually add one or two prepends for AS 3 and the traffic goes ok, I am taking advantage of Link E My question is: Is there any way that this can be done automaticly?, do I have to use BGP communities? Thanks in advanced, any approach is appreciated.

Hybrid to Native IOS conversion [7:38859]
This is the first question I have posted, I appreciate any ideas or suggestions you can provide. We are following the steps outlined at: http://www.cisco.com/warp/public/473/81.shtml to do the software conversion from Hybrid to Native IOS on our Cat 6506. After step 18 (if you have the instructions to reference) and we tell it to boot from the Native IOS, it comes back up saying that the RP is starting as secondary processor and it is changing console ownership to switch processor. It is supposed to start as primary processor and console ownership should be changed to the RP. All the steps to this point have gone smooth, but it comes up in the SP and we can't continue with the procedures. This process is a first for us and we are still playing with it, but any suggestions/experience you have to share would be appreciated.

I think I can explain what happened. As you mentioned Cisco enables proxy-arp by default. Usually this is a good thing - in this case it was the cause of the problems. Before the change when a 10.67.7.* DHCP client wanted to connect to a 10.67.1.* server, the client would issue an ARP request for the 10.67.1.* address. This ARP request would reach the actual server as well as the A router. The A router would see that the request was for an address that it believed was on a completely different subnet (10.67.1.0). Since proxy ARP was enabled (by default), the router would answer the ARP request using its own mac address as the destination mac address. At this point there would be a race between the server responding (correctly) to the ARP request and the A router responding to the ARP request. When the server's ARP response won that race, everything worked fine. When the A router won the ARP response race, it would receive the packets destined for the server from the client. The A router would then attempt to route those packets to the correct destination. Its default route said to route them to router B, which it would do. Router B would then know to forward those packets right back out the same interface to the server. In this scenario traffic was taking a strange path, but still working (its likely router B would actually also send an ICMP packet which may have taken router A out of the loop). When the default route for router A was removed, the same race still occurred. Except now when router A won the race it had no route to correctly send the packet. Thus the packets would never make it to router B and/or the server and communication was lost. You correctly fixed the problem, though it would have been interesting to see if disabling proxy arp on router A also would have fixed the problem. My guess is it would have...

Re: Whats the difference between Classful & Classless??? [7:38861]
Lets say your network is 170.10.0.0/16. You have a router with a default route pointing at your ISP. Someone finger checks their telnet and tries to connect to 170.10.200.1 and this subnet doesn't exist within your network. With no ip classless the router drops packet. With ip classless the packet will follow default until it gets to your provider who promptly sends it back to you until the TTL expires. You can also do this with ip classless inter e0 ip add 192.168.1.1 255.255.0.0 classful would not recognize the /16 mask as being valid for 192.168.

Re: Whats the difference between Classful & Classless??? [7:38862]
In the simplest terms, one carries a mask (RIP 2, the classless) and one dosen't. If it has a mask, the router knows which part of address is network and which is host. Also, the classful protocol has to rely on the class of the protocol (A, B, C, D, E) to derive the network and host, unless the router has an interface attached to a subnetted network. The best book to learn this is CCIE Practical Studies, Vol 1, as the author does a good job explaining it. Also classless and classful protocols look up routes in the rouing table differently. A classless use the longest match (most subnet bits in mask) to determine best route to destination and the classfull looks up by major network first, then works it's way down til it finds the best match. Also with classless, you can use "ip route 0.0.0.0 0.0.0.0" to create a gateway of last resort. -- RFC 1149 Compliant.

If nothing else, they should draw the guy on the copvers so he fits the techy demographic better: He should have some form of facial hair, JMcL: Facial hair isn't so popular around here - can't say I was specifically checking, but I can't remember too many beards at Networkers, and not many hairy upper lips either. Receding hairlines, however, are a different matter - I notice that not many of the CiscoPress guys suffer from that though /JMcL, he should be slightly overweight, JMcL: Only slightly. A lot of networkers around here are nerdy but fit - perhaps from lugging around those heavy routers? /JMcL he should have a cigarette in one hand JMcL: In the workplace? You've got to be kidding. Serious social (and often legal) faux pas. /JMcL and coffee (or mountain dew) in the other JMcL: or Coke (the drink, not the drug :-). I'm abnormal - I drink strong black tea. /JMcL, and there's no way he should be wearing a tie, especially while trying to troubleshoot a connectivity problem. (Possible exception: the "Ties Suck" tie on thinkgeek.com) JMcL: Agreed, unless it's to be used as an emergency strap for securing equipment in place. /JMcL As for the women on the covers, they should somehow be depicted as presenting the solution for whatever problem the guy is working on, with the alpha male stubbornly ignoring them. JMcL: Naturally! Getting back (sort of) on the original thread, I notice that the (rare) woman on the cover of Priscilla's TDND is the only one RTFM'ing. I'll bet she comes up with a working solution first ;-) I have a sneaky suspicion that the bloke at the laptop is about to start drawing on the screen with his felt-tip pen, but at least he doesn't have a tie. /JMcL (Wonder how many flames I'll get for this one?) JMcL: probably fewer than me! /JMcL Cheers, Hal -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, March 18, 2002 5:14 PM To: [EMAIL PROTECTED] Subject: RE: Who is Priscilla Oppenheimer ?

Priscilla - even a digitised and modified version - has *got* to be better. ;-) (Priscilla's going to be doing a lot of paying out...)

[7:38662] For a real insight into Priscilla, take a look at her interview with Fabio at www.routergod.com. I hear that in addition to her network design work and training she's also doing some modeling for book covers on the side. ;-) (I know I'm going to pay for that later) John >>> "William Gragido" 3/18/02 9:50:10 AM >>> LOL. Hey Priscilla, who are you anyways ;-) What was the name of that book you authored? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of dk Sent: Monday, March 18, 2002 9:51 AM To: [EMAIL PROTECTED] Subject: Who is Priscilla Oppenheimer ?
