Connecting two small offices [7:63042]
Great networking guru's: I have not done much in the way of networking small offices together. I would imagine that a private WAN link will be too expensive for the company. What are the logical options as far as setting up VPN between two small offices that have DSL level bandwidth?

Re: Connecting two small offices [7:63042]
In the case of the PIX 501 would you set up a box at each site and make them peers? Or would you set up one office with the 501 and make the other a slave? Or (as I am assuming) is it possible to do it either way?

Re: CID Exam 3.0 [7:48839]
Someone should dig out that Radia Perlman quote from Interconnections.

Darn it. - Original Message - From: Priscilla Oppenheimer To: Sent: Monday, July 15, 2002 12:54 PM Subject: RE: CID Exam 3.0 [7:48839] Dan Penn wrote: Check out the outline on CCO. As far as I know SNA, IPX, and Applecrap, I mean I talk, are still there for CID. And, sir, why do you call it Applecrap? ;-) Seriously, can you provide some technical reasons to disparage it? Perhaps it's still on Cisco tests because the philosophies behind AppleTalk had a big impact on modern desktop protocol design. Also, many universities and schools of all sorts still have large AppleTalk networks. You would be surprised at how many still use it. It's also still used at scientific and graphics arts companies. Many protocol designers admire the pioneering work that Apple did to make networks plug and play. There's a new IETF working group called the Zero Configuration Networking group that credits AppleTalk. See here for more info: http://www.zeroconf.org/ Note that IPv6 has serverless autonegotiation of network-layer addresses which behaves quite a bit like AppleTalk. (It probably won't catch on in many environments which have a DHCP server, but it may catch on in other environments). And how about Microsoft's automatic addressing. (Of course we normally only see that when DHCP has failed, but still Microsoft thought enough of the AppleTalk mechanism to steal it. ;-) And how about service location? TCP/IP barely even has service location, still to this day. Don't you think it's a little silly that we have to find resources with a search engine? There is hope with new protocols like the Service Location Protocol (SLP) and some of the new multicast protocols that let you find multicasting servers. Note that the SLP RFC credits AppleTalk. Maybe some expert told you that AppleTalk is chatty. For one thing, any protocol that tries to automate service location, speed up routing protocol convergence, and quickly workaround connection disconnects is going to be a bit chatty. It's a tradeoff. AppleTalk is no more chatty than Windows Networking or IPX. And you want chatty, how about all those keepalives and hellos that Cisco routers send? Maybe that same expert told you to avoid AppleTalk because it broadcasts too much. That's a myth. It uses multicasts, for one thing, which means a decent NIC driver that doesn't do AppleTalk shouldn't bother the host. The descriptions you see about Chooser behavior are mostly nonsense. The Chooser doesn't send broadcasts. It sends broadcast requests which are forwarded (as unicasts) to each router in the zone. Those routers send a multicast onto their networks in the zone. With good network design, this is no problem. The Chooser doesn't send continually unless the user leaves it open with a zone and service highlighted, which is almost never the case. Then it does send rather often, but backs off after 45 seconds. The problem where it sent the broadcast request packets (which are really unicasts) very often, without backing off, was fixed in 1989. By then, it was too late. The criticism of its behavior (even though already based on misinformation) was entrenched in people's minds.

I do not know what country either your company or Debbie are operating in, however I can only quote United States UCC (Uniform Commercial Code) which applies to ALL transactions in ALL states, whether by private parties or public businesses. Only Three things must exists for a legal contract to exist: 1 - An Offer Debbie's submission of her $100 bid to your system. 2 - Acceptance Your email back to Debbie stating that her offer had been accepted 3 - Consideration When Debbie provided her credit card number to the Pay system, it is legally the same as placing cash in the hand of one of your company's employees. Based on the evidence above, you both continue to have a legally binding contract and in addition, you both have written evidence of that contract (in other words, not a verbal contract) which makes the case very strong. I am not a lawyer and this is based on my personal understanding of the law.

You would want to x out the IP addresses. If it's too much work, just check yourself if header lengths add up. I think the sniffer is complaining that it received more or less data than it expected, based on length fields in the packet itself. It's probably not something to worry about, especially if you're not troubleshooting an actual network problem.

Re: Ghost Server and clients using multicast
Are the client and the server on the same VLAN when you use the boot floppy? I would think they would have to be. Jeff wrote: Does anyone have experience working with a Ghost Server that multicast?

OT: Wireless LANS
As a member of the local chapter of the NPA (Network Professional Association) I have been tasked with an interesting assignment. I need to make the following argument: Anyone who uses a wired network today is stupid! or Anyone who doesn't use a wireless LAN is stupid! (take your pick) This is of course all in fun. I of course want to do as good a job as possible so my question is this.

Re: Wireless LANS
Dale, I think the premise of the argument I am to make is to create a lively "debate" type of atmosphere. Think about it, if I get up and do a boring (or semi lively even) presentation on the pros/cons of Wireless, and do a good job at it, is it really going to be that exciting! I would have to have the presentation skills of Laura Chappell to pull that off :) BUT if I make an insane argument (and the more I delve into it the more insane it seems) it will garner lively discussion and possibly a better learning atmosphere. At least this is what I hope. Everyone, Thank you for responding to this question, I will let everyone know how I did, the presentation is next Thursday. Mike Linehan Dale Holmes wrote: How about "Anyone who makes the argument today that any single technology is appropriate for everyone is stupid!"??? Wireless is cool, and has many applications, but not everybody needs it. There are many situations where it would be impractical or simply inappropriate. I know it is all in good fun, but I am not sure that it benefits anybody to have NPA members practice justifying claims that are simply ludicrous. Why not investigate the top 5 most unexpected wireless success scenarios, or something like that, if you simply want to get people excited about learning new technologies?

SECURITY - SECURITY - SECURITY Three words: ENCRYPTION, ENCRYPTION, ENCRYPTION ;-) How many of us use encryption on wired LANs? Probably not many. But everyone seems to use encryption on wireless LANs, at least 802.11 wireless, which is what I'm familiar with... So that seems like an advantage, not a disadvantage. The disadvantages I can think of for wireless are: 1. It's pretty slow ( 11 Mbps shared bandwidth) 2. Mobile wireless is fraught with issues. How do you get a new IP address when you move from subnet to subnet? (Of course, that's not too straightforward on wired either, come to think of it.)

OT: Full-Duplex vs. Half-Duplex
I was just reading Windows 2000 magazine today (hey no flames here) and an interesting thing came up. A reader asked one of the editors why his network performance was so bad on this one machine. Not going into allot of detail here is a quote from the editor's answer: "A second possibility is that the network adapter is defaulting to full-duplex mode instead of half-duplex mode. Often, enabling full-duplex mode on adapters-even when the network configuration (i.e., switches or NICs) supports it-actually reduces performance." Now maybe I don't know something here, but does this sound like a good answer to you? Full-duplex should provide more bandwidth if configured properly. Wouldn't it be more proactive to try and fix whatever the problem is (if it is the problem) with full-duplex, than switch to half-duplex? What do you think??? begin:vcard n:Linehan;Michael tel;fax:612-888-1355 tel;work:612-888-1501 x-mozilla-html:FALSE url:http://www.cadcamsys.com org:CAD/CAM Engineering Systems;Technical Support adr:;;10850 Nesbitt Ave S;Bloomington;MN;55437;USA version:2.1 email;internet:[EMAIL PROTECTED] title:Systems Engineer note:Opinions expressed are not necessarily those of CAD/CAM Engineering Systems fn:Michael Linehan end:vcard
Re: Header/LanWatch Workbook
Trace, Go to www.packet-level.com. Laura Chappell has a book in electronic format called TCP/IP Analysis or something like that. Now take a little advice, currently she is sending the pdf of all her electronic books: (including introduction to network analysis, TCP/IP analysis, and Basic Cisco Router Configuration) if you order one of her videotaped training classes. Order yourself the Packet Level IPv4 Certificate course for $300.00 and you'll get all three of the electronic books for free. WELL WORTH THE MONEY! Nobody teaches this stuff better.

Isolation
Although this group is great for collabarating...I feel the need for some human interaction. My current job environment entails me as the only network proffessional on staff. Is any member of the list a current member of the NPA? If so, what do they think? Is this worth the $175.00 per year? Are there any other options in the Twin Cites (Minnesota) area?? Also I have a philosophical question. Would it be better to find a position that peripherally allows some Cisco WAN experience before embarking on CCNP/CCIE? I have my CCNA. Or should one just go for it anyway? ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
