Re: Companies requiring proof of previous salary
Hi Then you are truly a good person in your dealings, and commend you for it, and hope that you can continue to practice business that way. But you have to admit, that part of your job is to keep costs down, and you will likely admit that the cost of a resource is a fair amount of a IT budget these days, so it is to your advantage to get the best possible people for the least amount of salary and benefits possible. It is quite likely as a manager that part of your compensation is based on hitting budget numbers, again there is another strike against "fighting for the employee". So the bottom line is that businesses are in business to make money. Everyone that has financial responsibilities in the business has a responsibility to drive profit to the highest levels possible. If you don't the ownership will remove you. It doesn't matter if it is a fortune 500 company that gets killed in the stock market or a small "mom and pop shop", if you are not making money to the owner's expectations, the ownership will make the changes it sees fit to make money. So if a business is in the business of making money then they are not on the side of helping people make more money, have better benefits, better training, up to the point that it starts to cost them money. I once heard a successful business man say to me, while I was working for him, that "XXX was built on the backs of excellent IT people that were too stupid to fight for money, and worked for sh$% wages." Why? Because he could bill them out on contracts for very high rates and pay the employee crap. Frankly I hear lots of IT people say that it is coming time to have a IT union, and based on my last ten years of work in IT, I would have to agree. People are being taken advantage of big time, all of the time. A good example, a manager recently told me that he would never pay a CCIE $100K/yr, that it was too much money for the certification, well we all know that is BS. How about the companies that hire programmers on salary and work them 60-80 hours a week without extra compensation or time off. Or how about the recent bill in the US that is going to exempt IT professionals from overtime time pay. Or my friend that works as a desktop tech and is paid $47K/yr by the job shop, and the contract pays the job shop $108K/yr for him, if a bank made that much money on a loan, they would be committing a crime, loansharking. Now just imagine if there was a general strike of IT workers in the US, the country would grind to a halt in a very short period of time. One can make the argument that IT people should not work in places that act like that, but that leaves VERY few places to work for. One could say that IT people need to stand up for better pay, better benefits, etc, but guess what a company can hold out MUCH longer than the average person can, which means IT people end up take jobs that pay less than they should. Sorry for the ranting and raving, but it really gets my blood boiling when someone tells me that business is on my side, I know better, I have seen too much to ever believe that one, it's kind of like finding out there is no Santa when you are a kid. -- John Hardman, CCNP MCSE+I ""whatshakin"" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > You make it sound like employers are against you...Employers are actually > hoping you are the candidate they are looking for, so they don't have to go > through this: > > Run an ad in a newspaper/online or use a recruiting service.

Re: Companies requiring proof of previous salary
You made some excellent points. I too value a candidates attitiudes as much as their skills. In a large environment it is just as important that folks get along as it is they get the work done. Ironically, harmony faciltiates productive work, and appropriate compensation produces some harmony. - Original Message - From: <[EMAIL PROTECTED]> To: 'whatshakin' <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Sunday, October 08, 2000 10:32 PM Subject: RE: Companies requiring proof of previous salary I do enough of it to know. I am one of the people doing the filtering and it is rough sorting them out. For all of the methods that I have tried to evaluate somebody for a given position, the least reliable information I can rely on is what the last guy thought the candidate was worth. If it were right would we be talking in the first place? When it comes down to money I try to have a picture of what the candidate can bring to the table versus what we need to meet our objectives for the task at hand. It's not easy but I personally lean away from specific skill-sets and salary in favor of attitude, confidence and talent. Good people will do well at anything they commit to and are always a bargain at market prices. On the business side of it though, I'm worried about the money/budget/skill-sets etc that make a project tick. Sometimes it is difficult not to take advantage of the situation to close the gaps in the budget. In reality that makes it a budget problem which is something else entirely. As far as salary histories go I feel that the act of requiring the upper hand in a financial negotiation cuts against the grain of my belief that good business is mutually beneficial to both parties and is to be conducted in good faith.

PIX Question
Hi everyone, There is a web server on the inside of a firewall that is not implementing NAT and the IP address is transparent to the outside world and people accessing the server are using the IP address from browsing which is a security risk (hole). Authentication is through TACACS+ or application server. What is the way forward on this issue considering that the network is isolated from the internal network that has DNS Server, which can resolve the IP address to domain name? Is there a way to specify an alias on the PIX to resolve the IP address to a domain name? _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Re: what'meaning out of band or in-band
Hi, In band signalling uses the same channel uses the same channel for signalling which is used for passing data. For example consider the ordinary telephone in our daily use. The signal is sent on the same wire through which we will send the data also.Where as in outof band signalling we will be using the seperate channel for signalling purpose. Consider for example ISDN, we will be using seperate D-channel for signalling purpose. Hope this helps a little bit. Thanks Subbi.

Turning it off stops the router from sending or expecting LMI. :I believe there is no need to set keepalive as the LMI is taking care of it :right? The keepalive of an interface with frame-relay encapsulation _is_ LMI. :Correct me if I am wrong Can you pass traffic over the interface with no keepalive? No keepalive is a means of forcing an interface into an up-up state from the router's viewpoint even if the interface may in fact be disconnected. While this is useful for test purposes, it doesn't carry any traffic. While the interface shows "line protocol is up" with or without anything plugged in it isn't going to move data from point A to point B. If it _is_ connected, and the other end also is set to "no keepalive", then in most cases you can use it to pass data. However, this is not usually a good idea because the routers will have no means of detecting a link failure (other than timeouts on a dynamic routing protocol). If this frame-relay interface is connected to a real carrier's frame switch, then the "no keepalive" will cause the router to stop sending LMI, which will cause the carrier's switch to show the link as inactive. You may be able to make it work in a lab situation with no keepalive on a router configured as a frame switch, but it isn't a good idea. As a rule, keepalives are a good thing on an active interface passing real-world traffic, and turning them off should not be necessary to bring the line protocol up. -- Jay Hennigan - Network Administration - [EMAIL PROTECTED] NetLojix Communications, Inc.

As noted by the others, I would seriously consider this request under the guise of the company and position. Unless you have verbally told them your current salary there is no reason to provide this now - and if you did provide a verbal on this information then either they don't believe you or their policy doesn't believe you. Either way, trust is hard to earn when it has been lost. With the market s hot right now, this is too much.

Re: Bridge Table
If you're talking about a transparent bridge, then it builds the table based on the frames it receives. If the frame comes in on a certain port, it will associate that MAC with that port. The destination MAC is compared to the table so it will know where to send, but it doesn't use the destination MAC to build the table. And as with most everything networking, Cisco has this information on CCO UniverCD. http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/transbdg.htm Mike --- FRS <[EMAIL PROTECTED]> wrote: > Hi, > > When a bridge comes online for the first time, does > it use the source MAC > addresses or the destination MAC addresses initially > to build the bridge > table? > I cannot seem to find this answer on CCO or Caslow. > > > > **NOTE: New CCNA/CCDA List has been formed.

Re: Companies requiring proof of previous salary
I strongly disagree with this. Previous salary says a lot about how valuable your last employer thought you were to them specifically and how much they felt they could pay you and still keep you. Almost all employers would probably counteroffer you if you said you were going to leave. My last two did, by upwards of 20%. Does that mean my skill level jumped 20% right after I decided to leave and they decided they wanted me a little more? Why should my new potential employer pay me based on what someone else thinks I'm worth? Why should they leave their business decisions up to someone else? My last company thought of me as a cost center. I was there to support their network. My new company, where I am a consultant, bills me out at $200/hr (pays me nowhere near that much... heheh) and definitely considers me a profit center. I bring them money and they in turn think of me as more valuable. Did I jump skill level from the last day at my last job and the first day of my new job no. But my value to my employer did. And that's what counts. Mike --- whatshakin <[EMAIL PROTECTED]> wrote: > Previous salary says a lot about a persons skill > level.

RE: Help!!!!!!!!!
David, I am able to ping with data size 100 and bit pattern 0x, but when I change the data size to 1500 with bit pattern 0x I cannot ping the destination. Is this bcause of carrier problem?

Re: PIX Question
I'm not sure I understand what you're trying to do. It sounds like reverse dns, but I'm not sure why you'd want to do a reverse fix-up. Why not just implement the reverse entry in your DNS server? and don't worry about the PIX. I suspect what you want is: 'www.mydomain.com' to resolve to 12.x.x.x for the internet (the outside) and 192.168.x.x for your local LAN (the inside). Check out the ALIAS command. It is for this exact purpose. Rodgers Moore, CCDP, CCNP-Security Design and Security Consultant Data Processsing Sciences, Corp.

[Fwd: pix netbios resolution]
John Can u help ? I have two Windows 98 machines, one on the inside interface and one in dmz1. How do I workgroup these machines so when i open up network neighborhood the machines appear in the browse list? The summary of my request is simply to workgroup two machines across the Pix firewall using TCP/IP only. I have two conduits that are configured to allow all TCP and UDP traffic to pass between networks. I can succesfully ping, http, ftp, telnet between networks but when I attempt to resolve a NETBIOS name using NBTSTAT (windows Netbios tool) all I get is 'HOST NOT FOUND'. From this it appears that NETBIOS is not being broadcast between networks. What solution is required to allow NETBIOS to propagate correctly? Is there any IP helper function on the Pix, and if so would this do the trick? I look forward to your reply Kindest Regards cheers waheed
PIX Question
Hi Everyone, There is a web server on the inside of a firewall that is not implementing NAT and the IP address is transparent to the outside world and people accessing the server are using the IP address from browsing which is a security risk (hole). Authentication is through TACACS+ or application server. What is the way forward on this issue considering that the network is isolated from the internal network that has DNS Server, which can resolve the IP address to domain name? Is there a way to specify an alias on the PIX to resolve the IP address to a domain name _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

ATM question
Will the cisco 7206vxr support FRF.5 Frame Relay-ATM Interworking function, which enables Frame Relay voice or data traffic to be encapsulated in ATM cells. If so does this mean I could map Frame pvc's within the atm ds3 interface on the router to talk to frame sites of mine? On the satellite end will the telco provider give me the frame traffic in ATM format and simply not de-encapsulate their ATM cells when distributing traffic to my 7206? **NOTE: New CCNA/CCDA List has been formed.

Re: Companies requiring proof of previous salary
Rule 1: You are only worth what it costs to replace you. Rule 2: There is ALWAYS someone willing to do more work for less money. On applications, it normally asks salary at each position. I typically list the range of my present position. I am normally willing to provide a copy of my present job description, and the HR document that show the salary range for the position. (depending on where I am in the scale) It boils down to the point where your skills are more important to one employer than another, and that employer is willing to show it. For me to leave one job and go to another, so same responsibilities and same pay, there must be something extremely wrong with my present employer. On the other hand... moving to a new job often means new responsibilities and challenges. If I am happy where I am, the potential employer needs to provide an incentive for me to leave... and to do that I typically I look for at least a 10% - 20% jump in pay.

Re: [questions about vines]
sorry to say to say that you're very wrong... Banyan Vines has been supported way back to version 10.x and probably earlier (too lazy to check) The trick is, your IOS has to run Enterprise to support native Vines. However, Vines supports encapsulation in IP and therefore both servers and clients can use IP. Therefore the much more expensive Enterprise IOS can be avoided. However, this also depends on what version of Vines you're running. Using Enterprise also has memory requirements for the router as well so if you can use IP it's better all around. (except maybe the little extra overhead on the server for encapsulation/de-encapsulation) Vines and Cisco go back a long long way.

I like _Practical Queueing Analysis_ by Tanner. There are others, but unfortunately I am blanking on the author and title -- something like WAN Design Handbook. Kleinrock, especially Volume II, is the classic, although rather dated. Mischa Schwartz is another, as is Bertzas & Gallagher. Spohn's Data Network Design also has material. Be aware, however, that connectionless networks do not model as well as telephone networks. Work by Will Leland (Bellcore, Telecordia, etc.) showed that Internet traffic distributions are fractal rather than the exponential generally assumed. Depending on what you are trying to do, however, you can simplify a packet-carrying to Erlang B if the policy is to drop packets when the link is busy, and to Erlang C when there is buffering. Not the most scientific thing in the world, but worthwhile for first approximations. **NOTE: New CCNA/CCDA List has been formed.

VPN, BGP & Redundant Network
Hi all, We are trying to add redundancy to our network. There are all sorts of ideas on the table. One of the ideas is to have each of the remote sites (all 7 sites within US) connect to a local ISP and use VPN when needed to backup the frame-relay links that are inplace now. We use VPN extensively for our clients to connect to us now. I am new to BGP, and hence the question: does BGP play a role in this scenario and more importantly is this solution possible in your opinion.

TCN BPDU confusion
Title: TCN BPDU confusion I'm reading the Cisco LAN switching book (great book)! I've got a question about topology change notification BPDU's. If you have a port on a switch that is NOT using portfast with say a workstation or server connected. When that port comes up spanning tree will run. My question is once it goes into the forwarding state will a TCN BPDU be sent? There are three rules that say when a TCN BPDU will be sent. The rule that I think applies is "When a port is put in the forwarding state and the bridge has at least one designated port." I realize most of the time you would want to use portfast in this situation since you don't want to be running spanning tree while the machine is trying to booting up. I just didn't realize you would actually be saving traffic on your network and also the effects of having to flush the CAM quicker. Someone could actually tweak the STP timers down so they wouldn't have to use portfast, but you could have a flood of TCN BPDU's every morning.

Re: TCN BPDU confusion
In my experience you would always want to turn portfast on in end point segments especially those simply connected to workstations and servers since they shouldn't be participating in creating ne type of bridging loop issues "Rampley, Jim" wrote: I'm reading the Cisco LAN switching book (great book)!

RE: Advise....Should I purchase routers ? How do you study for an exam?
I guess it depends on what you do in your work environment. If you work with Cisco routers and switches during the course of your duties I would say that you should be able to fill in the blanks through book study. If you do not get to touch equipment at work you might want to buy a couple of older (used) Cisco routers, possibly 2500 series. If you are familiar (comfortable) with Ethernet look for routers with token ring interfaces and get a token ring hub (you need to have some understanding of token ring anyway, and the token ring stuff seems to be quite a bit cheaper given the lighter demand). In my opinion a couple of cheap 250Xs with token ring and BRI interfaces would work great for CCNP study (my guess is that you will have to buy NT1s for the BRI interfaces). Just my .02.

RE: Ethernet Trivia
Come to think of it, despite my last response, bits don't occupy space, at least not in theory. Manchester encoding, used in ethernet, signals a bit as a one or a zero depending on the instantaneous change in voltage from +1 to -1 or -1 to +1 volt. The time spent at a particular voltage is just that, time spent. The bit itself is signal with the voltage change, which in theory is instantaneous. Of course, in reality there is no such thing as a square wave. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of whatshakin Sent: Saturday, October 07, 2000 1:23 PM To: [EMAIL PROTECTED] Subject: Re: Ethernet Trivia Comments inserted. - Original Message - From: Jay Hennigan <[EMAIL PROTECTED]> Newsgroups: groupstudy.cisco To: <[EMAIL PROTECTED]> Sent: Saturday, October 07, 2000 9:14 AM Subject: Re: Ethernet Trivia > On 7 Oct 2000 01:20:43 -0400, whatshakin <[EMAIL PROTECTED]> wrote: > > :This makes it sound like there is actually something tangible being put on > :the wire.

Re: Load
It means, (assuming that your bandwidth is set correctly), that you are using 9 /255 percent of your available bandwidth. (Weighted five minute average.) 9 divided by 255 is 0.03529... or 3.5% of the available bandwith. The BW parameter says this is a 128Kbps connection, so back to the calculator... 3.5% x 128kbps = 4.48 average kpbs for the last 5 minutes.

RE: CISCO SWITCH
Ummm...I don't understand how you can provide a switch failover solution at the access layer. So, if you have a 24-port switch, with theoretically 24 workstations plugged into it, you want it to failover to another switch if it fails?

Also, I pointed my advertised address at Null0 so that there would be a route in the table. They are telling me that all the traffic will be dropped at the router.

RE: Ethernet Trivia
Them's fightin' words, but I'll ignore that. The discussion is an ethernet discussion, therefore Manchester encoding is the correct physical layer protocol to refer to. The discussion was reaching some rarefied levels, so I felt comfortable throwing in the encoding concepts. Bits are a mathematical concept. "Binary digits." In that sense, they are intangible, and not wavelength, as is any number concept. (I'm not really sure what you mean "bits being wavelength." That discussion was on bits occupying line space.) Bits arose as a discussion concepts when the definition of "get there" was called into question. If by "get there" we mean the arrival of the first tiny little iota of information, then 10BaseT and 100BaseT arrive at the same time. If by "get there" we mean usable information in the form of a packet or frame, then 100BaseT gets there first. Follow the thread, and I hope you will see that my comments fit in, just a day later than the weekend warriors. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Frank Wells Sent: Monday, October 09, 2000 3:38 PM To: [EMAIL PROTECTED] Subject: RE: Ethernet Trivia Lets not make this any more complicated than it needs to be.

Because to me, two separate NICs with different IP addresses isn't a failover. If this is the case, ANY switch should do the job because the failover is actually occuring at the server, not at the switch...correct?

Javier, I dont know the exact port #'s that they use, but they easiest way (and probably best way) to control access is to deny everything except the ports that you want to use. Such as 80 (http), 443 (SHTTP), 53 (udp dns), 21 and 20 (ftp). Also, if I am correct, Napter runs over port 80 (http) and you can't block it at the router without cutting of web access.

Re: MAX. VLAN's
According to my CLSC manual, a Cat 5000 can support up to 250 *active* VLANs, and up to 1000 all up. A Cat 3000 supports 64 VLANs, and a Cisco 7000 router supports 255 VLANs.

A better solution is a Switch with built-in failover. I.e. redundant Power supplies/Pocessor Cards.

Re: Load
Further to the info below - if there's only a single load given (as below), then it refers to the outbound load. I believe some later versions of IOS give load for both outbound and inbound directions. If you don't want to do the maths below to work out the Kbps, you can always just look further down the 'show int' display, to where it says something like... 5 minute input rate 16000 bits/sec, 7 packets/sec 5 minute output rate 2000 bits/sec, 5 packets/sec The input rate and output rate displayed should be accurate even if your bandwidth is configured incorrectly. The load figure is calculated using the bandwidth configured on the interface - if that's wrong, the displayed load will be wrong.

Re: ATM... Why not STM? (just for fun)
ATM isnt really Asynchronous, its Synchronous but it fills in any blank bits by filling them in with blank cells, which are ignored at the other end (except it keeps it all nicely synchronised even though the data is bursty). Incidentally Synchronous systems are usually faster because both ends know exactly when they are going to recieve data, so they dont have to listen out for it. TTFN Lauren [EMAIL PROTECTED] wrote: I was "told" that synchronous transmision is usually faster than asynchronous because there are less steps in it's sending process. Cool, still with me?

RE: CISCO SWITCH
Shore Microsystems makes a "Autoswitch", which dual homes to two Access-layer ethernet switches. Workstations are plugged into the autoswitch, which uses a voltage censor to detect link failure from either of the Access-layer ethernet switches. The autoswitch then uses physical relays to "autoswitch" the workstation connectivity to the alternate Access-layer ethernet switch.

If you can explain it, that would be great. (The other articles did make sense. Thanks for the URLs.)< I was hoping you wouldn't ask that :-) In all seriousness, I was more than just a little confused by their terminology. Of course, this has to be taken in the proper context, coming from an organization that refers to TCP as the "Transport Control Protocol" ;-) I did a quick search at MS to see if there were any tell tale clues. These links seem to be indicative of a methodology of software engineering to inject a portion of code to solve a given problem: http://support.microsoft.com/support/kb/articles/q265/1/12.asp http://msdn.microsoft.com/library/periodic/period98/extreme0598. htm http://msdn.microsoft.com/library/welcome/dsmsdn/rivard_qa.htm Of course, I wasn't 100% satisfied that it was totally correct, so I did a little bit more hunting and came up with the word usage from Paul Maritz, an old timer from MS :-) He left me with the impression that "re-plumbing" is the fine art of going in and fixing code to make it well again: http://www.microsoft.com/PressPass/exec/paul/09-13webdev.asp Undeterred, I pressed on...I then started to realize, maybe this was bigger than MS. Maybe this was somehow an open standards based term that I had not heard about previously. With cursor in hand, I went to the Internet Encyclopedia at this location and did a word search for "plumb" : http://www.freesoft.org/CIE/search.htm Finally, the end was in sight. There were three hits and out of a hunch, I opted in for the hit that yielded "100%". What do you know, but this was the the final definitive word on the subject. Quoting from RFC 2324, "Hyper Text Coffee Pot Control Protocol (HTCPCP/1.0)": 7. Security Considerations Anyone who gets in between me and my morning coffee should be insecure. Unmoderated access to unprotected coffee pots from Internet users might lead to several kinds of "denial of coffee service" attacks. The improper use of filtration devices might admit trojan grounds. Filtration is not a good virus protection method. Putting coffee grounds into Internet plumbing may result in clogged plumbing, which would entail the services of an Internet Plumber [PLUMB], who would, in turn, require an Internet Plumber's Helper. Checking paragraph 9 of the same RFC yielded the reference for PLUMB. It was indeed Bob Metcalfe, the consummate Internet Plumber and prognisticator of all things networking. In short and to recap; I have absolutely no idea what they meant 8-) v/r, Paul Werner p.s. When I get a free moment, I want to share a story for the group about the use of subnet zero on Internet hosts and Internet Gateways and mention why it is *still* a good idea *not* to use subnet zero on Internet host addressing.
