Re: IP Access lists

[whatshakin]

Actually, that would depend on whether or not you are filtering incoming or
outgoing traffic.  There are no hard and fast rules, just recommendations.

Re: Cisco 2620 as a Firewall??

[whatshakin]

If you add the Firewall Feature Set to the 262X you essentially have a
firewall.   This actually gives you all of the functionality of the PIX and
more, but of course the drawback is throughput.  Bear in mind that when
configuring them from scratch, the PIX has a default configuration of being
completely locked down which is completely opposite from a router.  Get your
access lists in place before putting the firewall router online.

Re: Frame Relay Problem

[whatshakin]

Sounds like all you need to get your branch traffic to the next hop (hub
router) where the hub router will route it for you because it knows of the
routes to all destinations.  You could use static routes or route maps with
the next-hop parameter to do this.

Re: annoying line after config t

[whatshakin]

You are exactly right.

Perhaps your previous statement did not come out on paper as it did in your
head...I quote "I suppose there are situations where you may want
lookups -such as when you are using a host file so you can telnet to
different routers using a pneumonic rather than an ip address"

Lookups refers to DNS lookups I presume.  Typically, one uses either hosts
files or DNS to find name to address mappings, just not both at the same
time.  That said, I have used both methods simultaneously when
troubleshooting various problems.  The ip domain-lookup command will force
your IOS to use DNS for name resoution.  Your router will use the entries in
the internal hosts file regardless of whether you have lookups enabled or
not.

PIX IOS upgrades and registration questions.

[whatshakin]

OK guys,
What's the deal with the PIX licensing structure 
and IOS upgrade process?  Looking on CCO, I found docs that mention needing 
to register with TAC to get IPsec functionality in your PIX.  Does anyone 
know whether this registration costs money?  The reason I ask is I am 
contemplating buying a used PIX off eBay and I want to be sure I can 
get IPSec functionality without it costing an arm and a leg...the PIX will 
cost me enough already!
 
I need to know that if I purchase say a PIX 520/515 
with 4.X IOS, what the cost will be to upgrade it to 5.X with IPSec 
features?  This will be the deciding factor of whether I buy one that has 
everything already (means waiting until one shows up) for buying one right 
away and upgrading it to get the features I want.
 
Thanks a lot.

Re: access-list for DDOS attack

[whatshakin]

The three parameters are Average Rate, Normal Burst Size and Excess Burst
Size respectively.

AR= Bandwidth throughput allowed before the traffice is limited by the NBS
and BS parameters.
NBS = Number of bytes accepted in a burst above the AR limit before some of
the packets get dropped or reclassified etc(exceed-action...).  Those
packets that get dropped are measured in a similar manner to those limited
by RED (Random Early Detection).
EBS= Number of bytes accepted in a burst before ALL packets are subject to
your rate limits/measures.

This kind of functionality is what QOS uses and you can find some good
material on CCO which will clarify things succinctly.

Note: I cannot imagine a scenario where you would need to put rate limits on
ICMP traffic, but I would certainly like to hear of one...

Re: Need help setting up Teltone Isdn Demonstrator

[whatshakin]

The NT1 turns the 4 wire S/T reference point into a two wire connection
point.  I am certain there are additional services the NT1 performs, but I
am not sure of what they are.  It will take an ISDN guru to answer that, and
I don't qualify...yet  :-)

To physically connect the routers you just need regular cat5 cables between
the S/T router interface and the S/T port on the NT1 and again regular cat5

Re:

Copy your image to a PC with Hyperterminal and use xmodem to copy it to your
flash.  It takes a while (1-4 hours depending on the size of your image) but
it works fine.

I haven't tried this but I would hazzard a guess it works:  Get another 25xx
series router, take your flash out of the 2504, put it into that router and
TFTP your 2504 image to it.  Then swap it back again.  May save you a lot of
time.

If you try the latter, let us know if it worked.

i previously wrote about my problem concerning IDSN calls which

the reason why i would need this connection is -
my cisco 2504 does not boot with the 2 serial
interfaces which are on it. only with the
BRI and TokenRing Interface.
that`s -because i did a software update !
now i would like to download the old image
from a tftp-server. i need about 6 MB but
the call disconnects after about 4 MB.

can anyone give me an advice ?
( i do not have a token ring device !!)

Re: xmodem software

[whatshakin]

Copy your IOS image to a PC which has Hyperterminal.  You can run xmodem
from there without anything more needed.   Before you resort to xmodem
though, I suggest you see of your router has the 'dnld'  command available
in ROMMON, and use a TFTP server to download the image if possible.  It will
save you a lot of time, mark my words.

Re: Which IOS do you run in your lab?

[whatshakin]

If you can afford to drop a wad of RAM in all your routers then go with
12.1, it has everything the older versions have and more.  If your like most
of us though, you settle for 11.2 or higher.   I end up swapping DRAM and
IOS versions between routers so I can run whatever version of IOS I need for
a particular scenario.

-
Telnet access is usually used to prevent unauthorized access to the
router/switch.  Often, nobody but the senior network engineers will get
access to the internetworking equipment consoles.

Both Radius and Tacacs+ are configured so they only accept the configured
access.  Typically the authentication servers will have something like
Tacacs/Local to allow the routers local username/passwords database to be
used in the event the Tacacs server is unavailable.  Authentication methods
are parsed in the order they appear in the command.  If there is a 'deny' by
any method the authentication process stops...period and nothing will cause
it to move to the next method prematurely.
--

If you have other authentication methods configured in your AAA command,
they will be used.  Otherwise you are SOL.

>

> commonly deployed in a given network?

One Radius/Tacacs server can handle thousands of users.  However, I would
suggest using more than one server with more than 100 remote access users
for redundancy sake.  You don't want to find yourself typing hundreds of
username/password combos into a NAS servers local database after your AAA
server takes a dive!

>

Typically the NT user database or the Novell NDS database would be used in
authenticating a sizeable network.  That said, you probably wouldn't want
users having to get authenticated on servers over WAN lines if possible,
unless the remote site was too small to justify spending
25K on a nice CiscoSecure ACS server and a decent NAS server!

4500 network module not being seen.

[whatshakin]

I just installed a dual port token ring card in my 
Cisco Pro 4500.  The system does not see the card on boot up.  There 
should be enough memory to see it.   IOS is 11.X.  I am currently 
searching CCO to see if I can get some more info on troubleshooting etc but I 
thought I would run it by you lot because one of you probably has the answer off 
the top of your head!
 
Am I forgetting something obvious?
Help appreciated.

ATM references

[whatshakin]

What are you guys reading in the way of 
ATM, bookwise, to prepare for CCIE written?  I have got a lot of Cisco 
related books but none of them have much on ATM, and what there is, is 
pretty poor.
 
The Cisco Press ATM Solutions book is due out next 
month, but I would like to get some good references right now.  I know CCO 
has plenty of material, but I don't care to read off the computer for long 
periods, and my printer is on the blink right now!

Re: Network neighborhood

[whatshakin]

The node only tells the clients in which order to search name resolution
resources like DNS/WINS?LMHOSTS?HOSTS etc.  It will make no difference as to
whether or not a client can actually see a partial number of computers over
a network unless one or more of the name resolution resources is
misconfigured.  For 95/98 clients, this is a parameter handed out by Windows
NT DHCP servers as part of an IP address lease.  I believe it is a reg hack
in NT clients.

Re: Network neighborhood

[whatshakin]

If your are running multiple subnets it could be your subnet masks too.
Make sure your DHCP server is handing out the correct masks to its hosts
etc.

Re: Hand over the domain with the phrase "cisco" to cisco.com?

[whatshakin]

It is not illegal to have the Cisco name in your domain name unless you use
it for Cisco Systems content.  After all, there is a Cisco fish, drink, city
and kid to name just a few, and none of those are in violation of the Cisco
Systems trademark.

Tell them you'll hand it over for $10K or a free Catalyst 8500 if they want
it that badly!  :-)

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.

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.

Are all employers against you? I think not. But some are. They are best
avoided.

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.   In my city, I
get hundreds, sometimes thousands of responses.  Wade through the resumes
initially looking for the usual B.S (experienced in X...been working since
Y(not really experienced)), and also pruning the idiots that cannot even
bother to get their resumes to a professional level.

This usually weans the resume pile by 90%.

Read resumes again in more detail looking for those skills that match what
we are looking for.

Begin scheduling technical interviews and spending time with those
candidates that are/were good at B.S*ing and those that are legitimate.

Numerous hours/days later we have a handful (if lucky) of potential
candidates.  Schedule the second round of interviews to test inter-personal
skills and hopefully get to within two or three candidates.   From the
remaining candidates, if any, schedule third round interviews and get down
to the nitty gritty of money and benefits etc.

A month or so after beginning we may finally get some decent help...

Most employers are more than willing to pay well the candidates that have
what we want.  If you only have a couple of years experience though, you
must realize you are not going to get more than $50K.  No way.

Wouldn't it be nice if the perfect candidate came walking through the door
every time you needed one?  Doesn't happen, instead we have to go through
that crap.

Re: Companies requiring proof of previous salary

[whatshakin]

Prospective employers should definitely not leave it up to the previous
employer to determine what a person is worth.  However, they should use it
as a point of reference.   If your last employer does not or will not pay
you what you want, it begs the question 'Why?'.   There are really only a
few answers that apply:

Employee does not want to stay for whatever reason.

The task(s) they perform are not worthy of X dollars.   Outgrown position,
low skill level etc.

They are happy to see you leave.

Based on these scenario's, the only ones that springs to mind as valid
reasons to warrant a significant pay hike are an employee wishing to leave
because they are bored and need more of a challenge, or because they are
significantly underpaid.  In either case they would also need some sort of
proof of increased worth.  Diplomas and Certs are two possibilities that
fall into this category.

It comes as no surprise to anyone that counteroffers are normally made to
employee's of value that have expressed their desire to leave.   This is
also factored into the offer your potential employer will make.

The whole Consultant/Corporate-body scenario is just basic business
economics.

Re: Companies requiring proof of previous salary

[whatshakin]

Previous salary says a lot about a persons skill level.  After all, if you
are not worth your former or current employer paying you what you are asking
for, why should another employer pay you that much?

Granted, it is a well known fact that many employees often do not recieve
the benefits they deserve if they remain at one company for more than five
years or so.  However, your salary is probably not too far off what a job
change will get you.  This being the case, it should not be too embarassing
telling your prospective employer what you currently make.  If it is, you
are probably not worth what you are shooting for.

There are exceptions to the rule.

The physical length of a signal is not inversely proportional to its
frequency.  It differs depending on the line encoding.   Again, a bit is the
term applied to the signal state.  Signal
states occupy line space.

This is quite a good hypothetical scenario, and is indeed correct.

Your formula is correct, however, it does not apply very well to finding
delay propogation over a wire because of the numerous other factors which
need to be applied additionally.  IE: The properties of the wire medium,
EMF, block coding, IFG, protocol overhead...

Re: Ethernet Trivia

[whatshakin]

What you are describing is not the bit, it is the encoding.  Bits are not
actually on the wire.  The actual bits of tangible data are only generated
on the hosts at either end of the connection, and any internetworking device
between links that needs to store or regenerate the signals.  Everything in
between is just signals.

Re: Ethernet Trivia

[whatshakin]

This makes it sound like there is actually something tangible being put on
the wire.  Bits are merely ones and zeros which are signaled by different
voltages etc in the line encoding.

Bits do not occupy line space.

Measurements of how fast data can be moved over a wire are the time it takes
for a signal at one end to be heard at the other.   The amount of data
(signals) which can be moved across a wire is ascertained by the line
encoding method, and how many signals the encoding system can be made to
produce in a second.  Minus the delay factors between point A and B of
course.

I seem to recall reading some papers from folks at the US Berkley computer
science dept a few years back that researched the various line encoding
techniques etc that were quite interesting.  I cannot find them now that I
need them though!!

BTW, my calculations for the speed of light resulted in 299,793,100 m/s

Re: Napster Question

[whatshakin]

The easiest way to circumvent the whole napster problem is to put into
effect a security policy that states that anyone caught downloading .mp3's
and anything else similar in function will be held accountable with their
jobs etc.   Just make sure you get the backing of the big-wigs before you go
yelling.

Re: TACACS+ and RADIUS

[whatshakin]

Along with what this member said, the TACACS+ philosophy is 'security at any
cost'.  RADIUS is more along the lines of 'good security but good
useability' too.   You will find TACACS+ has a more granular approach
overall and a significant enhancement to Cisco products in general.
Conversely, RADIUS will be generally easier to etc.

Re: Learning PIX??

[whatshakin]

The great thing about Cisco hardware is it retains its value quite well.
With that in mind I would suggest buying a used one from Ebay.  Play with it
until you are satisfied and then resell it at very close to (or the same as)
what you paid for it, essentially costing you little or nothing to get PIX

What is kind of odd here though is you would expect response times to be
almost identical if they are pinging from the same interfaces to the same
destination, and using the same size packets.

3600 module NM-1FE1R2W

[whatshakin]

I have a Cisco 3600  NM-1FE1R2W module I would 
like to get working in my 2621 if possible.  However, all the docs I have 
found on this module indicate it is only compatible with the 3600 series 
routers.  I plugged it into the 2621 for the heck of it and it powers up OK 
(LED's) but the IOS does not see it.
 
Has anyone gotten one of these to work in a 26XX 
router and if so, what was the trick please?
 
Cheers

Re: Configuration Comparison

[whatshakin]

I believe 'windiff' from the Microsoft NT 4 
resource kit is one. 
 
Pretty much all flavors of unix can handle 
this with built in commands but I cannot remember any of them right now. :-(

Re: Help with Cisco 2621 please

[whatshakin]

Hey Folks,
A big thank you for those of you that responded to my call for help. You got
me thinking, and I eventually solved my problem.  Here are the events which
caused my problem and the steps I used to rectify it, for those of you that
may run into this in the future.

I downloaded a 11.3 version of IP Plus IPsec 56 IOS to the router testing
versions which would offer me the ability to configure ISL encapsulation
(VLAN routing) via subinterfaces on the Fast Ethernet ports on the 2621.
After the initial download it worked fine.  However, after the first reboot
I found I could no longer see the two 10/100 interfaces any longer

ie: sh int
router>

I erased the flash and NVram to rebuild from scratch (stupid).  After
erasing and reloading, the router booted into rommon. From rommon I used the
following commands to tftp the old image back into flash:

rommon 1 > tftpdnld

rommon 2 > IP_ADDRESS=148.1.1.13
rommon 3 > IP_SUBNET_MASK=255.255.255.0
rommon 4 > DEFAULT_GATEWAY=255.255.255.255
rommon 5 > TFTP_SERVER=148.1.1.2
rommon 6 > TFTP_FILE=c2600-i-mz.120-3.T3

rommon 7 > tftpdnld -r

Image was succesfully downloaded

rommon 8 > boot flash

Image booted and I was back into a working 2621.  Reset the configuration
register to 0x102 and did a 'copy run start' to put the router back into its
original state.


Good learning experience. However, I am still back at my original problem of
trying to find an image that will do the ISL encapsulation on the fast
ethernet ports so I can practice some VLAN routing.  The 12.1 versions of
IOS above the IP feature set require 16 flash and 40 dram, I only have 8 and
32 respectively. If anyone knows of a 12.0 version that can utilize ISL I
would appreciate you passing the image name and feature set along.
A cheap supply of 26XX memory might suffice too :-)

Cheers.

Re: Portfast ???

[whatshakin]

I see no reason you cannot bring up both switches at the same time. Once the
2924C has been up for a minute or so you can start pulling the patch cables
from the old switch and start putting them in the new one.  Your switch over
time will be essentially painless as long as the new switch is configured
correctly.

Command history on a Catalyst 2901 Non-XL

[whatshakin]

Is there a command I can use to make a Catalyst 
2901 (non XL) show me my previously entered commands by using keystrokes like 
the up arrow (VT-100) etc.  I would rather not have to type 'his' end enter 
!#of command I wish if possible.  I hazzard a guess this is the same 
as a Cat 5K command for those of you that may be more familiar with that 
model.
 
Thanks a lot.

Re: ISL on sub-if

[whatshakin]

I just tried 12.0.3T3 Enterprise Plus and 12.0.4T 
IP Plus on a 2621 and neither version has an encapsulation command available 
under the interface config mode.  Both of these run on 8 flash and 32 
Dram.  I finally found it on a 11.3 IP Plus IPSec 56 image which also 
requires 8 flash and 32 Dram.  I looked 
on the IOS software upgrade planner, the Software Compatibility Matrix and 
various IOS release notes looking for a feature set that is not so difficult to 
get (expensive) but none of them gave me any specifics to work with.  I am 
going to check the 12.0.4T version of IP Plus IPSec 56 ( 8flash/32dram) tomorrow 
just for the hell of it, and see whether that image has it (almost 
guaranteed).  I will post the results.

Re: ip classless ?

[whatshakin]

This is wrong amigo.

The 'ip classless' command is used when configuring default routes.  It is
used because when you create a default route on a router it gets advertised
as 0.0.0.0 in addition to the default network.   When a router recieves the
advertised default route it will forward packets to a destination which does
not appear in its routing table.  Specifically you need to use the 'ip
classless' command when using IGRP and EIGRP because they only advertise the
network you configured on them.  If you do not use this command to enable
the default path to be used for non-connected subnets of the same major
classful network, the packets will be dropped at the router.

Re: Using Queing over the Internet

[whatshakin]

If you are limited to one ISP anyway, you can already do your own tunneling
using IPSec etc without needing to employ the services of an additional
third party.

Re: Transit traffic

[whatshakin]

That doesn't make a lot of sense Ed.  Transit traffic is that which is
addresses outside your AS.  This means everyone using BGP with more than one
AS generates transit traffic.  Transit traffic then cannot be 'sub-optimal'.
If an ISP had a geographically dispersed network, they would have to move
traffic within their own network via transit traffic unless they used one AS
for all locations.  Doing this over public or leased lines would probably
not be a good idea.

NTP synchronization

[whatshakin]

Is there a command to force time synchronization 
?
 
Cheers

RSH command help please

[whatshakin]

Hey folks,I am going through the rsh commands 
on a 25xx router trying to figure out how I can get it to work with my NT server command prompt. I have been unable to get this 
to work thus far using numerous permutations and 
do not know why. Please look at the commands I used below and see if I have 
forgotten anything or if I misunderstand the 
usage parameters etc.
 
Feedback appreciated.
 
My router commands:
 
routerb(config)#ip rcmd 
rcp-enablerouterb(config)#ip rcmd rsh-enablerouterb(config)#username 
administrator nopasswordrouterb(config)#ip rcmd remote-host administrator 
148.1.1.2 administrator enable routerb(config)#ip rcmd remote-user 
routerb
 
The relevant info:
 
*Routerb eth 0 IP: 148.1.1.4  Can ping it from 
NT box.*Logging in under NT with username administrator*IP of NT box 
148.1.1.2*Using command on NT box: rsh 148.1.1.4 -l administrator -n sho

Using the debug ip tcp rcmd the output is as 
follows:

Re: IPX routing question.

[whatshakin]

I guess your problem is that now the computers on one network cannot see
those on opposite network right?  Anyhow, Novell 3.X and 4.X require the
same identical EXTERNAL network numbers.  By the looks of what you have
given us you need to revert the 887 network back to 888.  Make sure your
frame type is consistent across the network too.

Changing hardware should not make any difference.  Perhaps someone with
first hand experience can confirm this.

Do some double checking on the modems to make sure they are working
correctly.

HTH

Let us know how you fare.

Re: Follies Answers

Good job Chuck.  This is exactly what we all need to keep things fresh.

Tell me, what functionality does one need to implement that kind of
lock-down control of a Cisco router? Are you using some kind of RADUIS or
TACACS+ software or the built in features of the 12.X IOS ?

Keep up the good work.

Re: Working hour

[whatshakin]

Working only 40 hours is not lazy!  In fact if you are forced to work more
than 40 hours you are probably working for an outfit that is too cheap to
buy the full array of resources you need or they are understaffed.  Either
way you probably don't want to be working for that kind of a show.  There
are of course times when a business' hours need to be accomodated but they
should be few and far between and not difficult or time consuming because
you will have time to plan your procedures.

Maintenence of a network does not and should not require any overtime,
changes should be well planned and thoroughly investigated to avoid
interruptions, and as such, with a good contingent backout plan, usually be
able to be implemented during normal hours...emergencies not included.
Initial rollout/upgrades may require some extra curricular hours but this
would only be in the event of having to reuse some of the existing
equipment, which is unusual because generally the reason you are there is to
replace old underpowered equipment with better stuff.  In the event you are
rolling out all new equipment, there is no reason you cannot build and test
your new network thoroughly before switching over to it. The switch over
however, often requires a weekend.  ISP's often require 24/7/365 uptime but
they should generally have enough redundancy to allow you adequate time to
make your changes.

The most common reason for working overtime is because of impromptu changes
which need to be made or an emergency has arisen which cannot wait for
planning.  Good planning and design should minimalize the former.
Unfortuanately, the nature of the beast means there will always be the
latter, but even those can have minimal impact with good planning and
monitoring practices in place.

Bottom line: 40 hours weeks are normal. Rotating the staff roster, two or
three additional weekends a year should be max.

You never mentioned the amount of memory in your routers.  Also, which book

Re: Dealing with the garbage mail...

[whatshakin]

I am feeling like ripe idiot at this time :-0  
When I posted the original message I posted it to the wrong group!  It was 
intended for the comp.dcom.sys.cisco mob.
 
1000 apologies. I have been working on some 
labs for the last couple of hours and did not notice I seem to have started a 
little something here.
 
That said, it wouldn't do any harm to do something 
about the 25% of duplicate garbage that hits this list 
either.

Re: Boot ROM upgrade

Boot roms are free from Cisco.  All you need to do is call and ask for them.
They will charge you for shipping only.  The number to call is 800-553-6387.

Re: Masters degrees / distance learning

[whatshakin]

I'd like to interject a little if I may.  Having all cert related
credentials will certainly open the doors to decent money and better and
better opportunities in the IT related field.  All certs and no degree
however, (in most cases) is probably going to limit one's potential for
growth opportunities.  To expound on his further, having a degree and
numerous certifications in the same discipline (IT in this case) could also
hamper ones long term potential growth opportunities!  I am referring to the
possibility of moving into management positions in this case.  Here the lack
of business related skills could draw many obstacles to which overcoming
them may prove difficult.  It seems logical that a combination of both
technical and business skills/certs will provide one with the best platform
onto which you could build a solid career.  Unfortunately, with bachelor
degree's becoming almost a commodity these days, you may soon need to set
yourself above the crowd with a graduate degree and high level certs of
sorts.  I dare say the folks with a MBA and CCIE will soon find themselves
running the businesses of tomorrow.

Re: Please tell me...

[whatshakin]

I think I can speak for a large percentage of us that frequent this
newsgroup.  We are tired of reading the same old wasteful posts day in and
day out.   All these questions have already been answered in may places.
Firstly, all those seeking any Cisco certification will own various study
guides, these pretty much have the answers to any cert related stuff you
need to know.   Secondly, the Cisco website has the answers to anything you
might want to ask, and lastly, the newsgroup alt.certification.cisco was
setup for this very reason .  What is the real bummer though is the fact
that people don't even bother to look back in the archives, you can find
these answers about a thousand times!

Post upgrade question...revised

[whatshakin]

Hello folks,
I just did an IOS upgrade on a 25xx series router 
and after it completed successfully I get this message on the console.  It 
looks like the IOS is looking for a configuration file of sorts and cannot find 
it.  Please explain what it is looking for, and how to make it 
stop.
 
Loading network-confg ... [timed out] 
   
Loading cisconet.cfg ... [timed out]
 
Loading 2520t-confg ... [timed out]
 
Loading 2520t.cfg ... [timed 
out]  

TIA

Pre upgrade question

[whatshakin]

Hello folks,
Whilst attempting an IOS upgrade on a 25xx router I 
inadvertantly fatfingered the file name of the file I was downloading.  
This caused the tftp process to go into timeout mode of sorts.  The message 
relayed was something to the effect of 'waiting 120 secs for retry' then 
'waiting 240 secs for retry'.  I could not escape out of the process using 
the usual break and escape sequences.  Please tell me the escape sequence 
so I don't have to wait 360 seconds for the process to stop itself again should 
I ever do this again.
 
TIA
