PIX commands- add ports [7:60976]

2003-01-13 Thread John Chang
I want to create an object-group but I'm not sure which one to use and how 
to use it.  I want to add a range of tcp ports and a few udp ports.  How 
can I do it? Thank you.

Which PIX to buy [7:52572]

2002-09-02 Thread John Chang

I'm wondering which PIX I need.  I need something that will work with OC12 
155Mbps when saturated.  Right now we have a T3 line and will eventually 
get an OC3.  I would need redundant PIXs.  Can anyone recommend a company 
that leases them?



Thank you.

Windows NT 4.0 and VPN client 3.6 Rel.K9 w/PIX 525 [7:51473]

2002-08-15 Thread John Chang

I have a PIX 535.  The server in the inside is a Windows NT 4.0 w/ the 
latest service pack.  From the outside when we use the Cisco VPN client 3.6 
rel. k9 on a win2k professional and try to connect to the NT server it 
doesn't connect.  I can however connect to any win2k workstation or 
server.  I must have configured the PIX wrong.  Any hints?  Thanks.

Switch plan [7:51476]

2002-08-15 Thread John Chang

How can I get 2 small switches 2500XL or 3500XL to be redundant.  The 
router has one 100 ethernet port?  Is it typical to use just one 100 port 
or is it better to have either 2 100 or 2 1000 ethernet?

Will this work or do I need 2 ethernet ports on the router?

On the win2k computers I was planning on putting in 2 nics connecting each 
nic into each switch.  Can both nics have the same IP address?  Thank you.

Re: Cisco PIX Novell [7:51303]

2002-08-14 Thread John Chang

Here it is.

We have a Cisco PIX 525.  The Novell 4.83 user/client is behind the 
firewall.  The Novell Netware 5.1 server is outside the firewall.  What do 
I need to do to make the client be able to sign into the server?  We have 
it configured so that anyone in the inside can do any ip to the 
outside?  The Netware client is set to use IP as the preferred method.

Looking at the syslog what happens is the client connects to the directory 
agent server which directs another server to communicate with the 
client.  Is there a way of telling the client to authenticate to a specific 
server.

Thank you.

  What version of Netware are you running on the server? If it 5
  or 6, it's
  native IP, so basically you're sending IP traffic out of the
  Pix, which
  should work. It sound as if your problem may be with the packet
  actually
  coming back into the Pix. Do you have any rules that may be
  preventing the
  server from responding back to the client? Here is the
  information from
  Novell's website listing the port that Novell uses
 
  TCP and UDP are both used by NetWare 5.1 and NetWare 6.0 for
  Pure IP
  connectivity. The following ports are used for communication.
 
  TCP 524 - NCP Requests - Source port will be a high port
  (1024-65535)
  UDP 524 - NCP for time synchronization - Source port will be a
  high port
  UDP 123 - NTP for time synchronization - Source port will be
  the same
  UDP 427 - SLP Requests - Source port will be the same (427)
  TCP 427 - SLP Requests - Source port will be the same (427)
  TCP 2302 - CMD - Source port will be a high port
  UDP 2645 - CMD - Source port will be the same (2645)

I thought I would add to this the decoding of the acronyms:

NCP sort of obviously NetWare Core Protocol, the classic client/server
protocol that Novell has used for almost 20 years.

SLP is for Service Location Protocol, a protocol for finding services that
may catch on, although admittedly it is mostly Novell and Apple making a big
deal of it. RFC 2608 defines the current version of SLP, version 2. I think
I read somewhere that Novell uses the older version. It's defined int RFC
2165. They use different multicast addresses which could be an issue.

CMD is the Novell Compatibility Mode Protocol. I knew it used UDP port 2645.
I hadn't heard of it using TCP port 2302.

Note that all of these ports might not be necessary for every
implementation.

The original poster needs to tell us what his problem is, if anything. Maybe
he was just getting info.

   Usually people set up a web interfaces for this. I don't
  really know the
   Novell Junk, but I would start by upgrading the client to
  Novell 6, if
   you even want to attempt VPN, if that's what you are trying
  to do.
  
   If the server is on the DMZ, you want cut though proxy
  (probably doesn't
   work with Novell). If you server is on the internet, you
  don't want to
   transmit your passwords over the internet in clear text so
  you need VPN.
  
   Save yourself a lot of headaches and trouble and switch to
  Microsoft or
   Unix.

call system routing [7:48358]

2002-07-08 Thread John Chang

I know this isn't cisco stuff but thought someone here could help.

Is there a way to have one 800 line and have it switched over to say any 
one of 10 or fifteen users?  And if another call comes through routed to 
another person.  Is this possible?  Or would I need say 10-15 lines?  The 
other dilemma is being able to change the extension so that if someone 
leaves we want to stop using that extension so that the person calling will 
get a message saying the user has left or it just hangs up.  I am looking 
for something easy to change the extensions since we have a lot of turn-over.

If there is another site/website/listserv that would help please direct 
me.  Thank you

John

  Can you use CW2k to do a search on multiple switches for a specific MAC
  address so that I can find out which switch and port the MAC address is
  from?  Or do you know what will do it?  It's a pain to look at multiple
  switches to find the MAC address. Thanks.

Switches/cables [7:3673]

2001-05-08 Thread John Chang

I looked at my G4 mac and the Apple System Profiler says 100Mbps/full 
duplex.  The 3548 XL switch says 100Mbps/full duplex.  How could that be 
possible when the patch panel connectors are 10Mbps and the connector on 
the wall is 10Mbps.  The cable is Cat 5.  I thought everything was suppose 
to be 100Mbps for the switch and the computer to register it as 
100Mbps/full??  So, what gives?  Thanks.

MAC address to port tool [7:221]

2001-04-11 Thread John Chang

We have 11 3500 XL series switches.  10 are connected to 1 switch.  There 
is only 1 VLAN.

Basic diagram:
switches
| | | | |
 | Switch
| | | | |
switches

Is there a tool out there that will easily tell me which port a particular 
MAC address is connected to at any given time?  Preferable something I can 
do a simple search for the MAC address and it will show me the port.

The problem I'm having is that we have a DHCP server and I hate all these 
BAD_ADDRESS.  When I ping the IP address it is live so someone is manually 
entering the IP address.  I don't want to go through all the switches to 
find the MAC address since it will be too time consuming.

Thanks.

Mzmaker

2001-04-08 Thread John Chang

I have a 2514 w/ 8Mb flash.  When I used mzmaker to compress IOS 12 that is 
10MB it worked fine.  However, after writing the .mz file to flash and 
starting up the router it keeps looping "Error : memory requirements exceed 
available memory
Memory required : 0x00AF99A0

Exception: Software forced crash at 0x111E (PC)"

and giving this error.  Does this not work since on a 2500 series router 
the IOS runs in the flash and not ram?  Thanks.

No. If you only fill the first bank that's OK.  If you fill both then they 
need to match.

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/cis2500/2500cfig/dualflsh/58674.htm

 From website above:

"Step 5 Insert the new Flash memory SIMM by sliding the end with the metal 
fingers into the appropriate SIMM connector socket (CODE 0 or CODE 1) at
approximately a 45-degree angle to the system card. If you are installing 
only one SIMM, install it in the socket labelled CODE0. Gently rock the 
SIMM back
into place until the latch on either side snaps into place. Do not use 
excessive force because the connector could break. "

RE: 2500 Flash ?

2001-03-27 Thread John Chang

Apparently I can't read.  Read his question wrong.  You are right 
Zorro.  Not the same as my problem.

This is what I have done:

1) Upgraded ROM chips to the newest XB2
2) Tried the Flash in another 2500 series router and shows as 8MB
3) When I put it back into 2504 it shows it as 4MB.

Are there any jumpers or something I'm missing? I have only installed one 
8MB Flash. Leaving one empty.  If I install 2 8MB flash it shows as 2 4MB 
flash SIMMs.  Thank you.

Firewall

2001-03-19 Thread John Chang

OK, maybe I should clarify.

We are in 1 building with  7 departments.  Only 1 department is going to be 
using private addresses.  We have a bunch of 3500 series switches connected 
to a router, yes we are switched to the desktop.  So I need NAT to 
translate so the 1 dept. can do netscape, email, and such in the 
outside.  The outside world can't see my internal network for the 1 
department, so do  I need a firewall from the outside since they can't 
connect using a routeable IP address?  I know if they came into the 
building then they could connect.  The other thing is I want home users to 
be able to connect to the file server using tunneling. Home users may or 
may not have private addresses, it depends on if they are on DSL, ISDN, or 
dialup.  Budget would be about $5,000 max. but give or take.  I don't want 
this to affect any other departments.  I'd prefer hardware but if software 
will do it that's fine too.  Will there be a noticeable difference if using 
software vs. hardware for 40 users? One other thing.  They will be using 
netscape for both internal and external.  The department is on multiple 
switches mixed with other departments.  What's the best way to implement 
it?  Thanks.

Portfast

2001-03-01 Thread John Chang

In the below website it says not to have portfast on if you connect 
switches, hubs, or routers.  I understand that point but what if a user 
connected a mini-hub (Ex. Linksys EtherFast 8-Port 10/100 Desktop Hub) 
or  unmanaged mini-switch (Ex. Farallon NetLINE 10/100 switch) so that he 
could connect multiple computers.  Would this cause any problems?  Thank you!


http://www-1.cisco.com/warp/public/473/12.html

Note: The portfast feature should never be used on switch ports that 
connect to other switches, hubs, or routers. These connections may cause 
physical loops
and it is very important that spanning tree go through the full 
initialization procedure in these situations. A spanning tree loop can 
bring your network down. If portfast
is turned on for a port that is part of a physical loop, it can cause a 
window of time where packets could possibly be continuously forwarded (and 
even multiply) in
such a way that the network cannot recover.

 Bob,
Howard answered this question for me a while back so I'll try to answer
 it
 for you now. This question is probobaly more in depth than you realize, but
 the question comes down to why did they used to say the equation for
 finding
 the amount of valid subnets is 2^#of hosts -2? And why now do we not -2?
 Well the short answer is -we used to use Classfull addressing. With
 classfull the reason we used the -2 was because it was a bad idea to use
 the
 all 0's or all 1's subnets(highly discouraged is I believe the
 terminology)When an all 0's subnet update was sent to a classfull router it
 would not be able to decipher it from the entire network. This is because
 in
 clasfull the masks aren't sent with the updates therefore when the
 classfull
 mask is placed on say 192.168.0.0/28 it would change it to /24 because
 again
 the mask wasn't sent. Which would end up causing some issues obviously. The
 other one was the all 1's subnets. I'll just make an example. If you think
 along the same lines as the all 0's. Again in a classfull environment a
 broadcast for a particular subnet would be interpreted as a broadcast for
 the entire network. 192.168.0.255/28 has different meaning than
 192.168.0.255/24.
 3Coms website has the best explaination I have found The article is called:
 Understanding IP addressing: Everything You Ever Wanted To Know by Chuck
 Semeria.
 Cisco, Microsoft, and the RFC's seem to dance around the topic.

  Yarrggh!
  Of course, that's
  
  (2^n)   (*not*   2^(n-1) )
  
  Maybe there *is* something to that aspartame story ;)

  Subject: CCNA 2 and subnets
  
  
  Sorry for the lame question, but I gotta know :|
  
  We know that subnet -1 (all ones) is valid to config in IOS and that 0
  is OK with
  
   ip subnet-zero.
  
  For purposes of CCNA 2, do we assume that subnet 0 and -1 are valid,
  vs. CCNA 1 (where they were not) for questions like,
  "How many subnets can we have with this mask?
  "
  ?
  Does the test make it clear in preliminary text?
  
  The archives seem to have conflicting answers.
  
  The Cisco Press ICND book (McQuerry, 1-57870-111-2) doesn't address the
  issue head on, but simply shows tables with (2^(n-1))-2 subnets.
  
  The Cisco Press 640-507 Cert Guide (Odom, 0-7357-0971-8) clearly says
  that 2^(n-1) is correct and yet points out that 0 is only valid with
  "ip subnet-zero" !
  
  Does anyone know the *definitive* answer for CCNA 2.0 ?

RE: VLAN

2001-01-15 Thread John Chang

I have a cat3500XL 12.0(5)XU.  Whan I do a sh mac. it shows destination 
address: varies mac addresses, address type: dynamic, vlan: 1, destination 
port: FastEthernet0/24.  So how can I find out the physical port the mac 
address is coming from?  Thanks.

CCDP

2001-01-04 Thread John Chang

What is the order you should take the exams to get the CCDP?  Should I 
follow cisco's flow chart or do you think there is a better way?  For 
instance can I take the CID first.  Thanks.
