Noob question about router IP on SDM Worksheet...

The SDM Worksheet says,
L6A
Router IP Address
Copy the subnet in field L1A to field L6A.
If L1A has subnet field of 192.168.10.0, then these instructions make the router address 192.168.10.0.
I thought the first IP on the subnet was the default IP for the router, eg 192.168.0.1

Chris
I am as baffled as you are looking at the link you provided. If you used the example they give then all interface IPs would end up being the subnet address which is clearly wrong and more importantly would not work.
In terms of the addressing to use it is common to allocate static IPs from the start of the subnet as you say, athough this is just convention ie. any IP from the subnet could be used.
So unless we are both missing something obvious i would just ignore what the sheet is saying and do as you suggest in terms of allocation.

2 noob questions about speaker settin

. What if I don't sync the Creative speaker settings with windows control panel speaker settings?
2. What if I the speaker settings(both Creative and windows) don't match my speaker type?For example, I have only headphone connected to my Audigy 2 ZS but I set the speaker setting to 5. or whatever else. Will this improve my sound quality in games such as Battlefield 2? Am I?supposed to get the virtual 5. surround sound effect? Because I've heard that cmss upmixes stereo sound in?games to virtual 5. or 7. surround sound for headphones.
Thanks.

Re: 2 noob questions about speaker settings?slightlys I have a slightly different set up.
I have 5. speakers that I use for movies and some games. For BF242 I use headphones because they give you an advantage as you can hear people creeping up behind. The virtual surround sound is really good with my XFi xtremeMusic.
First I don't think it matters what you select under Windows Control Panel as the Creative Console Launcher updates speaker settings in Windows. Second if you want virtual 3d with CMSS on headphones just select headphones and enable CMSS3D. Then click the 'headphone' button on the CMSS3D tab and you can test the sound - a helicopter pans around in 360 degrees.
Then in games set the software to output 5. - AFAIK. Battlefield seems to do this automatically but I can't speak for other games. I'm assuming the Audigy has the same CMSS3D tech that the XFi has.

Question about router WRT54 GL

Good afternoon, I have following problem/question about router: WRT54GL.
I configured the router to operate in my network without any problems except for the following:
When I made tests of speed on computer which is connected directly to the cable from my ISP (ethernet, speed 64 mbit /s during download). When I connected the cable from ISP to the router and router is connected to the PC also using ethernet(from router port 1 to the pc) the speed behind a router decreased to 20 mbit. What I am doing wrong? or is it just a limitation in router's performance?
Thanx for any help
Johny Krekan,

Open the setup page of the router.
Set the MTU to Manual and change the size to 1365.
Save the settings and power cycle the router. Check the speed.
Make sure that firmware on your router is latest.

Noob question about launching apps

Greetings all,
Just made the switch to a Powerbook with OS X Tiger, and have a question about launching applications; specifically how to do so without using the mouse. On my Linux boxes (one at home, one at work), I do most of my work from the keyboard, without resorting to the mouse, even in Gnome or KDE.
In Tiger, I can select applications on the desktop, but haven't been able to figure out how to launch them without "clicking"... I've Googled and searched these forums, but no luck so far. Under Linux, it's the Enter key. I assume in Tiger it's some key combination...
I know there's probably a simple answer, but I've not been able to happen upon the appropriate key combo it at random, so I thought I'd ask the experts.
Be gentle, I've only had my PB a week!

To help you in your quest to keep your hands on the keyboard you should check out apps like LaunchBar and Quick Silver. Your hands will never (well... rarely) leave the keyboard again.

Noob question about swicthing port on a router

I am trying to understanding vlan on switch and router with packet tracer 6.
I thought switching port on a router will act as it does on a switch (mine are 2960).
I use a router with 1 WAN port and 4 switching port to emulate my cisco 881 (without wireless). Everything was working good with my 5 switches and 4-5 VLAN..then doing a ping test between VLAN.. I discovered that PC belonging to differents vlan can ping each other on a router - switching port...then i remake a basic scenario and post it here. i probably missed a basis of vlan.
FA 0/0 (the WAN port) is not connected.
FA 0/0/0 are port switching on the rooter.
According to my image...why pc0 is able to ping pc1 as there is not a specific route between them on the rooter...May be it is the C on the left side meanig connected..thought we need a static route to make one network communicate with another if they are not on the same network.

The actual ports you connect the PCs to are L2 ports only ie they are not L3 so they cannot route. But you have also configured L3 SVIs (Switched Virtual Interfaces) on your router and it those that are doing the routing.
An SVI is a virtual L3 interface. So from your configuration where you do a "sh ip int" you can see at the bottom
vlan 10 192.168.0.1/24
vlan 99 192.168.99.1/24
those are your SVIs. If you also look at your routing table it shows entries for both your subnets as directly connected routes with those SVIs as well.
If you do a "sh run" you should see in your configuration something like this -
int vlan 10
ip address 192.168.0.1 255.255.255.0
int vlan 99
ip address 192.168.99.1 255.255.255.0
SVIs are generally seen on L3 switches and as as i say there are not configured on the actual port. The idea is a switch could have say 24 ports in vlan 10 and 24 ports in vlan 11 and then you simply configure SVIs for both vlans and now clients in each vlan can communicate with each other.
So to be precise SVIs are virtual L3 interfaces for a L2 vlan. They act much like physical L3 ports eg fa0/0 from your example ie. you can apply acls etc. to them but they do have differences.
Hope that makes sense.
Edit - to confirm all of the above you can simply remove or shut down one of the SVIs and the PCs should no longer be able to communicate.

Question about router

Hi,
I have an old route- A linksys 80211b. I have had it for probably about 4 years. I have 2 computers networked via hard wire and a wireless print server.
I often have a problem with my internet connection. I have a fast cable connection.
But I will go to safari and a page starts to load ans then stops in the middle. I then need to hit refresh a few times to get the page loaded. First I thought it was my computer, but realized that the it does this on both my macs. By the way it does not do it on my PC.
I went to compusa today and they suggested that I get a new router. they had me buy a dlink 108G mimo. They felt this would solve the problem,
I did not even open the box yet but wondering if everyone else out there agrees it is time to upgrade my router and this may be a soloution to the problem.
Part 2 of my question is will the dlink connect to my linksys 80211.g print server?
Any insight would be great.

I don't think it's the Router... might be of course, you could tell by hooking one computer directly to the Modem.
I think it might be the Modem...

Noob question about trying to duplicate rows in a table

Simplification of problem is I've got a table with user_id, name, year where user_id is pk. I would like to take all the rows that match year=2008 and insert them into the same table, but start the user_id at a certain number and set year=2009.
I know this doesn't work, but it's what I want to do in noob-code:
INSERT into TABLE (
user_id, name, year
) VALUES (
SELECT user_id_seq.nextval after starting at 3500, name, 2009 from same table doing insert to where year = 2008
I've contemplated using a temporary table, I've also seen mention of cursors, but don't quite understand what they are. I'm really, really new to Oracle and SQL in general, but am familiar with programming and shell scripts. I know more in depth searching might land me what I want, but I think my search syntax would be just as weak as my knowledge of the material. I'm just thinking this is something so basic and easy that my searches aren't using the right terms to catch a hit.

Hi,
Welcome to the forum!
You can INSERT all the results of a query by substituting the query where you otherwise would have "VALUES (list)".
For example:
INSERT into TABLE_X
       (user_id,              name, year)
SELECT user_id_seq.NEXTVAL, name, 2009
FROM    table_x
WHERE   year = 2008;This assumes that the sequence user_id_seq exists and is ready to issue the correct value. (It's unclear if that's part of the problem.)
Temporary tables and cursors (which are a way of getting query results in PL/SQL) are only useful for inserting in rare situations, where you have to do very odd, convoluted things. Think (at least) twice about how to do what you need to in SQL, and if you can't think of a way, then ask.
Yes, basic things often are hard to search for, especially if you don't know the right terms.
There are several good teach-yourself SQL books that explain this kind of thing. Getting one would be a good investment.
[All the Oracle manuals|http://www.oracle.com/pls/db111/portal.all_books] are on line. There's an example of this in the SQL Reference manual, under THE INSERT command.
Edited by: Frank Kulash on Nov 26, 2008 12:59 PM
Clarified usefulness of cursors. They have a lot of good, common functions, but helping with INSERTs is not one of them.

Noob question about Airport

I have one of the early G5 PowerMacs (single 1.6 gHz). It currently doesn't have an Airport card, but I'd like to install one or an equivalent. Here's my two questions:
1.) Are all G5s compatible with Airport Extreme cards?
2.) Are there good third party alternatives out there?
I wish Apple would be clearer about what systems are "Airport Extreme Ready".
Thanks in advance!

Noob question about HDR images

hi everybody! i am reading this book about photoshop hoping to understand a lot more than i already know about pixels and colors and image dinamics and such..i got to the chapter about HDR images and here's what i dont get. as i understand, given a HDR image it has 32 bit depth meaning its file contains much more information about contrast and brightness than any existing monitor can output, so when u open it in photoshop u will never see its true quality. my question is( and i admit it may seem pointless to some, but i am committed to understand the cause and purpose), when converting it to 8 or 16 bit depth this window pops up asking me to tweak gamma, exposure, shadows and highlights, etc., but why is this linked to the conversion process? why not simply convert it, maintain the same appearance as before and then if needed manually adjust using all the image controls from the photoshop menus? i have CS6, if that matters.

I don't know if this will help, but I've heard about HDR monitors (still very expensive), which supposedly very accurately display the HDR values. If you hang one on the wall in your house, people might think it's a window, since it is literally a source of light, in the same way a window to the outside world is.
Possibly the most surprising use of HDR imagery is in 3D apps where global illumination models are used. HDR imagery literally is the only source of light for these images. There are no lights in the scene, only HDR imagery. This is because of the great dynamic range of HDR.
A more practical (to me) use of HDR is when resurrecting antique images. If you scan multiple exposures from old prints, then create HDR, sculpting values in 16-bit becomes a very powerful tool, only due to the HDR value range.
Photoshop, although it can edit very well in 16-bit, can only show 8-bit representations of HDR imagery, since almost all monitors are 8-bits per channel. Because of the monitors, we can only see a small part of what is actually present in the HDR file.
I've never done it, but I imagine that if we all had HDR monitors, we'd need to wear protective glasses (like you wear driving in your car when the sun is out) most of the time to do our work. :+)

Naive question about router

Hi, all,
First, I'm definitely a beginer in network field, I don't know much about routers.
Recently, I got a CISCO2610XM router. I tried to use it to set up a LAN and connect the LAN to the network.
However, I found the router only have one FastEthernet0/0 port, and other two ports are console and aux (which I think are used to configure the router, am I right?).
Do I need extra network module (card) to connect to the LAN? And what card should I choose?
The figure I planed for my LAN is:
Network
|
|
ROUTER 2610XM
|
|
A Linux box (Squid, as a cache engine)
|
|
A Switch (NetGear GS105 Gigabit Switch)
|
|
several computers
Thanks in advance.

I did not realized you had in mind ISP , this changes things, but lets assume you'll have a static IP for ISP_INternet connection , I'll see if can get a chance to lab this out ,this is a quick setup but you still need to configure some security ACLs.
On 2610XM router:
ip routing
interface FastEthernet0/0
Description CONNECTION TO 2950_SW_PORT_24
no ip address
no ip proxy-arp
duplex full
speed 100
no shut

ip route 0.0.0.0 0.0.0.0 ISP_router_interface_IP_address
on the switch config something like this:
vlan database
vtp domain test_net
vtp mode transparent
vlan 2 name outside_ISP_Internet
vlan 3 name 192.168.2.0_subnet
vlan 4 name 192.168.3.0_subnet

switchport access vlan 4

etc..
interface fastethernet0/24

Physical would look something like this.

[Edit]
For the Squid server say you have a spare public IP of 2.2.2.2 and Squid local IP is 192.168.2.254 you can create a static NAT on 2610XM router as:
ip nat inside source static 192.168.2.254 2.2.2.2
in addition to access list to allow inbound access through public IP.

Question about router connections

Does a wireless router need to be connected to an external modem? My modem is essentially a card in a box on the outside of my house, so connecting to it, other than through a wall outlet, is pretty much out of the question.
My connection goes from wall outlet directly to the ethernet port on my pc...am I even able to connect a wireless router?

The wire that runs from your modem outside, to the outlet on your wall, apparently allows you to connect directly to your modem.
Probably you can simply run a wire from your wall outlet to a wireless router. However, before investing in a wireless router, I would suggest that you verify that this setup will work with your ISP (internet service provider). Also, check your ISP's web site. They have probably already posted directions on how to set up wireless with their system.

A noob question about precedence...

Ok, here's the question.
let's say:
int a=0;
a=a++;
when a is evaluated, 0 is returned.
isn's that expression like this?
a=a=0;
a=a+1;
apparently I'm wrong.
so if i forced a parentheses on it
a=(a++);
but again, a is evaluated as 0,
I know how ++a would work, but i'm really curious about the suffix one.
can any one explain to me?

i mean how no matter what u do to
a=a++
i know in this case that a is evaluated first b4 it is added to 1,
but it's gona add that 1 eventually right? so the evaluation of
a in the en should be 1.
Ah, I'm so confused, help

Noob question about DIV tags

Learning DW and CSS so patience is in order .
I've being reading numerous posts here and on the web about avoiding tables for laying out web pages. I can see the advantages in terms of cleaner codes and easiness of updating and changing sites at a later time. So I started learning about DIV tags (although tables is very easy for me) and have practice a few times with fairly good results, love the absolute positioning with it. Having said that, for the love of me, can't find a way of centering horizontally a page designed with DIV tags (due to ignorance), for example, 1 column/three rows page, after defining styles, size and colors I enclosed everything in another DIV tag, wrapper I think is called, but have not found a way of centering it on the page, text-aligment on the DIV tag only centers the text not the DIV itself, how to go about this? Help is appreciated.

love the absolute positioning with it.
Get over it. It's a trojan horse. Absolute positioning is not a general layout method.
To center ANY block (non-absolutely positioned) element, use CSS to give it a width and left/right margins of 'auto'. For example -
<div id="foo">...</div>
That div will be centered with this CSS -
#foo { width:300px; margin:0 auto; }
I think you are on the wrong path already, though. Stick with tables (which you say are very easy for you) UNTIL you a) understand CSS well enough to understand what absolute positioning is and why I say it's bad, and b) understand how to use float, margin, and padding to place things on the page. Then you are ready to move away from tables.

Ultra-noob question about creating clips

Sorry if this is answered elsewhere - I don't even know where to look.
I'm working on a simple editing project. I've sucked in (I forget the proper term) an entire DV tape of material into one big file. Now I'm trying to pick out the good shots and save them as separate clips - about 50 of them. These clips will then be converted to a different format and reassembled using some special software outside of FCE to create an interactive web video.
There seem to be about a gajillion ways of doing this. Master clips, independent clips, sub-clips. Right now I'm having a problem with clip names because of the master/associate business. I want to organize individual clips into folders (Folder A -> Clips A1, A2, A3, etc). But when I try to name a clip, ALL the names change. And no amount of setting the clip as Independent seems to affect it. Not only that, but I'm so green I still can't figure out what to highlight - the clip in the timeline or the clip in the folder or both.
Can someone point me in the right direction? I don't even know what to ask.

G'Day ap0110,
Welcome aboard the FCE forum.
Here is another method:
Double click the long clip in the Browser and it opens in the Viewer.
Mark an In and Out point in the Viewer. You will have two black triangles facing one-another in the Viewer scrubber bar when completed. Notice the bit in between the triangles is lighter in color than the rest. This bit can be made into a re-namable Sub-Clip.
Go to Modify> Make Subclip. Command-U (keyboard shortcut).
The modified clip now appears in the Browser ready to be re-named. Enter new name.
Do this as many times as required.
Right click in the Browser and a pop up appears with an option to create a _New Bin_.
Drag the newly named Sub Clips into a Bin of your choice.
