Cannot get the hosts file to operate or change.

I have tried to every way I could find on the internet to change the hosts file on my Mac OS X 10.4.11 computer plus several newer macs that operate in my office. I was able to easily do it on the PC's but not on the Macs. I modified the /etc hosts file directly to no avail, modified it using the terminal commands and also tried using the NetInfo manager. I am NOT a tech guy, just a guy trying to get his computers to work properly. A tech company just changed our router to a Cisco ASA device which is why this change needs to be made, they did not know how to make the changes to the hosts files on a Mac. Everybody in the office loves our Macs so to not be able to get to our own website and webmail is frustrating. Here is what I changed the hosts file to:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1 localhost
192.168.16.2 auctionbid.stoutauctions.com
192.168.16.3 mail.stoutauctions.com
192.168.16.3 smtp.stoutauctions.com
192.168.16.4 stoutauctions.com
255.255.255.255 broadcasthost
::1 localhost
Is something else in the system I need to change to make this take effect? Is something set wrong? Any help would be greatly appreciated.
Also if anyone knows of a reputable company that will do remote work on Macs, please let me know. I have a few things that I don't know how to do and would not be worth a trip to the middle of nowhere for a tech company so if they can do it remotely that would be great.
Thanks!
Greg

Hmmm, the line after...
127.0.0.1 localhost
Should be...
255.255.255.255 broadcasthost
Not sure if that is it or not.
Did you see this article, especially for adding from a hosts.txt file?

Did you flush the DNS Cache after changes?
How to Flush DNS in Mac OSX using Terminal...
In Mac OSX Leopard, you can use the command dnscacheutil -flushcache to flush the DNS resolver cache:
dnscacheutil -flushcache
In Mac OSX versions 10.5.1 and before, the command lookupd -flushcache performed the same task:
lookupd -flushcache

Recently purchased song and another I transfered into my ITunes library vannot be set up in a playlist.I get the message"file cannot be located".Originally I could listen to the purchased song but now that will no longer play.What do I need to do to ?

Recently purchased a song from ITunes and another that I downloaded from a CD will not transfer to a playlist and will not even allow me to listen to the songs.I get the message "file cannot be located"What can I do to get my system to locate the file?Originally I could play the songs from my desktop and I was able to transfer to my IPad.

Because the location for each song in your library is on your hard drive. If the hard drive isn't there, how can iTunes play it?
You'll have to move/copy the music from your hard drive to your computer's hard drive.
Basically, EASIEST way to do all this, if you don't care about your play counts, etc...
-Delete EVERYTHING from iTunes, so that your library is now empty.
-Go to "Advanced" inside of the "Preferences" window, found in the "Edit" drop-down. You can also access Preferences by pressing Ctrl+, (Press Ctrl and the comma key)
-Change your iTunes Media Folder Location to something simple, but on your computer. I use C:/iTunes. Make sure "Keep iTunes Media Folder Organized" and "Copy files to...." are both checked. You can close Preferences now.
-Now, drag and drop your music from your hard drive into your iTunes library. iTunes will automatically add the music to your library, as you would expect, and also creates a copy of each file to place into that iTunes Media Folder you just created.
Shouldn't have any more problems...

Did you download the Basic/Free version?
I also thought the Trial period was as long as you needed!?
What is your Warranty and Return Policy?
You get to use VueScan for as long as you want before you buy it, so we recommend you test it before you buy it to make sure it meets your needs.
All sales are final and there are no refunds.
Isn't this a bit harsh? Naah I actually prefer to solve problems, and if I offer refunds, people give up too easily. If I can't solve your problem after you send a few Problem Reports (see above), I'm happy to give a refund.

HT201210 I have done all of the things on this list, to include editing the hosts file with no the same error each time (3194). I am trying to restore my iphone 4 ios 6 to get it unlocked. Diagnostics show no issue communicating with apple. Help.

I am trying to restore my iphone 4 ios 6 to acheive unlock. hit restore and it unloads software, confirms with apple then displays the 3194 error. I have turned off my virus scanner, unplugged all usb except for iphone, edited the hosts file and run diagnostics which showes communication with apple is fine. What do I need to do to get my ipone to restore?

There is nothing wrong with the OS update.
Delete ALL your email accounts.
Restart Playbook
Put the accounts back and ensure they are all set with PUSH ON. Manual (push off) will burn battery.
Similarly delete your wifi connections and add back when required.
Turn off wifi is not connected to wifi.
Any "hunting for connection" in email or wifi will burn up battery.

I have an iphone 3 that was synced awhile back.All was fine,now I need space on the phone & cannot get a picture file with 344 photos off the phone. I've tried not checking any folders to sync

Email it to yourself, then save the file and then see if you can convert it to MP3.

That is usually caused by a missing unpack directive (<em:unpack>true</em:unpack>) in the file install.rdf of that extension.

Firefox cannot modify the needed file. I get this message when I try to add a theme. I am using Linux Mint 14.

I am currently using Linux Mint 14 with Firefox 21. I am trying to add new themes and add ons, but I keep getting the message "firefox cannot modify the needed file in linux". How can I correct this?
Thanks

Click the Firefox button at the top left, then click the ''Help'' menu and select ''Troubleshooting Information'' from the submenu. If you don't have a Firefox button, click the Help menu at the top and select ''Troubleshooting Information'' from the menu. Go to Open Profile Directory (or something similar) and delete a file named user.js

MPEG means a whole bunch of different formats. What are the exact specs of your media? MPEG files often have multiplexed audio. You will probaby have to convert this.

I cannot get the file "Photoshop_13_LS16.7z" for Photoshop CS6, Photoshop CS6 Extended English to download; the url goes to an ascii file on screen.

I cannot get the file "Photoshop_13_LS16.7z" for Photoshop CS6, Photoshop CS6 Extended English to download; the url goes to an ascii file on screen. It's at Download CS6 products. Can you help?

use a different browser.
you can also try dl'g from prodesigntools.com
if you follow all 7 steps you can directly download a trial here: Download CS6 products
and activate with your serial number.
if you have a problem starting the download, you didn't follow all 7 steps, or your browser does not accept cookies.
the most common problem is caused by failing to meticulously follow steps 1,2 and/or 3 (which adds a cookie to your system enabling you to download the correct version from adobe.com).
failure to obtain that cookie results in an error page being displayed after clicking a link on prodesigntools.com or initiates the download of an incorrect (eg, current) version.

I have imported a jpeg photo into iPhoto and cannot get the Places map to let me fix a position on the map. It remains disabled for my photo. Checking out the Help file has not given any solution.

I have imported a jpeg photo into iPhoto and cannot get the Places map tp show. I have tried the Help file and the information was not helpful. Can anyone give advice here?

I am using iPhoto 9.1.1. When I select thephoto, then Places I get the window (Places to lookup disabled). When I hit theInfo button I get the size an JPEG notification, and Faces and Key words. The “reverse” of thepicture shows a window with Rotate, Hide, Trash etc.
When I select Places, get the Google worldmap, and this case a pin on Sydney Australia showing that eighteen photos arecorrectly placed. I am unable to make the connection to San Francisco wherethis particular photo was taken on a very modern camera.

I have requested and accepted the most current Firefox program updates with my windows vista system. They are not registering but I am told they are downloaded. Then I cannot get the printer option to work with any version of firefox. in English

I have taken the firefox updates when offered to 4.4. I have the browser as an aside to Internet Explorer 9 as a backup browser. When I use Firefox I am being told my system is not up to date and I need a newer version. I download the version and keep getting told I am not current with firefox. When Firefox DOES work I cannot get any printer icon or settings to enable and allow the printing of a page. I have to use IE9 to get the printer to work. Using eBay I cannot get the uploading of pictures from my computer to consistently operate even though I use small JPG files under 500KB.

There are a lot of IntelliTXT like ''ad'' pop-ups possible.
If your current Adblock Plus filter settings aren't blocking some pop-ups then it is best to take this to the Adblock Plus forum.

I get the error: Cannot Copy 08 the curse in on my house: Cannot find the specified file. Make sure you specify the correct path and file name.
The song "the curse in on..." is on the "into the woods" soundtrack. I deleted the entire soundtrack from my iTunes Library, shut down and tried again. Same error. I did a search of all three hd (2 external and c) nothing found. I searched for song name and "into the woods" I even searched for the artist "Nicholas Parson Company" nothing on any of the 3 HDs. I also went into explorer and manually searched for the song under soundtracks, misc, various and I could not find it. I consolidated my library and restarted. I tried again and same error message. Can a level 4 or 5 offer any help. I am at a loss...
The error won't let me copy one library to another HD.

NullPointerException - Cannot get the value from variable f_cashGiven

In SubCheckout.java (a POS), what I want is when Payment button (f_cashPayment) is pressed, the action "Cash" is performed, get the value from Cash Given (f_cashGiven), do the subtraction and post the value as Cash Return (f_cashReturn). The code is filled in actionPerformed. But I cannot get the value by using f_cashGiven.getValue() from VNumber class. It returns NULL. This should be quite straight forward, but I do not know what is wrong. Please help!

If getValue() returns null, you need to trace the execution of the code and figure out which sequence of code is leading to the return of null. This method looks complex - a lot of if statements. If you do not have a debugger, put System.out.println statements inside the method to figure out what's going on.
