Newbie Q about terminal and telnet

Not sure this is the right forum but I posted on the osx server threads with no reply so here goes.
Q. turning off the wan side telnet port on my router using telnet via the terminal.?
I've seen instructions some where about how to use telnet to turn off sip in a router re getting ichat to work. Can I close or stealth my telnet port in a similar way. also ping and ftp and 80 are open not stealth. (re shields up site.)
I'm used to seeing no real traffic over my old & possibly dead router unless I initiate it. I've just got the echolife hg520s over which their is continual if minor traffic and it bugs me.
Btw... in the firmwares http gui I've disabled the cwmp option and selected all wan side options as disabled including ping and telnet.??
Thanks

This is very strange. Being the paranoid kind of guy that I am, whenever I go on business travel, I run nmap against my home network (I'd do it more frequently from the office, but my employer's IT Secret Police blocks almost all outgoing destination ports), and this last trip (last week) I found telnet 23, http 80, LM Social Server 1111 (what the heck is that?) and 52869 open. In Terminal, I typed telnet {myHomeDomainName} and got a login prompt to my modem! Previous nmap about one month prior all was ok. I freaked out.
Once back home, I could not close the ports, even though the modem's configuration page said that the only port forwarded was my ssh port (as desired) and that remote management was disabled. I hard reset the router, I reinstalled the firmware from the critical recovery disk image, and I reinstalled the firmware update -- multiple times. That would close 'em off, for about an hour or two. I was on the phone with my ISP (Qwest) about three or more times for about 45 mins per call, and then, mysteriously, the ports have closed with no interaction on my part and have remained closed thus far for two days now. (It just so happens we have a WAP at work for visitors, puts 'em outside our really restrictive firewall, but when there, you can't access anything inside the corporate LAN when you do that, but I affiliated to that WAP anyways so I could run nmap this afternoon during lunch.) So I'm wondering whether my ISP's Secret Police have a backdoor programmed into their firmware set for the DSL modems that they sell, but they shut it down (at least temporarily) since I caught 'em, well, caught somebody, with my ports open?
Check your firewall logs for unusual activity: in Terminal, as admin-privileged user, type
+sudo cat /var/log/ipfw.log+
if unusual probes or activity, get on the phone with your ISP, ask why your modem config pages say your firewall is on and no ports are forwrded but telnet's open, and if you have unusual acitivity in those logs, ask 'em to start an investigation.

Newbie question about entity and view objects

Hi everyone,
My first ADF application in JDeveloper is off to a difficult start. Having come from a forms background, I know that it is necessary avoid using post-query type lookups in order to have full filtering using F11/Ctrl+F11. This means creating an CRUDable view and getting as much of the lookup data as possible into the view without losing the ability to modify the data. In JDeveloper, I do not know how to build my data model to support that. My thought was to start with a robust updateable view as my main CRUD EO and then create a VO on top of that with additional EOs or VOs. But, I have found that I cannot add VOs to another VO. However, if I link the VOs then I have a master-detail which will not work for me.
For example, I have two joins to CSI_INST_EXTEND_ATTRIB_V shown in the queries below and need to have that show in the table displaying the CRUD VO’s data. It seemed that the best way to do this is to create a CSI_INST_EXTEND_ATTRIB_V entity object and view object. The view object would have two parameters, P_INSTANCE_ID and P_ATTRIBUTE name. Both the building and the unit are needed on the same record, and this is not a master-detail even though it might look that way. (A master-detail data control will not work for me because I need all this data to appear on the same line in the table.) So, I need help figuring out the best way to link these to the main (CRUD) view; I want as much of this data as possible to be filterable.
select
cieav.attribute_value
from
csi_inst_extend_attrib_v cieav
where cieav.instance_id = p_instance_id
and cieav.attribute_code = 'BUILDING NAME'
select
cieav.attribute_value
from
csi_inst_extend_attrib_v cieav
where cieav.instance_id = p_instance_id
and cieav.attribute_code = 'UNIT NAME'
Ultimately, I need to display a ton of data in each record displayed in the UI table, so a ton of joins will be needed. And, I need to be able to add records using the UI table also.
James

Hi Alejandro,
Sorry if I caused confusion with my first post. What I had in mind assumed that I could have a single CSI_INST_EXTEND_ATTRIB_V EO with a BuildingVO and UnitVO on top of it. So, I wrote the queries individually to show how I would invoke each view. When I realized that confused the issue, I rewrote the query to explain things better.
Now having seen your 2 queries. You need to create 2 EO. One for each table. Then create an association between the 2 aeO (this will be the join you are talking about). Then, you need to create a VO based on one of the EO and after you can modify and add the second EO (in here you select the join type).
After your done with this, youll have 1 VO that supports CRUD in both tables.
There were three tables in the query: CIEAV_BUILDING, CIEAV_UNIT, and T -- the main CRUD table. When you say that I should create two EOs, do you mean that they are to be for CIEAV_BUILDING and CIEAV_UNIT? Or, CIEAV and T? Assuming CIEAV and T, that sounds like it would allow me to show my building or unit on the record but not both.
By the way, everything is a reference except for the main CRUD table.
Look forward to hearing from you. Thanks for your help (and patience).

Newbie question about component and UDF usage.

This will be the 1st time I'm coding a component and UDF. I
kind of understand the concept but not sure about how to write it
in detail.Such as passing the parameter, etc.
I'm starting to write a user login, verifying users before
allowing them to enter into the app.
So I have 2 fields in my login form, Login and password.
Upon submitting this form, on the actionpage.cfm I'm calling
a component. This is how I call the component:
<CFINVOKE Component="cfc/loginaction"
Method="AuthentiCateUser" ReturnVariable="UserInfo">
Then in my Component I have the following:
<CFCOMPONENT>
<CFFUNCTION Name="AuthentiCateUser" RETURNTYPE="Query"
hint="Use for user login">
<CFARGUMENT Name="login" Type="Structure"
Required="true">
<CFARGUMENT Name="password" Type="Structure"
Required="true">

<CFQUERY NAME="Authenticate" DATASOURCE="sendfast">
SELECT * FROM tblcustomer WHERE Login = '#Login#' AND
Password = '#Password#'
</CFQUERY>
<CFRETURN AuthentiCateUser>
</CFFUNCTION>
</CFCOMPONENT>
When I run this code, I got error, it said :
The parameter LOGIN to function AuthentiCateUser is required
but was not passed in.
The error occurred in
C:\CFusionMX\wwwroot\KDt_Mod\userloginaction.cfm: line 18
16 : <CFSET
UserLoginInfo["Password"]="#Form.Password#"> 17 : 18 :
<CFINVOKE Component="cfc/loginaction" Method="AuthentiCateUser"
ReturnVariable="UserInfo">
19 :
My question is:
What should I do in order to pass #Form.Login# and
#Form.Password# to my UDF within my component?
I'm using CFMX 6 and Micrisift SQL 8

I've applied cfinvokeargument and my login and password were
passed to my component.
But I'm facing new problem: Where should I write my
authentication? should I write user authentication within my
component or
loginaction.cfm (the calling template)
What I mean by authentication is something like this:
<CFIF #Authenticate.RecordCount# IS NOT 0>
<cfset session.CustomerID
="#Authenticate.customerid#">
<cfset session.Name ="#Authenticate.Name#">
<CFCOOKIE NAME="UserLoginIn"
VALUE="12345_pn#Authenticate.customerid#">
<cflocation url="index.cfm?loc=home">
<CFELSE>
<script language="JavaScript">
alert("Username/password is not found, plese try again");
history.go(-1);
</script>
<cfabort>
</CFIF>
If I keep this code in my loginaction.cfm what is returned
from my function is not recognized by the component, the error said
Authenticate.RecordCount is not recognized.
Also I'm still confuse with what should I put in the
RETURNTYPE. If I put query, it gave me error, also, what is
returned by CFRETURN.
This is my component:
<CFCOMPONENT>
<CFFUNCTION Name="AuthentiCateUser" RETURNTYPE="Query"
hint="Use for user login">
<CFARGUMENT Name="login" Type="Structure"
Required="true">
<CFARGUMENT Name="password" Type="Structure"
Required="true">

<CFQUERY NAME="Authenticate" DATASOURCE="sendfast">
SELECT * FROM tblcustomer WHERE Login = '#Login#' AND
Password = '#Password#'
</CFQUERY>
<CFRETURN AuthentiCateUser>
</CFFUNCTION>
</CFCOMPONENT>

Newbie Question about downloading and installing Firefox

Hello,
I recently downloaded Firefox 2.0.0.3, got it all set up and used it for a while, I am the admin on this machine, my wife is the only other user, I logged in to her acct to make sure that FF was there, but it wasn't?? Thought maybe I should reboot, after the reboot, no firefox on my acct or hers! Completely disappeared, can anyone give me a clue as to what might be going on?
Thanks in advance,
oldhoghead
cheers

Common n00b mistake (joking about the n00b remark)
It looks like your running the program (Firefox) from the mounted dmg file. When you download Firefox, (and many other apps) it downloads as a .dmg file. Now, you probably have dmg files set to mount automatically when downloaded which is OK. You are probably launching the program from that mounted dmg file which is not OK. Here's what you need to do:
After the dmg file mounts, instead of double clicking it, drag it to your Applications folder and launch it from there. That's it. Oh, it'll also be available to all your machine's users as well.
Good Luck.

Newbie - confused about clips and "Unrendered"

Hello - Sorry for the newbie-ness. Just got FCE, watched the tutorials... Imported a .mov file, have edited the clip a bit and I have two clips in the timeline using "superimpose" for the second one, so that I could view both happening simultaneously. But when I try to play them back to view them I'm not seeing them, though I hear the audio of both clips.AND, when I press play the far right window says "unrendered," but when I pause I see the clip in the far right window. So, what am I doing wrong? Thank you very much.
Nick

Nothing. Superimpose puts one clip on top of the other. It does not adjust the transparency or alter the clip in any way to see the underlying image. If you want to do that you can do it by opening the clip from the timeline into the viewer and in the motion tab adjusting opacity, scale, crop, whatever.
The material is unrendered because it probably does not match the sequence settings. Check item properties for both the sequence and the clips and make sure they match in every respect.

Newbie question about logrotate and "olddir" option

I have just added "olddir /var/log_archive" line to my logrotate.conf (the rest is Arch default). Should I now move manually all these *.1 *.2 *.3 *.4 files from /var/log to /var/log_archive or will logrotate do that for me? And what with the files in the subdirectories like /var/log/samba/? Should I move them to /var/log_archive/samba?

I don't *know* the answer. But I bet that you have to move the files yourself. Logrotate doesn't keep track of old files. It just looks to see if they're there where it's currently configured to think they might be; if so it rotates them. So with your config changes, it will now look to see if there are existing .1 .2 etc files in /var/log_archive. (You may need to create /var/log_archive, if it's not already there. There may be a config option to make logrotate do this for you; but it's easiest to do it ahead of time and give the folder the appropriate owner/permissions.)
As to the subfolders, I suspect they will also need to be moved. In addition to the main /etc/logrotate.conf, there are also package-by-package config files in /etc/logrotate.d/. Look them over to see where the /var/log/samba {...} config block is. (And so on for all your /var/log/* subfolders.) I THINK you'll need to add an "olddir /var/log_archive/samba" command to each of those blocks; otherwise the rotated files will just be put into the top-level /var/log_archive.
This is all off the top of my head; so don't rely on it without checking against the manpage and google. But I thought it might point you in the right direction.

Newbie, Questions about 865PE and DDR500 ram

I just purchased an MSI 865 PE Neo2 LS board, Kingston khx4000k2/512 PC4000 DDR500mhz kit, and a Pentium 4 3.0ghz 800 mhz frontside bus cpu. How do u set it up for dual channel, and what would your recommended bios and D.O.T. settings be for the ram and cpu. Basically if you had this setup, how would u set up the bios and D.O.T. for it to run as kick *ss as possible but running stable?

First of all; I have that same mem. in 1GB. Secondly, EVERY MO-BO, CPU, AND MEM. MODUALS do not react the same. So that said, I would START by installing the MEM. in sockets 1-A and 3-B, That will enable DUAL DDR recognition. Next go into the BIOS and set MEM TIMMINGS TO SPD (Serial Presence Detect). Then go to FREQ. and VOLTAGE page and SET PERFORMANCE to FAST, AND MEM SPEED to AUTO. Then (on same page) you should up the V-DIMM VOLTAGE to 2.7V. SAVE AND EXIT.. Then if you DON'Thave any problem with the POST, you can go back in and start to play with the TIMMINGS, PERF. MODE, RATIO, and (If you choose, OVERCLOCKING)...MY sys. is running stable with (TIME 2-3-3-7-8),(PERF. MODE TURBO), (RATIO 1:1), (FSB 220, MEM. SPEED=440), (V-DIMM V=2.7)...Keep in mind that I MEAN STABLE, I am sure I could go more,BUT WHY?..And as you can see I have the i875 and the P-4 3.2...Sean REILLY875

Newbie question about C coding and SDK for iPhone app

Hello,
I am interested in trying to create an app. However, I have NO experience writing code I already have downloaded and installed the latest version of the SDK.
I know I have to learn: C, Objective C, and Cocoa.
I just picked up "C for Dummies" as a starting point. I figured the K&R might be a bit overwhelming to start with. Thing is, "C for Dummies" suggests doing some exercises in Text Edit and then using GCC to compile and test. But, then again, it has a copyright of 2004--long before Snow Leopard.
My question is, do I really need to do the exercises in Text Edit? Can I just use Xcode for entering the code and testing it? And, any suggestions for learning C and Xcode tutorials are greatly appreciated.
Thanks!!

But, I really want to learn coding and not just take the easy route by using Xcode.
The simplification of using Xcode may have been a bit exaggerated throughout this thread. You will still learn how to program full-on by using Xcode -- it's not like you're taking a shortcut or anything. Well, technically speaking, you are, but Xcode is the expected way to develop on a Mac nowadays -- it's how Apple expects you to develop and how most people are doing so. Should you choose, you can taking a deeper dive into the inner workings of compiling and whatnot by using a text editor and the Terminal, but keep in mind that the extra complexities here could complicate the more important overall goal of learning the basics of how to program. There is absolutely nothing wrong with simply using Xcode for the novice part of your programming days. In fact, it's probably the path I would recommend. Some here might suggest that it is beneficial to learn the intricacies of compiling through the Terminal and whatnot early on, and they are right -- it is beneficial, but the benefits of taking a route (at least for the time being) that allows you to focus on the more pressing issues of learning how to program without having to delve too deeply can be just as beneficial. After all, it's not like you can't go back and learn how to compile via Terminal later on -- that's what I've done (or, rather, am in the process of doing).
I always thought Terminal was something not to mess with.
Not so much. Like most things in programming (or life, for that matter), the Terminal is something not to mess with +if you don't know what you're doing+. Basically, it breaks down like this. The GUI that Apple has created for you in Mac OS X (by GUI I mean "graphical user interface" -- the icons and windows and buttons and so forth that you use to perform tasks on your Mac -- in other words, everything outside the Terminal) is geared toward the common user who does not need to access advance aspects of the system's functionality. Consequently, it makes common tasks much simpler to perform, but in the process it hides some of the deeper levels of the system's functionality from the user. This is a good thing, since most people wouldn't know what to do with this functionality and would create problems for themselves if they did have easy access to it. However, for some users who know more about the inner workings of the operating system, there needs to be a way for them to access this functionality, so that they can do certain things (like accessing certain files and performing certain tasks) that they would not be able to do using the Mac OS X GUI -- that's what the Terminal is for. It allows the user to operate the system on a lower level. In other words, it allows you to get closer to the operating system. This is good in a way, because it allows you to perform tasks that you wouldn't otherwise be able to perform by giving you more control over the operating system, but it is also bad in a way, because it can allow you to mess up some of the deeper aspects of your system if you don't know what you are doing. Most people leave the Terminal alone for this reason, and because they have no need of it, but if you want to be a good developer, you're going to have to work with it sooner or later.
Now, with all that being said, it's not that easy to mess things up using the Terminal. It's not like your system's going to crash if you misspell a command. All in all, the Terminal is very forgiving, but it will do what you tell it to do, even if you tell it to kill itself, and it is for that reason that you need to know what you are telling it before you try to tell it something. If you understand what you are telling the system, than operating on a lower level and being closer to the operating system is completely safe.
The Mac OS X operating system is based around Unix, so when you are communicating more directly with the operating system by using the Terminal, you are interacting with its Unix core. For this reason, using the Terminal goes hand in hand with understanding Unix. So, if you're going to want to use the Terminal, then I recommend you get a good book on Unix to teach you the basics of Unix commands and shell programming and whatnot. Any book on Unix will do, since more or less everything you learn will be applicable to the Mac OS X's Terminal, but there are a few that are specifically directed to Mac OS X users, and that always makes things easier. Most of these books aren't updated to cover past Tiger, but this really doesn't matter (someone correct me if I'm wrong). A few examples are O'Reilly's "Learning Unix for Mac OS X Tiger" by Dave Taylor or Peachpit Press's "Unix for Mac OS X Tiger" by Matisse Enzer. Also, the book "Unix Programming Environment" by Kernighan and Pike is an excellent book on Unix, although fairly outdated, so I would highly recommend it, although I would recommend it as a supplement to another, more recent, Mac-based Unix book and not as your primary source for learning Unix. The skills you will acquire from these books will help you later if not sooner, so I recommend giving one of them a read at some point, whether you are planning on compiling using the Terminal right now or not.
Anyways, I hope this helped to clear some of this up for you, and please let us know if you have any further questions.

Updated to Mavericks. Now theres tons of activity in my terminal and my activity monitor doesn't seem normal. I want to think someone's hacking me, but i need experienced help please!

I spent all night trying to fix this. It seems to me that someone has been trying to hack into my system with all of the random codes/lines in my terminal and i have all of his foreign IP addresses. And now i get this strange message that popped up in my terminal. Idk what it entirely means? I would very appreciate if someone could just walk me through this. Thank you very much.
First time poster. I have Macbook Pro. OSX. Just downloaded the new mavericks. I'm i have my firewall on. I stay secure. I run Netbarrier, Virusbarrier, IdentityScrubber.
I know something is a little odd or just doesn't make since about my activity monitor. Then my WiFi was hacked last night and this person was writing tons lines of commands/codes that i found in my terminal and my activity monitor doesn't look normal, and I've only been a mac owner for about a year now and i'm learning more and more but while trying to figure out what was going on this message popped up which concerned me the most. Any help would be most appreciated, thanks guys. I have my terminal full of his foreign ip addresses i noticed, and a lot of other commands and lines he wrote out that i definitely did not type myself. Can anyone give me a hand on this? Thanks

<Personal Information Edited by Host>

haha, so now i'm thinking. I'm learning the terminal as fast as i can but there are several lines of codes and commands in there that throws up red flags to me that i don't fully understand. It just looks fishy too me. It would be highly appreciated if someone could just check this out just to tell me that i don't need to worry about it. Or point me in the right direction. I just feel un easy about this. ha.

Best avenue to file complaints about bill and have them resolved

I have been a customer since before 2005 and went with Ntelos in November, I called the night I was at Ntelos to ask Verizon what my contract buy outs were and I was given the prices. The representative tried to offer me whatever promotions she could offer (there wasn't many) and I declined service (there she should have took the initiative to ask about disconnecting). Since my bf opted to keep his number his phone disconnected automatically. I was told my Verizon phone would cycle off within 24 - 48 hours by the Ntelos rep. That was not the case so I called verizon to ensure my phone would disconnect and they told it would at the end of the billing cycle (december 20) which makes sense. I understand I would be responsible for the November - December. Anyways, December 20th rolls around and mind you I've called already to ensure it will take place and it doesn't. I phone in and come to find out the person who took my orders didn't complete the disconnection and now I have to wait until January 20th for it to cycle off and I can finally pay my bill! Well get this in my November - December bill they've charged me $51 for Monthly access (I have a work discount) and $49.99 for insurance and smartphone access for 12/21 - 1/20 and won't refund my $51 as they say that I called out on the phone. I turned the phone on and had voicemails that I think I checked around the time period that they are mentioning (1 day) and that data was used (1 day) I had no outbound calls after December 11th my birthday. Because there are no comments in my account (that I specifically asked them to make) my phone should have been disconnected when I had called in the first of December... really!?! The phone should have been turned off regardless and it was one day out of 30 seriously? I mean the phone has been turned off this whole time and literally only checked to make sure Verizon did their job. I CAN'T HELP IT YOU DON'T KNOW HOW TO DO YOUR JOB, I PUT THE EFFORT IN MULTIPLE TIMES TO LET YOU KNOW MY PHONE NEEDED TO BE DISCONNECTED YOU SHOULD HAVE KEPT RECORD OF IT!!! What really heats me up is that I was told a supervisor would give me a call back after they got out of a meeting and I have not rec'd a call back yet. VERIZON Reps/Supervisors your customers are the reason why you have get a paycheck, I suggest you start treating them a little better. You can't seriously tell me giving me back my $51 for service I DID NOT USE (except according to you for one day you can't even give me details about?) is really going to hurt your pockets. I've been jerked around by your reps for the last 2 months as one told me my contracts were up in January and I shouldn't' be charged for disconnection fees at all, she credited me those termination fees but they later got rejected (after she said her supervisor approved while I was on hold) and NO ONE HAD THE COURTESY TO NOTIFY ME!
I've worked in customer service before and I'll be first to tell you that your reps are not trained very well and you have horrible ethic! You should not charge your customers for an error that was your fault; especially since it was your reps that I asked specifically to note my account and didn't (this isn't my first rodeo with you all, it should be standard procedure to give your reps time to comment before throwing them into another phone call). I'm not doing this for my health here, that $51 could buy diapers and baby food for my daughter and you are crazy if you think I'm going to let it slip through my fingers to line your pockets. I will keep escalating it until you do something about it and I don't care that you already gave me an inconvenience credit I deserve that and my $51 so don't try to justify it that way! This has been way more than an inconvenience, so don't worry I'll inconvenience you as well!

With my new provider I am only using the chat function to settle anything with them so I can save the conversations I've had with them (not that I've had any issues thus far). It should be standard procedure for them to comment your account while they are on the phone with you before hanging up. I should have been annoying and asked them to read back their comments (hindsight ugh!). I'm sorry that you are having to deal with this as well, just know you are not the only one receiving horrible customer service. I'll share with you what I wrote on their Facebook page. They really should take some accountability for their actions and have better follow up on resolving issues (or train their representatives better). I can't stand having to talk to another person time and time again explaining the same thing i just explained to 3 people before them.
Almost immediately, I received some attention after posting this:
Dear Verizon,
I am appalled, especially after reading your credo, that you are refusing to credit back money that is owed to me because your representatives didn't take the necessary time that they should have to comment (after I specifically asked) in my account after I diligently called in multiple times to ensure that my disconnection took place when it was scheduled to and was told that it would (an ongoing issue since the beginning of December). Come to find out that the representatives I spoke with prior to December 20th didn't do their jobs correctly by not entering the disconnection orders in. "Verizon Credo- a set of principles that describes our culture of integrity, respect, performance excellence and accountability. The Credo is a blueprint that directs us to live up to the highest standards possible when serving our customers, shareowners, communities and each other." Let me school you on something here because it appears that you just put that mission statement up on your website 'cause it sounds good, you certainly do not follow through! Accountability: Noun - the quality or state of being accountable; especially an obligation or willingness to accept responsibility or to account for one's actions (i.e. public officials lacking accountability). It doesn't matter that you cannot find any proof in my statements it doesn't change the fact that it happened and I am not a liar. I seriously wouldn't exhaust this must effort had I been lying. I'll take this a step further and reference your statement "we focus outward on the customer, not inward. We make it easy for customers to do business with us, by listening, anticipating and responding to their needs." First of all, when I made my initial call to you all asking what my contract buyout prices were and your rep tried to offer me promotions (or lack there of) to keep me as a customer and I declined she should have "anticipated" my need for disconnection. I shouldn't have had to jump through so many hoops to get my service disconnected from you all and pay my final bill. It's not my fault that your representatives weren't trained well enough to correctly put through disconnection orders. Based on my interactions with your customer service I could see where people would disconnect their services regularly!!!!! You are not making it easy for me to severe ties with you and conduct BUSINESS and you are not responding to my NEEDS. I think you forget that I could be a potential customer in the future. If it's one thing I learned from my Communications Degree is that negative feedback will reach more consumers vs. positive feedback of a company and how they handle their business. I have 1,000 plus facebook friends and twitter followers so I'm pretty sure my negative experience could reach quite a few people! You say you have integrity? How is it moral uprightness to charge me for a whole month of service (regardless if the phone was turned on once) for a billing period that shouldn't have existed if your customer service reps did their job correctly? I suggest that you all take a good look at the way you are treating your current customers because we are the reason you get a paycheck! You should make your customers a priority especially if they've been with you for 10 + years regardless if they are disconnecting service or not! How about following through, taking ACCOUNTABILITY and having that supervisor representative call me back from my phone conversation last night like I am a priority (how every customer should be treated) and helping me get the money that I am owed, regardless if the phone had been turned on for a short period (your rep couldn't even tell me what numbers I supposedly called - exactly the phone has been off since December 20th if not before unless turned on to confirm disconnection)! Oh but let me guess did you all forget to put that in my account comments as well? Probably like there is no mention of the formal complaint I filed against some of your representatives that there was supposedly no ticket number for. I thought I was going to regret leaving Verizon for another provider but it turns out that I only wish I would have left sooner and actually gone to a authorized dealer/ Verizon Store to process my disconnection because your customer service line is a joke!

How do I start Firefox 4 from KMenu when I downloaded and installed Firefox4.0.tar.bz2 (only launches from terminal), and 'apt-get' installs Firefox 3.6.15 even though I tried to "--purge" it from Linux?

I downloaded and installed Firefox 4 RC using tar.bz2 so that I could still use Firefox 3.6.15 as per normal, having to start Firefox 4 using the terminal which worked great (except for many videos on different websites). When Firefox 4 was released, I suppose I was in a hurry to get it to work normal from my menu, but it kept saying that 3.6.15 was the latest version (I'll be quite embarrassed if it wasn't available for Linux users - I do love Firefox!). I did something silly, like purge Firefox from my operating system (Kubuntu 10.10) and when I reinstalled it was still 3.6.15 (it wasn't really downloading, but unpacking). Am I in too much of a hurry or is there a fix-it? I can use Firefox 4, but only through the terminal and I suspect it is slower than it should be. I would like only one version now.

First, that cannot be an iBook G4 as that machine cannot run Snow Leopard let alone Mountain Lion. To run Snow Leopard it has to be an Intel processor, not a G4. What does it show as the Model Identifier in About This Mac, More Info, System Report, Hardware, Model Identifier?
Second, if you have erased the hard drive there should not be remnants of any prior content. Even though Disk Warrior is saying nothing is wrong with the hard drive, it sounds as though there are problems. You may want to consider simply replacing the hard drive so there are no questions about faults. A good source is OWC, http://www.macsales.com where they also have on-line videos showing how to do the replacement.
Third, you could also try again to restart using the Snow Leopard DVD/CD and use Disk Utility on that install disk to erase again, and do it a couple times, then try to install. If it continues to refuse, then it sounds as though there is a fault with the hard drive.

Am i missing somthing about speed and coverage please help very very slow speeds!

i get speed test results of 1/10 of a megabyte per second all of the time regularly that is 100kbps many times it is also like .06 mbps. it takes forever to load web pages and i cant watch video! i called verizon many times becuase i can get 5 bars of evdo. 2 miles away in the vzw store my usb modem worked fine (about 1mbps) and it works better at home like @ half a mbps speed in the early morning like @ 6am. tech support told me after opening a trouble ticket they found this is a marginal coverage area and they will not be improving it in the near future. i dont know how the coverage area changes from morning to the rest of the day. i asked about possibly getting out of my contract and they said i had to still pay an early termination fee or produce a death certificate or military papers saying i was being deployed overseas. furthermore i was told since this is mobile broadband i should just go somewhere else when i need to use the mobile broadband card. i had so much trouble logging into this site because verizon keeps saying my password and username for this forum is not correct so i have to keep trying to make new ones. then somtimes just when i thought i had logged in it says the server is forbidden from accessing this site, which is the only time on any website i ever got this message. i just wish i could get the speeds they aadvertise or somthing even close to it so that i could load web pages. i feel like i am being forced to change to another wireless provider and pay an early termination fee because i cant do basic work and load web pages which is what i was promised according to their map which says i live in a good coverage area. i pay my bills on time every month and so i feel like i am not being treated fairly as a customer. am i missing somthing?

If it works everywhere else, then it does sound like a marginal service area. If no one is making use of the tower, then there could be a better signal to your residence in the morning. During peak times, the signal might not be as strong and could be degrading to the point where your speeds/connectivity gets questionable. Being inside a structure and what materials can also have an adverse effect. Also, your verbage is confusing. 100 kilobytes per second is a pretty average speed for EVDO. 1/10 of a megabyte a second is the same speed. Unless you are referring to .1 megabits per second, that is a whole different story. I'm assuming the latter if you are having problems loading pages, but again, if it's a marginal area VZW is showing on their side, that's probably the case. Also, the 3G map might not be the same as the Voice/1X map in your area. Maybe double check the map you're looking at.

Nervous about terminal.

Hello there Mac community. I just have a quick question that I would like to have resolved. You see, I am a little nervous about entering terminal commands. I most likely shouldn't be, but I just love my new iMac so much that I'd hate to mess it up some how. Please take the time to answer the following questions. Thanks!
1. Have you used terminal? Has the service made your user experience better, or worse?
2. Are there any commands that I should keep away from? What are the risks associated with entering commands?
3.. Can you reverse commands? If so, is it easy to do or more complicated and potentially costly?
As stated above, these are most likely foolish questions. However, I would appreciate any assistance I get as no other people seem to have the answer.
Thanks in advance!

1. Have you used terminal? Has the service made your user experience better, or worse?
Yes. There are some things that it is not possible to do easily without using Terminal and others that Terminal makes much easier if you know what you are doing.
2. Are there any commands that I should keep away from? What are the risks associated with entering commands?
The rm command (remove file or folder) comes to mind here. You have to authenticate with password in order to use it, but it is quite possible for you to immediately delete files irretrieveably using this command. Be sure you really want to do this and do not mistype file paths. A good habit is to not type file paths but let the Terminal app fill them in by dragging and dropping the item you want to use/delete/move onto the Terminal window. It then fills in the path.
3.. Can you reverse commands? If so, is it easy to do or more complicated and potentially costly?
Some you can, some you cannot. It is best to treat your commands as if they are irreversible. And have a backup.
There are some great books available for Terminal. If you do a search in amazon.com for Mac OS X Unix you will come up with a number of useful titles.
Best of luck.

This might depend on how you made your installer. If it is a flash pen installer that you made yourself, depending on how you made it, it has consequences on what is installed.
I am assuming that you have made an installer?
If you have and you did it manually, without using the Terminal command then it is a know caveat that a recovery partition is not installed as part of that procedure. The second method to create a bootable installer, using Terminal, will allow and install a recovery partition.

Alternatively, have you zapped the PRAM and SMC, prior to trying to install?
See here: About NVRAM and PRAM
Some of these might help or even answer your query...
Good luck.
