Try this in your browser: http://localhost:631/

This is direct access to the CUPS interface -- avoiding the Ubuntu Printer Dialog.

What kind of interface is the printer?

I dragged your file into Libra with a copy and paste, then saved it. Now it's an ODT file.
So I went to the 631 link and searched for the file CNCUPSMF4100ZS.ppd and the search comes back, "No matches found".

I have no idea what kind of interface the printer is.

You are making me look bad.

What did you drag where? And copied and pasted what? And saved it where? And why?

Searched what and where?

When you went to http://localhost:631, what did the screen say?

Somebody gave me a Cisco router today. Maybe I can install that.
Now you've got the right idea...

When I open your link in a new tab, it looks like a usable file which defines how to address a printer. I tried to drag&drop the title you posted on this page to my desktop so I could rename it and tell the printer installer to search for the driver on the desktop. It won't drag&drop but I could select all the text and copy it to Libra Writer. Can I rename an ODT file to be a PPD file? I tried that and failed.

But enough with how to do it wrong. What am I supposed to do to make the CUPS file discoverable by the printer installer?

In Windows it would be a .txt file renamed as a .ppd file and I would tell Windows to Browse and choose Desktop but I can't make a .txt file in Ubuntu because there is no program to write a .txt file...or I don't know what to call it or where to find it.

But I don't. Because you said this:

Your missing my point. I said it will help, but as a node on the internal network, it will not prevent it from responding to an attack. Linux will still respond to the attack, just a little slower. Also, a Linux box usually isn't the only device on the network to worry about (at least not on mine), there are other devices that will also respond. The best way to prevent the attack is at the connection to the ISP with a good firewall router. If your connection to the internet is provided by a linux firewall, by all means, be sure its OS is hardened and configured to prevent this sort of attack.

I like Linux....I've used FEDORA, CENTOS, FreeBSD, OpenBSD, OpenSUSE, SUSE, but I wouldn't recommend it to casual Linux user as a perimeter defense device (firewall) since it takes experience to really configure it properly. A good firewall router has this protection built in and is easier to setup.

Please stop arguing with joeyd. That is not helping me stop my one wireless router and one computer from annoying my Internet Service Provider.

I don't know why formatting the C: drive and re-installing Vista didn't fix the problem when installing Ubuntu did fix it. Given that these are the only things I changed, I think you can stop arguing about why it's the routers job.

Not arguing....just replying to the post.
I will say no more.

I didn't mean to cut you off with a sharp blade, just direct your contributions toward the topic of the Thread and the observed behavior of the components.

@#12, I haven't forgotten your printing problem. I had to get some sleep last night. Let's do this step by step.

#1: How is the printer connected to the PC?

I haven't received a threat from my ISP for two days. I still find incoming Smurf attacks on my router log by the hundreds per day, but apparently My computer is not sending any.

My printer is on a USB cable.

I just downloaded 15.10. I'm gonna burn the ISO to a DVD and be back in...however long it takes to install. Probably most of an hour.

Wrong. Ubunto 12.04 failed to burn a DVD. I can re-install 12.04 or 10.04 and try again, or go to a friend's house and burn 15.10 to a DVD.

This isn't going to happed this morning. The weather is right for working outside and the car upholstery will be ready in 4 hours. I have physical work that needs to get done today.

When you are up and running, open a terminal -- use <ALT><CTRL>T to quickly bring up a terminal.

Type:

lsusb at the $prompt, and copy the results here. #### wayneh Joined Sep 9, 2010 16,114 I'm a little perplexed at the strategy to solve this problem by switching to an unfamiliar OS. (I'll admit it would make more sense to me if #12 was becoming a Mac user.) I mean, the problem seems to be a small amount of malware that infected a Windows system. Wouldn't it be easier to 1) Use a utility to scan for and remove malware, or 2) Update or re-install the system, or 3) Reformat and install, or 4) Boot from another drive, perhaps a brand new one. I saw that #3 failed. That seems impossible, unless the malware put itself into the drive's boot loader. I'm just saying that I would exhaust every possible avenue within the OS I am familiar with before I would even consider a new OS. Heck, I'd find a new computer before I did that. But that's a Mac user perspective. #### joeyd999 Joined Jun 6, 2011 4,271 I'm just saying that I would exhaust every possible avenue within the OS I am familiar with before I would even consider a new OS.

Thread Starter #### #12 Joined Nov 30, 2010 18,160 I think I'll try feeding this hard drive the Vista disk. If the poison is in the old hard drive I can stay with Vista and forget this struggle to get a printer running or find out why Ubuntu doesn't seem to have anything that will make a .txt file. I can hope Ubuntu didn't change my partitions, but I'm not optimistic about that. Right now, I'm at the end of a rather physical day and feel myself slipping toward the shower and the bed.

ind out why Ubuntu doesn't seem to have anything that will make a .txt
Right click desktop. Select "Create New Document" -> "Empty Document". (New document magically appears on desktop).

Double click new document to edit.

Alternate: Press "windows" key -- or select "search your computer" icon at top of launcher. Type "text" and appropriate apps will from which you can choose magically appear.

I thought AAC had a policy prohibiting profanity, and yet, I have read the word "Vista" several times in this post. Where are the Mods when you need them??

Let me know when/if you wish to pursue this.
