Ubuntu Security :: Opening Pgp Files
Jan 14, 2010
After upgrading to 9.10 I am having trouble opening my old files encrypted with pgp. My keyring is still on the computer as I did an update and not a clean install. The problem is that I get a message saying that there is no pgp/mime program installed to open the file. Which program should I install to fix this?

I just would like to know how to ask for a password in opening an application in ubuntu. The scenario is like in opening any application from system administration and the system will ask for a password to execute the application.

How do you open a program, in this instance "Zenmap", from the desktop in a user account when it requires root privileges? Is there a way to be prompted for the password, the same way, for instance, you're prompted when mounting a new file system or making a change to the system? I tried entering 'sudo /usr/bin/zenmap' when creating the shortcut, however that didn't work.

I'm trying to open port 119. I already have a few ports open. I've used webmin to open both incoming and outgoing ports. iptables --list --numeric gives me:
Code:
...
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:10000
[code]....

I'm currently using Slackware 13.0 and have my machine behind a Linksys DD-WRT router. I believe the DD-WRT software has all ports blocked by default so opening up my machine for SSH login would only leave my system vulnerable at that port. To give an extra layer of security for that opened port, I've created the following script that would be invoked as the users' shell.
#!/bin/sh
#if SSH_CLIENT defined run nail with $SSH_CLIENT as an argument
if [[ -n ${SSH_CLIENT} ]]; then
[code]....

my son is 15, autistic and mentally retarded. he is moderate-low functioning and loves to watch barney the dinosaur, thomas the tank engine and other young children's programming on videos on his computer. he can talk in a limited way and can read out loud at about the first-grade level, though he seems to have little or no comprehension of what he's read (hyperlexia).i'm having problems with viruses and spyware because he lacks the judgment that keeps the rest of us from clicking on every window that pops up. we've had a particularly nasty crop of ad-ware viruses lately that pops up graphic porn ads even when the browser is closed. i've had enough of this.
the computer is an ancient dell dimension 4600 desktop (circa ~2002) running windows xp. i've run ubuntu from a live cd and installed flash as a test. videos videos play fine, so that's not a problem. i don't really want to replace the computer becasue it still works and is only used by him to run firefox. i am willing to buy a new computer if that turns out to be the only option.i've been using ubuntu exclusively on my laptop for several years and i would like to remove windows from his computer and replace it with ubuntu. i'm wondering how i can make his computer as accessible as possible to him while not sacrificing too much security.my son has very poor fine motor control over his hands. he can use a mouse with some difficulty, but using a keyboard is out of the question. he can use the mouse to click on the shortcuts to his favorite videos, but i can't think of how he would be able to enter a password for his account. not only does he have the fine motor problem, but he is not able to remember any usefully secure password.
does anyone have any ideas about how to make his computer accessible to him without opening a gaping security hole? two ideas that i've kicked around are creating a user with absolutely the minimum privileges required to use firefox and no password or finding some way to enter a password that doesn't require a keyboard. i haven't come up with how to implement either of those ideas successfully.

I didn't see another thread about Google Picasa being blocked by SE Linux. How do I tell my machine to allow it to run? I have the same problem with a program called Smartboard that I have installed but can't open.

I'm running 9.04 jaunty. I made a file in gimp and saved it as .xcf. I want it to be a pdf file, so I try opening it with open office drawing, but it keeps opening it with the word processor instead. The word processor starts the file if I do a right-click 'open with' on the file on my desktop, and even if I use open from the file menu in drawing itself. I'm wondering what to do to get drawing to open this file. Is it that .xcf is not supported by drawing?

I have this file that is about 3.6GB, I'm trying to open it through wine. But it gives me an error saying I can't open it. I'm not sure if this is a problem with wine, or do I need some special code to put in the terminal?

I have a laptop that's not up to par with opening 1080p video. I do however have a PC that can. I've connected my laptop to my TV as a media center. I can remotely access files from the PC to play but because the laptop's resources are being used to play it I still encounter some slowdown. Is there any way to remote access the other PC while using its resources to play the video?

9.10 Karmic Koala. issue running gscan2pdf. It works fine for scanning, but I want to use it to concatenate / edit existing pdfs. But it hangs on opening PDF files (Import of picture from PDF works fine, but that's not what I need). I tried with a lot of PDF from a lot of different sources.
I added the line "resolution = 200" in the .gscan2pdf file to solve the issue where scanned PDF won't save.
I tried to reinstall the package with Synaptic without more success.
Here the output with debug flag :

What is the command that opens .desktop files? Gnome-open opens it in an editor. I need it to open the application that it refers to. Even better would be general method to find out what application it refers to.

I've been getting annoyed with the way that Firefox opens files for me. I used to have it so that they would come up with a window that asked whether I wished to save files onto the hard drive or simply open them. When choosing to Save, they would go to my Desktop. Because I mainly save files from my Uni website, they are generally .pdf files. N for some reason, they open in the Firefox window, so then I have to go to File, Save, then choose where I want to save it. It would be more efficient if it worked the way it did originally. How can I get the settings back to the way they were? I am running Ubuntu 9.04 and Firefox 3.0.19. Because I use a shared computer, I'm not sure whether the version of Firefox has been changed.

I switched from Windows XP to Ubuntu, I zipped a large number of important files, giving them a CIA-grade password. Is there a WinZip clone available for Ubuntu that will enable me to open those password-protected files? Or can I only do the unzipping on another Windows machine?

I really hate this warning when I try to open certain types of files in gedit: (using ubuntu lucid)
Quote:
Do you want to run File.c or display its contents?
"File.c" is an executable text file.
Open in Terminal; Display; Cancel; Run
Is there any way to remove the warning? I have never once clicked anything other than display, and when I'm opening lots of files, having to hold down ALT-D to get rid of these warnings.

I install a nautilus plug-in which in turn installed the elinks browser and now all of my .html files are opening in elinks instead of firefox so how do I get .htm/.html and other web type files to open in firefox instead of elinks.
I also tried removing elinks from my system but then the files just open in gedit so again how do I associate .html (and other web files) with firefox.
BTW firefox is already set as my default browser in System > Prefs > Prefered Applications > Web Browser

I have a wav file bigger than 8GB. i recorded it on a windows PC. unfortunately wav files cant be bigger than 2GB. somehow i got a file that is almost 9GB. I tried to chop the file under ubuntu into smaller pieces to open it part by part. i used gnome split to divide the file and made 10 parts out of it. now i have these parts of the data which i cant read with no program except for gnome split to merge them together again - which would only bring me to the beginning of my problem. so my question is: is there any other way to open/ split&open a wav file of that size or maybe a way to open the splitted file partially?

I just moved from Ubuntu to Debian, managed to get the WiFi printer working, installed flash player etc. Just seemed to have trouble opening files over the LAN, is there a firewall setting I need to set. Files work fine if i copy them to the desktop and open them from there but not over the LAN. I have looked on the web with no luck.

I have some text files (Just plain text files, not OpenOffice files or anything) and when I try to open them in Windows they are all one line. I think I read somewhere that Linux uses for new lines whereas Windows uses or something... I am using Kate to edit them, and I have a LOT of files to fix so...

Running various applications, including Open Office, I need to open files from my external hard drive, from within said application itself. But the file menus for all my applications list only the files of my primary hard drive, and I can't look at other drives. Surely there must be some way to do this.
