xguest not showing up on GDM.

I'm new to Fedora and I'm using F17/Xfce.

One of the first things I did to 'acclimatise' was remove selinux. Then after I got more familiarised with the system I decided to install xguest, which brings selinux back.

xguest never appeared as an option in GDM and I thought it was because I had selinux disabled (xguest requires selinux in enforcing mode to work).

I did all this in a 'not in a hurry' pace. So one day I installed xguest/selinux, other day I set selinux to permissive mode (and made sure the relabelling was all fine) and today I set it to enforcing mode.

But xguest still doesn't show up as an option in GDM.

:confused:




KDE version looks good

Hello all :)



I'm properly impressed with 17 beta KDE. I've been using Linux full time for a little over two years, got Debian stable on one computer, I'm happy with that, but I'm now looking for a KDE distro with newer software for my work computer. Tested a bunch, and decided to install Fedora once the version is final. Little - and some not so little - things that were buggy in other distros under KDE work well in Fedora, so I'm either lucky with those instances or it's actually a solid distro :) plus, I don't think I've seen such good font rendering in Linux before, or Firefox so well integrated into KDE.. last time i tried Fedora I was new to Linux so even setting up codecs was a struggle.. this seems very different.

so here's why I post this: considering that I've been using this beta on a test computer for a short amount of time, I'd really appreciate the insight of anyone who's been using the KDE version on a daily basis, preferably for work. Their thoughts on the distro's general usability, stability, and so on. I know it's a very broad question, but I don't mind broad answers, that can still give me valuable info.

Thanks a lot and apologies if this is posted in the wrong place.




[SOLVED] Where is final TC1?

Anyone have an idea where final TC1 is? It was supposed to get built yesterday according to the schedule and the FESCo meeting.




Graphene lenses for electrons

Quote:









highly strained graphene impedes the flow of electrons, slowing them down and altering their trajectory. Scientists believed this effect could be used to focus electrons to a fine point — similar to the way an optical lens creates areas of refraction, or bending, to shepherd light to a point.








Do I really need Network Manager?

I manage RHEL servers at work. I configure interfaces manually by jiggering around with the scripts in /etc/sysconfig/network-scripts.



But that's not what I'm asking about. I just want to provide some bona fides.



My Toshiba laptop has been happily running Fedora since F13. I used preupgrade to seamlessly upgrade to F15, and a few months back to F16.



A week or so ago, the wireless link began to flake on me. KDE Deamon would request access to the wallet, and I'd be asked to type in the "secret" for my wireless network. I couldn't actually get this to work, so I'd reboot. This became more and more common and last night I thought I'd remove and reinstall the connection.



Since I knew how to muck with those config scripts . . . how hard could it be?



Well, two concatenated words: NetworkManager. Wrapped around my laptop's network devices like Borg Implants around Jean-Luc Picard's amygdala.



In /var/log/messages I see my laptops's wireless interface get recognized, assigned wlan0, and then declared "managed" and made unavailable.



I've tried using NetworkConfiguration GUI, but I just can't get wlan0 to the point where it can find my home network.



So . . . what's easier? Learning the convoluted muck of NetworkManager, or uninstall it and try to get it working manually?



The only "gotcha" is that this is a wireless connection, and I suspect that NetworkManager is providing the "hey, there's your wireless network, I'll take care of connecting and providing the right keys" service.

Moserial won't send a file

I'm trying to use moserial to upload and download ASCII files to and from a Mitsubishi Meldas 64 CNC controller.

I have no issues downloading the files, but I can't seem to get moserial to recognize the controller for uploading. The pop up just gets stuck at "Waiting for remote host" and then closes the pop-up.

Any insight into where my problem might lay would be appreciated.



Here are the settings I'm using:


Code:


[port_settings]

device=/dev/ttyUSB0

baud_rate=9600

data_bits=8

stop_bits=1

parity=2

handshake=1

access_mode=0

local_echo=false

wpa_passphrase mysid mypassword >/wpa.conf





wpa_supplicant -K -Dwext -i wlan0 -c /wpa.conf



I get the following over and over again



Tring to assoiate to MAC (SSID:'mysid' freq=2412MHZ)

Associated with MAC

What am I donig wrong?

Printer not Working

Hello. I have been using Fedora 16 for a few months. I was using the standard distro, but after needing to reformat my hard drive, I installed Fedora16 Design Suite instead. When I was using the regular version, My printer (HP Deskjet f4590) worked just fiine without needing to install anything extra. I plugged it in and it worked fine. Since I've been using 16DS, it hasn't worked. I have tried all kinds of driver, and the hplip, and it still won't work. My computer recognizes the printer, but every time I try to print, it tells me it's not connected. Does anyone know what's going on?

grub>



This is what I get when I boot my dual boot (win 7, Fedora 16). Could you guys help me out to get my system booting again, please?



I rebooted to a installation fedora 15 cd, and I get bash, but I have to say thats how far I get. I would like to get my hands dirty on this, cause this happens quite frequent when trying and installing distros, always something screws grub.



Thanks in advance community.

right so Im trying this so far, but Im kind of blind here:



grub> set

color_highlight=black/white

color_normal=bla

pager=

prefix=(hd0,msdos6)/grub2

root=hd0,msdos6



when I enter ls:

(hd0) (hd0,msdos7) (hd0,msdos6) (hd0,msdos5) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1

VPN and Firewall

I am trying to connect to a vpn from my home computer. It uses Cisco vpn anywhere and downoads and starts a java cisco client.



I get the following message:



The certificate on the secure gateway is invalid. A VPN connection will not be established.



I can also connect to this vpn at an office. When I am there I get a certificate problem notification, but, I have the option of ignoring it.



Is this something that is being done by the firewall? Can I add this gateway as an exception if it is?



TIA

wget when full file name not known

I'm trying to automate a daily file download that I have to do via remote desktop by using wget in a cron job. However, I don't know the full file name without checking manually (it changes every day). The format is the following: http://blip.tv/file/get/Demnow-DemocracyNow[day of week][month][day][year][random garbage characters].mp4



I can use the date command to get that information, but there's no way to figure out the garbage characters except manually (they change each day, unpredictably). They don't affect anything, so I tried to use a wildcard, but I can't find a way to make that work. How can I automate this?

Don't tell Debian but...

Last night I decided to leave my 3 year old Debian install for Fedora. Same install mind you. It was just a spare of the moment thing. I had used Fedora back in the day when either Fedora Core 1 or 2 was around. I can honestly say Fedora Core was the first distrobution I had ever sucessly installed. I can see a lot of things have changed.



So anyways, I few questions came to mind that I wanted to ask. I could always of course look them up myself and I've found the Fedora wiki to be very helpful but then I would have no reason to conversate with all you fine people. :D



I've been reading a lot of different methods to installing a minimal base system. Pherhaps there is an option in the full DVD install? I just can't be bothered downloading that large of an image. Is there an offical way to install just the core system? I'd like to build my Fedora system by picking and choosing instead of having all of these meta packages installed.



I'm using the KDE spin of Fedora. To be honest, I've just started using KDE. I've been a XFCE guy for a while but decided to try it and I just never left. How well is the KDE side of the distrobution maintained? Better than most? Just a much as the default GNOME? Besides the unwanted application such as the alarm clock, I'm rather impressed with the install. A few distros have been known to just drop their support for certain desktop environments. I would hate to see that happen. I'm sure you all could reasure me however. :C To put it simply, GNOME being the default environment in Fedora has me sitting a little bit on the edge. Tell me there is nothing to worry about. Ha. I just don't see myself using GNOME 3.



Back in the day Fedora was always known as the bleeding edge distrobution. How true is that now today? Not that I mind bleeding egde of course. Fedora's rawhide comes to mind. Would an everyday user like you and I use it? Does it ever release? Is it anything close to rolling? Again, I'm sure I could look this up but just for the sake of conversation.



Compared to aptitude and apt I'm actually enjoying using yum. The ability to downgrade a package without jumping above and beyond?! This is good stuff. One question comes to mind. The commands 'yum remove package-foo' and 'yum erase package-foo'. Is there a difference? Coming from Debian this looks very similar to the remove and purge commands. What does the avaerage user use?



Fedora obviously releases. This is every 6 months, correct? How are users experience upgrading to release after release? I do not want to be the guy to have to reinstall every time. That would be an absolute deal breaker for me. Again, I'm sure I can be reasured although I would like honest experiences.



If anything else comes to mind I'm sure you guys will hear about it but at this point in time I can say that I like blue and fedoras are starting to grow on me. :dance:




Wine 1.4 took ~8 hours to compile from source.... is that normal?

I went out to winehq and grabbed the latest source code for the stable 1.4 release of Wine today. It took my computer roughly 8 hours to finish compiling this software. Below are my computers specs....



OS: Fedora 16

Kernel: 3.3.0-4.fc16.i686

Ram: 4gb

Processor: AMD X2 6000+



I just feel that the time it took to compile this software was somewhat outrageous. My hardware was not anything bad in my opinion so that fact that it took this long made me concerned about my machine.



Does this amount of time seem reasonable? Anyone have any ideas what may be causing the slowness on my machine? I am open to all ideas and responses.



Thanks everyone!
