UPnP vs. Fedora 14 firewall
by Mike Wohlgemuth 02 May '11

02 May '11

I have several different services on my network that use UPnP, and none of them seem to work unless I disable the Firewall on my Fedora 14 desktops/laptops. Everything I've read says that I should be able to allow UDP on port 1900, but that doesn't seem to help. Can anyone tell me or point me to documentation about what I need to enable to let my Fedora 14 machines to see the services via UPnP? Thanks Mike

xrandr not working
by Suvayu Ali 02 May '11

Hi Fedora users, On my laptop this used to work before: $ xrandr --output LVDS1 --mode 1280x800 --output VGA1 --mode 1680x1050 --above But today it stopped working. Following is the output from xrandr on my system. Any thoughts what is going wrong? $ xrandr Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192 LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm 1280x800 60.0*+ 50.1 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 433mm x 271mm 1680x1050 60.0*+ 1280x1024 75.0 60.0 1440x900 59.9 1280x960 60.0 1152x864 75.0 1152x720 60.0 1024x768 75.1 60.0 832x624 74.6 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) -- Suvayu Open source is the future.

Top Gnome panel problems.
by Aaron Konstam 02 May '11

02 May '11

After I restored the Gnome top panel using Main Menu application I am left with some problems. 1. I can't restore the default volume control icon that appears on installation. 2. I can't restore the networkmanager applet (containing vertical bars when using wireless) that is there on installation of the F14 version. Wireless still works but how can I restore these icons? -- ======================================================================= Showing up is 80% of life. -- Woody Allen ======================================================================= Aaron Konstam telephone: (210) 656-0355 e-mail: akonstam(a)sbcglobal.net

My memory is a bit sketchy but along with IGD I had to add a few firewall rules and a route to allow multicast upnp. This was for a fedora box that I was using as a firewall/gateway system. Some igd docs. http://linux-igd.sourceforge.net/documentation.php Below is a script I used for the firewall rules. [agagne@linux0 tmp]$ cat bin/add-upnpd.sh #iptables -N UPNP #iptables -I FORWARD 2 -j UPNP #iptables -A INPUT -i eth1 -p tcp --dport 2869 -j ACCEPT #iptables -A INPUT -i eth1 -p udp --dport 1900 -j ACCEPT # Good firewalls drop everything that has not been explicitly allowed, # so first create rules to allow other computers to connect to the upnp daemon. iptables -t filter -A INPUT -i eth1 -d 239.0.0.0/8 -j ACCEPT iptables -t filter -A INPUT -i eth1 -p tcp --dport 49152 -j ACCEPT iptables -t filter -A INPUT -i eth1 -p udp --dport 1900 -j ACCEPT # Create chains for the rules to be created by the upnp daemon. iptables -t filter -N UPNP_FORWARD iptables -t filter -I FORWARD 2 -j UPNP_FORWARD iptables -t nat -N UPNP_PREROUTING iptables -t nat -A PREROUTING -j UPNP_PREROUTING Use at your on risk as I am not a firewall expert. I got this working after much googleing on how to set-up igd so my son could play games from another system runnning win7. Alan

Where did gdm-{restart,stop} go?
by Richard Shaw 02 May '11

02 May '11

Ok, on my MythTV box I would occasionally get freezes where Ctl-Alt-Backspace would not work, or I'd get a call from the wife and need to restart X remotely from work. On Fedora 10 I found a handy command, gdm-restart which worked quite nicely. After upgrading to F12 it was gone, then I found gdm-stop which seemed to do the same thing. Now that I'm on F14, neither command is available and I haven't found a suitable replacement. Of course init 3 && init 5 will get the job done but it causes unnecessary stop and starting of services. Thanks, Richard

Gnome Shell not working after PreUpgrade
by Stewart Williams 02 May '11

02 May '11

Hi All, I have just done my first PreUpgrade from F12 to F14. The upgrade was successful apart from gnome-shell no longer works, which I was happily using on F12. I get this error: (mutter:2804): mutter-WARNING **: Could not load library [/usr/lib64/mutter/plugins/libgnome-shell.so (/usr/lib64/libgtk-x11-3.0.so.0: undefined symbol: g_application_add_action)] $ rpm -qa kernel mutter compiz kmod-nvidia gnome-shell gnome-shell-2.31.5-7.fc14.x86_64 kmod-nvidia-260.19.36-1.fc14.3.x86_64 mutter-2.31.5-3.fc14.x86_64 compiz-0.8.6-6.fc14.x86_64 kernel-2.6.35.12-90.fc14.x86_64 Compiz and mutter (on it's own) work fine and the binary nvidia driver is loading OK. Does anyone have any idea's or should I file in Bugzilla?

Hello, I wish to link several .o files to make only one .o file not executable (it will relinked later). I would like to first make a prelinked file easier to then link them to the excutable file (ie. with a main).

serial port paths for Vbox/XP for GPSs
by Beartooth 01 May '11

01 May '11

I'm in process of installing XP under VirtualBox on Fedora 14 Linux, after which I'll install MapSource, TopoUS2008, and others under XP, hoping to be able to get my Etrexes and Rinos to talk to the software. I do have a physical serial port on the machine; but I don't see what path to set Com1 and Com2 to. Anyone know? -- Beartooth Staffwright, Neo-Redneck Not Quite Clueless Power User I have precious (very precious!) little idea where up is.
