Heads up: possible BASH security vulnerability
by Patrick O'Callaghan 06 Oct '14

06 Oct '14

http://arstechnica.com/security/2014/09/bug-in-bash-shell-creates-big-secur… >From the article: The vulnerability affects versions 1.14 through 4.3 of GNU Bash. [...] To check your system, from a command line, type: env x='() { :;}; echo vulnerable' bash -c "echo this is a test" If the system is vulnerable, the output will be: vulnerable this is a test An unaffected (or patched) system will output: $ env x='() { :;}; echo vulnerable' bash -c "echo this is a test" bash: warning: x: ignoring function definition attempt bash: error importing function definition for `x' this is a test I tried it and got the positive (vulnerable) result. Can we assume a patched version of Bash will be released shortly? poc

Wrong Screen Resolution after uninstalling nvidia packages from rpmfusion
by JD 03 Oct '14

03 Oct '14

My physical screenis 1280x800. It is the screen of a Dell Latitude E6500 laptop. Now, all gui app windows are being displayed as if my physical screen is 1280x760, and the app's window is 1280x800, thus I can pan the window up and down by moving the mouse to top of screen or bottom of screen. This resizing happened AFTER I uninstalled the rpmfusion nvidia packages: xorg-x11-drv-nvidia.x86_64 xorg-x11-drv-nvidia-304xx.x86_64 xorg-x11-drv-nvidia-304xx-devel.x86_64 xorg-x11-drv-nvidia-304xx-libs.x86_64 xorg-x11-drv-nvidia-libs.x86_64 xrandr reports: # xrandr --verbose xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1280 x 768, maximum 1280 x 768 default connected 1280x768+0+0 (0x186) normal (normal) 0mm x 0mm Identifier: 0x181 Timestamp: 55232 Subpixel: unknown Clones: CRTC: 0 CRTCs: 0 Transform: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 filter: 1280x720 (0x182) 0.000MHz h: width 1280 start 0 end 0 total 1280 skew 0 clock 0.00KHz v: height 720 start 0 end 0 total 720 clock 0.00Hz 1024x768 (0x183) 47.972MHz h: width 1024 start 0 end 0 total 1024 skew 0 clock 46.85KHz v: height 768 start 0 end 0 total 768 clock 61.00Hz 800x600 (0x184) 29.280MHz h: width 800 start 0 end 0 total 800 skew 0 clock 36.60KHz v: height 600 start 0 end 0 total 600 clock 61.00Hz 640x480 (0x185) 18.432MHz h: width 640 start 0 end 0 total 640 skew 0 clock 28.80KHz v: height 480 start 0 end 0 total 480 clock 60.00Hz 1280x768 (0x186) 0.000MHz *current h: width 1280 start 0 end 0 total 1280 skew 0 clock 0.00KHz v: height 768 start 0 end 0 total 768 clock 0.00Hz Is there a way to restore it back to physical resolution of 1280x800?

UCB keybord curiosity
by Geoffrey Leach 01 Oct '14

01 Oct '14

I have a system that functions as a PVR, and is re-booted daily. There have been no recent updates. On yesterday's reboot (and subsequently) the kernel does not recognize A/N keystrokes from the KBD. Mousepad motions and clicks work fine. Looking at the dmesg output, there appears to be nothing amiss. When I move the USB transceiver to another system, everything works as it should. Suggestions? Thanks.

strange issue with ssh on F20 on DSL/VPN
by Ranjan Maitra 30 Sep '14

30 Sep '14

So, I have a strange issue. I have a local machine (laptop) connecting remotely to several desktops including one that is a fully updated F20 (this is the one I have total control over and therefore my choice of distributions). The others are RHEL5's or Centos6. Connections are only permitted to all machines through VPN (university policy). So, I on my new DSL connection (which is wired and will replace my cable modem connection) but currently both are active. Anyway, I can connect to all machines when I am on the cable modem (using wireless) and VPN unlimited number of times. I can connect to all the non-F20 machines using ssh unlimited times when I am on DSL and VPN. However, I can only connect once t the F20 machine when I am on DSL and the VPN. There is no way I can connect directly. (I can connect to one of the non-F20 machines by ssh and from there connect to the F20 machine however.) I can only connect directly again to the F20 machine by ssh from my local machine by rebooting the remote F20 machine. And that too for only one time. After I log out, I can not connect again. What should I looking for? /var/log/secure does not have any entry when I can not connect (however it does have an entry when I cancel the connection by Ctrl-C -- "Connection closed"). Any suggestions as to how to diagnose and solve this problem? Sorry for bringing forth the strangest of questions. I am hoping that someone more familiar with networking issues will have some idea and suggestions on what is going on. Many thanks and best wishes, Ranjan ____________________________________________________________ FREE 3D EARTH SCREENSAVER - Watch the Earth right on your desktop!

fed/centos question
by bruce 30 Sep '14

30 Sep '14

Hi. Really a reinstall question. You can have an install server for http/ftp/etc install You can also have pxe startup, as well as the base install from the dvd/network. However, I'm trying to figure out how to go about (if it's possible) to do a reinstall of a system remotely. I'd like to be able to ssh into a box, and then do a reinstall of a given system based on the different kickstarter file that I created. I'd like to ssh into the box, run a given cmd, use a given kickstart process and have the entire process just work! But I've been looking all over to try to figure out exactly how this would work or what all the issues are. Any thoughts/pointers would be helpful The target boxes would be centos6.5 (and above) as well as fed 18 and above.. Thanks guys..

Dell iDRAC access on F20
by CLOSE Dave 30 Sep '14

30 Sep '14

My iDRAC access worked fine on earlier versions of Fedora but hasn't been working for F20. I've enabled and started serial-getty@ttyS1 and insured ttyS1 is listed in /etc/securetty, but serial access usually doesn't see anything. A few times I've seen the string of garbage that is characteristic of a mismatched data rate, but sending BREAKs doesn't cause anything to appear. What am I missing? -- Dave Close

Problem with duplicate packages on system
by JD 30 Sep '14

30 Sep '14

# yum check Loaded plugins: langpacks, refresh-packagekit cogl-1.16.0-3.fc20.x86_64 is a duplicate with cogl-1.16.0-2.fc20.x86_64 flickcurl-1.26-1.fc20.x86_64 is a duplicate with flickcurl-1.25-1.fc20.x86_64 gvfs-1.18.3-3.fc20.x86_64 is a duplicate with gvfs-1.18.3-2.fc20.x86_64 libplist-1.11-2.fc20.x86_64 is a duplicate with libplist-1.10-2.fc20.x86_64 libspnav-0.2.3-1.fc20.x86_64 is a duplicate with libspnav-0.2.2-6.fc20.x86_64 openvpn-2.3.2-6.fc20.x86_64 is a duplicate with openvpn-2.3.2-4.fc20.x86_64 How can this be? I thought yum update takes care not to allow duplicates?
