ssh portforwarding, running test client/server over tunnel
by bruce 14 Sep '13

14 Sep '13

Hi. Trying to setup a quick test to create a ssh tunnel between A and B, and running a test nc server over the ssh connection on port 7100.. As far as I can tell, it should be a matter of setting up the port forwarding between A and B and then running the test server/client on the A and B machines.. now, the tricky part, the target "B" machine is being run on a VM, so the port isn't 22.. I used the following to setup the port forwarding: ssh -L 7100:74.142.196.218:7100 user(a)74.142.196.218 -p 50122 so being on machine A, the local machine, I setup the ssh tunnel into machine B, where B is the VM, running ssh over port 50122 this part appears to work. However, when I then run a test nc server on both machines using port 7100, I get the following: machine B: nc -l 7100 machine A nc localhost 7100 which causes the machine B to display a crash!!!! >>>channel 3: open failed: connect failed: Connection refused <<< any ideas/thoughts??? I'm ultimately looking to run a gearman server running on port X and being able to create a ssh tunnel into the server to access the port. thanks

video accel F19 on Acer Aspire One D255E netbook, lack thereof.
by Fred Smith 14 Sep '13

14 Sep '13

Hi gang! I have two netbooks, an Asus 901 eeepc, and a newer Acer Aspire One D255E. on the older Asus, GoogleEarth runs quite nicely (for such a minimally- powered system). it's clearly getting some graphical acceleration from the video chipset. (Thismachine is still running F17, soon to be upgraded, I hope.) the Acer, OTOH runs Google Earth so poorly as to be painful to watch it slowly accumulate bits on the screen, taking several minutes to build up the default image upon startup. (This machine is running F19.) The Asus is an old Atom N270 where "lsmod | grep video" reports: $ lsmod | grep video uvcvideo 71406 0 videobuf2_vmalloc 13003 1 uvcvideo videobuf2_memops 13001 1 videobuf2_vmalloc videobuf2_core 37715 1 uvcvideo videodev 97059 2 uvcvideo,videobuf2_core media 19719 2 uvcvideo,videodev video 18551 1 i915 i2c_core 28312 6 drm,i915,i2c_i801,drm_kms_helper,i2c_algo_bit,videodev the Acer (Atom N570, dual core) reports this from lsmod | grep video: acer aspire one D255E # lsmod | grep video uvcvideo 71417 0 videobuf2_vmalloc 13003 1 uvcvideo videobuf2_memops 13001 1 videobuf2_vmalloc videobuf2_core 37679 1 uvcvideo videodev 97069 2 uvcvideo,videobuf2_core media 19691 2 uvcvideo,videodev i2c_core 28434 6 drm,i915,i2c_i801,drm_kms_helper,i2c_algo_bit,videodev video 18551 2 i915,acer_wmi they appear virtually identical, except that the Acer includes "acer_wmi" along with i915 for "video". Given that they seemto use the same Intel drivers, I'd expect them to provide more or less the same video performance but at least for Google Earth, they donot. Anyone got any cles? thanks!

Weird problem if printing page ranges of pdf files in F19 by acroread/evince
by Joachim Backes 13 Sep '13

13 Sep '13

Hi all, I have the following problem with printing page ranges of pdf files to my laser printer (samsung ml-1660) using acroread or evince: Only the first page of the range is printed, the rest of pages is missing. The same happens if I try to print the whole pdf file (only page #1 is printed). No such effect if I print to a cups-pdf printer (all pages printed) Or no such effect if using the lp command together with -P option (page range): all desired pages are printed flawlessly. I have no idea since which date this happens. Any ideas are welcome. Kind regards Joachim Backes -- Fedora release 19 (Schrödinger’s Cat) Kernel-3.11.0-200.fc19.x86_64 Joachim Backes <joachim.backes(a)rhrk.uni-kl.de> https://www-user.rhrk.uni-kl.de/~backes

More on virt-viewer for windows
by Fernando Lozano 13 Sep '13

13 Sep '13

Hi there, As the newer windows binaries kindly provided by teuf won't work because of missing DLLs, I returned to the latest binaries provided by spice-space.org. remove-viewer.exe works fine, after I foud where to put TLS certificates. Not that user-friendly though. :-) virt-viewer and virsh won't connect, although they are using the same certificates as a Linux client. The short-term goal is getting virt-manager to work, butI think it'd be easier to get virsh working first, but the solution would apply to virt-manager as well. Microsoft SystemInternals ProccessMonitor shows the certificates are being found and read (that's how I found where to put then). I assume that's ok. But after that nothing I can use for troubleshooting. Looks like a bug on the windows port networking code. But I finally found how to use libvirt own debugging features. So here's attached a log for the windows machine, which can't connect, and the linux machine, which connects fine to the same kvm host, using the same certificates and the same URL (to the same CentOS 6.3 kvm host). They are using different virsh and libvirt releases, so I added to the logs the output of "virsh -V". Both machines are on the same level-2 network, vlan and IP subnet. I hope this helps someone find the bug and provide me with new binaries to test. :-) If someone helps me getting the missing DLLs for teuf newer binaries, I can generate a log using them. It looks the missing DLLs is another bug per se. Of course, I hope someonte at Red Hat realizes a missing or broken windows ports hurts KVM and RHEL and RHEV market share and put more people on it. :-) PS: Someone offered helping me compiling the windows port. I'll give it a try, no promises, free time is very scarse. :-( []s, Fernando Lozano

serial console
by lxnf98mm＠gmail.com 13 Sep '13

13 Sep '13

I have a server set up with Fedora 18, works ok. I decided to make the root partition encrypted, set that up, works ok. The machine is remote so I use a serial console to connect, works ok. Here's the rub, while booting there is a pause to request the passphrase to unlock the encrypted fs. If I have grub configured to display boot messages on tty0 and ttyS0 the passphrase can only be entered at tty0. If I configure grub to only display boot messages on ttyS0 then the passphrase can be entered on ttyS0. How can I display boot messages on tty0 and ttyS0 and enter the passphrase on the terminal that I am working on. This is my /etc/default/grub. GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_SAVEDEFAULT=true GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,57600n8 ipv6.disable=1 selinux=0 " GRUB_TERMINAL="console serial" GRUB_SERIAL_COMMAND="serial --speed=57600 --unit=0 --word=8 --parity=no --stop=1" GRUB_DISABLE_RECOVERY="true" Richard

Does anybody know why Fedora does this?

We all know, I hope, that cd is a built-in function of whatever shell you're using. [joe@khorlia ~]$ cat /usr/bin/cd #!/bin/sh builtin cd "$@" [joe@khorlia ~]$ Does anybody know why this file exists?

current way to show pop-up windows in other users sessions?
by M. Fioretti 12 Sep '13

12 Sep '13

Greetings, it's been a looong, long time since the last time I did this, so I need a bit of help to refresh my memory. In a sense, what I'm unable to remember right now is what docs I should read... I have a cron shell script that, if some event happens, must: 1) check if a *local* user A is currently logged in, and in which session/display 2) if yes, pop up a window in the session of user A, showing the content of a text file I know how to do (1) with "who": [marco@polaris ~]$ who bill :2 2013-09-10 19:56 this tells me that "bill" (i.e. NOT me, another user!!!) **is** currently logged in on display :0 and I also know how to do (2) with kdialog, zenity, xmessage... but of course, if I launch kdialog I get nothing but the "Error: can't open display" message. Setting DISPLAY to ":2", "ip.address:2", ":2.0"... doesn't change anything. (many) years ago this was solved with xhost +, but not now. So, what is the current way to make (2) happen? Possibly one that is distribution-agnostic? TIA, Marco

How do I configure this network adapter? Thanks in advance, Best regards, Giovanni
