I have a python script that I use to create Debian packages automatically for me. When running this under Ubuntu, it only requires the passphrase to be entered once to sign the changes and dsc files. However when running under Debian it is required to enter it every time. The script is using the debuild command to do the actual package building.
View 1 RepliesI am experimenting with LUKS+dm_crypt. My setup is something like this: a LVM VG made of multiple Physical Volumes (PV). That VG contains multiple LV (Logical Volumes), most of them encrypted via LUKS+dm_crypt (via cryptsetup).Editing "/etc/crypttab", the system will requiere a passphrase for each encrypted LV. But since all my encrypted LVs share the same passphrase, I would like to be prompted only ONCE, instead of twelve times (I have 12 encrypted LV).
I have thought about writing a script to include in initrd that ask for the password once, store the result somewhere volatile (ramdisk?), and provide that password for the rest of "/etc/crypttab" entries.But this seems complex and fragile.I wonder if there is something I am missing, or some other easier way.
I was wondering if a standard Debian 8 system with Gnome desktop does any kind of local dns caching, and if so, what the command is for clearing it. (Assuming I haven't purposely installed any DNS server software.)
I found multiple posts on the Web about unix DNS caching, but with widely different answers across distributions and across time.
how to make removable media (e.g. USB sticks) not have any write caching. I want to prevent data loss when they are removed after file copying appears done but before write caches are written. I'm using Gnome on Squeeze.
I've found suggestions of adding the 'sync' mount option to /system/storage/default_options/vfat/mount_options in the Gnome configuration. However this doesn't seem to completely eliminate write buffering, as the drive activity light continues for several seconds after file copying appears done, and unmounting drives produces a dialog box which says to wait whilst data is written to disk.
I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

I'm trying to compile Ardour on jessie amd64 using the Debian source code (there's already an ardour package but I want to use different compile options). I've applied the Debian patches and have all the required dependencies installed.
Scons quits with a KeyError message from python2.7 saying that os.environ['DEB_HOST_ARCH_OS'] is not defined.
Checking with 'dpkg-archtecture -l' shows that DEB_HOST_ARCH_OS=linux, but 'print os.environ["DEB_HOST_ARCH_OS"]' in python says that name 'os' is not defined. The scons script has 'import os' at the top so it should be seeing it.
How do I make this visible to python (I'm assuming this problem is specific to the jessie python2.7 installation and not python in general)?
I use Terminator as my terminal and in the last couple of months, I need to either run
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libfreetype.so.6 /usr/bin/terminator
or
symbolic link /usr/local/lib/libfreetype.so.6 to the above file
In order to have the application run without the error message: You need to install the python bindings for gobject, gtk and pango to run Terminator.
I have been using the symlink method for the most part, but when I run an apt upgrade, often the /usr/local/lib/libfreetype.so.6 symblink changes to point to /usr/local/lib/libfreetype.so.6.5.0 and I have to manually re-link.
I have tried reinstalling gobject, gtk and pango packages for python but nothing has worked.
I'm trying to get a python script to run on my Netgear ReadyNas NV+, but keeping running into an indentation error. The script should be using feedparser to monitor an RSS feed (like a yahoo pipe) and automatically download the .torrent files. I've checked the script, and I do not believe I am mixing spaces and tabs anywhere, but I'm still not sure why it will not run.
I've already installed python and the python feedparser (required for this script). Or, at least I believe I have the feedparser installed--I'm not sure how to verify it was installed successfully without running this script.
I'd love to know if there is something glaringly obvious that I'm missing here. Script and error message below:

There seems to be a lot of documentation automatically installed on my hard drive, is there a unified browser for all of the -doc packages? Is it just the man command?

I've googled around and don't know exactly what I'm looking for.

from the Ubuntu PPA to the Mepis 8.5 community repo, and it works a treat. It would also be installable in Debian Lenny and higher, as long as you have VLC >= 0.9.4 for the built-in player (which is backported for Lenny in another post I had here) I also ported over the nonfree sp-auth deb package which it requires, only for Intel-base 32 and 64 bit CPUs (it's a 32 bit static binary that does the actual P2P). I could roll a Lenny specific package which does not use VLC if you tell it to use an external player such a mplayer or xine; is anyone interested?
