Re: [gentoo-user] [SOLVED] PYTHON_TARGET errors
Hi, everything works again after syncing the portage tree today -- without the need to modify anything. So probably something was messed up upstream.

Can't I just enable some default settings somewhere? I don't want to introduce dozens of local settings for packages, especially as everything used to work before. Ralf

[gentoo-user] PYTHON_TARGET errors
Hi, so I just emerged some unrelated packages, and then the following happened when trying to update my system: !!! The ebuild selected to satisfy ">=app-editors/gedit-3.22.0" has unmet requirements. - app-editors/gedit-3.22.0::gentoo USE="introspection python spell -test -vala" ABI_X86="64" PYTHON_SINGLE_TARGET="-python3_4 -python3_5" PYTHON_TARGETS="python3_4 -python3_5" The following REQUIRED_USE flag constraints are unsatisfied: python? ( exactly-one-of ( python_single_target_python3_4 python_single_target_python3_5 ) ) The above constraints are a subset of the following complete expression: python? ( introspection exactly-one-of ( python_single_target_python3_4 python_single_target_python3_5 ) python_single_target_python3_4? ( python_targets_python3_4 ) python_single_target_python3_5? ( python_targets_python3_5 ) ) So somehow PYTHON_TARGET and PYTHON_SINGLETARGET got screwed on my system. I know how I could fix this for gedit only, but then other packages begin complaining about the same issue as well. Anything helps! Cheers Ralf

Interesting idea, but I never tried it. The gitlab .deb is pretty huge (~350MiB) and is shipped along with its own webserver, ruby and all that other dependency monsters and a minimum requirement to external dependencies. So maybe this is in deed worth a try! Good point. But what I know for sure that the .deb said to fit to current debian, where i have kind of a 'guarantee' that it will work in future with minimum pain.

Nginx on that Gentoo that serves some lightweight sites and webapps (wordpress, roundcube, usual suspects). Nginx also terminates SSL. I did not want to install gitlab on gentoo because of its tons of dependencies. So I run a Debian LXC Container inside Gentoo. Nginx then reverse-proxies and SSL-terminates the Gitlab LXC container and iptables forwards the ssh port of the gitlab container.

But from a maintenance point of view this can become a full-time job very quickly, as gitlab has pretty short innovation and release cycles.

[gentoo-user] Gentoo Stage4 for NVidias Jetson TK1
Hi, just a short announce: i built a Gentoo bleeding-edge stage4-like ready-to-boot RootFS Image for NVidias Jetson TK1. If you're interested in running Gentoo on a Jetson, you can find it here [1]. I'm trying to keep it up to date. Currently, it includes: - ACCEPT_KEYWORDS="~arm" (yeeha) - Systemd (but you should be able to use openrc as well) - Gentoo base installation with CFLAGS optimized for the TK1 - basic tools (vim, git, gcc, screen, ssh, ...) - DHCP client / SSHD enabled on boot - Latest (unpatched) mainline kernel 4.6.0-rc6 - Precompiled U-Boot Bootloader images - Precompiled Kernel + Device Trees as well as raw .configs - Root is allowed to password login to ssh: root:gentoo There's also a short article on how it was built [2].

Re: [gentoo-user] Help installing skype
Hi, I hate those tons of abi_x86_32 packages as well. This is also not solving your slot conflict, but why not: - Use a Windows VM for Skype - Use a small Linux VM for Skype (e.g. Debian) and just redirect your webcam. In this way, you don't mess up your system with 32 bit libraries. And, of course, you don't know what skype is internally doing as it is proprietary software and not famous for no bugs/vulnerabilities.

[gentoo-user] ZFS Filesystem for Gentoo Fileserver
Hi folks, I'm currently rethinking the filesystem structure of my file server. My current setup is as follows: DM Raid 10 (4x3TiB) -> Luks -> Ext4 At the moment the Raid 10 costs 50% of available memory, in future, I'd like to use Raid5 which would only costs 25% in my case. But more important: I'd also like to use ZFS on linux as I experienced it to be rock solid on Linux. (Had really good experience with ZFS together with Proxmox, damn, ZFS really rocks!). But the problem's in the details: Encryption... In my opinion, encryption is not optional, it is mandatory. Afaik, ZFS has its own encryption mechanisms which are currently not supported on Linux. So what would be the best way to go? First solution: DM-Raid -> Luks -> ZFS Pro: Known to work Con: ZFS actually comes with it's own (probably more efficient) Raid system called RaidZ which will not be used in this setup Second solution: 4xLuks -> ZFS Pro: Now it's possible to use RaidZ Con: 4x independent crypto which is a performance killer (especially as my box doesn't suport AES-NI...) Other solutions, like using EncFS is inconvenient as zfs features like file history would not work any longer. Any suggestions? Does anyone already have an encrypted ZFS setup on Linux and would like to share experience? If blocks on my physical disk fail or are corrupted, would these errors be propagated through block layers DM Raid and Luks upwards to ZFS so that resilvering will work? Cheers Ralf

[gentoo-user] Fileserver with Raid + Crypto + BtrFS
Hi, at the moment i'm running a gentoo box as fileserver, the setup is as follows: --- | Ext4| --- ^ | --- | LUKS| --- ^ | --- |MD Raid 10 | --- ^ ^ ^ ^ | | | | - - - - | hd0 | | hd1 | | hd2 | | hd3 | - - - - Besides other features, I'd like to have a snapshot functionality, and I don't want to introduce an additional layer by using LVM. So I'm thinking about to migrate to Btrfs. Btrfs supports Raid10 but no block-crypto. If I would use a HD->MD Raid->Luks->Btrfs stack, I don't benefit from the Raid implementation of Btrfs. If I would use a HD->Luks->Btrfs stack, then I would have to use four different LUKS devices, which results in four individual encryptions (and I don't have AES-NI, so this would be a tremendous slowdown). What would be the best way to have a Raid 10 together with a encrypted Btrfs? -- Besides that I would have to live-migrate the Raid10 as I don't have any spare hdd to cache the data. So I would have to degrade my Raid10. Is it possible to create a degraded Btrfs? Please don't tell me that this is insanely dangerous, I know it is ;-) Cheers Ralf
[gentoo-user] AC WiFi Card
Hi folks, I want to get rid of my old Wifi AP. As I already have a gentoo server in my flat, I'd also like to use a Wifi AP using hostapd. And, of course, I'd like to use the latest AC standard, as my laptop supports it. Additionally, I'd also like to use good old 2.4GhZ as fall-back. So I was looking for some PCI-E Wifi Card, that supports AC standard. I was thinking about sth. like this [1]. A friend of mine told me, that I should take care when buying AC hardware, as there is rare kernel support. Does anyone of you successfully use AC hardware in AP mode, Dual stack (5GhZ / 2.4GhZ)? What kind of hardware would you recommend (and is known to work without any painful hacks)? Cheers Ralf [1] http://www.tp-link.de/products/details/?categoryid=3212=Archer+T9E

Well yes, I would say so. My Box doesn't have AES-NI instruction set and it 'only' has to relatively slow cores. 4x independent Luks results in 4x independent (en|de)cryption. Even now, in my current configuration AES slows everything extremely down. (before setting up my disks a few years ago, i benchmarked the setup with and without luks. Afair, without Luks I had about Read:80Mib/s, with Luks it's about 50MiB/s, and yes, everything is aligned correctly) > >> What would be the best way to have a Raid 10 together with a encrypted >> Btrfs? > What about crypto on top of btrfs using a stacked filesystem like > ecryptfs? Nope, I also thought about that, but this is not elegant. Besides that, it would also slow down the system as ecryptfs runs in the VFS layer and is yet another layer which operates on top of an existing filesystem. (and not like luks, which would run a layer below btrfs). So that's a lot of overhead. Ecryptfs is really nice for encrypting dedicated files or directories but I don't think that it is a good solution for encrypting a _whole_ general purpose filesystem. And thinking about btrfs snapshot feature, using some 'btrfs history tool', i would probably only be able to see a lot of crypto garbage when going through my history (which can for sure be accessed by ecryptfs, but not by standard btrfs tools).

[gentoo-user] crossdev issues
Hi, I have some issues building an armv7a toolchain using crossdev. After successfully building binutils (2.25.1-r1) using: crossdev -S -v -t armv7a-hardfloat-linux-gnueabi -s0 I always end up with: # which armv7a-hardfloat-linux-gnueabi-as /usr/bin/armv7a-hardfloat-linux-gnueabi-as # armv7a-hardfloat-linux-gnueabi-as Assembler messages: Fatal error: selected target format 'elf32-littlearm' unknown This is also why crossdev fails when building the C compiler. Same happens if I try to build older binutils versions. What am I doing wrong? Is it a crossdev bug? Anything helps! Thanks Ralf
Re: [gentoo-user] Gentoo on a Lenovo X1 Carbon (3rd gen)
Well, I don't know if all of those modules are really necessary, I just activated them as Arch used to load them. But you are right, it' probably the ACPI_WMI one. No, of course I don't use the TPM stuff. Maybe I'll try to successively deactivate unneeded modules and see at which point it fails. But I don't have enough time for playing atm - it works :-) And then when it's sure I'll write it down on some wiki.

Re: [gentoo-user] Gentoo on a Lenovo X1 Carbon (3rd gen)
Uhm - why should it do so? And why should it do so if the module is NOT available? In deed, I do have full disc encryption, but the key stays inside RAM if the machine goes to standby.Furthermore, I did not configure TPM (yet). Maybe the TPM Chip (if enabled by the bios) needs some Reinitialization (even if the TPM is not configured and used) after a wakeup and refuses wakind up if this reinitialization does not take place. For me, this would sound more reasonable why my machine only wakes up when TCG_TIS is enabled.

Are you sure that the necessary modules are definitely put into the initrd and that the kernel will be able to load them soon enough at boot time? I double checked it and now I am sure: For reasons of comfortability I inspected a standard Arch-Linux installation. It supports rootfs encryption and xts is loaded in the initrd as module. So it is possible to treat it as a module. Besides that: Why should your kernel config allow you to compile it as module if it isn't useable as module? Compiling those modules into the kernel is definitely more secure (in terms of being sure that they are always available) and doesn't do any harm, because they need to be loaded anyway. Yes for a homebrew kernel, i can second that. Btw., several dm-crypt/LUKS documentation (all that I've read) say that those modules have to be compiled into the kernel directly. After loading the modules you can see that they are available by cat /proc/crypto. You won't be able to run this command when the kernel tries to unlock the LUKS container at boot time. No, but it is accessible when creating your LUKS volume, and that's Marko problem at the moment. The modules can be loaded _after_ bootup as well. If you want to unlock the LUKS container at boot time (particularly if your root partition is encrypted), loading the modules after bootup is too late. Loading those modules during the early bootup phase in your initrd is actually not too late. Ah, and for completeness sake: Grub2 is able to speak LUKS. So your kernel and initrd maybe inside an encrypted volume. So I wouldn't risk it. Neither do I. Cheers Ralf

Re: [gentoo-user] RTL8192CU
Hi, I had a rtl8192ce in my laptop. Nothing but problems with Linux. Don't know why, but the signal strength always was much better when using Windows. For me, the rtl8192ce only worked when using it as a module, not hard compiled in the kernel. Second, it is important to know that this WiFi Card stopped working for me with kernels 3.17. The card was detected but it didn't show up any WiFis. I read that there were fundamental changes to the rtlwifi stack in 3.18. Eventually I decided to buy a new card and better card (Intel Centrino, I now can connect to 5GhZ networks :) ) for my laptop and I'm so happy now :) No more Realtek WiFi cards for me.

Re: [gentoo-user] OT Best way to compress files with digits
Well, you could just save the generating algorithm. *scnr* I think compressing pi is hardly possible, as the numbers are distributed pretty randomly. But why do you want to compress? You can't work on compressed data. And there are enough sites on the internet, where you can get your digits again. Pi is not supposed to change over the years :-) Cheers Ralf On 31.10.2014 17:36, meino.cra...@gmx.de wrote: Hi, I have a lot of files with digits of PI. The digits are the characters of 0-9.

With what practical way of compression is it possible to compress the files (file by file) as much as possible? Thank you very much in advance for any help! Best regards, mcc
[gentoo-user] Problem with power management of SATA hard drives
Hi there, I'm using Gentoo ~amd64 on my NAS. This is my setup: Mainboard - Asus E35M1 CPU - AMD E350 HDD - 1x 500GiB WD Caviar Green WD5000AADS (root) HDD - 4x 3TiB WD Caviar Green WD30EZRX (Raid10) As these hard drives are desktop hard drives and not designed for 24/7 purposes, I want to spin them down when they are not in use. (And in fact, they will probably be idling most of the time, so let's save energy) I'm able to force spin down those drive by using hdparm -y. hdparm -C then tells me, that they switched from active/idle to standby. Setting standby-time using hdparm -S also seems to work fine: hdparm -S 10 /dev/sdb /dev/sdb: setting standby to 10 (50 seconds) But this does not standby my drive after 50 seconds. So I tried to set the Power Management Level: hdparm -B 5 /dev/sdb /dev/sdb: setting Advanced Power Management level to 0x05 (5) HDIO_DRIVE_CMD failed: Input/output error APM_level = not supported Obviously, my system does not support APM what I can hardly believe... So I tried to enable APM but my kernel configuration doesn't allow me to enable APM support as long as I use a 64 bit kernel - APM option is only available for 32 bit kernels. What am I doing wrong? My hardware is *relatively* new and I don't believe that it doesn't support those power management features. But besides that, does anyone have further tips or tricks to protect hard drives? E.g. try to minimize Load Cycle Count, ... Output of hdparm -I: http://pastebin.com/RyAU6u8T Cheers, Ralf

I found distcc hard work when I was installing Gentoo on my Atom box, so I NFS-exported its package directory to a 32-bit chroot on my workstation, did all the emerging etc. there, including building binary packages, then emerge -k on the Atom installed the system with minimum fuss.

Hi, On 04/11/2014 12:55 AM, walt wrote: Steve Gibson explained that the heartbeat feature was introduced in openssl to allow *UDP* connections to mimic the 'keepalive' function of the TCP protocol. IIRC Steve didn't explain how UDP bugs can compromise TCP connections. Anyone here really understand the underlying principles? If so, please explain! yes, a TCP connection is stateful, so imho heartbeat is not necessary. But you don't always speak UDP or TCP. Imagine some sort of direct connection without any type of transportation layer. As a generic cryptographic library, OpenSSL is designed to be adaptable and universal. That broke OpenSSL's neck. We only can hope, that the heartbeat exploit was not widely used before they published that zero-day. But we can be sure, that this is not going to be the last vulnerability of this kind.

[gentoo-user] How to properly set up Bluetooth
Hi, i'm trying to set up a simple bluetooth keyboard, but somehow it won't work :-) This is my setup: Systemd + GDM + Fluxbox (this is the easiest way for me to use gnome-stuff like gnome-keyring-daemon, ... In the background my fluxbox is also running a gnome-settings-daemon) hcitool dev successfully detects my bluetooth device. According to [1] I tried to set up my keyboard using the command line. But actually simple-agent doesn't seem to be available in bluez 5.x. So I tried to use blueman-applet. This is a snippet of the output of blueman-applet: Function on_manager_state_changed on RecentConns Failed Traceback (most recent call last): File /usr/lib64/python2.7/site-packages/blueman/main/PluginManager.py, line 220, in Run ret = getattr(inst, function)(*args, **kwargs) File /usr/lib64/python2.7/site-packages/blueman/plugins/applet/RecentConns.py, line 195, in on_manager_state_changed adapters = self.Applet.Manager.ListAdapters() File /usr/lib64/python2.7/site-packages/blueman/bluez/utils.py, line 28, in warp raise errors.parse_dbus_error(exception) DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method ListAdapters with signature on interface org.bluez.Manager doesn't exist It seems to me that this is a dbus problem or something like that, but I don't know what I am doing wrong.

Re: [gentoo-user] emerge -uD @system with lots of blocks!
What I try to do in such cases (I know this is not the best solution, but it always works quite good) is to uninstall all packages that cause problems. After the world update, you can reinstall those. In your case, i would try to uninstall - libreoffice - qt* - all blocking packages But this might be very risky! Another try could be to install bunch of packages by hand. E.g. Try to update python, if this works try to update let's say systemd, and so on. Oh, I see your gentoo actually wants to install systemd? Did you change to gnome3? Which profile do you use?

Re: [gentoo-user] How to prevent Firefox from switching VT?

Re: [gentoo-user] Does this qualify as some bug ?
While trying to prevent 'net-dns/pdnsd' to listen on TCP and on to avoid TCP queries, I changed 'tcp_server' parameter to 'off' and 'query_method' parameter to 'udp_only' in /etc/pdnsd/pdnsd.conf . But when I restarted pdnsd I found it is still listening on TCP. I checked /etc/conf.d/pdnsd and found no option related to listening to 'TCP' set. So, then I checked /etc/init.d/pdnsd and I found that 'pdnsd' has been launched with '-t' command line argument (enables the TCP server thread. pdnsd will then serve TCP and UDP queries.) . So to disable, I need to append '--notcp' to PDNSDCONFIG in /etc/conf.d/pdnsd. So I think, listening shouldn't be made by default, even if it is, then it should be in configuration file, not in init.d script . Since noone answered, I'll try. I'm not into the details of your problem but I have the impression your suggestion should be stated to the pdnsd developing community, not on gentoo. I'd qualify it as bug, but YMMV, and again, I don't know much about it. ralf -- [EMAIL PROTECTED] mailing list
