[arch-general] ikev2 strongswan client on Arch
by Fulcrum 17 Mar '16

17 Mar '16

Hi I have successfully setup strongswan VPN server following instructions here[1]. I tested the server by connecting a Blackberry client and a Windows Phone client. Both used IKEv2 and worked fine. I have another laptop, running Arch, that I want to connect to the VPN server. But I can't figure how to configure strongswan as client. The link [1] doesn't describe it. Neither could I find such information from google. Regards, [1] https://wiki.archlinux.org/index.php/StrongSwan

[arch-general] System freeze when powering down.
by r.kintzi+arch-general＠pobox.net.pl 17 Mar '16

17 Mar '16

Hi there, The hardware is Asus K501UX running linux-4.5.0-mainline from aur and a GNOME desktop. The problem is the system freeze when it is powering down (not always but very often). See attached files for logs from properly (power-down-ok-tail.log) and improperly (power-down-fail-tail.log) finished power down sequences. Any clues what should/could I do to fix the issue? Let me know if more information is needed. R.

hello, I followed https://wiki.archlinux.org/index.php/Asus_x205ta from start to #Install_Arch and i'm now stuck: I'm booting on a menu with 3 choices: * Arch iso install * EFI v1 * EFI v2 none of them is working: if i select one, the screen turns black 'til i reboot. i don't even know how to get an error message or any other clue. can someone help? also: as i think some people made it, some iso of working usb keys are existing somewhere in the word. why not share those? regards -- Marc Chantreux (eiro on github and freenode) http://eiro.github.com/ http://eiro.github.com/atom.xml "Don't believe everything you read on the Internet" -- Abraham Lincoln

[arch-general] Win 10 Dual boot nightmare
by Zachary Kline 16 Mar '16

16 Mar '16

Hi All, I’ve been a Linux user off and on for ten years or so, and over the past while really come to enjoy the simplicity of Arch. I decided to install on my new HP laptop which came pre-installed with Windows 10. I honestly almost feel like I preferred the BIOS/boot sector situation. I understand the advantages of EFI in theory, but Win 10 is driving me nuts with its refusal to be a good EFI citizen. Compounding the frustration is the fact that I’m totally blind, and thus my ability to interact with EFI is limited. I’ve tried the wiki-recommended approach of using BCDEdit to set the {fwbootmgr} DEFAULT entry to the Linux boot manager, in my case systemd-boot. As far as I can tell it does absolutely nothing, that is, Windows still boots after a computer restart. The only way I’ve managed to boot Linux is to change BootNext, or as BCDEdit calls it, BootSequence. This works for a one-time boot but is fairly tedious. The alternative wiki approach of changing the path of {bootmgr}, doesn’t seem to do anything either. Windows still boots as it always has. I note that {fwbootmgr} and {bootmgr} seem to be different. I’ve considered changing the path of {fwbootmgr} instead, but ben reluctant for fear of locking myself out of Windows. Any advice would be appreciated. If this were a BIOS system I would have no trouble with Grub. Thanks much, Zack.

[arch-general] Installing php 7 and php56 at the same time?
by David C. Rankin 15 Mar '16

15 Mar '16

All, I need to downgrade php from 7 to 5.6. I built the 5.6.19 package from AUR and I'm now at the install stage. Before I do I thought I would ask if I need to remove php7 before installing php5.6? The PKGBUILD has no 'conflicts' or 'replaces' specified and they are prefixed differently (e.g. php and php56), but what I am unclear on is how my applications will know which one to use? This was necessitate when php7 broke part of my groupware package (webdav/caldav/carddav) that I need working until those can be upgraded. Do I just install php56 along side php7 or remove php7 first? If removed, then I set IgnorePkg in packman.conf -- David C. Rankin, J.D.,P.E.

[arch-general] Turning off the screen for privacy
by Zachary Kline 15 Mar '16

15 Mar '16

Hi All, One of the perks of being blind is that I don’t need the screen to work. I prefer to keep it off for privacy whenever possible. On earlier hardware, I used to be able to use the vbetool command to turn off the screen. Nowadays that seems no longer to work, “vbetool dpms off,” returns “illegal instruction.” I was wondering if anybody knew of a way too do this under current versions of Arch? Ideally, I could turn off the screen for both virtual consoles and X sessions, whenever i get around to installing Gnome. I realize this is a bit of an unusual request. Sadly, my laptop doesn’t have any easily identified hardware buttons to do this sort of thing. Thanks for any tips, Zack.

[arch-general] A new approach to verify changes in the Linux kernel ABI
by Ponomarenko Andrey 14 Mar '16

14 Mar '16

Hello, I've released new versions of the abi-compliance-checker and abi-dumper tools that are now able to easily verify compatibility of changes in the Linux kernel ABI: https://github.com/lvc/ 1. The kernel should be compiled with CONFIG_DEBUG_INFO=y and CONFIG_DEBUG_INFO_REDUCED=n additional options. 2. Create ABI dump for vmlinux: abi-dumper vmlinux -vnum 4.4.5 -kernel-export -o ABI.dump (warning: may take about 5Gb of RAM and about half an hour to analyze debug info on a powerful computer) 3. Compare ABI dumps to produce report: abi-compliance-checker -l kernel -bin -old ABI-0.dump -new ABI-1.dump The new -kernel-export option of the abi-dumper is introduced to dump only public exported symbols of the kernel, i.e. declared in the ksymtab/ksymtab_gpl binary sections + system calls. I've applied this approach on the recent releases of the Linux kernel (2.6.36-4.4.5) as an example and prepared the compatibility table here: http://abi-laboratory.pro/tracker/timeline/linux/ The distribution specific changes in the kernel can be verified in the same way to prevent/minimize ABI differences with upstream or between sequential releases. Thank you.
