Well, I am glad I was not the only one affected by this. I wish there were at least an option to decide which characters get displayed.

Just to make it clear, to avoid any misunderstanding. You need the kernel source code to compile the modules. This is not only a requirement when building kernel modules. The linux packages are just split into the kernel image and header packages, while other packages usually aren't split and contain their header files.

You're right, that could be unfair esp when you install kernels via aur. Is it possible to add a hint while installing the package? I know theres already an opt dep but for me an opt dep is very optional but in this case you really need some headers to get the modules working. Cheers Chris
[arch-general] Wifi disconnects every few minutes
Hi everybody,
I have an Alfa AWUS036H USB Wifi adapter (Ralink Technology, Corp.
RT2870/RT3070 Wireless Adapter). It's using rt2800usb driver. I use
netctl to connect to wifi.Here is my netctl profile:
Description='Mine'
Interface=wlp0s18f2u4
Connection=wireless
Security=none
ESSID=ncepu-student
IP=static
Address='10.110.7.7/24'
Gateway='10.110.7.254'
DNS=("8.8.8.8";"8.8.4.4")
The problem is that 'ip addr show' says that I'm still connected to my
wifi AP. I can see my IP and everything but I can't access internet. I
can't even ping google or any other server. When I try to curl a local
LAN web server, it says 'there is no route to xxx.xxx.xxx.xxx', where
xxx.xxx.xxx.xxx is my local router. So I have to disconnect and
reconnect every few minutes to use internet.
Here are ping results to a local server (while still connected to wifi,
as per 'ip addr'):
PING yyy.yyy.yyy.yyy (yyy.yyy.yyy.yyy) 56(84) bytes of data.
From 10.110.7.7 icmp_seq=1 Destination Host Unreachable
From 10.110.7.7 icmp_seq=2 Destination Host Unreachable
From 10.110.7.7 icmp_seq=3 Destination Host Unreachable
From 10.110.7.7 icmp_seq=4 Destination Host Unreachable
From 10.110.7.7 icmp_seq=5 Destination Host Unreachable
From 10.110.7.7 icmp_seq=6 Destination Host Unreachable
^C
--- yyy,yyy.yyy.yyy ping statistics ---
6 packets transmitted, 0 received, +6 errors, 100% packet loss, time 5008ms
Where yyy.yyy.yyy.yyy is a server that is always available to all PCs
connected to local LAN or wifi.
I read somewhere that netctl and dhcp don't work well together so I
changed DHCP to static IP*. I even tried changing the wifi access points
(There are multiple APs around me). In all cases, I am able to connect
to the AP and use internet, but only for a few minutes.
For debugging, I removed the usb cable, and reattached the wifi
adapter.Here are some entries from dmesg showing the plugging in of the
adapter and subsequent connection trials. Note that I disconnected and
reconnected the AP around [21713.142829].

I hope someone here can help me find a solution to this incredibly

*With DHCP, I got disconnected from the wifi AP with 'journalctl'
showing some errors about 'carrier lost'. With 'static IP', I don't get
disconnected but can't access internet either.

Hi, you miss that the official provided linux and linux-lts headers are already optional dependencies [rocketmouse@archlinux ~]$ pacman -Qi virtualbox-host-dkms | grep -A1 Optional\ D Optional Deps : linux-headers [installed] linux-lts-headers and an example from one of my bash histories [root@archlinux rocketmouse]# grep dkms ~/.bash_history | grep 5 dkms remove -m vboxhost -v 5.0.12 --all dkms install vboxhost/5.0.14 -k 4.3.3-3-ARCH/x86_64 && dkms install vboxhost/5.0.14 -k 4.0.4-rt1-1-rt/x86_64 && dkms install vboxhost/5.0.14 -k 3.10.61-rt65-1-rt-lts/x66_64 as you can see, a kernel not necessarily is provided by official repositories so you can not make such headers hard dependencies and I not necessarily have linux or linux-lts from official repositories installed at all, so I also don't want to be forced to install the headers.

I guess what you are missing is that it is already an optdepends. It would be rather unfair towards users of a different kernel to make a hard dependency on the main kernel. -- Eli Schwartz

Performance-wise, it doesn't really matter if a few additional lines need to be parsed.
[arch-general] Missing Dependency virtualbox-host-dkms
Cheers Replacing the `virtualbox-host-modules' with the `virtualbox-host-dkms' package causes a "modprobe: FATAL: Module vboxdrv not found in directory /lib/modules/4.4.3-1-ARCH". The whole misc (/lib/modules/4.4.3-1-ARCH/kernel/misc/) directory is missing. You need to install the `linux-headers' package for a working dkms. DKMS than can make the modules and creates the misc folder with all virtualbox *ko files. Is it possible to add the `linux-headers' package as a dependency for the `virtualbox-host-dkms' package or miss I something? Thanks Kind regards Chris

Hello Andre, According to what you need, you may want to use the 'free' command instead, as its output is much simpler than the output of the /proc/meminfo file E.g. >$ free > totalused freeshared buff/cache available >Mem: 5951844 486324 4969788 75812 495732 5339492 >Swap: 00 0 or, if you prefer it be displayed in mebibytes, >$ free -m > total usedfreeshared buff/cache available >Mem: 5812496 483273 484 5193 >Swap: 0 0 0 you can also check the man page for more display options Hope this helps, Jonathan
[arch-general] most efficient way to get linux kernel statistics
hello archers, thought i ask here first, before i try some kernel mailing list. i'm writing (for fun) a tiny daemon that sends linux usage (cpu, mem, net, etc.) statistics as efficiently as possible to another machine, repeatedly, to get "live" data. at the moment i'm simply sending /proc files, but they sometimes have too much data. so was wondering if there is a more efficient way to get (only parts of) the data thats available in /proc? for example, /proc/meminfo has all this info: MemTotal:8051660 kB MemFree: 6046020 kB MemAvailable:6843080 kB Buffers: 109116 kB Cached: 708336 kB SwapCached:0 kB Active: 1332416 kB Inactive: 455428 kB Active(anon): 971040 kB Inactive(anon):22340 kB Active(file): 361376 kB Inactive(file): 433088 kB Unevictable: 16 kB Mlocked: 16 kB SwapTotal: 1048572 kB SwapFree:1048572 kB Dirty:16 kB Writeback: 0 kB AnonPages:970412 kB Mapped: 323384 kB Shmem: 23008 kB Slab: 71760 kB SReclaimable: 44860 kB SUnreclaim:26900 kB KernelStack:6544 kB PageTables:22924 kB NFS_Unstable: 0 kB Bounce:0 kB WritebackTmp: 0 kB CommitLimit: 5074400 kB Committed_AS:3487604 kB VmallocTotal: 34359738367 kB VmallocUsed: 0 kB VmallocChunk: 0 kB HardwareCorrupted: 0 kB AnonHugePages:413696 kB HugePages_Total: 0 HugePages_Free:0 HugePages_Rsvd:0 HugePages_Surp:0 Hugepagesize: 2048 kB DirectMap4k: 168600 kB DirectMap2M: 8091648 kB but i only need: MemTotal:8051660 kB MemAvailable:6843080 kB Cached: 708336 kB event better would be if kernel would only tell me: 8051660 6843080 708336 if /proc is the only way to get this info, i wonder if creating a kernel module for this would be more efficient, or even possible?
