[SOLVED] How to choose a fast mirror for net-install?

Coming back to Arch after some time away. Sitting here looking at the AIF screen asking me to select a mirror from a huge list. So, how to determine, without another machine running Arch (or, for that matter, any other Linux distro), which mirror to choose? Shouldn't rankmirrors be behind the scene to build a very short list for this? Welp, wish me luck, literally.
Solved: Since rankmirrors is on the net-install disk along with the mirrorlist...duh. Just didn't occur to me until after I posted.

If you right click on an empty container or a container with an object in it, it has the same available choices to select. However, if you create a blank property node on the block diagram, and wire up the .net object to it, you will see a much different list of properties.
So, the property node created from right clicking a .NET container will be for that container, even if there is an object inside. To create a property node for the object, you must wire the .NET object to an empty property node on the block diagram.

So how to specify different answer file for different install images in WDS snap-in?

hello
in WDS snap-in, in properties on server name, on client tab, we can define an answer file for unattended windows installation on WDS clients.
my question is, maybe we have added multiple images in WDS snap-in (win xp image, win 7 , win 2008,...)
now this one answer file applies to all of them ?
so how to specify different answer file for different install images in WDS snap-in?
thanks in advanced

Under the "Client" tab of WDS, you should only use an answer-file with settings relevant for the installation. This would be credentials for the WDS deployment share, international settings used during the setup and possibly also destination drive
details (if you want the installation to take care of partitioning the disk etc). The settings relevant for unattend-files used under "Client" would only be of those in phase 1 (WinPE).
However, if you would like to have specific unattend file for every installation, e.g. Win7, Server 2008, Win 8 etc, you can browse to the image under "Install Images" under the image Groups. There you can select properties for every image and
have a personal unattend-file.
hi Joel
very cool. thanks a lot, that really helped me.

[SOLVED] How to set the packager name for an AUR package?

Hi,
I'm maintaining an AUR package (fspcc), but I don't know how to set the name of the "packager" for that package.
E.g. when you request info about some package
$ pacman -Qi somepkg
there is a line
Packager: Unknown Packager
that specifies the packager.
How do I set this "Packager" info so that any user installing my package will see what I want?
Last edited by lisztinf (2014-04-13 13:39:43)

Thanks for the answer.
I guess that when I run
$ makepkg
in my local build directory, then "mkpkg" will build a package with the "Packager" info set accordingly to my local makepkg.conf.
However, I would like another user - with his own makepkg.conf - to see what I want when installing the package. How can I achieve this?
If I install an official package - say pacman itself - through ABS, I see the "Packager" field properly set for that official package. But certainly this info doesn't come from my local makepkg.conf. I would like the same behaviour for my package. Is it possible?

Any ideas on how to do a local mirror for this situation?

I'm starting a project to allow ArchLinux to be used on a Cluster environment (autoinstallation of nodes and such). I'm going to implement this where I'm working right now (~25 node cluster). Currently they're using RocksClusters.
The problem is that the connection to internet from work is generally really bad during the day. There's a HTTP proxy in the middle. The other day I tried installing archlinux using the FTP image and I took more than 5 hours just to do an upgrade + installing subversion and other packages, right after an FTP installation (which wasn't fast either).
The idea is that the frontend (the main node of the cluster) would hold a local mirror of packages so that when nodes install use that mirror (the frontend would use this also, because of the bad speed).
As I think it should be better to only update the mirror and perform an upgrade not very often (if something breaks I would leave users stranded until I fix it), I thought I should download a snapshot of extra/ and current/ only once. But the best speed I get from rsync (even at night, where an HTTP transfer from kernel.org goes at 200KB/s) is ~13KB/s this would take days (and when it's done I would have to resync because of any newer package that could have been released in the meantime).
I could download extra/ and current/ at home (I have 250KB/s downstream but I get like ~100KB/s from rsync), record several CDs (6!... ~(3GB + 700MB)/700MB) but that's not very nice. I think that maybe this would be just for the first time. Afterwards an rsync would take a lot less, but I don't know how much less.
Obiously I could speed things a little If I download the full ISO and rsync current using that as a base. But for extra/ I don't have a ISOs.
I think this is a little impractical (to download everything) as I wouldn't need whole extra/ anyways. But it's hard to know all packages needed and their dependencies to download only those.
So... I would like to know if anyone has any ideas on how to make this practical. I wouldn't wan't my whole project to crumble because of this detail.
It's annoying because using pacman at home, always works at max speed.
BTW, I've read that HOWTO that explains how to mount pacman's cache on the nodes to have a shared cache. But I'm not very sure if that's a good option. Anyway, that would imply to download everything at work, which would take years.

V01D wrote:After installation the packages that are in cache are the ones from current. All the stuff from extra/ won't be there until I install something from there.
Anyway, if I installl from a full CD I get old packages which I have to pacman -Syu after installation (that takes long time).
Oh, so that's how is it.
V01D wrote:
I think I'm going to try out this:
* rsync at home (already got current last night)
* burn a DVD
* go to work and then update the packages on DVD using rsync again (this should be fast, if I don't wait long time after recording it)
And to optimize further rsync's:
* Do a first install on all nodes an try it out for a few days (so I install all packages needed)
* Construct a list of packages used by all nodes and frontend
* Remove them from my mirror
* Do further rsync updates only updating the files I already have
This would be the manual approach of the shared cache idea I think.
Hmm... but why do you want to use rsync? You'll need to download the whole repo, which is quite large (current + extra + testing + community > 5.1GB, extra is the largest). I suggest you to download only those packages and their dependencies that you use.
I have similar situation. At work I have unlimited traffic (48kbps at day and 128kbps at night), at home - fast connection (up to 256kbps) but I pay for every megabyte (a little, but after 100-500 megabytes it becomes very noticeable). So I do
yes | pacman -Syuw
or
yes | pacman -Syw pkg1 pkg2 ... pkgN
at work (especially when packages are big), then put new downloaded files on my flash drive, then put them into /var/cache/pacman/pkg/ at home, and then I only need to do pacman -Sy before installing which takes less than a minute.
I have 1GB flashdrive so I can always keep the whole cache on it. Synchronizing work cache <-> flash drive <-> home cache is very easy.
P.S.: Recently I decided to make complete mirror of all i686 packages from archlinux.org with rsync. Not for myself but for my friends that wanted to install Linux. Anyway I don't pay for every megabyte at my work. However it took almost a week to download 5.1 GB of packages.
IMHO for most local mirror solutions using rsync is overkill. How many users are there that use more than 30% of packages from repos? So why to make full mirror with rsync when you can cache only installed packages?

[SOLVED] how to use diffrent iptables rules for different ppp account?

(You establish PPPoE sessions over the local network to the Arch machine? Which then routes the traffic?)
first question ,yes that is exactly what i am done. second question i also have a small scripts on windows pc to solve routes traffic problem
route -p delete 0.0.0.0
route -p add 192.168.9.0 mask 255.255.255.0 192.168.9.1
route -p add 0.0.0.0 mask 0.0.0.0 192.168.22.0
but after a while i found scripts is not necessary because windows always attempt to use PPPoE sessions as default internet connection local connection is also ok
and use -i pppX in my iptables rules dose not solve my problem , because same account start PPPoE session could be marked as ppp0 or ppp1. it is hard to identified which account start session.

How to choose an external harddrive for booting an iMac G5 (Intel Core 2 Duo, late 2006 model MA589xx/A)

The internal harddrive of my 20" iMac G5 has failed and I would like to run the computer from an external drive until I can purchase a new one. I don't currently have an external drive available to do this so I would like some recommendations regarding which type would be preferable for this use. My neighbor suggested buying an external firewire enclosure and a 500 GB drive to go inside it. Is that adequate? If so, which brand is good to buy. In the future I will be using this new drive to backup files from whatever computer I end up purchasing. I am also considering replacing the internal drive of the iMac since the rest of the computer works well and, if possible, would like to use this new drive for that purpose.

I agree with your neighbor. A good source is OWC. You want a 3.5" SATA I or SATA II (1.5 or 3.0 Gb/s) hard drive. The enclosure should have a power supply and support at least Firewire 400/800 and USB 2.0. OWC even has tools. Good drives to choose from include Seagate, HGST, and Western Digital (stay away from their Blue drives.) Avoid so-called Green drives.

[Solved] How to use Oracle Java 6 for specific applications

I use an IDE called PyCharm. On its download page, it recommends using Java 6 instead of OpenJDK. I currently have jdk7-openjdk installed, and from what I had read in the Arch Wiki on Java, it should be possible to install Oracle Java 6 along side OpenJDK 7.
However, after installing jdk6-compat and jre6-compat, I still see that I am running OpenJDK 7 when I run the following:
% java -version
java version "1.7.0_09"
OpenJDK Runtime Environment (IcedTea7 2.3.3) (ArchLinux build 7.u9_2.3.3-1-x86_64)
OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)
...even after I have set JAVA_HOME and added /opt/java6/bin to my path.
How can I get PyCharm (or other applications) to use Oracle Java 6 instead of OpenJDK?
Thanks, and apologies if I've posted in the wrong place.
Other information that might be helpful:
Running zsh as default shell
Using Gnome 3 as DE
Last edited by Nikorasu (2012-11-17 20:54:33)

I found the solution.
For Pycharm, I just needed to add an environment variable PYCHARM_JDK. For running specific applications, I asked this question on the Unix / Linux StackExchange and got an answer there.
Also, after running PyCharm in Java 6... I would not recommend it. OpenJDK works fine

[SOLVED] How to set DEVPATH and DEVNAME for Fancontrol?

Hello
Ok, no one answered, my question was a bit unclear - so I rewrote it
I am setting up fancontrol according to https://wiki.archlinux.org/index.php/fan_speed_control, but I do not understand the last part about setting the DEVPATH and DEVNAME:
"There are also two settings fancontrol needs to verify the configuration file is still up to date. The lines start with the setting name and a equality sign, followed by groups of hwmon-class-device=setting, seperated by spaces. You need to specify each setting for each hwmon class device you use anywhere in the config, or fancontrol will not work. "
As suggested - when I run:
readlink -f /sys/class/hwmon/hwmon-device/device | sed -e 's/^\/sys\///'
I get no output
As suggested - When I run
sed -e 's/[[:space:]=]/_/g' /sys/class/hwmon/hwmon-device/device/name
I get
sed: can't read /sys/class/hwmon/hwmon-device/device/name: No such file or directory
I do not undestand what the two commands from the wiki do - what do they do and how can I set it right?
Any questions or info you need, just ask pls.
Regards
Martin

Hello,
First command
So what does the wiki meen by: "DEVPATH sets the physical device. You can determine this by executing the command
readlink -f /sys/class/hwmon/hwmon-device/device | sed -e 's/^\/sys\///'"
Physical device of what, and what output am I suppose to get: Nothing, a list with output on where the symlinks lead, something else... In my case I got no output, if that is right, I do not know - since I do not understand what the command do.
Seccond comand
DEVNAME: Sets the name of the device. Try:
sed -e 's/[[:space:]=]/_/g' /sys/class/hwmon/hwmon-device/device/name
Does it meen like this - If I during my pwmconfig used hwmon1 wich was coretemp, and hwmon2 wich was nct6775, I should do:
sed -e 's/[[:space:]=]/_/g' /sys/class/hwmon/hwmon1-device/device/name coretemp
sed -e 's/[[:space:]=]/_/g' /sys/class/hwmon/hwmon2-device/device/name nct6775
And that will direct every occurrence of hwmon1 and hwmon2 to the correct sensor chip?

How to choose a right server for Oracle Database!

Hi all,
Is there any formular that allows me to find the appropriate server configuration for Oracle database 11g?
Please help!
Thank you all.
Dan.
Edited by: Dan on 01:45 06-01-2013

Simply put ... no.
Determining the correct server is a dance between hardware vendors (one point of input to be treated with general distrust), internal expertise and experience working with similar systems, and most importantly understanding the behaviour of what you are building.
Here are some sample questions to start the ball rolling.
1. What operating system expertise does your organization have?
2. What operating system expertise is readily available in the community from which you hire applicants?
3. What type of application?
4. What are up-time expectations?
5. Requirements for high availability?
6. Requirements for time to perform a full recovery?
7. Requirements for security?
8. Storage footprint (dictates internal storage versus SAN, NAS, or ZFS)
9. Anticipated growth (3-7 years)
Everyone wants to sell you CPU clock-ticks, more RAM, more IOPS, etc. But the first thing you need to understand is the capabilities you require that are generic: Required of any solution. Only when you have a clear understanding of these factors are you ready to discuss whether the solution is a pizza box or an ODA ... an Exadata or an IBM System Z.
Far too often I find people purchasing RAM they don't need with CPU speeds that exceed the ability of their network infrastructure to move the data so pay special attention when you are ready to make your purchase to engineered systems like the ODA.

How to choose an air printer for OS Mountain Lion 10.8.3

I am needing a printer for my macbook pro. Would like a multi-function laser printer that will print wirelessly. In reading the reviews on the Apple site, most of them are bad and talk about not working with the operating system. I will be using it for printing shipping and mailing labels, and general use printing. Does anyone have a printer that they would recommend? Your help is appreciated.

My old Brother printer has churned out 60,000 pages and is still going strong. And it has worked without problems on every OS version since 10.4. That model is no longer being sold, but i would recommend the Brother brand without reservation.

Hello!
You just need to install "libgnomeui". This package (or some of it dependencies... I never "investigated" what exactly happens) provides what is necessary to make Qt applications use the GTK theme. Probably it is going to work right after the installation. If not, try to logoff/login or restart the computer. And, as a "last resort" (it should not be necessary), change the Qt settings, on "qtconfig", to make it use the GTK+ Gui Style.
I hope this have worked. Anything else, just ask!

[SOLVED] How do I find out what packages are installed in a distro?

Okay. I was running Arch before, but GNOME had a bunch of problems that I couldn't fix myself, so I reformatted and went to Peppermint OS (it's a cloud-based system), and I absolutely love it. Now, the thing is, it's even slower than my Arch system was running GNOME, and it's supposed to be super-lightweight and speedy; but aside from that, I found it's a great distro (I think most of the slowdown is because it's based on Ubuntu and Mint). So, my question: how do I find out which packages are in Peppermint OS so I can emulate the basic environment, except with Arch underneath? Thanks, guys!

How do i delete an App for re-installing

Hi all, i have a few App's that are for editing images, i wanted to use one of them yesterday, the first two i tried to open both came up with the same message, the message was telling me i had purchased it on another computer and i should sign in using the ID i used to purchase it etc.
I know for a fact that i only have one Apple computer and i only have one Apple ID , i truly dont understand it at all.
And then after not being able to type in the correct password, it comes up with another message telling me the App is damaged, i should delete it and download it again etc. etc. what a mess.
happily i did find one of my other Image Apps did the job , but i would love to know WHAT IS GOING ON ?
therfore the least i can do is to delete it and download it again, so please how am i supposed to DELETE it ?
tim

Hey Jag!
If you are certain that you no longer want an app, not even in your history, you can delete it using iTunes on your computer. This will mean that things will become as if you never purchased this app and you would have to purchase it AGAIN if you want it back. Do that ONLY if you are absolutely certain you have no need for it, unless you like spending money.
Go to iTunes Store Home.
On left side of screen, click on Purchased
Select Apps from the options at the top of the screen
Select either iPhone or iPad from the middle top of the screen
Run your mouse (or trackpad) pointer over the icon of the app you want to remove.
Click on the circled (x) at the top left corner of the icon.
Follow instructions.
If all you want is an app deleted from your iOS device, get the app icons to wiggle (press and hold any icon for a few seconds) then tap on the circled (x) at the top left of the icon. That will delete the app from your device, but you can still put it back on for free by going to the App Store, Updates-> Purchases.
Good luck

[SOLVED] How to get Broadcom wireless to work (Arch install)?

I'm very newbie in network managment (and in Linux in general), and it's my first time installing Arch.
I came from Debian/Ubuntu. In Ubuntu 14.04 it was working already, and in Debian 7.8 I only had to install the package "brcmsmac" to get my wi-fi card to work.
But now I have no idea what I'm doing in Arch. I've already downloaded and installed the system using the auto DHCP connection, but after the chroot I got confused, now I'm stuck in configuring the network and wireless. I didn't even install a bootloader yet. (I'm using another computer to post this)
I followed https://wiki.archlinux.org/index.php/Beginners%27_guide and https://wiki.archlinux.org/index.php/broadcom_wireless, and Google'd about it but everything seems confusing.
I won't need anything special like a server, so I imagine the solution is very basic and newbie.
It's probably a very simple thing to do, like installing a package or loading something, and I don't want to mess up my system.
I heard about AUR but I don't know how to use it.

We need *a lot* more info than that. Could be something very simple, like the interface being up before starting wifi-menu (netctl doesn't like the interface being up, it'll only start correctly if the interface is down).
Or it could be something more. In which case, you'll need to start wpa_supplicant manually with debugging enabled:
wpa_supplicant -i wlp18s0b1 -c <(wpa_passphrase MYSSID passphrase) -d
Once this says you're connected, open another terminal and start dhcpcd. Or, if wpa_supplicant doesn't manage to connect, post the *entire* output.
Edit: Ok, you posted more info as I was writing my post. Will look through that, maybe it contains something useful. If not, follow the instructions above.
Edit2: Nope, nothing about wireless in there, except that the driver loaded.
It worked!!
I was looking into the logs and found an authentication failure...my password is very long so I made some mistakes while typing it.
So this is the solution all the way:
SOLUTION:
- No need to install or load any external drivers (all I used was already in the base installation)
- DISABLE THE HIDDEN NETWORK OPTION IN THE ROUTER (thanks for the heads-up @Gusar)
- run "# wifi-menu"
or
"# wpa_supplicant -i [interface] -c <(wpa_passphrase MYSSID passphrase) -d"
- run "# dhcpcd [interface]"
- Good to go!!
I'm sorry for the trouble guys, and like I imagined, it was really easy and now I see my newbiness hahaha ;D
Thanks.

How to automate "do not authorize" for scripted install?

I am a consultant for a library and they want to install Digital Editions on all patron and staff pc's. I've created a script (accor
ding to the documentation) which works well (silent install, no CRC check, etc). But the first time Digital Editions 1.72 is run, it
prompts for "authorization" or "do not authorize". Being a library, they don't want content stored locally, etc so they want the
"do not authorize" option. Is there a way this can be automated in the script? All computers are Windows XP with SP3 and the domain is Windows Server 2003.

ok, thanks, i was afraid that might be the case.
