[gentoo-user] Automounting USB drives
Hello, Which package(s) do I need that allow: 1. A USB drive is inserted 2. The drive is mounted in some location automatically (e.g. /media/usbstick) 3. (2) happens even when the drive is an NTFS or FAT32 drive. 4. (1)-(3) happens even if I am not running a GUI 5. (1)-(3) happens even if I am running the GUI called TWM 6. (1)-(3) happens even if I am running the GUI called xfce4 7. (1)-(3) happens even if I am running the GUI called gnome 8. (1)-(3) happens even if I am running the GUI called kde 9. Bonus: if a GUI is runing, an icon appears on the desktop. This icon can be used to umount or to quickly navigate to the mounted directory. 10. Bonus: if you use words like dbus/policykit/consolekit/COM/DDE/OLE that allow me to get a technical understanding of the mechanisms in play. Thank you, Chris

Rich, Thank you again. My bash history shows ssh-agent being executed in the past, but I'm still not sure where gpg-agent came from. Using gpg-agent is considered a best practice in general, so I wouldn't go getting rid of it unless it is really causing you problems. You haven't mentioned what issue you're actually having with it/pinentry/etc. FYI pinentry frustrates me because: 1. pinentry-gtk and pinentry-qt do not allow me to paste my passphrase. My passphrase is difficult to type. I keep my passphrase in keepass. 2. Supposedly pinentry-curses will let me paste; however, pinentry-curses doesn't work. https://www.gnupg.org/documentation/manuals/gnupg/Common-Problems.html suggests that my problem is a misconfigured GPG_TTY environment variable. At this point though I'm not even interested in using it anymore. At the moment pinentry is no longer installed on my system so these problems should be gone. If/when I understand what is going on, I'll reinstall them. FYI I removed pinentry with: tail /etc/portage/package.use # 2014-07-05 Avoid pinentry dev-vcs/git -gpg mail-client/thunderbird -crypt tail /etc/portage/package.mask # 2014-07-05 Avoid password entry program that disallows paste app-crypt/pinentry Chris

[gentoo-user] How does ssh know to use pinentry?
I am trying to ssh into a site using PKI. I have a private key in my .ssh directory that requires a passphrase. ssh is asking me for my passphrase using a terrible program called pinentry. It's terrible for a bunch of reasons, and if you are interested you can just google pinentry sucks. pinentry is on my system because it is a dependency of gpg. gpg is on my system because I use thunderbird with +crypt (which is the default).

I was trying to use NFS because I always thought it odd that I have to jump through a bunch of samba hoops to share data among gentoo boxes. Is this a fair understanding: When setting up an NFS server to share data with people, first collect a list of UIDs from people around the world who will ever want to connect to this server. Modify the NFS server settings to incorporate these UIDs. If you cannot generate such a list, then an NFS server might not be right for you. You probably want to tweak your squash settings. I never have heard that term before, but I'm hoping to find something like this: Normally NFS requires you go compile a list of UIDs of people around the world who will ever connect to your server.

Alan, Thank you for explaining this in english for me. I am a bit blown away that it is taking me so long to figure out that NFS might not be for me. However, it is now making sense why everybody, even linux people, seem to use SMB. My problem: I have a handful of users on Mac and Linux who want to share some files whose content is not secret, but to avoid accidents I would like to restrict write access to those with a password. Most users are probably UID 1000 on their respective machines. Normally we use git for this, but we have 1TB of large binary files and do not need versioning. So I thought problem solved... I'll just make an NFS share. From your machines, just open nfs://share/ and when prompted for a username/password, just use one I'll supply. So this little plan of mine has hit several problems: 1. Accessing an NFS share from linux is not as simple as Please open nfs://foo/bar. At least not on XFCE4 (see my post http://mail.xfce.org/pipermail/xfce/2014-January/033023.html). It seems I have to get fstab involved. Not sure about from the mac. 2. Opening SMB is as simple as Please open smb://foo/bar. Perhaps this simplicity is due to the efforts of metacity/gvfs/fuse/samba/udev/polkit/consolekit. 3. NFS is UID based and I have no idea what the UIDs are, and worse, most of my users probably have the same UIDs on their system. This sounds like a show stopper to me. === Most NFS servers in the real world are thus file shares and permit read-only access to all users. Are you saying that NFS can be configured to allow ro access to everyone, even those people whose UID was not known when the NFS was setup? If so, can the same be done for rw access? squash was invented - when root access comes over the wire, the server changes it from UID=0 to something else (usually nobody) and then applies Unix permissions to that account. Got'cha. If I go with NFS, I think I would be interested in is more of a global squash. No matter which UID is making the connection, squash it over to the generic local UID which was granted rw access to the share. Thanks again, Chris

[gentoo-user] Mounts NFS in XFCE4
Hi, Is it possible to mount an NFS share from XFCE4? I suspect the answer might have something to do with gvfs or fuse, neither of which I know anything about. Ideally after emerging or USEing I will have a Connect to server entry in my XFCE4 menu. If this is impossible, then I'd be ok with an approach that will allow a regular user to mount any network share with the mount command. Thank you, Chris

[gentoo-user] Preparing a shared USB stick
Hello, Please consider a USB stick that is unformatted but is to be used by multiple people/machines. Ideally your instructions will work for all people/os/WM, but if necessary please assume that everyone is running gnome under linux 1. How should I prepare this device so that it can be plugged into any machine and will be writable by anyone? I suspect the answer will involve words like fdisk, mkfs.xxx, mkdir/mount, chmod/chown. I'm most interested in the chmod/chown part. 2. How can I prepare the device so that files/directories added by people in the future will continue to be writable by anyone? 3. How can I ensure that all files will appear to have the same owner; or, if this is not important, can you explain why it should not be a problem. And of course if you can refer me to a document that explains this I'm happy to read it. Thank you, Chris

Mick, I've been running nvidia-drivers on my Gentoo laptop for three years and have two major problems: 1. Any particular nvidia driver version is only compatible with only certain kernel versions. This condition is due to the way the NVIDIA driver works. Gentoo portage was just not designed to handle such a rule package x requires kernel y so it is left to us users to deal with via masks. For some reason (?) I only had to deal with this rule during the period ~July 2013 - October 2013. 2. The latest stable version of the nvidia drivers do not allow gnome-terminal windows to close. This problem too just started happening after years of trouble-free gnome-terminal closing. It is frustrating... but I'm stuck with NVIDIA-drivers because I use CUDA. If 1) this sort of thing bothers you and 2) radeon doesn't have similar problems, then by all means please switch to radeon and let us know how it goes!

[gentoo-user] USB disk automatically mounting: how does it work
Hello, Would you please explain (or refer me to a place that explains) the mechanism by which an USB drive appears on my desktop? I'm looking for a level of detail like this: When you insert a USB device, the kernel sends out a notification A. Userland daemons such as B can catch this signal. A file B.conf describes what to do in response to a certain class of USB devices and in there you will see a section for disk drives that says mount them at location C. Then B sends out a notification D which window managers can catch if they want. GNOME and others catch D and in response put an icon on the desktop. The reason lowly users can mount and write to these devices is E. PS: These topics are a blur in my mind: udev hotplug coldplug session pam. I suspect these words are used to fill in some of the variables in my pseudo-description above. Thank you, Chris

Presumably these names are made available through system calls. What is the name of the system call that provides these monikers? I'm curious by what moniker systemcalls refer to these devices. For example, is the systemcall that retrieves these monikers called GetEthernetNames? What you CANNOT do with udev is eg switch the names eth0 and eth1 around after the kernel has named them. That was tried for years, it doesn't work. So now udev never interferes with kernel namespace, it create it's own namespace Okay. From your description I conclude that there are two classes of names for ethernet devices. Kernel ethernet names and udev ethernet names. When a userland utility (wuch as ifconfig) takes an ethernet device name as input are they expecting a kernel ethernet name or the udev ethernet name? That question can be answered with a simple kernel or udev but I'm interested in a little more detail. What do these userland utilities do with the name? Are these utilities calling systemcalls such as GivePropertiesOnEthernetNameInKernelNamespace(eth0)? Are they establishing a connection to a udev server and querying based on udev namespace names? The goal of these questions is not for me to determine if udev is good or bad, debate global warming, etc. I just want to technically understand these names, what their differences are, where they come from, how they are referred in various function calls, etc. Chris

Can you temporarily disable it and see how the sound comes out? Walter, Thank you for your tip. This is the sort of thinking that will ultimately lead to a solution. I installed audio a couple years ago when setting up Gentoo on this machine for the first. time. I followed the handbook. Since that day I never again looked at my sound card setup. I do not know what is a sound server and I certainly never installed one (unless part of the install handbook has me install one). Assuming for a moment that I did install a sound server and that I want to disable it in order to perform your test, 1) How do I determine which sound servers, if any, are installed? 2) How do I disable them?

[gentoo-user] Poor sound quality
Hello, My sound started sounding like crap ~6 months ago. Imagine someone has control of my volume knob and is quickly (~5Hz) turning the volume knob up and down. That is a rough idea of what it sounds like. This happens whether I am listening a beautiful song or whether I'm listening to 'white noise'. Happens with my laptop speakers or with headphones. Can anyone hazard a guess as to what is wrong? FYI I'm using a Dell M6600 with the same amd64 gentoo install for ~2 years. Thank you, Chris
[gentoo-user] Lilo EBDA is big yet computer boots (multiple choice)
Hello, 1. When my machine boots, just after I tell lilo which kernel to load, lilo reports EBDA is big; kernel setup stack overlaps LILO second stage 2. I chose lilo over grub because of some gentoo handbook comment about multilib that frightened me. 3. My machine boots fine. I have to be paying close attention to even see that message since the screen quickly clears during the kernel boot sequence. 4. I do not know how long this has been happening, but I just noticed it today. Possible coincidence: just upgraded gcc and recompiled world and the kernel today. 5. I ran /sbin/lilo after compiling and installing the kernel. I even ran it a few more times just to be on the safe side. === Question: Why am I getting the error EBDA is big? a) You did not run /sbin/lilo after installing the kernel [FALSE see (5)] b) There is something very wrong and your machine is unable to boot [FALSE see (3)] c) Just be thankful your machine boots. Don't you have anything better to worry about? d) Use grub and hope that this problem goes away without really understanding it. e) People get this message yet are able to boot when their kernels are too big.

[gentoo-user] Which tool to diagnose wireless connection problem?
Hello, I never really understood wireless in linux, it has always just worked. I use wicd although I don't really even know what that means. I have no clue what is a wpa supplicant, ndis, etc. I now have a problem. Please point me toward the tools I should use to diagnose and fix the problem. I tried to fix this problem by running wicd-client from the command line hoping to see some stderr messages to help diagnose, but no luck. Also dmesg is not helpful. Problem: I used a linksys router for years. It appeared as a single SSID that I connected to. Configured with wicd-client. Everything worked great under gentoo. I throw away the linksys and purchase a new apple airport express. This router works fine with my apple machines. On gentoo, wicd-client shows two SSIDs with identical names for this one router! One is on channel 11 and one is on channel 157. Not sure this matters. I specify my password for both of them and specify one of them to connect automatically. The connection with one (or both?) of the SSIDs stays live for 5-10 minutes, then disconnects. I can get it to reconnect by simply opening wicd-client, highlighting one of the two SSIDs, and clicking connect. Repeat every 5-10 minutes. Question: What tools or logs can I use to understand why my wireless connection disconnects every 5-10 minutes? FYI this is what dmesg says during one of these disconnect/reconnect cycles: [55519.603007] cfg80211: Calling CRDA to update world regulatory domain [55520.041137] iwlwifi :03:00.0: L1 Enabled; Disabling L0S [55520.041381] iwlwifi :03:00.0: Radio type=0x0-0x3-0x1 [55520.195568] ADDRCONF(NETDEV_UP): wlan0: link is not ready [55520.494633] e1000e :00:19.0: irq 44 for MSI/MSI-X [55520.595455] e1000e :00:19.0: irq 44 for MSI/MSI-X [55520.598916] ADDRCONF(NETDEV_UP): eth0: link is not ready [0.414298] iwlwifi :03:00.0: L1 Enabled; Disabling L0S [0.414523] iwlwifi :03:00.0: Radio type=0x0-0x3-0x1 [0.551957] ADDRCONF(NETDEV_UP): wlan0: link is not ready [55966.719991] iwlwifi :03:00.0: L1 Enabled; Disabling L0S [55966.720250] iwlwifi :03:00.0: Radio type=0x0-0x3-0x1 [55966.863374] ADDRCONF(NETDEV_UP): wlan0: link is not ready [55967.147380] e1000e :00:19.0: irq 44 for MSI/MSI-X [55967.248317] e1000e :00:19.0: irq 44 for MSI/MSI-X [55967.251736] ADDRCONF(NETDEV_UP): eth0: link is not ready [55967.301004] iwlwifi :03:00.0: L1 Enabled; Disabling L0S [55967.301252] iwlwifi :03:00.0: Radio type=0x0-0x3-0x1 [55967.452333] ADDRCONF(NETDEV_UP): wlan0: link is not ready [55969.637135] wlan0: authenticate with 7c:d1:c3:cd:b9:be [55969.641690] wlan0: send auth to 7c:d1:c3:cd:b9:be (try 1/3) [55969.643564] wlan0: authenticated [55969.643873] wlan0: associate with 7c:d1:c3:cd:b9:be (try 1/3) [55969.647304] wlan0: RX AssocResp from 7c:d1:c3:cd:b9:be (capab=0x431 status=0 aid=1) [55969.654396] wlan0: associated [55969.657270] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready Thank you, Chris

[gentoo-user] WM that does not require policykit, consolekit, and gudev
Hello, I installed twm to test my xorg as per the gentoo install docs. Works great! Then I decided to install what I thought would be a lightweight WM: xfce4 with emerge -vat xfce4-meta. Unfortunately emerge didn't want to continue without some changes from me involving USE flags gudev, policykit, and consolekit. At this point I see three options: 1. Understand gudev, policykit, and consolekit and not be frightened of them (a tall order given the google results I am getting). Then enable the USE flags and install xfce4-meta 2. Do not attempt to understand the USE flags and enable them anyway (frightening given all the polictykit and consolekit chatter I see on google) 3. Select another WM that is more lightweight and doesn't require these USE flags. I'm leaning towards (3). Can you recommend a WM that will not require me to enable gudev, policykit, and consolekit? Thank you, Chris
[gentoo-user] Gentoo is the best linux distro
Gentoo is the best distribution I have used (I haven't used too many: ubuntu, fedora, gentoo). I love the USE flags. I love watching (and questioning) what is going to be installed. I love emerge.

With ubuntu, for example, I had trouble with sound and ethernet cards that I could never figure out... and the kind of answers I get on their forums drive me insane (my uncle once said that his cousin typed this magical command and it worked fine for a little while so maybe try that).

I installed xfce4-meta and was a little surprised to see it did not come with thunar. When I tried to install it, portage became upset. Question: is it normal that I would have to ~amd64 a bunch of packages and deal with slot conflicts and static-libs to install a file manager? FYI I am running a stable (non-~AMD64) system. Thank you, Chris === # emerge -pv xfce-base/thunar These are the packages that would be merged, in order: Calculating dependencies... done! !!! Multiple package instances within a single package slot have been pulled !!! into the dependency graph, resulting in a slot conflict: dev-libs/libgcrypt:0 (dev-libs/libgcrypt-1.5.0-r2::gentoo, ebuild scheduled for merge) pulled in by dev-libs/libgcrypt[static-libs] required by (sys-fs/cryptsetup-1.4.1::gentoo, ebuild scheduled for merge) (dev-libs/libgcrypt-1.5.0-r2::gentoo, installed) pulled in by (no parents that aren't satisfied by other packages in this slot) sys-libs/zlib:0 (sys-libs/zlib-1.2.5.1-r2::gentoo, installed) pulled in by (no parents that aren't satisfied by other packages in this slot) (sys-libs/zlib-1.2.7::gentoo, ebuild scheduled for merge) pulled in by =sys-libs/zlib-1.2.6 required by (sys-apps/kmod-10::gentoo, ebuild scheduled for merge) dev-libs/popt:0 (dev-libs/popt-1.16-r1::gentoo, ebuild scheduled for merge) pulled in by =dev-libs/popt-1.16-r1[static-libs] required by (sys-fs/cryptsetup-1.4.1::gentoo, ebuild scheduled for merge) (dev-libs/popt-1.16-r1::gentoo, installed) pulled in by (no parents that aren't satisfied by other packages in this slot) dev-libs/glib:2 (dev-libs/glib-2.32.4::gentoo, ebuild scheduled for merge) pulled in by =dev-libs/glib-2.32.4:2 required by (dev-util/gdbus-codegen-2.32.4::gentoo, ebuild scheduled for merge) (and 3 more with the same problem) (dev-libs/glib-2.30.3::gentoo, installed) pulled in by (no parents that aren't satisfied by other packages in this slot) It may be possible to solve this problem by using package.mask to prevent one of those packages from being selected. However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically.

[gentoo-user] Adding a use flag: hwdb
Hello, Background: I enable USE flags by adding them to /etc/portage/package.use. This file is filled with all sorts of personal preference customizations of my system. This file does not contain required system USE flags. A month ago emerge insisted that I enable a USE flag ruby_targets_ruby19 to a bunch of packages on my system. Feeling uncomfortable adding a system required USE flag to package.use (vs personal preference customization), I posted to this list and indeed learned that I was going about it all wrong! In that particular case, I should have added 'RUBY_TARGETS=ruby18 ruby19' to /etc/make.conf. Actually, the Gentoo team should add this to the profile... presumably they will eventually do this or have done so already. Question: Today emerge is asking me to add =sys-fs/udev-171-r6 hwdb to package.use to appease udisk. Just as before, this looks fishy to me and I would like to get your opinion about how to properly satisfy this seemingly system-required-use-flag. My gut instinct is that this USE flag requirement should be handled by the Gentoo team in the profile or in some other place that I never look at. What do you guys think? Should I append udev hwdb to package.use right after my long list of personal preference customizations? Thank you, Chris PS: A snippet from my /etc/portage/package.use: # Give a GUI to cmake dev-util/cmake qt4 # Enable nice mounts in gnome gnome-base/gvfs fuse # Enable plotting in octave sci-mathematics/octave gnuplot # Enable GNOME right-click to create targz app-arch/file-roller nautilus # Satisfy a dependency I do not understand needed by a package I never heard of =sys-fs/udev-171-r6 hwdb

Thank you for all your patient help. I've been using Gentoo for years
and for some reason this RUBY thing has me flustered.
1. What on my system is insisting on make.conf RUBY 1.9 USE_EXPAND
changes? An emerge --tree is not giving me a clear answer (as it
usually does). The original post in this thread provides a pastebin
link to back up this claim.
2. If the answer to (1) is the gentoo system itself, then why
doesn't the gentoo system itself update the USE_EXPAND by adding a
reference to ruby19? It appears the gentoo system itself presently
only enables the ruby18 USE_EXPAND.
base $ find /usr/portage/profiles/ | xargs grep RUBY_TARGETS=
/usr/portage/profiles/base/make.defaults:RUBY_TARGETS=ruby18
3. If the answer to (1) is package foo, I'm tempted to remove
package foo or USE it with -ruby or eat my words and admit that I am
a RUBY user and need to understand the nuances.
4. I run a stable system that is somehow insisting on ruby19. This
webpage http://www.gentoo.org/proj/en/prog_lang/ruby/index.xml says
ruby19 is not for use on production systems. Why the disconnect?
Perhaps the ruby page is just out of date.
5. I have no idea what RUBY is and have never installed it directly.
Yet I have to understand RUBY USE_EXPANDs which seem to be described
only in the RUBY installation guide, gentoo dev manual, or in ebuild
scripting guides. I am a gentoo layperson in general and am
completely clueless about RUBY in particular. I believe talk about
this required and automatically installed package should appear not
in obscure dev documentation, but in the handbook. Perhaps with more
time/volunteers this would have happened.
6. Why does emerge insist on me adding USE=ruby_targets_ruby19 to a
bunch of projects, yet the users of this group recommend a change in
make.conf? I suspect the disconnect that the two approaches are
equivalent, just emerge does not have the street smarts to recommend
the proper change.
Thank you for listening to me list the issues I am ignorant on. Now
I'm going to add RUBY_TARGETS=ruby19 to my make.conf and hope things
just work.
Thank you again,
Chris
