Re: [gentoo-user] Kernel options and udisk
True... Had I only one computer, I would've gone the USB 3 route... 2 ext HD, I backup to one for one or two weeks, then deposit the drive to an off-site location, swapping it with the other HD, and use the second HD for the next period. Problem is, using a USB drive means I have to move it around, and I'm lazy, so it won't work for me... That's why I opt for a networked solution... Hmm, that begat an interesting thought, though... Anyone knows of a cheapo box (appliance) with USB 3.0 that can expose an external HD to the network?

[gentoo-user] Kernel options and udisk
Howdy, I was doing a update a while back and noticed a ewarn, enotice or something going by. I used the elogviewer to go back and dig it out. This is what it says: Found sources for kernel version: 3.5.0-gentoo Checking for suitable kernel configuration options... ERROR (setup) CONFIG_USB_SUSPEND: is not set when it should be. WARN (setup) Please check to make sure these options are set correctly. Failure to do so may cause unexpected problems. So, I go into the kernel's menuconfig and find this: │ CONFIG_USB_SUSPEND: │ │ │ │ If you say Y here, you can use driver calls or the sysfs │ │ "power/control" file to enable or disable autosuspend for │ │ individual USB peripherals (see │ │ Documentation/usb/power-management.txt for more details). │ │ │ │ Also, USB "remote wakeup" signaling is supported, whereby some │ │ USB devices (like keyboards and network adapters) can wake up │ │ their parent hub.

Well, I don't think I need USB remote wakeup or anything so I don't think I need this but at the same time, udisk is giving me notice that it should be there. This is a desktop system not a laptop. Do I need to listen to me not needing it or udisk that says I do? Opinions? Dale :-) :-) P. S. The only things I have USB right now is my printer and a camera. I may have a UPS added to that when I get around to rebooting again. I'm not sure on how I will end up connecting it yet. -- I am only responsible for what I said ...

David told me that he could only check the bug on monday, so I did a little research on the weekend. I installed Gentoo in a QEMU VM (using gnome-boxes), to see if I could reproduce the bug in a unmodified Gentoo installation (I use my systemd-only overlay). I could reproduce the bug, but I found a reasonable workaround: cat /etc/portage/package.use/no-systemd gnome-base/gdm -systemd gnome-base/gnome-session-systemd gnome-base/gnome-shell -systemd sys-auth/polkit -systemd If those four packages have systemd support disabled, then everything works as expected (the suspend/hibernate options returns, I can mount/umount USB sticks, etc.) If at least one of those packages have the systemd USE flag, then the bug appears. I updated the bug report (and I'm not really sure the bug is in polkit or gnome-shell): https://bugs.freedesktop.org/show_bug.cgi?id=53905 This workaround also works in my systemd-only overlay. So, if you have the systemd flag in any of those four packages, disable it and everything should work. Just to be explicit, the versions are: gnome-base/gdm-3.4.1-r1 gnome-base/gnome-session-3.4.2.1 gnome-base/gnome-shell-3.4.2 sys-auth/polkit-0.107:0 I was really looking forward to use the integration of systemd into GNOME, but I suppose it's still a little green. Hopefully we will find and fix the exact bug soon; meanwhile, this workaround is much more usable than using pmount, pm-suspend, etc. Regards. -- Canek Peláez Valdés Posgrado en Ciencia e Ingeniería de la Computación Universidad Nacional Autónoma de México

The one that died was an OCZ 1010 W supply, which is way too much for this machine. I used to have 12 hard drives in here (Thermaltake Full Armor), but a few years ago I built a server to do those tasks. I replaced it with a platinum 650 W rated supply. The new PSU looks like it's built a lot better. I already have three 12 cm fans that are controlled by the BIOS. I've had really poor luck with OCZ anything (to the point that I won't buy anything they make anymore.) Dan

Re: [gentoo-user] Offline Update
A few years ago, I used to run gentoo offline.

You can take this list to a connected place, download the files and put it into /usr/portage/distfiles/. If useful, I can give it to you (but I don't know if it still works). 2012/9/16 Dale > Alan McKinnon wrote: > > On Sun, 16 Sep 2012 18:52:54 +0200 > > Silvio Siefke wrote: > > > >> Hello, > >> > >> can i copy the portage tree from my Notebook to the desktop PC? > > Yes.

Maybe emerge knows to do this on the next run? I haven't tried this way, can someone confirm? One way that works is to uncomment the [gentoo-portage] entry in /etc/rsync.conf on your laptop, start rsyncd, then point your desktop to sync from your laptop with: SYNC="rsync://ip.of.laptop.here/gentoo-portage" in make.conf, and do an emerge --sync / eix-sync as normal.

The samba ebuild doesn't include a dependency on python, so you'll need to do and emerge -t to see which packages do pull it in, but I suspect it is required by an eclass inherited by one of the ebuilds. If so, Samba itself does not need Python to do it's job, but portage needs Python in order to install Samba. that would make it a build dependency which could be uninstalled after Samba was merged, but I'd be nervous about removing Python from any Gentoo system that uses portage. Neil, Looks like you've hit the nail on the head. The media machine has just had a new install of Gentoo done and according to "eselect python list", I only have V3.2. Nothing has been removed, just a few things added so it looks like the default "install" only does V3.2. Looks like I'll have to put up with it, the compile time on the little machine is a killer, and let the install happen. Portage works with either instance of python and its ebuild has "python2" and "python3" USE flags. Alas, the build system of sys-libs/talloc seems to require python:2.6 or python:2.7. I would suggest adding dev-lang/python:2.7 to the world file so as to protect it from being reaped by emerge --depclean, only to be required again for future builds. Incidentally, one of the first things I do on a Gentoo system is mask >=dev-lang/python-3.0 and rebuild affected packages against python-2.7. I have yet to find a single instance where having both installed is helpful. Even major applications such as Django still don't support Py3k. Regarding the increase in compilation time, you could get a head start by grabbing a binary package from tinderbox.dev.gentoo.org. Cheers, --Kerin

Neil, Looks like you've hit the nail on the head. The media machine has just had a new install of Gentoo done and according to "eselect python list", I only have V3.2. Nothing has been removed, just a few things added so it looks like the default "install" only does V3.2. Looks like I'll have to put up with it, the compile time on the little machine is a killer, and let the install happen. Thanks for the feedback everyone, Andrew

Nope, all you should have to do is copy the net-p2p/mldonkey/files directory into the corresponding directory in your overlay. The "2.9.5-execstacks.patch" file might not be needed for the 3.1.x you're building, but it won't hurt anything to leave it there.

And sucks up system entropy. And increases connection latency, if you've already got a request waiting on that fork to spin up. I have StartServers, MinSpareServers, MaxSpareServers and MaxClients all pegged to the same value. And on the server in question, they'll all pegged to '10'. I have MaxRequestsPerChild set to 2, so that any leaky processes get cleaned up. Because I need to fit a lot of operation into a limited space, I need to be able to reasonably predict how much RAM is going to be in use by each of my services. A "MaxClients" of 10 may seem small, but that's what Squid is for; only requests Squid couldn't cache get passed on to Apache. The server I'm describing is a VM with 4GB of RAM, and is also running MySQL, squid and memcached. For those playing with the numbers in their head, each of these numbers reflect RES (code+data resident in RAM): * Each Apache process is consuming 80-100MB of RAM. * Squid is consuming 666MB of RAM * memcached is consuming 822MB of RAM * mysqld is consuming 886MB of RAM * The kernel is using 110MB of RAM for buffers * The kernel is using 851MB of RAM for file cache (which benefits squid). And, not RAM, but potentially of interest for the curious: * The MySQL db is consuming 3.8GB on disk. * The Squid cache is about 9.2GB on disk. -- :wq

So what I think emerge is doing here is installing python 2.7 beside 3.2. When you add the verbose flag to the emerge command, you will probably see something like [ NS ] or [ uS ] at the beginning of the python line. The S stands for new slot, so both version will be installedbecause samba or one of it's dependency is using python 2 scripts. Randolph, You have guessed correctly, I get NS. But to me, the question is why do I even need python at all for something that is a file sharing daemon? I've turned off CUPS etc etc, I just want file sharing to the M$ world, not all the other fluff. I suppose I'll have to have a look at the ebuild to try and work out why this thingy wants Python, any python, in the first place. Andrew

First of all: Python 2 and 3 are (partly) incompatible versions of the language. They can be installed in parallel in different slots (the emerge output will have contained "NS" at one point, for "New Slot"). So you are not so much downgrading python as installing an older version in addition to the current version. Although "older" and "newer" are misleading, since they have both been under active development in parallel since Python 3 was released. Second: you can use the "-t" (or "--tree") option of emerge to get a tree view of the dependencies, so that you can see what exactly is pulling in python-2.7.3. But it sounds like some dependency of samba has a hard dependency on Python 2, so you probably cannot control it. > Any thoughts greatly appreciated, > > Andrew HTH -- Marc Joliet -- "People who think they know everything really annoy those of us who know we don't" - Bjarne Stroustrup signature.asc Description: PGP signature

You've already had a reply about the slotted nature of python, but you also need to understand that USE flags are not dependency lists. USE flags cover optional features, if a package has an option python module, bindings or scripts, a USE flag may determine whether they are installed. But if a package needs python2, no amount of fudging with USE flags will change that fact. -- Neil Bothwick Programmer (n): A red-eyed, mumbling mammal capable of conversing with inanimate objects. signature.asc Description: PGP signature

Samba is not downgrading python, it is asking for python-2.7 to be installed alongside python-3.2 (so you will then have both). Just accept what portage says and let it do it;s thing - there are many packages out there that are not ported to python-3 yet so you almost certainly are going to need python-2.7 at some point anyway. -- Alan McKinnon alan.mckin...@gmail.com

[gentoo-user] Samba wants to downgrade my python....
Hi all, I've got a media server that I'm in the process of installing Samba on. When I do: emerge -NuD --pretend samba I get a list of stuff that portage wants to install, including Python, V2.7.3, even though the machine already has V3.2.3 installed. I've also stripped down the USE variables to basically "server" and that's all and still for some reason portage wants to bring in Python - the older version, V2. I've even added a "-python" to packages.use and it still wants python, V2. I've had a look at the USE variables for the packages that follow Python in the emerge list and they either don't want python or already have "-python" set. Having a play around with equery also didn't reveal anything. Does anyone have any ideas as to what's causing old Python to be brought in? I haven't posted the whole "emerge --info" stuff yet as hopefully someone has come across this problem before. Any thoughts greatly appreciated, Andrew

Apart from that, I should add those files to the dependencies, right?
