Pick your favorite of gzip, bzip2, xz or lzip (I recommend lzip) and then: mount USB-3 /mnt; cd /mnt; lzip * The archiver you chose will compress the file and add the appropriate extension all on its own and tar will use that (and the file magic) to find the appropriate decompresser when you want to extract files later (you can use `tar tf' to test if you want). -- Simon Thelen

I don't have any particularly concrete ideas because the error log isn't very descriptive, but I have several things you can try that will give us more info/may help pinpoint the issue. You might want to post the contents of your /etc/asound.conf and your ~/.asoundrc as well as maybe checking the contents of /usr/share/alsa if there's anything still referencing pulseaudio in there.

Have you > tried it? I have had similar issues, but gcc 6.4.0 isn't the (sole) reproducer. I have 2 systems, a haswell laptop and a Ryzen desktop. Palemoon works fine built using gcc 6.4.0 on the laptop. On the desktop, however, I had regularly occurring segfaults that occurred whenever I ran palemoon and had the ulimit for core dumps set to 0 (ulimit -c to any other value and the segfaults would not occur). I managed to "fix" the segfaulting by compiling palemoon with CFLAGS="-O1" instead of "-O2". I never tried reproducing with an older gcc or clang as the issue only popped up when I rebuilt my desktop for the Ryzen CPU (switched from Nehalem where everything worked fine). Another person I know who uses palemoon on Gentoo has also had no issues with palemoon built against gcc 6.4.0 on an Xeon with Haswell architecture. I assumed this was an issue just with my machine since I could not reproduce it anywhere else. It might be that palemoon has issues with certain optimizations/instruction sets that are aggravated by using newer gcc versions (which could turn on optimizations by default etc). I tried checking when/why the GCC_SUPPORTED_VERSIONS was added to the palemoon overlay ebuilds, but can't find an issue or commit introducing it (didn't spend that long checking), but if I'm not the only one affected by this it might be worth it to open an issue with upstream. > The ebuild from the palemoon overlay explicitly checks for the gcc > version and refuses to proceed if it's newer then 4.9.4. I have > wondered why, but now I know. If you are on Ryzen (or potentially any architecture that isn't Nehalem-Haswell) you could try seeing if it's the same issue I experienced (testing with `ulimit -c unlimited', recompiling with -O1), otherwise you could try out the ebuild I maintain at [1] which may have some differences from the one in the palemoon overlay.

The "caps" useflag controls these at runtime by allowing programs to drop capabilities that the program doesn't need so that if something happens it has the ability to break less things. The "filecaps" flag is the "equivalent" of the suid bit but for specific capabilities (so instead of providing ping with suid-root you can give it CAP_NET_RAW only). It is almost always better to enable both of these where possible since it helps decrease the attack surface for the programs in question. Read capabilities(7) for more information. -- Simon Thelen

Readline is customized by putting commands in an initialization file (the inputrc file). The name of this file is taken from the value of the INPUTRC environment variable.

This will, however, only work on filesystems which support the operation (afaik so far only btrfs). Though other CoW filesystems (such as ZFS) have similar capabilities with snapshotting.

Thank you Neil. I had not seen that link. I've had quite an uphill battle getting Dracut to work properly with a rather strange networking situation I have on a variety of servers.

[gentoo-user] help securing system / remote unlock
Hi – I've successfully set up whole disk encryption by using LUKS and ZFS on top of it. I can boot by unlocking the drive via some remote console. Can't seem to find a tool that will generate an initramfs with support for ZFS, LUKS and Dropbear so that I can remotely unlock the system. Ubuntu makes it very easy to enable Dropbear in their initramfs. I could have sworn I've done before via some popular / existing initramfs tool on Gentoo but can't seem to remember which one (or if it's even possible). Short of building my own custom initramfs or hacking dracut, bliss-initramfs, etc., are there any pre-baked solutions I can rely on? Thanks!

As I > understand it you need to configure the locale on the mail server. IMAP itself does not have a concept of "Trash", the creation of such a mailbox is the prerogative of the client (unless the server itself feels that the imap client doesn't know what it's doing and moves deleted emails into a different mailbox; not that I've ever seen a mail server do that), therefore changing the locale on the mail server won't help and it is indeed something on the client that needs to be changed. -- Simon Thelen

The idea is to create a bridge device, and then bridge the guests tun/tap device with the bridge and your ethernet device. This way they all appear transparently on the network. The net config on that website should be fine for the host, and then pass these command options to qemu -device virtio-net-pci,netdev=hn0,mac="52:54:00:12:34:56" -netdev bridge,id=hn0,br=brkvm You can change the mac address to your liking. -- Simon Thelen

Oh, and even that's not easy. Finding and creating a whitelist that ensures necessary stuff gets done without allowing people to bypass blocks is almost impossible. Getting around these sorts of blocks isn't a matter of theoretical possibility, it's a matter of someone putting in enough time and effort into bypassing it.

The only way to blacklist facebook would be to create a whitelist and drop everything not on said whitelist. If you block DNS, they can use a different DNS server. If you block IP addresses they'll use a proxy/vpn. If you use deep packet inspection they'll use TLS or a VPN or an SSH tunnel. If you can control the systems so that they don't do any of the above, it's possible but you've admitted that you can't (unless you can control all the Virtualbox instances). -- Simon Thelen

Or use partimage/clonezilla like Neil mentioned which does all that automatically. For my part, I found compressing all files using squashfs to be most useful, specially for backups as restoring single files vs all files is just as simple. Also, using the squashfs archive as read-only base of a unioned mount (aufs, unionfs) is also a very useful trick. As my systems are all setup the same, I never backup the partition table and recreate it each time (easy, and I often change the partition layout anyway). Simon

Hi Helmut, Sorry for the problems. No real good ideas here, but assuming the Win 7 VM is on the same Gentoo machine then it appears to be something missing from Gentoo. I'd start by using the Win 7 disk tools: Control Panel - System Security - Create format hard disk partitions and look to see what Win 7 believes it's talking to. Also, make sure if you have the VM running that it isn't automatically mounting the Garmin which would make the SD unavailable to Linux. Handle that in the Virtualbox-Device menu. Best of luck. Sounds like an interesting problem, if that's possible. Cheers, Mark
Re: [gentoo-user] I want to play movies without hangs
Also, there was a thread a good while back with this issue and their fix was to do a emerge -e world with everything optimized for their CPU and such. May be worth thinking about at least. Video playback and CPU optimisations go hand in hand. One video I have had for a long time, I could never play it at all on any of my computers and I could not beleive what I saw next... I got a new PC and thought to give it a try. It worked painfully, skipping and using 100% of one of my CPU cores. I was sad and thought this video might have been corrupt. After a wave of cleanup, I had removed all CPU optimisation flags from my make.conf (I was originally negating many, like -sse, etc, so I left it to my profile to choose what was needed) and recompiled everything. After that, the same movie played in the best quality I had ever seen and CPU usage was below 5% I was even able to open 12 movies (4x3) all playing at the same time (this was unthinkable before I optimized my system). Anyway, keep in mind that my particular starting scenario was that I had un-optimized it long ago! Good luck!
Re: [gentoo-user] Any experience with swapfiles?
I haven't used a swap partition on any of my systems (intel celeron, p3, amd64, intel xeon) for over... what... 10 years? Swapfiles only, and sometimes I don't even mount the swap. Although I have never removed support for any kind of swap from my kernel. dd if=/dev/zero of=/path/to/swapfile bs=1M count=1024 mkswap /path/to/swapfile swapon /path/to/swapfile (btw, I like to put the swap file in /root or /boot, but that's my pref, on space constrained PC, i would put a swapfile on every drive to distribute it). I don't have access to my box to confirm but I think /etc/fstab would be setup the same as normal swap except with the file path instead of the device partition. Except for issue pointed out by Paul about hibernation, dd line above takes care of non-sparsity. As for security, having a swap is less secure than having none: a malicious persion could extract information from programs memory which was swapped (ie, like the decripted information for your eyes only). Having no swap at all was a problem on small systems with little RAM when emerging big stuff (boost failed all the time on a pc with 256mb). Resizing swap on-the-fly with swapfiles: And on HDD-space constrained system, i used to have several swapfiles that I created and deleted in the manner above, that I named swapfile-256, swapfile-512, etc... A smooth upgrade of swap on-the-fly was done this way: say I had 256 swapped on, I could swap on a new 512 (768 total at moment, all data still on 256mb file), then swapoff the 256 (takes a bit of time for swap data to move over), delete the 256. Downgrade can be done in the same manner. swapon -s (status) will be a good friend of yours now. Good luck!

Any downside to using a swap file instead of a swap partition, maybe depending on which filesystem you use, or something? Security holes? Any horror stories out there?
Re: [gentoo-user] 3.2.12 Kenel wont boot
The error just means it cannot find any device called /dev/sda4, but can only find your CD (sr0). I get this when booting from a usbkey and I need to tell the kernel to wait 5-10 seconds before detecting hdds. I also had this error when I used a config from my normal computers onto an older computer that used IDE and PATA (these were disabled in kernel). Good luck!

Re: [gentoo-user] Tips for saving power needed...
There's powertop that I use, which shows a listing of things that are keeping the computer busy. And it gives recommendations on how to lower power usage (including setting kernel options, enabling/disabling stuff in /sys, etc...). It also estimates power consumption in Watts and gives you approx time left. Many recomendations already posted in this emails will be suggested by powertop.

So I need to find a way to save at least those 15W, or I will be moved to higher tarif (which means higher costs for server-housing). Before going hard(ware) way, I would like to try first all possible software solutions. What I tried up to now is cpufreqd, CONFIG_NO_HZ=y, and spindown. In addition to that I adjusted fan-speeds to a little lower values and turned off some unneeded peripherials (in bios). Is there anything else I could do? Any tips would be greatly welcomed... Jarry I'd rather have *more* RAM than causing unnecessary swaps. Try using a smaller swapfile to reduce swap tendencies. You can always push a larger swapfile into service when needed. There's also a kernel knob to set 'swappiness', but I forget what exactly. Try 'sysctl -a | grep swap' Swappiness is the knob you want to set if you want to reduce swappiness. I set mine to 0; swap only when absolutely necessary. In /etc/sysctl.conf: vm.swappiness = 0 On the command line: sysctl -w vm.swappiness=0 -- :wq
Re: [gentoo-user] InitRAMFS - boot expert sought
Then copy /usr over: mount -o bind / /mnt mount -o remount,ro /usr cp -a /usr/* /mnt/ The bind moun t makes the root FS appear in a 2nd place, without /usr being populated by the content of your /usr partition. Don't forget to remove /usr from /etc/fstab. I can recommend using rsync instead of cp. Main advantage is rsync can be stopped (ie. killed) mid-way and resumed later. No big deal, but if your /usr is as large as mine, you might like this! If transfering very large files, instead of restarting the large file from scratch, using the --append option will write the partial data in the destination file. If killed and resumed, rsync will find the dst file is smaller than it should and will continue from where it left. If the data is absolutely crictical important, you can also use the -c option to force rsync to do a checksum of the files to compare, it will recopy anything that's not right. I normally use a -c check if I used --append and had to kill it (because I'm paranoid AND patient). Although I have seen zero cases where the -c found errors. Note the slashes at end of directories mean something with rsync, in my example below, it means make usr and mnt identical, having rsync /usr /mnt/ means copy usr into /mnt/ (giving /mnt/usr/). So cp -a /usr/* /mnt/ becomes: rsync -ah --progress /usr/ /mnt/ Enjoy!

This increases the number of Gentoo systems I'm responsible for and they're nearing double-digits. What can be done to make the management of multiple Gentoo systems easier? I think identical hardware in each system would help a lot but I'm not sure that's practical. I need to put together a bunch of new workstations and I'm thinking some sort of server/client arrangement with the only Gentoo install being on the server could be appropriate. - Grant I've been managing 3 very very different gentoo systems for more than 12 months now. I used to have 2 more machines but I decomissioned them for they were old and noisy and it's summer and it's hot enough like that! haha I do not have a lazy-proof way of administrating this whole stuff, but I've come up with some kind of methodology that helps... I found it really helps to have the same profile on all machines, same /etc/portage everything. The /etc/make.conf can vary, but I would make it vary in the most minimal way. For example, all my kernels and /etc/make.conf are compiled for an i686, global use flags are exactly the same... in fact the only difference is my host has extra make option -j5 and their distfiles mirrors will point to my own computers. Basically, downgrade all computers to the lowest common denominator of all your computers. I don't use binpkgs but I'm working on that... and also for the world file, I have 2 world file styles, one has everything in it and the other is just the minimal stuff. I used to maintain the world files directly but I've opted for creating 2 ebuilds in my own portage overlay which are basically called sys-apps/everything and another called sys-apps/minimalist. Maintenance of world files moved to the maintenance of these ebuilds. Also, it helps to have your faster computer install all packages that would be installed on the others. If there's any trouble doing the emerge on that one, you'll have the same problems on the others. If the solution was to add some keywords in /etc/portage or something like that, then you can copy the change over to your other PCs and their emerge should be fine. To reduce network load, I sync my master server (my server online) against official sync server, then I sync my main computer at home against my server, then I sync any other computers at home against the main computer at home. But the activity of making your systems up-to-date will vary in intensity depending on how well it goes. When things are fine, it used to take 30 minutes to get all my systems updated, with the slowest ones taking 2-3 times that but requiring no intervention until the end. I'm currently in the process of writing a script that fully automates the update process. It basically tries things like emerge -uDN --keep-going world and checks for errors, if there are, it then fires a few safe responses which have helped in the past. For example, if the above emerge fails, it then tries a revdep-rebuild, an lafilefixer, python-updater and a few more, and then it restart from scratch trying the emerge again, over and over. Rarely, this will not work and will require that I mask something, add some keyword or update my ebuild to get rid of some package. The script is clearly not intelligent and is wasting a lot of time, but it eventually gets it done. Upgrades now take at least 1 hour, but are fully unattended. Also, I think Wonko's suggestion is pretty good in combination with my suggestions, I haven't tried but it does seem very attractive. Simon

I've read about this kind of setup when I was interested in RAID long ago... Now that I know my hd is actually on a raid, maybe i could benefit some I/O performance improvements by tuning this a bit! Anyway, I was told by the support team that another user on the same physical machine (remember it's a xen VPS) was doing I/O intensive stuff which could have I/O starved my system. I don't understand how starving or even doing some kind of DoS attack could lead to a complete freeze on the console, but eh... They offered to migrate my system to another physical machine, and after that... I was able to perform a complete 'emerge -e system' in one shot without a scratch, I even did it with --jobs=2 and MAKEOPTS=-j4. After that, I started a complete emerge --keep-going --jobs=2 world with MAKEOPTS=-j8... (i got 4 cores: dual xeon 2Ghz) This last emerge is still going on as I write this and is emerging pkg 522 of 620 !! And there were no build errors so far... It's emerging glibc at the moment, so once the big emerge is finished, I'll probably recompile all pkgs that depend on glibc.

My root device is /dev/xvda to give you an idea... But I did run an fsck, a pretty thorough one like fsck.ext3 -c -c -f or something like that... I also added another option that made it super verbose, so I don't know if anything was found, just that *filesystem was modified* by it... I just did the following emerge, these packages had not been recompiled by the emerge -e system that crashed.

Ok, was just doing a fsck.ext3 -c -c -C 1 /dev/xvda from within a

So I guess Gentoo is not responsible after all... I've opened a

[gentoo-user] Intel dilemma
I posted this on the forums but I want some more information. I have a bit of a dilemma. With these settings, xf86-video-intel: 2.6.3-r1 xorg-server: 1.6.2-r1 and 1.6.3 kernel module: i830 kernel: gentoo 2.6.29-r5 and 2.6.30-r4 sometimes when stopping or starting X my computer would freeze and there would be no video output. However, other than that, inside Gnome Firefox ran pretty smoothly, not incredibly fast, but not sluggishly at all. With these settings, xf86-video-intel: 2.8.0 xorg-server: 1.6.3 kernel module: i915 kernel: vanilla 2.6.31_rc7 X starts and stops very smoothly without ever freezing, I think because of the KMS. But Firefox runs sluggishly and my whole machine freezes in Firefox frequently. According to this, http://www.x.org/wiki/IntelGraphicsDriver, the 2.8.0 driver drops support for XAA and EXA, but has no UXA support for my graphics card (865G), so I think I'm getting no 2D acceleration. Could that be the reason Firefox is so slow? As for the freezes, I think that's just because the newer driver is unstable. What are the optimum driver and kernel versions for my graphics card, the 865G? Also, the reason I'm using the 2.6.31 kernel is because that X.Org wiki page says it works best with the 2.8.0 intel driver. Oh, and what exactly is the kernel module for and what are the differences between the i830 and i915? Pappy told me I should use kernel .27, and that KMS support right now for my card is very unstable. Anyway, I just want to know the best options right now for my card which is the 865G.

As my box is ~x86, I have installed many versions of xorg-server without varying the kernel and driver, and they worked all right. I am thinking in giving up to using the intel driver in order to user the latest kernel, with an /etc/X11/xorg.conf using a VESA card configuration and I have not tested the i830 option. Hope this helps. -- Andr??s Thank you very much! That is very helpful to know and I will get back to you on how it works for me. Also, let me know how the VESA card configuration works.

Re: [gentoo-user] Intel dilemma
Hey, nevermind about my USB wireless-LAN card not working, it just requires a different firmware for that kernel, I looked it up (although the problems with it hanging still remain). By the way, I know I should be replying to the messages I already sent right? But those messages don't appear in my inbox, with mutt using GMail and IMAP, any suggestions?
Re: [gentoo-user] Intel dilemma
Well I tried the .28 kernel with the package versions you suggested, and when the X server starts, it's just a black screen BUT the machine doesn't freeze and there is video output, it is just black. These lines seem relevant in the Xorg log: (II) GLX: Initialized DRI GL provider for screen 0 (II) intel(0): Setting screen physical size to 304 x 228 [config/dbus] couldn't take over org.x.config: org.freedesktop.DBus.Error.AccessDenied (Connection :1.3 is not allowed to own the service org.x.config.display0 due to security policies in the configuration file) (II) config/hal: Adding input device ImPS/2 Generic Wheel Mouse One other problem I have with that kernel is that my USB wireless LAN card isn't seen, even though I have the correct prism54 module set in the kernel, like in my new kernels where it works fine. By the way, if you choose prism54 built-in, for some reason the kernel stops early in the boot process for several minutes before continuing. Should I file a bug? Do you have an xorg.conf?

Now my graphics are definitely faster, but not as fast as they once were before I upgraded to the 2.8 intel driver series. For instance, Facebook.com on Firefox is much slower and laggy. And I've noticed it even in apps like mutt and less in gnome-terminal. I haven't experienced any freezes though, and the way it was before, it *definitely* would have frozen by now. So any thoughts on why it is slower? Do you think it will be faster in subsequent releases? I thought uxa was supposed to be better than whatever I had before.
Re: [gentoo-user] Intel dilemma
Yes, it's me again. I think upgrading to the newest unstable vanilla-source (31-rc8) makes it definitely go faster, but Firefox is still a little laggy. Although Epiphany really isn't, so I think it's just Firefox's fault. Anyway, my computer actually did freeze once. Just wanting to provide an update I guess.

Re: [gentoo-user] Blank screen when starting or stopping X server
Well I think I fixed the problem by upgrading the kernel to vanilla-sources-2.6.31-rc7 and xf86-video-intel-2.8.0 (and recompiling against the new kernel), and switching to the i915 module in the kernel. I did this because of the suggestions at http://www.x.org/wiki/IntelGraphicsDriver (I already had xorg-server 1.6.3). However, now firefox is significantly slower and I'm wondering if that is a problem with the newer driver or the framebuffer or something. Is that possible? Or should I rebuild firefox? Another thing is that in menuconfig, there was no longer an option for the framebuffer driver for my chipset, but after openrc starts the boot process, the frame is suddenly buffered. How does that happen?

[gentoo-user] Aluminum iMac framebuffer?

Re: [gentoo-user] File synchronisation utility (searching for/about to program it)
I'm the last you would want to give advice about this question, but even though I am not a programmer, I have been using git to sync on three different systems. I am using a flash drive as a cache, so to speak. I followed some tips from the Emacs org-mode mailing list to get this going. It wasn't simple for me to recover when some files got out of sync on one of the machines, but it was simple enough that even I could figure it out. I used a bare repo on the flash drive and push from each machine to this, a very simple procedure that can be automated through cron, and pull to each machine also from the bare repository. I am not syncing a programming project, but my various work. Your reply is more than welcome! I have tried using git in the past and found that it doesnt work in my 'space constrained' scenario. The need for a repository is a problem. The use of the usbkey however is nice since it allows git to work without having each computer maintain its own repository... but still... i dont currently have a usbkey that's large enough to hold all my data, even if i could compress it i doubt it would fit. Another thing is, i wonder if it retains the attributes of the file (creation date, mod date, owner/group, permissions)? As this can be important on some aspects of my synchronisation needs. Still, git is a very good solution that works incrementally in a differential manner (makes patches from previous versions). But when i tried it, i found to suit my needs it would require the programming of a big wrapper that would interface git to make some daily quick actions simpler than a few git commands. Again, I am the least clueful you will find on this list, but if you wish for me to tell you the steps I followed, that is possible. One of the mailing list threads that got me up to speed relatively quickly was at this link. (Hope it's ok to link another mailing list from this one.) http://www.mail-archive.com/emacs-orgm...@gnu.org/msg11647.html I'll check it out... since i have my own solution all thought of and designed, i'll be able to compare it and re-evaluate git from a new angle. As far as i can tell, there is no rule against links, but i think there might be against publicity (ie if the link was to your business product that fullfills my need). I apologize if the existence of a bare repo as an intermediary is a problem. This can be done on a server as well. It is... it makes all my computer dependant on that repo... sync'ing computers at home can be done alright, but will still require walking around pluging/unpluging. Makes this practically impossible to do over the network (or to sync my host on the internet, not all my pc are connected to the internet so the repo cant be just on the server, i would have to maintain several repositories to work this out...). It may be possible to adapt it to my scenario, but i think it will require a lot of design in advance... but i'll check it out... at worst it will convince me i should program my own, better it will give me some good ideas or fortify some of my own good ideas and at best it will be the thing i've been looking for! Thanks again! Simon
Re: [gentoo-user] Re: File synchronisation utility (searching for/about to program it)
...I am using a flash drive as a cache, so to speak... I recently learned that flash drives wear out after about 10,000 write operations, which came as an unpleasant surprise. Just be aware that you are drastically shortening the life of a flash drive by writing to it frequently. (or so I've read) I think the problem is the number of erases actually (but you erase in order to write, so)... This is number really is more or less, some companies achieve higher number of writes, i think this figure shows a worst-case scenario. Also, it's actually 10k writes per sector... git, as far as i understand, will append new versions to the repository, so it's writing on other sectors and only once. Only if you remove, prune, cleanup the repository, then it would erase... and if you were to format it every day and write to it once a day, (say one new write per sector, on every sector, once per day)... i've quickly calculated the key will last around 27 years. I'll be glad to buy a petabyte usbkey for 10$US in 27 years man! lol Simon
[gentoo-user] File synchronisation utility (searching for/about to program it)
of a given conflict to always resolve it this way. This could effectively help in having some files mirrored from A-B, some others mirrored from B-A, some others to be backed up before being overwritten and some would always require user interactivity (like my current project's file)... This is a matter of preference and any utility that dont understand this works against me. No tool i've encountered supports this, unison could do some of these but i would have to break the sync'ing process into multiple smaller syncs, and most tool will just shoot a list of all conflicts and as wheter to keep local, keep remote, ignore, cancel, and this for each and every conflict (the list is long, the cancel option is tempting!). -Friendly config/maintain: I have the friendly user in mind (me), meaning the tool should be user-friendly! User-friendly doesnt mean graphical interface with lots of eyecandy (this makes people fat, it's hostile to me, not friendly at all!). However, I like to have only one config file to edit for all my needs, or a directory containing one level of files, a few files, each logically separated (think about /etc/portage) and most of all documented, intuitive. These are the features i need most. I am tired of 'working around' limitations or missing features. I am tired of having to do multiple syncs to get my whole house up2date. And finally, thanks to those that were interested in my post enough to read as far as here (unless you jumped straight here, but thank you still for taking the time!). I'm desperate at creating a project that will be useful to me and hopefully to others too. I'm a very good C/C++/PHP/JS programmer but i could only rarely find work in that field since i have no diploma (highschool diploma from 10 years ago that's all). Due to some illness i've lived a terribly unstable life and i've had an exploratory tendency in development, meaning i've started about 10K projects, but finished none. I have published nothing so far... in other words, i am nobody, and for companies, i am a risk, even if i ask half the usual salary it's still a division by zero: salary divided by zero credibility (ie no diploma and no work xp). If i can build this project (on my own for the start) and publish it, i think it would help me a lot professionally. Also, once the first version is out, i'll clearly welcome patches from the community and having a team work will help even more. Also, very important to note, i am currently unemployed, collecting unemployment insurrance as income, i still have about 2 months left of free time to get my professional situation back on track, this 2 months of my expertise is more than enough to get a good stable beta version of this project. But i need to get it started, i must be convinced this is the right choice. Thanks for reading, hopeful to be reading your answers! Simon
Re: [gentoo-user] SSL giving corrupted MAC on input

Well, since all my problem were related to the use of ssh, i did a full: emerge -e openssh (took a 2 days on that super old pc, while shutdown for the night) I tried doing an full update after: emerge -uDN world emerge --depclean revdep-rebuild Then i tryied copying files through ssh and got same issue again. I also tried with a usb adapter, got the same issue. Again, i remind i tried transfering without ssh (ie using http or netcat) and it works top shape. I'm running memtest86 on that pc at the moment, i will look more into the flags (i havent checked in the /etc/portage/packages.use, there might be some sse in there too that i missed). Since this pc is not connected to the net, i used to sync it through ssh, so it has not been sync'ed in a while now... i'll try to manage to sync it (maybe tar /usr/portage and netcat that over, dunno...). I'll post again with results of these last few checks later today... Thanks!

[gentoo-user] SSL giving corrupted MAC on input
Hi there! I'm getting this issue where even very small transfers through ssh will cause this error message: Corrupted MAC on input. I've done my homework and found out this is not necessarily related to the network hardware as TCP would retransmit such corrupted packets, moreover the error message is clearly related to ssh as googling proves this. A quick troubleshooting i've done was to setup apache and simply wget a very large file over plain HTTP. Transfer worked, i did it a second time and diff'ed the two downloads, they were the same. I then did the same test over HTTPS and got an error (SSL3_GET_RECORD:decryption failed or bad record mac). This clarified the problem is much more related to SSL than anything else. A quick glance at `emerge -vp openssl` showed an issue: it had been compiled with sse2 support while this computer's cpu didnt support that. Changed use flags and recompiled, restarted ssh and apache. They both continued giving the same error. I finally rebooted the machine, in case, but same issue still... The only use flag for openssl now is zlib. What is also pretty strange about the issue, is i haven't touched the kernel in a long time and i usually do all my gentoo updates on monday. The problem must have happened since last monday's updates, but i dont monitor those very much, all i care is everything went fine and that revdep-rebuild says i'm good to go. I've done many emerges since then so i cant figure out a way to see what has been updated recently. A bit of background: That PC runs kernel 2.6.24, it's my slowest pc (used for backups mostly) P3 @ 450Mhz, it's got 128MB of ram. Some programes have been unmasked, but none that have any relationship with openssl are, everything dealing with that is stable. Doing `find /usr/portage/distfiles -ctime -10` (should give me the files downloaded within last 10 days, right?) it shows a few files but glibc is the only that i can see has relationship with issue... Anyone can help troubleshoot some more?

Re: [gentoo-user] sync'ing two computers (not related to emerge)
Issue is resolved (solution below) An unstable link is probably triggering your issue. If the link dies and comes back, unison (at least version 2.27.57, what I have here) gets confused and just sits there. What's interesting is that if unison is killed on the initiating machine, the remote process stops as well, which leads me to believe this is a bug in unison; they can talk, but they don't do anything. I've glanced at the code before despite my lack of familiarity with OCaml, as my wireless connection will often die, causing much grief, but I've never found a solution. The problem was actually related to ssh... setting those in sshd_config fixed it: ClientAliveInterval 15 TCPKeepAlive no --- The TCPKeepAlive option set to yes doesnt seem sufficient, it was suggested by someone to use ClientAliveInterval instead. (or on the client end i think you could set ServerAliveInterval) Thanks all! Simon
[gentoo-user] union merge for binpkg makers
Hi there, i've been using my host online to compile updates for like the past year or so... My host is currently configured so that its world file is the combination of all my PCs at home's world. So the host has x11 installed and lots of other completely useless stuff for a remote host! I decided to start a small project, but i wanted your opinion before doing so... also, i dont want to reinvent the wheel so if anyone thinks of a better way to do this or if there is one already in use... let me know! I'm using a host (or binpkg cruncher) to make all emerges as the host is approximately 10 times faster than my fastest PC here (they are very old). Even when distcc is setup perfectly, the host still wins the competition, by far. So i make binpks on the host and propagate them to the PCs at home where i emerge using the -k option. (a few rare packages will still have to be re-emerged, but that's normal) To facilitate reading: sum(worlds) == all PCs worlds combined Also, this works only if both host and pc would create the same binpkg (having the same make.conf options mostly, same stuff setup in /etc/portage, etc...) Right now, here's the base of the process to get one PC updated (without my unison world): host emerge --sync host emerge -uDN sum(worlds) [builds binpkgs] sync host's portage with PC's portage PC emerge -uDN -k world - Here's the process ( a bit more complicated ) using unionfs: host emerge --sync host emerge -uDN world start unionfs over the whole root and chroot in union mount point host emerge -uDN -k sum(worlds) exit chroot host rsync -ah --progress /path/to/rootunionfs/usr/portage/packages/* /usr/portage/packages/ host rm -Rvf /path/to/rootunionfs sync and emerge on PC as with previous method You'll notice the emerge run on host, inside the union uses the -k option, this is to help the host and avoid recompiling dependency it had compiled in the past but had not really installed. This way, it quickly installs all dependencies in the unionfs, compiles them if necessary and builds the binpkg for every emerge. This process will take longer that my current process, but should help maintain a clean host. It could even be possible, if i dont suffer from disk space constraint, to keep the unionfs and just remount it correctly for the next emerge, but this could lead to some issues (ie if i emerge something outside the unionfs at some point, etc...). What do you think? Should i start working on this? Or is there anything better out there? Thanks, Simon
Re: [gentoo-user] union merge for binpkg makers
Storage space comes pretty cheap these days, so prehaps it's just easier to get dirt-cheap 80G harddisk and build (and keep) all the packages from sum of the worlds on it in a dedicated chroot or VM? Well, i'm keeping all packages currently, and diskspace is cheap for home computers, but not on this binary cruncher... =( To sync world, make.conf and /etc/portage you can easily use distributed VCS like git or mercurial, keeping each host's files in separate branche on this server. It has added benefit of keeping all the history of your configuration, should you need to fall back to some stable state. Also, it's much easier to sync any changes in any way between the hosts that way. Good idea sshfs (prehaps with something like funionfs if you keep local packages too) should be enough to mount generated packages to any host and deploy them. To avoid unnecessary syncing of portage trees (even with one local server) you can just mount it when needed, along with the packages, since it doesn't need write access anyway. Well i used to use sshfs to mount the binpkg repository's /usr/portage... but running a basic `emerge -k -vp -uDN world` would take days, the -k was the problem. So, i now sync the /usr/portage from my host to one of my PC, then sync from that PC to the others locally. Then i emerge. Also, i dont fully like having my packages remote, i like to be independant... so NFS and others may be a neat solution, but brings a lot of limitations in my situation. Thanks!
Re: [gentoo-user] Moving an installed system to RAID10
Or you can create raid0 with partitions on both drives (sda1+sdb1) and mirror it on the second set of partitions on the same drives. But then you do not have any protection from total disk failure you'd normally expect from raid1. Only some very little protection against a sector failure. Plus two equally strange configurations where you first create raid1-mirrors and then strip them to raid0. Doing raid10 (or raid01) with only 2 disks is imho not a good idea... It is very well written everywhere that deals with raid that it is a very bad practice to have more than one raid device per drive AND per bus. Having two identical disks and a need for redundancy calls for raid1 (mirror), nothing else. Or anything else is just fancy crap, but hey, you can learn a lot with fancy crap. If you wish to get something a little more than raid1, it might be with raid6: partition each drives in 2 equal sized partitions, then create the raid6 on those 4 devices. You loose both reading and writting performance due to seeking from one partition to another, but you keep redundancy since with raid6, 2 device failures can happen. The advantage here, is scalability: you buy a third drive later, partition it correctly and 'grow' your raid6 on those 2 new devices. But even then, if you buy a 3rd drive, i'd recommend raid5 simply on the whole disks (well one partition per drive). Here, do whatever scenario you want, and when you buy a 3rd disk: fail and remove the secondary drive on current raid create a raid5 with the new drive and the removed spare and 'missing' copy old raid over to new raid fail old raid and add its device to the new raid update your /etc files to point to the new raid Enjoy!
Re: [gentoo-user] sync'ing two computers (not related to emerge)
How long is unison taking to check for changes? I can usually reconcile changes in my home directory (approximately 45G, 125,000 files) in less than 10-15 seconds between my slow laptop drive and a remote machine. However, if you are syncing with a Windows machine, expect the sync to be much slower. Fast checking is not safe on Windows, as unison can miss changes, so it scans every file every time unless you tell it otherwise. Ok i had to try a few times and now with tcpkeepalive being turned on it doesnt disconnect. But when the scan is done, it 'reconciles' the changes (so it has received the changes from the remote end) and Begins the transfer of a dozen files, but not a bit is transfered. The sshd and unison process on the remote host are waiting/sleeping or in coma, but nothing happens. I just tried again and let it sit on the transfer to see if the processes would wake up, but it read from remote host that connection timed out. I'm not sure but this may be due to the fact i'm on an unstable link... I'll try once more with a ssh session on the side to see if that session will get disconnected or not... It would be so nice if unison could 'remember' the changes on my HD against its local archive... anyway... Thanks, Simon
Re: [gentoo-user] sync'ing two computers (not related to emerge)
http://www.linuxjournal.com/article/5976 http://kitenet.net/~joey/svnhome/ http://www.google.com/search?q=homedir+version+control Hey thanks Stroller, I'd be interested in these solutions, but i dont have enough space to copy everything in double (keep a backup). So what i do, and this is why i need unison, is that my older computer is the backup of my newer computer. Only a few files here and there are not copied over (those that are computer specific). But your idea was very good and I'll keep note of it... I'm thinking on buying a hard drive as soon as it becomes possible (unfortunately in my situation, this may not happen until a few more months) and when i get that, I'll set it up as a central repository (if i havent' found any better solution until then). Thanks!
Re: [gentoo-user] Moving an installed system to RAID10
I know I'll need to change /boot/grub/grub.conf, /etc/fstab and any other
files that refer to my current drive partitions, /dev/sda{1,2,3,4}. I am
concerned whether my current kernel will recognize the /dev/md{1,2,3,4}
arrays on booting, and before switching from the initrd root disk. How can
I
check the parameters and contents of the initrd I'm currently using and/or
generate a new one to permit booting from the RAID disks?
On my eeepc I use raid a lot (i bundle old usb keys together, dont laugh!)
I dont use initrd and here is a typical grub line with my raid:
(hd0,0)/boot/bzImage-2.6.29.1 root=/dev/md64 delay=10
The delay is useful to give time to the kernel to recognize my usb keys
before loading init.
Make sure the partitions are 'fd' type in fdisk (raid autodetect or
something like that)
One important thing: the kernel that gets booted from grub (the bzimage) it
is best when it is sitting outside the raid since grub does not support raid
(iirc). So, back to my example, (hd0,0) actually is a ext2 (not raid)
partition.
Good luck!

[gentoo-user] sync'ing two computers (not related to emerge)
hi there! I've been using unison to synchronise and backup my computers. unison is based on rsync IIRC but with the difference that it 'remembers' the state of the folder that was synchronised. This way, if I delete a file on A, when sync'ing it will be deleted on B. While rsync would leave the file on B... I see rsync as a very good 'cp' program, but I need something that can deal with conflicts (file changed on both hosts/directories) and can propagate changes like deletes properly. Is there a way to get this behavior with rsync (maybe i missed something)? The reason i'm asking is that unison has been having problems recently in sync'ing two pc... On my laptop, when i start the sync, it first checks it for changes against the 'unison snapshot'. Changes done since last sync are those that will be propagated. But it takes so long to check for changes (disk input rate is too slow i think) that once it finished, when it's time to send the changes to the remote server, the remote end has already disconnected! Thanks for the help/suggestions!
Re: [gentoo-user] sync'ing two computers (not related to emerge)
If you are using ssh with unison, are you using the KeepAlive yes option in your ssh configuration? If not, add it, and your connection should not close from inactivity. If you are using direct sockets, unison will use a keepalive so it can timeout if the communication link is broken. Well i was using it, but i found out the option was commented out on my host's config... i set it to yes and trying again now... will have results in a few mins How long is unison taking to check for changes? I can usually reconcile changes in my home directory (approximately 45G, 125,000 files) in less than 10-15 seconds between my slow laptop drive and a remote machine. However, if you are syncing with a Windows machine, expect the sync to be much slower. Fast checking is not safe on Windows, as unison can miss changes, so it scans every file every time unless you tell it otherwise. Well, the problem seems to be with my /usr/portage that had not been sync'ed for a long time (i guess it has to make thorough difference checking?). So there is lots of files to check. It really takes minutes to scan for changes, i'm timing this run, if it fails i'll post how long it takes to do the whole scan until it starts transfering and finds out it got timed out. Sync'ing is done from linux to linux. The problem is really hardware related; i'm thinking on getting a new portable HD, but since i'm about to loose my job,i might want to wait! ;) Thanks!
Re: [gentoo-user] GPRS connection through usb
You do NOT need PPP, but you do need a fairly recent kernel (= 2.6.27 at least, not sure of the details). You need at least CONFIG_USB_RNDIS_WLAN as m or y. With udev and 'm' things work mostly automatically on the linux side. On the phone you enable advanced networking (or else you will see the phone as ttyUSB? and you will need ppp). This is done, no prob. Then you plug in and run dmesg -c until things quiet down. You should see a new eth? interface. Enable internet sharing on the phone, and you should see in dmesg -c that your new ethernet interface disappears and reappears. If it does not reappear your kernel is too old. doing `ifconfig -a` only shows the interfaces that were there before, no changes here. the dmesg output contain USB debug info, but nothing about interfaces or networking. I believe I'm missing another kernel config somewhere? Btw, this is with 2.6.29.1... Thanks!

On my gentoo box i can now start the interface like a regular ethernet interface. I have a debian box with a kernel from unstable where dhcp fails on the phone 'ehternet' device, so I have to do ip addr add and ip route add manually to get the network going (somehow the ifup command on debian prints the assigned ip and the gateway ip, gut does not configure the device properly). Do some googling to fill in the details, I'm not using this regularly. Wow, thanks for the clear and thorough reply! I've recently upgraded to kernel 2.6.29.1 (i used to have 2.6.24 with several external drivers) so i should be fine. I'll give this a try asap, but since i have a day off tomorrow, i might do some fiesta tonight, in any case, i should reply soon with success or failure! Thanks again! Simon
[gentoo-user] [slightly OT] Pocket Putty or similar
Hey guys! i just got my internet connection working through a new cellphone (pda). the connection works fine but is a battery eater (i share the cell data connection to wifi, and then from the pc connect to the phone's ad-hoc ap, very cool, but have the charger handy!) Anyway, I've come sometimes to the point where i need to do some very minimal work on my linux host running gentoo but from the cellphone. I've downloaded pocket putty (i have lots of respect for putty, it's probably the only windows app that I dont despise even unconsiously!). but it's not very good for my use, since I have to send a Large numbers of Ctrls-keys combinations, and seems the meta key is not supported... working in emacs is either very painful or simply impossible. (How am i to survive now that i cant type: M-x doctor ?!) Anybody got a suggestion of a software to use on the pda to access my host and have a nice terminal (ie maybe be able to bind keys arbitrarily to some character?) Thanks!
Re: [gentoo-user] Software RAID vs Fake RAID
The only reason I considered the motherboard RAID was that I could have an XP partition and install an ext2 driver to access my Gentoo partitions. As far as I know, a filesystem in a linux software raid cannot be accessed from windows. After reading the replies here, I'm going to go ahead with linux software raid. Accessing my linux partitions from windows isn't very important for me, as I only use XP for occasional gaming. And even then last time i checked windows support for ext2 FS wasnt so great. I personnally do all file transfer using linux (which works fine with windows' fat FS, i dont use ntfs because it used to lack write support long ago). That is, in windows, i would move the files in a folder created on the desktop, and then in linux, i would mount the windows drive and copy/move the files in /mnt/windrive/Documents*/simon/Desktop/folder_for_linux/. If you wish to setup windows on a raid, you might consider the fakeraid for that? But if you use it for gaming i dont think raid is advisable, doing backups should be sufficient, IMO. HTH, Simon
Re: [gentoo-user] [slightly OT] Pocket Putty or similar
Hey guys! i just got my internet connection working through a new cellphone (pda). I think we'll need to know which operating system(s) the phone runs in order to suggest anything. Makes sense! Sorry that i forgot! The phone is an HTC TyTN (also known as Hermes100, i think). It is running windows mobile 6 pro (i wish there were a good gentoo mobile! ;) Processor: SC32442-400mhz Screen is 320x240 I havent setup anything on linux to share anything with the phone. Neither in windows but i'm probably going to install activesync on my winxp pro pc. (eventually going more and more using only linux stuff when i get everything working). Thanks
