So I think in your case it should be much faster than that! you are comparing apples with oranges (harddisks with moving arms with solid state devices). Do yourself a favour. Look up how long a harddisk needs to position its head. Now you can calculate how many times a second a harddisk can position its head. Now remember: swap is stupid, so lots and lots of head movement needed (and a cash flush is running too - so even more movements to write all that crap to disk), The result: the whole mess is fscking slow. You can have a nice fat raid with nice and fast harddisks - if you try to stream to a 15 year old DLT drive with 5/10mb/sec speed the dlt drive will constantly rewind - because harddisks suck when they have to seek. And swap (just like a backup) = lots and lots and lots of seeks. That reminds me of how SSDs ought to be much faster than hard disks. But every time I use my Acer netbook (8G SSD) I curse and swear and commit random acts of violence - that first gen SSD controller is the worst possible thing to ever hit computers. I swear the 4G SDHC expansion card is leaps faster (completely OT, I know. I'll keep quiet now.) -- alan dot mckinnon at gmail dot com

Re: [gentoo-user] mysqld invoked oom-killer
On Thursday, July 21 at 16:53 (-0700), Grant said: So swap isn't treated exactly like RAM. It actually has special handling in Linux which makes it beneficial to have on almost any Linux system? According to Alan, things get very bad when a Linux system hits swap. How can behavior like this be beneficial: When a linux machine hits swap, it does so very aggressively, there is nothing nice about it at all. The entire machine slows to a painstaking crawl for easily a minute at a time while the kernel writes pages out to disk, and disk is thousands of times slower than RAM. This is not entirely true. There's regular swapping and there is thrashing. Thrashing is indicative of a memory-starved system, i.e. when many processes are trying to access memory, but there just isn't enough and the system is frantically swapping in/out. I'm talking about your normal day-to-day swapping that you probably don't even notice. It gets so bad that you can't even run a shell properly to try and see what's going on and kill the actual memory hog. Again, that is thrashing. I'm talking about normal swappage. Dont throw the baby out with the bath water. Also, aren't you likely to wear out your hard disk sooner using swap? Is this coming from someone who uses Gentoo linux, which is constantly downloading/compiling/linking object files? Syslog and other loggers writing everything under the sun to a log file. Backups, journal writes, database transactions, etc. Compare how many disk transactions take place during your normal Gentoo usage versus a few megabytes here/there being swapped in/out. Again, I'm talking about regular swapping, not oh my god I has no RAM and my hard drive won't stop Even so, we're talking about modern drives here. This isn't the 1960s.

I haven't dropped coin for an SSD (yet), but I was wondering about uses for them beyond using them for / or /home. 1) What about sitting swap (partition, file, whatever) on the SSD? Presumably, in scenarios where expanding the RAM in a system is prohibitively expensive, an SSD could reduce the impact of swap thrash. Sure why not. However, if you plan to swap constantly, I'd recommend doing a prediction of the life-time. For normal usage, the number of possible write cycles should be sufficient. 2) While my system rarely goes above using 2-2.5GB of RAM, I enjoy having 6-8GB of RAM, just for the file cache. Of course, I lose that when I reboot; the cache needs to be repopulated. Has there been any work in the kernel for doing things like Vista/Win7's ReadyBoost? ReadyBoost has a ridiculous limit to only using 4GB of a flash drive, but I'd think that an 80GB SSD would be a massive performance improvement. You should try sys-kernel/tuxonice-sources for suspend-to-disk. It preserves the cache as well. Obviously, for something like Gentoo, putting an SSD-based filesystem under /var/tmp makes a lot of sense, but what other uses have been tried? How'd they work out?

That prompts one to ask the question: Does spinning a drive up/down every day lengthen or shorten it's life compared to having it on 24/7 (assuming the same number of seeks in both cases). I think it is generally believed that by NOT spinning down the drive, you are going to shorten its life-span. Any HDD made in the past few years are designed with spin-up/spin-down when idle in mind. Constantly spinning will probably wear it out faster than regularly spinning up and down. It should be able to handle thousands of spin-up/spin-down cycles with ease. I think SMART will tell you how many times it has happened. In my case I disabled it because I found it to be annoying and inappropriate for my RAID, but I realize I'm wasting power and probably jeopardizing the long-term health of my drives by not allowing them to spin-down.
Re: [gentoo-user] How to cross compile Perl for ARM?
Hi Raffaele, Gentoo Cross Development Guide is deprecated in favour of Gentoo Embedded project, which so far seems to suit my needs. I had a quick look on CodeSourcery's products a few days ago, but in freely available version they don't seem to offer me more than toolchain compiled with crossdev. Maybe I'm wrong and if I'll get stuck I'll give them a go. AFAIK the biggest disadvantage of crossdev-created toolchain, compared to other cross compilation tools, is that without usage of emulator (like qemu-user) it is not possible to compile things that use in their configure scipts checks that need to be run on the target architecture (like Perl). Sticking to arm-none-linux-gnueabi-emerge offers quite a lot of comfort so far, so I'll see where I can get. Thanks for your tips!

Re: [gentoo-user] How to cross compile Perl for ARM?
Hi Raffaele, how far did you get with compiling rootfs? Do you have complete gentoo installation including kernel compiled for ARM? Would it be possible to make vmdk/any other image for Qemu in which it could be run? I guess it would ease quite many things... As for my progress: I found out that patches from Cross directory does not work, but configure script has some options for cross compilation so I wrote ebuild with different parameters for perl Configure script. It assumes that you have ARM machine ready on network and with ssh daemon running - it uses ssh to transfer cross compiled binaries, run them remotely and uses the output to continue compiling on host pc. I had no problem with establishing that, but configure script still tries to run few binaries compiled for ARM on my x64 host machine. Fight continues!

Okay, I may have misunderstood your needs the first time around (blame it to not having my first cuppa tea of the day). So, you want to do these steps: - Pull email from an IMAP account in box A - Filter it in box B - Push it to box C So, the third step is not an LDA. There are some alternatives, none of them are simple, though. The 'easiest' I think would be: - have fetchmail (on box B) pull email from box A, and deliver to local maildir (on B) via procmail+SA - have Dovecot watch the local maildir - have *another* fetchmail instance pull email from the local Dovecot and push it to an SMTP MTA on box C You can have multiple fetchmail daemons running at the same time by copying/symlinking the fetchmail initscript and creating a correspondent conf file. I've submitted a patch (that has been accepted into the tree) that allows multiple fetchmail daemons. Rgds,

(But you might get troubles if you do not use eclasses or other ebuilds from the overlay which might contain corresponding patches). Surely you can see the value in finding an ebuild for a package you like that isn't in portage, adding the overlay associated with that ebuild via layman, somehow specifying that you only want that package from the overlay, and running 'layman -S' to stay on top of version bumps. If I understand your suggestion correctly, it would involve manually checking for version bumps and recopying them into the local overlay. That doesn't seem very Gentoo. Agreed. I may not want to add the whole overlay. That's fine for things like the kde or vmware overlays that have a specific focus, but sometimes I find a package I want isn't in portage but is in an overlay, but adding that overlay pulls in all sorts of other packages, sometimes beta or unstable versions. However, the idea of setting overlay order sounds interesting as it would at least solve part of the problem. For now, symlinking rather than copying, which I tried before, at least keeps things up to date. -- Neil Bothwick Snacktrek, n.: The peculiar habit, when searching for a snack, of constantly returning to the refrigerator in hopes that something new will have materialized. signature.asc Description: PGP signature

Simple, I have never had to resize / or /boot before. I have had to resize /usr, /var and /home several times tho. THAT is the reason. Ok, but... everything I've read and personal experience over the years shows that space required for /usr should not change much, especially constantly grow over time (like requirements for /home can and will)- it may fluctuate (increase, decrease) *a little* over time, but it definitely should not grow substantially, so, if you had to resize it, most likely it is because you simply didn't allocate enough room to start with. For me, it doesn't matter if it is rational to YOU or not. Sorry, but rationality is not subjective. Just because something seems to be rational to you doesn't mean that it is. You have still not stated a logical, rational reason for wanting a separate /usr. I am the one doing things on my puter not you or anyone else. If the init thingy fails, that will be me staring at a error message, not you. I don't want one of those things either, but that isn't what I was questioning you about. Of course you can do whatever you want *and* are technically capable of on your own computer, but that doesn't automatically make those things logical or rational. I did see one good case for a separate /usr (someone who was using ancient PATA drives, and something about striping for performance), but that was obviously a corner case...

Acutally, from my research and my goal (one really big scientific simulation running constantly). Many folks are recommending to skip Hadoop/HDFS all together and go straight to mesos/spark. RDD (in-memory) cluster calculations are at the heart of my needs. The opposite end of the spectrum, loads of small files and small apps; I dunno about, but, I'm all ears. In the end, my (3) node scientific cluster will morph and support the typical myriad of networked applications, but I can take a few years to figure that out, or just copy what smart guys like you and joost do. We use Lustre for our high performance general storage. I don't have any numbers, but I'm pretty sure it is *really* fast (10Gbit/s over IB sounds familiar, but don't quote me on that).

Samsung wouldn't have chosen systemd for Tizen if it were too resource hungry for its use case. Embedded is a pretty broad term, and it impacts all aspects of a device's design. You can't really put a smartphone and a microwave in the same category. Phones actually have plenty of storage, RAM, and CPU by most embedded standards. The main issue is battery use, which is mostly about ensuring that your software isn't constantly waking up the CPU. If systemd is well-behaved in this regard I'd expect it to work on a phone just fine. The thing is that most devices that couldn't run systemd would probably be hard-pressed to run any kind of generic linux distro in any case. They might not even run linux, or if they did it might be a super-stripped-down build with an embedded initramfs containing nothing but a single executable built in C which runs as PID 1 (no need for even filesystem support, let alone stuff like /proc and so on). I'm genuinely curious as to how systemd and competing solutions are adopted in the embedded world, including phones but especially getting beyond this (huge) niche. I'm also curious as to where ChromeOS ends up going. It is based on Gentoo, but runs Upstart (which isn't used by just about anybody else now, and which isn't even in Gentoo's portage). -- Rich

They were left stagnant for a long time due to some really finicky software (tried an upgrade and it broke so many things on that software it wasn't funny.) However, this process took almost a week to iron the bugs out. Portage had a bit of a fit and refused to do anything. There were so many changes with core things (like udev, python, perl, and numerous others) that it just crapped out. I found that I had to do it in little pieces at a time and portage got in my way constantly. I wish there was a setting to just forcibly compile a package and then manually deal with breakage afterward with something like revdep-rebuild, rather than trying to solve problems it can't deal with beforehand. It would have been a lot easier. So after upgrading some core items which took several hours of figuring out what to remove, what to upgrade, and what to switch to (in some cases) then I could install a new kernel and boot, after that I still had portage getting in the way and wound up installing packages manually instead of emerging world. I would've just started fresh if the software package I was using actually had an installer that worked.

Well, I am trying to use the nvidia driver which conflicts with uvesafb frame buffer, so it seems. It used to work fine, but not it does not work anymore and the only solutions I have found was a couple of grub parameters which gives you a higher resolution and passes it on to linux.

OK, so both of you guys should use serial sniffers and usb sniffers and log
those sessions on a separate machine for rigorous analysis. Commercial
sniffers are very user friendly. Some cheap embedded boards can sniff usb
readily (but you'll have to search them out yourself).
For a usb sniffer, you may need special hardware to intercept those singnals
from the actual communications link. sniffing from inside
of a host is sometime problematic on catching every charcter, timings,
and other such critical signal information. sniffing RS-232 is well
documented around the net. When I sniff usb, I try to first use usb-1.0
or 1.1, as the slower speeds are easier to watch and collect critical data.

I constantly see the same conflict and haven't nailed it down exactly right now. It seems to happen when one package requires a binary compatibility to an older version of a depend but can also be built against the newer version. Usually, emerge should trigger a rebuild then. But this doesn't seem to work when both packages (the depend and the depender) are updated at the same time. Portage then pulls in the old and the new version of the same package at the same time, resulting in a conflict. Upgrading the depends with "-1a" first sometimes helps but usually I'll also resolv it by unmerging the conflicting package first. -- Regards, Kai Replies to list-only preferred.

Okay, it really depends. I shouldn't say "most"... ;-) I compared my really crappy (but most reliable yet) old USB stick to my internet connection. My USB stick doesn't do 48 MByte/s, more like 5-10. And don't even ask when writing data. Even my rusty hard disk (read: not SSD) has a hard time writing away a big download with constantly high download rate. But I guess that a good internet connection should be at least 50 MBit these days. And most USB sticks are really crappy at writing. That also counts when you do not transfer the file via network. Of course, most DSL connections have crappy upload speed, too. Only lately, Telekom offers 40 MBit upload connections in Germany. I'm currently on a 400/25 MBit link and can saturate the link only with proper servers like the Steam network which can deliver 48 MByte/s. -- Regards, Kai Replies to list-only preferred.

I don't think you get that level of fine-grained control. You can't just pick the codec and features. You pick the target platform (optimize for Android, or a generic Optimize for "Mobile", etc), and you pick the resolution/bitrate from a list of presets. I'm not sure how easy it is to tweak the actual settings, though maybe it is possible. On MythTV the transcoder isn't exactly super-flexible either. On either platform you could also do your own transcoding. With MythTV the regular player tends to be pretty picky about how files are encoded (at least it used to be).

I couldn't tell you how well they work with ATSC. The bigger pain is the way they're encoded into shows. If they're done right you can do things like have captions only for foreign language phrases (works great in Star Trek Discovery). If the subtitles aren't set up the way it expects then you find yourself constantly turning them on/off when the show contains extensive use of foreign/fictional languages. I suspect the issue is more in my source material there, though I can't vouch for how well it works over ATSC. With ATSC I'd think that foreign language subtitles would be more likely to be burned in anyway. -- Rich

Correction; the OS is not Windows or Android, but rather KaiOS. This is an Alcatel Go Flip.

Of course, the only thing being fed to gpg in the git case is the git commit record itself, which is about 10 lines of text. That record contains a content hash of the tree record, which in turn references content hashes of every directory inside, and so on. So, with git most of the hash validation is happening constantly just by virtue of everything being content-hashed, and the only extra layer with the gpg signature is to sign the top level of the whole tree. Now, on the flip side, some of those git operations might take time since it is stating files for things like git status/etc. I've never noticed an issue, but I'm also on an SSD and tend to always have a warm cache when I'm using it. emerge shouldn't need to trigger any git operations except when syncing. -- Rich -- Rich

Before I got my first smartphone, I had an iPod touch that I loved. It was great for e-mail, games, music, etc. But, it was a nightmare tryhing to get files to/from it. At the time, you couln't use Linux _at_all_ with the touch models. Some of the older iPods would work with certain Linux apps, sort of, somtimes, if you spent hours bashing your head against a wall, and the phase of the moon was right. iTunes on Windows was also a nightmare, but it usually worked, eventually, after a few crashes and restarts. Then I was given an iPad. It was also a lovely device, but it had the same hatred for Linux (and almost as much for Windows). When I finally broke down and got a smartphone I abandoned iOS and went Android -- and transferring files was trivial and reliable. I'm on my fourth Android phone, and it still is. I also gave up on the iPad and am on my second Kindle Fire. IMO, you should only buy an iOS device if you're never, ever, going to want it to interact with anything non-Apple. -- Grant

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).

This varies and the ones that cost more will get more writes (often significantly more), and wear pattern matters a great deal. Chia fortunately seems to have died off pretty quickly but there is still a ton of data from those who were speculating on it, and they were buying high end SSDs and treating them as expendable resources - and plotting Chia is actually a fairly ideal use case as you write a few hundred GB and then you trim it all when you're done, so the entirety of the drive is getting turned over regularly. People plotting Chia were literally going through cases of high-end SSDs due to write wear, running them until failure in a matter of weeks. Obviously if you just write something and read it back constantly then wear isn't an issue. Just googled the Samsung Evo 870 and they're rated to 600x their capacity in writes, for example. If you write 600TB to the 1TB version of the drive, then it is likely to fail on you not too long after. Sure, it is a lot better than it used to be, and for typical use cases I agree that they last longer than spinning disks. However, a ZIL is not a "typical use case" as such things are measured. -- Rich

Now for your own sanity you might consider stopping adding things globally constantly, and using app-portage/flaggie to sanely manage them per-package...

ROFL Note that people used to shoot themselves in the foot when lazily (or by accident) adding a single disk to an existing pool. If that pool was composed of RAID vdevs, then now they had a non-redundant single disk in that pool and it was not possible to remove a vdev from a pool! That single-disk vdev could only be converted to a mirror to at least get redundancy back. The only proper solution was to destroy the pool and start from scratch. By now there is a partial remedy, in that it is possible to remove mirror vdevs from a pool.

While ulimit/cgroups/etc will definitely do the job, they're probably not the solution you want. Those will cause memory allocation to fail, and I'm guessing at that point your torrent software will just die. I'd see if you can do something within the settings of the program to limit its memory use, and then use a resource limit at the OS level as a failsafe, so that a memory leak doesn't eat up all your memory. Otherwise your next email will be asking how to automatically restart a dead service. Systemd has support for that built-in, and there are also options for non-systemd, but you're going to be constantly having restarts and it might not even run for much time at all depending on how bad the problem is. It is always best to tame memory use within an application. Something I wish linux supported was discardable memory, for caches/etc. A program should be able to allocate memory while passing a hint to the kernel saying that the memory is discardable. If the kernel is under memory pressure it can then just deallocate the memory and then have some way to notify the process that the memory no longer is allocated. That might optionally support giving warning first, or it might be some kind of new trappable exception for segfaults to discarded memory. (Since access to memory doesn't involve system calls it might be hard to have more graceful error handling. I guess an option would be to first tell the kernel to lock the memory before accessing it, then release the lock, so that the memory isn't discarded after checking that it is safe.) -- Rich
[gentoo-user] Don't be like stupid me!
Hello, gentoo. I was wanting to do a pretty full build of my Emacs working repository. This involved first purging al *.elc files. The way to do this is $ find . -name '*.elc' | xargs rm .. But for some reason, I typed $ find . '*.elc' | xargs rm .. I even carefully checked it before pressing RET. However, press it I did, instantly deleting all files in my working directory. OUTCH! So, I fell back on my backup from last Sunday. After about 1½ hours trial and error, I had my source files as of last Sunday back again, though git could have been more helpful than it actually is. Thankfully, I had Emacs open, with all the files modified since Sunday in buffers. So, I laboriously worked through Emacs's buffer list, saving those ones I'd since changed. I lost all my timestamps on the files, and lost all my Emacs backup files (things ending in ~ which Emacs constantly makes). But my software builds and runs. It could have been a lot worse. Boys and girls, don't use $ find | xargs rm unless you really know what you're doing. And even then, it's probably better not to. ;-( It occurred to me fairly quickly after that press of RET that I could have done well with a COW snapshot facility, something which has been discussed at length on another recent thread. I even have LVM on my machine for its RAID capabilities. But I've never bothered before. I mean "I'm too careful", amn't I? ;-( At least I do a weekly backup, though. So, in the end I managed to recover fairly well, thankfully. -- Alan Mackenzie (Nuremberg, Germany).

Model and profile the activity, set soft (say 5%) and hard alarms (10%) for certain types of traffic flows that could contain interloper activity. Then add tools that analyze the traffic, where you perceive vulnerability. If your organization does not have a pathelogical hacker on the payroll, then consider retaining a consultant periodically to perform penetration tests. Stay away from corporations, as most of their talent pool, is on the weak side of modern genectic apptitude. Lock up your special consultant with a aggressive legal contract. Some really paranoid groups get different special consultants to perform penetration tests over time. Layer your security through several firewalls. Partition the network via managed switches. If you suspect an internal interloper, then put him on an isolated segment with a stealth sniffer monitoring his activities.

If the rub is really the gcc compiler, then do not have it installed; activate a remote partition with any such tools as gcc, coreutils and use them for admin things.

Prolly (I like this term so much, I borrowed it from another gentooer...) what you will discover is other admins do not like your Gentoo tendencies, because it's not their idea (just a hunch) My experience is when you constantly flesh_out a system and constantly update stuff, it stays more secure. Systems that get little attention are where the interlopers like to hide; imho. Gentoo does fall short on anomaly detection as do most operating systems, but, it's easy to remedy with modeling, profiling and analysis of the traffic flows I find the best security is obscurity, and secrecy of the admin's tools and traits for administration. Don't follow the herd/vendor rhetoric. Using the common approaches to security, makes your life much easier. Add your own unique spices to the mixture of security tools you use. The change_up is the best and easiest pitch in baseball. Some admins never use the change_up? SElinux is superb but a pain in the waz. Lots of folks do not trust the NSA, mostly from a historical perspective. All governments have a vested interest in their citizens and businesses having really secure computers and networks. It makes their jobs (the spoofs) much easier. SElinux is focused on software security policy enforcement (orange book). SElinux in and of itself, is not a complete solution for a tight network. It is a component that needs to be augmented with network and statistical tools and lots of tricks. Without admin tools, it is tedious and laborious, imho.

It isn't really a focus of development as far as I'm aware. I probably wouldn't use it.

So, F2FS is of course very promising on flash. It should be the most efficient solution in terms of even wear of your drive. I'd think that lots of short-term files like compiling would actually be a good use case for it, Since discarded files don't need to be rewritten when it rolls over. But, I won't argue with the benchmarks. It probably will improve as well as it matures. However, it isn't nearly as mature as ext4 or xfs, so from a data-integrity standpoint you're definitely at higher risk. If you're regularly backing up and don't care about a very low risk of problems, It is probably a good choice. > d) I'm not sure about BTRFS, since it is very sophisticated and I'm > not interested in its advanced features such as snapshots, > checksums, subvolumes and so on. In some tests [2] it tends to > achive better performance than ext4, but due to its sophisticated > nature it is bound to add more code paths and latency than other > solutions. The only reason to use btrfs at this point are all those advanced features, such as being able to copy a directory with 10 million small files in it in 5 seconds. I'd think that might be useful for development, but of course git does the same thing. Git and btrfs are actually somewhat similar in principle. Take git with the ability to erase blobs and mirror things and that is kind of like btrfs. Btrfs is also immature, and while data loss on an n-1 longterm like 3.18 is fairly rare it does happen. It is optimized for ssd but generally tends to underperform the write-in-place filesystems, mainly because it isn't optimized, and of course it can't write-in-place. If you REALLY don't care about the data integrity features and such then I don't think it is the best solution for you. > P.S. Is aligning to erase block size really important for NVMe? I > can't find erase block size for this drive (Samsung MZ-VKV512) > neither in official docs nor on the net... Unless the erase blocks are a single sector in size then I'd think that alignment would matter. Now, for F2FS alignment probably matters far less than other filesystems since the only blocks on the entire drive that may potentially be partially erased are the ones that border two log regions. F2FS just writes each block in a region once, and then trims and entire contiguous region when it fills the previous region up. Large contiguous trims with individual blocks being written once are basically a best-case for flash, which is of course why it works that way. You should still ensure it is aligned, but not much will happen if it isn't I'd think. For something like ext4 where blocks are constantly overwritten I'd think that poor alignment is going to really hurt your performance. Btrfs might be somewhere in-between - it doesn't overwrite data in place, but it does write all over the disk so it would be constantly be hitting erase block borders if not aligned. That is just a hand-waving argument - I have no idea how they work in practice. -- Rich

For example, as I write this I'm seeing this in my logs: snip I'm using denyhosts but it seems that it doesn't deny anyone until an hour has passed, despite the fact I'm using the daemon which constantly monitors the log file... by which time hundreds or thousands of attempts can be made. Maybe that's a configuration issue on my denyhosts setup, but shouldn't sshd be blocking them in the first place? Thanks, Paul I'm pretty sure MaxAuthTries 3 does nothing more than disconnect you after 3 failed connections (meaning all you have to do is reconnect to keep trying)... it doesn't do any sort of 'intelligent' protection of the system. DenyHosts worked great for me while I used it, but I also found that a firewall rule limiting connection attempts to 3 per source IP per 10 minute period put a big dent in the number of tries that denyhosts ever even had to see (though they were always enough to get that source blacklisted, I had things set rather restrictive). Something I was pointed towards on IRC, in the event that the SSH server you're running is primarily for your use or the use of knowledgeable users (fellow admins)... look up Single Packet Authorization (SPA). I'm using the online denyhosts synchronization database, I think that may negatively affect how often it blocks hosts locally, because it waits until it does a remote sync to scan the local file. This is my theory. I like the idea of sharing my blocks and taking advantage of the blocks of others, but if it renders the program ineffective against the IP /actively/ attacking my system, then it's pointless. I'm going to turn off the online sharing of denyhosts and see if it makes a difference. Otherwise I guess I need to set up some kind of local firewall on this machine to get any more fine control over the connections. Thanks Paul

[gentoo-user] Hardware issues, probably overheating, help?
Hi, I've been having issues with the computer shutting down automatically. Makes me wonder if it's an over heating problem. The system (AMD Sempron 2500+, MSI K8M800 mobo, two Seagate HDDs, an LG DVD Burner and a GB of RAM) has developed a habit of shutting down or restarting randomly, no matter what OS I'm using. A few days ago, the system shut itself down. I pressed the start switch but it would not respond, instead the power LED just kept blinking. I thought it to be an overheating issue and let it cool off for a bit. It worked fine for a few days and then this phenomenon just kept repeating itself and the frequency increased. There were a few lockups in between too. This would happen when running and update world while running Azureus in KDE or even when I was doing something as trivial as just chatting. One day, the system refused to start. I pressed the start switch after a few minutes of such a shutdown and all that happened was I could see the power, HDD LEDs and the DVD burner's LED all glowing, but the monitor wouldn't start. The CPU fan would be working. I let the thing sleep for a few hours. Later, I though I'd just run memtest to check if the RAM modules aren't causing any trouble. The pc actually started this time, but as soon as the memtest86+ screen came up, the thing shut itself down once again. Next day, I had the system lock up twice while editing the BIOS settings. This time I decided to dig out the processor and take the board and the processor to the dealer for checkup. Turns out that the processor had got stuck to the heat sink. After separating and reinstalling the two, the system worked fine for a few days. Now, again, a couple of days ago, I had the shut down. This time I decided to keep the room as cool as possible and have been running the computer with the lid open. But then again, just a few minutes ago, I had the shutdown while compiling K3B while running KDE and Azureus. Since then I've put up ksensors to check the temperature constantly. It's showing a pretty neat 35C right now, running Azureus, Kmail and Kopete. Anyway, the point of this lng emails is that I haven't exactly pin pointed the problem.

[gentoo-user] Problems with the GLI on the x86 2006.0 LiveCD
Hi List- Some hardware issue requires me to boot the subject CD with either the nodetect or nohotplug parameters. Without one of these, the boot process hangs when detecting pnp hardware. I suspect that the cause may be one of the two Digium PCI cards that I have in the machine, but not sure. So I'm booting the LiveCD at the grub prompt with this command: gentoo-nofb nohotplug Happily, in spite of this, my NIC is being detected and the correct (tulip) module is being loaded for it automatically. However, the curses-based GLI is failing on me constantly at the stage where I manually configure the NIC. I've tried this many times, and every time, the installer program fails with the words: The setup program seems to have failed That's all I get. I've also tried setting up the network manually by editing /etc/conf.d/net and starting up the network, then starting sshd, then remotely logging into the box and running the installer that way. That method gets me past the network config part of the GLI, but I've found that the installer crashes at various other points also: when I try to save the XML profile and a few other points that I've just learned to try and avoid as I walk through the installer steps. But I'm at the point now where I've run the installer 15 or 20 times and every time it ends the same way, with the error message above. Sometimes it ends this way at the network config step, other times it ends this way at other steps, but it always crashes. Plus, I can't find anywhere in the script that it allows me to set mountpoints for the partitions that I've created. Is anyone else seeing this and can anyone recommend a work-around? I'd be happy to share my dmesg output or any other details if someone thinks it would help improve the installer program. Since the 2006.0 handbook assumes that I'm installing with the GLI, it seems that my only other option for installing is with the minimal CD and the general installation handbook. If anyone has other ideas on how to install from one of the 2006 series of CDs, I'd very much appreciate learning of them. TIA for any suggestions. -Kevin -- gentoo-user@gentoo.org mailing list

And if you aren't writing toolkits or apps using xlib directly, you don't need to care about most of the stuff. So hobbyist concentrate on the easy stuff - and a userland is not easy. Userland is not boring - it is very hard. And the best userland doesn't help you if no 3rd party software runs on it. But projects like Haiku and ReactOS created also most of userland from scratch, not only the kernels. They had the advantage of taking inspiration from existing OSes but they actually did the implementation. Also, SkyOS or Syllable did it, AFAIK. So I can rephrase my question as those two: Why didn't those projects use the Linux kernel? Are there similar projects using the Linux kernel? m.

Can someone offer me some assistance as to why this might be? Thank you (This is my first mailing list post - please be gentle!) because a large part of the dvb/tv drivers are developed outside of the main kernel tree. Also a large part is hidden under experimental. For my dvb-t stick I need to checkout a mercurial rep and do a make, make install in it do get drivers that work. And with 'work' I mean: no sound on first try, but after disconnecting the stick and reconnecting it, it suddenly works. Hi, I went thru this process but i still dont have the option to add support as a kernel module. Should the mercurial add steps to the menuconfig? no. it just installs all the drivers in the rep as modules. It doesn't touch any configs at all. Hmmm i wonder why i have seen sooo many references to alot more kernel options than i have in either my gentoo-sources or vanilla-sources. because they patch their kernel. Is it possible to 'patch' the kernel source instead of downloading using mercurial. Also how does it 'know' what kernel to make the modules available under? I have 3 sets of kernel code on my machine? a) /usr/src/linux b) uname -r c) just make clean make make install for every kernel. Why patch at all? with the rep and make make install you get all the drivers. It is not that much 'overhead' compared to the work of patching the kernel. And you don't even need to worry about which driver you need - autoloading will do that for you ;)

[gentoo-user] SMTPS not working after upgrade 4.43 to 4.50

I upgraded from 4.43-r2 to 4.50-r1 as per portage's suggestion and now I can't SEND mail from Outlook through my server to anywhere using SMTPS. This worked fine earlier today before the upgrade. I don't see any readme or other txt that would indicate I needed to configure something. there was no etc-update files to examine either. checking here, i don't see any known bugs re: my issue. http://gentoo-portage.com/mail-mta/exim/bugs this also talks about port 465, but i'm using port 25 according to outlook. this chapter talks about SSL, but it's over my head. http://www.exim.org/exim-html-4.50/doc/html/spec_38.html like i say, this worked earlier with the lower version, so i assume my config files are correct. If i disable SSL in outlook for outgoing, then i can send mail to my exim server (daevid.com), but can't send to anywhere else as relay not permitted [which is expected] If i check the SSL box for outgoing SMTP (like i has always been), then mail never leaves outlook. it just constantly tries to send. i can send mail using 'pine' from the server to anywhere. i don't see any messages in the log file ?! i do have a firewall (shorewall). did some port change now that i need to open? here are the parameters for exim that i have in my emerge: [ebuild R ] mail-mta/exim-4.50-r1 +X -dnsdb -exiscan -exiscan-acl +ipv6 -ldap -lmtp -mailwrapper -mbox +mysql -nis +pam +perl -postgres -sasl +ssl -syslog +tcpd 0 kB so +ssl is on. i recieve mail just fine. so at the moment, no users can send mail basically and i'm dead in the water as we require SSL to send so that we're not an open relay. :( I tried to post to the exim list but they have dynamic IPs blocked via an RBL list even though you have to be a member of the list to post -- very helpful.

If I were attempting to make your processor work differently, I would concede the point. But there's many more requirements for a kernel than just supporting the processor and other hardware. It also has to support software, namely in this case udev. Not having proper udev support could certainly cause the problems we're seeing here, don't you think? I don't need all the bells and whistles. Don't need X or gnome or even a mouse. I'm kind of a minimalist too. _My_ laptop is a Pentium 166. Nevertheless, I try to keep it up to date. 2.6.12 was a long time ago -- http://kerneltrap.org/node/5308 dates it at about 20+ months old, being from late june 2005. Also, upgrades are difficult here in the boonies. Modem speed is approx 28k. I feel your pain. I was on dialup for a long time. I was actually running a 2.4 kernel 8 months or so ago, and that was really outdated. Getting it up to date was a real pain, and I wish I would have saved myself the hassle and updated it regularly. That was a learning experience; ) I got newer software on the working PC, 2.6.16, So it's not exactly bleeding edge but it works fine. I could transfer the newer stuff with ssh but that doesn't seem to be working either. Probably a similar problem. Udev would be responsible for creating network devices such as eth0 based on -mw I agree that you never really need the latest and greatest. That's especially true for hardware when you run gentoo. But software changes quickly, unlike hardware, and is constantly improving. You don't necessarily get bells and whistles, you get bug fixes and performance enhancements as well. Bells and whistles can be left out of the kernel easily enough. I guess you could count udev as a bell or whistle, in which case you could always manage a static /dev by hand. I don't know how to do this, or I probably would on my laptop. Good luck with your /dev problems, and may the solutions be swift and painless ; ) -- Dan -- gentoo-user@gentoo.org mailing list

Be sure to use a network that isn't on your local net for testing, as my network is 192.*, I've used 10.* in the example. If you use a network that's regularily used on your network, you might get problems discerning the sleep phase, as the arp address of your laptop propagates to all other endpoints on your net due to the use of a regular network, and this might mean a lot of ARP queries, depending on your network size.
