Regardless of the fact that my router/modem does or does not support ipv6, if I don't have ipv6 service from my ISP (or a tunnel broker) ipv6 is pointless. But harmless.

Re: [gentoo-user] tmux vs. screen
These days tmux seems somewhat more actively developed, this might be a subjective appreciation, though. But at least the tmux mailing list seems more active. I am subscribed to both of them. The feature that made me switch from screen to tmux back in the days was vertical splitting, which just worked and worked well (not at turtle pace, not blowing my cpu like in screen). It happens that nowadays I no longer use that feature, but I kept tmux because I find it simpler to handle, because it's lighter in my RAM, and because a few problems with screen (besides splitting) that I no longer remember. I switched long ago. I have no idea if my concerns about screen still hold true. Not do I care, since for now I have no need to change back. -- Jesús Guerrero Botella

I ran speed tests to my ISP and I get 5M(should be 15M) down and 2M (yipee!) up to a local test server the ISP operates, so that's not the bottleneck. From what I could tell, the net had(ha) problems last night. Many of the mirror I tested last night manually, did not respond for quite a while and the latencies where all over the place (60 -6000) and packet losses where 30-70%. I could have been BrightHouse and their (MPLS) issues, or elsewhere. Any good recommendations on on the Internet Traffic status? The net looks horrible here: http://www.internettrafficreport.com/main.htm I sure wish mirrorselect, was somehow more dynamic, meaning the download could switch mid-process, to another source, if there was a 50% or so faster download link available. You know some sort of state table maintained on link speeds to my top 12 mirrors close to my net (fastest throughputs). (urely I dream.) as this download will take 6+ hours (at 120KB/s)... thanks to all for the suggestions, James

[gentoo-user] Nepomuk indexing, what triggers it?
Hi all, Haven't had much luck finding this info: If I reboot this machine and start KDE, Nepomuk starts a rather long-lived index of my home directory. It takes up about 30-40% cpu and lasts as much as 15 minutes sometimes. This is annoying because after a reboot I usually want to catch up on mail, rss feeds and fire up VirtualBox. So nepomuk is just wasting my time at this point. How does nepomuk know when to do it's thing, how can I tweak what it does and how can I discover why it feels it necessary to reindex my entire maildir when surely it has a perfectly valid index already from just before I shut down?

[gentoo-user] [OT] Finding old files
Hello list,
Just to expose my ignorance again, would someone lift my blinkers
please? I'm recovering from an infection and my brain is stuck.
It's time to start pruning old stuff from the website I run, which has
2200 files in 200 directories.
I'm trying to find old images like this:
find . -iname \*.jpg -exec ls '-cdl' {} \; | cut -d \ -f 5-10
But this excludes the year (even though listing an old file manually
shows the year if it's over 12 months old), so I can't use that to
decide. If I do this:
find . -iname \*.jpg -exec ls '-cdl --time-style=full-iso' {} \; |\
cut -d \ -f 5-10
I get an error message: ls: invalid option -- ' '
Why does ls differ when executed by find from on the command line?
Is there a simple way to do this? Ideally I'd like a chronologically
ordered list of the files. I have noatime set in fstab, so I'll have to
rely on creation or modification date.

So nepomuk is just wasting my time at this point. My /guess/ is that it scans every time you restart to be sure nothing changed while it was shutdown. It doesn't know if you've dual-booted, logged into xfce, mounted the disk in another machine, had fsck remove files, etc. I think Tracker behaves the same way in gnome-land. How does nepomuk know when to do it's thing, how can I tweak what it does and how can I discover why it feels it necessary to reindex my entire maildir when surely it has a perfectly valid index already from just before I shut down? I am pretty sure it is tied to your KDE user session, and not running as a system daemon in the background. Perhaps you can suspend it via some autostarting script, and then resume it after whatever amount of time you're comfortable with. Looking in here: http://api.kde.org/4.5-api/kdebase-runtime-apidocs/nepomuk/html/classNepomuk_1_1IndexScheduler.html In the indexing speed settings, it says: enum Nepomuk::IndexScheduler::IndexingSpeed Enumerator: FullSpeed Index at full speed, i.e. do not use any artificial delays. This is the mode used if the user is away. ReducedSpeedReduce the indexing speed mildly. This is the normal mode used while the user works. The indexer uses small delay between indexing two files in order to keep the load on CPU and IO down. SnailPace Like ReducedSpeed delays are used but they are much longer to get even less CPU and IO load. This mode is used for the first 2 minutes after startup to give the KDE session manager time to start up the KDE session rapidly. So based on that, for the first 2 minutes after KDE starts it should be using the least aggressive indexing speed (but indexing nevertheless). (Personally I've always had all that indexing/social-semantic-desktop stuff disabled completely.)

There's no such thing as file creation time on Unix - that has never been

ctime is the time the *inode* was last changed
mtime is the time the *file contents* was changed

ls as you are using it is an option to find (not an app or a shell

No, in his case ls it's an app that's executed by the find command by

It's obvious how that command finds old images. Can you explain what
it's supposed to do?
The cut command simply strips off the permissions, owner, group and file
size.
Never mind, anyway. I've done it by using separate steps instead of
trying to combine them. I'm still puzzled though at the different
behaviour of ls between command-line and execution by find.
ls as you are using it is an option to find (not an app or a shell builtin).
So you need to do
find -ls

find . -iname \*.jpg -exec ls '-cdl --time-style=full-iso' {} \; |\

What different behavior?
That ls command doesn't work from the command line either:
$ ls '-cdl --time-style=full-iso' foo
ls: invalid option -- ' '
Try ls --help' for more information.
The quotes cause both option specifiers '-cdl' and
'--time-style=full-iso' to be passed to 'ls' as single string with
whitespace in the middle of it. That's not how options are passed to
Unix command line utilities.
I think what you intended was
$ ls -cdl --time-style=full-iso foo
-rw-r--r-- 1 grante users 96 2010-11-19 11:44:45.0 -0600 foo

I think that's a bit silly, so do a full scan just in case stuff changed. If so, a very simple optimization would be to calculate a hash of some aspect of a directory, store the hash persistently, and only do a full scan if the hash is different. I haven't read the code, so I'm in no real position to know how it's done or how to optimize it. How does nepomuk know when to do it's thing, how can I tweak what it does and how can I discover why it feels it necessary to reindex my entire maildir when surely it has a perfectly valid index already from just before I shut down? I am pretty sure it is tied to your KDE user session, and not running as a system daemon in the background. Perhaps you can suspend it via some autostarting script, and then resume it after whatever amount of time you're comfortable with. Looking in here: http://api.kde.org/4.5-api/kdebase-runtime-apidocs/nepomuk/html/classNepomu k_1_1IndexScheduler.html In the indexing speed settings, it says: enum Nepomuk::IndexScheduler::IndexingSpeed Enumerator: FullSpeed Index at full speed, i.e. do not use any artificial delays. This is the mode used if the user is away. ReducedSpeed Reduce the indexing speed mildly. This is the normal mode used while the user works. The indexer uses small delay between indexing two files in order to keep the load on CPU and IO down. SnailPace Like ReducedSpeed delays are used but they are much longer to get even less CPU and IO load. This mode is used for the first 2 minutes after startup to give the KDE session manager time to start up the KDE session rapidly. So based on that, for the first 2 minutes after KDE starts it should be using the least aggressive indexing speed (but indexing nevertheless). Good find. Personally, I'd like it to wait for 10-20 minutes after session start, then just run at SnailPace period. This machine is seldom booted or even logged out of KDE (I suspend) so I can tolerate the wait as it's rare (Personally I've always had all that indexing/social-semantic-desktop stuff disabled completely.) Maybe I should too. But I *did* want to use this nepomuk thing myself for a while and see what the semantic-desktop can do for myself. It looks like it could be awesomely useful (like Google turned out to be awesomely useful) but it takes usage for real to know -- alan dot mckinnon at gmail dot com

[gentoo-user] Advice for System monitor + Intrusion Detection tools?
Hi,
I just want to beware of anything unusual instantly, preferably by
email. This is a single or two user laptop. Here are the few I gave a
shot:
Logsentry is very simple and easy to use with its plain rule files and
check script. It just works out of the box with almost zero
configuration. I only had to add couple of rules and modify
logcheck.sh according to my syslog setup. But it seems to be
unmaintained and more importantly it is not real time. There is an
hourly cron job shipped with the package but running it more frequent
sounds like overdoing it.
I also checked logsurfer which comes with a init script, however, no
working configuration file and sort of confusing examples.
Aide, as an intrusion detection tool, has also very simple
configuration but it does not report in real time either. You have to
place the example cron job to cron directory of your choice manually.
Running it hourly loads the system every hour for couple of minutes.
Running it daily mean knowing about the intrusion only the day after.
I don't see the point of that, it may be too late for everything.
I read somewhere that snort was the most used one. At first glance
there are too many configuration variables. It just seems overmuch for
what I want on my system.
What I want is something like tail using inotify:
tail -f / | mail $ME :)
Seriously, are there [or is there a single] tool/s for {system,
network, log} monitoring and intrusion detection, using inotify to
watch and email the instant changes on a system? What do you use and
recommend for a home pc?
eix -cSz ntrusion and log monitor show what is available in portage
but asking to share experience is a lot better than emerge-try-unmerge
cycle. Hope you agree.

We use OSSEC (http://www.ossec.net/) at work and it seems to perform well.
Alerts are almost real-time on Linux (using inotify) and it's able to classify
log entries into some hierarchy of importance. IOW you can cherry pick the
kind of thing you want to be told about.
And if you feel like being adventurous you can write plug-ins to deal with
logs that do not already have a scanner.
I can't comment on how much work it is, as a colleague set it up and I wasn't
paying attention. I can tell you that it does come with a sane config out the
box which might not be ideal for you, but is *much* better than having nothing
at all.
It does elementary IDS as well, but that is a different beast to log analysis
(like an MTA is different to anti-spam), best handled by a different product -
something in the same class as snort for example

Furthermore, sda7 was slower than sda5. I haven't measured latencies for first mount and subsequent look ups. I thought that it would be the same every time a partition fs is being accessed, no? Not at all. There's this thing the kernel does called caching. Yes, I know you can invalidate the entire cache and force the next read to come from disk, but that is completely devoid of reality. Very very few machines actually do that or anything remotely similar. So measuring it does give pretty numbers, pretty meaningless numbers. The kernel will cache the entire partition layout scheme and any mapping it needs in order to determine where blocks lie on the disk. Any thought that it won't is just so bat-shit insane and so far out there it's not even worth contemplating. Thus, the question that sparked this thread off is entirely moot. -- alan dot mckinnon at gmail dot com

Re: [gentoo-user] Nepomuk indexing, what triggers it?
Alan McKinnon writes: If I reboot this machine and start KDE, Nepomuk starts a rather long-lived index of my home directory. It takes up about 30-40% cpu and lasts as much as 15 minutes sometimes. This is annoying because after a reboot I usually want to catch up on mail, rss feeds and fire up VirtualBox. So nepomuk is just wasting my time at this point. How does nepomuk know when to do it's thing, how can I tweak what it does and how can I discover why it feels it necessary to reindex my entire maildir when surely it has a perfectly valid index already from just before I shut down? I think it starts scanning everything over again at every login. I've been also annoyed by that, so I deactivated it, and activate it from time to time when I am away, so it won't bother me. Or you can have it active, and during login you can suspend Strigi's indexing by right-clicking on the Nepomuk/Strigi icon in the panel. You might be interested in this article that came up on the Planet KDE RSS feed yesterday: http://www.afiestas.org/nepomuk-is-not-fast-is-instant/ It suggests to set fs.inotify.max_user_watches to something quite large like 524288 via sysctl. I assume this is the number of directories being monitored with inotify, and if this is larger than the total number of directories, changes in a directory will be noticed at once. So maybe this will avoid the periodic scanning at all? I did not try this yet. But it won't stop the first scan after login. I think I will have to trim the list of directories to index. Currently, I selected my and another user's $HOME, and some data directories. This gives 666,000 files, which is probably a lot. So I guess I'll skip my MP3s, as they are indexed already by Amarok, and also those many directories with source code. Wonko

Furthermore, sda7 was slower than sda5. I haven't measured latencies for first mount and subsequent look ups. I thought that it would be the same every time a partition fs is being accessed, no? I shouldn't design it that way. Would you? Consider the layout of the disk. First we have the master boot record, which contains the disk addresses of the four allowable primary partitions*, and not much else besides the primitive boot code to fetch the data from those addresses. Then each primary partition has the address of its first directory containing data. Those five parameters are assumed to be fixed and can be held in a small lookup table in the OS. One primary partition may be declared as an extended partition, by the setting of a single bit in its entry in the MBR**. That partition has to have the same header layout as the others, in particular not allowing more than one data address***. In this case it's the address not of the first directory but of the first logical partition - and that partition has to have the same header layout again, because it's just a partition full of data, isn't it? The answer to your question is that only very few values are needed to specify the fixed start points of all the partitions on the disk, and virtually no overhead is involved in storing them for the inevitably frequent use they're going to get. (Sorry if I'm rambling. I've been down with the dreaded lurgy for a day or two, and after a small glass of wine this evening I'm having trouble focusing on the screen, never mind my thoughts.) * One partition is plenty for all normal folk, especially those who run an OS that's convinced it's the only entity in the universe - who could possibly want more than four? And just don't mention 640KB memory unless you're prepared for fisticuffs. ** Talk about a single point of failure! *** Well, of course it doesn't, but what would we do without hindsight? -- Rgds Peter.

Re: [gentoo-user] One machine sends emerge text output to stderr, not stdout
On Fri, Nov 19, 2010 at 09:25:18AM +, Neil Bothwick wrote But harmless. The severe delays you noticed were the result of a broken modem/router failing to recognise that IPv6 was not available and trying to use it anyway. The usual fix for such a problem is a firmware update. It's more complex than that. How is the IPV6-enabled browser or media player supposed to know that my modem doesn't support IPV6 and neither does my ISP and neither do umpteen hops between me and the site I'm trying to connect to? See http://www.ipjforum.org/?p=378 The technology in web browsers and operating systems involves doing Domain Name System (DNS) queries for and A resource records and then attempting to connect to the resulting IPv6 and IPv4 addresses sequentially. If the IPv6 path is broken (or slow), this connection can take a long time before it falls back to trying IPv4. This process is especially painful on typical websites that retrieve objects from different hosts-each failure incurs a delay. The combination of operating system and web browser results in delays from 20 seconds to several minutes if the IPv6 path is broken[2]. The typical message flow of a TCP client is shown in Figure 1. Clearly, this delay is unacceptable to users. Users avoid this delay by disabling IPv6[3] or avoiding IPv6-enabled websites. The decision to enable IPV6 by default was a mistake. The only beneficial side effect was that it taught me not to do robo-updates any more G. -- Walter Dnes waltd...@waltdnes.org
