Re: [gentoo-user] Problem with script calling OOCalc on amd64
What does xterm -fg green -bg black -e 'gpg Personal/data.ods.gpg;echo $?' tell you? I'm thinking that gpg fails, so oocalc never launches (because you conditioned its execution with '', and the script continues to shred the file. My amd64 succeeds executing this (s/gpg/echo-to-tmpfile/). I would initially assume it's the usage causing the issue, rather than some arch-dependent thing.

Actually this is a Seamonkey error. Seamonkey 1 doesn't work with some
sites, banking mostly, and Seamonkey 2 just loves to send blanks emails
to mailing lists. I might also add that it is starting to get on my
freaking nerves pretty bad. That was a pretty long message with a lot
of info in it. Thanks for letting me know that Seamonkey was falling
down on the job again. I'm going to get a larger hammer here shortly.
;-) Here goes again.
I rebooted today after almost three months of uptime. I noticed these

There are more but they are all pretty close to this. I googled and
searched the forums and the best fix seemed to be to delete the files in

the same error message tho. Some more info:

P. S. Deleting those udev files tinkered with the names of my network
cards. So, if anyone reading this deletes those files, you may have to
dig around to find out which card is which again. Good thing is, they
are back in order again instead of jumping up, down then back up again.

Of course you did, udev is complaining about rules in /lib/udev/rules.d.
You have three choices
1) Ignore the messages, they are only deprecation warnings.
2) Fix the rules file(s) but they will be overwritten the next time you
update that package.
3) Bug the devs to fix it.
The only time to really worry is if you get these messages from your own
rules files, then 1 is not an option while 2 and 3 become the same.

On 15/03/2010 22:29, Andrea Conti wrote: This IMHO pretty much rules out any kind of server-class hardware, which tends to be both costly and power-hungry. If you're thinking about buying used stuff, be sure to factor in the cost and difficulty of finding spares in some years' time. I'm considering neither used equipment nor 'server-class' - the workload simply doesn't demand it. Given the point above I would also stick with software RAID. ... If reliability is your primary concern, I would go for a simple RAID1 setup; Absolutely. Software raid is cheaper and implies less hardware to fail. Similarly, RAID1 minimises the total number of disks required to survive a failure. It's the only way for me to go. If you do not need data sharing (i.e. if your volumes are only mounted by one client at a time), the simplest solution is to completely avoid having a FS on the storage server side -- just export the raw block device via iSCSI, and do everything on the client. This idea is on my wavelength. Has anyone on this tried this? My concerns are: 1. Are there reliability issues surrounding this technology in Gentoo? 2. Are there any howtos about putting as much of the file-system as possible onto an iSCSI device. 3. What's the best (most lightweight) way to expose the disk as a block device. I don't want to manage three fully-fledged Linux boxes. Can (cheap) NAS devices be used to export iSCSI to Gentoo? 4. What would be the strategy to 'secure' this iSCSI device... it would be a disaster if my WiFi were cracked and my data corrupted from a non-authorised host. In my experience this also works very well with Windows clients using the free MS iSCSI initiator. That's fantastic - I had no idea that such software existed. Now, I wonder, what's the most lightweight solution to get a couple of iSCSI devices? Does it help that MS supports attaching devices this way? File systems: avoid complexity. As technically superior as it might be, in this kind of setup ZFS is only going to be resource hog and a maintenance headache; your priority should be having a rock-solid implementation and a reliable set of diagnostic/repair tools in case disaster strikes. Yes. Separate arguments for snapshot support are compelling... but there are alternatives without tackling the additional complexity. That said, the iSCSI approach would work as well with ZFS as something mundane. Snap-shots, of course, are only really valuable for non-archive data... so, in future, I could add a ZFS volume using the same iSCSI strategy.

I much prefer the cron daemon or at daemon to send me the output as email, so I can scroll backwards and forwards through it at my leisure. `man screen` I don't have a man page for screen. This is obviously because it isn't installed. I'm going to assume that you're not being facetious, however I'm amazed you don't know `screen`. Everyone should know `screen`! It's amazing, and I can't believe that if you had tried it then you wouldn't have it installed. I sure you'll wonder how you lived without it. You should try it: `emerge screen` (don't sync just yet) Now type: `screen sudo eix-sync` Wait for syncing to start, then press ctrl-a (together) then the d key. Close the terminal window you're working in, if you like. Open another. Or ssh in from another box. Type: `screen -Rd` You should see all the sync output scrolling past. So press ctrl-a followed by the escape key. Use ctrl-u to scroll up and see what you missed. ctrl-d scrolls down and hitting escape 2 or 3 times exits the scrollback mode. I'm not saying that this is better than having syncs performed by cron job and the output emailed to you. In fact, that's something I've been meaning to get round to setting up here. If I had the output of (sync'd) `emerge -upv world` emailed to me weekly then it might ensure that my irregular habits don't cause me to overlook updates. HOWEVER, this branch of the thread has followed from your surprise that people might run emerge by hand, and your reasons for this (very first quoted above). I'm just saying there's nothing wrong with emerging or syncing by hand. You can easily scroll back and review any output that you need to - in fact the obvious way to do this is using a conventional GUI terminal emulator in a windowing environment. Also: grep PORTAGE_ELOG_MAIL /usr/share/portage/config/make.conf.example This ensures you see all the *important* output of portage, without having to watch the whole darn compiler output, which is pretty useless. You just get an email for every package upon which Portage has a comment to make. Other stuff you can do with `screen`: ctrl-a c- create a new screen window ctrl-a n- next screen window ctrl-a p- previous ctrl-a ?- help ctrl-a- list open screen windows, select one ctrl-a A- name a screen window, see above (capital A) Stroller.

A flash drive (USB key) seems a reasonable strategy - I could even have two containing identical data - so, if the first were to fail then the second would kick in - if not automatically - then after the duff flash-drive is removed.

I just checked, the original screenrc I had when I emerged screen on this system around April has these lines: # Change default scrollback value for new windows defscrollback 1000# default: 100 So it's 1000 already in Gentoo, ten times larger than the default. Still not large enough I think, as we have lots of memory nowadays, don't we. And I often go back many pages, 100 lines is not that much. BTW, I did not know about Ctrl-U/D, after Ctrl-A-Esc I just use PgUp/PgDn to scroll up and down. I prefer to edit /etc/screenrc so everyone has a reasonable large scrollback buffer. Other screen settings go into the user's .screenrc. There's so much that can be set, I'm only using a fraction of screen's features. Another thing I sometimes use: With screen -r user/pid you can join a session that is attached by another user. I am using this sometimes when another person has trouble with their Gentoo installation. I log in into their server, attach to the screen session, and we can both do things in it. screen needs the multiuser USE flag for this, though. Wonko
[gentoo-user] syslog-ng filtering
Hi all,
Has anyone here worked out how to filter out syslog messages using syslog-ng
v3? The old syntax doesn't work (well complains bitterly about performance
and says to use regex), and no matter what I try I cannot get the new syntax
to work :-/ I have a syslog-ng server which logs to MySQL for multiple
clients in a network, however the database just keeps growing with
irrelevant data I'd prefer to just quietly ignore on the server side.
I'm trying to filter out (exclude) messages such as:
(root) CMD (/root/bin/vmware-checker)
and
(root) CMD (test -x /usr/sbin/run-crons /usr/sbin/run-crons )
==
filter myfilter {
not match(regex value(\/usr\/sbin\/run-crons))
and not match(regex value(vmware-checker));
}
log {
source(src);
source(remote);
filter(myfilter);
destination(d_mysql);
};
===
However they just keep coming through the filter (ie: not matching the not
match filter). I've tried escaping the slashes, not escaping them ... even
partial words, but I obviously am missing something somewhere.
Anyone have any ideas?
Thanks in advance,
Ralph

Re: [gentoo-user] Strategy for using SAN/NAS for storage with Gentoo...
1. Are there reliability issues surrounding this technology in Gentoo? My only experience is with a Gentoo-based iSCSI target (ie. server); my clients are windows-based. The system is a low-end Core 2 duo running the latest stable kernel and Iscsi Enterprise Target; I have been running this setup non-stop for a couple of years and it has proven quite stable. iSCSI is designed with a dedicated, reliable network in mind, and in my experience it is quite sensitive to network connectivity issues. It is best used over gigabit ethernet; fast ethernet is ok, too, if you don't care about performace. Avoid WiFi if you value your data (and your mental health) 2. Are there any howtos about putting as much of the file-system as possible onto an iSCSI device. Google root over iscsi. For example: http://wpkg.org/Diskless_/_remote_boot_with_Open-iSCSI I have _not_ tried it. It is an interesting concept, but I think that the OS is better left on a local disk -- the performance penalty is way too great, especially with the king of budget-oriented storage backend you are considering. 3. What's the best (most lightweight) way to expose the disk as a block device. I don't want to manage three fully-fledged Linux boxes. The only software you need is an iSCSI initiator: a minimal Gentoo install running sys-block/iscsitarget is enough. IET allows you to export any kind of raw block device (a disk, a partition, a RAID volume,...) or even a file on a local filesystem. Or perhaps you can look into FreeNAS (http://freenas.org), which is less flexible than a full-fledged OS install but might be enough in your case. Can (cheap) NAS devices be used to export iSCSI to Gentoo? If the NAS device can speak iSCSI, well, yes. 4. What would be the strategy to 'secure' this iSCSI device... it would be a disaster if my WiFi were cracked and my data corrupted from a non-authorised host. iSCSI connections are authenticated with a challenge-response mechanism; in IET you can also restrict access to specific hosts on a per-volume basis. That should be enough if you are not transferring the data itself over WiFi, which is a Bad Thing and should not be done. Snap-shots, of course, are only really valuable for non-archive data... so, in future, I could add a ZFS volume using the same iSCSI strategy. ZFS allows you to take FS-level snapshots -- with iSCSI that would be on the client, onto a network-connected volume, and I don't know what kind of performance implications that has. If you want to take snapshots on the server, my first thought would be to do so at the block level using LVM. No idea if it plays well with IET, though. andrea

Thanks Roy, however they have the same syntax which isn't working on my

filter f_shorewall { not match(regex value(Shorewall)); }
I just tried a single rule (to make sure it wasn't my syntax):
filter killVmMessages {

yet the (root) CMD (/root/bin/vmware-checker) messages still go through?!
log {

I'm really stumped here. All other filters (non regex) works fine though,

Are you able to filter by content?
