i only do that with rm ;)
and not often either...
Elirips
[slightly OT ]Hello. Has anyone made experience with the performance of intel Atoms CPUs with linux? I'm thinking of buying a mini-pc, 2GB Ram with an intel atom 300 and use it as workstation with openoffice, firefox, mailing. Any experiences made with it?
sbpaul
ah...lovely
everything nice and organized
stage2
Elirips: with your software requirements, no problem, only problem with a netbook is screen resolution and running virtual machines
cybor0
lautriv unknown filesystem type linux_raid_member and /dev/sda1 is 0x83 now
stage2
Elirips: as well as keyboard size, some programmers say its hard to get used to
Elirips
stage2, thank you! No, don't need a netbook, just a small computer. thought first about a HP small form factor, but its double the price..
lautriv
cybor0, check if mdadm is running (and stop it)
ananke
mdadm is not a service :)
stage2
Elirips: well the atom is great, but like i said, its kinda slow for virtual computing
ananke
mdadm -S /dev/array will stop it
lautriv
ananke, ok, i meant the mdX but i guess he know
stage2
Elirips: but ive seen quake3 run on atom , if that helps
cybor0
mdadm -s /dev/array ??
Elirips
stage2, indeed, that makesme happy :) still should have that cd somewhere.
lautriv
cybor0, -S == stop and array == your raid
PingFloyd
cybor0: commands are case sensitive
cybor0
yes sorry but when i cat
/proc/mdstat
Personalities : [raid1] unused devices: <none>
toki
where can one find info on snmp ? :)
lautriv
ananke, btw i found the problem with ldap, there was a security hole regarding ssl-certs since vers. 2.3 maybe you should check yous too (one can break in if there is a cert with /0 in CN) so they recompiled for gnutls only (not affected)
go|dfish
toki: wikipedia
cybor0
udo mdadm -S /dev/sda1 mdadm: /dev/sda1 does not appear to be an md device
Guest35241
help
lautriv
cybor0, such raids named /dev/md* instead and it may be started because the former 0xfd
golubeff
hello :)
i want to merge three transparent png into one within imagemagick. how do i do it?
linduxed
how much swap would be optimal for a netbook with 1 GB RAM?
PingFloyd
lautriv: a distro worth a crap will backport security fixes for older versions of software they support in their distro
golubeff
linduxed: 1gb is okay
koala_man
linduxed: 1GB
lautriv
PingFloyd, just think before write, it's disabled because not fixed today
linduxed
1 GB it is then
thx
cybor0
i don't have device /dev/md*
levice
lautriv
lautriv
cybor0, did you reboot after change to 0x83 ?
cybor0
no
lautriv
cybor0, this is mostly needed by the hdd itself to make the change permanent
ima
do ubuntu packages work in debian?
nocturnus
http://www.cups.org/newsgroups.php?s20330+gcups.general+v20349+T0 <--- help me with this please
frogzoo
ima: don't do it
frogzoo
ima: well, unless you know what you're doing
lautriv
ima, may but must not because ubuntu has other dependencies
ima
Ah okay, I'll just build it then
Thanks
Martineo
is there a canonical way to find out a programs version number?
mordy
i'm not particularly impressed by opensuse so far
except of course that i think it looks pretty
lautriv
PingFloyd, that's no news and the current fix is nothing else changing the cipher to gnutls
stage2
not even worth it, its like too much code
PingFloyd
lautriv: I think it is safe to say that ananke is probably smart enough to be running a distro that supports security backports.
cybor0
lautriv so i have changed the filesystem to 0x83 but i can;t mount it
lautriv
PingFloyd, why have you to mix up things if you don't understand the context, i am sure ananke is capable of doing this but what in case of a given certification ? shut up and write your desired html-man-pages insted
cybor0
disk is 0x83 but when mount i have mount: unknown filesystem type 'linux_raid_member'
PinkFloyd could you help
someone could help
mae_tae
can i implement vlan in linux
cybor0
lautriv ??
mordy
mae_tae: linux will keep the tags if that's what you mean
lautriv
cybor0, are you sure it was Raid1 and created by mdadm ?
mordy
i think iproute also has some options for vlans but not sure
cybor0
i think it is raid1
when i first connect disk to my pc i have Linux raid autodetect
lautriv
cybor0, plz pastebin dmesg and the content of this ->"mdadm --examine --scan >textfile"
cybor0
but remember taht know i change the linux id
swift
hi guys
cybor0
of tahat fdisk
swift
where can i get infor on mounting CIFS shares in linux?
cybor0
to 83
frogzoo
swift: ldp.org
tldp.org sorry
stage2
lol
PingFloyd
lautriv: I don't need to write html man pages, because they already exist. You want to talk about clouding context. hypocrite.
Guest35241
quit
lautriv
PingFloyd, i know about those but that was your own suggestion. whatever i'm not interested about your comments
cybor0, moment.........
PingFloyd
lautriv: then why the snarky BS the other day? Other than than trying to seem elitist?
cybor0
ARRAY /dev/md3 UUID=fc9084f2:4eb2d3fb:da371cde:044b019b
lautriv that is from mdadm
swift
couldnt find much on tldp.org
easytiger
my virtual machine isn't getting a hostname from the DNS server, is there a way to force this without getting access to the dns server?
or rather setting it with the dns server
zaoul_
Small survey... anyone use joe?
lautriv
cybor0, pastebin blkid
PingFloyd, mans have to be readable on the lowest level DOT.
cybor0
lautriv what ??
lautriv
easytiger, DNS resolves hostnames, if you need one for your local machine on runtime it's dhcpd doing such stuff
cybor0, type blkid and pastebin its output
cybor0
/dev/hda1: UUID="6635cec5-269e-41a9-ba8c-b08eebd93f8e" TYPE="ext3"
/dev/hda5: UUID="5d6c376e-121a-4422-a08d-2bbd639229cd" TYPE="ext3"
/dev/sda1: UUID="fc9084f2-4eb2-d3fb-da37-1cde044b019b" TYPE="linux_raid_member"
/dev/hda3: UUID="a748edcc-ec16-4054-a05e-d6873b6e63de" TYPE="swap"
easytiger
lautriv, indeed, however physical machines hostnames become available to other network clients on boot, but VMs bridged to the network don't
lautriv
cybor0, you see that sda1's UUID is the same like your md3 and so your half-raid is captured ny linux, you need to mdadm -S /dev/md3 again
cybor0
but when i type this mdadm -S /dev/md3
error opening /dev/md3: No such file or directory
lautriv
easytiger, i need some clarification.........do you wish to receive an own hostname or just miss that others don't see yours on the nameserver ?
alabd
hello , why sometimes hardware work with a better quality in GNU/Linux rather than windows , dialup modem or sound or maybe graphic ?
cybor0
lautriv so what is going on ARRAY /dev/md3 is but when type mdadm -S /dev/md3 no souch file
lautriv
cybor0, ls -al /dev/md* ?
cybor0
nothing
lautrv empty
lautriv
cybor0, try mknod /dev/md3 b 9 3 and stop again
cybor0
mdadm: stopped /dev/md3
lautriv
cybor0, now retry mounting sda1
cybor0
oki
this same
mount: unknown filesystem type 'linux_raid_member'
lautriv
cybor0, thy may happen because the persistent superblock info......tell me distro and version
cybor0, maybe you created partitions inside your raid ?
cybor0
i don't make this raid so i don;t know
lautriv
cybor0, do you have enought space for the whole disk anywhere ?
cybor0
no
but i have second disk of that mirror
lautriv
cybor0, try to cfdisk /dev/sda1 instead /dev/sda to see if you have sub-partitions
cybor0
nothig inside
and cfdisk /dev/sda have sda1 inside
c_schmitz
hi, I would like to tail -f a log file but only show lines that contains certain words - is that possible at all?
lautriv
cybor0, ok, 3 choices left..........a.)reboot and check existence of /dev/md3 (rrecreate if not) then mount md3 instead sda1 b.) grab the second raid-member and backup before destroy c.) fsck /dev/sda1 (risky because you don't know the right fs
c_schmitz, tail -f log | grep word
c_schmitz
tahnk you
cybor0
so i can't check disk type of that raid
when i don't know what it is
fsck /dev/sda1
fsck from util-linux-ng 2.16.2
fsck: fsck.linux_raid_member: not found
fsck: Error 2 while executing fsck.linux_raid_member for /dev/sda1
lautriv
cybor0, i said risky because you need to "force" it
cybor0
hm
ok so when i connect second disk i can;t check file type system
lautriv
cybor0, but this way, your autostart know the right by default
bronb
not sure if it's the right channel... I been wondering regards "hash collision", I've read about the subject, but the bottom line I got... that every hash has collisions, it's a matter of possibility/attempts... so my question is this, the only concern is the abuse of a collision security wise? which means, human-oriented attack? or the problem is real for the wild too, of file indexing, and so?
frogzoo
the issue is the difficult of crafting an exploit that also has a hash collission
you can create another file that md5's the same as a library file, but can it actually do anything?
bronb
frogzoo: well my concern is actually about the application-fault level, rather than human-oriented attacks/exploits
frogzoo
and if the file has to be also the same size, it's pretty much impossible
koala_man
bronb: there have been systems that assume hashes are unique, and there are doubtlessly many more in production
bronb
koala_man: oh, so it's not bulletproof, and that's it?
frogzoo
longer hashes
bronb
koala_man: the chances are so low - so nobody care?
crios
need some help with virsh. I've started virt-install with --nographics param, received "reconnect" message, but when I try to connect to my guest OS, it just hangs with "Escape character is ^]" message. My system is CentOS 5.4 with kvm on it
koala_man
bronb: people care, but sometimes it's considered acceptable and sometimes people don't know any better
angel-tsankov
how can I make a flash dongle bootable
carltonb
greetings all
koala_man
bronb: you are very unlikely to find collisions in real files though, so when you do, it's probably an attack
bronb
koala_man: so let me ask you this, hashes are being used to optimize/manage huge systems - the only way to make it 100% bulletproof, (100%), is not to use any hash at all?
koala_man
bronb: depends on the use. in bittorrent, you can't realistically avoid it. in file indexing, you can
bronb
I'm not sure the use of bittorrent, but why you can avoid it during file indexing?
nocturnus
http://www.cups.org/newsgroups.php?s20330+gcups.general+v20349+T0 <--- help me with this please
RickRocK
how to know how centos if i have ffmpeg installed ?
koala_man
bronb: you use the hash to reduce the number of possible file candidates, then you do the long check to see if the files are actually equal
bronb
koala_man: heh, that's -exactly- my problem.
crios
RickRocK: that suppose to mean something?
bronb
koala_man: so basically you're saying it's ok to enjoy the hash as long as it's a sole member, but matching a hash - with 100% accuracy, can't be done. (yes, I know it is possible to double hash, and so on...)
koala_man
bronb: pretty much.
bronb
I wonder if the current weakness of the hashes are algo related, or could easily be avoided with a longer hash
ddrj
hey guys got a question, i currently have 3 pc's at home that run windows and use the shared folders via network. i was wondering if i added a 4th box which was linux, would it be able to connect to this network, would windows see this pc in it's My Networks? and would the linux box be able to share files with the windows pc ?
ah nm, i think i found my answer: Samba
zcram
ddrj: Yes, and it works rather well once you've set it up right...
ddrj
ahhh ok good :D

Anyone have any success with ATI drivers in Slackware?
Shambat
having some problems with a usb wifi adapter on my ubuntu-arm installation ... my messsages file says the device is loading: "usb 1-1: new high speed USB device using orion-ehci and address 2" but wlan0 interface wont come up ... getting the error: wlan0: ERROR while getting interface flags: No such device
lautriv
(Action) brings reisio a coffee .....heyda :-)
Shambat, do you have all modules and firmware ?
reisio
lautriv: oh, thanks :)
Shambat
lautriv: yes I have modprobed the module for the chipset and put the firmware in /lib/firmware/zd1211 ... where zd1211 is the chipset
lautriv
Shambat, also wireless-tools installed ?
Shambat
lautriv: yeah
bronb
koala_man: one more question if I may... if you had to choose between 1 hash of SHA512, or 2 hashes of md5+SHA1 ... which would you choose?
lautriv
Shambat, give it a simple iwconfig maybe you have another devicename
Shambat
lautriv: nothing there other than lo and eth0
lautriv
Shambat, dmesg || syslog ?
Shambat
lautriv: cant see anything special other than messages that the driver is loaded
swift
guys, i really need help with CIFS share mounting on cifs
please help
reisio
swift: subspace!
swift: going to have to be much more specific
lautriv
Shambat, at least dmesg should show "uploading firmware from..." after the module
swift
oops, my bad... cifs share mounting in linux
reisio
swift: going to have to be much more specific
ananke
swift: 'in linux' doesn't specify it at all. what's the actual problem?
swift
i need to mount f\cifs shares(network shares) in linux
reisio
swift: going to have to be much more specific
swift
reisio, i need to mount windows cifs network shares on y ubuntu -server 8.04 lts version
Shambat
lautriv: how can I check if the firmware is being loaded? I see no such message in dmesg
lautriv
(Action) has to take chicks from school....brb
rogue
Could anyone verify if redhat 2.6.18-92.1.10.el5 has pulseaudio?
swift
ananke, on my ubuntu server, i need to mount cifs network shares
reisio
swift: and you've already tried... what?
swift
nothin actually, i have no idea how to do this :D
rogue
Wulf: you use rh?
Wulf
no.
