Evolution
Where's my coffee!
i mean.. hey man.. how are you?
:-P
Fiver
(Action) is now known as Darwinism
I don't drink coffee. Get it yourself, biatch. ;b
I mean.. good man! how are you?
w1z3r
is there anyway to optimize sysctl on centos..
I got Dual xenon 3.2 with 2GigE ram
centos 4.4 /2.6.9-42 smp kernel
connected on Intel 1000Pro to 10GigE port
but libpcap drops %169 packets
Evolution
w1z3r: you mean like adding or changing options in /etc/sysctl.conf and then running sysctl -p to read in the new values
no... can't think of a way..... :-P
w1z3r
:)

hehe
puzzled
hi
cmorland
Is there a way that I can recover deleted files from an ext3 partition? I know the simple answer is no but I was wondering if anyone has had any success restoring files using l337 skillz?
Zathrus_
cmorland: you can mount the disk as a raw device and grep the entire damn thing.
cmorland: that's the only way.
         

cmorland
heh
Fiver
it has been done, but the longer you wait to take the drive offline, the more likely your data has been written over
cmorland
its close to 1TB
orc_orc
cmorland: coroners toolkit as well may be useful
cmorland
i mounted it ro right after I noticed it
Fiver
good
Zathrus_
cmorland: trust me, I know your pain.
cmorland
I'll check out coroners toolkit
I tried FIRE but that wasn't that great
pablus
morning
cmorland
thanks for the tips guys
Zathrus_
TCT was tested with the following systems: [snip] RedHat 5.2, 6.1, 7.3 -- heh.
cmorland
sounds like ext2
Zathrus_
well, ext3 really is ext2 + journal
orc_orc
tct will handle it
cmorland
ya, the problem is that deletes are destructive in ext3 to keep the filesystem consistant
Fiver
treat it as an ext2 partition and rebuild the journal with tune2fs when you're done
HRDaves
aye, isnt there a centos site that shows HDD controller compat?
orc_orc
HRDaves: no - look at the upstreams HCL
HRDaves
i have a Promise SATAII150 TX4, and i wanna know if it works in the latest kernel
Zathrus_
cmorland: there's a useful link on the main page that you may wish to read.
         

HRDaves
upstreams?
orc_orc
(Action) looks at 'Promise' and reads no further
Zathrus_
PNAELV
HRDaves
hey, i work with what i have handy
cmorland
Zathrus_: link?
Zathrus_
cmorland: google has it as first hit
HRDaves
the SATA controller on this gigabyte barebone is completly garbage-- so i really need to put a secondary controller in there asap
Zathrus_
for orc_orc's suggestion
Lam
Zathrus_: you're wrong in this, ext3 differs from ext2 in the way deleted files are handled
Zathrus_
Lam: Yes, cmorland mentioned that. I sit corrected.
Lam: this is also why the ext3 devs say "you're screwed"
HRDaves: what particular feature are you looking for that makes the GB controller "garbage"?
pablus
One question: why was impossible to install centos 4.3 on my Soyo motherboard, attach the manual --> http://cardi.igeofcu.unam.mx/techdocs/Soyo_M5EH1011.PDF
Zathrus_
oh my... I hope you don't have much free space on that drive. They recommend 220% of the free space be available for recovery.
pablus
but for another hand, I can to install fedora core 5
why this?
Zathrus_
Centos isn't Fedora Core.
pablus
ok
I undersatnd
but... what happens with installs?
fedora core 5 is ok, but centos 4.3 nothing
cmorland
Zathrus_: I have another set of drives that I am restoring to
pablus
also I've tryed with whiteboxlinux 4.0 and nothing
orc_orc
pablus: ship the hardware to me and I will test for $200 and advise --
HRDaves
Zathrus_: we have two of these barebones, both get random IO errors
moved the same drives from one to a new box, and the IO errors went away
pablus
orc_orc: is very very strange
HRDaves
yes, i replaced the cables and bleh
Zathrus_
HRDaves: ew. Have you updated the BIOS?
pablus: no it's not. The kernel in FC5 is much more recent. You clearly don't have supported hardware.
orc_orc
no, pablus, you are asking for a result which requires experimentation and testing -- I offered to do what you seem to not want to do ;) jijijiij
Zathrus_
HRDaves: and what board is this?
pablus
orc_orc: severals years ago also I installed suse linux professional 7.1 and cero problems...
HRDaves
a gigabyte barebone, lemme go check the model
osity
(Action) would like to confess to Evolution that it's true, he makes millions with his advanced Centos skills.
pablus
(Action) send to orc_orc argentine money :D patacones ha ha ha ha
Zathrus_
send oil.
orc_orc
pablus: now is this interesting to entos -- go experiment, or send me the hardware and a check, and find out; or ask the mailing list --
pablus: FOREX transaction is all right with me
pablus
orc_orc: ha ha ha
HRDaves
Gigabyte GC-BA12U
couldnt tell if that was the backplane model or the mb though-- i think they wanted to save a few pennies and not waste ink on the pcm
pcb
osity
is there a limit to how many directories you can mount on a different drive in linux?
cmorland
ok, my machine now has 2.5TB time to give this a shot
(Action) crosses fingers
HRDaves
oh you should be able to use debugfs to undelete files, btw
Zathrus_
osity: that didn't parse.
HRDaves
debugfs /dev/whatever
cmorland
yes... I can see them with debugfs
but there is no inode info
I have the block info but I have not figured out how to copy thatto a new inode...
Zathrus_
HRDaves: there don't appear to be any GB boards with that moniker.
cmorland: did you look at the coroner's toolkit page? And the page they had on undeleting?
HRDaves
yeah. give me a sec to lookup the model# from the invoice
FIR[3]
i'm trying to compile something and i keep getting "C++ compiler cannot create executables" when i run configure, can anyone help?
cmorland
Zathrus_: I am about to try that method
it looks almost too simple!
orc_orc
FIR[3]: as root: yum -y install gcc-c++
osity
Zathrus_: what do you mean that didnt parse? you didnt understand the question?
FIR[3]
that seems to work :) now how to i install ncurses
Zathrus_
osity: yes.
orc_orc
FIR[3]: lather, rinse, repeat -- search for stuff using: yum list '*whatever*'
FIR[3]
k
Zathrus_
(Action) notes that orc_orc is feeling kindly this morning
FIR[3]
thanks alot :)
orc_orc
Zathrus_: too lazy to be a proper BOFH ;)
osity
Zathrus_: i have my home directories on a totally seperate set of raided drives.... i want to do that with other directories (on the same raided drive)
i was told that it could get messy.
i wanted to know why?
kurtis
Greetings all, I was just wondering if anyone knows anything about the relase shedule for CentOS 5 since RHEL 5 beta 1 is out in the wild.
andresmujica
hi
i wonder what gui packages come with the centos 4.3 server cd??
HRDaves
ok, the model is GIGABYTE GS-SR168
andresmujica
i usually don' t put any gui on the servers, but i'm wondering if with the server install could be a good practice...
HRDaves
funny enough, newegg doesnt sell it anymore, they removed it from their inventory a week after i got them.. so the things are plagued.
Edward123
hey
okay so i want my server to consult dhcp for it's IP but i want to choose my nameservers manually. how do i do that?
if i make changes to /etc/resolv.conf, as soon as network is restarted or the machine restarts it's reset back
Evolution
Edward123: dhclient.conf
Edward123
brilliant
thanks
(Action) saunters back into the other room
not sure if you were following the story earlier Evolution but i've got that fat dell up and running
Evolution
I wasn't.
I just drive by here occasionally whilst at work and avoiding tasks
Edward123
driveby helpings
Evolution
or mockings. whichever is appropriate
Edward123
so my system doesn't seem to have created a dhclient.conf in /etc - is that the usual place? should i generate one? i checked out man dhclient
Evolution
if you don't have one, you can generate one. check out /usr/share/doc/initscripts-7.93.25.EL/sysconfig.txt for the intarweb script options
or man dhclient.conf
there's all sorts of nifty stuff you can do.
Edward123
(Action) mans
osity
Evolution: how did you know i make millions with my advanced centos skills?
(Action) boasts about the 1.47 brazillion dollars in his bank account ( all due to centos ,of course!)
andresmujica
Hi, i'm planning a sendmail implementation. And i want to use ldap. Anyone has some documentation link that i can use >
do you consider using LDAP with sendmail like a good practice?
cannonball
andresmujica: Using LDAP with any MTA is a good practice as far as I believe.
Edward123
okay
i'm back
andresmujica
yeap, i' m reading on that....
what do you think about integrating with Active Directory.. too hard? or is feasible?
Edward123
so yum search is working, which implies that my machine has access to the internet, but links isn't actually loading any webpages?
cmorland
you can sync your LDAP directory with AD.@ppl3Tr33#
lol
time to change that password
osity
what are you changing the password to?
cmorland
r00tm3N0w
Evolution
his active directory domain it would appear
osity
haha
cmorland
