Q: 'df' reports partition is full but 'du' shows not full partition -- how to find where the problem
Hello, what would be a best approach for the following situation: You have a web server and monitoring system reports that you short on disk space. You login into web server computer and command 'df' indeed shows that some partition is almost full. How would you resolve the issue if 'du' does not confirm that disk is full. You 'du' all directories in the root of the partition but sum does not adds up to match 'Use%' reported by 'df'. For such situation I would assume that some process holds huge open file which was deleted (for example your web server was compromised). Question: how would you find the process which holds 'deleted' file? Thanks, Andy -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

NetInstaller Wheezy (7.8) on ASUS M4A78A-M/CSM does not see SATA HDDs
Hi, I am attempting to netinstall Wheezy (7.8) on a computer with ASUS M4A785-M/CSM mainboard (BIOS was updated to most recent version 2302 2011/03/18) and WD 2TB SATA HDD. Netnstaller requires network driver (rtl_nic) which I provided on USB drive and the installer gained network access. But netinstaller does not see SATA HDDs (tried SATA in both IDE / AHCI BIOS mode settings -- HDD WD20). Please nudge me in right direction what should be done on my part to make netinstaller to be able see SATA hard drives.

Q: Apache::mod_proxy how implement request forward for image files
Hello,
Can somebody explain how next task can be accomplished? My own attempt
to figure out how this can be achieved wasn't successful.
I do not see any problem with virtual servers. But how to implement in
apache2 through mod_proxy forwarding for image files requests only? And
how on backend virtual server exclude/blocks a requests for all types of
files except pictures?
Create a new Apache VirtualHost that meets the following requirements:
Name: frontend.${IP}.example.com
Port: 80
Document Root: /var/www/vhosts/frontend/htdocs
Using Mod Proxy, forward all requests for image files
(.jpg, .gif, or .png) to the backend server without modifying the URL of
the request
All errors should log to
/var/www/vhosts/frontend/logs/error.log
All access requests should be logged to
/var/www/vhosts/frontend/logs/access.log except for requests for any
files ending in .jpg, .gif, .png.
Backend Site
Create another Apache VirtualHost that meets the following
requirements:
Name: backend.${IP}.example.com
Port: 8001
Document Root: /var/www/vhosts/backend/htdocs
Configure this VirtualHost to respond with a 403 Forbidden
error for all requests for files that do not contain an extension of
.jpg, .gif, or .png
Thank you in advance,
Andy

Help: Ubuntu 12.04LTS/14.04LTS PXE/netboot/preseed - does not initiate installation
Hi,
I stumbled on a problem with Ubuntu installation PXE/netboot/preseed.
OS: Ubuntu 12.04LTS/14.04LTS
I have setup for DHCP/TFTP/NFS which allows me to boot over network
Live Ubuntu and everything works as it should.
Next logical step would be automatic installation by utilizing preseed
file. And here I hit a snag -- Ubuntu copies the file but I do not see
any attempt to start installation (search on internet give multiple
examples and most of them look alike but do not work in my case).
So in PXE configuration file I have next block
LABEL 8
MENU LABEL Ubuntu 12.04 Desktop (i^386) auto
KERNEL Ubuntu/12.04/desktop/i386/vmlinuz
APPEND root=/dev/nfs boot=casper netboot=nfs
nfsroot=192.168.0.64:/var/www/dvd/Ubuntu/12.04/desktop/i386
initrd=Ubuntu/12.04/desktop/i386/initrd.lz auto
url=http://192.168.0.64/preseed/ubuntu/12.04/desktop/i386/preseed.conf
TEXT HELP
Boot the Ubuntu 12.04 desktop i386 auto
ENDTEXT
By selecting this option from PXE menu the computer continues to boot
and at some point it retrieves preseed file from webserver. Shortly
after that boot process starts graphical screen where I can see Install
Ubuntu icon and then process stops.
I am not sure how to troubleshoot this situation and best what I could
find is /var/log/casper.log file which has next content

Is it a bug -- mount does not work on 127.0.0.1/127.0.1.1 interfaces?
Hi, OS: wheezy / squeeze Could somebody explain what wrong? Why mount refuses to mount through loopback interface? The issue can be reproduced in your system with next set of commands root# mkdir -p /exports/home root# cat /etc/exports /export/home 192.168.0.0/24(rw,sync,no_subtree_check) ^C root# exportfs -ra root# mount -t nfs 127.0.0.1:/export/home /mnt Is there a cure for this issue?

Re: Q: nfs server fails to mount own exported resource, but other client able to mount
Hi, the mystery has been resolved -- question how did I not catch it right away? I found that my old Red Hat system and Debian Wheezy/Squeezy resolve computer name into ip address in different ways. Red Hat mount maps computer name to DHCP ip address Debian mount maps computer name to loopback interface My attention was somewhat distracted and I've missed that in this case in /etc/exports a record should look not like /export/home192.168.0.0/24(rw,sync,no_subtree_check) but instead /export/home192.168.0.0/24(rw,sync,no_subtree_check) 127.0.0.0/16(rw,sync,no_subtree_check) The clue was found in logfiles /var/log/syslog.1:Apr 24 10:29:19 vega mountd[1320]: refused mount request from 127.0.1.1 for /export/home (/export/home): unmatched host The mystery is resolved.

I wonder if it is letting you mount as 'nfs' when you supply the IP address, but is not letting you mount as 'nfs' when you try to address the device locally (which doesn't surprise me). While I don't use mount, I do use fstab to mount the device containing our nfs export, locally /dev/md5 /mnt/point ext4rw,auto,users,exec Isn't the 'right' way to mount local filesystems directly as 'ext4' or whatever, and only mount as 'nfs' if the filesystem has to be accessed at another IP address? regards, Ron -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Re: Is it a bug -- mount does not work on 127.0.0.1/127.0.1.1 interfaces? [RESOLVED]
Hi Don, I found what the problem was about half an hour ago -- the clue was found in logfiles /var/log/syslog.1:Apr 24 10:29:19 vega mountd[1320]: refused mount request from 127.0.1.1 for /export/home (/export/home): unmatched host I got confused with my old configuration (Red Hat 7.3) where 'mount' command resolved computer name into DHCP assigned ip address and not to loopback/127.0.1.1 as it happens in Debian Wheezy/Squeezy. Once I modified /etc/exports to /export/home192.168.0.0/24(rw,sync,no_subtree_check) 127.0.0.0/16(rw,sync,no_subtree_check) everything started to work as expected-- 'mount' has changed it's behavior what required an adjustment on my part.

Q: LDAP on Debian easy/short way
Hi, is there an alternative for next book on LDAP (this book is good but quite outdated -- 2003) http://secretoslinux.files.wordpress.com/2010/08/oreilly_-_ldap_system_administration.pdf Particularly I am interested in next 1. [+] installation of slapd (accomplished) 2. [+] configuration of security (SASL/TLS [gnutls/openssl] -- acomplished) 3. [+] creating user accounts (accomplished) 4. [+] libnss and pam (acomplished) 5. [-] integration with samba 6. [-] integration with radius 7. [-] automount (what schema to use? nisautomount / automount) I did search on internet and found many sources for configuring LDAP server. Much of information is or outdated or not complete. Any reference to an URL covering above mentioned points is greatly appreciated. Or if somebody could provide a URL for HowTo: LDAP server on Debian easy/short way your input would be greatly appreciated.

Q: Squeeze - debmirror 1:2.4.5 / Bug #673444 : not fetch Translation files
Hi,
due limited traffic from my ISP (200GB/month) I've decided to make own
mirror for Debian wheeze.
A quick search brought my attention to debmirror utility. After a
couple days of download I had local mirror for wheeze and
wheeze-updates.
Shortly after the mirror was ready I configured Apache to serve files,
DHCP server and preceed.cfg to make automatic installation over
network utilizing PXE boot.
After a little struggle to make everything right to be able install OS
and packages I found that installation process stops to inform me that
i18n translation files are missing in wheeze-updates. My inspection of
wheeze-updates/main directory confirmed that directory i18n is missing.
My further investigation brought my attentions to bug #673444
(Maintainer: Joey Hess jo...@debian.org) in regard missing translation
files.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=673444
So, it looks like Squeezy still has debmirror version which is affected
by this bug.
dpkg -l | grep debmirror
ii debmirror 1:2.4.5
For the moment I've added a block of code to my script to sync mirror
which resolves the issue
-- Begin my_mirror.sh
#!/bin/bash
.
.
#
# Translation files fix
#
# Description:
# Older version of debmirror does not copy a
# directory if file Index is missing. In this
# particular case client will not find directory
# Translation-en as dists/wheeze-updates/main/i18n
# directory misses Index file.
#
# Bugs: #673444
#
# Note:
# Newer version of debmirror relies on Packages.gz
# file instead of Index and do not have this problem.
#
URL=ftp://ftp.debian.org/debian/dists/wheezy-updates/main/i18n/
DIR=here

[ -d ${DIR} ] rm -f ${DIR}
wget -r -nH -P here ${URL}
cp -r ${DIR_TMP} ${MIRROR}

-- End my_mirror.sh --
What is the best way to address this issue? Contact the maintainer? Use
backports?
Sincerely,
Andrew

Re: Q: LDAP - perl script using Net::LDAP and start_tls gives an error
Hi Atle, in my case I am certificate agency (self-signed certificate) and I issue private key and certificate (cacert.pem) as for root CA as for LDAP server (server-key.pem and server-cert.pem) and LDAP perl script client (client-key.pem and client-cert.pem). The script and client run on the same computer (for the moment) and LDAP server private key (private/server-key.pem) and certificate (certs/server-cert.pem) located in /etc/ssl/ directory. CA root certificate (certs/cacert.pem) is located in /etc/ssl/certs directory -- and as recommended I created certificate named using hash value URL: https://metacpan.org/pod/Net::LDAP#start_tls |ln -s cacert.pem `openssl x509 -hash -noout cacert.pem`.0 Client (perl script) has reference to client's key/cert in the script which is stored in sub-directory 'certs' where located the script (certs/client-key.pem and certs/client-cert.pem). At the moment I am not fully grasp why verification of server certificate fails. I am welcome any ideas how to fix it. NOTE: It is my first attempt to program with Net::LDAP and start_tls -- I am in process of learning how it works and how to program to use LDAP over TLS in perl.
