 The trouble with this is perl -w doesn't work.

 ... but I thought that on Fedora, /bin was turned into a symlink to
 /usr/bin in F17, so unless you've got some pre-F17 Fedora systems to
 care about, /usr/bin/perl should be fine on Fedora.

 I think you're right, /usr/bin/perl should work just about everywhere.

Re: Domanda su systemd

2014-08-28 Thread emmanuel segura

Ciao a tutti,

Aggiungo qualcosa anchio, anche se penso che il mio contributo non
sara molto utile, comunque leggendo il link che stato postato prima,
nel quale si parla del fatto che si possono avere problemi, non usando
la /usr su una partizione separata, posso chiaramente smentire, adesso
in questo momento sto usando centos 7 con il seguente partizionamento,
e posso dire che non vedo nessun problema



[X@localhost ~]$ df -h
Filesystem  Size  Used Avail Use% Mounted on
/dev/sda814G  5.2G  7.9G  40% /
devtmpfs1.9G 0  1.9G   0% /dev
tmpfs   1.9G  904K  1.9G   1% /dev/shm
tmpfs   1.9G  9.2M  1.9G   1% /run
tmpfs   1.9G 0  1.9G   0% /sys/fs/cgroup
tmpfs   1.9G  1.4M  1.9G   1% /tmp

/dev/sda9   173G   43G  121G  26% /home



Quindi la /usr è sotto la root

 Tempo fa, uno che si presentava in modo poco poco credibile descrisse

 Hi mailing-listers,

 since the upgrade from 9.3 to 9.4, postgresql doesn't automatically start
 at boot anymore.
 I added a symlink to /lib/systemd/system/postgresql.service
 into /etc/systemd/system but I'm not sure this will be enough; is it?
 (3.5 pages of looong mans listed, options in every corner, systemd seems
 to have the art of transforming something formerly trivial to an
 indigestible gas plant).

2014-07-06 16:19 GMT+02:00 Paul E Condon pecon...@mesanetworks.net:
 I am a foolish user of Wheezy. I want to see for myself
 what will happen if I switch to systemd today. I find on
 wiki.debian.org/systemd a document with steps needed to
 install and test systemd, but I have trouble:
 After using apt-get to install the systemd package the
 next step is (verbatim):

 To test systemd before switching to it by default, you can add the following 
 boot parameter to the kernel:

 init=/bin/systemd
 (end verbatim)

 How do I add this parameter to the kernel? I think I must open some
 file somewhere, probably in /etc and edit it with vim or emacs
 (hopefully my choise) and I should place this string correctly within
 that file:

 What file (full path) ?
 What position within the file?

 I think I might be able to guess the position, once I know the path to
 the file, and can read its pre-existing content, but I am not such a
 fool as to assume that the position will be obvious to a fool.

 Thanks and
 best hopes for
 systemd. ;-/

crystal clear on that:

The installgrub command is an x86-only program. GRUB stands
for GRand Unified Bootloader. installgrub is deprecated, as
it applies to the GRUB Legacy boot loader, which was the
boot loader present in Oracle Solaris 11 11/11 and earlier

The add-entry, change-entry and remove-entry subcommands

 Right.  The command is grub-install (these small matters of syntax

Re: Resizing LVM issue

2014-06-01 Thread emmanuel segura

from man resize2fs

   If you wish to shrink an ext2 partition, first use resize2fs to
shrink the size of filesystem.  Then you may use fdisk(8) to shrink the
size of the partition.  When
   shrinking the size of the partition, make sure you do not make it
smaller than the new size of the ext2 filesystem!

i think the correct steps are:

resize2fs /dev/mapper/localhost-home -2G
lvresize --size -2G /dev/mapper/localhost-home




2014-06-01 22:00 GMT+02:00 Miroslav Skoric sko...@eunet.rs:

 Hi,

 I have encrypted LVM on one of my Wheezy machines, and recently noticed
 that /tmp space was too low for one application (In fact it was about 350
 MB and I wanted it to be around 2.5 GB). So I tried to make /tmp space
 bigger while I was mounted and online, but vgdisplay reported no free space
 for that action (something like that):

 sys@localhost:~$ sudo vgdisplay
   --- Volume group ---
   VG Name   localhost
   System ID
   Formatlvm2
   Metadata Areas1
   Metadata Sequence No  9
   VG Access read/write
   VG Status resizable
   MAX LV0
   Cur LV6
   Open LV   6
   Max PV0
   Cur PV1
   Act PV1
   VG Size   297.85 GiB
   PE Size   4.00 MiB
   Total PE  76249
   Alloc PE / Size   76249 / 297.85 GiB
   Free  PE / Size   0 / 0
   VG UUID   fbCaw1-u3SN-2HCy-

 Then I decided to shrink /home for some 2 gig and to add to /tmp :

 sys@localhost:~$ sudo lvresize --size -2G /dev/mapper/localhost-home
 sys@localhost:~$ sudo lvresize --size +2G /dev/mapper/localhost-tmp

 According to df, it did so:

 sys@localhost:~$ df
 Filesystem 1K-blocks Used Available Use% Mounted on
 rootfs329233   219069 93166  71% /

 /dev/mapper/localhost-var2882592   916600   1819560  34% /var
 sys@localhost:~$

 It seems that /dev/mapper/localhost-tmp was about 2.4 GB so I wanted to
 resize newly changed filesystems:

 sys@localhost:~$ sudo resize2fs /dev/mapper/localhost-home
 resize2fs 1.42.5 (29-Jul-2012)
 Filesystem at /dev/mapper/localhost-home is mounted on /home; on-line
 resizing required
 resize2fs: On-line shrinking not supported

 Similar output was with e2fsck:

 sys@localhost:~$ sudo e2fsck -p /dev/mapper/localhost-home
 /dev/mapper/localhost-home is mounted.
 e2fsck: Cannot continue, aborting.


 sys@localhost:~$

 Obviously I should not have done that while being mounted (or did not know
 the proper syntax), however it did not complain with resize2fs
 /dev/mapper/localhost-tmp

 But after the next reboot, it stopped when tried to perform Checking file
 systems:

 /dev/mapper/localhost-home: The filesystem size (according to the
 superblock) is 73481216 blocks
 The physical size of the device is 72956928 blocks
 Either the superblock or the partition table is likely to be corrupt!

 /dev/mapper/localhost-home: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
  (i.e., without -a or -p options)

 Anyway, the other segments of the filesystem were clean, so by CONTROL-D
 it was possible to terminate the shell, so to resume system boot.

 My question is how to solve that inconsistency issue now? At first I tried
 with dumpe2fs in searching for backup superblocks, then with e2fsck -b
 one_of_those_backup_superblocks_from_the_list, but without resolution.
 I mean the inconsistency is not fixed. Probably I do not use e2fsck
 properly even when /home is not mounted. So the machine still keeps
 stopping during the boot at filesystem check, so I have to continue booting
 by pressing CONTROL-D.

 Any suggestion?

 Hi folks!

 Reading some howtos about quota disk I'm not sure about this topic
 (because is very old):

 checking quotas regularly - Linux doesn't check quota usage each time a
 file is opened, you have to force it to process the aquota.user and
 aquota.group files periodically with the quotacheck command.You can setup a
 cron job to run a script similar to the one below to achieve this

 so, I need remount fs without quota, do:

 quotaon -vaug

 e remount with quota?

 Can anyone that use disk quota confirm this thing?

 thanks for help!

 vsftpd is Very Secure FTP Daemon. It does FTP well (cleartext passwords

  users must be chroot'ed to /home/chroot/home/username.
users belong to the chroot group.
their home dir down, need all be group owned by chmgr.
home dir down; should all be chmod 770(dir)/660(files). so user and
  managers (chmgr group) all have rw access to files, and rwx /dirs; with
  other having no rights at all.

  managers ideally chroot'ed to /home/chroot/home.
they can access all username folders, and transfer files in/out of
  each.
they belong to the chmgr group.

 Sounds exactly like a job for the Match directive within a standard
 sshd_config (openssh-server).

Re: Run script for each ssh login

kill -9 $$


2013/11/13 Antonio Paiva arpa...@sci.utah.edu

 Hi everyone,

 I would like to set up an ssh server such that, everytime someone tries to
 connect to it, a script will be run to control certain aspects of the
 connection. More specifically, I want to check if certain conditions are
 met and, if they are not, refuse/abort the connection.

 I found that if a /etc/sshrc script exits, it will be run just before the
 user's shell or command is invoked. However, how can I write the script
 such that if the check fails, the ssh session is aborted? I'm told that if
 the script exits due to an error (say, a syntax error), the SSH session
 continues normally.

 I don't have to use the /etc/sshrc script. If you have an idea of an
 alternative approach that would achieve the same goal, please let me know.

 Thanks.

 The smtpd_* prefixed commands are Server configurations where Postfix is

Re: network/bridging problems

2013-10-02 Thread emmanuel segura

How did you configured eth2? dhcp too? why you tap as bridge port intend of
eth2?


2013/10/2 Ross Boylan r...@biostat.ucsf.edu

 I setup bridging on my system for kvm, but on restart of the host system
 (no guest VM's running) could not ping outside my local network.

 Bringing the bridge down corrected the  problem, but I'm trying to
 understand what is going on, and how I can make networking from the VM's
 work.

 /etc/network/interfaces has (on the advice of a wiki page on Debian and
 kvm)
 auto br0
 iface br0 inet dhcp
pre-up ip tuntap add dev tap0 mode tap user root
pre-up ip link set tap0 up
bridge_ports all tap0
bridge_stp off
bridge_maxwait 0
bridge_fd  0
post-down ip link set tap0 down
post-down ip tuntap del dev tap0 mode tap

 My one connected interface, eth2, was brought up by hotplug with no
 mention in interfaces.

 Originally, with the system up, I added the br0 stanza to interfaces and
 did ifup br0.  This temporarily interrupted my network connections,
 which was not good, but they resumed afterwords.

 This time I restarted the system and found networking non-functional.  I
 could not ping my ISP's nameserver.

 which looked OK to me; that is, ip route seems to show external packets
 should go to eth2, which is the external interface, via the .10 address
 of the router.  But
 # ping 198.144.192.2
 PING 198.144.192.2 (198.144.192.2) 56(84) bytes of data.
 From 192.168.40.102 icmp_seq=1 Destination Host Unreachable

 One difference between the ifconfig above and what I saw before
 rebooting was that before rebooting eth2 had no IP (which seemed odd).

 ifdown br0 also brought eth2 down.  I added iface eth2 inet dhcp
 to /etc/network/interface and did ifup eth2; now I can reach the world
 and see
 # ip route
 default via 192.168.40.10 dev eth2  proto static
 192.168.40.0/24 dev eth2  proto kernel  scope link  src 192.168.40.102

 The operation of bridges and taps is mysterious to me, particularly the
 relation between the two, even after reviewing man pages and various
 other help.  I'd appreciate any guidance.

 Thanks.

 That's what I don't understand: this is booting the Debian Sid kernel, but
 when I boot with the same root parameter with my own kernel it works. Why
 does initramfs see the vg with my kernel but not with Debian's?

 My own kernel is the same version as Debian's but just has the modules for
 my hardware, while Debian's has everything.

 Hi,

 Booting the latest Debian stock kernels stop in initramfs saying that
 /dev/mapper/vgHDB-HDBB does not exist as root device.

 But the kernel that I built myself has no such problem.

 This refers to 3.10.4, and later versions.

 What am I missing?

This workaround is not for you, man mkfs.ocfs2 and look the option

  -T filesystem-type
  Specify how the filesystem is going to be used, so that
mkfs.ocfs2 can chose optimal filesystem parameters for that use.  The
supported  filesystem  types
  are:

   mail   Appropriate for file systems that will host lots
of small files.

   datafiles
  Appropriate for file systems that will host a
relatively small number of very large files.

   vmstore
  Appropriate for file systems that will host
Virtual machine images.

Re: Difficulty configuring kdump

2013-07-29 Thread emmanuel segura

Hello

After you reboot and configure your kdump, before you do the test crash
dump, check if your crash kernel was loaded corretly with grep -i crash
/proc/iomem




2013/7/29 Andrew Walsh awa...@permabit.com

 Hi all,



 I’ve got an issue trying to configure kdump on my debian systems, and I
 was hoping someone could help shine some light on the issue for me that
 might help me get it working.  I’ve done some extensive reading about how
 to configure it, but nothing has been fruitful in pointing me in the right
 direction.  The systems I am trying to get this working on are running
 debian squeeze with the 64-bit 3.2 backported kernel via squeeze-backports.



 Here's the scenario:

 I configure kdump /etc/default/kdump-tools as I would like (I've varied
 the location of /var/crash around in the event that partitioning or
 location had anything to do with it, with no success):

   USE_KDUMP=1
   KDUMP_COREDIR=/var/crash
   DEBUG_KERNEL=/usr/lib/debug/boot/vmlinux-3.2.0-0.bpo.3-amd64
   KDUMP_CMDLINE_APPEND=irqpoll maxcpus=1


 And then update the grub config

   For grub1 (for xen-hosts): Append crashkernel=64M@192M to kernel line
 on default boot
   For grub2: edit /etc/default/grub and append crashkernel=64M to
 GRUB_CMDLINE_LINUX_DEFAULT
 (I’ve noticed that if I keep quiet in there, kdump-tools fails to load
 as well)
   run update-grub
   (If there is a double space before crashkernel in the resulting
 grub.cfg or menu.lst, I noticed that I have to remove it manually)

 On one of the systems (the same one showing the output of kdump-config),
 here is the resulting kernel param in my grub.cfg:
   linux   /boot/vmlinuz-3.2.0-0.bpo.3-amd64
 root=UUID=8135cc05-9b88-4aa1-be74-9c4d687bf956 ro crashkernel=64M



 I then reboot the host and run kdump-config status, which returns Ready
 to kdump:

 # kdump-config status
 current state   : ready to kdump


 This is the output of kdump-config show:

 # kdump-config show
 USE_KDUMP:1
 KDUMP_SYSCTL: kernel.panic_on_oops=1
 KDUMP_COREDIR:/var/crash
 crashkernel addr: 0x330
 current state:ready to kdump

 kernel link:
   /usr/lib/debug/boot/vmlinux-3.2.0-0.bpo.3-amd64

 kexec command:
   /sbin/kexec -p
 --command-line=BOOT_IMAGE=/boot/vmlinuz-3.2.0-0.bpo.3-amd64
 root=UUID=8135cc05-9b88-4aa1-be74-9c4d687bf956 ro  irqpoll maxcpus=1
 --initrd=/boot/initrd.img-3.2.0-0.bpo.3-amd64
 /boot/vmlinuz-3.2.0-0.bpo.3-amd64


 Ensure that I have the sysrq trigger set up correctly by setting it to 1:

 echo 1  /proc/sys/kernel/sysrq

 (This is usually already set to 1, but I still do it to make sure)

 Then I simulate a crash:

 echo c  /proc/sysrq-trigger


 On a Squeeze host, the panic occurs, but nothing else. I have to manually
 reset the machine to bring it back.
 On a RHEL6 host (slightly varied configuration), the kernel dumps the core
 as expected and reboots.

 One thing to also note is that when I have this config in place, sending a
 reboot operation to the system responds as expected, where it doesn’t fully
 reboot the machine, it just simply reloads the running kernel, so it does
 appear that things are half-working.


 I have tried this configuration on several machines, and they all react
 the same way. I've reached out to the package maintainer for the best place
 to ask this question for kdump-tools, but I haven't gotten a reply, so this
 was my best guess.



 I would greatly appreciate any help or insight into where I might find
 some assistance with this issue.

 Thanks.

 *Andrew Walsh*

as you see in the kernel trace, maybe it's kernel BUG, i don't know if
there is an open bug for this, but it can be useful if you try to do the
same thing with an other kernel.

the 3 paraters are passed to function kernel_version_integer, but i see in

You can do it with two different configuration files on the client side.

Thanks

 Hi all :-)

 I've a large network over internet. Some clients connects to server by vpn.

 Now I need setting up another vpn server on other server:

 server1: openvpn server

 so, two machines with one openvpn server each.

 How can I configure clients to connect to both openvpn?

Re: How to disable UTC time?

2013-07-09 Thread emmanuel segura

Hello

If you wanna fix the problem = remove windows :)


2013/7/9 Yuwen Dai yuw...@gmail.com

  I realize this is the sort of answer that annoys me to death when I get
  it...  but why not fix the time on your BIOS clock?

 I did.  As I mentioned in the previous email, I set the BIOS clock as
 UTC time and set my time zone as UTC+8, this works.  My machine also
 has Windows, after I boot into Windows, I found the BIOS clock was
 modified by Windows that set the clock time as local time, i.e. UTC+8,
 after that  I boot into Linux, Linux thinks the BIOS clock is till
 UTC, it add 8 hours again to get the local time,  so my clock is 8
 hours ahead.   To get rid of the interference of Windows, I need to
 disable UTC.

 Best regards,
 Yuwen

I successfully run nfsv4 and drbd in clustered mode.

The main thing to do wrt config files for nfs is pin down port numbers
to specific (rather than dynamic ones) at startup for the rpc suite.
And also switch to UDP rather than transport (solves session issues
during failover) - your clients all need to explicitly ensure they are
mounting with udp options.

Also you need to have the rpc socket file handles on a clustered
filesystem somewhere mounted on both nodes (I use GFS2 for this
purpose as it's easier).

I have heard great things about ceph instead of drbd but haven't tried
it myself yet.

It may be worth clarification to note GlusterFS is not a cluster
filesystem. It is a distributed filesystem. There is a significant
difference between clustered and distributed.

A distributed filesystem such as Gluster is applicable to your needs as
you can add/remove clients in an ad hoc manner without issue. A cluster
filesystem is probably not suitable, because you simply can't connect
new nodes in a willy nilly fashion. None of OCFS, GFS, GPFS, CXFS, etc
handle this very well, if at all. Cluster filesystems require hardware
fencing between nodes. One doesn't setup hardware fencing willy nilly.

Re: how to boot a system with a broken but non-essential LVM VG

2013-05-16 Thread emmanuel segura

Look this
http://www.centos.org/docs/5/html/Cluster_Logical_Volume_Manager/lost_PV_remove_from_VG.html


2013/5/16 Ross Boylan r...@biostat.ucsf.edu

 One of the disks that was in an LVM Volume Group died, as a result of
 which LVM reports an error when the system starts.  I believe because of
 the errors from lvm the boot sequence stops.  After several minutes it
 times out.  At that point a shell prompt appears.   The missing physical
 disk is no longer essential for the system to boot, and the damaged VG
 still has some good volumes in  it, so I do
 vgchange -ay
 which reports errors but activates what it can
 and
 cryptsetup luksOpen /dev/myVG/myCryptRoot CryptRoot
 when I exit the shell the system boot continues successfully.  I'm using
 grub2 on amd64 and a standard initramfs for wheezy.  Note that myVG is not
  the damaged volume group.

 Is there some way I can achieve the same effect without manual
 intervention (except for the crypto pass-phrase) and without the wait for
 timeout?

Re: mdadm devices have the same name after install of Debian Wheezy

2013-04-30 Thread emmanuel segura

Hello John

I'm pretty sure the RAID and LVM are both MD devices but are using the same
name

Ummm LVM is on dm and raid software is on md, try to check your lvm.conf
into your initrd, because i thin the reason of your problem is, the vg was
not  found

Thanks


2013/4/30 John Tate j...@johntate.org

 I installed Debian Wheezy on a computer with two hard drives. Each drive
 has a software RAID partition (RAID1) but the first partition on the first
 drive is GPT and the second drive's first partition is /boot. On the
 software raid is a LVM with root, swap, and home all encrypted. I also
 tried encrypting the whole LVM before that and got the same error.

 I'm getting an error right after grub loads the kernel with mdadm that I
 have two devices with the same name for /dev/md. Here is a screenshot of
 the full error:
 http://media.johntate.org/Pictures/Errors/2013-04-30%2013.15.03.jpg

 I'm pretty sure the RAID and LVM are both MD devices but are using the
 same name. I'm pretty sure this is how I configured my other computer which
 isn't UEFI or GPT but had no trouble with it, suggesting a problem with the
 Debian installer perhaps. I might be wrong though, I can't see what else
 would be the problem. The installer for Wheezy shouldn't even let me make a
 mistake this big.

 How can I fix this? It's strange.

 Edit: I checked /etc/mdadm/mdadm.conf under the initrd using Busybox and
 there seems to be two entries for a md array called mises though I know I
 only created one.

 Thanks again for your help with this.

 I've run 500 pings (-c 500 -i 0) in both directions, and got zero loss.

 Ill try running tcpdump on both servers, and re-testing to check the
 segments.

 Swapping the servers would be extremely difficult ;)  (They are over
 1000k's apart, and one is in an unmanned(majority of the time) data
 centre.

  Sorry, what I meant by this is if every sent segment from B reaches A.
  You can run an instance of wireshark on each host to check this.
  Basically you need to check for packet loss at high speeds (ping could
  be of use if you set the interval to 0).
 
  TCP Dup ACKs are likely caused by packet loss.
  TCP segment of a reassembled PDU is something Wireshark adds since it
  interprets a bit about application layer protocols, and I think it's
  not a reason to worry (I could have understood this wrong, I just
  looked it up).
 
  If it's easy, you could also try swapping the location of the hosts,
  to see if the problem is on the hosts, or on the link.
 
  Hope it helps and post more info if you find any.

Re: lvm2 size of logical volume after lvcreate --size 348g after mkfs.ext3 -m 0 is only 343 gigabytes?

2013-02-14 Thread emmanuel segura

man tune2fs

  -r reserved-blocks-count
  Set the number of reserved filesystem blocks.

be careful with filesystem reserved block, one time i had a production
server with / corrupted

Thanks

2013/2/14 Mitchell Laks ml...@post.harvard.edu


 Hi I am trying to backup a volume which has size 347G. So I thought to use
 lvm2.
 So I created a volumeby

 lvcreate -n test --size 348G my-volume

 I thought I would be giving myself an extra Gigabyte there :).

 then i did
 mkfs.ext3 -m0 /dev/my-volume/test

 then when I mounted the device
 mount /dev/my-volume/test /mnt

 then df -h
 only shows 343G instead of 348G.

 Note that tune2fs shows that I have indeed have 0 reserved blocks
 (ie mkfs.ext3 -mo /dev/my-volume/test is equivalent to tune2fs -m0
 /dev/my-volume/test

 So my question is where have those extra 5G gone to?

 I need to back up a 347.

 So I had tp set it up with 353G to have the correct size.

 Can anyone explain this to me?
 What kind of formula to use to calculate how much space I will need in
 advance for creating the ext3 or in the future ext4 file system? 5G seems
 like a lot.

 Thanks,
 Mitchell Laks

 Typically an application uses storage _via_ filesystem operations;
 opening a file, reading from it, writing to it and etc.

 Is there any instance where an application works with a partition
 directly?  For a hypothetical example, a database application might
 create and use a file system in a storage volume without involvement
 of the OS.  Does any such thing exist in practical use?

 Thanks,   ... Peter E.

Re: /var full

2013-01-30 Thread emmanuel segura

Maybe you deleted the files, but some process are using the inodes

2013/1/30 Bonno Bloksma b.blok...@tio.nl

 Hi,

 I had a problem that generated A LOT of messages in syslog and it grew
 untill the entire /var partition had 0 bytes free.
 The /var/log/syslog file was over 4GB large. I deleted it using a simple
 rm /var/log/syslog command and the file is indeed no longer there.
 The du /var/log -s command shows a decrease of over 4GB so that seems to
 confirm it but

 There are still 0 bytes free on the /var partition as the df command shows.
 root@linutr:~# df
 Filesystem   1K-blocks  Used Available Use% Mounted on
 /dev/mapper/vgroup1-lvroot
4805760   1306860   3254780  29% /
 tmpfs  3058148 0 3058148   0% /lib/init/rw
 udev   3052820   184   3052636   1% /dev
 tmpfs  3058148 0   3058148   0% /dev/shm

 /dev/mapper/vgroup1-lvvar
9611492   9611492 0 100% /var
 root@linutr:~#

 Also there is still no nerw syslog file, probably because the filesystem
 shows 0 bytes free.
 /var is an ext3 partition

 Should I just unmount /var, and run fsck.ext3 /var or is there something
 else I should do first?
 Is there maybe some background process that is still running through all
 inodes freeing up the 4+GB diskspace?

 Bonno Bloksma

 You are using split the wrong way. The regexp shold only be the
 *delimiters*.

 Here's my two alternative ways to accomplish the task:

 # use the match operator with the regexp
 my @l2 = $str =~ m/$re/;
 say scalar(@l2), : ,join(=,@l2);

 # split the string based on the delimiters
 my @l3 = split(/[x+-]/, $str);
 say scalar(@l3), : ,join(=,@l3);

 Both will print the string:

 Hi there!

 I'm using the package krb5-kdc-ldap to use mi kerberos with LDAP backend.
 I've followed the debian and ubuntu documentation and I find some
 issues I can't solve:

 · I fill the LDAP tree using the kdb5_ldap_util as seen in
 documentation. The LDAP server is correctly written.
 · The stash are created, with the neccesary credentials.
 · When initializing the admin interface, with kadmin.local, i get:

 kadmind[26023](Error): Can not fetch master key (error: Cannot
 find/read stored master key). while initializing, aborting

 The same when starting the service in /etc/init.d. In both cases, the
 LDAP server is strongly readed:

 krb5kdc: Can not fetch master key (error: Cannot find/read stored
 master key). - while fetching master key K/M for realm EXAMPLE.ES

 So, I think the options are:
 1) In the LDAP server some information is missing (a bug in
 kdb5_ldap_util?)
 2) There is something I don't understand in the procedure.

Re: Squeeze64: LD_LIBRARY_PATH / ignored or overwritten under X

2012-01-12 Thread emmanuel segura

Try to use /etc/ld.so.conf for load your library

2012/1/12 Denny Schierz linuxm...@4lin.net

 hi,

 I've created a file /etc/profile.d/path.sh

 with:

 LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/jni
 export LD_LIBRARY_PATH

 If you log in on a plain shell, it works, but if you log in via X
 (kde/gnome/fluxbox) and open a terminal (konsole/gnome-terminal/xterm) my
 special path /usr/lib/jni is missing. If you start in a terminal bash
 -l you get the missing path.

 I need /usr/lib/jni for Eclipse (I really hate java), otherwise Eclipse
 doesn't find SVN libs.

 What could be the problem?

Try to do this

set -x

source /etc/profile

like that you can see if you have some syntax error

 nope, Sun Java parses the LD_LIBRARY_PATH variable, so it won't work:

 disable ssh-agent in Xsession/options helps.

Re: can't serve php files in apache2

2010-11-12 Thread emmanuel segura

AddType application/x-httpd-php .php

2010/11/12 Zachary Uram net...@gmail.com:
 Running Debian testing, I installed libapache2-mod-php5, php5,
 php5-common, php5-cgi, php-pear and created a test file info.php
 which is 1 line ?php phpinfo(); ?
 However when I go to http://myserver.org/info.php it prompts me to
 download the PHP file instead of executing it and displaying the
 result. I've tried with firefox and IE and get the same result. Any
 idea how to get this working?

 Hi list!

 I want to copy a lot of files via rsync (about 200GB), but the process
 ends in D state after some time. In /var/log/kern.log I have this error:

 Sep 10 09:26:45 servername kernel: [31527915.475952] EXT3-fs warning
 (device md2): ext3_dx_add_entry: Directory index full!

 Any ideas?

 Server info:

 Many thanks for reply!

 Jakub Jedelsky.

 Hi,

 What's the easiest way to set password for user account via script?
 The most common tool would be fine, even if it means that the password
 has to be clear text.

 Thanks

 You can write passwords directly to /etc/shadow as root, but it's rather
 dangerous to do, but I shouldn't be here to warn you and caution you
 since you should already know all this, on to the example:

 echo user_password|openssl passwd -1 -stdin
 $id$salt$encrypted_password

 root:$1$RsTbBahJ$2NjYxhHostQUasMcczo1T0:14824:0:9:7:::
