• How do I improve my incremental-backup performance?

  - by Alistair Bell

  I'm currently using the traditional rsync+cp -al method to create incremental/snapshot backups of our server tree. The backups are going onto a pair of eight-disk towers connected to the backup machine (a Sandy Bridge machine with 16 GB of RAM, running CentOS 5.5) via four eSATA connections (four disks per connection). Each disk is a regular 2 TB disk, so we have 32 TB of disk space connected to the backup machine. We're backing up about 20 TB of data on the servers with this. The problem is that each daily backup is taking more than 24 hours, and the real time-killer isn't the actual rsync, but the time it takes to perform a cp -al of the tree locally on the backup machine. It's taking more than 12 hours just to make the shadow copy of the tree, and as far as I can tell the performance backlog is at the disk (top shows the cp using a lot of RAM but not a lot of CPU and mostly in uninterruptible-sleep state) We have the server data split into four major volumes (and a few minor ones), and each of these backups runs in parallel (with some offsets in the cron to try to get some disks' cp done first). There are two volumes on the backup drive, both striped LVM volumes of 16 TB each. So obviously I need to improve the performance because it's unusable as it stands. The first question is: when CentOS 6 comes out, with support for btrfs, will making snapshots of subvolumes with btrfs substantially increase this performance? The second is: is there a way, with ext3 or something else supported in CentOS 5 or 6, to 'encourage' it to put the directories/inodes in one part of a volume (which could happen to be the part that's on an SSD, via LVM) and the files in another? That would presumably solve the problem, but I don't know of ways to hint ext3 like that.

• PAM Winbind Expired Password

  - by kernelpanic

  We've got Winbind/Kerberos setup on RHEL for AD authentication. Working fine however I noticed that when a password has expired, we get a warning but shell access is still granted. What's the proper way of handling this? Can we tell PAM to close the session once it sees the password has expired? Example: login as: ad-user [email protected]'s password: Warning: password has expired.

• Nginx with PAM authentication through pam_script

  - by Envek

  Have anyone set up such a configuration? It's not work for me. So, I've installed nginx-extras on Ubuntu 12.04 (it's built with PAM module), and write to site config: location ^~ /restricted_place/ { auth_pam "Please specify login and password from main_site"; auth_pam_service_name "nginx"; } Afterwards, in /etc/pam.d/nginx: auth required pam_script.so dir=/path/to/my/auth_scripts And wrote simplest /path/to/my/auth_scripts/pam_script_auth (also I've tried to write complicated scripts) #!/bin/sh exit 0 # should allow anyone Doesn't work. The script is launched (I've wrote full functional script, that successfully executes, check credentials, writes to its own log and returns correct exit code, and executes noticeably long). But no access granted. Only rejected. In /var/log/nginx/error.log appears next record: 2012/09/13 10:44:42 [alert] 1666#0: waitpid() failed (10: No child processes) If I'm specify in /etc/pam.d/nginx: auth required pam_unix.so and grant for www-data user right to read /etc/shadow, unix authorization works fine. But script auth doesn't work. Can't understand, where is trouble. In nginx module, or in pam_script module.

• Chmod 644 on /etc/ any way to fix?

  - by DazSlayer

  I tried to tab complete something and I guess it wasnt there. I know you are not supposed to set the permissions to /etc/ like that, but my permissions seem to be all messed up. whoami prints out cannot find name for user ID 1002 and I cannot cd into /etc/ anymore. passwd and shadow use 640 and 644 so I am not sure why this is a problem. Regardless, is there any way to fix this? The command run was sudo chmod 644 /etc/ I have no name!@vpn-server:/$ whoami whoami: cannot find name for user ID 1002 I have no name!@vpn-server:/$ cd etc bash: cd: etc: Permission denied I have no name!@vpn-server:/$ ls -al etc d????????? ? ? ? ? ? . d????????? ? ? ? ? ? .. d????????? ? ? ? ? ? acpi -????????? ? ? ? ? ? adduser.conf I have no name!@vpn-server:/$ sudo su sudo: can't open /etc/sudoers: Permission denied

I have run "sfc", no problems. There are no Device Errors in Device Manager. I have also run "vssadmin list writers", no problems. Whats going on??? Would it be a good idea to re-install Windows 7?

• My EliteBook is not auto picking 1080p for external monitor, poor display on forcing

  - by Griever

  I'm connecting my Samsung LED S22A300B to my HP EliteBook 6930p through VGA out. Laptop has Intel 4500MHD video card. I have latest drivers installed for both card and monitor. Only 800x600 and 1024x768 are shown. A lot of other people get this problem when they use it with docking station as discussed here. But I am not using any docking station. The monitor works great with my desktop though. As advised on the aforementioned page, one of the things I tried was to force the resolution using Intel's "custom resolution" feature. I installed PowerStrip on my desktop and copied advanced timing values(front/back porch,sync width, etc.) from there and then used the same values while defining a custom resolution in my laptop's Intel graphics utility. As a result, I got the 1080p resolution but the display is poor. Text has some weird colored shadow and sometimes on images too. What should I do?

• How do photoshop slices and layer comps interact?

  - by Steve314

  I'm interested in using Photoshop (I have CS2) for some user interface design. I was hoping to be able to use slices and layer comps to mark out particular elements, and use Javascript scripting to export multiple graphics files and text descriptions (positions and sizes of slices mainly) that will be used by my program. My problem is that I've never used Photoshop for web design, or otherwise used slices, and I'm not confident that I understand how they interact with layer comps. This is what I believe (and hope) is correct... Manual slices aren't affected by layer comps in any way - they aren't saved as part of a layer comp. The same manual slices will be active irrespective of which layer comp is selected. Layer-based slices aren't directly affected by layer comps, but they are indirectly affected in that the layer comp saves details of layer position and style. Thus selecting a layer comp may move a layer and change its style, affecting the location and size of its layer-based slice, or may effectively disable the slice by hiding the layer. Automatic slices aren't directly affected by layer comps, but are indirectly affected due to changes to the layer-based slices. So, layer based slices (which are my main interest) may move, may change size (to accomodate a style such as a drop shadow), and may be effectively disabled by the layer being hidden. Other details (and all details of manual slices) will remain constant irrespective of which layer comp is active. Is that correct?

• NIS user not being added to NIS group

  - by Brian

  I have set up a NIS server and several NIS clients. I have a user and a group on the NIS server like so: /etc/passwd: myself:x:5000:5000:,,,:/home/myself:/bin/bash /etc/group: fishy:x:3001:otheruser,etc,myself,moreppl I imported the users and groups on the NIS client by adding +:::::: to /etc/passwd and +::: to /etc/group. I can log in to the NIS client, but when I run groups, fishy is not listed. But getent group fishy shows that it was imported correctly and lists me as a member. And if I do sudo su - myself, then suddenly groups says I am in the group! I also had nscd installed, and the groups worked correctly for a while. It seemed like after being logged in for a while, I would silently be dropped out of the group. If I restarted nscd and logged in again, then the groups worked correctly...for a while. There are no UID or GID conflicts with local users or groups.

• samba "username map" stopped to work

  - by Kris_R

  It was time to upgrade our group server (new HDs, problems with old installation of DRBD, etc..). Going as usually for CentOS i upgraded whole system from 6.3 to 6.4 The later one came with samba 3.6 as the old one was 3.5. I transferred most of users by copying /etc/password, /etc/shadow and samba accounts with pdbedit. Homes were on nfs-drive. The translation of unix accounts to samba accounts are located in /etc/samba/smbusers. Strangely enough on some windows clients there was problem to connect to samba-shares. In one case the only thing that worked was, instead of giving windows name, to use the unix account. In another one, it was possible to mount network drive and to open it in Windows Explorer, however other applications like "Total commander" at the attempt of opening this drive gave the message "Cannot connect to z:" (sometimes at this moment user/pass were requested). The smb.conf has following entries: [global] security = user passdb backend = tdbsam username map = /etc/samba/smbusers ... [Kris] comment = Kris's Private path = /SMB/Users/Kris writeable = yes read only = no browseable = yes users = krisr printable = no security mask = 0777 force security mode = 0 directory security mask = 0777 force directory security mode = 0 force create mode = 0775 force directory mode = 6775 The smbusers: # Unix_name = SMB_name1 SMB_name2 ... krisr = Kris Of course testparm runs without any errors. I was used from samba 3.5 to outputs of form Mapped user Kris to krisr. Nothing like this happens now. Just message check_sam_security: Couldn't find user Kris in passdb. I read on web that some guys had problem with 3.6 and security = ADS, but these were not helpful for me. I'm seriously thinking about downgrading back to samba 3.5 but before this step I wanted to ask if somebody knows the solution of these problems. p.s. i've asked this question at serverfault but no answer came. Maybe I have more luck with this forum. Sorry for duplicate if any of you reads both.

• Conky starts above windows in Ubuntu Maverick

  - by DesertIvy

  Hey guys, I did not run into this problem until I upgraded my Ubuntu box to Maverick Meerkat (10.10). Basically, whenever I start my computer, conky runs as expected, except it gets drawn over any windows that I load (see screenshot). To fix this for a single session, I simply restart conky by running killall conky; conky in a terminal. Conky gets re-drawn below active windows (namely, only appearing on my desktop), and does not have the border/drop-shadow, but I have to do this every time I start a new session. Is there a simple way to fix this? I have a small shell script that I run on startup, but it does not seem to solve the problem. #!/bin/bash sleep 10 && conky; sleep 5 && killall conky; conky; Below is the non-text part of my .conkyrc file. # Conky settings # background yes update_interval 1 cpu_avg_samples 2 net_avg_samples 2 override_utf8_locale yes double_buffer yes no_buffers yes text_buffer_size 2048 #imlib_cache_size 0 temperature_unit fahrenheit # Window specifications # own_window yes own_window_type override own_window_transparent yes own_window_hints undecorate,sticky,skip_taskbar,skip_pager,below border_inner_margin 0 border_outer_margin 0 minimum_size 200 250 maximum_width 200 alignment tr gap_x 220 gap_y 280 # Graphics settings # draw_shades no draw_outline no draw_borders no draw_graph_borders no # Text settings # use_xft yes xftfont caviar dreams:size=8 xftalpha 0.5 uppercase no temperature_unit celsius default_color FFFFFF # Lua Load # lua_load ~/.lua/scripts/clock_rings.lua lua_draw_hook_pre clock_rings

• Failed to su after making a chroot jail

  - by arepo21

  On a 64 bit CentOS host I am using script make_chroot_jail.sh to put a user in a jail, not permitting it to see anything expect it's home at /home/jail/home/user1. I did it typing this: sudo ./make_chroot_jail.sh user1 after, when trying to connect to user1 first i was getting an error like: /bin/su: user guest does not exist i have fixed this by copying some missed libraries: sudo cp /lib64/libnss_compat.so.2 /lib64/libnss_files.so.2 /lib64/libnss_dns.so.2 /lib64/libxcrypt.so.2 /home/jail/lib64/ sudo cp -r /lib64/security/ /home/jail/lib64/ But now, when trying to connect to user1 typing su user1 and then typing it's password, i am getting this error: could not open session So the question is how to connect to user1 in this situation? P.S. Here are the permissions of some files, this might be helpful in order to provide a solution: -rwsr-xr-x 1 root root /home/jail/bin/su drwxr-xr-x 4 root root /home/jail/etc -rw-r--r-- 1 root root /home/jail/etc/pam.d/su -rw-r--r-- 1 root root /home/jail/etc/passwd -rw------- 1 root root /home/jail/etc/shadow UPDATE1 After some modifications i managed to connect to user1, but the session closes immediately! I guess this a PAM issue, however cant find a way to fix it. Here the log entry for close action from /val/log/secure: Oct 6 15:19:42 localhost su: pam_unix(su:session): session closed for user user1 What makes the session to exit immediately after launching?

• How can I run Gnome or KDE locally in Cygwin?

  - by John Peter Thompson Garcés

  Apparently it is possible to do this using cygwin ports, as can be seen in screenshots. I followed this how-to to get apt-cygports set up, and I used it to install gnome-session. This how-to supposedly gives the commands needed to run Gnome or KDE, but whenever I try to run Gnome, a blank X-window pops up and then quickly disappears.

• Users database empty after Samba3 to Samba4 migration on different servers

  - by ouzmoutous

  I have to migrate a Samba 3 to a new Samba 4 server. My problem is that the database on the samba 3 server seems a bit empty. The secrets.dtb file is only 20K whereas the “pbedit -L |wc -l”command give me 16970 lines. On my Samba3 /var/lib/samba is 1,5M After I had migrate the databse (following instructions on http://dev.tranquil.it/index.php/SAMBA_-_Migration_Samba3_Samba4), “pdbedit -L” command on the new server give me only : SAMBA4$, Administrator, dns-samba4, krbtgt and nobody. So I tried to create a VM with a Samba3. I added some users, done the same things I did for the migration and now I can see the users created on the VM. It’s like users on the Samba 3 server are in a sort of cache. I already migrate the /etc/{passwd,shadow,group} files and I can see users with the “getent passwd” command. Any ideas why my users are present when I use pdbedit but the database is so empty ?

• samba "username map" stopped to work after upgrade to 3.6

  - by Kris_R

  It was time to upgrade our group server (new HDs, problems with old installation of DRBD, etc..). Going as usually for CentOS i upgraded whole system from 6.3 to 6.4 The later one came with samba 3.6 as the old one was 3.5. I transferred most of users by copying /etc/password, /etc/shadow and samba accounts with pdbedit. Homes were on nfs-drive. The translation of unix accounts to samba accounts are located in /etc/samba/smbusers. Strangely enough on some windows clients there was problem to connect to samba-shares. In one case the only thing that worked was, instead of giving windows name, to use the unix account. In another one, it was possible to mount network drive and to open it in Windows Explorer, however other applications like "Total commander" at the attempt of opening this drive gave the message "Cannot connect to z:" (sometimes at this moment user/pass were requested). The smb.conf has following entries: [global] security = user passdb backend = tdbsam username map = /etc/samba/smbusers ... [Kris] comment = Kris's Private path = /SMB/Users/Kris writeable = yes read only = no browseable = yes users = krisr printable = no security mask = 0777 force security mode = 0 directory security mask = 0777 force directory security mode = 0 force create mode = 0775 force directory mode = 6775 The smbusers: # Unix_name = SMB_name1 SMB_name2 ... krisr = Kris Of course testparm runs without any errors. I was used from samba 3.5 to outputs of form Mapped user kris to krisr. Nothing like this happens now. Just message check_sam_security: Couldn't find user Kris in passdb. I read on web that some guys had problem with 3.6 and security = ADS, but these were not helpful for me. I'm seriously thinking about downgrading back to samba 3.5 but before this step I wanted to ask if somebody knows the solution of these problems.

  I installed git and gitosis as described here in this guide Here are the steps I took: Server: Gentoo Client: MAC OS X 1) git install emerge dev-util/git 2) gitosis install cd ~/src git clone git://eagain.net/gitosis.git cd gitosis python setup.py install 3) added git user adduser --system --shell /bin/sh --comment 'git version control' --no-user-group --home-dir /home/git git In /etc/shadow now: git:!:14665:::::: 4) On local computer (Mac OS X) (local login is ipx, server login is expert) ssh-keygen -t dsa got 2 files: ~/.ssh/id_dsa.pub ~/.ssh/id_dsa 5) Copied id_dsa.pub onto server ~/.ssh/id_dsa.pub Added content from file ~/.ssh/id_dsa.pub into file ~/.ssh/authorized_keys cp ~/.ssh/id_dsa.pub /tmp/id_dsa.pub sudo -H -u git gitosis-init < /tmp/id_rsa.pub sudo chmod 755 /home/git/repositories/gitosis-admin.git/hooks/post-update 6) Added 2 params to /etc/ssh/sshd_config RSAAuthentication yes PubkeyAuthentication yes Full sshd_config: Protocol 2 RSAAuthentication yes PubkeyAuthentication yes PasswordAuthentication no UsePAM yes PrintMotd no PrintLastLog no Subsystem sftp /usr/lib64/misc/sftp-server 7) Local settings in file ~/.ssh/config: Host myserver.com.ua User expert Port 22 IdentityFile ~/.ssh/id_dsa 8) Tested: ssh [email protected] Done! 9) Next step. There I have problem git clone [email protected]:gitosis-admin.git cd gitosis-admin SSH asked password for user git. Why ssh should allow me to login as user git? The git user doesn't have a password. The ssh key I created is for the user expert. How this should work? Do I have to add some params to sshd_config?

• PostgreSQL user authentication against PAM

  - by elmuerte

  I am trying to set up authentication via PAM for PostgreSQL 9.3. I already managed to get this working on an Ubuntu 12.04 server, but I am unable to get this working on a Centos-6 install. The relevant pg_hba.conf line: host all all 0.0.0.0/0 pam pamservice=postgresql93 The pam.d/postgressql93 is the default config shipped with the official postgresql 9.3 package: #%PAM-1.0 auth include password-auth account include password-auth When a user tries to authenticate the following is reported in secure log: hostname unix_chkpwd[31807]: check pass; user unknown hostname unix_chkpwd[31808]: check pass; user unknown hostname unix_chkpwd[31808]: password check failed for user (myuser) hostname postgres 10.1.0.1(61459) authentication: pam_unix(postgresql93:auth): authentication failure; logname= uid=26 euid=26 tty= ruser= rhost= user=myuser The relevant content of password-auth config is: auth required pam_env.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth required pam_deny.so account required pam_unix.so account sufficient pam_localuser.so account sufficient pam_succeed_if.so uid < 500 quiet account required pam_permit.so The problem is with the pam_unix.so. It is unable to validate the password, and unable to retrieve the user info (when I remove the auth entry of pam_unix.so). The Centos-6 install is only 5 days old, so it does not have a lot of baggage. The unix_chkpwd is suid and has execute rights for everybody, so it should be able to check the shadow file (which has no privileges at all?).

• Exchange backup verification shows no files

  - by Olaf

  [SBS2003SP2] If i read the exhange log it shows the backup contains no files just folders and the total size seems to be Ok. I i try to restore the folders are empty... But the 14 files that where backupped dissapeared in the verification log?! Other backups on the same medium turned out to be fine. Any idea what's wrong here?

• Samba4/Ubuntu Shares Incorrectly Available to All Users

  - by Dan

  I've got my Ubuntu server working with Samba4 and got it set up as the Primary domain controller on my network with AD and all that goodness. However, I'm trying to get my Samba configuration to work with the users and groups I've defined with the Active Directory tools from Windows. For instance, I've got a share X which I want users A and B (as part of the 'management' group, known as LLGrpManager in my setup) to see, but no body else. However, after making changes to the configuration, restarting Samba, I test by connecting to the share with my Mac over Samba as user 'C' which isn't part of the management group, and I can, incorrectly, see the X share. I've tried alsorts of combinations of specifying the group with no luck at all. I've got a feeling that my global config might be too lenient or something to do with file permissions but being a bit green, I'm without clue. My /etc/samba/smb.conf # Global parameters [global] server role = domain controller server string = Office Server workgroup = LLDOMAIN realm = lldomain.local netbios name = DUMBO passdb backend = samba4 logon path = \\%L\profiles\%U logon drive = L: log file = /var/log/samba/%m.log max log size = 50 security = ads domain logons = yes domain master = auto usershare allow guests = no valid users = %S [netlogon] path = /var/lib/samba/sysvol/lldomain.local/scripts read only = no guest ok = no [sysvol] path = /var/lib/samba/sysvol read only = No guest ok = no valid users = @LLDOMAIN\LLGrpManager [ShareX] path = /data comment = Entire Data Volume guest ok = no comment = Entire Data Volume guest ok = no valid users = @LLDOMAIN\LLGrpManager admin users = @LLDOMAIN\LLGrpManager browsable = no inherit acls = yes inherit permissions = yes ... My /etc/nsswitch.conf I've also instructed the system to use the nss winbind library when searching for users or groups by adding the stanza passwd and group in /etc/nsswitch.conf: passwd: compat winbind group: compat winbind shadow: compat Permissions on the folder in question drwxrwxrwt 8 root root 4.0K Oct 28 19:11 data

• FastGate A20 Line And Himem.sys Issue With Updating BIOS

  - by Boris_yo

  I have been persistent with a thought to perform my first BIOS update ever through MS-DOS but have been postponing this task until today. Despite people telling me any bootable ISO will do it either through CD-ROM or RAMDRIVE, I am still having problems. First is the problem with CD-ROM driver trying to make it work with 4 driver files (cd1.SYS, cd2.SYS, cd3.SYS, cd4.SYS) as well as starting RAMDISK proved to be failure: CD-ROM XMS Allocation Error RAMDISK XMS Allocaton Error (X: and R: drives not working) This A20 line seemed to be the obstacle which then after a couple of searches pointed me to this article on Microsoft website. It seems that FastGate is the culprit which takes over A20 line and conflicts with himem.sys which should be handling it causing the driver to be unable to allocate memory resources. Albeit article suggests 2 workarounds which is disabling FastGate option or adding switch, I read that the former workaround could cause problems which involves later tinkering BIOS, disabling shadow copy etc. while the latter workaround can just hang system as stated in the link above. I assume it just hangs the boot process from image file though. Summing up the above, I am cautious and think it is risky to follow both workarounds because disabling FastGate or trying adding switch by trying available switches from 1-14 or 16, could crash the BIOS update process by itself. I could do this without the need for himem.sys with bootable USB thumbdrive by making it to be seen as USB-HDD, but some time ago I read that it is never a good idea to update BIOS from hard drive so even thought it is simulation, who knows... Maybe it will deactivate hard drive in the middle of the BIOS update process or even USB thumbdrive per se? One forum discussion was about updating BIOS and somebody suggested to not load himem.sys for some reason, but now that I think of it, what if BIOS update needs upper memory?
