• Understanding the Linux Root

  - by Zac

  I've been using Linux (Ubuntu) for about 2 weeks now and am still struggling with some basic concept surrounding the root user: (1) Some terminal operations (such as making subdirectories inside a FHS directory such as /opt) require me to prefix the command with sudo - why? I guess what I'm choking on is: if I'm already logged in as a valid system user, why do I have to be a superuser/root in order to modify things that the sysadmin has already deemed me worthy of accessing? (2) Is there a GUI (Gnome, KDE) equivalent to sudo? Is there a way to assume a superuser role through a graphical context, rather than from inside a new shell? (3) I can't access the /root directory logged in as myself... but I installed the system to begin with and was never asked to create a root account! How do I log in as root and gain access to /root?!? Thanks for all feedback & input!

• Recursively move files in sub-dirs to new sub-dirs of same name

  - by Gabriel

  I have a batch of files all ending with the same string, ie: *_ext.dat located in several sub-dirs along with several other files, in a given main dir. This is the structure: /main_dir/subdir1/file11_ext.dat /main_dir/subdir1/file12_ext.dat /main_dir/subdir1/file13_ext.dat /main_dir/subdir1/file14_other.dat /main_dir/subdir1/file15_other.dat /main_dir/subdir2/file21_ext.dat /main_dir/subdir2/file22_ext.dat /main_dir/subdir2/file23_ext.dat /main_dir/subdir2/file24_other.dat /main_dir/subdir2/file25_other.dat /main_dir/subdir3/file31_ext.dat /main_dir/subdir3/file32_ext.dat /main_dir/subdir3/file33_ext.dat /main_dir/subdir3/file34_other.dat /main_dir/subdir3/file35_other.dat I need to recursively move only the files ending in *_ext.dat into a new main dir, new_dir, respecting the sub-dir structure so the files will end up in an equivalent dir structure like this: /new_dir/subdir1/file11_ext.dat /new_dir/subdir1/file12_ext.dat /new_dir/subdir1/file13_ext.dat /new_dir/subdir2/file21_ext.dat /new_dir/subdir2/file22_ext.dat /new_dir/subdir2/file23_ext.dat /new_dir/subdir3/file31_ext.dat /new_dir/subdir3/file32_ext.dat /new_dir/subdir3/file33_ext.dat Because of this the command should also create those sub-dirs with their corresponding names. I know that with a line like this one: find . -name "*_ext.dat" -print0 | xargs -0 rm -rf I can delete all those files, but I don't know how to modify it to do what I need (or if it is even possible).

• Netboot Debian (wheezy) from NFS v4

  - by bara

  Is it possible to boot Debian Wheezy from NFS v4? Bootwing with NFS v3 works just fine. NFS v4 not. This is in my /etc/exports: /nfs 192.168.100.0/24(ro,sync,insecure,no_root_squash,no_subtree_check,fsid=0) /nfs/root 192.168.100.0/24(ro,nohide,sync,insecure,no_root_squash,no_subtree_check) /nfs/root/www contains the root of the webserver. The commandline is: rootfstype=nfs4 root=/dev/nfs4 nfsroot=192.168.100.1:/root/www fails with mount call failed - server replied: Permission denied. Mounting from the busybox in the initrd fails: mount -t nfs4 192.168.100.1:/nfs/root/www /root mounting .. failed: Invalid argument Do I need to modify the initrd?

• Joomla 1.5 Media Manager sets incorrect file permissions when uploading

  - by Scott Mayfield

  Howdy all, I have a Joomla 1.5 installation running on Windows Server 2008, installed via the Web Platform Installer. When uploading images with the media manager (native uploader, not the flash bulk uploader), the files arrive on the server correctly, but are given incorrect permissions. Specifically, the IIS_IUSRS group is not given access to the file. I might be incorrect about what group/user is SUPPOSED to get access to the files, but so far, I've found that unless I give IIS_IUSRS access to the uploaded files, they won't appear on the site or in the media manager (appear as broken images). Once I give IIS_IUSRS permission to the files, they work fine. So far, all the research I've done has led me to linux specific fixes that involve either changing the umask on the server, or directly modifying the Joomla codebase to add an appropriate chmod command to the upload process, but I really don't want to modify Joomla directly. I have to believe there's a setting here somewhere that will do the job, either on the Joomla or Windows side of the equation. Any thoughts? Scott

• Open-source training class/room/instructor resource management software?

  - by Kyle Eli

  We're looking to replace an internal system used for managing training classes with something a bit more robust. Needs to be open-source or have a license level that grants access to source, and needs to be ASP.net (C# preferred, but could live with VB.net) Ultimately, we'll need to be able to assign facilities and instructors, manage attendees, send notifications, and build calendar views. We'll also be integrating with our website to allow on-line sign-up and other things for attendees to manage on their own. We do expect to implement quite a bit of it in-house, but we'd like as broad of a base to start from as we can get. Still, just a really good web-based meeting-room reservation system might make a good enough starting point. In list form: Meeting/training resource management softwareASP.net (C# or VB.net)Source availableWe're expecting to have to modify the software to meet all of our requirements

• How to know the maximum capacity of memory/RAM of a server? [closed]

  - by Nam G. VU

  I have a Dell PowerEdge T410 and have installed 16Gb RAM for it. I don't know if I can extend it to 32Gb, 64Gb, ... RAM on this server. As the description, it seems I have no such choice. So my question is, how to know exactly the maximum capacity of memory/RAM of a server? I need this information so as to verify the number by myself. ps. My server is not exactly the same as the description on Dell website - I indeed modify the configuration to meet my budget. Currently my server is my purchased server configuration

• How to boot RHEL with no bash?

  - by nmelmun

  How can I boot a RHEL VM if I deleted /bin/bash? When trying to boot, I now get the following error: "INIT: Cannot execute "/etc/rc/d/rc.sysinit" The next thing I tried was to modify the kernel boot parameters by adding init=/bin/ksh at the end of the line, which gave me a functional shell. After this, in order to get write permissions, I remounted the root partition with: mount -o remount,rw / Then I tried to boot using ksh as the shell by tricking the system into thinking it's bash: ln -s /bin/ksh /bin/bash Then restarted the system normally. Unfortunately this didnt work since ksh is not compatible and /etc/rc.d/rc.sysinit uses several bash-specific tricks. Does anyone else have a suggestion on how I could get the system to boot normally without reinstalling bash?

• Automating and deploying new linux servers

  - by luckytaxi

  I'm in the process of developing a method to automate new virtual machines into my environment. 90% of our machines are virtual but the process is similar for both physical and vmware based images. What I do now is I use cobbler to install the base OS. The kickstart script has post hooks to modify the yum repo and installs puppet and func. Once the servers are running, I manually add them into nagios and sign the certificate via the puppetmaster. I've since migrated most of the resources to use mysql as the backend. I wanted to see what others are doing and my goal for 2011 is to have puppet inventory the hardware into mysql, and somehow i'll script a python script to have nagios grab the info and automatically add it for monitoring purposes. It's kind of tedious to have to add each new server into nagios, puppet's dashboard, munin, etc...

• Is there a "rigorous" method for choosing a database?

  - by Andrew Martin

  I'm not experienced with NoSQL, but one person on my team is calling for its use. I believe our data and its usage isn't optimal for a NoSQL implementation. However, my understanding is based off reading various threads on various websties. I'd like to get some stronger evidence as to who's correct. My question is therefore, "Is there a technique for estimating the performance and requirements of a certain database, that I could use to confirm or modify my intuitions?". Is there, for example, a good book for calculating the performance of equivalent MongoDB/MySQL schema? Is the only really reliable option to build the whole thing and take metrics?

• Can I password protect a Publisher file?

  - by tombull89

  I was asked ealier this week if it was possible to password protect a Microsoft Office 2007 Publisher document. I was under the impression that it would be like protecting a Word document, by going to Office Save As Word Document Tools General Options and creating a password to modify, like shown below. This also works for Excel documents. However, in Publisher 2007 the option is not there. The only option under "Tools" is "Map network drive". We overcame the issue as saving as a PDF and distributing that, but is there a way to do what we want?

• Hostname problems in CentOS 5.5

  - by spoon16

  I just set up a CentOS 5.5 machine on my local network and attempted to modify the hostname by editing /etc/sysconfig/network file. When I'm logged in locally the change to the hostname is reflected and seems to be working fine. When I open a SSH session via PuTTY from Windows this is what I see at the prompt: [root@? ~]# cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=mini.local [root@? ~]# sysctl kernel.hostname kernel.hostname = ? [root@? ~]# hostname ? [root@? ~]# hostname -f hostname: Unknown server error A couple of other symptoms that may be helpful in troubleshooting this problem. I can ping the CentOS box from my Windows machine via IP but not hostname. Also, my Netgear router does not display the hostname when I view the "Connected Devices", I do see the mac address and the proper IP listed though. How can I make it so that the hostname is properly propagated throughout my network?

• Problem with testsaslauthd and kerberos5 ("saslauthd internal error")

  - by danorton

  The error message “saslauthd internal error” seems like a catch-all for saslauthd, so I’m not sure if it’s a red herring, but here’s the brief description of my problem: This Kerberos command works fine: $ echo getprivs | kadmin -p username -w password Authenticating as principal username with password. kadmin: getprivs current privileges: GET ADD MODIFY DELETE But this SASL test command fails: $ testsaslauthd -u username -p password 0: NO "authentication failed" saslauthd works fine with "-a sasldb", but the above is with "-a kerberos5" This is the most detail I seem to be able to get from saslauthd: saslauthd[]: auth_krb5: krb5_get_init_creds_password: -1765328353 saslauthd[]: do_auth : auth failure: [user=username] [service=imap] [realm=] [mech=kerberos5] [reason=saslauthd internal error] Kerberos seems happy: krb5kdc[](info): AS_REQ (4 etypes {18 17 16 23}) 127.0.0.1: ISSUE: authtime 1298779891, etypes {rep=18 tkt=18 ses=18}, username at REALM for krbtgt/DOMAIN at REALM I’m running Ubuntu 10.04 (lucid) with the latest updates, namely: Kerberos 5 release 1.8.1 saslauthd 2.1.23 Thanks for any clues.

• How to config DNS onto TCP from UDP

  - by Dante Jiang

  Google DNS (8.8.8.8 and 8.8.4.4) are blocked (or polluted) by all ISPs available to me (and DNS by ISPs just return wrong answers for some sensitive sites!!), and it is said that if we change DNS from UDP onto TCP, the problem can be temporarily solved. My question is: how to config that on Windows 7? The solution provided by the original post: Windows 7 Ultimate DnsApi.dll v6.1.7601.17570 .text:6DC08FC8 8B 46 10 mov eax, [esi+10h] .text:6DC08FCB 89 45 F4 mov [ebp+var_C], eax var_C - 2 85A0: 90 90 90 90 90 -> 33 C0 40 EB 25 85C8: 8B 46 10 -> EB D6 40 I have not figure out how the original solution works so far. It needs to modify the .dll file, and the post provides a .dll after modification. However, I wish there was a solution without this kind of hacking.

• Running game server and webserver on EC2

  - by mazzzzz

  Hey guys, I have a webhost, and an EC2 server (to run a game server on). The problem is that I want to access/modify the EC2's files with php admin programs. I looked into a lot of options to just have the webhost communicate with the EC2 server (ssh, etc), but none of them panned out. My question is if I were to install a lightweight webserver (think lighttpd) on my EC2 server, how badly would it hurt the game server's performance? I was leaning away from this solution, even though the webserver (on the EC2 server) wouldn't get many hits (less than a 100 a day). Thanks for your thoughts, Max

• Syslog permissions

  - by Niels Kristian

  I'm using the $InputFile facility in rsyslog to monitor various log files scattered around my ubuntu 12.04 server. E.g. nginx, unicorn, rails, postgres, cron etc. Now my problem is, that some of these log files are created with -rw-r----- right, so rsyslog doesn't have read rights. Since I install most of the programs using apt-get, and therefore didn't change anything from default. So, in other words, I would like not to modify every singe log file / daemon to have the right permissions, if I instead could give syslog read access to all of them at once. But the question is - can I do that, and is it the "right thing to do"?

• You may be attempting to write into another users folder which is not supported...

  - by Triynko

  Why do I get this message when trying to compile a file in Flash MX 2004? "If you are logged in with a limited user account, then you may be attempting to write into another users folder which is not supported." The folder and files are owned by the Administrators group; however, the user trying to modify the files is a member of a group which is inheriting permissions to have full control over the files, except take ownership and change permissions. Why would a user, whose effective permissions include virtually everything, be unable to write to a file... and end up getting an error message like the one described?

• Is there a way to have customised text instead of subject in Thunderbird's inbox list?

  - by peterp

  I am getting a lot of informational emails like "You've got a new message from ..." or "Notification of Donation Received", which often do not contain any information in the subject so that I have to open the email to see who sent the message or who donated which amount. I'd love to be able to make TB parse incoming emails and then display something interesting instead of the original subject, e.g. by defining a regular expression pattern. I know how to write regular expressions, but I do not know whether there is a way or an addon to modify the displayed text in the messages view. EDIT for clarification: I would like donation notifications from Paypal not to be displayed as original Notification of Donation Received but rather Paypal: John Doe has donated 50$

• Using Supervisord, how can I start a brand new worker via supervisorctl without restarting other workers?

  - by cballou

  Let's say I have a number of existing workers running in supervisord. I want to add a new worker to the group as well as start the new worker. I perform the following steps: I modify the file /etc/supervisor/supervisord.conf and add the new worker config Back on the command line, I enter sudo supervisorctl I run reread to read the new configuration file settings. Attempting to run start workers:exampleWorkerName gives the error workers:"exampleWorkerName": ERROR (no such process) So, my question is, how can I start this new worker process without affecting my other existing workers? I'd rather not perform a supervisorctl reload or /etc/init.d/supervisord restart command.

• Storing large amounts of small files into bigger files on Windows

  - by asmo

  Let's say I have 50 GiB of files that weights around 500 KiB each. My guess is that having, for example, 5 large files of 10 GiB each with the same content archived in them would be better for hard drive performance. Am I correct? Will there be a noticeable gain on an NTFS filesystem? ===================================================================== Finally, which tool could I use to group the files together while retaining the ability to modify the content of the archive with zero or minor performance loss? For example, I like TrueCrypt archiving because after mounting an archive file, it creates a drive which I can use seamlessly as if it was a normal drive. The only thing with TrueCrypt is that I don't need encryption/compression, only archiving.

• Batch Convert .mkv to .mp4

  - by IamHere

  I want to batch convert all .mkv files in a folder into .mp4 with VLC. It should use the original video-/audio stream and if possible the .ass subtitle of the .mkv. It's not really a conversion, it's more like changing the container – my player can't read the MKV videos. If I do this conversion by hand (manually) it works, but I have a lot of MKV files to convert, so it would take a lot of time. I have searched the internet for a batch file to do this and I found a few. I tried to modify them to my wish, but all attempts I tried just created a .mp4 file that doesn't contain the audio stream and the video stream also cannot be rendered by all my media players on the PC. So could someone tell me how the batch has to look like, so it works with the original video and audio stream (and maybe .ass subtitles)?

• Automatically generated /etc/hosts is wrong

  - by Niels Basjes

  I've created a kickstart script to install CentOS 5.5 (32bit) in a fully automated way. The DNS/DHCP setup correctly gives the system the right hostname in both the forward and reverse lookups. dig node4.mydomain.com. +short 10.10.10.64 dig -x 10.10.10.64 +short node4.mydomain.com. In the state the installed system is right after the installation completed is as follows: cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes GATEWAY=10.10.10.1 HOSTNAME=node4.mydomain.com echo ${HOSTNAME} node4.mydomain.com cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 10.10.10.64 node4 My problem is that this automatically generated hosts file is slightly different from the way I want it (or better: the way Hadoop wants it). The last line should look like this: 10.10.10.64 node4.mydomain.com node4 What do I modify where to fix this? Thanks.

• Set up linux box for hosting a-z

  - by microchasm

  I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP/MySQL: To upgrade PHP and MySQL to the latest versions, I had to look to another repo outside CentOS. IUS looks great and I'm happy I found it! Add IUS repository to our package manager cd /tmp wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm rpm -Uvh epel-release-1-1.ius.el5.noarch.rpm wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-4.ius.el5.noarch.rpm rpm -Uvh ius-release-1-4.ius.el5.noarch.rpm yum list | grep -w \.ius\. # list all the packages in the IUS repository; use this to find PHP/MySQL version and libraries you want to install Remove old version of PHP and install newer version from IUS rpm -qa | grep php # to list all of the installed php packages we want to remove yum shell # open an interactive yum shell remove php-common php-mysql php-cli #remove installed PHP components install php53 php53-mysql php53-cli php53-common #add packages you want transaction solve #important!! checks for dependencies transaction run #important!! does the actual installation of packages.
