  • How to execute a shell script on startup?

    - by vijay.shad
    I have create a script to start a server(my first question). Now I want it to run on the system boot and start the defined server. What should I do to get this done? My findings tell me put this file in /etc/init.d location and it will execute when the system will boot. But I am not able to understand how the first argument on the startup will be start? Is this predefined somewhere to use start as $1? If I want to have a case startall that will start all the servers in the script, then what are the options I can manage. My Script is like this: #!/bin/bash case "$1" in start) start ;; stop) stop ;; restart) $0 stop $0 start ;; *) echo "usage: $0 (start|stop|restart)" ;; esac

  • Why doens't my Postgres user have permissions to add a Postgres database?

    - by orokusaki
    First, I ran: sudo su postgres createuser -U postgres foouser -P which worked fine, and I ran: createdb -U foouser -E utf8 -O foouser foodatabase -T template0 and got "permission denied: cannot create database" Firstly, should I even su as postgres to do operations like the first one (assuming my postgres data dir is owned by postgres), or is -U postgres from any user (assuming trust is used in pg_hba.conf) sufficient? Secondly, why am I running into this error? Is this because the user foouser is a non-superuser? Should I create foodatabase using the postgres user and simply -O foouser?

  • sendmail: how can I restrict access to clients that only have a valid certificate?

    - by lxg
    I want to reject all connections that don't present a valid SSL/TLS certificate. First of all is the access db file the correct one to be changing? I have already tried using the basic rule given in the documentation CertIssuer:/C=US/ST=California/O=endmail.org/OU=private/CN= Darth+20Mail+20+28Cert+29/[email protected] RELAY This will obviously need a rule afterward to filter and reject all that don't present the cert? Does anyone have any pointers as to what syntax I should use? wildcards? lxg

  • Bluetooth not seeing mouse (Fedora)

    - by Chris
    I have a Lenovo S10 'netbook' that I've installed Fedora 17 ("LXDE spin") on. So far pretty much everything works great, except, the on-board Bluetooth. lsusb shows the controller present (0a5c:2101 Broadcom Corp. Bluetooth Controller), hcitool dev shows hci0 present, but when I put my mouse ("Lenovo Bluetooth Laser Mouse," which works perfectly paired with a MacBook Pro, MacBook Air, Mac mini, and Lenovo SL500 (with a USB dongle; running Windows 7)) into pairing mode and run hcitool scan (reports "Scanning ..." and, without further information or error message, returns to the shell prompt), blueman-manager, or bluetooth-wizard (from the gnome-bluetooth package) and try to detect the mouse, I get nothing... Frustrating! Thanks anyone who can point me in the right direction!

  • Debian modem problem

    - by Raafat
    I'm a new Debian user, it looks like a very good choice 4 me, every thing is stable, free and easy to use. The problem is, I'm using my modem to establish a dial up connection to the internet (ppp) (a very old stupid way I'm forced to use for now), and using the KPPP application to do that, and nothing is working properly for me. it seems like it didn't recognize my modem or something. I already tried to make a few stuff, and now i know my modem is on /dev/tty0, so i made a link for that on /dev/modem, and query the modem using KPPP and it responded with something like: Ati : Ati0: Ati1: ... ... Ati7: with a textBox to fill up in front of each one of thees Atis, and now, when i press connect on kppp, it says modem ready, and that's it. BTW, my modem is MDC AC'97

  • VMXNET3 nic loses the ability to update ARP table after N hours

    - by Peter
    I have a fedora 18 VM that stops updating the arp table on eth1 after running for a number of hours to days. There are other VMs on the same hypervisor that can access all of the same networks without issue. A tcpdump of the offending NIC shows only ARP broadcasts but no responses. None of the other VMs on the vDS see the ARP broadcasts from the offending NIC. The only way I can currently solve the problem is to reboot the VM and then everything works for a while. I've tried changing the port on the vDS and even flipping the network configurations after I lose eth1's ARP table, but the ARP problem follows eth1 but I can access the machines that were originally on eth1. If I statically add the arp entries for machines on the same subnet I have no problems with connectivity. The Hypervisor is an HP BL49X series with flex-10 network modules. Has anyone seen anything like this before?

  • Configuring sudo to work without password

    - by aidan
    I'm trying to configure sudo to allow all users to restart apache without having to enter a password. Security concerns aside, why isn't this working? I added the line to /etc/sudoers: %admin ALL=NOPASSWD: /usr/sbin/apache2ctl $sudo -l User aidan may run the following commands on this host: (root) NOPASSWD: /usr/sbin/apache2ctl (ALL) ALL $sudo /usr/sbin/apache2ctl [sudo] password for aidan: Thanks for any help.

  • I've set an editor as default, how do I call it to open files in a shell?

    - by iight
    EDIT I thought of a better way to phrase the question. How can I find the alias that Ubuntu is using for a different text editor? Rather than using nano by typing nano file.txt, i'd like to be able to type sublime file.txt to open sublime editor. I don't know where to look to find these aliases. sudo update-alternatives --config editor does not show it as a choice, I only see the 'default' editors, like Nano and vim.tiny.

  • Why do I get "ignoring out-of-zone data" when restarting BIND

    - by 6bytes
    I've been using my own DNS server but then I moved to a third part DNS provider. Yesterday I wanted to go back to using my own DNS's and cancel this third party service. I've lowered TTL in current DNS conf, changed DNS info in GoDaddy for my domain and that's when problems started. My domain seems to be working only for some people but not for others so clearly something is wrong. When restarting bind service named restart everything seems to be OK but later in email from Logwatch I'm getting errors like this: mydomain.com:30: ignoring out-of-zone data (ns1.mydns.com): 3 Time(s) mydomain.info:16: ignoring out-of-zone data (ns1.mydns.com): 5 Time(s) Can anyone point me in the right direction?

  • Trouble setting up PATH for Java on Debian

    - by milkmansrevenge
    I am trying to get Oracle Java 7 update 3 working correctly on Debian 6. I have downloaded and set up the files in /usr/java/jre1.7.0_03. I have also set the following two lines at the end of /etc/bash.bashrc: export JAVA_HOME=/usr/java/jre1.7.0_03 export PATH=$PATH:$JAVA_HOME/bin Logging in as other users and root is fine, Java can be found: chris@mc:~$ java -version java version "1.7.0_03" Java(TM) SE Runtime Environment (build 1.7.0_03-b04) Java HotSpot(TM) 64-Bit Server VM (build 22.1-b02, mixed mode) However there are two cases where Java cannot be found as detailed below. Note that both of these worked fine when I have previously installed OpenJDK Java 6 via aptitude, but I need Oracle Java 7 for various reasons. Most importantly, I cannot run commands as another user via su, despite the PATH showing that Java should be present. The user was created with adduser chris root@mc:~# su chris -c "echo $PATH" /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/java/jre1.7.0_03/bin:/bin root@mc:~# su chris -c "java -version" bash: java: command not found root@mc:~# su chris -c "/usr/java/jre1.7.0_03/bin/java -version" java version "1.7.0_03" ... How can it be in the PATH but not be found? Update 05/04/2012: explained by Daniel, to do with it being a non-interactive shell so files such as /etc/profile and /etc/bash.bashrc are not executed. Doing a full swap to that user and running Java works: root@mc:~# su chris chris@mc:/root$ java -version java version "1.7.0_03" ... I run a script on start up which exhibits similar but slightly different problems. The script is located in /etc/init.d/start-mystuff.sh and calls a jar: #!/bin/bash # /etc/init.d/start-mystuff.sh java -jar /opt/Mars.jar I can confirm that the script runs on start up and the exit code is 127, which indicates command not found. Inserting a line to print/save the PATH shows that it is: /sbin:/usr/sbin:/bin:/usr/bin This second problem isn't as important because I can just point directly to the Java executable in the script, but I am still curious! I have tried setting the full PATH and JAVA_HOME explicitly in /etc/environment which didn't help. I have also tried setting them in /etc/profile which doesn't seem to help either. I have tried logging in and out again after setting PATH in the various locations (duh!). Anyway, long post for what will probably have a simple one line solution :( Any help with this would be greatly appreciated, I have spent far too long trying to fix it by myself. Motivation The first problem may seem obscure but in my system I have users that are not allowed SSH access yet I still want to run processes as them. I have a ton of scripts operating in this way and don't want to have to change them all.

  • Hylafax: Encounter "No font metric information" when try to send a fax

    - by Chau Chee Yang
    I am using Hylafax 6.0.5 on Fedora 13 x86_64. As there are no rpm package available for Fedora 13, I use the source tar ball to install hylafax myself. Everything seems fine during compile and install. I try to send a fax with sendfax and encounter error: # sendfax -n -d <fax-number> /etc/passwd /usr/local/sbin/textfmt: No font metric information found for "Courier-Bold". Usage: /usr/local/sbin/textfmt [-1] [-2] [-B] [-c] [-D] [-f fontname] [-F fontdir(s)] [-m N] [-o #] [-p #] [-r] [-U] [-Ml=#,r=#,t=#,b=#] [-V #] files... >out.ps Default options: -f Courier -1 -p 11bp -o 0 Error converting document; command was "/usr/local/sbin/textfmt -B -f Courier-Bold -Ml=0.4in -p 11 -s default >'/tmp//sndfaxp5GdJ9' <'/etc/passwd'" It seems like there is problem with font problem. I have ghostscript-fonts installed too. I can't find hyla.conf in path /etc/hylafax. There is no /etc/hylafax path in my file system. All configuration files seems located in /var/spool/hylafax/etc. Please advice. Thank you.

  • keyboard mappings are totally screwed after updating to kde4

    - by zeonglow
    I recently upgraded from KDE 3.5 to KDE 4, and I have been having weird issues with my keyboard. In one of the virtual consoles e.g. when I press ctrl + alt 1 , I can type perfectly, but in KDE, several of the number keys don't work, the left and right arrows don't work either. When I press the right arrow key in xev I get this: KeyRelease event, serial 34, synthetic NO, window 0x3600001, root 0x6f, subw 0x0, time 903459, (111,55), root:(115,836), state 0x10, keycode 114 (keysym 0x1008ff11, XF86AudioLowerVolume), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False When I press the '3' key it toggles my Bookmarks toolbar in Firefox, in xev I get this: KeyPress event, serial 34, synthetic NO, window 0x3600001, root 0x6f, subw 0x0, time 999968, (94,115), root:(98,896), state 0x10, keycode 12 (keysym 0x1008ff30, XF86Favorites), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 34, synthetic NO, window 0x3600001, root 0x6f, subw 0x0, time 1000032, (94,115), root:(98,896), state 0x10, keycode 12 (keysym 0x1008ff30, XF86Favorites), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False As this is deeper down, changing the type of keyboard in the KDE meun's has no effect. I'm slowly beginning to wade through the mountains of documentation about the X keyboard model, but there has to be a better way. Does anyone no what it is? Edit: 1234567890 ! after deleting the entire .kde folder. but only until I change the Keyboard settings from the "system settings" applet, then its hosed full time. Regardless of what I set the settings too. (restore to default settings doesn't) 2nd Edit: I'm using Gentoo AMD64, I was upgrading from KDE 3.5 KDE 4.2. I think I had manual settings before, although I didn't change anything. I was originally running KDE without HAL until that stop working a year or so ago. The only customisation I made was to set the multimedia keys to control Amarok. 3rd Edit $ grep xkb /var/log/Xorg.0.log (**) Option "xkb_rules" "evdev" (**) Option "xkb_model" "evdev" (**) Option "xkb_layout" "us" (**) Option "xkb_rules" "evdev" (**) Option "xkb_model" "evdev" (**) Option "xkb_layout" "us" Xorg.0.log has this to say: (WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.

  • RHEL5 + Awesome WM - How do i fix mod4 inversion (acts like mod4 is always pressed)

    - by sgr
    I built and installed Awesome WM on RHEL5. I have problem with mod4 acting like its always pressed. ie every time i hit "Enter" it acts like Mod4+Enter was hit. I have to hold down mod4 key (I remapped it to Caps_Lock) to actually send through just a Enter. How do i fix this? PS: If i change the WM this problem doesnt exist. yes. I do. It is mostly tab configs though. I didnt change key combos. Also, the version of awesomeWM i compiled is 3.1.1 (had trouble getting deps for the latest AwesomeWM on Rhel5)

  • Top/left edges of screen, in Virtualbox, act like bottom/right edges

    - by Ken
    I have Virtualbox running on Windows Vista, and Debian running inside Virtualbox. Everything's running great, for the most part. Everything looks correct. But when I'm in full-screen mode, the top edge seems to act (to the mouse) like it's the bottom edge, and the left edge seems to act like the right edge. For example, if I click in the middle of the desktop and drag left, as if to select some icons, when I hit the very leftmost pixel of the screen, the selection (but not the mouse pointer) jumps to the far right edge of the screen). For the left edge, it's not such a big deal, but not having the top edge is kind of annoying: it means I can't select things from the menu in my top panel by slamming the mouse against the top of the screen. Anyone seen this before? Is there some way to make this work? Thanks!

  • Ganglia and how it communicates

    - by MikeKulls
    I'm a little confused about how Ganglia sends information around and have found conflicting information on the web. I would have thought that the gmond process would either send info to gmetad at a regular interval or gmetad would request info from the various instances of gmond. At least one online article states this is how it works but from what I understand this is incorrect. It appears that you configure all gmond processes to send their info to a central gmond process and gmetad will request info from that central gmond. Is that correct? In my case I have 6 servers sending their information to 1 central server. If I set gmetad to get it's information from the central server then I get information from all 6 servers, all good.. Their weird thing is that if I point gmetad to one of the 6 servers then I still get info from all 6 servers. How is it that server 1 in my cluster if getting stats from all the other servers?

  • bash : "set -e" and check if a user exists make script exit

    - by Dahmad Boutfounast
    i am writing a script to install a program with bash, i want to exit on error so i added "set -e" in the beginning of my script. the problem is that i have to check if a user exists inside of my script, to do this i am using "grep "^${USER}:" /etc/passwd", if the user exists, the script runs normally, but if the user doesn't exist, this command exists, and i don't want to exit on this case (i have to create the user and continue my installation). so what's the solution to make my script continue running ?? i tried to redirect the output of "grep" to a variable, but i still have the same problem :( thanks.

  • Using WinSCP with SSH server and 2 machine hops

    - by Mike
    I'm on a windows machine using putty to ssh into my schools server. From there I need to "slogin -XY machine1" and then "slogin -XY machine2" . Ideally, I'd like to use WinSCP to connect and transfer files. I know I can do this by using two copies of PuTTY , one to ssh into the server and create a proxy, and the second PuTTY to connect to the proxy and login to machine1 and create a second proxy. I can then use winSCP to connect to the proxy server and login to machine2... Is there a simpler way of doing this?

  • Dovecot, Postfix, Postfixadmin - can't send/receive mail

    I am setting up a mail server: Dovecot and Postfix with MySQL support and Postfixadmin.

  • Make cloudera-vm work on Oracle VM VirtualBox

    - by ????? ????????
    I downloaded this and the instructions say: Important: You must enable the I/O APIC in order to use 64-bit mode. (See http://www.virtualbox.org/manual/ch03.html.) On newer versions of VirtualBox, it may default to using SATA as the disk interface. This can cause a kernel panic in the VM. Switching to the IDE driver solves this problem. I am running this on Red Hat 64-bit mode (I've also tried on Ubuntu 64-bit with the same result). I pointed to the cloudera-vm image as a startup disk for the VM. I am getting this message: Failed to open a session for the virtual machine ClouderaDevelopment. VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED). Result Code: E_FAIL (0x80004005) Component: Console Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} Does anyone know what I am doing wrong?

  • nginx - 403 Forbidden

    - by michell90
    I've trouble to get aliases working correctly on nginx. When i try to access the aliases, /pma and /mba (see secure.example.com.conf), i get a 403 Forbidden but the base url works correctly. I read a lot of posts but nothing helped, so here i am. Nginx and php-fpm are running as www-data:www-data and the permissions for the directories are set to: drwxrwsr-x+ 5 www-data www-data 4.0K Dec 5 22:48 ./ drwxr-xr-x. 3 root root 4.0K Dec 4 22:50 ../ drwxrwsr-x+ 2 www-data www-data 4.0K Dec 5 13:10 mda.example.com/ drwxrwsr-x+ 11 www-data www-data 4.0K Dec 5 10:34 pma.example.com/ drwxrwsr-x+ 3 www-data www-data 4.0K Dec 5 11:49 www.example.com/ lrwxrwxrwx. 1 www-data www-data 18 Dec 5 09:56 secure.example.com -> www.example.com/ Im sorry for the bulk, but i thought better too much than too little.

  • Monitoring Maximum Process Network Activity

    - by user125973
    We have a collocated server on which we run some OpenVZ hosts. Recently, we have had to pay a lot extra we keep exceeding our bandwidth quota. Our quota is 5 Mb/s but we have spike to almost 50. I looked at the graphs and there are some spikes happening at some intervals. I want to know which process is causing this so I need a tool that monitors the processes and gives me the one with the maximum instant traffic (It doesn't matter how much traffic we have as long as we don't exceed the 5Mb/s quota). Does anyone have a recommendation for this? My hosts are CentOS 5 with OpenVZ so I can see all the containter processes from the host, if that helps in any way.

  • Editing sudoers file to restrict a user's commands

    - by devin
    Is it possible to edit the sudoers file so a user can use sudo for any command except for a specified one? I reverse is true, I believe, that the sudoers file can be setup so that a user can only execute a given list of commands. EDIT: the commands I really want to take away are halt and reboot... this makes me think there are special system calls for halt and reboot. Can you take system calls away from a user? If not, is it because the unix permission system abstracts over system calls neglecting this?
