  • Backup all plesk MySQL Databases to individual files

    - by Michael
    Hy, Because I'm new to shell scripting I need a hand. I currently backup all mydatabases to a single file, thing that makes the restore preaty hard. The second problem that my MySQL password dosen't work because of a Plesk bug and i get the password from "/etc/psa/.psa.shadow". Here is the code that I use to backup all my databases to a single file. mysqldump -uadmin -p`cat /etc/psa/.psa.shadow` --all-databases | bzip2 -c > /root/21.10.2013.sql.bz2 I found some scripts on the web that backup each database to individual files but I don't know how to make them work for my situation. Here is a example script: for db in $(mysql -e 'show databases' -s --skip-column-names); do mysqldump $db | gzip > "/backups/mysqldump-$(hostname)-$db-$(date +%Y-%m-%d-%H.%M.%S).gz"; done Can someone help me make the script above work for my situation? Requirements: Backup each database to individual file using plesk password location.

  • How to setup IP alias on bridged interface in Ubuntu

    - by Anonymouslemming
    How do I setup an IP alias on a bridge (br0) device on Ubuntu ? If I wait for br0 to come up and then do /sbin/ifconfig br0:0 192.168.10.1 netmask 255.255.255.0 then it works fine. If however I add the following to my /etc/network/interfaces file, it does not work and the network fails to start: auto br0:0 iface br0:0 inet static address 192.168.10.1 netmask 255.255.255.0 At the moment, I have a script in /etc/network/if-up.d/bridge_alias that does this as follows: #!/bin/bash if [ "${LOGICAL}" == "br0" ] && [ "${PHASE}" = "post-up" ]; then echo -n "Starting br0:0 ... " /sbin/ifconfig br0:0 192.168.10.2 netmask 255.255.255.0 echo "Done!" fi What is the right way of doing this though, just using the OS network config files ?

    Is there a command that can be run to verify that a users cron job has run successfully? Platform is Ubuntu 8.04 LTS. I have scripts in /home/useraccount/bin/ running crontab -l while logged in as user results in: # m h dom mon dow command @hourly /home/useraccount/bin/script_1 @hourly /home/locateruser/bin/script_2 I realize scripts could send email or write to a log with a timestamp, but wondering if there is just a way to verify it ran from the command line.

  • What cause high CPU usage on the server during file upload

    - by bosiang
    When I try to upload a huge file size (approx 2GB), the server cpu usage goes really high. What should I do to fix this? I just use standard html form and php, for file upload. I'm sorry if I post on the wrong forum. Please point me to the right direction here is the result of "top" command during uploading 4 files (18mb, 38mb, 60mb, 33mb) 1904 apache 20 0 33504 5740 1952 R 28.3 0.2 0:02.19 httpd 1905 apache 20 0 33504 5740 1952 R 28.3 0.2 0:01.99 httpd 1903 apache 20 0 33232 6968 3060 R 28.0 0.2 0:01.98 httpd 1910 apache 20 0 33240 6020 2248 S 11.5 0.2 0:02.85 httpd 2133 root 20 0 2656 1124 896 R 1.6 0.0 0:00.71 top 1 root 20 0 2864 1404 1188 S 0.0 0.0 0:03.99 init the code for chunking, although eventhough I don't use this code (just simple file upload), it still cause that high cpu usage function sendRequest() { //clean the screen //bars.innerHTML = ''; var file = document.getElementById('fileToUpload'); for(var i = 0; i < file.files.length; i++) { var blob = file.files[i]; var originalFileName = blob.name; var filePart = 0 const BYTES_PER_CHUNK = 100 * 1024 * 1024; // 10MB chunk sizes. var realFileSize = blob.size; var start = 0; var end = BYTES_PER_CHUNK; totalChunks = Math.ceil(realFileSize / BYTES_PER_CHUNK); alert(realFileSize); while( start < realFileSize ) { if (blob.webkitSlice) { //for Google Chrome var chunk = blob.webkitSlice(start, end); } else if (blob.mozSlice) { //for Mozilla Firefox var chunk = blob.mozSlice(start, end); } uploadFile(chunk, originalFileName, filePart, totalChunks, i); filePart++; start = end; end = start + BYTES_PER_CHUNK; } } }

  • How do I set default group ownership for files in a directory?

    - by tnichols
    I am running a cakephp webapp on Linode LAMP. I am finding that my temp files are created with root:root ownership. But the webapp is running with Apache's permissions (www-data). This causes warnings any time there is a new file created because it is not writable for user www-data. How do I change the default ownership to www-data on any new files created in the temp folder? Thanks for your help!

  • sudoer scheme to allow useful access to another web developer yet retain future control of a virtual

    - by Tchalvak
    Background: Virtual Private Server I have a virtual private server that I'm looking to host multiple websites on, and provide access to another web developer. I don't care about putting too many constraints on him, though I wouldn't mind isolating the site that he'll be developing from other sites on the server that I will develop. The problem: retain control Mainly what I want is to make sure that I retain control over the server in the future. I want to reserve the ability to create/promote/demote and other administrative functions that don't deal with web software. If I make him an admin, he can sudo su - and become root and remove root control from me, for example. I need him not to be able to: take away other admin permissions change the root password have control over other security/administrative functions I would like him to still be able to: install software (through apt-get) restart apache access mysql configure mysql/apache reboot edit web development configuration type files in /etc/ Other Standard Setups would be happily considered I've never really set up a good sudoers file, so simple example setups would be very useful, even if they're only somewhat similar to the settings that I'm hoping for above. Edit: I have not yet finalized permissions, so standard, useful sudo setups are certainly an option, the lists above are more what I'm hoping I can do, I don't know that that setup can be done. I'm sure that people have solved this type of problem before somehow, though, and I'd like to go with something somewhat tested as opposed to something I've homegrown.

  • LVS / IPVS difference in ActiveConn since upgrading

    - by Hans
    I've recently migrated from an old version of LVS / ldirectord (Ultra Monkey) to a new Debian install with ldirectord. Now the amount of Active Connections is usually higher than the amount of Inactive Connections, it used to be the other way around. Basically on the old load balancer the connections looked something like: -> RemoteAddress:Port Forward Weight ActiveConn InActConn -> 10.84.32.21:0 Masq 1 12 252 -> 10.84.32.22:0 Masq 1 18 368 However since migrating it to the new load balancer it looks more like: -> RemoteAddress:Port Forward Weight ActiveConn InActConn -> 10.84.32.21:0 Masq 1 313 141 -> 10.84.32.22:0 Masq 1 276 183 Old load balancer: Debian 3.1 ipvsadm 1.24 ldirectord 1.2.3 New load balancer: Debian 6.0.5 ipvsadm 1.25 ldirectord 1.0.3 (I guess the versioning system changed) Is it because the old load balancer was running a kernel from 2005, and ldirectord from 2004, and things have simply changed in the past 7 - 8 years? Did I miss some sysctl settings that I should be enforcing for it to behave in the same way? Everything appears to be working fine but can anyone see an issue with this behaviour? Thanks in advance! Additional info: I'm using LVS in masquerading mode, the real servers have the load balancer as their gateway. The real servers are running Apache, which hasn't changed during the upgrade. The boxes themselves show roughly the same amount of Inactive Connections shown in ipvsadm.

  • monitor power and lock screen (Ubuntu Lucid)

    - by xsznix
    Hi, I'm trying to get my screen to turn off whenever I lock my screen. I know that in Power Management, there's an option to turn off the screen after a set amount of time, and I know about xset dpms force off, but the former doesn't allow me to turn off the screen from the logout menu, and the latter only turns the screen off for a short amount of time (1 minute or so. The screen just turns back on by itself). Is there a script I can modify to change what happens when "Lock screen" from the logout menu is selected, or is there a script I can add to the panel to lock the screen and then turn the monitor off (and turning it back on when I shake the mouse or something)? Thanks.

  • Is there an email client optimized for screen readers and accessiblity?

    - by Adolfo Fitoria
    Hi. I'm currently working on a project to help visually impaired people. We're planning to use Orca screen reader for gnome. Everything is doing great but there is a problem with email web clients the most popular ones(gmail, yahoo, hotmail) are not optimized for screen readers. Is there some kind of simple email client optimized for this? Need to be very simple and straight foward and support multiple users too.

  • What's a good tool for collecting statistics on filesystem usage?

    - by Kamil Kisiel
    We have a number of filesystems for our computational cluster, with a lot of users that store a lot of really large files. We'd like to monitor the filesystem and help optimize their usage of it, as well as plan for expansion. In order to this, we need some way to monitor how these filesystems are used. Essentially I'd like to know all sorts of statistics about the files: Age Frequency of access Last accessed times Types Sizes Ideally this information would be available in aggregate form for any directory so that we could monitor it based on project or user. Short of writing something up myself in Python, I haven't been able to find any tools capable of performing these duties. Any recommendations?

  • disable specific PCI device at boot

    - by Rhymoid
    I've just reinstalled Debian on my Sony VAIO laptop, and my dmesg and virtual consoles all get spammed with the same messages over and over again. [ 59.662381] hub 1-1:1.0: unable to enumerate USB device on port 2 [ 59.901732] usb 1-1.2: new high-speed USB device number 91 using ehci_hcd [ 59.917940] hub 1-1:1.0: unable to enumerate USB device on port 2 [ 60.157256] usb 1-1.2: new high-speed USB device number 92 using ehci_hcd I believe these messages are coming from an internally connected USB device, most likely the webcam (since that's the only thing that doesn't work). The only way I can seem to have it shut up (without killing my actually useful USB ports) is to disable one of the USB host controllers: # echo "0000:00:1a.0" > /sys/bus/pci/drivers/ehci_hcd/unbind This also takes down my Bluetooth interface, but I'm fine with that. I would like this setting to persist, so that I can painlessly use my virtual console again in case I need it. I want my operating system (Debian amd64) to never wake it up, but I don't know how to do this. I've tried to blacklist the module alias for the PCI device, but it seems to be ignored: $ cat /sys/bus/pci/devices/0000\:00\:1a.0/modalias pci:v00008086d00003B3Csv0000104Dsd00009071bc0Csc03i20 $ cat /etc/modprobe.d/blacklist blacklist pci:v00008086d00003B3Csv0000104Dsd00009071bc0Csc03i20 How do I ensure that this specific PCI device is never automatically activated, without disabling its driver altogether? -edit- The module was renamed recently, now the following works from userland: echo "0000:00:1a.0" > /sys/bus/pci/drivers/ehci-pci/unbind Still, I'm looking for a way to stop the kernel from binding that device in the first place.

  • Virtualhost one https site, the rest http

    - by RJP1
    I have a linode server with Apache2 running a handful of sites with virtualhosting. All sites work fine on port 80, but one site has a ssl certificate and also runs okay. My problem is as follows: The non-https sites, if visiting https://domain.com - show the contents of the only secure site... Is there a way of disabling the *:443 match for these non-secure sites? Thanks! EDIT (more information): Here's a typical config in sites-available for a normal insecure http site: <VirtualHost *:80> ServerName www.insecure.com ServerAlias insecure.com ... </VirtualHost> The secure https site is as follows: <VirtualHost *:80> ServerName www.secure.com Redirect permanent / https://secure.com/ </VirtualHost> <VirtualHost *:80> ServerName secure.com RedirectMatch permanent ^/(.*) https://secure.com/$1 </VirtualHost> <VirtualHost *:443> SSLEngine on SSLProtocol all SSLCertificateChainFile ... SSLCertificateFile ... SSLCertificateKeyFile ... SSLCACertificateFile ... ServerName secure.com ServerAlias secure.com ... </VirtualHost> So, visiting: http:/insecure.com - works http:/www.insecure.com - works http:/secure.com - redirects to https:/secure.com - works http:/www.secure.com - redirects to https:/secure.com - works https:/insecure.com - shows https:/secure.com - WRONG!

  • Creating a link to name changing directory

    - by groove1534
    I have an Ubuntu 12.04 installed using wubi + Win7. I'm trying to create a link to "my documents" directory which located in my C drive: C:\Users\Myuser\My Documents\ Since the Ubuntu is installed in D:\, which is the "host", my C drive is accessible via /media/some_changing_hex. This hex get changed each time I restart my machine. So I need, somehow, to create a link that uses regex OR a link that somehow gets the the first (in this case - only) subdirectory in /media (something like all_subdirectories[0]). So how do I do that?

  • /var/tmp and file lifetime

    - by clorz
    Hi everyone I've got a cronjob that runs every minute and checks existence of a certain file. If there's no such file, job silently ends. If there is a file, then another script is started. That script removes the file when done. Its execution time can take up to 20 minutes. My questions are: Are there any flaws in this scheme? Is it ok to store such file in tmp? Can I be shure that nothing will attempt to remove it?

  • I can connect to Samba server but cannot access shares.

    - by jlego
    I'm having trouble getting samba sharing working to access shares. I have setup a stand-alone box running Fedora 16 to use as a file-sharing and web development server. It needs to be able to share files with a Windows 7 PC and a Mac running OSX Snow Leopard. I've setup Samba using the Samba configuration GUI tool on Fedora. Added users to Fedora and connected them as Samba users (which are the same as the Windows and Mac usernames and passwords). The workgroup name is the same as the Windows workgroup. Authentication is set to User. I've allowed Samba and Samba client through the firewall and set the ethernet to a trusted port in the firewall. Both the Windows and Mac machines can connect to the server and view the shares, however when trying to access the shares, Windows throws error: 0x80070035 " Windows cannot access \\SERVERNAME\ShareName." Windows user is not prompted for a username or password when accessing the server (found under "Network Places"). This also happens when connecting with the IP rather than the server name. The Mac can also connect to the server and see the shares but when choosing a share gives the error: The original item for ShareName cannot be found. When connecting via IP, the Mac user is prompted for username and password, which when authenticated gives a list of shares, however when choosing a share to connect to, the error is displayed and the user cannot access the share. Since both machines are acting similarly when trying to access the shares, I assume it is an issue with how Samba is configured. smb.conf: [global] workgroup = workgroup server string = Server log file = /var/log/samba/log.%m max log size = 50 security = user load printers = yes cups options = raw printcap name = lpstat printing = cups [homes] comment = Home Directories browseable = no writable = yes [printers] comment = All Printers path = /var/spool/samba browseable = yes printable = yes [FileServ] comment = FileShare path = /media/FileServ read only = no browseable = yes valid users = user1, user2 [webdev] comment = Web development path = /var/www/html/webdev read only = no browseable = yes valid users = user1 How do I get samba sharing working? UPDATE: I Figured it out, it was because I was sharing a second hard drive. See checked answer below. Speculation 1: Before this box I had another box with the same version of fedora installed (16) and samba working for these same computers. I started up the old machine and copied the smb.conf file from the old machine to the new one (editing the share definitions for the new shares of course) and I still get the same errors on both client machines. The only difference in environment is the hardware and the router. On the old machine the router received a dynamic public IP and assigned dynamic private IPs to each device on the network while the new machine is connected to a router that has a static public IP (still dynamic internal IPs though.) Could either one of these be affecting Samba? Speculation 2: As the directory I am trying to share is actually an entire internal disk, I have tried these things: 1.) changing the owner of the mounted disk from root to my user (which is the same username as on the Windows machine) 2.) made a share that only included one of the folders on the disk instead of the entire disk with my user again as the owner. Both tests failed giving me the same errors regarding the network address. Speculation 3: Whenever I try to connect to the share on the Windows 7 client I am prompted for my username and password. When I enter the correct credentials I get an access denied message. However I did notice that under the login box "domain: WINDOWS-PC-NAME" is listed. I believe this could very well be the problem. Speculation 4: So I've completely reinstalled Fedora and Samba now. I've created a share on the first harddrive (one fedora is installed on) and I can access that fine from Windows. However when I try to share any data on the second disk, I am receiving the same error. This I believe is the problem. I think I need to change some things in fstab or fdisk or something. Speculation 5: So in fstab I mapped the drive to automount in a folder which works correctly. I also added the samba_share_t SElinux label to the mountpoint directory which now allows me to access the shares on the Windows machine, however I cannot see any of the files in the directory on the windows machine. (They are there, I can see them in the fedora file browser locally)

  • Enter response once prompt returns?

    - by mjb
    It's neither a secure idea nor one I'd recommend elsewhere, but I have a situation when occasionally it takes a while for my Ansible ad-hoc command to respond. I'd love to pipe or args or whatever is needed to push the required text into the prompt so I can walk away and know it will finish. Ex: $ ansible all -m shell -a "reboot" --ask-pass Password: blah blah blah it worked I'd love to send an argument or << or something to get the password in. Is that possible?

  • IPTables configuration help

    - by Sam
    I'm after some help with setting up IPTables. Mostly the configuration is working, but regardless of what I try I cannot allow localhost to access the local Apache only (i.e. localhost to access localhost:80 only). Here is my script: !/bin/bash Allow root to access external web and ftp iptables -t filter -A OUTPUT -p tcp --dport 21 --match owner --uid-owner 0 -j ACCEPT iptables -t filter -A OUTPUT -p tcp --dport 80 --match owner --uid-owner 0 -j ACCEPT Allow DNS queries iptables -A OUTPUT -p udp --dport 53 -j ACCEPT iptables -A OUTPUT -p tcp --dport 53 -j ACCEPT Allow in and outbound SSH to/from any server iptables -A INPUT -p tcp -s 0/0 --dport 22 -j ACCEPT iptables -A OUTPUT -p tcp -d 0/0 --sport 22 -j ACCEPT Accept ICMP requests iptables -A INPUT -p icmp -s 0/0 -j ACCEPT iptables -A OUTPUT -p icmp -d 0/0 -j ACCEPT Accept connections from any local machines but disallow localhost access to networked machines iptables -A INPUT -s 10.0.1.0/24 -j ACCEPT iptables -A OUTPUT -d 10.0.1.0/24 -j DROP Drop ALL other traffic iptables -A OUTPUT -p tcp -d 0/0 -j DROP iptables -A OUTPUT -p udp -d 0/0 -j DROP Now I have tried many permutations and I'm obviously missing everything. I place them above the in/out bound SSH to/from, so it's not the precedence order. If someone could give me the heads up on allowing only the local machine to access the local web server, that'd be great. Cheers guys.

  • Apache intermittently aborting requests

    - by Adam Phillips
    I have just been dealing with a problem whereby http requests are being aborted, seemingly at random. On any particular page in the website, when you opened a page, a number of the assets (img, css, etc) failed to load. If you refreshed, the page may work fine, the same set of assets may fail to load or different assets may fail to load. The net tab in firefox was returning 'Aborted' in the HTTP status code column for the failed assets, even tho in the case of images, the image previews were still working. There was nothing in any of the apache logs about the requests that failed, however since it seemed to point to an apache issue, we restarted apache. The first time we tried, it made no difference but about 10 minutes later, in the absence of a better solution we tried again. Bizarrely, the problem disappeared immeadiately. So now the site seems to be running fine again but its rather unsettling, both the intermittent nature of the problem and the lack of an explanation for its resolution. Has anyone seen anything like this before and if so did you find out the reason behind it? Many Thanks

  • Access Derby for CDP Server

    - by Skudd
    I am working on a project that requires accessing the Derby database behind a CDP Backup Server. From what limited research I've been able to complete, I have found that it is possible to access Derby databases over TCP, but I'm at a complete loss for this. I'm looking to connect via PHP eventually, but first I need to know if this is at all possible with an out-of-the-box CDP server. Answers are, as always, appreciated. Thanks!

For example: rsync -ax \ --partial --delete --delete-excluded --inplace \ --exclude-from=/tmp/temp_excludes \ --link-dest=/Volumes/Backup/current \ /Users /Volumes/Backup/2012-06-25 This works very well as long as I start the process from my normal user account. Though as soon as I start the process using sudo it behaves erradically, meaning that rsync copies all the unchanged files instead of hard-linking them. Since sudo modifies the environment, I've already also tried sudo -E in conjunction with making sure that my sudoers file has the corresponding option set. Well, that didn't work either. So, the question is, how can I run rsync using sudo? Whereas the above example only shows a backup of the Users directory, I also need to backup some system files that I can only access as root.
