  • How do I rsync an entire folder based on the existence of a specific file type in that folder

    - by inquam
    I have a server set up that receives movies to a folder. I then serve these movies using DLNA. But in the initial folder where they end up all kind of files end up. Pictures, music, documents etc. I thought I'd fix this by running the following script inside that folder rsync -rvt --include='*/' --include='*.avi' --include='*.mkv' --exclude='*' . ../Movies/ This works and scans the given folder and moves all the found movies of the given extension types to the Movies folder. But I wonder if there is anyway to tell rsync to if a folder if found that includes a movie of the given extension types, sync the entire folder. Including other files such as .srt. This is to make it easier for me to get subtitles moved along with the movie. I have a solution figured out via a script made in php (yea, I actually do most of my scripting in linux using php... just a habbit that stuck a long time ago). But if rsync can handle it from the start that would be super. Also, I have noticed that this line of rsync actually copies all the root folders in the given folder. If no movie is in the folder it will create an empty folder. How do I prevent rsync from doing this... and saving me the trouble of deleting all folder in Movies that are empty.

  • Using screen to monitor non-interactive scripts (or some other solution)

    - by Michael
    I have some autonomous scripts that run commands on remote machines over ssh. These scripts rely on getting stdout, stderr, and the return code of each command run. I want to be able to monitor the progress of the scripts on each target machine so that I can see if something has hung and possibly intervene if necessary. My initial idea was to have the scripts run commands in a screen session, so that the person monitoring could simply attach to the session with screen -x. However, it was hard to do that from a script since screen is an interactive program. I can send a command to the screen session with screen -S session -X stuff "command^M", but then I don't get the output and return code that I need back. My second idea was to put script /path/to/log in ~/.bash_profile and log the entire session to a file. Then the monitoring person could simply tail the log file. However, this doesn't provide the interactivity that I was looking for. Any ideas on how to solve this problem?

  • Enable FTP Publishing on IIS7?

    - by David Lively
    I've followed the steps in http://learn.iis.net/page.aspx/303/adding-ftp-to-a-web-site/ However, when I get to the part where it says to click "add ftp publishing to website", the option is not visible in the IIS management console. I've verified that the "FTP Publishing Service" is installed in the server manager, and I can see it running in the services applet and via netstat -a. Suggestions?

  • reaching constant video bitrate by using ffmpeg

    - by sebastian
    We use ffmpeg and a transcoding script for transcoding and want to make some batch files which we can use for transcoding. For example I use a parameter called video_kbit and if I am writing in 30000 it should reach 30 Mbit. Of course if I use 6000 as parameter it should reach 6 MBit as well, so I have one script which reaches every video bitrate I want. As my settings are now, I only reach 18.1 Mbit. Only when I use 15000 as a parameter I am reaching my goal for a constant video bitrate of 15 MBit. If I use 8000 as parameter I get 10.1 MBit as a result. So under 15000, I get a higher bitrate and over 15000, I get a lower bitrate than I want. My presettings are: ffmpeg -threads "4" -i "$2" -f mp4 -c:v libx264 -crf 1 \ -bufsize 30000k -maxrate ${FC_PARAM_video_kbit}k \ -acodec libfaac -ac 2 -ab ${FC_PARAM_audio_kbit}k -ar 44100 \ -pix_fmt yuv420p -vf scale=${FC_PARAM_width}:${FC_PARAM_height} -y "$3" And I am using these parameters: FC_PARAM_video_kbit = 30000 FC_PARAM_audio_kbit = 192 FC_PARAM_width = 1920 FC_PARAM_height = 1080 I have tried using a higher bufsize and using profile:v and level settings, but nothing got me near the constant video bitrate of 30000 Mbit. Do you guys have any ideas or suggestions for a better way to reach my goal?

  • What else can I do to secure my Linux server?

    - by eric01
    I want to put a web application on my Linux server: I will first explain to you what the web app will do and then I will tell you what I did so far to secure my brand new Linux system. The app will be a classified ads website (like gumtree.co.uk) where users can sell their items, upload images, send to and receive emails from the admin. It will use SSL for some pages. I will need SSH. So far, what I did to secure my stock Ubuntu (latest version) is the following: NOTE: I probably did some things that will prevent the application from doing all its tasks, so please let me know of that. My machine's sole purpose will be hosting the website. (I put numbers as bullet points so you can refer to them more easily) 1) Firewall I installed Uncomplicated Firewall. Deny IN & OUT by default Rules: Allow IN & OUT: HTTP, IMAP, POP3, SMTP, SSH, UDP port 53 (DNS), UDP port 123 (SNTP), SSL, port 443 (the ones I didn't allow were FTP, NFS, Samba, VNC, CUPS) When I install MySQL & Apache, I will open up Port 3306 IN & OUT. 2) Secure the partition in /etc/fstab, I added the following line at the end: tmpfs /dev/shm tmpfs defaults,rw 0 0 Then in console: mount -o remount /dev/shm 3) Secure the kernel In the file /etc/sysctl.conf, there are a few different filters to uncomment. I didn't know which one was relevant to web app hosting. Which one should I activate? They are the following: A) Turn on Source Address Verification in all interfaces to prevent spoofing attacks B) Uncomment the next line to enable packet forwarding for IPv4 C) Uncomment the next line to enable packet forwarding for IPv6 D) Do no accept ICMP redirects (we are not a router) E) Accept ICMP redirects only for gateways listed in our default gateway list F) Do not send ICMP redirects G) Do not accept IP source route packets (we are not a router) H) Log Martian Packets 4) Configure the passwd file Replace "sh" by "false" for all accounts except user account and root. I also did it for the account called sshd. I am not sure whether it will prevent SSH connection (which I want to use) or if it's something else. 5) Configure the shadow file In the console: passwd -l to lock all accounts except user account. 6) Install rkhunter and chkrootkit 7) Install Bum Disabled those services: "High performance mail server", "unreadable (kerneloops)","unreadable (speech-dispatcher)","Restores DNS" (should this one stay on?) 8) Install Apparmor_profiles 9) Install clamav & freshclam (antivirus and update) What did I do wrong and what should I do more to secure this Linux machine? Thanks a lot in advance

  • query keepalived

    - by tdimmig
    *Note: I have trouble deciding what should go in serverfault and what should go in superuser, if some kindly admin decides this is in the wrong place please move it for me - many thanks. I am implementing a basic HA system with keepalived. I only want to be notified of the failover in the case of hardware failure. I do, however, have the servers switch roles periodically. I have a track_script running on the backup that will vary it's return between 0 and 1 on an interval (once a week, once a month, whatever). Upon returning 0, the priority is raised above that of the master, upon returning 1 the priority is lowered again. This way they trade places on the configured interval. The question: What can I do to tell the difference between a switch caused by my script, and a switch caused because one of the servers died? I certainly want to be notified when there is an actual problem, but not every time the servers change places because of the script. I see that version 1.2.7 has snmp support and I may be able to use it to get some information that could tell me one way or another, but to be honest I've never used snmp before and I don't know how to get the information I want with it (my Google foo failed me).

  • How can I generate filesystem images that are usable on many different virtualization systems?

    - by Mark Longair
    I have written a script that generates a root filesystem image (based on Debian lenny) suitable for User-Mode Linux. (Essentially this script creates a filesystem image, mounts it with a loop device, uses debootstrap to create a lenny install, sets up a static IP for TUN/TAP networking, adds public keys for login by SSH and installs a web application.) These filesystem images work pretty well with UML, but it would be nice to be able to generate similar images that people can use on alternative virtualization software, and I'm not familiar with these options at all. In particular, since the idea is to use this image as a standalone server for testing the web application, it's important that the networking works. I wonder if anyone can suggest what would be involved in customizing such root filesystem images such that they could be used with other virtualization software, such as VMware, Xen or as an Amazon EC2 instance? Two particular concerns are: If such systems don't use a raw filesystem image (e.g. they need headers with metadata or are compressed in some particular way) do there exist tools to convert between the different formats? I assume that in the filesystem, at least /etc/network/interfaces will have to be customized, but are more involved changes likely to be necessary? Many thanks for any suggestions...

  • Reading log files from web application

    - by Egorinsk
    Hi! I want to write a small PHP application for monitoring logs on a Debian server, including syslog logs and Apache/PHP messages. The problem here is that Apache user (www-data) has no access to /var/log directory. What would be the best way to grant an access to logs for PHP application? Let's assume that log files can be really large, like hundreds of megabytes. I have some ideas: Write a shell script that would be run via sudo and tail last 512 Kb of log into a separate file that can be read by application - that's ineffective, because of forking a new process and having to read data twice Add www-data to adm group (that can read logs) - that's insecure Start a PHP process via cron every minute to read logs — that's not very good, because it doesn't allow real-time monitoring. Also, this script will be started even when I don't read logs, and consume CPU time (server is in the cloud, and I'll have to pay for it) Create a hardlink for all log files with lowered permissions - I guess, that won't work because logrotate could recreate log files and they'll change inode number. Start a separate nginx/Apache server under privileged user that may read logs. Maybe anyone got a better solution?

    After an update yesterday my Dell X300 will only boot to a screen with an option to perform 2 memory tests. If I perform these tests, it will only go back to this same screen, offering a choice of memory test again, 86+ or 86+ serial console 115200. This screen is headed - GNU Grub version 1.97 beta 4. This is a full install on my hard drive. How can I get back to booting normally?

  • Preventing back connect in Cpanel servers

    - by Fernando
    We run a Cpanel server and someone gained access to almost all accounts using the following steps: 1) Gained access to an user account due to weak password. Note: this user didn't had shell access. 2) With this user account, he accessed Cpanel and added a cron task. The cron task was a perl script that connected to his IP and he was able to send back shell commands. 3) Having a non jailed shell, he was able to change content of most websites in server specially for users who set their folders to 777 ( Unfortunately a common recommendation and sometimes a requirement for some PHP softwares ). Is there a way to prevent this? We started by disabling cron in Cpanel interface, but this is not enough. I see a lot of other options in which an user could run this perl script. We have a firewall running and blocking uncommon outgoing ports. But he used port 80 and, well, I can't block this port as a lot of processes use them to access things, even Cpanel itself.

  • Ok, i know i messed things up pretty bad..... virtualmin sub domain user taken over root login

    - by Collins Areba
    ok, here is the scenario, i was playing around the import wizard and imported a subdomain i had created on a linode and now im having trouble cause the user i assigned to the subdomain is root. Now when i log into webmin / usermin / virtualmin with my root credentials, i end up administering a sub domain instead of working on the webmin root console. Is there a way of a) deleting the virtualhost completely from usermin using ssh? b) rectifying this ..

  • Why is "start in" needed for Windows scheduled tasks?

    - by GomoX
    We develop a web application that can be deployed on Windows or Linux. The Linux implementation uses cron, and the Windows one uses scheduled tasks to run a single PHP script that processes all scheduled tasks for our system. The task is scheduled using schtasks during the install process, like: This has always worked both under W2003 and W2008. A week ago a customer reported that scheduled tasks were not running. He is running on Windows 2008. We checked over and over and finally solved the issue by entering the folder that contains the .vbs script as the "start in" folder for the scheduled task. This said, there is no way to set up the "start in..." value from schtasks without using an XML definition of the tasks. XML definitions don't work in Windows 2003, so I would have to add windows version detection to the installer, additional testing, etc (I'd like to avoid this if at all possible). The only atypical thing I noticed about the install is that the system is installed in D:\ as opposed to the default C:\Program Files (x86)\, but I don't see how this would matter. All the paths are absolute in all the scripts. Can anyone suggest a reasonable solution for this?

  • Which scripting language to use to asynchronously ssh into equipment, run several commands, parse the output, and save to a file on my computer?

    - by Fujin
    There are several points I'd like to stress in my question. I'd like to login by asynchronously ssh'ing into our infrastructure equipment. Meaning, I do not want to connect to only one device, do all the tasks I need, disconnect, then connect to the next device. I want to connect to several devices at once in order to make the process as fast as possible. By equipment I mean 'infrastructure equipment' and not servers. I say this because I will not have the luxury of saving files to the device then transferring them to myself with scp or another method. The output of the scripts that are run will have to be saved directly to my computer. The output of the commands that are run will need to be cleaned up and parsed. Also I want the outputs of each device to be combined into one nice and neat file, not a separate file for each device. This will all be done from a linux box, using ssh, into devices that all use linux'ish proprietary OSes. My guess is the answer to my question will either be a Bash, Perl, or Python script but I figured it wouldn't hurt to ask and to hear the reasons why one way is better than another. Thanks everyone. EXTRA CREDIT: With you answer, include links to resources that will help create the script I described in the language that you suggested.

  • Firefox, reload without cache check

    - by pmoleri
    It looks like a popular question but it's just the opposite. When I visit a site in Firefox 15 I have two different behaviours when: Pressing enter in the address bar Pressing F5 or the refresh button If I look in the network console I can see that F5 does a lot more requests, most of them about cached resources and with a 304-Not Modified answer. Is there's any shortcut to make a quick refresh? Just like pressing enter on the address bar.

  • can't change wallpaper real time regedit commands

    - by itagomo
    i'm a first time 'SuperUser' poster .. what i want is to programatically change Desktop Wallpaper every few hours .. i'm using a batch file (.bat) and don't want to use other languages or programs, just the pre-installed stuffs with Windows XP .. i've already made my script that will modify values in the Registry reg add "HKCU\Control Panel\Desktop" /v Wallpaper /d "C:\Pictures\picture1.jpg" but it's not taking effect real time even with this command: RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters ,1 ,True need to reboot first to take effect. if i'm going to use Display Properties, it'll show at once. what i've noticed is that changes will take effect real time if it's a .bmp file and not for .jpg images. Second option is to convert JPG to 24-bit BMP files (to look exactly the same, but will triple the file size), but i'm hoping a better way .. i've already googled things but no avail.. i hope you (the helpful reader) can post any .bat or even vbs script to change Desktop Wallpaper instantly with JPG pictures .. hoping there's an answer without installing other apps or scripts ..

  • Can a PCI Graphics card, and AGP be used together?

    - by Everyone
    The question pretty much says it all. I use an old 845GBV board ( to-date reliant upon the integrated graphics processor ). All slots on the board are unused. Lately I've been thinking in terms changing it to a dual monitor so that I can use one console for documentation/help/sample code/whatever, the other one to play with code. Assuming this board can handle a PCI GPU, can an AGP4x board coexist with a PCI GPU?

  • File upload folder permission fastCGI - How to make it writeable?

    - by user6595
    I am using centos 5.7 with cPanel WHM running fastcgi/suEXEC I am trying to make a particular folder writable to allow a script to upload files but seem to be having problems. The folder (and all recursive folders) I want to be writable is: /home/mydomain/public_html/uploads And I want only scripts run by the user "songbanc" to be able to write to this directory. I have tried the following: chown -R songbanc /home/mydomain/public_html/uploads chmod -R 755 /home/mydomain/public_html/uploads But it still doesn't seem to work. The script will only upload files if I set the permissions manually via FTP client to 777. I assume I am misunderstanding how to set permission for users with fastcgi and hopefully someone can help me. Thanks in advance EDIT: Running getfacl on one of the scripts or folders gives the following: # file: home/mydomain/public_html/ripples/1.jpg # owner: songbanc # group: songbanc So it appears that the owner is correct? I'm now totally confused! EDIT 2: The plot thickens... lsattr and chattr are returning Inappropriate ioctl for device While reading flags on...

  • VirtualBox without X server

    - by nccc
    I want to run a guest operating system under a Linux host with VirtualBox, but I don't want to run from within X. I don't want a headless configuration, I don't want to run VirtualBox in the background, I don't want any remote protocols. I just want the guest OS to take control of my console (keyboard, mouse and monitor) and render to the framebuffer directly, not from within an X window. Is this possible?

  • VMware ESX Linux Guest Customization

    - by andyh_ky
    Hello, I am interested in deploying several RHEL 4 Update 8 virtual machines for creation of a test environment. Here are the steps I am taking: In off hours, P2V/V2V the production machines and convert them to templates Deploy the virtual machines with a customization specification that changes hostname, IP address I am interested in how these processes are done and if there are any options for further customization. Are the machines brought on the network when they are powered on, before they are reconfigured? Is there a potential IP address conflict? Is there an option to run additional scripts which reside on the guest as a part of the reconfiguration? For example, restoring an Oracle Database. This is an option with Windows guests and sysprep, but I have been unable to locate anything showing a RHEL equivalent. I am dealing with a multi tier application. The main issue I am attempting to mitigate is that the application servers reference database servers by hostname and in tnsnames files. I am interested in scripting the reconfiguration of the application in the deployment so that the app/db servers are pointing to the test environment. I am OK with placing the 'cleanup' script on the source and executing it after the machine has been brought up. I am interested in the automation of the script's execution post clone/boot, as well as if there could be an IP address conflict. (cross posted to VMTN's ESX 4 community)
