  • Is there a way to rsync in batches?

    - by Chris
    I have a huge chunk of data (11G) in a subversion repository that I'm using rsync to migrate to Alfresco, which lucene indexes new files as they hit the file system. I'm using a dav mount as a proxy to allow me to rsync. The issue I'm having is the indexing post-rsync is quite an expensive operation for such a huge chunk of data, so I was wondering whether there's a way I could logically separate the rsync into identically-sized batches (say 500MB each) so I could schedule them in cron. At the moment, I'm traversing the top level folders and taking the smallest ones across first, but once I'm done with those, the much larger sub-directories are going to be quite troublesome. Please let me know if you need any further info. Thanks in advance.

  • How do you enable webcam support in Facebook for Ubuntu 10.04?

    - by Jonathan
    I think I have finally arrived at an insolvable equation: Chromium v.7 + Ubuntu 10.04 + Sun Java 6 + Webcam + Facebook + Flash 10 = non-functional All of those items listed above are potential points of failure in this situation, and any help narrowing them down would be fantastic. I am simply trying to enable webcame support directly through Facebooks website. Forum searches and the usual googling turn up few posts related to this specific equation. Two of the major suggestions include: 1) Installing the Sun (I refuse to say oracle sob)-provided Java implementation instead of the OpenJDK normally installed in Ubuntu. And yes, after installing it, I did update all my default supports to use the sun commands over the openjdk. 2) Somehow enabling Facebook as a permitted site to access my webcam using Flash settings. I have not been able to explore option 2 because I cannot find a way to adjust the Flash settings in chromium 7. Other factors that do not help include the fact that I am pretty sure facebook changes its webcam interface every 10 seconds just to keep troubleshooters and support personnel on their toes. If anyone has a OTP that informs us of the next shift in the app, a leak would be greatly appreciated!

  • what to do when ctrl-c can't kill a process?

    - by Dustin Boswell
    Ctrl-c doesn't always work to kill the current process (for instance, if that process is busy in certain network operations). In that case, you just see "^C" by your cursor, and can't do much else. What's the easiest way to force that process to die now without losing my terminal? Summary of answers below: Usually, you can Ctrl-z to put the process to sleep, and then do "kill -9 process-pid", where you find the process's pid with 'ps' and other tools. On Bash (and possibly other shells) you can do "kill -9 %1" (or '%N' in general) which is easier. If Ctrl-z doesn't work, you'll have to open another terminal and kill from there.

  • deploy git project and permission issue

    - by nixer
    I have project hosted with gitolite on my own server, and I would like to deploy the whole project from gitolite bare repository to apache accessible place, by post-receive hook. I have next hook content echo "starting deploy..." WWW_ROOT="/var/www_virt.hosting/domain_name/htdocs/" GIT_WORK_TREE=$WWW_ROOT git checkout -f exec chmod -R 750 $WWW_ROOT exec chown -R www-data:www-data $WWW_ROOT echo "finished" hook can't be finished without any error message. chmod: changing permissions of `/var/www_virt.hosting/domain_name/file_name': Operation not permitted means that git has no enough right to make it. The git source path is /var/lib/gitolite/project.git/, which is owned by gitolite:gitolite And with this permissions redmine (been working under www-data user) can't achieve git repository to fetch all changes The whole project should be placed here: /var/www_virt.hosting/domain_name/htdocs/, which is owned by www-data:www-data. What changes I should do, to work properly post-receive hook in git, and redmine with repository ? what I did, is: # id www-data uid=33(www-data) gid=33(www-data) groups=33(www-data),119(gitolite) # id gitolite uid=110(gitolite) gid=119(gitolite) groups=119(gitolite),33(www-data) does not helped. I want to have no any problem to work apache (to view project), redmine to read source files for project (under git) and git (doing deploy to www-data accessible path) what should I do ?

  • Rendering a frame is producing noise from speakers in Windows and Linux

    - by Robber
    When any hardware accelerated application is rendering a frame (or many of them) a very short noise is coming from my speakers. This can be a game, a WebGL application or XBMC. When the application/game is rendering many frames per second (like most of them do) the noise is a continuous buzzing that gets higher pitched with higher framerates. This applies to Linux and Windows, so I'd assume it's a hardware problem. The current hardware in the PC is: CPU: Core2Quad Q9550 GPU: Radeon HD 5770 RAM: 2x2GB DDR2 Motherboard: Asus P5QLD PRO PSU: be quiet! Pure Power 530W Screen and speakers: Old 720p LCD TV connected via VGA and aux cable Muting the TV stops the noise, muting Windows doesn't. I tried replacing the PSU first (used a Tagan 700W PSU before) because I thought it was a power problem. It wasn't. I tried replacing the motherboard (used a ASUS P5B SE before) next because I thought it was a sound card problem. It wasn't. I tried the GPU in a different PC because I thought it was a broken graphics card. It worked perfectly fine in the other PC. I thought it might be interference, but moving the audio cable around changes absolutely nothing. I tried using an HDMI cable instead and that did work, but is not an option since my TV has only one HDMI input and I need that for my PS3.

  • My NTFS Partition keeps becoming "unusable" on Ubuntu, Any Ideas?

    - by gopherman
    I just purchased a new 2TB Drive External Seagate, My main system uses both Windows and Ubuntu So I am pretty much stuck with keeping my drive as NTFS. I have done this without any problems before but since I got this new drive I have been having issues. When I first load up Ubuntu the drive mounts and runs fine, after an unspecified amount of time i start getting Input/Output errors when accessing the drive. When I goto the Disk Utility I get a message stating the drive is "Unknown or Unused", If I disconnect and reconnect the drive or reboot everything is fine again. There's no errors coming up with S.M.A.R.T and it seems to work fine while under windows. Any thoughts?

  • APF, IPTABLES, Fedora 15 - Not blocking correctly

    - by RichardW11
    I just got a new remote server which came with Fedora 15. I first tried to run APF but it gave me this error "apf(18031): {glob} unable to load iptables module (ip_tables), aborting.". Which I then set SET_MONOKERN="0" to SET_MONOKERN="1" to resolve the problem. However, with my config file showing BLK_P2P_PORTS="1214,2323,4660_4678,6257,6699,6346,6347,6881_6889,6346,7778" The ports show up as closed, instead of being filtered. Any idea why this would be happening? 22/tcp open ssh 80/tcp open http 443/tcp open https 2323/tcp closed 3d-nfsd 4662/tcp closed edonkey 6346/tcp closed gnutella 6699/tcp closed napster 6881/tcp closed bittorrent-tracker 7778/tcp closed interwise

  • Ubuntu X doesn't start

    - by den-javamaniac
    I'm running desktop Ubuntu 9.10 on my Dell laptop. Previously it was Ubuntu 9.04. After some period of time (lets say 3-4 months) my X fails to start automatically after some restart calls. If that takes place my network manager applet doesn't start either (after I do startx). Can any one point out what I'm missing/what's the problem?

  • VMware - Broadcom 1000Gbps NIC does not link at 100Mbps to a Cisco switch port

    - by Spirit
    Today we've stumbled on a very awkward situation with our VMWare Server. The server is with ESX 3.5 that has a 1Gbps NIC. We bought a brand new managed Cisco Linksys switch with 10/100Mbps interface ports but when we plugged the cable in one of the ports the link simply does not wanted to activate :S... Does anyone with more VMware experience have ever had similar problem? From what I know is that 1Gbps NICs are backwards compatible with 100Mbps switches. This is what we've tryed so far but with no success: Tryed: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004089 Tryed to modify the /etc/modules.conf folowing the guide from this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=813 After the changes I have restarted the networking services using # service network restart, # service mgmt-vmware restart and # service vmware-vpxa restart It seems that no matter how many times, or whatever approach/method (GUI or Shell) we try to change the speed and duplex of the network adapter and to force it to 100mbps it only accepts 1Gbps .. I am starting to go nuts :@

  • What is the cleanest way to upgrade Fedora and also my individual installs while keeping /home?

    - by Don
    I am a professional programmer, using Fedora 10 (and a host of other packages individually installed). I use my system to telecommute. Every year or so, I go through the ritual dance, usually with a second computer and a KVM switch as I don't have office space for two monitors, to build the next version of Fedora and install all my favorite apps. Is there a better way? At least a nice way to keep track of what I need to 'add on' so that I don't have to manually install my app collection? Also, I keep /home on a separate raid-ed drive set so I can also fall prey to 'old-config-file-itis'.

  • Looking for advice on using dd to backup a dual boot laptop.

    - by AvatarOfChronos
    My questions boils down to this. If I do "dd if=/dev/sda of=usbdrive" can anybody confirm that this will get everything including mbr/partition information/all four partitions and create a drive that I can swap with the failing internal drive without losing anything? If this is done while the computer is running will it still copy everything? At this point I'm afraid to shutdown the computer for fear of it never starting again. Secondly, how tolerant is dd of failing drives? Has anybody used it to recover a half dead drive before that can share any potential pitfalls? Did it get the data ok or is this going to be a hope for the best kind of situation? And lastly, If the usbdrive is larger than the failing internal drive I'll still be able to expand the partitions later so I'm not losing space? this last part seems silly to ask but with my current streak of bad luck I'll end up overwriting some magic bit and forever turning a 640gb hdd into a 500gb hdd. Also if anybody has a better solution to create a complete clone that gets everything I'm all for hearing about it. PostScript: I had been making periodic backups however when whatever miasma that killed the laptop struck it also got the NAS :( Post PostScript: both devices were on a UPS system.

  • Why doesn't SSHFS let me look into a mounted directory?

    - by Jan
    I use SSHFS to mount a directory on a remote server. There is a user xxx on client and server. UID and GID are identical on both boxes. I use sshfs -o kernel_cache -o auto_cache -o reconnect -o compression=no \ -o cache_timeout=600 -o ServerAliveInterval=15 \ [email protected]:/mnt/content /home/xxx/path_to/content to mount the directory on the remote server. When I log in as xxx on the client I have no problems. I can cd into /home/xxx/path_to/content. But when I log in on the client as another user zzz and then $ ls -l /home/xxx/path_to I get this d????????? ? ? ? ? ? content and on $ ls -l /home/xxx/path_to/content I get ls: cannot access content: Permission denied When I do $ ls -l /mnt on the remote server I get drwxr-xr-x 6 xxx xxx 4096 2011-07-25 12:51 content What am I doing wrong? The permissions seem to be correct to me. Am I wrong?

  • How to generate new CSRs for TLS use in sendmail?

    - by Mikey B
    SendMail 8.13.8 | CentOS 5.x Hi Guys, I'm using ca-signed TLS certificates on my sendmail server and they are up for renewal soon. Our new CA doesn't like our old CSR so I need to generate a new CSR. Can someone point me to the procedure for doing this (without affecting the production certs that are already in use)? I'm paranoid of overwriting the old TLS certs in the process of generating a CSR. Most of the instructions I've found are for implementing self-signed TLS certs -- which isn't an option for me at this time. I'm thinking it would something like: openssl req -new -nodes -out new-tls.csr -keyout new-tls-private.key But I wasn't sure if I was missing some options there such as the -x509 option... -M

  • Triple-Boot + 4 partition Limit

    - by dsimcha
    I just bought a new hard drive so that I could convert my XP-only machine into an XP-Ubuntu-Windows 7 triple boot machine. Since the drive is absurdly huge (1 TB) I wouldn't mind throwing ReactOS into the mix, too. I just found out that master boot records are limited to 4 entries, meaning 4 primary partitions. I had Windows XP set up on my old drive as a boot partition, a program files partition and a media partition. Since I really didn't want to install XP from scratch, I cloned this setup on my new drive. This leaves me one MBR partition entry for installing Windows 7, Ubuntu and ReactOS. I'd like to avoid having to install XP from scratch like the plague, partly because it's supposed to be a safety net in case things go wrong with my other OS's and because I've invested a lot of time getting it set up exactly the way I like it. Here are the options I've considered and why I don't like them: Install Windows 7 on my media partition. This would work, but I prefer to keep my media partition completely separate from any OS, so that I can reformat an OS partition without affecting my media partition at all. Use wubi or something to install Ubuntu in the same partition as something else. Again, this is brittle. Move all my media to a logical drive on an extended partition. Create another logical drive on this extended partition for Ubuntu. The problem here is that extended partitions are rather brittle--if you nuke one, it renders the rest useless. Just put the old drive back in my computer and run XP off it. Use the new one for the other OS's. The problem here is that the old drive is slower and uses extra power, generates extra heat, etc. Can anyone suggest any other possibilities that I may have overlooked?

  • Do you know a script for email round trip monitoring?

    - by crazyfr
    Do you know a simple script that can do email round trip monitoring ? I want to monitor email service on A. I install the script on B. B sends an email to A A sends an auto-reply to B B knows that email service is working well. B restarts this test every 30min. If B didn't received replies, it sends an alert message. B could also monitor round-trip delay of emails. I have not access to the email service, I can only ask new end user email and configure auto-reply. B is an Ubuntu. Thanks!

  • I just deleted "/bin". What's the best way to recover?

    - by Tom Marthenal
    I just ran (not on purpose!) rm -rf /bin. I've booted down the computer and am using Finnix to try to recover from it. I have succeeded in mounting the drive, and confirmed that, yes, the entire /bin folder is deleted. Is it possible to recover from this without reinstalling the OS? I'm thinking that I could setup a VM with the same OS and architecture (Ubuntu Server 11.10 alpha release, x86) and install all the packages I had installed on the server, then just copy the /bin folder. Will this work? Am I better off just starting over?

    Is it possible to do the following in Ubuntu? If so can someone point me in the right direction. Say you want to set a keyboard shortcut to do the following: For examples sake, set Alt+F to open Firefox and maximize it, but only if Firefox is not already running. If it is running and not maximized, then maximize the most recently touched Firefox window. If it is maximized, then minimize Firefox. Thanks, Joe
