  • Setting per-directory umask using ACLs

    - by Yarin
    We want to mimic the behavior of a system-wide 002 umask on a certain directory foo, in order to ensure the following result: All sub-directories created underneath foo will have 775 permissions All files created underneath foo and subdirectories will have 664 permissions 1 and 2 will happen for files/dirs created by all users, including root, and all daemons. Assuming that ACL is enabled on our partition, this is the command we've come up with: setfacl -R -d -m mask:002 foo This seems to be working- I'm basically just looking for confirmation. Is this the most effective way to apply a per-directory umask with an ACL?

  • rsync without password, none of google (server fault) tutorials worked

    - by Jake Armstrong
    I need to use rsync for a daily backup operation and in the past (on different servers) I managed to just use a rsa key etc, but now none of google (serverfault) tutorials work at all. It keeps asking me for a password. I have webmin and ssh/root access to both servers. My steps: create a key on server 1 send key.pub to server 2 add key.pub to .ssh/authorized_keys chmod 700 .ssh/authorized_keys go back to server 1 and try rsync and it keep asking for password... rsync command: rsync -avz -e ssh file.txt root@server2:/root EDIT: well, I cleaned up everything and this time, instead of inserting a custom name to the key I used the standard one on server1. sent the .pub to server2 and it worked as a charm... So the answer is that server1's ssh wasn't even using the right key...

  • What is the best vfat driver for FUSE? (Lightweight, not mountlo)

    - by Vi
    FUSE filesystem list show some FuseFat and FatFuse. Both are old, FatFuse is read-only , FuseFat is non-buildable and probably depends on glib. Now I'm using mountlo for the task (mounting USB drives in generic way without root access or suid things (except of fusermount itself)), but it looks too big for such task. Is there good vfat FUSE driver?

  • DNS propagation

    - by Paddington
    I have 1 primary DNS server (ns1.mydomain.com) running on Fedora and 2 secondary ones (ns2 and ns3). DNS changes made on my web servers first goes to the primary name server and then propagates to the secondary servers. After making a DNS change on a domain on the web server, I can't see the new dns information on my ns1 when I perform: dig @ns1 A blahblah.com I then went to the master records on the names server (uses named) in the directory /var/named/run-root/var/named/masters and I see the A record has been updated appropriately. Tailing the logs /var/log/messages is not showing any errors. What could be the issue?

  • How can one keep secure regular backups of his desktop on a remote server through aDSL? [on hold]

    - by Antonis Christofides
    I'm a system administrator and I use rsnapshot to backup some servers, duplicity for some others. Both work fine, each one with advantages and disadvantages. Despite that, I am at a loss on how to backup my own private files. I'd use duplicity to automatically backup my files to a remote server; but the problem is that once in a while I must do a full backup. My emails and important files are 9G, and I expect this to increase. Uploading through aDSL at 1Mbit would be 20 hours. Too much. rsnapshot doesn't require periodic full backups (only the first time), but it must be running on the remote server and have a means to connect to my computer; if the server is compromised (or simply if the NSA decides to use it), my own machine is also compromised. Not good. The only solution I've come up with is use encfs, use unison to synchronize the files to a remote server, and use duplicity or rsnapshot on the remote server to backup these files. In that case, the question is whether I can sync the files on many computers; is it possible for encfs to be used with the same key on many computers? I also think that if I append one character to the unencrypted file, its encrypted encfs counterpart might change a lot, so that incrementals with duplicity would be less efficient—but not a big deal. Maybe also, when I need to restore a file, finding the correct file to restore could be a pain, because of filename encryption. I wonder whether there is any other possibility that I've overlooked. Maybe I'm asking too much for my personal use, and I should settle with an external disk?

  • 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 :@

  • umask is being ignored on Gentoo while creating new files

    - by drcelus
    I have a server running Gentoo and hosting a drupal installation. Whenever a Drupal update is executed, the directory permissions of the updated module turn from 755 to 744 preventing the application from accessing the files. The umask is defined as 022 under /etc/profile and the Apache server is running under user and group nobody. I believe this has nothing to do with the drupal installation since if I create a directory as root, the same happens, it is created with 744 permissions, since the umask is 022 shouldn't it be created as 755 ? Why is the umask being ignored and how do I tell the server to create the directories with permission 755 ?

  • Interested in scp recipe for sftp [closed]

    - by GJZ
    You wrote in a reply this Blockquote The problem is that sftp runs as the user's id -- first, the sftp client ssh's into the target host as the given user, then runs sftp-server. Since sftp-server is running as a regular user, it has no way to "give away" a file (change owner of a file). However, if you are able to use scp, and assign a key pair to each user, you can get around this. This involves adding a user's key to root's ~/.ssh/authorized_keys file, with a "command=" parameter to force it to run a script that sanitizes and alters the arguments of the server-side scp program. I've used this technique before to set up an anonymous scp dropbox that allowed anyone to submit a file, and ensure that no one could retrieve submitted files and also prevent overwrites. If you are open to this technique, let me know and I'll update this post with a quick recipe. We are interested in this scp quick recipe for our community services file sharing. Best Regards, Gert Jan Zeilstra

  • Size of modules within initrd

    - by LiKao
    I am currently trying to manually replace the kernel within ubuntu-core on an embedded device with a custom kernel. However when I try to update the initrd my initrd becomes much bigger. Here is what I did: Extract the initrd that was shipped with ubuntu Make a list of all modules within the old initrd get the same modules from the new module director at /lib/modules/new_kernel_version add these modules to the initrd and remove the old ones If I do this my initrd becomes quite bigger than the original one, so I checked the individual modules. I picked the btrfs.ko filesystem driver as an example. So by comparing these two modules I noticed the one I just picked into the initrd was much bigger, which caused the difference in size. -rw-r--r-- 1 root root 999K Nov 14 15:06 btrfs.ko For the btrfs.ko within the shipped initrd. -rw-r--r-- 1 root root 7.2M Nov 14 15:08 btrfs.ko For the new btrfs.ko. What is different between these two modules? Could this be caused by some faulty setting for the new kernel? When producing the kernel I copied /proc/config.gz and used make oldconfig to update it, so all optimisations should be the same for both kernels. Or is there something else which is being done to the modules before they are put into the initrd? Maybe is there even some better way to build a new initrd for the new kernel in ubuntu altogether. Update: I just also tested with an initrd which I created from scratch using the mkinitrfs command within ubuntu, and it has the same size difference that I found for the initrd I manually updated.

  • Server unresponsive, messages shown on console but not in log files

    - by raistlin majere
    I'm using Ubuntu Server 10.04.4, and once in a while the server hangs (once a month) and is totally unresponsive. The tty is flooded with messages like these. The problem is that these messages are not in my log files after reboot. How to log these messages so that I can analyze them later? In the current logs I can't see anything that would tell me why this is happening. I would also appreciate if anybody can tell from those messages what's going on. This server is a guest virtual machine. The host server is also Ubuntu server 10.04 with KVM/QEMU.

  • Any good resources on setting up an ubuntu virtual machine for web development?

    - by Relequestual
    I'm currently on my placement year at uni with 4 months left. Before working at my current place, I have not used a nix environment for web development and have used WAMP. Over the past year I have found some very interesting new tech that requires a bit more than my shared hosting even to play with (eg node.js, RoR 3). At work we use a Virtual Machine for development, but that's all been set up and configured to match the live servers, and is managed with a Puppet server. Are there any really good resources for setting up and configuring an Ubuntu VM as a web server? Work currently uses Ubuntu so I would assume this is a good OS to use. I do of course know how to use google, but the noise ratio is just too big, so thought I'd ask here, as I know many of you will have a ton of bookmarks. Cheers.

  • LVM Extend... not sure the filesystem

    - by Dan
    I would like to extend my LVM partition. First I did lvextend -L +100G /dev/server/home Now I still have to extend the filesystem. The tutorials tell me to use resize2fs, but that only works for ext2 and ext3. I'm not even sure what filesystem I have... fdisk /dev/server/home/ doesn't work... how do I know what kind of filesystem I have on my lvm partition?

  • 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.

  • When using gt5 in my home directory I get a blank page.

    - by MT
    When using gt5 in various directories on my system (including my home directory) I get blank results. If I limit the max-depth enough, I get results. For example, in my home directory 'gt5 --max-depth 2' produces a listing, while 'gt5 --max-depth 3' produces a blank page. I've noticed that the temporary html file that gets created in tmp (such as '/tmp/gt5.9035.kJVM08Y9/gt5.html' is a zero-byte file. I can successfully do a du in the same directory (which is what I thought gt5 was using), so I'm not sure what to check?

  • Batch converting video from avc1 to xvid

    - by Tommy Brunn
    I need a way to batch convert 720p video files from avc1 to xvid in Ubuntu 10.04. I'm not terribly concerned about file size, but I do wish to retain the picture quality as much as possible. I believe the audio is encoded as aac, which is fine for my purposes. What would be the best and easiest way to do this? I've tried using Handbrake. During my first attempt, I had it using ffmpeg to convert to MPEG-4, but that just gave me a super-low quality video at twice the file size. Trying h.264 now, so we'll see how that works out. But just in case it doesn't pan out so well, what other ways do you recommend? I was thinking I'd write a bash script to reencode the files one by one, but the problem is that I have very little knowledge about codecs and containers and whatnot - so I wouldn't know what parameters I would pass ffmpeg/mencoder.

    This question already has an answer here: Hostnames - What are they all about? 5 answers Setting the hostname: FQDN or short name? 6 answers It's thought that for the hostname should be used FQDN. I have a doubts about whether using: host.domain.ltd and domain.ltd for the hostname is the same thing and will be equally correct / acceptable? I'm willing to use domain.ltd for the hostname. Is it alright?
