  • How to grant read/write to specific user in any existent or future subdirectory of a given directory? [migrated]

    - by Samuel Rossille
    I'm a complete newbie in system administration and I'm doing this as a hobby. I host my own git repository on a VPS. Let's say my user is john. I'm using the ssh protocol to access my git repository, so my url is something like ssh://[email protected]/path/to/git/myrepo/. Root is the owner of everything that's under /path/to/git I'm attempting to give read/write access to john to everything which is under /path/to/git/myrepo I've tried both chmod and setfacl to control access, but both fail the same way: they apply rights recursively (with the right options) to all the current existing subdirectories of /path/to/git/myrepo, but as soon as a new directory is created, my user can not write in the new directory. I know that there are hooks in git that would allow me to reapply the rights after each commit, but I'm starting to think that i'm going the wrong way because this seems too complicated for a very basic purpose. Q: How should I setup my right to give rw access to john to anything under /path/to/git/myrepo and make it resilient to tree structure change ? Q2: If I should take a step back change the general approach, please tell me.

  • Why does ganglia think my host is down?

    - by NZKoz
    I have ganglia set up to monitor our staging server, it's working great but I'm confused by the definition of 'down' to ganglia. There's a single node, running gmetad, gmond and the web frontend, but some small percentage of the time the web frontend shows some confusing output. Despite the fact that it's a single server in the cluster, and that server is the one serving the web interface, the dashboard output insists that the host is down. Then below that it has a graph which shows 50% down, 50% up. You can see an example of this here: http://i.imgur.com/MCWaS.jpg There's obviously something confusing ganglia somewhere, but I'm not sure where to start looking. Unfortunately googling for any combination of 'ganglia' 'down' 'metric name' seems return nothing but other people's ganglia installations displaying the same nonsense. Any tips on where to start looking would be greatly appreciated

  • With CentOS 6 and LXC, "ifconfig" is unable to see network interface (but busybox "ifconfig" works fine)

    - by larsks
    I've just started working with LXC under CentOS 6 (via the libvirt adapter). If I create an LXC container, I'm unable to see any network interfaces when using the native system tools: # ifconfig -a # The behavior is very odd; specifying an interface by names yields neither the expected output nor an error message. This is true even for clearly invalid interface names, like this: # ifconfig foo # The ip command exhibits the same behavior. On the other hand, if I use "ifconfig" provided by busybox, everything works as expected: # busybox ifconfig -a eth0 Link encap:Ethernet HWaddr 52:54:00:E0:12:C8 inet6 addr: fe80::5054:ff:fee0:12c8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:268 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:17814 (17.3 KiB) TX bytes:552 (552.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) So...what does busybox know that the native tools don't? The libvirt config for this environment is pretty standard; the network definition looks like this: <interface type='network'> <mac address='52:54:00:e0:12:c8'/> <source network='default'/> <target dev='veth0'/> </interface> The full configuration is here if you think it might help. I'm running: lxc-0.7.2-2.el6.x86_64 kernel-2.6.32-71.29.1.el6.x86_64 EDIT Weirder and weirder...it's a display issue, not a functionality issue. I can see the output of ifconfig if I pipe it into anything, so for example: # ifconfig eth0 | cat eth0 Link encap:Ethernet HWaddr 52:54:00:E0:12:C8 inet addr:192.168.10.10 Bcast:192.168.10.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fee0:12c8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:573 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:37914 (37.0 KiB) TX bytes:552 (552.0 b) And in fact even when not piping the output, strace shows that ifconfig is in fact writing the output to file descriptor 1 (aka stdout), so it's not clear why no output is actually showing up. This could be either an LXC or a virsh issue, I guess.

  • Extremely high mysqld CPU usage with no active queries

    - by RadarNyan
    I have a VPS running Ubuntu 12.04 LTS with LEMP stack, followed the guide from Linode Library (since I'm using a Linode) to setup, and everything worked fine until now. I don't know what's wrong, but my CPU usage just goes up since a week ago. Today things getting really bad - I got 74% CPU usage so I went check and found that mysqld taking too much CPU usage (somewhere around 30% ~ 80%) So I did some Google Search, tried disable InnoDB, restart mysql, reset ntp / system clock (Isn't this bug supposed to happen more than a year ago?!) and reboot my VPS, nothing helped. Even with mysql processlist empty, I still get mysqld CPU usage very high. I don't know what I missed and have totally no idea, any advice would be appreciated. Thanks in advance. Update: I got these from running "strace mysqld" write(2, "InnoDB: Unable to lock ./ibdata1"..., 44) = 44 write(2, "InnoDB: Check that you do not al"..., 115) = 115 select(0, NULL, NULL, NULL, {1, 0}^[[A^[[A) = 0 (Timeout) fcntl64(3, F_SETLK64, {type=F_WRLCK, whence=SEEK_SET, start=0, len=0}, 0xbfa496f8) = -1 EAGAIN (Resource temporarily unavailable) hum... I did tried to disable InnoDB and it didn't fix this problem. Any idea? Update2: # ps -e | grep mysqld 13099 ? 00:00:20 mysqld then use "strace -p 13099", the following lines appears repeatedly: fcntl64(12, F_GETFL) = 0x2 (flags O_RDWR) fcntl64(12, F_SETFL, O_RDWR|O_NONBLOCK) = 0 accept(12, {sa_family=AF_FILE, NULL}, [2]) = 14 fcntl64(12, F_SETFL, O_RDWR) = 0 getsockname(14, {sa_family=AF_FILE, path="/var/run/mysqld/mysqld.sock"}, [30]) = 0 fcntl64(14, F_SETFL, O_RDONLY) = 0 fcntl64(14, F_GETFL) = 0x2 (flags O_RDWR) setsockopt(14, SOL_SOCKET, SO_RCVTIMEO, "\36\0\0\0\0\0\0\0", 8) = 0 setsockopt(14, SOL_SOCKET, SO_SNDTIMEO, "<\0\0\0\0\0\0\0", 8) = 0 fcntl64(14, F_SETFL, O_RDWR|O_NONBLOCK) = 0 setsockopt(14, SOL_IP, IP_TOS, [8], 4) = -1 EOPNOTSUPP (Operation not supported) futex(0xb786a584, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0xb786a580, {FUTEX_OP_SET, 0, FUTEX_OP_CMP_GT, 1}) = 1 futex(0xb7869998, FUTEX_WAKE_PRIVATE, 1) = 1 poll([{fd=10, events=POLLIN}, {fd=12, events=POLLIN}], 2, -1) = 1 ([{fd=12, revents=POLLIN}]) er... now I totally don't get it x_x help

  • Resizing mysterious partition written by DDing an ISO file

    - by Jon
    I downloaded clonezilla and then wrote it to a USB flash drive with this: dd if=clonezilla.iso of=/dev/sdb I've confirmed that the system boots and clonezilla runs from the flash drive. I want to store a clonezilla backup on the same flash drive clonezilla is running on, but I tried it and ran out of space, so I started looking at how to resize the mysterious partition type that was generated from the ISO. fdisk -l /dev/sdb .... Device Boot Start End Blocks Id System /dev/sdb1 * 1 111 113664 17 Hidden HPFS/NTFS .... I've tried using ntfsresize from the Debian ntfsprogs package. I'm trying gparted next, but thought I'd ask here if anyone knows a neat way to resize a partition created on flash from a liveCD image. Thanks in advance Jon ps. Assume Debian 6 please.

  • Copying a large directory tree locally? cp or rsync?

    - by Rory
    I have to copy a large directory tree, about 1.8 TB. It's all local. Out of habit I'd use rsync, however I wonder if there's much point, and if I should rather use cp. I'm worried about permissions and uid/gid, since they have to be preserved in the clopy (I know rsync does this). As well as thinks like symlinks. The destination is empty, so I don't have to worry about conditionally updating some files. It's all local disk access, so I don't have to worry about ssh or network. The reason I'd be tempted away from rsync, is because rsync might do more than I need. rsync checksums files. I don't need that, and am concerned that it might take longer than cp. So what do you reckon, rsync or cp?

  • Getting rsync to move file from source to destination ?

    - by fabien-barbier
    Is rsync is a good choice for my project ? I have to : - copy files from source to destination folder via SSH, - be sure all files are copied, - delete source files after copy. - if I have conflict name, I have to rename files. It looks like I can use option : --remove-source-files (to delete source files) But how rsync manage conflict, can I had rules ? Use case on my project : I run scientific calculation on server A and results are inserted in folder "process", for each calculation I have a repository like this : /process/calc1. Now I would like to transfer repository "/calc1" to server B (I get /process/calc1), and delete "calc1" from server A. ...During another calculation I get "/process/calc2" on server A, the idea is also to move "calc2" in "/process/" directory on server B, then I have now on server B : - /process/calc1 - /process/calc2 (and /process/ on server A is empty). How rsync will manage conflict (on server B) if I have another folder like "/process/calc1" in server A after a new calculation (if "/process/calc1" already exist on server B) ? Is it possible to add rules with rsync, and rename "/process/calc1" by "process/calc1R2" in server B ? And so on (ex:calc1R3) ? Thanks.

  • NIC bonding with two uplinks

    - by Karolis T.
    Is bonding the preferred way of implementing ISP redundancy? In the texts I've seen, bond device has a netmask, gateway of it's own. How can this be obtained if there are two different gateways from two uplinks, which one to choose? Do I need any special routing rules to go with it or does simply configuring separate interfaces (using Debian, /etc/network/interfaces), i.e eth1, eth2 for their corresponding uplinks and bonding them to bond0 handle routing automatically? If I want to NAT client machines, do they use bond device's IP as a gateway? Does the bond0 device is the device that goes into iptables nat rules? Thanks

  • How hard for a Software Developer to Maintain a Server

    - by Samy
    I'm a software developer and don't have much experience as a sysadmin. I developed a web app and was considering buying a server and hosting the web app on it. Is this a huge undertaking for a web developer? What's the level of difficulty of maintaining a server and keeping up with the latest security patches and all that kind of fun stuff. I'm a single user, and not planning to sell the service to others. Can someone also recommend an OS for my case, and maybe some good learning resources that's concise and not too overwhelming.

  • Problems getting Cron to run processes tagged @reboot for LDAP users

    - by Ben Torell
    I have a lab of computers running Ubuntu 9.10. Most of the people who log on to these computers are users from an LDAP server, and not local users. We discovered that if an LDAP user has a crontab with an entry marked to be run @reboot, the command will not actually run upon the reboot of a machine. I'm pretty sure that this is because the cron daemon starts before networking is fully up, so the crontabs of any LDAP users aren't loaded and run or checked for @reboot. In fact, cron will ignore LDAP users' crontabs entirely after a reboot until that user runs crontab -e again and saves, or until the cron daemon is rebooted. We were able to fix one part of this problem by adding the following line to /etc/crontab: @reboot root /bin/sleep 45 && /etc/init.d/cron restart Thus, when cron starts back up upon a reboot, it waits for networking to get up, then restarts the cron daemon. That fixes the problem of crontabs not being read at all for LDAP users. However, since it's the cron daemon being restarted and not the computer, @reboot entries are ignored. Is there a way for a user to make a command run upon restarting the daemon, rather than a reboot? Or is there a better solution to this overall problem? Thanks.

  • Multiple interfaces to one IP address?

    - by Delan Azabani
    At present, I have: a Netgear router with DHCP off at 192.168.0.1 my computer eth0 at 192.168.0.2 wlan0 at 192.168.0.2 The wlan0 interface always connects to the router, while the eth0 interface connects to other computers with crossover and acts as a dnsmasq DHCP server for network boot and installation. If I use the Gnome NetworkManager to enable both connections, that is, with wlan0 connected to the router/internet and eth0 to another computer, both as 192.168.0.2, I cannot access the internet while eth0 is connected. Why is this? How can I configure my computer to follow wlan0 for Internet usage, but use eth0 for itself (the latter is working but blocking wlan0).

  • cannot print from flash-player plugin

    I am running flash-player plug-in 10.0.32.10 inside of Firefox on a SLED 11 machine. Firefox can print to the network printer without issue from File Print. However, I cannot get the flash-player plugin to print at all. The print dialog comes up, asks for which printer, and which pages. I click Print and it was as if I had pressed cancel. Is this a known issue?

  • Using Gentoo's `ebegin`, `eend` etc under Ubuntu

    - by Marcus Downing
    We're quite fond of the style of the ebegin, eend, eerror, eindent etc commands used by Portage and other tools on Gentoo. The green-yellow-red bullets and standard layout make for very quick spotting of errors, on what would otherwise be very grey command line output. #!/bin/sh source /etc/init.d/functions.sh ebegin "Copying data" rsync .... eend $? Producing output similar to: * Copying data... [ OK ] As a result we're using these commands in some of our common shell scripts, which is a problem for the people using Ubuntu and other linuxes. (linuces? linuxen? linucae? other distros) On Gentoo these functions are provided by OpenRC, and imported with functions.sh file (whose exact position seems to vary slightly). But is there a simple way of getting these commands on Ubuntu? In theory we could replace them all with dull echos, but we'd rather not?

  • Enable gzip on Nginx

    - by Rob Wilkerson
    Yes, I know that there are a lot of other questions that seem exactly like this out there. I think I must've looked all of them. Twice. In desparation, I'm adding another in case my specific configuration is the issue. Bear with me. First, the question: What do I need to do to get gzip compression to work? I have an Ubuntu 12.04 server installed running nginx 1.1.19. Nginx was installed with the following packages: nginx nginx-common nginx-full The http block of my nginx.conf looks like this: http { include /etc/nginx/mime.types; access_log /var/log/nginx/access.log; sendfile on; keepalive_timeout 65; tcp_nodelay on; gzip on; gzip_disable "msie6"; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } Both PageSpeed and YSlow are reporting that I need to enable compression. I can see that the request headers indicate Accept-Encoding:gzip,deflate,sdch, but the response headers do not have the corollary Content-Encoding header. I've tried various other config values (gzip_vary on, gzip_http_version 1.0, etc.), but no joy. As far as I know, I can only assume that nginx was compiled with compression support, but if there's any way to verify that, I'd love to know. If anyone sees anything I'm missing or can suggest further debugging, please let me know. I'm no sysadmin and I'm new to Nginx so I've exhausted everything I can think of or have read. Thanks.

  • Triple monitor setting in Linux with USB-HDMI adapter

    - by Oscar Carballal
    I'm trying to set up a triple monitor desktop at my office using Fedora 17, but it seems impossible, let me explain the setting: Laptop ASUS K53SD with 2 graphic cards, Intel and nVidia (Screen controled by Intel card) 24" Full HD monitor connected to the HDMI output (controlled by Intel card) 23" Full HD monitor connected to an USB-HDMI adapter (via framebuffer in /dev/fb2, apparently) VGA output (not used) controlled by nVidia card First of all, the USB-HDMI adapter works perfectly, it gives me a green screen (which means the communication is OK) and I can make it work if I set up a single monitor setting via framebuffer in Xorg. Here I leave the page where I got the instructions: http://plugable.com/2011/12/23/usb-graphics-and-linux Now I'm trying to set up the the two main monitors (laptop and 24") with the intel driver and the 23" with the framebuffer, but the most succesful configuration I get is the two main monitors working and the third disconnected.

  • Ubuntu 9.10 X Stuck in restart loop - I think...

    - by widgisoft
    Trying out Ubuntu, installation went fine - upgraded to the proprietary nVidia drivers but on restart I get a login prompt and the screen is flashing really fast almost as if Xserver is trying to start and failing, I can type when the screen isn't in a "flash" as it were and it's so fast and random it's hard to even type a login name without it missing some characters - this makes typing a password (i.e. not being able to see which characters made it or not) very hard. I can log back into the live cd and alter my settings - but I can't even find out how to stop X stop starting on boot; Looks like they've moved everything around :-p I'd like to: Stop X from crashing and going insane (if it is actually Xserver) Know how to stop X from starting on bootup, Looks like interactive boot is also off by default now Update: A temporary work around seems to be enabling ssh and just connecting to the box over the network - ssh seems to work fine :-p Cheers, Chris

  • iptables management tools for large scale environment

    - by womble
    The environment I'm operating in is a large-scale web hosting operation (several hundred servers under management, almost-all-public addressing, etc -- so anything that talks about managing ADSL links is unlikely to work well), and we're looking for something that will be comfortable managing both the core ruleset (around 12,000 entries in iptables at current count) plus the host-based rulesets we manage for customers. Our core router ruleset changes a few times a day, and the host-based rulesets would change maybe 50 times a month (across all the servers, so maybe one change per five servers per month). We're currently using filtergen (which is balls in general, and super-balls at our scale of operation), and I've used shorewall in the past at other jobs (which would be preferable to filtergen, but I figure there's got to be something out there that's better than that). The "musts" we've come up with for any replacement system are: Must generate a ruleset fairly quickly (a filtergen run on our ruleset takes 15-20 minutes; this is just insane) -- this is related to the next point: Must generate an iptables-restore style file and load that in one hit, not call iptables for every rule insert Must not take down the firewall for an extended period while the ruleset reloads (again, this is a consequence of the above point) Must support IPv6 (we aren't deploying anything new that isn't IPv6 compatible) Must be DFSG-free Must use plain-text configuration files (as we run everything through revision control, and using standard Unix text-manipulation tools are our SOP) Must support both RedHat and Debian (packaged preferred, but at the very least mustn't be overtly hostile to either distro's standards) Must support the ability to run arbitrary iptables commands to support features that aren't part of the system's "native language" Anything that doesn't meet all these criteria will not be considered. The following are our "nice to haves": Should support config file "fragments" (that is, you can drop a pile of files in a directory and say to the firewall "include everything in this directory in the ruleset"; we use configuration management extensively and would like to use this feature to provide service-specific rules automatically) Should support raw tables Should allow you to specify particular ICMP in both incoming packets and REJECT rules Should gracefully support hostnames that resolve to more than one IP address (we've been caught by this one a few times with filtergen; it's a rather royal pain in the butt) The more optional/weird iptables features that the tool supports (either natively or via existing or easily-writable plugins) the better. We use strange features of iptables now and then, and the more of those that "just work", the better for everyone.

  • pg_dump not working - do I need to change order of $PATH?

    - by A4J
    I'm trying to set the $PATH to pick up the latest version of pg_dump as I'm currently getting a mismatch error while doing a migrate in my Rails app (I recently changed the schema type to SQL). I have added a new file in /etc/profile.d called pg_dump.sh, and inside that put: PG_DUMP=/usr/pgsql-9.1 export PG_DUMP PATH=$PATH:$PG_DUMP/bin export PATH On looking at echo $PATH, I get: /usr/local/rvm/gems/ruby-1.9.3-p194/bin:/usr/local/rvm/gems/ruby-1.9.3-p194@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p194/bin:/usr/local/rvm/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/pgsql-9.1/bin:/root/bin And I still get the error. Do I need to change the order? If so any ideas how?
