  • NFS Issues in Gnome

    - by Alex
    I mount NFSv4 export via /etc/fstab and mount and use the shared folder in nautilus. There are two issues: When I copy a large file (around 4 GB) to the NFS server, the progress bar rapidly goes to 2 GB and then basically stops moving. But the copy s still in progress - it is just not displayed well When I disconnect from the network without unmounting the nfs share, nautilus freezes. How can I work around that? /etc/export on the server /export/share 192.168.0.0/24(rw,sync,insecure,no_subtree_check,anonuid=1000,anongid=1000) /etc/fstab on the client: server:/share /mnt nfs4 soft,tcp

  • impossible to connect.. days trying..

    - by dany
    I have a problem: I am on Debian. I configured my nic with a static ip (192.168.1.56). When I try to connect to a network, initially with ifconfig eth2 I get (correctly): eth2 inet addr:192.168.1.56 .... inet6 addr: fe80:221:ff:fe96:4598/64 but after a few seconds the 102.168.1.56 disappears and after some other seconds disappears the inet6 address too. When I press in the nm-applet it requires me the password but in the meantime it try to connect. At uni, the connection is a DHCP one. It works for the first few seconds but after it doesn't. Any possible solution? Here it is the relevant part of the syslog: (static ip configuration) http://pastebin.com/u3BPAsda

  • Apache 2.4 with PHP-FPM

    - by tubaguy50035
    I'm trying to setup Apache 2.4 with PHP-FPM 5.4 using the new modules with Apache 2.4. The following is what I have currently in my virtual host file: <VirtualHost *:80> ServerAdmin root@localhost DocumentRoot /var/www #Directory permissions <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Require all granted </Directory> CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> I have PHP-FPM running using Unix sockets with a sock file located at /var/run/php5-fpm.sock. How do I proxy my requests to this sock file? I've seen some sites say to use ProxyPassMatch and others are saying Rewrite Rule. Are there pros or cons on either side? Also, most sites I'm seeing are showing ProxyPassMatch with a regex to only pass .php files. Could I also send it .html files? For whatever reason, we have a ton of PHP inside .html files. Edit: As noted in the comments, it looks like mod_proxy_fcgi doesn't support Unix sockets. Is there another module I should be using?

  • Logging upload attempt with proftpd

    - by Amit Sonnenschein
    I have a logging server that i use with external hardware, the idea is that a special hardware is uploading logs about it's operation every few hours and from the server i can do whatever i need to do with the information, the old server was getting a bit too old and i've moved to a new one, i've install lamp,proftpd and ssh (just the same as i had on the old server). now for some reason the logs are not being uploaded and i don't know why. the hardware uses a direct ftp access - i've the proftpd.log and saw that the connection is not being rejected (just to make sure i didn't make a mistake with the user/pass) my problem is that for some reason the upload itself is failing... it might be due to wrong path (as it's hard coded in the hardware) but i can't really know as proftpd wont give me any details.. i've tried to change the loglevel to "debug" thinking it would give me more information but i don't see any change... is there any other way i can make sure proftpd logs EVERTHING ?

  • Linux boot - stop the kernel switching to a new framebuffer mode clearing output

    - by Avio
    I'm working on an embedded system (based onUbuntu 12.04 LTS) and I'm customizing its kernel. I'm having some problem with upstart, mountall and plymouth. Nothing unsolvable I suppose, but the real problem is that I can't diagnose properly what's going on because the kernel (or maybe plymouth) changes the video mode in the middle of the boot process. This completely wipes entire lines of log and prevents any debugging of kernel misconfigurations. My Grub2 config seems to be ok with: GRUB_CMDLINE_LINUX="" GRUB_CMDLINE_LINUX_DEFAULT="acpi=force noplymouth" GRUB_GFXMODE=1024x768x32 GRUB_GFXPAYLOAD_LINUX=keep Here is some relevant output of lspci: 00:00.0 Host bridge: Intel Corporation Mobile 945GSE Express Memory Controller Hub (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GSE Express Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) And here is the relevant portion of my kernel configuration: CONFIG_AGP=y CONFIG_AGP_INTEL=y CONFIG_VGA_ARB=y CONFIG_VGA_ARB_MAX_GPUS=16 CONFIG_DRM=y CONFIG_DRM_KMS_HELPER=y CONFIG_DRM_I915=y CONFIG_DRM_I915_KMS=y CONFIG_VIDEO_OUTPUT_CONTROL=y CONFIG_FB=y CONFIG_FB_BOOT_VESA_SUPPORT=y CONFIG_FB_CFB_FILLRECT=y CONFIG_FB_CFB_COPYAREA=y CONFIG_FB_CFB_IMAGEBLIT=y CONFIG_FB_MODE_HELPERS=y CONFIG_FB_VESA=y CONFIG_BACKLIGHT_LCD_SUPPORT=y CONFIG_BACKLIGHT_CLASS_DEVICE=y CONFIG_VGA_CONSOLE=y CONFIG_VGACON_SOFT_SCROLLBACK=y CONFIG_VGACON_SOFT_SCROLLBACK_SIZE=640 CONFIG_DUMMY_CONSOLE=y CONFIG_FRAMEBUFFER_CONSOLE=y CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y CONFIG_FONT_8x8=y CONFIG_FONT_8x16=y CONFIG_LOGO=y CONFIG_LOGO_LINUX_MONO=y CONFIG_LOGO_LINUX_VGA16=y CONFIG_LOGO_LINUX_CLUT224=y Every other custom/stock kernel boot fine with that Grub2 config. What I would like to have is a single flow of messages on a single console (retaining one screen resolution) from the bootup logo till the login prompt. Does anybody know what I have to tweak to achieve this?

  • Excessive denied requests for port 58322 in syslog

    - by Nathan C.
    My iptables is setup to block all unneeded ports as it should but I'm checking my syslog due to these random but all-to-frequent apache2 crashes and I noticed a lot of requests such as this.

Here's a rule (broken down for readability): ACTION=="add", SUBSYSTEM=="usb", ATTR{busnum}=="1", ATTR{devpath}=="2", ATTR{idVendor}=="05e1", NAME="video97" It works. /dev/video97 is created But the original /dev/video1 node is STILL there. The even worse, when I try to view the /dev/video97 node in guvcview it doesn't work, while the original node DOES work.

  • Good set of web hosting permissions?

    - by Jorge Israel Peña
    Hey guys, I just got a linode and I'm in the process of configuring it. It's running nginx with php-fpm and passenger. nginx was compiled and is running as user nginx. php-fpm (php with fastcgi process manager) is running as www-data (in group www-data). My sites are currently in /var/www, so for example /var/www/test.com I'm just wondering what the general 'flow' of things is. So for example, /var/www is owned by root, should I chown of /var/www/test.com to nginx or www-data? Or should I put nginx in the www-data group? How should site uploading work, I just transfer files to the /var/www/test.com directory as root (sudo) and then chown -R www-data:www-data .? Thanks. I'm capable of figuring things out on my own, I'm just wondering what the typical/general way of handling users/groups/permissions/site-files is on linux with a webserver.

  • VMware postfix server drops connection

    - by nicoX
    Our physical server godzilla forwards mails to our virtuall VMware server b4. They are on the same net. Often connection drops, we can't ping godzilla with our b4. That means mails from godzilla won't reach b4 and the mails will be in handed into the mailq. Sometimes it takes some hours and the issue will auto fix itself, b4 will wake up and the mail will be delivered. Another thing if we remotely ssh into the b4, the b4 will wake up and and receive any mailq mails from godzilla and deliver them. netadmin@b4:/var/log$ arp -a ?

  • Why is my display name in Ubuntu Software Center some weird set of letters?

    - by Ike
    In USC, after I submit a review, my display name is "Bnxdcty"... a swell name, but where did it come from? I have checked the ubuntu single sign on page, verified my nickname on there, changed it to something else and back again for good measure, but still my reviewer name is somehow still "Bnxdcty". I even unauthorized ubuntu software center and then re-opened it/authorized it to my account. Does this just appear as this to me and others see my correct user nickname? It doesn't bother as much as it confuses me. I just know it will be something stupid that everyone knows but me.

  • pdns-recursor allocates resources to non-existing queries

    - by azzid
    I've got a lab-server running pdns-recursor. I set it up to experiment with rate limiting, so it has been resolving requests openly from the whole internet for weeks. My idea was that sooner or later it would get abused, giving me a real user case to experiment with. To keep track of the usage I set up nagios to monitor the number of concurrent-queries to the server. Today I got notice from nagios that my specified limit had been reached. I logged in to start trimming away the malicious questions I was expecting, however, when I started looking at it I couldn't see the expected traffic. What I found is that even though I have over 20 concurrent-queries registered by the server I see no requests in the logs. The following command describes the situation well: $ sudo rec_control get concurrent-queries; sudo rec_control top-remotes 22 Over last 0 queries: How can there be 22 concurrent-queries when the server has 0 queries registered? EDIT: Figured it out! To get top-remotes working I needed to set ################################# # remotes-ringbuffer-entries maximum number of packets to store statistics for # remotes-ringbuffer-entries=100000 It defaults to 0 storing no information to base top-remotes statistics on.

  • ffmpeg: video file played OK on Ubuntu, but no sound on XP

    - by Andy Le
    I created a video clip using ffmpeg (vcodec: mpeg2video, acodec: AC3 5.1). The file can be played normally on Ubuntu, but when I play it on an XP machine, there is no sound. I can play AC3 files and other movies with AC3 sound. I already tried many codec packs and many players. When I compare the MediaInfo tab of the Properties window of the file with another playable movie, I see that the Audio Identifier of the audio stream in my file is 0x80 while it is 0x02 in the other movie. So I guess that's why players on XP can't recognize the audio codec. When I use an MKV container instead of MPEG (still mpeg2video codec), then the result is OK on both Ubuntu and XP (with the correct Audio ID). I really need MPEG though. Any idea? This is the command I used: ~/ffmpeg/ffmpeg/ffmpeg -loop_input \ -t 97 -r 30000/1001 -i v%4d.tga -i final.ac3 \ -vcodec mpeg2video -qscale 1 -s 400x400 -r 30000/1001 \ -acodec copy -y out6.mpeg 2 This is the output of mediainfo (on Ubuntu): General Complete name : out6.mpeg Format : MPEG-PS File size : 6.86 MiB Duration : 1mn 37s Overall bit rate : 593 Kbps Video ID : 224 (0xE0) Format : MPEG Video Format version : Version 2 Format profile : Main@Main Format settings, BVOP : No Format settings, Matrix : Default Format_Settings_GOP : M=1, N=12 Duration : 1mn 37s Bit rate mode : Variable Bit rate : 122 Kbps Width : 400 pixels Height : 400 pixels Display aspect ratio : 1.000 Frame rate : 29.970 fps Resolution : 8 bits Colorimetry : 4:2:0 Scan type : Progressive Bits/(Pixel*Frame) : 0.025 Stream size : 1.41 MiB (21%) Audio ID : 128 (0x80) Format : AC-3 Format/Info : Audio Coding 3 Duration : 1mn 36s Bit rate mode : Constant Bit rate : 448 Kbps Channel(s) : 6 channels Channel positions : Front: L C R, Side: L R, LFE Sampling rate : 44.1 KHz Stream size : 5.18 MiB (75%)

  • Strange ssh key issue

    - by user55714
    Scenario 1. I am doing this from /home/deploy directory I am trying to set up ssh with github for capistrano deployment. this has been an absolute nightmare. when I do ssh [email protected] as the deploy account I get Permission denied (publickey). so may be the key is not being found, so If I do a ssh-add /home/deploy/.ssh/id_rsa Could not open a connection to your authentication agent. (i did verify that the ssh-agent was running) If I do exec ssh-agent bash and then repeat the ssh-add then the key does get added and I can ssh into github. Now I exit from the ssh connection to my server and ssh back in and I can't ssh into github anymore! Scenario 2 if I login to my remote server and then cd into my .ssh directory and ssh into github then it all works fine I guess there is a problem with locating the key and for some reason the agent isn't funcitoning correctly. Any ideas? Her is a pastie with more details..my .bashrc, permissions etc. http://pastie.org/pastes/1190557/

  • What actions does Ubuntu trigger when battery is low?

    - by blueyed
    When the battery is low, the screen gets dimmed after a few seconds already. This appears to be some special power-saving mode, and might be related to the time in org.gnome.settings-daemon.plugins.power.time-low (1200 seconds (20 minutes) the default). While this seems to get triggered by gnome-settings-daemon, I wonder what else Ubuntu does when this happens (e.g. via DBus listeners), or other event listeners that look for a "low battery" state. It seems like something in this regard causes Ubuntu / X / the system to behave more sluggish afterwards (when the laptop is on AC again), and I would like to look into what might be causing this. I could not find anything related via dconf-editor, e.g. in org.gnome.settings-daemon.plugins.power. It appears to get setup via idle_configure in plugins/power/gsd-power-manager.c, but it's probably something more related to something that listens on the DBus interface, which gets notified via e.g.: if (!g_dbus_connection_emit_signal (manager->priv->connection, NULL, GSD_POWER_DBUS_PATH, "org.freedesktop.DBus.Properties", "PropertiesChanged", props_changed, &error)) I could imagine that some "power saving" property gets set, but not unset when AC is available anymore and/or the battery is not low anymore. I have looked at the CPU governor setting (/sys/devices/system/cpu/cpu*/cpufreq/scaling_governor), but it was ondemand. I am using gnome-settings-daemon with awesomeWM on Ubuntu 14.04. gnome-settings-daemon=3.8.6.1-0ubuntu11.1 I've also compared gsd's plugins/power/gsd-power-manager.c with the one from Debian's gnome-settings-daemon-3.12.1, but could not find anything obvious that might have been fixed/changed in this regard. I have managed to trigger the gnome-power-manager's gnome-settings plugin (which dims the screen etc), by patching upower and use it after killing the system's upower daemon. (note that it's probably only energy that is being used by gpm to calculate it by itself). It does not make the system become sluggish.. OTOH I have not heard the speaker's beeping, which might come from the BIOS, which might be involved here, too - or other programs using the kernel's interface on /sys/class/power_supply/BAT0/. --- src/linux/up-device-supply.c.orig 2014-06-07 16:48:32.735920661 +0200 +++ src/linux/up-device-supply.c 2014-06-07 16:48:39.391920525 +0200 @@ -821,6 +821,9 @@ supply->priv->energy_old_first = 0; } + percentage = 3.1f; + time_to_empty = 3*60; + energy = 5; g_object_set (device, "energy", energy, "energy-full", energy_full,

  • Grub error 18, gparted not showing anything

    - by Montecristo
    Some week ago I started having some problems with my pc, sometimes it just freezed not allowing me to do anything. I had to turn it off and on and sometimes do it a couple of time even at startup. Now it does not start at all, grub is giving me error 18. I have found that a solution is to create a bootable partition in the first sector of the disk. gparted does not recognize any partition, the window in which there would be my partitions is empty. sudo fdisk -l does not output anything. If I type sudo mount /dev/sda and then tab tab to autocomplete these are the devices coming out: sda sda1 sda2 sda5. If I launch sudo mount -t ext3 /dev/sda1 disk I get the following error: mount: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg outputs [ 1831.974847] EXT3-fs: unable to read superblock Do you know how to solve this issue? I'm not completely sure this is a software problem, should I try with a new hard disk?

  • how to install/compile CORSIKA/FLUKA for Ubuntu x32 12.04?

    - by Pantea Davoudifar
    I want to use some programs (CORSIKA/FLUKA) which are essentially designed for 32 bit systems. so I installed Ubuntu 12.04 32 bit on my system (Intel® Core™ i7-2700K CPU @ 3.50GHz × 8). Before this I had installed Ubuntu 9.10 (32-bit) on an older system and installed g77 from hardy repositories, compiled those programs without any problem. But this time when changing the repositories, g77 could not be installed even i removed all the things that i thought make this installation impossible, for example I need gcc-3.4 and removed all newer versions and tried to install them from hardy repositories. but the problem is that, whenever I have g77, corsika does not compile, and whenever I remove it, fluka does not compile, and also i received a error messages like this: crt1.o not found in /usr/bin/lb. In fact these .o files does not exist on my system user/bin/lb I have no directory lb there? I do not know how to link it? Or do i need to reinstall everything?
