• java memory allocation under linux

  - by pstanton

  I'm running 4 java processes with the following command: java -Xmx256m -jar ... and the system has 8Gb memory under fedora 12. however it is apparently going into swap. how can that be if 4 x 256m = 1Gb ? EDIT: also, how can all 8Gb of memory be used with so little memory allocated to basically the only thing running? is it java not garbage collecting because the OS tells it it doesn't need to or what?

• Linux find/search root partition ONLY?

  - by ~sd-imi

  Say I need to do: find / -name somefile.txt and say root partition / is mounted on /dev/sda5; however, let's say I also have 250GB partitions (/dev/sda6, /dev/sda7) mounted in /media - AND another location that I cannot currently remember. Say, also, that I know the file I'm looking for is on /dev/sda5. Obviously, the above command will also descend in /media and that other directory which represent the big partitions, wasting time in looking for the file in the wrong place. Is there a way to instruct find (or other command) to search only / on /dev/sda5, and NOT to descend to directories if they are on different partitions ? Thanks, Cheers!

• Linux: permission to read file from /sys/kernel/debug wihout root privileges

  - by gogowitczak

  I'd like to read small text file, located at: /sys/kernel/debug/vgaswitcheroo/switch without root permissions. It contains information about graphic cards (dedicated ATI Radeon and integrated Intel HD3000). I wrote a simple script displaying infomation I need, but it works only with root privileges. I already tried changing file & folder permissions, but when I restart my computer, the problem remains. Is it possible to permanently change that file permissions or owner?

• Google Chrome on Linux not using ALSA for sound

  - by DarkMoon

  On my laptop, I've got an .asoundrc file that outputs sound to my USB headset. This works fine for SMplayer and Firefox. However, Google Chrome (at least, Flash-based and HTML5-based videos and HTML5-based audio in Chrome) plays through the laptop speakers instead. I've tried running Chrome from a command-line, hoping there would be some helpful output, but no such luck. I've tried looking through Google for whether Chrome even uses ALSA, or if it uses something else, but I have been unsuccessful in this. This question seems to be the same issue, but no suggestion was made. Anyone have any ideas? I'm running Gentoo with a 3.10.17 kernel, 1.0.27 ALSA utils, 2.6.5 FVWM, and 36.0.1985.143 Chrome. If you need more info, please let me know. EDIT: I've configured the USB headset as the default ALSA device. Volume levels for both headset and onboard are set and un-muted using alsamixer. My .asoundrc file is as follows. ctl.!default { type hw card Headset } pcm.dmixer { type dmix ipc_key 1024 slave { pcm { type hw card Headset } period_size 1024 buffer_size 4096 } bindings { 0 0 1 1 } } pcm.!default { type plug slave.pcm dmixer }

• Graphing per-user CPU usage on a Linux machine

  - by mart1n

  I want to graph (graphical output would be great, i.e. a .png file) the following situation: I have users A, B, and C. I limit their resources so that when all users run a CPU intensive task at the same time, those processes will use 25%, 25%, and 50% of CPU. I know I can get the real-time stats using top but have no idea what to do with them. I've searched through the huge top man page but haven't found much on the subject of outputting data that can be graphed. Ideally, the graph would show a span of maybe 30 seconds. Any ideas how to achieve this?

• Load-balanced Linux server across internet?

  - by LinuxGnut

  I'm investigating setting up a load balanced server solution consisting of three CentOS 5.4 boxes. Two of these boxes will reside in one facility, while a third will reside in a different facility. I'm currently working to set up heartbeat, ldirectord, ipvsadm to load-balance the machines, but I'm not sure its going to work with I'm not overly familiar with the details behind how all of these work, but is the load balancing going to work correctly when these servers are not all on the same LAN? I'm not sure if heartbeat is using SNMP to send signals or not, which would only work over a LAN. Has anyone tried this or found a different solution?

• Linux command line based spam checker?

  - by anonymous-one

  Does a command line based spam checker exist? We have created a mailbox at a 3rd party, and unfortunately decided on spam checking 'disabled' in the initial setup. There is no way to re-enable spam checking, the mailbox must be delete (and thus all contents lost) and re-created. Does anything exist where we can pump in either: A) Subject + from + to + body + all other fields. OR B) Raw message dump (headers + body). And the command line will let us know weather the email is possibly spam? Thanks.

• Ubuntu server 10.04 disconnects after short periods of inactivity on my site

  - by user57019

  I'm new to Ubuntu (installed it for the first time just a couple of days ago on my server). I've Ubuntu Server 10.04 and am just using the terminal, no GUI like Gnome. So far it's working pretty great except for one big thing. Whenever I go to sleep and there's no activity on my server (it's not a big site so active users drop to 0 during the night), the server kind of disconnects. The only thing that can bring the site back online is to restart the whole server. I've tried disabling powersaving by using setterm but that changes nothing. Even if I wake up the server by pressing any key or so the site wont go back online! I've tried just restarting both Apache and MySQL (I'm using LAMP-server btw) but not even that works. But as soon as I turn the power off and on at the server, everythings work like normal for a couple of minutes of inactivity (~5-15 minutes I'd guess) and then it's down again unless someone logs in to the site and is active. I was previously using XAMPP on my laptop with Windows XP and that worked 24/7 so I don't think it's anything with my router or ISP. This is driving me crazy! My site is down all the time I'm in school as I have no possibility to restart the server if it becomes offline. Does anyone have a clue to what could be wrong?

• Failed Software RAID0 on Linux - Attempting to recover data

  - by Gizmo_the_Great

  I have a two disk RAID0 software raid (not hardware raid) that is reported to have failed during boot and my OS won't start.

• Xamp on ubuntu serves php source for root url only

  - by mazaryk

  Hey, Okay, so installed xamp on my ubuntu machine, started it up and everything worked. Apache ran my php app just fine (including requests to the root url "/"). However, after the first reboot since installing, when I request "http://localhost/" apache serves up the index php page as a phtml source file. All other urls (like "http://localhost/login") work as expected. Backgound: The only modification I made to xamp was to setup a vhost for my app. The app uses an .htaccess file where I define some rewrite rules (the app is an MVC framework and all urls are rewritten to a single entry point php file). I'm using Xamp because I need php = 5.3.0. I know apache will serve up the source of a php file when it doesn't know to process php files. But the config does indeed have "AddType application/x-httpd-php .php" and as I said, the app works for all urls except the root "/" (and only since I've rebooted). The .htaccess file does contain a DirectoryIndex directive. xamp 1.3.7a Ubuntu 9.10 Any ideas?

• source command in Linux

  - by Rodnower

  My question is: why if I run some file with name aliases for example with content such as: alias lsa="ls -a" directly: $ ./aliases it don't create the alias (may be only in script context). But if I run it with command "source": $ source aliases it do the work? I mean after execution the alias "lsa" existing in context of command shell? "man source" give: "No manual entry for source", and in google I just found that it runs Tcl, but why Tcl influence shell context and bush not?

• ubuntu 12.04 kvm virtual server network setup, can't get the machine to be connectable

  - by xyious

  I have worked on my Ubuntu Server host for weeks now and I just can not manage to get the virtual machines into the network.... here's what I need to do: I need to be able to create virtual machines that have IP addresses that can be reached from the outside (192.168 network). I need to be able to connect to the virtual machines through ssh, ftp, http and preferably https, anything else doesn't matter that much. So far everything seems simple enough and I have a lot of leeway in terms of IP address range and server/client configuration. I have the option of taking part of a /24 net as most IPs aren't used, and if it's absolutely necessary I have the option of creating a new /24 subnet. Also have the option of reformatting and reinstalling OS on the host and recreating the virtual machines as nothing has been done other than trying to get virtual machines to work. I would prefer if the virtual machines were just part of the normal network which would be 192.168.5.0/24. The host machine has 2 network cards so I don't even necessarily need the Host to be connectable in the same /24 network. I have tried (I think) just about everything from about 5 different tutorials on bridging (giving br0 the same IP that eth0 used to have (Host is able to connect to VM and vice versa, VM doesn't have outside network access), having eth0 set up like it always was and having br0 have a different IP (same as above), NAT with port forwarding (which I would have preferred not to use but will if it works), turning off one of the hosts network cards and just using one of them, different subnets.... etc. I do know my way around iptables fairly well.... Host is 64bit Ubuntu Server 12.04, using libvirt/kvm. edits: Local network is 192.168.5.0/24, host has static ip 192.168.5.254, GW .5.1 which is also nameserver. We have a second Local network at 192.168.10.0/24 with .10.1 GW, but both hosts and VMs were supposed to go into the .5 subnet. The .10 subnet isn't required, but it wouldn't be horrible if the Host were only accessible in the .10 subnet.

• restrict directory listing linux

• Monitoring disk block access in Linux

  - by VoidPointer

  Is there a way to gather statistics about blocks being accessed on a disk? I have a scenario where a task is both memory and I/O intensive and I need to find a good balance as to how much of the available RAM I can assign to the process and how much I should leave for the system for building its I/O cache for the block device being used. I suspect that most of the I/O that is currently happening is accessing a rather small subset of the device and that performance could be optimized by increasing the RAM that is available for I/O buffering. Ideally, I would be able to create something like a "heat-map" that shows me which parts of the disk are accessed most of the time.

• Linux: Three default gateways?

  - by Daniel

  My server has three default gateways, how can that be? Shouldn't there be one default gw? I have three NICs, each attached to a separate subnet: server1:~# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.5.0.0 * 255.255.255.224 U 0 0 0 eth3 localnet * 255.255.255.224 U 0 0 0 eth0 192.168.8.0 * 255.255.255.192 U 0 0 0 eth1 default 10.5.0.1 0.0.0.0 UG 0 0 0 eth3 default 192.168.8.1 0.0.0.0 UG 0 0 0 eth1 default 10.1.0.1 0.0.0.0 UG 0 0 0 eth0 Sometimes, I can't ping a host on the Internet, sometimes I can. What I want is traffic to the Internet (0.0.0.0) routed through a specific NIC. Can I just add a route for 0.0.0.0 and default gw to one of the eth0-3 interfaces? Will it break my connection? I'm using Debian, here is my /etc/network/interfaces: # This file describes the network interfaces available on your system # and how to activate them.

• Linux, PHP, and mysqlnd?

  - by bob-the-destroyer

  Looks like most common distros build their PHP packages without mysqlnd, instead relying on the old libmysql library. Are there any distros that do include the new mysql native driver even as an option in any of their officially supported repositories? If not, is it possible (and if so, how) to rebuild these three (mysql, mysqli, & pdo_mysql) extensions without having to rebuild the entire PHP install? In my case, there are several PHP functions I need that are available only if these Mysql extenstions are built against mysqlnd. So I'd be fine installing a new OS to get these if the OS offers and supports it.

• Man pages in Linux

  - by Ayos

  I don't seem to have all the man pages that I need. For example, my college computers (running Fedora 14) have man pages for ASCII, all the standard C libraries (stdlib.h, stdio.h) and so on and so forth. I wish to "install" these pages, after looking up on the Internet I couldn't really find anything that made sense. How can I get, say, the man-page of ASCII (I know it's not really a command or a daemon or anything like that, but typing man ASCII on the college computer gets me a page with the ASCII value table + a little more information). I don't want to keep using the Internet for looking up man pages every time I need to look up a function, function prototype or the ASCII table or something like that.

• linux static ip problem

  I have a serve running centOS and I'd like to have the following setup: The server needs to have a static ip and be accessible by name. What I want is independently of the network being able to connect the server to the network and access it by name on Firefox as it will be running a web page. I tried setting the ip manually but while the inet addr is set as I want it the Bcast isn't. And I only can ping the server on the Bcast ip and because it is 192.168.2.255 ssh says it's not valid.

• How to autostart service in ANY linux?

  - by user329115

  I need to install the dumbest possible service (a binary) and have it reliably run as the current user at boot (or login, whatever) at as many platforms as possible (of the aging point-of-sale type). The app monitors another archives generated by another app in the user-session. Startup alternatives considered: init.d @reboot in crontab a .desktop file in ~/.config/autostart a myriad of other solutions including .profile and .bashrc All of the above break down at some point. The problems stem from not wanting to run as root (I want the files generated to be user-accessible), and not having a way to reliably get the current user name in sudo on all platforms. Ideally not even sudo can be assumed available. Hey, I just want to run something on boot and I have "root" power to do so. Windows get the job done easily enough. This isn't rocket science, is it?

• Strange 3-second tcp connection latencies (Linux, HTTP)

  - by user25417

  Our webservers with static content are experiencing strange 3 second latencies occasionally. Typically, an ApacheBench run ( 10000 requests, concurrency 1 or 40, no difference, but keepalive off) looks like this: Connection Times (ms) min mean[+/-sd] median max Connect: 2 10 152.8 3 3015 Processing: 2 8 34.7 3 663 Waiting: 2 8 34.7 3 663 Total: 4 19 157.2 6 3222 Percentage of the requests served within a certain time (ms) 50% 6 66% 7 75% 7 80% 7 90% 9 95% 11 98% 223 99% 225 100% 3222 (longest request) I have tried many things: - Apache2 2.2.9 with worker or prefork MPM, no difference (with KeepAliveTimeout 10-15) - Nginx 0.6.32 - various tcp parameters (net.core.somaxconn=3000, net.ipv4.tcp_sack=0, net.ipv4.tcp_dsack=0) - putting the files/DocumentRoot on tmpfs - shorewall on or off (i.e. empty iptables or not) - AllowOverride None is on for /, so no .htaccess checks (verified with strace) - the problem persists whether the webservers are accessed directly or through a Foundry load balancer Kernel is 2.6.32 (Debian Lenny backports), but it occurred with 2.6.26 also. IPv6 is enabled, but not used. Does the issue look familiar to anyone? Help/suggestions are much appreciated. It sounds a bit like a SYN,ACK packet getting lost or ignored.

• Walk me through the Linux log files (please)

  - by Andy

  Hey all, I just tried loading a 2MB file in gedit and it silently died on me. I was wondering if anything might appear in a log file that might help me diagnose this: I checked syslog and found out it segfaulted. While doing this I realised that I don't really know anything about how logging is organised on *nix machines. All I know at the mo is Logs are typically stored in /var/log/... is there anywhere else that I should know about? I'm familiar with application specific logs, such as apache's. I understand that dmesg is the bootup log, and syslog is a general system log... is that right? So would someone mind taking me through the most useful logs? Are the two logs I mention in the final point the only general logs? And what are the funky numbers at the start of lines in dmesg? Seconds since startup? Please include anything in your answers that you think would improve my understanding here and help me track down anomalies! TIA Andy

• Ubuntu server 10.04 disconnects after short periods of inactivity on my site

  - by Melot

  Hi! I'm new to Ubuntu (installed it for the first time just a couple of days ago on my server). I've Ubuntu Server 10.04 and am just using the terminal, no GUI like Gnome. So far it's working pretty great except for one big thing. Whenever I go to sleep and there's no activity on my server (it's not a big site so active users drop to 0 during the night), the server kind of disconnects. The only thing that can bring the site back online is to restart the whole server. I've tried disabling powersaving by using setterm but that changes nothing. Even if I wake up the server by pressing any key or so the site wont go back online! I've tried just restarting both Apache and MySQL (I'm using LAMP-server btw) but not even that works. But as soon as I turn the power off and on at the server, everythings work like normal for a couple of minutes of inactivity (~5-15 minutes I'd guess) and then it's down again unless someone logs in to the site and is active. I was previously using XAMPP on my laptop with Windows XP and that worked 24/7 so I don't think it's anything with my router or ISP. This is driving me crazy! My site is down all the time I'm in school as I have no possibility to restart the server if it becomes offline. Does anyone have a clue to what could be wrong?
