  • How do I set image position in conky

    - by realitygenerator
    I copied and modified an existing .conkyrc file from the ubuntu forum and I'm trying to place the LinuxMint logo in a specific position Below are my conkyrc file and the screenshot # UBUNTU-CONKY # A comprehensive conky script, configured for use on # Ubuntu / Debian Gnome, without the need for any external scripts. # # Based on conky-jc and the default .conkyrc. # INCLUDES: # - tail of /var/log/messages # - netstat shows number of connections from your computer and application/PID making it.

  • Help writing server script to ban IP's from a list

    - by Chev_603
    I have a VPS that I use as an openvpn and web server. For some reason, my apache log files are filled with thousands of these hack attempts: "POST /xmlrpc.php HTTP/1.0" 404 395 These attack attempts fill up 90% of my logs. I think it's a WordPress vulnerability they're looking for. Obviously they are not successful (I don't even have Wordpress on my server), but it's annoying and probably resource consuming as well. I am trying to write a bash script that will do the following: Search the apache logs and grab the offending IP's (even if they try it once), Sort them into a list with each unique IP on a seperate line, And then block them using the IP table rules. I am a bash newb, and so far my script does everything except Step 3. I can manually block the IP's, but that's tedious and besides, this is Linux and it's perfectly capable of doing it for me. I also want the script to be customizable so that I (or anyone else who wants to use it) can change the variables to suit whatever situation I/they may deal with in the future. Here is the script so far: #!/bin/bash ##IP LIST GENERATOR ##Author Chev Young ##Script to search Apache logs and list IP's based on custom filters ## ##Define our variables: DIRECT=~/Script ##Location of script&where to put results/temp files LOGFILE=/var/log/apache2/access.log ## Logfile to search for offenders TEMPLIST=xml_temp ## Temporary file name IP_LIST=ipstoban ## Name of results file FILTER1=xmlrpc ## What are we looking for? (Requests we want to ban) cd $DIRECT if [ ! -f $TEMPLIST ];then touch $TEMPLIST ##Create temp file fi cat $LOGFILE | grep $FILTER1 >> $DIRECT/$TEMPLIST ## Only interested in the IP's, so: sed -e 's/\([0-9]\+\.[0-9]\+\.[0-9]\+\.[0-9]\+\).*$/\1/' -e t -e d $DIRECT/$TEMPLIST | sort | uniq > $DIRECT/$IP_LIST rm $TEMPLIST ## Clean temp file echo "Done. Results located at $DIRECT/$IP_LIST" So I need help with the next part of the script, which should ban the IP's (incoming and perhaps outgoing too) from the resulting $IP_LIST file. I don't care if it utilizes UFW or IPTables directly, as long as it bans the IP's. I'd probably run it as a cron task. What I'm having trouble with is understanding how to use line of the result file as a seperate variable to do something like: ufw deny $IP1 $IP2 $IP3, ect Any ideas? Thanks.

  • What kind of “sysadmin stuff” should I show to students during a talk?

    - by Gregory Eric Sanderaon
    A teacher asked me If I could talk about my job as a linux sysadmin in his class. The course is called "Introduction to Operating systems" and i've been given 45 minutes to talk. The students are beginning their second year, so they've had a bit of experience with programming in different languages. What i'm like to do is show a series of hands-on examples of the kinds of things I do on a regular basis. I've already got a few ideas jotted down, but I'm afraid that they might be either too advanced or too simple for the students to appreciate. Another concern is that a topic might be too long to explain and use too much time overall. Here are a few ideas : Program deployment using version control (git in my case) filtering apache logs using grep, awk, uniq, tail A couple of bash scripts that i've made for various stuff on servers live montitoring (htop, iotop, iptraf) creating databases and assigning roles in mysql/postgresql So, are these ideas any good ? Do you have better ideas ? are the ideas too simple and should I go for more "advanced" stuff ?

  • Slow transfer speed between two servers

    - by Linux Guy
    I have two servers both network cards speed is 10Gbps The inbound bandwidth between two servers is 10Gbps , the outbound bandwidth internet bandwidth is 500Mpbs Both servers using public ip addresses in public and private network Both servers transfer and connection on nginx port , and the server B used for streaming media , like youtube stream videos I check the transfer speed using iperf utility From Server A to Server B # iperf -c 0.0.0.1 -p 8777 ------------------------------------------------------------ Client connecting to 0.0.0.1, TCP port 8777 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ 3] local 0.0.0.0 port 38895 connected with 0.0.0.1 port 8777 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.8 sec 528 KBytes 399 Kbits/sec My Current Connections in Server B # netstat -an|grep ":8777"|awk '/tcp/ {print $6}'|sort -nr| uniq -c 2072 TIME_WAIT 28 SYN_RECV 1 LISTEN 189 LAST_ACK 139 FIN_WAIT2 373 FIN_WAIT1 3381 ESTABLISHED 34 CLOSING Server A Network Card Information Settings for eth0: Supported ports: [ TP ] Supported link modes: 100baseT/Full 1000baseT/Full 10000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 10000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: external Auto-negotiation: on MDI-X: Unknown Supports Wake-on: d Wake-on: d Current message level: 0x00000007 (7) drv probe link Link detected: yes Server B Network Card Information Settings for eth2: Supported ports: [ FIBRE ] Supported link modes: 10000baseT/Full Supported pause frame use: No Supports auto-negotiation: No Advertised link modes: 10000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: No Speed: 10000Mb/s Duplex: Full Port: Direct Attach Copper PHYAD: 0 Transceiver: external Auto-negotiation: off Supports Wake-on: d Wake-on: d Current message level: 0x00000007 (7) drv probe link Link detected: yes The problem is : as you can see from iperf utility, the transfer speed from server A to server B slow when i restart network service the connection will be ok , after 2 minutes , it's getting slow How could i troubleshoot slow speed issue and fix it in server B ? Notice : if there any other commands i should execute in servers for more information, so it might help resolve the problem , let me know in comments

  • SWATCH - what am I doing wrong?

    - by Brian Dunbar
    What I want/need/desire is to log when a user logs into my FTP server. Problem: I can't make swatch work the way I should be able to. This data is logged to a file - but of course these logs are not kept very long. I can't keep the logs around forever, but I can extract data from then, analyze it, store results elsewhere. If there is a better way to do this than the following, I'm all ears. Swatch version 3.2.3 Perl 5.12 FTP: VSFTP OS (Test): OS X 10.6.8 OS (Production): Solaris From man I see I can pass contents to a command .. so I should be able to echo those values to file, do a sed/cut/uniq thing on them for stats. $ man swatch (snip) exec command Execute command. The command may contain variables which are substituted with fields from the matched line. A $N will be replaced by the Nth field in the line. A $0 or $* will be replaced by the entire line. Swatch file .swatchrc watchfor /OK LOGIN/ echo=red pipe "echo "0: $0 1:$1 2:$2 3:$3 4:$4 5:$5" >> /Users/bdunbar/dev/ftplog/output.txt" Launch with $ swatch -c /Users/bdunbar/.swatchrc --script-dir /Users/bdunbar/dev/ftplog -t /Users/bdunbar/dev/ftplog/vsftpd.log & Test echo "Mon July 9 03:11:07 2012 [pid 14938] [aetech] OK LOGIN: Client "206.209.255.227"" >> vsftpd.log Results - it's echoing to TTY.

  • Bundler isn't loading gems

    - by Garrett
    I have been having a problem with using Bundler and being able to access my gems without having to require them somewhere, as config.gem used to do that for me (as far as I know). In my Rails 3 app, I defined my Gemfile like so: clear_sources source "http://gemcutter.org" source "http://gems.github.com" bundle_path "vendor/bundler_gems" ## Bundle edge rails: git "git://github.com/rails/arel.git" git "git://github.com/rails/rack.git" gem "rails", :git => "git://github.com/rails/rails.git" ## Bundle gem "mongo_mapper", :git => "git://github.com/jnunemaker/mongomapper.git" gem "bluecloth", ">= 2.0.0" Then I run gem bundle, it bundles it all up like expected. Inside the environment.rb file that is included within boot.rb it looks like this: # DO NOT MODIFY THIS FILE module Bundler file = File.expand_path(__FILE__) dir = File.dirname(file) ENV["PATH"] =

same goes for any other gem. Does Bundler not include gems like the old Rails 2.0 did? Or is something messed up with my system? Any help would be appreciated, thank you!

  • Tweaking Remote Control (In-Kernel LIRC)

    - by Geoff
    I've recently rebuilt my MythTV box using Mythbuntu 12.04, to take advantage of newer hardware (Ivy Bridge). On my previous build I used lirc to manage the remote, i.e. the mapping of key codes - keypresses - application keys; it was quite a journey to learn it all, and I ended up fairly comfortable with how it all worked. What I have: I have a cheap Chinavasion remote and USB dongle, which I've found several articles on; these largely revolve around working with XBMC (interesting, but I don't think directly applicable) and also around getting a Harmony remote to work (it's a Chinavasion CVSB-983 - very useful, since I needed this to get my Harmony 900 working). Mythbuntu 12.04 64-bit MythTV 0.25 (likely irrelevant) How it is right now When I plug this in, it 'just works'. Which is great, except that Ubuntu uses it natively, and prevents some of the button presses from getting through to Myth. For example, I can send a button from the remote that equates to Ctrl-Alt-A (which I assume Ubuntu isn't interested in), and then trap that in Mythfrontend, but the remote's Play button is caught by Ubuntu (which displays a large circle with a line though it, as there's no media player loaded). I understand that this is because lirc is merged into the kernel now, and I like that. What I've done so far: Found the device using lsusb: $ lsusb Bus 001 Device 004: ID 073a:2230 Chaplet Systems, Inc. infrared dongle for remote Found the event device number: $ cat /proc/bus/input/devices I: Bus=0003 Vendor=073a Product=2230 Version=0110 N: Name="HID 073a:2230" P: Phys=usb-0000:00:1a.0-1.2/input0 S: Sysfs=/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.2/1-1.2:1.0/input/input5 U: Uniq= H: Handlers=sysrq kbd mouse1 event5 js0 B: PROP=0 B: EV=10001f B: KEY=4c37fff072ff32d bf54445600000000 ffffffffff 30c100b17c007 ffa67bfad951dfff febeffdfffefffff fffffffffffffffe B: REL=343 B: ABS=100030000 B: MSC=10 Tested the input with evtest (I pressed Play): $ sudo evtest /dev/input/event5 Input driver version is 1.0.1 Input device ID: bus 0x3 vendor 0x73a product 0x2230 version 0x110 Input device name: "HID 073a:2230" Supported events: Event type 0 (EV_SYN) Event type 1 (EV_KEY) Event code 1 (KEY_ESC) Event code 2 (KEY_1) Event code 3 (KEY_2) Event code 4 (KEY_3) Event code 5 (KEY_4) Event code 6 (KEY_5) Event code 7 (KEY_6) <------------snipped lots of 'Event code' lines------------> Testing ...

I'd like to either remap each button press to something that Ubuntu/Unity will ignore, or even better pass the keypress directly to Myth (I suspect this later is only possible with lirc, but I could be wrong). I would really like to do this with the in-kernel drivers, i.e. without explicitly loading lirc; if that's the way the world is going, I'd rather find a way to map the current behaviour to what I want, rather than forcing the 'old' arrangement of loading lirc outside the kernel. Learning something new is also worthwhile! My guess: I'm assuming that this will require using setkeycodes, but have had trouble finding enough information to configure this. Any help greatly appreciated!

  • ps forrest for session id

    - by azatoth
    Often I want to get a nice readout what process are running and their relationship; I usually by habit runs ps auxfww and eventual grep for the process in question. Having been thinking about the problem I tried to create an oneliner to get the process tree in ps ufww format for all processes which has the session id specified by arbitrary process name(s); ending up in following code: ps ufww --sid=$(ps -C apache2 -o sess --no-headers | sort | uniq | grep -v -E '^ +0$' | awk 'NR==1{x=$0;next}NF{x=x","$0};END{gsub(/[[:space:]]*/,"",x);print x}') giving for example following output: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 4157 0.0 0.1 41264 3120 ?

Are there anything out there that is easier to "oneline" and gives above or better information? For example I would actually want to have included all childs relative any parent. (uncertain if this should be on SF instead, but felt it was more like an programming question)

  • shell scripting: search/replace & check file exist

    - by johndashen
    I have a perl script (or any executable) E which will take a file foo.xml and write a file foo.txt. I use a Beowulf cluster to run E for a large number of XML files, but I'd like to write a simple job server script in shell (bash) which doesn't overwrite existing txt files. I'm currently doing something like #!/bin/sh PATTERN="[A-Z]*0[1-2][a-j]"; # this matches foo in all cases todo=`ls *.xml | grep $PATTERN -o`; isdone=`ls *.txt | grep $PATTERN -o`; whatsleft=todo - isdone; # what's the unix magic? #tack on the .xml prefix with sed or something #and then call the job server; jobserve E "$whatsleft"; and then I don't know how to get the difference between $todo and $isdone. I'd prefer using sort/uniq to something like a for loop with grep inside, but I'm not sure how to do it (pipes? temporary files?) As a bonus question, is there a way to do lookahead search in bash grep? To clarify: so the simplest way to do what i'm asking is (in pseudocode) for i in `/bin/ls *.xml` do replace xml suffix with txt if [that file exists] add to whatsleft list end done

  • How to replace custom IDs in the order of their appearance with a shell script?

    - by Péter Török
    I have a pair of rather large log files with very similar content, except that some identifiers are different between the two. A couple of examples: UnifiedClassLoader3@19518cc | UnifiedClassLoader3@d0357a JBossRMIClassLoader@13c2d7f | JBossRMIClassLoader@191777e That is, wherever the first file contains UnifiedClassLoader3@19518cc, the second contains UnifiedClassLoader3@d0357a, and so on. I want to replace these with identical IDs so that I can spot the really important differences between the two files. I.e. I want to replace all occurrences of both UnifiedClassLoader3@19518cc in file1 and UnifiedClassLoader3@d0357a in file2 with UnifiedClassLoader3@1; all occurrences of both JBossRMIClassLoader@13c2d7f in file1 and JBossRMIClassLoader@191777e in file2 with JBossRMIClassLoader@2 etc. Using the Cygwin shell, so far I managed to list all different identifiers occurring in one of the files with grep -o -e 'ClassLoader[0-9]*@[0-9a-f][0-9a-f]*' file1.log | sort | uniq However, now the original order is lost, so I don't know which is the pair of which ID in the other file. With grep -n I can get the line number, so the sort would preserve the order of appearance, but then I can't weed out the duplicate occurrences. Unfortunately grep can not print only the first match of a pattern. I figured I could save the list of identifiers produced by the above command into a file, then iterate over the patterns in the file with grep -n | head -n 1, concatenate the results and sort them again. The result would be something like 2 ClassLoader3@19518cc 137 ClassLoader@13c2d7f 563 ClassLoader3@1267649 ... Then I could (either manually or with sed itself) massage this into a sed command like sed -e 's/ClassLoader3@19518cc/ClassLoader3@2/g' -e 's/ClassLoader@13c2d7f/ClassLoader@137/g' -e 's/ClassLoader3@1267649/ClassLoader3@563/g' file1.log > file1_processed.log and similarly for file2. However, before I start, I would like to verify that my plan is the simplest possible working solution to this. Is there any flaw in this approach? Is there a simpler way?

  • Formvalidator from the iframe.

    Hello I have a following formvalidatior function in my document. function formValidator(formid) { var form = cic.$(formid); if(!form) return (''); var errors = []; var len = form.elements.length; for(var elementIdx = 0; elementIdx < len; elementIdx++) { var element = form.elements[elementIdx]; if(!element && !element.getAttribute('validationtype')) return (''); switch (element.getAttribute('validationtype')) { case 'text' : if(cic.getValue(element).strip() == "") errors.push(element.getAttribute('validationmsg')); break; case 'email' : if(!cic.isEmail(cic.getValue(element))) errors.push(element.getAttribute('validationmsg')); break; case 'numeric' : if(isNaN(cic.getValue(element).replace(',', '.'))) errors.push(element.getAttribute('validationmsg')); break; case 'confirm' : if(cic.getValue(cic.$(element.getAttribute('sourcefield'))) !== cic.getValue(element)) errors.push(element.getAttribute('validationmsg')); break; } } return (errors.length > 0) ? '<li>' + errors.uniq().join("<li>") : ''; } It works fine, now I have an Iframe in my document, and that I frame contains the form to validate.

  • How to replace pairs of strings in two files to identical IDs?

  • How do I cover unintuitive code blocks?

    For some reason, I'm having a hard time trying to cover the block of code below. This code is an excerpt from the UNIX uniq command.

  • Get a unique data in a SQL query

    - by Jensen
    Hi, I've a database who contain some datas in that form: icon(name, size, tag) (myicon.png, 16, 'twitter') (myicon.png, 32, 'twitter') (myicon.png, 128, 'twitter') (myicon.png, 256, 'twitter') (anothericon.png, 32, 'facebook') (anothericon.png, 128, 'facebook') (anothericon.png, 256, 'facebook') So as you see it, the name field is not uniq I can have multiple icons with the same name and they are separated with the size field. Now in PHP I have a query that get ONE icon set, for example : $dbQueryIcons = mysql_query("SELECT * FROM pl_icon WHERE tag LIKE '%".$SEARCH_QUERY."%' GROUP BY name ORDER BY id DESC LIMIT ".$firstEntry.", ".$CONFIG['icon_per_page']."") or die(mysql_error()); With this example if $tag contain 'twitter' it will show ONLY the first SQL data entry with the tag 'twitter', so it will be : (myicon.png, 16, 'twitter') This is what I want, but I would prefer the '128' size by default. Is this possible to tell SQL to send me only the 128 size when existing and if not another size ? In an another question someone give me a solution with the GROUP BY but in this case that don't run because we have a GROUP BY name. And if I delete the GROUP BY, it show me all size of the same icons. Thanks !

  • Copy/publish images linked from the html files to another server and update the HTML files referenci

    - by Phil
    I am publishing content from a Drupal CMS to static HTML pages on another domain, hosted on a second server. Building the HTML files was simple (using PHP/MySQL to write the files). I have a list of images referenced in my HTML, all of which exist below the /userfiles/ directory. cat *.html | grep -oE [^\'\"]+userfiles[\/.*]*/[^\'\"] | sort | uniq Which produces a list of files http://my.server.com/userfiles/Another%20User1.jpg http://my.server.com/userfiles/image/image%201.jpg ... My next step is to copy these images across to the second server and translate the tags in the html files. I understand that sed is probably the tool I would need. E.g.: sed 's/[^"]\+userfiles[\/image]\?\/\([^"]\+\)/\/images\/\1/g' Should change http://my.server.com/userfiles/Another%20User1.jpg to /images/Another%20User1.jpg, but I cannot work out exactly how I would use the script. I.e. can I use it to update the files in place or do I need to juggle temporary files, etc. Then how can I ensure that the files are moved to the correct location on the second server

  • Explaining a Ruby code snippet

    - by Michael Foukarakis
    I'm in that uncomfortable position again, where somebody has left me with a code snippet in a language I don't know and I have to maintain it. While I haven't introduced Ruby to myself some parts of it are quite simple, but I'd like to hear your explanations nonetheless. Here goes: words = File.open("lengths.txt") {|f| f.read }.split # read all lines of a file in 'words'? values = Array.new(0) words.each { |value| values << value.to_i } # looked this one up, it's supposed to convert to an array of integers, right? values.sort! values.uniq! diffs = Array.new(0) # this looks unused, unless I'm missing something obvious sum = 0 s = 0 # another unused variable # this looks like it's computing the sum of differences between successive # elements, but that sum also remains unused, or does it? values.each_index { |index| if index.to_i < values.length-1 then sum += values.at(index.to_i + 1) - values.at(index.to_i) end } # could you also explain the syntax here? puts "delta has the value of\n" # this will eventually print the minimum of the original values divided by 2 puts values.at(0) / 2 The above script was supposed to figure out the average of the differences between every two successive elements (integers, essentially) in a list. Am I right in saying this is nowhere near what it actually does, or am I missing something fundamental, which is likely considering I have no Ruby knowledge?

  • Too many TIME_WAIT state connections!

    - by Hamza
    I've been reading about this everywhere all day, and from what I've gathered, TIME_WAIT is a relatively harmless state. It's supposed to be harmless even when there's too many. But if they're jumping to the numbers I've been seeing for the past 24 hours, something is really wrong! [root@1 ~]# netstat -nat | awk '{print $6}' | sort | uniq -c | sort -n 1 established) 1 Foreign 12 CLOSE_WAIT 15 LISTEN 64 LAST_ACK 201 FIN_WAIT2 334 CLOSING 605 ESTABLISHED 816 SYN_RECV 981 FIN_WAIT1 26830 TIME_WAIT That number fluctuates from 20,000 to 30,000+ (so far, the maximum I've seen it go is 32,000). What worries me is that they're all different IP addresses from all sorts of random locations. Now this is supposed to be (or was supposed to be) a DDoS attack. I know this for a fact, but I won't go into the boring details. It started out as a DDoS and it did impact my server's performance for a couple minutes. After that, everything was back to normal. My server load is normal. My internet traffic is normal. No server resource is being abused. My sites load fine. I also have IPTABLES disabled. There's an odd issue with that too. Every time I enable the firewall/iptables, my server starts experiencing packet loss. Lots of it. About 50%-60% packets are lost. It happens within an hour or within a few hours of enabling the firewall. As soon as I disable it, ping responses from all locations I test them from start clearing up and get stable again. Very strange. The TIME_WAIT state connections have been fluctuating at those numbers since yesterday. For 24 hours now, I've had that, and although it hasn't impacted performance in any way, it's disturbing enough. My current tcp_fin_timeout value is 30 seconds, from the default 60 seconds. However, that seems to not help, at all. Any ideas, suggestions? Anything at all would be appreciated, really!

  • How to export computers from Active Directory to XML using Powershell?

    - by CoDeRs
    I am trying to create a powershell scripts for Remote Desktop Connection Manager using the active directory module. My first thought was get a list of computers in AD and parse them out into XML format similar to the OU structure that is in AD. I have no problem with that, the below code will work just but not how I wanted. EG # here is a the array $OUs Americas/Canada/Canada Computers/Desktops Americas/Canada/Canada Computers/Laptops Americas/Canada/Canada Computers/Virtual Computers Americas/USA/USA Computers/Laptops Computers Disabled Accounts Domain Controllers EMEA/UK/UK Computers/Desktops EMEA/UK/UK Computers/Laptops Outside Sales and Service/Laptops Servers I wanted to have the basic XML structured like this Americas Canada Canada Computers Desktops Laptops Virtual Computers USA USA Computers Laptops Computers Disabled Accounts Domain Controllers EMEA UK UK Computers Desktops Laptops Outside Sales and Service Laptops Servers However if you run the below it does not nest the next string in the array it only restarts the from the beginning and duplicating Americas Canada Canada Computers Desktops

  • apache webserver unresponsible with server-status showing all child processes waiting for connection

    - by Jeff
    My setup: i have 3 nearly identical webserver machines serving the same high loaded dynamic website with simple load balancing over dns. The service has been working for over two ears with the same apache config. apache2, php5, ubuntu 8.04 linux 2.6.24-29-server My problem: since about two weeks i'm experiencing problems with this config. Nearly every day i have one small moment about 5 minutes, in which the website is unreachable. I'm still able to login to the servers over ssh. If i run htop, i see the machine simply doing nothing. i have about 1000 apache processes running, but no cpu activity. i've used the apache mod_status to debug this situation. the process scoreboard looks like this: _C.___K_______________________R._______.__K_K____K___C_______.__ _______C__________.___________________________________.________C _.____K__________K___K_WK_____._K_____________________________._ W______K__________K________.____________________._______C_______ _C_.__K__K____.._.._____________________________________C_______ _R___________K___.______C________.C_________.______._____C______ ____________KKC____K_____K__WC_________________C_____.__.____.__ _____________________C_________K______.____C______._____________ _.___C____.___.___________________________.K______.____K________ W__.___________________C.__.____K________K_______R_._.__._______ __C__C_.__________C__C_______._____W______________C_.___C_______ ____.______C_____________C________.____C____________.________._K __.__________.K_____________K_________._____C____.K__________KW_ __K.W________R_________._______.___W___________.____.__K_____W__ W___.___..________W____K Scoreboard Key: "_" Waiting for Connection, "S" Starting up, "R" Reading Request, "W" Sending Reply, "K" Keepalive (read), "D" DNS Lookup, "C" Closing connection, "L" Logging, "G" Gracefully finishing, "I" Idle cleanup of worker, "." Open slot with no current process So the most of the processes are just waiting for connection. after about 5 minutes the situation will return to normal: i have lot least processes on every machine, the most workers have the "."-status (meaing they are open to process a request) and of course the website is reachable! so i'm trying to find something in the logs, but there is simply nothing... the apache access log is silent for about 4 minutes, the same is for the error log. i also can not figure out anything wrong in other system logs. the situation is the same on all 3 webservers (all of them have this load peak and unresposibility at the same time), so i do not thing this is hardware related. but i think, this might be related to some network (tcp) issue. any ideas? EDIT: some more information, that i have just discovered: it has just happened again. and i was able to verify that i'm also not able to connect locally when this problem occurs. i have made some connection statistics with the following command after it happend netstat -an|awk '/tcp/ {print $6}'|sort|uniq -c 109 CLOSE_WAIT 2652 ESTABLISHED 2 FIN_WAIT1 11 LAST_ACK 12 LISTEN 91 SYN_RECV 1 SYN_SENT 16 TIME_WAIT If i execute the same command some time later, i have something like this: 4 CLOSING 108 ESTABLISHED 18 FIN_WAIT1 182 FIN_WAIT2 37 LAST_ACK 12 LISTEN 50 SYN_RECV 11276 TIME_WAIT So in the normal situation i have only 100-200 open connections by clients beeing handled by apache in this moment. when i have this "crash", i have a lot more connections. what is the best way to analyse this? EDIT2: the important lines in apache2.conf are: KeepAlive On MaxKeepAliveRequests 20 KeepAliveTimeout 1 <IfModule mpm_prefork_module> ServerLimit 920 StartServers 30 MinSpareServers 80 MaxSpareServers 120 MaxClients 920 MaxRequestsPerChild 700 </IfModule> it is an apache2 prefork with php_mod. the server has 8GB ram and a 4gb swap partition.

  • Possible to give one connection to each IP?

    - by Alice
    I am having overloading problems. Too many connections, and some IP has more than 20 connection at once. I do this command. netstat -anp |grep 'tcp\|udp' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n To get total of connection and this is the output: 1 106.3.98.81 1 106.3.98.82 1 108.171.251.2 1 110.85.103.207 1 111.161.30.217 1 113.53.103.55 1 119.235.237.20 1 124.106.19.34 1 157.55.32.166 1 157.55.33.49 1 157.55.34.28 1 175.141.103.239 1 180.76.5.59 1 180.76.5.61 1 188.235.165.216 1 205.213.195.70 1 216.157.222.25 1 218.93.205.100 1 222.77.209.105 1 27.153.148.109 1 27.159.194.242 1 27.159.253.71 1 54.242.122.201 1 61.172.50.99 1 65.55.24.239 1 71.179.78.5 1 74.125.136.27 1 74.125.182.30 1 74.125.182.36 1 79.112.225.39 1 93.190.139.208 2 124.227.191.67 2 157.55.33.84 2 157.55.35.34 2 190.66.3.107 2 203.87.153.38 2 220.161.119.3 2 221.6.15.156 2 27.153.148.116 2 27.159.197.0 2 96.47.224.42 3 202.14.70.1 3 218.6.15.42 3 222.77.218.226 3 222.77.224.187 3 37.59.66.100 3 46.4.181.244 3 87.98.254.192 3 91.207.8.62 4 188.143.233.222 4 218.108.168.166 4 221.12.154.18 4 93.182.157.8 4 94.142.128.183 5 180.246.170.187 5 8.21.6.226 6 178.137.94.87 6 218.93.205.112 7 199.15.234.222 9 9 125.253.97.6 10 178.137.17.196 11 46.118.192.179 12 212.79.14.14 21 72.201.187.135 27 0.0.0.0 Can anyone give me some directions, my server crashed few times this week because of this.
