  • High disk I/O activity in CentOS server

    - by triiim
    I have about 16 websites in a CentOS dedicated, and I am having some problems on high traffic hours, it seems to be a high disk I/O activity causing a general slowdown. I've installed atop and this is what I see on the bottom (the server has been restarted thats why the values are so low): *** system and process activity since boot *** PID RDDSK WRDSK WCANCL DSK CMD 1/18 2176 1.7G 7.3G 854.4M 39 mysqld 671 1248K 3.0G 0K 13 flush-8:0 566 0K 1.1G 0K 5 jbd2/sda2-8 2401 124.2M 529.1M 22408K 3 crond 2032 2.2G 502.0M 0K 12 nginx 2360 425.8M 115.3M 4188K 2 httpd flush-8:0 and jbd2/sda2-8 are the processes I see with iotop using 99% on the IO column, and they are the processes that write the most on the hdd (after mysql). From what I saw in google this could be caused by some ext4 related bug, the current kernel is: Linux srvr.com 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux I asked the hosting support to update the kernel and they tried but they now say that the server wont boot with the new installed kernel and they had to go back to the previous, they are not helping very much. Does someone has any idea how could I solve the high disk usage caused by flush-8:0 and jbd2/sda2-8 processes?

  • Discover the public ip of a network without being connected

    - by Martin Trigaux
    Let say, I'm next to a network and can see the traffic (with airodump or similar tool) but can not decipher it (because I am not connected on the network). Is it possible to discover the public ip address of the network ? I know the MAC address of the users connected on the network but do I know the one of the router ? If yes, maybe there is a way to do the matching. I know IP addresses are not forever but some addresses are static and never change. Maybe there is a database of MAC address having recorded that. Google has a database that match MAC address and geographical coordinates so why not with IP addresses ? Other idea, if I know where am I, I can maybe guess the IP range used in the city by the ISP (is it findable ?) and then try to "ping" each IP on the range (if it is a /24, it's possible, even /16 maybe). Will I get some information like the MAC of the box or see some traffic on the network ? These are two ideas I had. I don't know if they are doable, certainly not perfect. Do you think of some others ? By trying several methods, maybe I can get a guess with a bit of luck. Thank you

  • Microsoft Word "Random" Crashes

    - by Bent Rasmussen
    Word seemingly randomly crashes in an application setting where it is first being used to programmatically databind (bookmarks) and then directly afterwards opened on the user machine for further user input. The error message is quite precise but the workaround has eluded me. Word crashes a moment or two after it has been opened on the user machine with the below exception details. Problem signature: Problem Event Name: APPCRASH Application Name: WINWORD.EXE Application Version: 14.0.6129.5000 Application Timestamp: 5082f354 Fault Module Name: wwlib.dll Fault Module Version: 14.0.6129.5000 Fault Module Timestamp: 5082f3dc Exception Code: c0000005 Exception Offset: 000eed32 OS Version: 6.1.7601.2.1.0.16.7 Locale ID: 1030 Additional information about the problem: LCID: 1030 skulcid: 1030 Sometimes one can run the exact same scenario 50 times before experiencing a crash, other times only a few times. We have tried using different versions of the Word format as well as renaming the databound file after saving so that the file being opened on the user machine is different. Principally Word should never crash but perhaps there is some workaround that can make Word not crash. Googling for a solution there appears to be multiple things that can trigger this bug.

  • Many different BSOD

    - by Exa
    I'm experiencing multiple bluescreens for a couple of months now. Their error code is as diverse as their time of occurence... Sometimes it happens during gaming, sometimes when watching videos, sometimes when the computer is idle. These are the bluescreens I see most often: PAGE_FAULT_IN_NONPAGED_AREA KMODE_EXCEPTION_NOT_HANDLED IRQL_NOT_LESS_OR_EQUAL SYSTEM_SERVICE_EXCEPTION SYSTEM_THREAD_EXCEPTION INTERRUPT_EXCEPTION_NOT_HANDLED DRIVER_IRQL_NOT_LESS_OR_EQUAL DRIVER_OVERRAN_STACK_BUFFER Responsible drivers (according to the memory dumps): hal.dll tcpip.sys dxgmms1.sys ndis.sys mouhid.sys atikmdag.sys dump_atapi.sys and of course: ntoskrnl.exe My first thought was a driver incompatibility because I am using Windows 8 and some of the bluescreens seem to come from driver issues. All drivers are up to date. I'm afraid that my memory is broken or the mainboard or both. I used the windows integrated memtest which didn't find any errors. Memtest86 found some errors. Does it make sense to buy new memory? Couldn't it be a problem of the board as well? I also read that my memory could run at a too low voltage. But it's set to 1.5V as recommended. Another guess would be to set the memory's latencies manually, but how do I know which ones to try? Here is a screenshot of bluescreenview showing the latest bluescreens. Maybe someone has faced the same behavior before and found a solution. Any ideas or suggestions? Current setup on which the bluescreens occur.

  • Recommended Win2k8 Server software to fix my RAID-0 issue

    - by Jason Kealey
    I'm running an Asus P6T V2 Deluxe. It has six SATA ports and supports onboard RAID. I am using two of those ports for a RAID0 array of 1.5TB Seagate drives using the onboard RAID controller. One of them is giving me SMART warnings and I want to preemptively replace it. I pulled out two other 1.5TB drives from another computer and am ready to use one or both, if necessary. I can't run any SMART diagnostic software from within Windows because it only sees the hardware RAID-0 array, not each individual drive. The first thing I tried was a slow sector-by-sector copy using a free tool called EASEUS Disk Copy. Used the bootdisk, copied (took like 16 hours), unplugged the defective drive and plugged the new one in its place. The motherboard didn't recognize the new drive as being part of the known setup, so it did not want to boot. The second thing I tried was using other software (I forget the name) to copy the partition from within Windows. The first software failed because I had a server operating system. I found another software (I forget the name) which supported a server OS and did a partition copy onto the new drive. This seemed to work and the OS started to boot, but blue screened and started a reboot cycle. I'm assuming the software I was using was no good as it was trying to copy the boot disk while it was in use. I am looking for recommendations on what software to use to fix my problem without doing a re-install. Everything is backed up but my computer works fine and I'd like to avoid re-installation when possible. However, my system would be back up now if I had just started over on a second RAID array. :)

  • xen + debian network after upgrade squeeze to wheeze

    - by rush
    I've got a Debian + Xen server. After a system upgrade to the stable version the network doesn't come up after boot. Every time after reboot I need to bring it up manually. The network configuration was not changed during upgrade. Here is /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 11.22.33.44 netmask 255.255.255.0 gateway 11.22.33.1 nameserver 8.8.8.8 After boot ip r shows no route and eth0 has no ip address.

  • OpenVPN + iptables / NAT routing

    - by Mikeage
    Hi, I'm trying to set up an OpenVPN VPN, which will carry some (but not all) traffic from the clients to the internet via the OpenVPN server. My OpenVPN server has a public IP on eth0, and is using tap0 to create a local network, 192.168.2.x. I have a client which connects from local IP 192.168.1.101 and gets VPN IP 192.168.2.3. On the server, I ran: iptables -A INPUT -i tap+ -j ACCEPT iptables -A FORWARD -i tap+ -j ACCEPT iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -o eth0 -j MASQUERADE On the client, the default remains to route via 192.168.1.1. In order to point it to 192.168.2.1 for HTTP, I ran ip rule add fwmark 0x50 table 200 ip route add table 200 default via 192.168.2.1 iptables -t mangle -A OUTPUT -j MARK -p tcp --dport 80 --set-mark 80 Now, if I try accessing a website on the client (say, wget google.com), it just hangs there. On the server, I can see $ sudo tcpdump -n -i tap0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tap0, link-type EN10MB (Ethernet), capture size 96 bytes 05:39:07.928358 IP 192.168.1.101.34941 > 74.125.67.100.80: S 4254520618:4254520618(0) win 5840 <mss 1334,sackOK,timestamp 558838 0,nop,wscale 5> 05:39:10.751921 IP 192.168.1.101.34941 > 74.125.67.100.80: S 4254520618:4254520618(0) win 5840 <mss 1334,sackOK,timestamp 559588 0,nop,wscale 5> Where 74.125.67.100 is the IP it gets for google.com . Why isn't the MASQUERADE working? More precisely, I see that the source showing up as 192.168.1.101 -- shouldn't there be something to indicate that it came from the VPN? Edit: Some routes [from the client] $ ip route show table main 192.168.2.0/24 dev tap0 proto kernel scope link src 192.168.2.4 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.101 metric 2 169.254.0.0/16 dev wlan0 scope link metric 1000 default via 192.168.1.1 dev wlan0 proto static $ ip route show table 200 default via 192.168.2.1 dev tap0

  • How do I restore tab-completion on shell variables on the bash command-line?

    - by Eric
    I've long set my most-recently visited directories to shell variables d1, d2, etc. On an ancient Fedora machine I could type a command like $ cp $d1/ and the shell would replace $d1 with text like /home/acctname/projects/blog/ and would then show me the contents of .../blog, like any tab-completion. Now, both ubuntu wheezy/sid and fedora 16 just -escape the '$', and naturally there are no completions to show. You can see this behavior in action in an OSX Terminal window. On 10.8, do something like ls $HOME/ to see what I mean. Is there a bash shell variable or option that can restore the old behavior? man bash suggests this is a bug: complete (TAB) Attempt to perform completion on the text before point. Bash attempts completion treating the text as a variable (if the text begins with $), username (if the text begins with ~), hostname (if the text begins with @), or command (including aliases and functions) in turn. If none of these produces a match, filename completion is attempted. I get the above described completion when a token starts with '~' or a letter. It's just '$'-completion that's broken.

  • Fortigate restrict traffic through one external IP

    - by Tom O'Connor
    I've got a fortigate 400A at a client's site. They've got a /26 from British Telecom, and we're using 4 of those IPs as a NAT Pool. Is there a way to say that traffic from 172.18.4.40-45 can only ever come out of (and hence go back into) x.x.x.140 as the external IP? We're having some problems with SIP which looks like it's coming out of one, and trying to go back into another. I tried enabling asymmetric routing, didn't work. I tried setting a VIP, but even when I did that, it didn't appear to do anything. Any ideas? I can probably post some firewall snippets if need be.. Tell me what you want to see. SIP ALG config system settings set sip-helper disable set sip-nat-trace disable set sip-tcp-port 5061 set sip-udp-port 5061 set multicast-forward enable end Interesting Sidenote VoIP phones, with no special configuration can register fine to proxy.sipgate.co.uk, which has an IP address of 217.10.79.16. Which is cool. Two phones are using a different provider, whose proxy IP address is 178.255.x.x. These phones can register for outbound, but inbound INVITEs never make it to the phone. Is it possible that the Fortigate is having trouble with 178.255.x.x as it's got a 255 in it? Or am I just imagining things?

  • nginx: js file loads indifferently every refresh

    - by poymode
    I have this nginx problem wherein a js file in a rails app loads indifferently. Whenever I try to access the JS file in the browser and refresh the page, the scrollbar changes length meaning sometimes it loads half the js page, sometimes the whole and sometimes just a part of it. the js file size is 71K. my nginx server is on different server,separate from my rails app. when I try to access the js file directly through the app server, lets say 10.48.30.150:3000/javascripts/file.js it works fine and doesnt show any half-loaded page. but when I use the nginx server which upstreams the rails app, it shows the indifferent page loads. here is my nginx http conf error_log /usr/local/nginx/logs/error.log; pid /usr/local/nginx/logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 256; access_log /usr/local/nginx/logs/access.log; sendfile on; #tcp_nopush on; keepalive_timeout 0; tcp_nodelay on; #gzip on; #gzip_min_length 4096; #gzip_buffers 16 8k; #gzip_types application/x-javascript text/css text/plain; large_client_header_buffers 4 8k; client_max_body_size 2G; include /usr/local/nginx/conf.d/*.conf; }

  • What should the memory configuration be?

    - by AngryHacker
    We have a server (ProLiant DL585 G1 by HP), which hosts Windows 2003 x64 R2 with SQL Server 2005 x64 and a host of other apps. It currently has 6GB of RAM. We are currently very memory constrained and it's clear that we need to get more memory. 8GB will probably do the trick, however, we are not sure as to what memory configuration will give us the biggest performance buck. Currently all 8 memory slots are filled (4 slots have 1GB chip, while the other 4 slots have 512MB chips). Should we throw the 512MB sticks away and just replace them all with 1GB sticks? If we decided to go with a higher memory configuration (e.g. 10GB or 12GB or 16GB), is it advisable to keep all the sticks of the same size or it does not matter? I was once told that interleaved memory requires (for better performance) that memory should be in multiples (e.g. 2 or 4 or 8 or 16, etc...). I am not even sure that the server has an interleaved configuration (and don't know how to find out), but is this true? Thanks.

  • Unable to resize ec2 ebs root volume

    - by nathanjosiah
    I have followed many of the tutorials that pretty much all say the same thing which is basically: Stop the instance Detach the volume Create a snapshot of the volume Create a bigger volume from the snapshot Attach the new volume to the instance Start the instance back up Run resize2fs /dev/xxx However, step 7 is where the problems start happening. In any case running resize2fs always tells me that it is already xxxxx blocks big and does nothing, even with -f passed. So I start to continue with tutorials which all basically say the same thing and that is: Delete all partitons Recreate them back to what they were except with the bigger sizes Reboot the instance and run resize2fs (I have tried these steps both from the live instance and by attaching the volume to another instance and running the commands there) The main problem is that the instance won't start back up again and the system error log provided in the AWS console doesn't provide any errors. (it does however stop at the grub bootloader which to me indicates that it doesn't like the partitions(yes, the boot flag was toggled on the partition with no affect)) The other thing that happens regardless of what changes I make to the partitions is that the instance that the volume is attached to says that the partition has an invalid magic number and the super-block is corrupt. However, if I make no changes and reattach the volume, the instance runs without a problem. Can anybody shed some light on what I could be doing wrong? Edit On my new volume of 20GB with the 6GB image,df -h says: Filesystem Size Used Avail Use% Mounted on /dev/xvde1 5.8G 877M 4.7G 16% / tmpfs 836M 0 836M 0% /dev/shm And fdisk -l /dev/xvde says: Disk /dev/xvde: 21.5 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x7d833f39 Device Boot Start End Blocks Id System /dev/xvde1 1 766 6144000 83 Linux Partition 1 does not end on cylinder boundary. /dev/xvde2 766 784 146432 82 Linux swap / Solaris Partition 2 does not end on cylinder boundary.

  • Limited connections to Ubuntu 12.04 server

    - by Luis M. Valenzuela
    I'm having a weird problem with my server. The server is inside my network, connected to a 3com switch which is connected to the router that handles the internet connection. The main purpose of the server is to host a php application. What's happening is that user 1 to 15 in the private network have no problems connecting to the server, when user 16 tries to connect a time out comes out and is unable to connect to the server. It's not just to the php application, but to any service from the server. When the 15 users are using the application, the server doesn't even answer to ping. I haven't set any special limit in Apache's ini file or MySql and the firewall is being turned off because the server is only to give service to the internal network. Is there a parameter in any of the network's card conf. files that might me causing this ? Or should I suspect from the router's or switches configuration ? UPDATE. Tomorrow, I'm gonna do some test on the server modifying two kernel params in : /etc/sysctl.conf The settings are: net.core.somaxconn which has the limit on simultaneous network connections to the server and kernel.shmmax which controls the amount of memory the system can use for managing connections.

  • Can't Connect SQL server - process being used by another process. Conflict with IIS?

    - by shinya
    I'm having problem connecting to MS SQL Server (2012 Express) after accessing a database through IIS (web site). I can access the data through web site no problem, but I can't access the data from any other programs (i.e SSMS) until I reboot the SQL server. It seems that the connection stays open even if I close a browser. Here is error message I'm getting Unable to open the physical file "C:---------". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Unable to open the physical file "C:-------". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Cannot open user default database. Login failed. Login failed for user 'Myserver\myname'. (.Net SqlClient Data Provider) Server Name: MYPC\SQLEXPRESS Error Number: 5120 Severity: 16 State: 101 Line Number: 65536 I follow the help link and it told me to move TCP before named pipes in the protocol order list. I tried it but it didn't help at all. What is the proper settings on SQL server or IIS in order to release process after closing a browser. How do I avoid getting this error? Thank you for your help

  • Trouble Letting Users Get to Certain Sites through Squid Proxy

    - by armani
    We have Squid running on a RHEL server. We want to block users from getting to Facebook, other than a couple specific sites, like our organization's page. Unfortunately, I can't get those specific pages unblocked without allowing ALL of Facebook through. [squid.conf] # Local users: acl local_c src 192.168.0.0/16 # HTTP & HTTPS: acl Safe_ports port 80 443 # File containing blocked sites, including Facebook: acl blocked dst_dom_regex "/etc/squid/blocked_content" # Whitelist: acl whitelist url_regex "/etc/squid/whitelist" # I do know that order matters: http_access allow local_c whitelist http_access allow local_c !blocked http_access deny all [blocked_content] .porn_site.com .porn_site_2.com [...] facebook.com [whitelist] facebook.com/pages/Our-Organization/2828242522 facebook.com/OurOrganization facebook.com/media/set/ facebook.com/photo.php www.facebook.com/OurOrganization My biggest weakness is regular expressions, so I'm not 100% sure about if this is all correct. If I remove the "!blocked" part of the http_access rule, all of Facebook works. If I remove "facebook.com" from the blocked_content file, all of Facebook works. Right now, visiting facebook.com/OurOrganization gives a "The website declined to show this webpage / HTTP 403" error in Internet Explorer, and "Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED): Unknown error" in Chrome. WhereGoes.com tells me the URL redirects for that URL goes like this: facebook.com/OurOrganization -- [301 Redirect] -- http://www.facebook.com/OurOrganization -- [302 Redirect] -- https://www.facebook.com/OurOrganization I tried turning up the debug traffic out of squid using "debug_options ALL,6" but I can't narrow anything down in /var/log/access.log and /var/log/cache.log. I know to issue "squid -k reconfigure" whenever I make changes to any files.

  • ddwrt client brigde acces point lost

    - by llazzaro
    Ok I have an AP with ddwrt firm (i know its not the best, but continue reading!) AP is configured to work like a wifi "transparent" brigde, also it had a virtual wifi network card to expand radius of wifi signal in that same AP. The brigde is working, computers behind AP gets ips from main routers which shares internet....BUT! I cant access webgui of the bridge AP... Main problem : AP is lost, but its working as brigde. I cant find it in the network (it didnt have any ip!) so I cant change any configuration... First solution : Reset AP, but it cannot be done. Reset button dont works due to a bug in ddwrt micro firm that mi linksys WAP54g had installed (I really hate this firmware I like more openwrt that my main router has) Second Solution : arp -a from main router , from computers behind AP...It dont appears in the list. Any more ideas, the router at some level must be there, the brigde is working. I know its possible that the AP is with an ip like 192.168.100.2 , my subnect actually is 172.16.X.X. :) thanks!

  • DRBD as a block device for XEN VM (Centos 5.3)

    - by SaberTooth
    Hi all, I have setup a drbd resource between 2 server nodes - everything works correctly when doing sync tests between the two. (I want to create a HA cluster using drbd,xen and heartbeat) However, when I try and create a XEN VM with Centos as guest operating system, I get through to the partitioning screen on the install but when I select a partitioning type the next screen gives me the following error : "An error has occurred - no valid devices were found on which to create new file systems. Please check your hardware for the cause of this problem." This is the first time attempting create a setup like this and searching Google does not help much... my config files for DRBD and XEN....

  • lighttpd on Fedora permission issues

    - by Isaac Gateno
    I'm trying to get started with lighttpd on Fedora 16 to run a RESTful api for development. Right now even with the most basic sample config file I'm getting 404 pages when I know the pages I'm pointing at exist. From reading other questions I'm leaning towards this being a permissions issue, but I'm confused about how lighttpd runs on Fedora. There's a user called "lighttpd" not "www-data"? I can't see this user in the system-config-users tool and I can't su into it to check which permissions it has. I'm trying to point lighttpd to "/var/www/lighttpd" which has some example pages in it. The permissions for the files inside are set to -rw-r--r-- and the permissions for the folder containing them are drwxr-xr-x. Doesn't that mean that any user can view these files? I'm not sure what else I should be checking as I don't have much experience with server configuration. Any help would be appreciated. Edit: I was following the tutorial configuration here so the lighttpd.conf file contains server.document-root = "/var/www/lighttpd/" server.port = 3000 mimetype.assign = ( ".html" => "text/html", ".txt" => "text/plain", ".jpg" => "image/jpeg", ".png" => "image/png" ) and I was just trying to get the basic example page working.

  • OpenVPN + iptables / NAT routing

    - by Mikeage
    I'm trying to set up an OpenVPN VPN, which will carry some (but not all) traffic from the clients to the internet via the OpenVPN server. My OpenVPN server has a public IP on eth0, and is using tap0 to create a local network, 192.168.2.x. I have a client which connects from local IP 192.168.1.101 and gets VPN IP 192.168.2.3. On the server, I ran: iptables -A INPUT -i tap+ -j ACCEPT iptables -A FORWARD -i tap+ -j ACCEPT iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -o eth0 -j MASQUERADE On the client, the default remains to route via 192.168.1.1. In order to point it to 192.168.2.1 for HTTP, I ran ip rule add fwmark 0x50 table 200 ip route add table 200 default via 192.168.2.1 iptables -t mangle -A OUTPUT -j MARK -p tcp --dport 80 --set-mark 80 Now, if I try accessing a website on the client (say, wget google.com), it just hangs there. On the server, I can see $ sudo tcpdump -n -i tap0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tap0, link-type EN10MB (Ethernet), capture size 96 bytes 05:39:07.928358 IP 192.168.1.101.34941 > 74.125.67.100.80: S 4254520618:4254520618(0) win 5840 <mss 1334,sackOK,timestamp 558838 0,nop,wscale 5> 05:39:10.751921 IP 192.168.1.101.34941 > 74.125.67.100.80: S 4254520618:4254520618(0) win 5840 <mss 1334,sackOK,timestamp 559588 0,nop,wscale 5> Where 74.125.67.100 is the IP it gets for google.com . Why isn't the MASQUERADE working? More precisely, I see that the source showing up as 192.168.1.101 -- shouldn't there be something to indicate that it came from the VPN? Edit: Some routes [from the client] $ ip route show table main 192.168.2.0/24 dev tap0 proto kernel scope link src 192.168.2.4 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.101 metric 2 169.254.0.0/16 dev wlan0 scope link metric 1000 default via 192.168.1.1 dev wlan0 proto static $ ip route show table 200 default via 192.168.2.1 dev tap0
