  • DVD drive doesn't recognize blank dvds only!!!

    - by Jack
    My dvd-rom works fine because I can play dvds on it, however when the dvd is a blank one the drive refuses to recognize it. So I can't burn dvds anymore because the drive shows up as empty in my disk burning software (dvd flick). Any idea what the problem is and how to solve it? PC: Windows vista home basic, 32 bit

  • Issue with VMWare vSphere and NFS: re occurring apd state

    - by Bastian N.
    I am experiencing issues with VMWare vSphere 5.1 and NFS storage on 2 different setups, which result in an "All Path Down" state for the NFS shares. This first happened once or twice a day, but lately it occurs much more frequent, as specially when Acronis Backup jobs are running. Setup 1 (Production): 2 ESXi 5.1 hosts (Essentials Plus) + OpenFiler with NFS as storage Setup 2 (Lab): 1 ESXi 5.1 host + Ubuntu 12.04 LTS with NFS as storage Here is an example from the vmkernel.log: 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 248: APD Timer started for ident [987c2dd0-02658e1e] 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 395: Device or filesystem with identifier [987c2dd0-02658e1e] has entered the All Paths Down state. 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 846: APD Start for ident [987c2dd0-02658e1e]! 2013-05-28T08:07:37.485Z cpu0:2052)NFSLock: 610: Stop accessing fd 0x410007e4cf28 3 2013-05-28T08:07:37.485Z cpu0:2052)NFSLock: 610: Stop accessing fd 0x410007e4d0e8 3 2013-05-28T08:07:41.280Z cpu1:2049)StorageApdHandler: 277: APD Timer killed for ident [987c2dd0-02658e1e] 2013-05-28T08:07:41.280Z cpu1:2049)StorageApdHandler: 402: Device or filesystem with identifier [987c2dd0-02658e1e] has exited the All Paths Down state. 2013-05-28T08:07:41.281Z cpu1:2049)StorageApdHandler: 902: APD Exit for ident [987c2dd0-02658e1e]! 2013-05-28T08:07:52.300Z cpu1:3679)NFSLock: 570: Start accessing fd 0x410007e4d0e8 again 2013-05-28T08:07:52.300Z cpu1:3679)NFSLock: 570: Start accessing fd 0x410007e4cf28 again As long as the issue occurred once or twice a day it really wasn't a problem, but now this issue has impact on the VMs. The VMs get slow or even hang, resulting in a reset through vCenter in the production environment. I searched the web extensively and asked in forums, but till now nobody was able to help me. Based on blog posts and VMWare KB articles I tried the following NFS settings: Net.TcpipHeapSize = 32 Net.TcpipHeapMax = 128 NFS.HartbeatFrequency = 12 NFS.HartbeatMaxFailures = 10 NFS.HartbeatTimeout = 5 NFS.MaxQueueDepth = 64 Instead of NFS.MaxQueueDepth = 64 I already tried other settings like NFS.MaxQueueDepth = 32 or even NFS.MaxQueueDepth = 1. Unfortunately without any luck. It would be great if someone could help me on this issue. It is really annoying. Thanks in advance for all the help. [UPDATE] As I explained in the comment below, here is the network setup: On the production setup the NFS traffic is bound to a separate VLAN with ID 20. I am using a HP 1810 24 Port Switch. The OpenFiler system is connected to the VLAN with 4 Intel GbE NICs with dynamic LACP. The ESXis both have 4 Intel GbE NICs using 2 static LACP trunks containing 2 NICs each. One pair is connected to the regular LAN and the other one to the VLAN 20. And here is a screenshot of the vSwitch: Switch configuration: Port configuration: On the lab setup its a single Intel NIC on each side without VLAN, but with different IP subnet.

    I swap my hard drive to a new computer with vista 32 I get 0x0000007b stop error on bootup I tried using the cd to do the repair but it fails. I think it is because I have the wrong hard drive driver install for vista or it is missing. How can I fix this from the command line

  • Slow Windows Explorer on Windows 7

    - by MadBoy
    I have Laptop with i7 (4 cores), 8GB ram and SSD OCZ Vertex 3 MaxIOPS which in testing that I did just now does 400mb/s+ read/write. However the responsiveness of Windows Explorer is far from being perfect. Opening up Computer, Documents, going into folders is very slow (1-5seconds). I don't have any viruses or spyware and I have tried changing properties to optimize view for General Items. I tried disabling Search Indexer but it made search in Outlook 2010 crawl and didn't bring any other effect. Even double clicking on file takes some time to open things up (like clicking a Word document). I don't have any drives mapped, my computer is not joined to domain. I have multiple VPN connections that I connect to but they all have disabled default gateways. I tried using CC Cleaner or some Windows 7 Tweaks app to disable some things. I am power user using Visual Studio, Tortoise SVN and other developer/administration apps. Any non obvious ideas? Edit: So I've been trying to pinpoint where the issue comes from and it seems that straight after reboot Windows Explorer opens very fast, when I load 3-4 programs (Royal TS, Visual Studio, Outlook) it's noticeably slower and the more programs I have it gets worse. After I start closing programs it starts working better and if I leave 2 open it's fast again. I tried doing some research with DiskMon and other programs from sysinternals but couldn't find anything suspicious. Below are stats during normal usage with a lots of programs open: - Ram usage with a lot of programs open and no swap file (i disabled it for testing): 6.95GB - CPU usage: 15%, none of the cores takes more then 50% (I have VS 2010 open x 4) HD Tune Pro: OCZ-VERTEX3 MI Benchmark Test capacity: full Read transfer rate Transfer Rate Minimum : 363.9 MB/s Transfer Rate Maximum : 505.5 MB/s Transfer Rate Average : Access Time : Burst Rate : CPU Usage : HD Tune Pro: OCZ-VERTEX3 MI File Benchmark Drive C: Transfer rate test File Size: 500 MB Sequential read 484102 KB/s Sequential write 444714 KB/s Random read 7779 IOPS Random write 16888 IOPS Random read (queue depth = 32) 73007 IOPS Random write (queue depth = 32) 69790 IOPS HD Tune Pro: OCZ-VERTEX3 MI Random Access Test capacity: full Read test Transfer size operations / sec avg. access time max. access time avg. speed 512 bytes 3260 IOPS 0.306 ms 2.106 ms 1.592 MB/s 4 KB 4161 IOPS 0.240 ms 2.006 ms 16.256 MB/s 64 KB 2382 IOPS 0.419 ms 2.367 ms 148.934 MB/s 1 MB 449 IOPS 2.225 ms 4.197 ms 449.407 MB/s Random 809 IOPS 1.235 ms 6.551 ms 410.527 MB/s HD Tune Pro: OCZ-VERTEX3 MI Extra Tests Test capacity: full Random seek 3975 IOPS 0.252 ms 1.941 MB/s Random seek 4 KB 4245 IOPS 0.236 ms 16.583 MB/s Butterfly seek 4086 IOPS 0.245 ms 1.995 MB/s Random seek / size 64 KB 3812 IOPS 0.262 ms 58.606 MB/s Random seek / size 8 MB 120 IOPS 8.348 ms 485.737 MB/s Sequential outer 4524 IOPS 0.221 ms 282.721 MB/s Sequential middle 4429 IOPS 0.226 ms 276.818 MB/s Sequential inner 5504 IOPS 0.182 ms 344.000 MB/s Burst rate 4472 IOPS 0.224 ms 279.475 MB/s

  • Why is my cron daemon is being killed every few minutes? OpenVZ?

    - by user113215
    As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({56, 0}, 0x7fffa7184c80) = 0 stat("crontabs", {st_mode=S_IFDIR|S_ISVTX|0730, st_size=4096, ...}) = 0 stat("/etc/crontab", {st_mode=S_IFREG|0644, st_size=1100, ...}) = 0 stat("/etc/cron.d", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 stat("/etc/cron.d/php5", {st_mode=S_IFREG|0644, st_size=475, ...}) = 0 stat("/etc/cron.d/anacron", {st_mode=S_IFREG|0644, st_size=244, ...}) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0 rt_sigaction(SIGCHLD, NULL, {0x4036f0, [CHLD], SA_RESTORER|SA_RESTART, 0x2b0e8465f230}, 8) = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has about 500 MB of free memory, and cat /proc/loadavg returns 0.10 0.21 0.45 so resources shouldn't be the issue. I also tried removing and reinstalling the cron package using apt-get. What else should I check? How do I find out what's killing my crond? Edit: I'm on a virtual machine under OpenVZ (and as such, I have no swap). With cron running, free -m reports: total used free shared buffers cached Mem: 1024 465 558 0 0 0 -/+ buffers/cache: 465 558 Swap: 0 0 0 My OpenVZ User Beancounters via cat /proc/user_beancounters: Version: 2.5 uid resource held maxheld barrier limit failcnt 172087: kmemsize 8275718 25561636 51200000 51200000 0 lockedpages 0 968 2048 2048 0 privvmpages 113442 266465 262200 262200 3740757 shmpages 788 4004 128000 128000 0 dummy 0 0 0 0 0 numproc 39 98 600 600 0 physpages 50521 208434 0 9223372036854775807 0 vmguarpages 0 0 512000 512000 0 oomguarpages 50521 208447 512000 512000 0 numtcpsock 7 323 4096 4096 0 numflock 7 64 2048 2048 0 numpty 1 4 32 32 0 numsiginfo 0 23 1024 1024 0 tcpsndbuf 137984 17878480 20480000 20480000 0 tcprcvbuf 114688 6983504 20480000 20480000 0 othersockbuf 162960 1074440 20480000 20480000 0 dgramrcvbuf 0 24208 10240000 10240000 0 numothersock 101 353 2048 2048 0 dcachesize 459171 747444 10240000 10240000 0 numfile 1010 4221 50000 50000 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 numiptent 39 424 2048 2048 0

  • Stop squid caching 302 and 307 with deny_info

    - by 0xception
    TLDR: 302, 307 and Error pages are being cached. Need to force a refresh of the content. Long version: I've setup a very minimal squid instance running on a gateway which shouldn't not cache ANYTHING but needs to be solely used as a domain based web filter. I'm using another application which redirects un-authenticated users to the proxy which then uses the deny_info option redirects any non-whitelisted request to the login page. After the user has authenticated the firewall rule gets placed so they no longer get sent to the proxy. The problem is that when a user hits a website (xkcd.com) they are unauthenticated so they get redirected via the firewall: iptables -A unknown-user -t nat -p tcp --dport 80 -j REDIRECT --to-port 39135 to the proxy at this point squid redirects the user to the login page using a 302 (i've also tried 307, and i've also make sure the headers are set to no-cache and/or no-store for Cache-Control and Pragma). Then when the user logs into the system they get firewall rule which no longer directs them to the squid proxy. But if they go to xkcd.com again they will have the original redirection page cached and will once again get the login page. Any idea how to force these redirects to NOT be cached by the browser? Perhaps this is a problem w/ the browsers and not squid, but not sure how to get around it. Full squid config below. # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 acl localnet src 192.168.182.0/23 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl https port 443 acl http port 80 acl CONNECT method CONNECT # # Disable Cache # cache deny all via off negative_ttl 0 seconds refresh_all_ims on #error_default_language en # Allow manager access only from localhost http_access allow manager localhost http_access deny manager # Deny access to anything other then http http_access deny !http # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !https visible_hostname gate.ovatn.net # Disable memory pooling memory_pools off # Never use neigh cache objects for cgi-bin scripts hierarchy_stoplist cgi-bin ? # # URL rewrite Test Settings # #acl whitelist dstdomain "/etc/squid/domains-pre.lst" #url_rewrite_program /usr/lib/squid/redirector #url_rewrite_access allow !whitelist #url_rewrite_children 5 startup=0 idle=1 concurrency=0 #http_access allow all # # Deny Info Error Test # acl whitelist dstdomain "/etc/squid/domains-pre.lst" deny_info http://login.domain.com/ whitelist #deny_info ERR_ACCESS_DENIED whitelist http_access deny !whitelist http_access allow whitelist http_port 39135 transparent ## Debug Values access_log /var/log/squid/access-pre.log cache_log /var/log/squid/cache-pre.log # Production Values #access_log /dev/null #cache_log /dev/null # Set PID file pid_filename /var/run/gatekeeper-pre.pid SOLUTION: I believe I might have found a solution to this. After days and days trying to figure it out, only through a random stumble I found client_persistent_connections off server_persistent_connections off This did the trick. So it wasn't so much cache as it was a single persistent connection messing things up. W000T!

  • configure squid3 to set up a web proxy in ubuntu12.04

    - by Gnijuohz
    I am in a LAN and have to use a proxy given to access the web in a very limited way. I can't even use google, github.com or SE sites. However I can use ssh to log into a server, which I have root access so basically I can do anything I want with it. So I was thinking that maybe I could use that server as a proxy so I can visit sites through it. I tested it using ssh -vT [email protected] which gave a proper response. And In my computer I can't do this. Also I tried downloading something from the gun.org using wget, which can't be done in my computer too. And it succeeded on that server. I don't know if that's enough to say that this server have full access to the Internet. But I assumed so and I installed squid3 on it. After trying some while, I failed to get it working. I got this after I run squid3 -k parse 2012/07/06 21:45:18| Processing Configuration File: /etc/squid3/squid.conf (depth 0) 2012/07/06 21:45:18| Processing: acl manager proto cache_object 2012/07/06 21:45:18| Processing: acl localhost src 127.0.0.1/32 ::1 2012/07/06 21:45:18| Processing: acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 2012/07/06 21:45:18| Processing: acl localnet src 10.1.0.0/16 # RFC1918 possible internal network 2012/07/06 21:45:18| Processing: acl SSL_ports port 443 2012/07/06 21:45:18| Processing: acl Safe_ports port 80 # http 2012/07/06 21:45:18| Processing: acl Safe_ports port 21 # ftp 2012/07/06 21:45:18| Processing: acl Safe_ports port 443 # https 2012/07/06 21:45:18| Processing: acl Safe_ports port 70 # gopher 2012/07/06 21:45:18| Processing: acl Safe_ports port 210 # wais 2012/07/06 21:45:18| Processing: acl Safe_ports port 1025-65535 # unregistered ports 2012/07/06 21:45:18| Processing: acl Safe_ports port 280 # http-mgmt 2012/07/06 21:45:18| Processing: acl Safe_ports port 488 # gss-http 2012/07/06 21:45:18| Processing: acl Safe_ports port 591 # filemaker 2012/07/06 21:45:18| Processing: acl Safe_ports port 777 # multiling http 2012/07/06 21:45:18| Processing: acl CONNECT method CONNECT 2012/07/06 21:45:18| Processing: http_port 3128 transparent vhost vport 2012/07/06 21:45:18| Starting Authentication on port [::]:3128 2012/07/06 21:45:18| Disabling Authentication on port [::]:3128 (interception enabled) 2012/07/06 21:45:18| Disabling IPv6 on port [::]:3128 (interception enabled) 2012/07/06 21:45:18| Processing: cache_mem 1000 MB 2012/07/06 21:45:18| Processing: cache_swap_low 90 2012/07/06 21:45:18| Processing: coredump_dir /var/spool/squid3 2012/07/06 21:45:18| Processing: refresh_pattern ^ftp: 1440 20% 10080 2012/07/06 21:45:18| Processing: refresh_pattern ^gopher: 1440 0% 1440 2012/07/06 21:45:18| Processing: refresh_pattern -i (/cgi-bin/|?) 0 0% 0 2012/07/06 21:45:18| Processing: refresh_pattern (Release|Packages(.gz)*)$ 0 20% 2880 2012/07/06 21:45:18| Processing: refresh_pattern . 0 20% 4320 2012/07/06 21:45:18| Processing: ipcache_high 95 2012/07/06 21:45:18| Processing: http_access allow all I deleted some allow and deny rules and added http_access allow all so that all the request would be allowed.

  • Benchmark MySQL Cluster using flexAsynch: No free node id found for mysqld(API)?

  • Please wait for User Profile Service... on WIndows 7 takes around 1-2 minutes to process

    - by Chris
    When loggging into our domain, after entering account credentials the log in process takes around 1-2 minutes before it gets past the User Profile Service, the rest of the process takes 2-3 secs. This effects all machines running Windows 7 Enteprise 32-bit and is on fairly high spec laptops (SSD drives, i5 2.93Ghz CPU, 4GB memory). Is there any way to speed this up or is this time delay acceptable? Thanks in advance.

  • Troubleshooting an unstable internet connection

    - by Konrad Rudolph
    My MacBook Pro running OS X (10.9, but I had the same problem before) is connected to a Belkin router via WiFi and, using Virgin Media as the ISP, to the internet. The connection is extremely unstable – on some days, I get a ping timeout every few seconds. In addition, some domains seem to suffer general connectivity issues. For instance, I often find that while the youtube.com website loads, none of the videos (which are hosted on a separate domain) do. At other times, videos load but always fail to buffer, even though the actual connection speed is ok, even though I’ve disabled dash playback. Since I’m living in a rented room and the ISP contract isn’t actually mine I’ve got only limited possibilities of addressing the problem. In particular, I have no access to the router configuration and my non tech savvy landlady, while sympathetic, is not in a great hurry to hand the problem over to the ISP’s customer support. What’s more, I seem to be the only person in the house experiencing these problems – but I can imagine that this is simply because I’m the only one who’s using the internet continuously. I’m searching for specific tests that might be able to pinpoint – and ideally solve – the problem. So far all I’ve managed to do is establish that Virgin is routing my traffic in mysterious ways. Here’s an excerpt from traceroute google.co.uk. It’s worth mentioning that the host name doesn’t seem to matter a lot, the trace route is always the same. traceroute: Warning: google.co.uk has multiple addresses; using 62.254.36.148 traceroute to google.co.uk (62.254.36.148), 64 hops max, 52 byte packets 1 (192.168.2.1) 1.112 ms 1.300 ms 2.359 ms 2 10.100.32.1 (10.100.32.1) 11.926 ms 10.217 ms 24.987 ms 3 cmbg-core-1a-ae3-610.network.virginmedia.net (80.1.202.93) 28.809 ms * 66.653 ms 4 popl-bb-1b-ae16-0.network.virginmedia.net (212.43.163.141) 13.759 ms 126.504 ms 20.472 ms 5 nrth-bb-1b-et-010-0.network.virginmedia.net (62.253.175.57) 28.357 ms 16.398 ms 42.387 ms 6 nrth-bb-1c-ae1-0.network.virginmedia.net (62.253.174.110) 27.441 ms 15.622 ms 12.044 ms 7 lutn-icdn-1-ae0-0.network.virginmedia.net (62.253.175.82) 16.678 ms 28.463 ms 28.253 ms 8 * * * 9 * * * 10 * * * ^C If I let it, this goes on until the end of time. It never seems to reach a destination. Is this normal? A friend living in the same town who is also with Virgin Media has a more conventional traceroute output: 7 hops to google.co.uk, all of which send the ICMP TIME_EXCEEDED response. The obvious fix – rebooting the router – doesn’t seem to help. As far as I can tell, the WiFi connection is stable (I can always ping the router) so the problem is further downstream. I’ve tried using an alternative DNS before (OpenDNS) but if anything, this made things worse. In fact, it made all Google services nigh unreachable.
