  • HP UX can not boot from Ignite Tape

    - by Spirit
    We have hp rp2470 server running hp-ux 11.00, with LVM mirroring. As for redundancy we have second rp2470 same hw (same two processors, same ram, same two hdd’s, same number of lan cards). I want to clone first one to the second. For that purpose I am making ignite tape with the following command: make_tape_recovery -x inc_entire=vg00 Ignite tape finishes without problems. When I boot second server from this ignate tape, server is starting to boot, and ignite restore finishes without any errors, only few notes, which are normal. However vmunix is not booting and when restore finishes, it boot to ISL prompt. From this I cannot boot /stand/vmunix. I tried to run recovery shell but no success. When recovery shell ask to do frecover to restore critical files, then I receive error: frecover(5405): unable to open /dev/rmt/0m At first I thought that the problem might be in the difference of the firmware version of the servers: fw version of production server is: Firmware Version 43.50 and fw version of backup server is: Firmware Version 42.19 So i did a fw upgrade of my backup server so that both servers are v43.50, and tried a recovery but again cant boot the system. Next I did another archive tape with -I (Interactive) flag: make_tape_recovery -I -x inc_entire=vg00 and tried recovery with it, again no good. I cannot find any error or warnings on ignite log, and I cannot boot hpux. I am only on ISL prompt. This is what i've noticed on the gsp logs: ************* SYSTEM ALERT ************** SYSTEM NAME: mcnfwim1 DATE: 07/27/2003 TIME: 10:18:49 ALERT LEVEL: 6 = Boot possible, pending failure - action required REASON FOR ALERT SOURCE: 8 = I/O SOURCE DETAIL: 6 = disk SOURCE ID: 0 PROBLEM DETAIL: 0 = no problem detail LEDs: RUN ATTENTION FAULT REMOTE POWER FLASH OFF ON ON ON LED State: Boot Failed.

  • mounting ext4 fs with block size of 65536

    - by seaquest
    I am doing some benchmarking on EXT4 performance on Compact Flash media. I have created an ext4 fs with block size of 65536. however I can not mount it on ubuntu-10.10-netbook-i386. (it is already mounting ext4 fs with 4096 bytes of block sizes) According to my readings on ext4 it should allow such big block sized fs. I want to hear your comments. root@ubuntu:~# mkfs.ext4 -b 65536 /dev/sda3 Warning: blocksize 65536 not usable on most systems. mke2fs 1.41.12 (17-May-2010) mkfs.ext4: 65536-byte blocks too big for system (max 4096) Proceed anyway?

  • Why are my httpd mpm_prefork processes being reaped so quickly?

    - by Dan Pritts
    We've got a system running RHEL6, x64. We are using a local installation of apache 2.2.22 from source. we serve primarily: mod_perl applications (with a local installation of perl 5.16.0) tomcat applications proxied with mod_jk Here is some context; the main question is below. All of this talks to an Oracle backend. We are having issues with Oracle becoming unresponsive. We think this is because we're hitting the maximum process limit in oracle. We've upped the process limit, but now we are hitting memory pressure on the oracle server. We have tons of oracle sessions sitting idle. I can trace a bunch of them back to the httpd processes. We have mod_perl's Apache::DBI start up a new connection to the database with each httpd child that's spawned. We are concerned that these are not always getting closed out properly when the httpd's exit...and the httpd's are exiting very frequently. I know that it would be good to modify the mod_perl applications to use some better form of db connection pooling; we plan to pursue that but would like to solve our immediate problem sooner. So here's the main question. We are using the prefork MPM. The apache child processes are lasting at most a few minutes. Log analysis shows that each one is serving fewer than 50 clients before exiting; the last request each child serves is OPTIONS * HTTP/1.0 on some sort of internal connection; I'm under the impression that this is a "ping" from the master process. I've adjusted the MPM config as follows. I didn't want to raise MinSpareServers too high, because, after all, i'm trying to minimize the number of sessions to oracle. MinSpareServers 5 MaxSpareServers 30 MaxClients 150 MaxRequestsPerChild 10000 Right now we're serving 250-300 requests per minute. We've got 21 httpd's running, the eldest (other than the master, owned by root) being 3 minutes old. This rate of reaping of the apache children really seems excessive. What could be causing it? Apache was built with: $ ./configure --prefix=/opt/apache --with-ssl=/usr/lib --enable-expires --enable-ext-filter --enable-info --enable-mime-magic --enable-rewrite --enable-so --enable-speling --enable-ssl --enable-usertrack --enable-proxy --enable-headers --enable-log-forensic Apache config info: % /opt/apache/bin/httpd -V Server version: Apache/2.2.22 (Unix) Server built: Jul 23 2012 22:30:13 Server's Module Magic Number: 20051115:30 Server loaded: APR 1.4.5, APR-Util 1.4.1 Compiled using: APR 1.4.5, APR-Util 1.4.1 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/opt/apache" -D SUEXEC_BIN="/opt/apache/bin/suexec" -D DEFAULT_PIDLOG="logs/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="logs/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="conf/mime.types" -D SERVER_CONFIG_FILE="conf/httpd.conf" modules are compiled into apache rather than shared libs: % /opt/apache/bin/httpd -l Compiled in modules: core.c mod_authn_file.c mod_authn_default.c mod_authz_host.c mod_authz_groupfile.c mod_authz_user.c mod_authz_default.c mod_auth_basic.c mod_ext_filter.c mod_include.c mod_filter.c mod_log_config.c mod_log_forensic.c mod_env.c mod_mime_magic.c mod_expires.c mod_headers.c mod_usertrack.c mod_setenvif.c mod_version.c mod_proxy.c mod_proxy_connect.c mod_proxy_ftp.c mod_proxy_http.c mod_proxy_scgi.c mod_proxy_ajp.c mod_proxy_balancer.c mod_ssl.c prefork.c http_core.c mod_mime.c mod_status.c mod_autoindex.c mod_asis.c mod_info.c mod_cgi.c mod_negotiation.c mod_dir.c mod_actions.c mod_speling.c mod_userdir.c mod_alias.c mod_rewrite.c mod_so.c One final note - the red hat httpd, apr, and perl packages are all installed, but ldd shows that none of those libraries are linked with the running httpd.

  • MacBook Pro 10.6 losing dns service, network connection still functional if you know the ip address.

    - by Vincent
    MacBook pro connected to a wireless network (not sure about wired) I lose DNS. I still have a functioning connection and as long as I know the ip address of the website, server... for example skype works, ssh name@ipaddress, .... Things can be working properly and then just quit, Once I was im via skype and lost dns skype continued to work. This has happened in multiple locations on private and public networks. What does not work/fix it: Resetting router changing dns server on computer or router connecting to another network removing the airport interface and adding it back flushing dns The only solution seems to be a restart. A solution to this would be great, but any ideas of this to try would be great. Even a sure way to reproduce this would be useful. Maybe related question: But this is most definitely not true for me. "if I refresh enough -- 3 to 4 times --, it will usually pull up the site. " Here are some tests from terminal. Basically this confirms dns in not functioning vmd17:~ vmd$ ping google.com ping: cannot resolve google.com: Unknown host Trace route to google dns, This works vmd17:~ vmd$ /usr/sbin/traceroute -n -w 2 -q 2 -m 30 8.8.8.8 traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 52 byte packets 1 192.168.1.1 5.195 ms 2.519 ms 2 67.172.136.1 31.881 ms 9.177 ms 3 68.85.107.121 12.168 ms 10.003 ms 4 68.86.103.41 12.021 ms 9.594 ms 5 68.86.91.1 16.712 ms 12.837 ms 6 68.86.86.210 29.951 ms 25.826 ms 7 68.86.87.218 29.554 ms 42.894 ms 8 75.149.231.70 68.271 ms 68.362 ms 9 72.14.233.77 141.178 ms 72.14.233.85 82.553 ms 10 72.14.238.243 83.381 ms 82.811 ms 11 72.14.232.213 194.387 ms 72.14.232.215 84.837 ms 12 209.85.253.145 100.294 ms * 13 8.8.8.8 101.689 ms 89.694 ms 208.67.222.22 is the ip address of opendns dns server vmd17:~ vmd$ dig @208.67.222.222 8.8.8.8 ; <<>> DiG 9.6.0-APPLE-P2 <<>> @208.67.222.222 8.8.8.8 ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached vmd17:~ vmd$ dig @208.67.222.222 gogle.com vmd17:~ vmd$ dig @208.67.222.222 google.com ; <<>> DiG 9.6.0-APPLE-P2 <<>> @208.67.222.222 google.com ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached vmd17:~ vmd$ dig @8.8.8.8 google.com ; <<>> DiG 9.6.0-APPLE-P2 <<>> @8.8.8.8 google.com ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached

  • md/raid:md2: cannot start dirty degraded array, kernel panic

    - by nl-x
    After having made use of a remote power switch, my server did not come back online. When I went to the datacenter and reboot the computer on the spot I see the server booting (I see the centos progress bar with running almost all the way to the end) and eventually giving the following messages: md/raid:md2: cannot start dirty degraded array. md/raid:md2: failed to run raid set. md: pers->run() failed ... md/raid:md2: cannot start dirty degraded array. md/raid:md2: failed to run raid set. md: pers->run() failed ... Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init not tainted 2.6.32-279.1.1.el6.i686 #1 Call Trace: [<c083bfbc>] ? panic+0x68/0x11c [<c045a501>] ? do_exit+0x741/0x750 [<c045a54c>] ? do_group_exit+0x3c/0xa0 [<c045a5c1>] ? sys_exit_group+0x11/0x20 [<c083eba4>] ? syscall_call+0x7/0xb [<c083007b>] ? cmos_wake_setup+0x62/0x112 The server runs CentOS and has software raid, and I don't have backups of the raid settings. The only backup I have is of /home and the database dumps. (Glad to at least have those though.) Since the server is an old Dell PowerEdge 1750 with no CD-ROM drive, I have no way of booting the machine from a boot disk. I also remember in the past that the server also wouldn't boot from a bootable USB disk. So the only way I know how to boot the server is to go to the datacenter, pick up the server and take it to the office. Screw open the server. Attach a cdrom drive to an IDE slot on the motherboard. And then boot it. I am hoping you guys could help me avoid this. I have looked a bit through the boot options and I found the following boot options. When CentOS is about to boot and interrupt the boot-countdown: CentOS (2.6.32-279.1.1.el63.i686) CentOS Linux (2.6.32-71.29.1.el6.i686) centos (2.6.32-71.el6.i686) I think the first configuration is the default one, because choosing that gets me to the above mentioned kernel panic. The other ones end with something like "Sleeping forever". I can press 'e' to edit boot commands, press 'a' to modify kernel arguments and press 'c' for grub command line. The command line gives a grub prompt. But I have no idea how to get the system to boot without (trying to) access the dirty partitions. What I want to do is off course: - boot the machine - check hard drive for errors - mark the drive as clean

  • Netcat file transfer problem

    - by thepurplepixel
    I have two custom scripts I just wrote to facilitate transferring files between my VPS and my home server. They are both written in bash (short & sweet): To send: #!/bin/bash SENDFILE=$1 PORT=$2 HOST='<my house>' HOSTIP=`host $HOST | grep "has address" | cut --delimiter=" " -f 4` echo Transferring file \"$SENDFILE\" to $HOST \($HOSTIP\). tar -c "$SENDFILE" | pv -c -N tar -i 0.5 | lzma -z -c -6 | pv -c -N lzma -i 0.5 | nc -q 1 $HOSTIP $PORT echo Done. To receive: #!/bin/bash SERVER='<myserver>' SERVERIP=`host $SERVER | grep "has address" | cut --delimiter=" " -f 4` PORT=$1 echo Receiving file from $SERVER \($SERVERIP\) on port $PORT. nc -l $PORT | pv -c -N netcat -i 0.5 | lzma -d -c | pv -c -N lzma -i 0.5 | tar -xf - echo Done. The problem is that, for a very quick second, I see something flash along the lines of "Connection Refused" (before pv overwrites it), and no file is ever transferred. The port is forwarded through my router, and nmap confirms it: ~$ sudo nmap -sU -PN -p55515 -v <my house> Starting Nmap 5.00 ( http://nmap.org ) at 2010-04-21 18:10 EDT NSE: Loaded 0 scripts for scanning.

The receiver has no firewall, and outbound traffic on that port is allowed on the sender. I have no idea what to troubleshoot next. Any ideas? P.S.: Feel free to move this to SO/SF if you feel it would fit better there.

  • SELF-SOLVED AutoHotkey Function GetMouseTaskbutton need to adapt for 64-bit OS

I'm using it in a routine to auto-activate window by hovering its taskbar button, and also a routine to close inactive window by middle-click on its taskbar button. Works great on my XP machine. The author had stated that the function does work in Vista, but it refuses to work for me in Vista 64-bit, so apparently it is only valid in 32-bit. And I am very new to AHK, and don't know how to adapt it. Unfortunately, my queries at the site sank without a trace. Does anyone have advice for me? I will be most grateful. Thanks.

  • Laptop turning off when fan is spinning hard

    - by Ieyasu Sawada
    My laptop seems to have reach its lifespan. Its an Acer laptop so I guess that's normal. But I'd like to hear your opinions about this. My laptop is only 2 years old. I haven't heard the fan spinning like crazy not until these past 5 months. What I did: Hoping that its just the applications that I have installed that's consume the life of my laptop from the background. I used PC Decrapifier to uninstall some of the things that I don't need. Reformatted my computer but only the primary partition since my files are on the second partition. Bought a cooling pad. None of these works. I noticed the fan spins so hard when: I have a lot of browser tabs open. Full screen mode a flash video that I'm viewing online. Using VLC to watch encoded videos. There's this thing called minicoder http://sourceforge.net/projects/minicoder/ to reduce the size of videos without affecting much of the quality. I'm suspecting that it needs additional software(to make life easier for the hardware) even though the video is working fine in VLC. VLC consumes about 300,000K and above(as seen from task manager) while watching videos (.mkv). The problem: Laptop suddenly turns off when the fan spins like crazy for about 20 minutes. I'm always checking to see if its already too hot(using my fingers to feel the side of the laptop) but its not so I continued watching and then poof! computer turns off. Laptop won't turn on immediately when I turn it on after it turning off by itself. The light for the power goes on but its turns off immediately. I have to wait for about 10-20 seconds before it boots up without problems. So how do I go about this? Is this just normal for Acer laptops after about 2 years of heavy usage (8-12 hours a day)? My usage is heavy but I normally only have a text-editor(sublime) and browser open(chrome). Here's what I got from HW monitor:

  • All my sites are 403 but the server is running. Errors on startup

    - by Craig
    We gave access to a contractor to install a firewall and somehow while he was doing it he fracked something up. Everything went off-line about 24 hours ago and we are effectively out of business until I solve this and the person who messed up the thing is not returning calls. I found a few errors. First, I'm not a server guy - I can look at log files and normally everything runs fine. All 'services' are running according to 1and1 server monitoring and mail is being delivered just fine. The whole thing was off-line until I (probably stupidly) updated the kernel from 6.2 to 6.3 this morning and I got everything back except the http access. All the domains (~200 of them) are returning a 403 error and nothing is recorded in the access log. On every restart I see this error in the messages log file: init: Failed to spawn ttyS0 main process: unable to execute: No such file or directory and a little later these: kernel: WARNING: at kernel/sched.c:5914 thread_return+0x232/0x79d() (Not tainted) kernel: Hardware name: X9SCL/X9SCM kernel: Modules linked in: xt_iprange iptable_filter ip_tables ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables ipv6 ext4 jbd2 serio_raw i2c_i801 i2c_core sg iTCO_wdt iTCO_vendor_support e1000e ext3 jbd mbcache raid1 sd_mod crc_t10dif ahci dm_mirror dm_region_hash dm_log dm_mod [last unloaded: scsi_wait_scan] kernel: Pid: 367, comm: md3_raid1 Not tainted 2.6.32-220.2.1.el6.x86_64 #1 kernel: Call Trace: kernel: [<ffffffff81069997>] ? warn_slowpath_common+0x87/0xc0 kernel: [<ffffffff810699ea>] ? warn_slowpath_null+0x1a/0x20 kernel: [<ffffffff814eccc5>] ? thread_return+0x232/0x79d kernel: [<ffffffff8126a4d9>] ? cpumask_next_and+0x29/0x50 kernel: [<ffffffff813e9c05>] ? md_super_wait+0x55/0x90 kernel: [<ffffffff81090a10>] ? autoremove_wake_function+0x0/0x40 kernel: [<ffffffff813ebf46>] ? md_update_sb+0x206/0x3f0 kernel: [<ffffffff813ee922>] ? md_check_recovery+0x3f2/0x6d0 kernel: [<ffffffffa005b129>] ? raid1d+0x49/0x1050 [raid1] kernel: [<ffffffff814ed985>] ? schedule_timeout+0x215/0x2e0 kernel: [<ffffffff814ef447>] ? _spin_unlock_irqrestore+0x17/0x20 kernel: [<ffffffff813eb336>] ? md_thread+0x116/0x150 kernel: [<ffffffff81090a10>] ? autoremove_wake_function+0x0/0x40 kernel: [<ffffffff813eb220>] ? md_thread+0x0/0x150 kernel: [<ffffffff810906a6>] ? kthread+0x96/0xa0 kernel: [<ffffffff8100c14a>] ? child_rip+0xa/0x20 kernel: [<ffffffff81090610>] ? kthread+0x0/0xa0 kernel: [<ffffffff8100c140>] ? child_rip+0x0/0x20 And something is wrong with the Named/BIND resulting in the same error for all domains: zone DOMAINEXAMPLE.com/IN: loading from master file DOMAINEXAMPLE.com failed: file not found zone DOMAINEXAMPLE.com/IN: not loaded due to errors. _default/DOMAINEXAMPLE.com/IN: file not found I'm pretty sure this is not enough information to solve the problem, but I'm willing to engage someone who can work this out for me.

  • Chrome Problems on Windows 8

    - by Akshat Mittal
    There are a lot of problems with Chrome (24.0.1312.14 beta || But all this happened before update also) on Windows 8. Problems and explanations are listed below: Google Chrome re-draw time: When I switch tabs, the window retains the content of the previous tab and displays that even if I move my mouse, if only refreshes (re-draws) when there is a change on the webpage (like on hover) or I do a select all (or scroll). One thing to note is that the hover and select happens on the real page and not the retained image-like thing of the older webpage. Chrome is slow and laggy: Websites such as Facebook and Twitter (and more) have gone extremely laggy on Chrome (Win 8). When I was using Windows 7, I never experienced a lag or something. Also when using HTML-5 Websites, the transition (the -webkit-transition in CSS) goes extremely slow at times. Plugins Crash: Plugins like Flash Player, Shockwave Player, and more that are in-built into Chrome Crashes a lot, even when doing simple tasks like playing YouTube Videos, displaying ads or something. Chrome Crashes: Chrome has crashed over 100 times in the past month. Google Chrome just crashes randomly or I don't know the reason. Random Page crashes: Chrome results chrome://crash/(Copy-Paste this in address bar) on random pages even when the page is just loaded, I understand that this can happen on heavy HTML5 or JS websites but what about HTML only websites! Most of the things above happens on Super User also, Super User never had any problem when using Chrome on Windows 7. UPDATE 1: @magicandre1981 Commented for trying to disable Hardware Acceleration. I tried it, it somewhat solved the problem but din't fix it. I am still experiencing all the above issues but less frequently (maybe because Chrome Restarted Completely) UPDATE 2: @avirk asked me to try a Stable Version of Chrome and Firefox, I din't experience any lag in Firefox, a little (negligible) lag in Chrome 22 (Maybe because its a new copy of Chrome, I haven't used it much). Is anybody else experiencing such issues? Does anybody has a solution to any of these? Any Help is appreciated! Thank You!

  • What is the best server or Ip address to use for prolonged testing?

    - by eldorel
    I usually run uptime/latency tests against (and from) two servers that we own at different sites and until recently I've used the google dns servers as a control group. However, I've realized there is a potential problem with monitoring latency over extended periods of time. Almost all of the major service providers are using ANYCAST. For short tests this doesn't matter, but I need to run a set of tests for at least a week to try and catch an intermittent problem, and a change in the anycast priority while trying to test latency will cause the latency values for that server to change accordingly. Since I'm submitting graphs of this data to the ISP, I need to avoid/account for as many variables as possible. Spikes in the data for only one of the tested servers will only cause headaches. So can anyone recommend servers that: are not using anycast are owned by an entity that has a good uptime reputation (so they can't claim that the problem is server-side) will respond to ICMP requests Have an available service that runs on TCP/UDP (http or dns preferably) Wont consider an automated request every 10 minutes to be abuse Are accessible from anywhere in the world Are not local to the isp ( consider this an investigation of a hostile party ) Thanks in advance. Edit: added #6 and #7 above. More info: I am attempting to demonstrate a network problem for an entire node of our local ISP's network. They are actively blaming the issue on the equipment installed at the customer sites (our backup site is one of these), and refuse to escalate the problem. (even though 2 of these businesses have ISP provided modems, and all of us have completely different routers/services running) I am already quite familiar with the need to test an isp controlled IP, but they are actively dropping all packets targeted at gateway ip addresses and are only passing traffic addressed beyond the gateways. So to demonstrate the issue, I am sending packets to other systems in the same node, systems one hop away from the affected node, and systems completely outside the network. Unfortunately, all of the systems I have currently are either administered directly by myself, or by people who are biased enough to assist me. I need to have several systems included in the trace/log/graphs that are 100% not in the control of either myself or the isp so that the graphs have a stable/unbiased control group. These requirements are straight from legal, I'm just trying to make sure that everything that could be argued to invalidate the data is already covered. In Summary: I need to be able to show tcp/udp/icmp as 3 separate data points, and I need to be able to show the connections inside the local node, from local node to another nearby node, from those 2 nodes to the internet, and through the internet to both verifiable servers and a control group that I have no control over whatsoever. Again, Google/opendns/yahoo/msn/facebook/etc all use anycast, which throws the numbers off every time the anycast caches expire, so I need suggestions of an IP or server that is available for this type of testing. I was hoping someone knew of a system run by someone such as ISC or ICANN, or perhaps even a .gov server (fcc or nsa maybe?) setup for this type of testing. Thanks again.

  • How to diagnose computer lockups and freezes?

    - by Scott Mitchell
    I built a desktop computer a couple years back with the following specs: CPU: Intel Core 2 Quad Q9300 Yorkfield 2.5GHz 6 MB L2 Cache LGA 775 95W Quad-Core Processor BX80580Q9300 Motherboard: EVGA 122-CK-NF68-T1 LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard Video Card: Two EVGA 256-P2-N758-TR GeForce 8600GT SCC 256 MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card PSU: SeaSonic S12 Energy Plus SS-550HT 550W ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply Memory: Two G.SKILL 4 GB (2 x 2 GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ Since its inception, the machine has periodically locked up, the regularity having varied over the years from once a day to once a month. Typically, lockups happen once every few days. By "lockup" I mean my computer just freezes. The screen locks up, I can't move the mouse. Hitting keys on my keyboard that normally turn LEDs on or off on the keyboard (such as Caps Lock) no longer turn the LEDs on or off. If there was music playing at the time of the lockup, noise keeps coming out of the speakers, but it's just the current frequency/note that plays indefinitely. There is no BSOD. When such a lockup occurs I have to do a hard reboot by either turning off the computer or hitting the reset button. I have the most recent version of the NVIDIA hardware drivers, and update them semi-regularly, but that hasn't seemed to help. I am currently using Windows 7 x64, but was previously using Windows Server 2003 x64 and having the same lockup issues. My guess is that it's somehow video driver or motherboard related, but I don't know how to go about diagnosing this problem to narrow down which of the two is the culprit. Additional information re: cooling Regarding cooling... I've not installed any after-market cooling systems aside from two regular fans I scavenged from an older computer. The fan atop the CPU is the one that shipped with it. One of the two scavenged fans I added it located at the bottom tower of the corner, in an attempt to create some airflow from front to back. The second fan is pointed directly at the two video cards. SpeedFan installation and readings Per studiohack's suggestion, I installed SpeedFan, which provided the following temperature readings: GPU: 63C GPU: 65C System: 76C CPU: 64C AUX: 36C Core 0: 78C Core 1: 76C Core 2: 79C Core 3: 79C Update #3: Another Lockup :-( Well, I had another lockup last night. :-( SpeedFan reported the CPU temp at 38 C when it happened, and there was no spike in temperature leading up to the freeze. One thing I notice is that the freeze seems more likely to happen if I am watching a video. In fact, of the last 5 freezes over the past month, 4 of them have been while watching a video on Flickr. Not necessarily the same video, but a video nevertheless. I don't know if this is just coincidence or if it means anything. (As an aside, each night before bedtime my 2 year old daughter sits on my lap and watches some home videos on Flickr and, in the last month, has learned the phrase, "Uh oh, computer broke.") Update #4: MemTest86 and 3DMark06 Test Results: Per suggestions in the comments, I ran the MemTest86 overnight and it cycled through the 8 GB of memory 5 times without error. I also ran the 3DMark06 test without a problem (see my scores at http://3dmark.com/3dm06/15163549). So... what now? :-) Any further suggestions on what to check? Is there some way to get a stack trace or something when the computer locks like that? Resolution I have never did figure out the particular problems, but based on the suggestions here and elsewhere, I'm presuming it was a motherboard issue. In any event, I recently upgraded my system, buying a new motherbeard, PSU, CPU, and RAM, and that new rig has been working splendidly the past several weeks. I am using the same graphic cards as in the old setup, so I think it's safe to reason that they weren't the cause of the problem.

  • Use windows 7 inside virtual box,as guest i mean, to create a Windows 7 USB using "Windows 7 USB/DVD Download Tool" ? (Linux as host)

    - by Abel Coto
    I want to download the Windows 7 professional iso (x32), from microsoft, and , i can do two things. Or buy a new burner , as mine doesn't work (i am trying to decide what dvd writer i could buy) or use a usb dongle to copy the iso to it , and install it via usb. I want to install Windows 7 in a netbook that now has debian,and in my pc. I think i have to buy only the license for the pc , as the netbook came with windows 7 preinstalled, so i suppose that i can use that serial to activate the windows , although i don't know how to install windows 7 starter instead of professional (i think if you remove a file from the iso, windows let you choose the edition to install). The problem is that in both pcs there isn't any windows , only debian. My father has a netbook with windows 7 starter, but i think it hasn't antivirus (at least until have the Karspersky Internet security for 3 pcs bought ), and i don't trust to make the usb there , if i don't now that there isn't any virus or malware. So i am trying to find a way of Create a Windows 7 usb installation , to at least be able to install windows 7 in the netbook without a external dvd writer. I know that with dd in linux you can copy a debian.iso to the usb , and then install debian with it (i've done it) using something like dd if=win7.iso of=/dev/sdb, but i don't know if this would work for windows 7 iso,and if dd will correctly copy the iso to the usb. I suppose that if you are able to boot and install windows 7 from the usb , is that the method works,and you can forget of problems later with the windows 7 installation (problems because some files could not be copied or like). So , i remembered that Microsoft created a tool to copy the iso to the usb using windows. So i thought that i could install in my pc , virtual box , as i have VT and 8 GB ram in it, and download the iso from microsoft ,install windows 7 in the virtual machine , and then copy the iso inside the machine , donwload the iso tool, and atach a usb to the pc, connect it to the guest , and use the tool to copy the iso to the USB. But i don't now if is possible to use a virtual machine to do this , or the virtualization could give problems with the usb, or something. I have found some minutes ago this How to make a windows 7 usb flash install media, from linux? The first method (dd) is the one i like more , and i trust more ( i don't now if the second method using ms-sys , works well , and if i can trust it. I understand that a iso is like a .rar , but no compressed,only containing the files ,so mount the iso and cp the data inside perhaps is ok. Although the method i like more is the microsoft one (more because is from microsoft , and i suppose they now what they do ,at least with this usb related thing, than anything). Perhaps worth more to buy a external dvd writer haha ... Should the virtual machine method work ?

  • Why Photoshop CS5's photomerge's result immediately disappear?

    - by koiyu
    I have a bunch of JPG-files which I want to stitch together with Photoshop's Photomerge function. I choose File → Automate → Photomerge... and browse for the files. Photoshop opens the files and starts analyzing. I see the process bar filling and different phases are mentioned on the process bar. Nothing weird there. When the merging is done (and if I don't blink my eyes), I can see layers-palette is populated with the chosen files and, by quickly judging from the layer thumbnails, they're properly aligned. Sometimes the image window itself can be seen, but not always. Problem is that the layers and the image disappear in a flash. There is no error message. Everything is like prior starting the photomerge. No file has been changed. I could continue to use Photoshop normally. This is what I've tried so far: Loaded folder which has 38 JPG images, 4272 x 2848 and ˜ 5 megabytes per file Loaded the same files, but chose Use Files instead of Use Folder in the photomerge's window Loaded 19 JPG images, 4272 x 2848 and ˜ 5 megabytes per file Loaded 10 JPG images, ⇑ see above Loaded 5 JPG images, see above Loaded 3 JPG images, see above Scaled the images to 2256 x 1504 and ˜< 1 megabytes per file Loaded in a set of 38, 19, 10, 5, 3 Following steps are tested with these smaller files and with a set of 5 images Read Adobe's forums and reduced the amount of RAM Photoshop uses gradually from ˜ 80 % to 50 % (though I didn't understand the logic behind this) Would've reduced cache tile size to 128K, but it was set so already Disabled OpenGL Scaled the images to 800 x 533 and ˜ 100 kilobytes per file, loaded a set of 5 Read more unanswered threads around the internet In between each test I closed and reopened Photoshop. This is the first time I've even tried using photomerge. Am I doing something wrong? How can I locate what is the problem? How do I fix this? Photoshop is 64 bit Extended CS5 version. I'm on a mid-2010 quad-core (i5) iMac with up-to-date Mac OS X 10.6.6. Edit: Weird. First loading the images into one file via File → Scripts → Load Files into Stack… and then using Edit → Auto-Align Layers…, which, effectively, is the same as photomerge (even the dialog looks kind of the same), works! Even with the original JPGs without any issues. This doesn't fix photomerge, though.

  • duplicate cache pages: Varnish

    - by Sukhjinder Singh
    Recently we have configured Varnish on our server, it was successfully setup but we noticed that if we open any page in multiple browsers, the Varnish send request to Apache not matter page is cached or not.

  • IPv6 host route is deleted after PMTU expires

    I am experimenting my new IPv6 tunnel setup between my local Ubuntu box and a scratch Linode. I set up some docker containers, configured 6in4 tunnel server and IPv6 forwarding on the Linode: # uname -a Linux argo 3.15.4-x86_64-linode45 #1 SMP Mon Jul 7 08:42:36 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux # ip addr .. snipped .. 48: sit-sapikachu: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1472 qdisc noqueue state UNKNOWN group default link/sit 106.185.41.115 peer 1.2.3.4 inet6 fd00::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::6ab9:2973/64 scope link valid_lft forever preferred_lft forever 13: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default link/ether 56:84:7a:fe:97:99 brd ff:ff:ff:ff:ff:ff inet 172.17.42.1/16 scope global docker0 valid_lft forever preferred_lft forever inet6 fc00::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::5484:7aff:fefe:9799/64 scope link valid_lft forever preferred_lft forever // Docker containers are bridged to docker0 On my local box, I configured a 6in4 tunnel interface to connect to the Linode box, and added a host route to one of the docker container: # uname -a Linux sapikachu-netbox 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux # ip addr .. snipped .. 16: sit-argo: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1480 qdisc noqueue state UNKNOWN group default link/sit 0.0.0.0 peer 106.185.41.115 inet6 fd00::2/64 scope global valid_lft forever preferred_lft forever inet6 fe80::a97:302/64 scope link valid_lft forever preferred_lft forever inet6 fe80::ac19:1/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:1f0/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:1fa/64 scope link valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether *** brd ff:ff:ff:ff:ff:ff .. snipped .. inet6 fd00:0:1::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::2e0:6fff:fe0e:365e/64 scope link valid_lft forever preferred_lft forever # ip route replace fc00::1875:8606:d8c1:8a9d via fd00::1 # Add route to docker container # ip -6 route .. snipped unrelated routes fc00::1875:8606:d8c1:8a9d via fd00::1 dev sit-argo metric 1024 expires 590sec mtu 1472 fd00::/64 dev sit-argo proto kernel metric 256 fd00:0:1::/64 dev eth0 proto kernel metric 256 fe80::/64 dev sit-argo proto kernel metric 256 (Note that tunnel MTU on my local box is different from the server, this is intentional for testing) After adding the host route to the docker container (fc00::1875:8606:d8c1:8a9d), I can ping the container without problem until the route expires. After that I couldn't get reply any more. If I run ip -6 route in a few seconds after expiration, expiration time of the host route will be a negative number: fc00::1875:8606:d8c1:8a9d via fd00::1 dev sit-argo metric 1024 expires -1sec And output of ip route get fc00::1875:8606:d8c1:8a9d shows that it is routed to my default IPv6 gateway (which fails to route it correctly of course, since the address is not globally routable). After some time, the host route disappears without a trace. This problem won't happen if I do either one of the following things: Set MTU of tunnel on my local box to be the same as the server (1472). The route won't have expiration time in both ip -6 route and ip route get in this case. Instead of adding a host route, add a route with network mask (even /127 works). In this case ip -6 route shows the route without expiration time, ip route get shows expiration time but it will be correctly refreshed after expiration. Although this problem can be easily resolved, I am curious to know why this happens. Is there error in my configuration, or is this a kernel bug?

  • amplified reflected attack on dns

    The term is new to me. So I have a few questions about it. I've heard it mostly happens with DNS servers? How do you protect against it? How do you know if your servers can be used as a victim?

  • Model M Keyboard inputs incorrect characters after logging in to Fedora

    - by mickburkejnr
    I recently bought a 24 year old IBM Model M keyboard. From what I gather, it'd been left on a shelf for the last 5 years, so you can imagine the amount of dust dirt and crap that was on it. Before cleaning it, I plugged it in to my laptop (running Fedora 17) using a PS/2 to USB adapter. What I found was, while it still works, the keys I press don't correspond to what is displayed on the screen. So for example, when I type S on the keyboard, I get ß display on the screen instead. At the time, I put this down to the adapter not working properly. Since then, I stripped the keys off the keyboard and cleaned the whole thing. It looks like it's just come out of a box! I then plugged it in to my computer (also running Fedora 17) via a standard PS/2 plug. The computer loaded up to the login screen, and I typed in my password. Pressed enter, and I logged straight in to my machine. At this point, I opened up a text editor and started typing some stuff. To my horror, the keystrokes I was entering weren't coming up as intended. What came up instead were characters that would map to the pressed key but only under a different keyboard language setting. I opened up a program to see what keyboard language had been selected, and the correct one for the keyboard was selected (which is UK in my case). I opened up a window that would show what characters mapped to what keys, and I pressed every single key on the keyboard, and every corresponding block representing each key lit up. I went back to the text editor to try again, but I was still getting these random characters. Whats more is that the backspace key would not work, although in the other utility it would flash when pressed. What I know is that at the login screen the keyboard must have entered the correct characters, otherwise I wouldn't have been able to log in. Further more, keys that don't respond while using a text editor as sending signals to the computer, as illustrated in that keyboard utility. The question is why random characters are displayed when they really shouldn't be? Would this be a hardware fault or a software issue?

  • How to run a restricted set of programs with Administrator privileges without giving up Admin acces (Win7 Pro)

    - by frLich
    I have a shared system, running Windows7 X64, restricted to a 'standard user' with no password. Not everyone who has access to the system has the administrator password. This works rather well, except for some applications - specially the unlock-applications for encrypted hard drives/USB flash drives. The specific ones either require Administrator access (eg. Seagate Blackarmor) or simply fail without it -- since these programs are sending raw commands to a device, this is to be expected. I would like to be able to add the hashes of these particular programs to a whitelist, and have them run as administrator without needing any prompts. Since these are by definition on removable media, I can't simply use a filename or even a path. One of the users who shares the system can be considered 'crafty', so anything which temporarily grants administrator rights to an user account is certain to cause problems. What i'd like to be able to do: 1) Create an admin account that can only run programs from a whitelist (or, failing that, from a directory) I can't find a good way to do this: As far as I can tell, SRP applies equally to ALL users? Even if I put a "Deny" token on all directories on the system, such that new directories would inherit it, it could still potentially run things from the mounted USB devices. I also don't know whether it's possible to create a new directory that DOESN'T inherit from the parent, that would lake the deny token, and provide admin access. 2) Find a lightweight service that will run these programs in its local context Windows7 seems to block cross-privilege level communication by default, and I haven't found such for windows 7. One example seems to be "sudo" (http://pages.cpsc.ucalgary.ca/~nfriess/sudo/) but because it uses a WLNOTIFY hook, it won't work under Vista nor Windows7 Non-Solutions: - RunAs: Requires administrator password! (but everyone calls it "sudo" anyway) - RunAs /savecred: Nice idea, but appears to be completely insecure. - RUNASSPC - Same concept as RunAs, uses "encrypted" files with credentials, but checks in user-space. - Scheduled Tasks - "Fixed" permissions make this difficult, and doesn't support interactive processes even if it did. - SuRun: From Google: "Surun uses its own Windows service that adds the user to the group of administrators during program start and removes him automatically from that group again"

  • Successfully concatenating multiple videos

    - by wiseguydigital
    My mission is to create videos out of old web slideshows. To start with I have jpegs and audio files that worked as Flash slideshows in an old system, structured such as this: Audio structure my_audio_1.mp3 (this file is a 3 second mp3 of silence) my_audio_2.mp3 my_audio_3.mp3 my_audio_4 etc... roughly 30 mp3s per slideshow Image structure my_image_1.jpg (this acts as the opening slide) my_image_2.jpg my_image_3.jpg my_image_4. etc... roughly 30 images per slideshow. As there are almost 100 slideshows that must be converted to video, I have created a web-based interface using PHP to automate the process, that sits on a local system and attempts to combine the files using shell_exec(). The process uses the following workflow: Loop through each slide and make an avi or mpeg. So for instance my_mini_video_2.avi would be a video that consists of my_image_2.jpg and has a soundtrack of my_audio_2.mp3. This slide would last the length of my_audio_2.mp3. Join / stitch / concat all of the mini videos to create the final video (Using a combination of cat and either mencoder or ffmpeg (I have also tried avimerge but to no avail). Transcode the new 'master' video to various formats such as flv etc. I thought this would be simple and have been close on many occasions but it still won't work. I can't get past stage 2 as I can't get a perfect 'master' video. I have now experimented with Mencoder, FFMpeg and seem to have been through every combination I can think of. The problem is that the audio and visuals never sync, no matter what I try. Also, I have even tried created audio-less mini videos, joining the MP3s into one long MP3 using both cat and mp3wrap and then assigning the new long MP3 as the audio track, but this always produces either a very short file or a badly slowed down file and makes the female voiceover sound like a male boxer!!! There appears to be no problems at all with the original files. Does anybody have any experience in producing a video successfully from the same kind of starting point? Or any ideas on what I may be doing wrong? As an example: If I create silent mini-videos, and stitch them together into 'temp-master.mpg' and then join the MP3s together into single MP3 called 'temp-master-audio.mp3', the audio file's duration is 09:10 and the video file's duration is 08:35. They should be the same and the audio will seem sloooow. I haven't posted code as I have written lots and lots of combinations.

  • VLAN issues between linux kernels 2.6 / 3.3 in an ESX / Cisco environment

    - by David Griffith
    I shall attempt to explain an issue I have encountered - I have a VM running on esx 4.1 with an interface connected to VLAN800 via an access port on a cisco 3750. It runs linux - kernel 2.6.24, and has about 5 to 10 Mbit of chatter on 10.10.0.0/16 and various multicast addresses to look after. I needed to isolate certain devices from certain other devices on the network, with all of them having to talk to that one VM. No, the address space can't be separated, nor can the networks be easily vlan'd apart. The software on the VM listens to one interface only. Private vlans appear to be the way to go. So as a test, I built a bridge on the VM that globs together the vlans as needed. All good, everything works as expected. But occasionally (sigh) there's some latency that trips up a couple of profinet devices on the network because, you know, you're not really supposed to trunk real-time protocols around the place willy-nilly. I shift it to our test/backup server - works nicely, but I don't want it to be running on the test server as we muck around with that a lot. So I says to myself, "I'll put it on a new VM for testing and tweaking." I download a small linux distro with kernel 3.3, and install as a new VM with a the vlans as separate interfaces for testing. I power up the testing VM - ok. I bring up all the separate interfaces - ok. I can ping the production VM, see all sorts of traffic going past with tshark, etc. I build a bridge and put the primary vlan on it - the production VM running 2.6 immediately loses its multicast traffic - Unicast is fine. (?) I shut down the bridge - still no multicast traffic (!?) I power-cycle the production VM(!?!?) - multicast traffic returns. I trunk everything into the testing VM and create vlan interfaces under linux instead - same result, as soon as I start the bridge.... no multicast on the production VM. Ok, so I take a break and leave things alone. I decide to play with a couple of ubiquiti bullet radios - I'm testing various firmware as a side project. I flash a radio with Open-wrt-12.09. I enable a trunk on a port on a cisco on our network so I can muck around with multiple vlans and SSIDs I power up the radio and connect - ok. I create a vlan interface from the trunk.... the same vlan as the production VM wayyyyy over there, three cisco routers away. Ok. I bridge the vlan interface to the wifi interface and immediately get a phone call. The production VM has (suprise!) lost its multicast traffic. Again, nothing comes back until I power-cycle the VM. What the hell is going on?

  • Possible HDD malfunction. Need help in diagnosing

    - by Protheus
    Today when using my PC as I did for almost 4 years I experienced the following: during opening new tab in Opera browser screen froze. Music (AIMP 3) continued to play for about 5 minutes and then stopped too. I tried Ctrl+Alt+Del, but win7 lock screen didn't appear. Caps\Scroll or Num locks didn't switch diodes on keyboard. I rebooted my PC and saw that BIOS suggests me to enter it's settings or load by default. I chose default. It don't see proper boot device (old faitful "insert proper boot" something). After second reboot it said that there is no ExpressGate installed (which i turned off in BIOS years ago). I went into BIOS setting to turn off ExpressGate and see configs: time was not set off, all hard drives present, temp and O.C. settings are nominal (no O.C.) I've inserted my Win7 install disk to try recovery. It did load awfully long (about few minutes) and didn't see current installation. PC was utilized in 24/7 mode for almost all these years. Hardware configuration: ASUS P5Q WS Core 2 Quad Q9300 (2.5GHz no O.C.) MSI geForce GTX 460 4x2 Gb GeIL EVO 2 (AFAIR) Seagate something 750Gb (4 years as system HDD 24/7) WD 1Tb (for random stuff, 5 y.o.) Hitachi 500Gb (for even more random stuff, 6 y.o.) NEC DVDRW (ALL DISKS ARE SATA) Cooler Master Silent Pro 700W Software: Windows 7 AND Kubuntu on the same drive with GRUB loader. Sorry I can't remember HDDs and can't see them right now, but I think their models aren't relevant anyway. My idea is that due to some system error or hard drive glitch i've wrecked my primary HDD's MBR. Nevertheless I don't exclude the possibility of other failure. May it's be that motherboard or it's SATA controller? Doubt it, because all drives are seen in BIOS and I could load from DVD. Maybe GRUB got bugged somehow, although I don't see how it's possible from Windows. But I did install KUbuntu from Windows (i wasn't myself then), maybe GRUB did write itself in some windows partition and got rewriteen in process? Right now I am at work with my flash drive with me and I need some advice how to fix MBR or to hear if it's not MBR. I'm going to buy new HDD (Hitachi 7k2000) because I think that my current HDD is compromised and it's unsafe to use it as system drive, especially 24/7.
