• Firefox not using Kerberos despite being configured to

  - by Nicolas Raoul

  I am deploying Linux/Firefox on a corporate Kerberos network. I followed this Kerberos-on-Firefox procedure but still Firefox does not connect via the company's Kerberos. I am using Firefox 3.0.18 on RedHat EL Server 5.5 Here is what I did: Run kinit on the command line to create a Kerberos ticket Check with klist: the ticket is valid until tomorrow, service principal is krbtgt/[email protected]. In Firefox, set network.negotiate-auth.trusted-uris and network.negotiate-auth.delegation-uris to .dc.thecompany.com. Load the company's portal page via its full hostname: http://server37.thecompany.com/alfresco. (note: server37 is actually the machine I am running Firefox on, but that should not be a problem I guess) PROBLEM: the company's intranet portal still serves me the login/password page. The same portal correctly uses Kerberos on Internet Explorer/Windows 7 machines, same settings, and shows the user's personal page. The server does not see any Kerberos request coming. Did I do something wrong? I enabled NSPR_LOG_MODULES=negotiateauth:5 as explained here, but the log file stays empty.

• Oracle 10g for Windows does not start up on system boot

  - by Mike Dimmick

  We have an Oracle 10g Enterprise Edition installation (10.2.0.1.0) on a Windows Server 2003 virtual machine. It was initially created with Virtual Server 2005 R2 SP1 but has now been migrated to Windows Server 2008 Hyper-V. The services start on system boot, but the instance does not start up. This problem was actually occurring on Virtual Server after a migration from one server to another, but I managed to fix it then with: oradim -edit -sid ORCL -startmode auto However, this now has no effect. oradim.log (in %OracleHome%\database\oradim.log) says: Thu Jun 10 14:14:48 2010 C:\oracle\product\10.2.0\db_3\bin\oradim.exe -startup -sid orcl -usrpwd * -log oradim.log -nocheck 0 Thu Jun 10 14:14:48 2010 ORA-12560: TNS:protocol adapter error sqlnet.log in the same folder has: Fatal NI connect error 12560, connecting to: (DESCRIPTION=(ADDRESS=(PROTOCOL=BEQ)(PROGRAM=oracle)(ARGV0=oracleorcl)(ARGS='(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))'))(CONNECT_DATA=(SID=orcl)(CID=(PROGRAM=C:\oracle\product\10.2.0\db_3\bin\oradim.exe)(HOST=ORACLE-VM)(USER=SYSTEM)))) VERSION INFORMATION: TNS for 32-bit Windows: Version 10.2.0.1.0 - Production Oracle Bequeath NT Protocol Adapter for 32-bit Windows: Version 10.2.0.1.0 - Production Time: 10-JUN-2010 14:14:48 Tracing not turned on.

The problem also occurs when stopping and restarting the OracleServiceORCL service. I've enabled SQL*Net tracing which shows: [10-JUN-2010 15:09:33.919] snlpcss: entry [10-JUN-2010 15:09:34.419] snlpcss: Unable to spawn Oracle oracle (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq))) orcl, error 2.

Right now I have a horrible hack where I've created a Scheduled Task to run oradim -startup -sid ORCL when the Administrator account logs on, and set the VM to auto-logon. I'd still like to work out why it's not working.

• Java VM problem in OpenVZ

  - by Ginnun

  Hi, I bought a vps for hosting my java needs. But I can't run java on it. Everything about java is correctly installed but when I try to run java ("java -version" forexample) I get this error : Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I don't think this is a java centered problem, Out of memory for sure. I contacted the vps admin, but he says everything is fine, you have 2gb ram, expandable to 4gb! I did a bit search on the subject, here is my BEANS file (numbers converted to humanredable form using a script). By the way do JVM heap memory allocs count on kmemsize or privvmpages ? How much ram does that configuration allows me to allocate with jvm for a single process? resource held maxheld barrier limit failcnt kmemsize 2.25 mb 2.35 mb 13.71 mb 14.10 mb 0 lockedpages 0 0 1024.00 kb 1024.00 kb 0 privvmpages 20.54 mb 21.33 mb 256.00 mb 272.00 mb 156 shmpages 5.00 mb 5.00 mb 84.00 mb 84.00 mb 0 numproc 13 14 240 240 0 physpages 9.36 mb 9.45 mb 0 MAX_ULONG 0 vmguarpages 0 0 132.00 mb MAX_ULONG 0 oomguarpages 9.36 mb 9.45 mb MAX_ULONG MAX_ULONG 0 numtcpsock 3 3 360 360 0 numflock 3 3 188 206 0 numpty 2 2 16 16 0 numsiginfo 0 1 256 256 0 tcpsndbuf 69.17 kb 69.17 kb 1.64 mb 2.58 mb 0 tcprcvbuf 48.00 kb 48.00 kb 1.64 mb 2.58 mb 0 othersockbuf 6.80 kb 6.80 kb 1.07 mb 2.00 mb 0 dgramrcvbuf 0.00 kb 0.00 kb 256.00 kb 256.00 kb 0 numothersock 9 10 360 360 0 dcachesize 0.00 kb 0.00 kb 3.25 mb 3.46 mb 0 numfile 704 746 9312 9312 0 numiptent 10 10 128 128 0 Thanks in advance!

• UAE and the mysteries of unreachable websites

  - by 0plus1

  I write here because I'm really lost, please stay with me because it's not easy to explain. A company asked me to set-up a private server, now I'm a programmer so I got a solution with technical support and cpanel which helped me to setup everything and it's working smoothless. I'm by no means a professional sysadmin, but I have a fair knowledge of server configurations, but this problem is way over my knowledge, and apparently way over the knowledge of most sysadmins, I really hope that here I'll find someone with enough experience to help me or at least give me more insight. Now this company for which I'm consulting operates in the UAE (United Arab Emirates) and from there the server is almost unreachable. It started with ns not registering in the UAE, after a week that sorted itself out and now the site is indeed reachable, but it takes almost 2 minutes to load a webpage with one line of text. Emails go in timeout. The domain currently parked there has been bought appositely for tests, the main one that was supposed to go there, after a catastrophic week has been transferred to a shared hosting solution in the UK, and from there it works like a charme. Now after doing some research I discovered that I'm not alone in this, there are several reports of webmasters discovering that their website is not reachable inside the UAE, and mind this has nothing to do with the state-wide block of questionable sites, because in that case an error message appears, this seems to be related to the infrastructure of the UAE, which apparently reroutes everything through their own "fake" internet. Apparently new servers with their own IP are not recognized (yet?) by the UAE infrastructure, while shared hosting solutions seeing that they operates tons of other websites are more likely to be part of the UAE network. Now my questions are: 1) Has someone a real explanation for this? The only thing I can think of is that the server is on a new IP that is not yet recognized by the UAE, but that doesn't explain why it loads (even if after 2 minutes). I don't have any help from within the UAE as the only people that are "experts" are questionable companies that simply try to sell their own services. 2) If there is really some kind of block of new servers, is it possible to know before if a server is reachable from within the UAE, currently this is not a ns problem as even accessing the server with its IP result in a 2 minute wait. 3) Can it be that the problem lies somewhere else? There are some tests that I can perform? I'm not physically in the UAE, but I can ask the people there, or use teamviewer. Could it be some misconfiguration on the server (mind that the site works EVERYWHERE else in the world). Thank you for ANY kind of help

• My linux server "Number of processes created" and "Context switches" are growing incredibly fast

  - by Jorge Fuentes González

  I have a strange behaviour in my server :-/. Is a OpenVZ VPS (I think is OpenVZ, because /proc/user_beancounters exists and df -h returns /dev/simfs drive. Also ifconfig returns venet0). When I do cat /proc/stat, I can see how each second about 50-100 processes are created and happens about 800k-1200k context switches! All that info is with the server completely idle, no traffic nor programs running. Top shows 0 load average and 100% idle CPU. I've closed all non-needed services (httpd, mysqld, sendmail, nagios, named...) and the problem still happens. I do ps -ALf each second too and I don't see any changes, only a new ps process is created each time and the PID is just the same as before + 1, so new processes are not created, so I thought that process growing in cat /proc/stat must be threads (Yes, seems that processes in /proc/stat counts threads creation too as this states: http://webcache.googleusercontent.com/search?q=cache:8NLgzKEzHQQJ:www.linuxhowtos.org/System/procstat.htm&hl=es&tbo=d&gl=es&strip=1). I've changed to /proc dir and done cat [PID]\status with all PIDs listed with ls (Including kernel ones) and in any process voluntary_ctxt_switches nor nonvoluntary_ctxt_switches are growing at the same speed as cat /proc/stat does (just a few tens/second), Threads keeps the same also. I've done strace -p PID to all process too so I can see if any process is crating threads or something but the only process that has a bit of movement is ssh and that movement is read/write operations because of the data is sending to my terminal. After that, I've done vmstat -s and saw that forks is growing at the same speed processes in /proc/stat does. As http://linux.die.net/man/2/fork says, each fork() creates a new PID but my server PID is not growing! The last thing I can think of is that all process data that proc/stat and vmstat -s show is shared with all the other VPS stored in the same machine, but I don't know if that is correct... If someone can throw some light on this I would be really grateful.

• Using my old PC as a web/file server?

  - by Garrett

  I have an old desktop computer that I've been trying to sell for AGES. I guess nobody is looking for computers because it was advertised at a dirt cheap price on craigslist, local papers, etc. Anyways, I was wondering if it would be worth it to set it up as a home file server, a web dev server (I have a web host for actual production use), and maybe host a few server applications (ex: ventrillo). The computer is actually an old Dell that I cannibalized after the motherboard being destroyed by lightning, so it has fairly new parts in it. The specs are: P4 3.4GHz w/ HT and Artic Cooling Freezer 7 3GB DDR2 533 RAM 80GB hdd (will upgrade the hard drive if it's even worth using as a server) basic dvd rom 430 Watt Thermaltake PSU (it might be important to note that it is only 60% efficiency) ATI Radeon x600 256MB Antec 300 case It's not a really beefy machine, I just can't see giving it away or putting it in the corner to just collect dust. I have Windows Server 2008 R2 Standard and I am confident in my skills in operating most Linux operating systems. I'd also be using it to tinker with when I learn new things in my server admin classes (I'm finishing my 2nd year in college at the moment so I'm still learning) Also, my house is quite old and the electrical wiring is pretty poor (it MIGHT be up to code, then again, where I live most people don't even know what regulations are or let alone know how to spell it...) Would it be safe to leave it running all day and is it going to run up my electric bill because of the PSU efficiency? I only have 5mbit cable internet, but I won't be running very bandwidth intense services on it so it should be ok. I should elaborate on why I am concerned about the power. The circuits should be fine, but I'm more concerned about fire hazard. What is the likelihood that the server could cause an electrical fire? Again, thank you all for the feedback!

• Copying compressed files from Server 2008 R2 network share to XP client via VPN fails

  - by Dejan Janjuševic

  At the first sight the question looks similar to this one. I have experienced an odd behavior while trying to copy a certain file from Windows Server 2008 R2 network share to Windows XP Professional client via VPN. The VPN was set up using RRAS on the server machine. I will try to provide as much informations as possible in order to make the issue more clear. When trying to copy the compressed file sized ~2.5 MB (via Explorer or CMD, doesn't matter), the process stalls after some 20%, producing an error message after few seconds: Cannot copy filename: The specified network name is no longer available. If i start the command ping -t 192.168.2.1 (where the IP address specified belongs to the server) side by side with the copy command, I can clearly see that the ping command times out for few seconds as the copy process stalls. When this happens all network activities are frozen. After a few seconds, the network recovers, ping continues to run normally, however the copy process stands still before it displays the above error message. Copying other files (I tried 4-5 files), of which some are larger and some are smaller, succeeds. Seems to me that I can copy all uncompressed files. As soon as I try to copy an archive, the process freezes. Even a 707 KB large archive can't be copied. I can only reproduce this behavior on 2 machines, both Windows XP Professional, one is w/ SP2 and the other w/ SP3. Other XP clients don't have this problem, neither do Windows 7 clients. If I connect to the server using Remote Desktop Connection without using VPN from either of these 2 machines (using the same user account), I can copy anything I want normally, even these "problematic" files. Does anyone have any clue about what could possibly be going on?

• KVM and JBoss Java Application Server

  - by Jason

  We have a large Xen deployment running on both RHEL and CentOS and have recently started looking at KVM since this is where it looks like the future of VM's are on Linux. We can load the server and get everything running without an issue. However when we load up a new one with JBoss (4.2 Community edition, Sun JDK 6) and load a large EAR the server goes a little crazy. The %sy will jump to 80-99% and just hang for large periods of time we see a similar jump in %us on the host machine. We though at first this might be I/O as it seems to happen at start of JBoss but then would "cool down" after everything got loaded. We did some tests by extracting some large tar.gz files and using jar -xvf on the ear but could not re-create. Then we starting thinking this might be some type of memory access issues. We loaded a c-program that would generate a lot of memory activity and sure enough we saw the spikes again. Not as high mind you but we did see it jump. We then wrote a small java program to do the same thing and sure enough we saw it jump again. Any thoughts on what might be causing this? Is this just the way KVM works? As a side note we do NOT see this behavior on any other setup. Xen, VMWare and/or native iron. The system does seem a bit slower than our Xen / VMware ones.

• Traffic shaping on Linux with HTB: weird results

  - by DADGAD

  I'm trying to have some simple bandwidth throttling set up on a Linux server and I'm running into what seems to be very weird stuff despite a seemingly trivial config. I want to shape traffic coming to a specific client IP (10.41.240.240) to a hard maximum of 75Kbit/s. Here's how I set up the shaping: # tc qdisc add dev eth1 root handle 1: htb default 1 r2q 1 # tc class add dev eth1 parent 1: classid 1:1 htb rate 75Kbit # tc class add dev eth1 parent 1:1 classid 1:10 htb rate 75kbit # tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip dst 10.41.240.240 flowid 1:10 To test, I start a file download over HTTP from the said client machine and measure the resulting speed by looking at Kb/s in Firefox. Now, the behaviour is rather puzzling: the DL starts at about 10Kbyte/s and proceeds to pick up speed until it stabilizes at about 75Kbytes/s (Kilobytes, not Kilobits as configured!). Then, If I start several parallel downloads of that very same file, each download stabilizes at about 45Kbytes/s; the combined speed of those downloads thus greatly exceeds the configured maximum. Here's what I get when probing tc for debug info [root@kup-gw-02 /]# tc -s qdisc show dev eth1 qdisc htb 1: r2q 1 default 1 direct_packets_stat 1 Sent 17475717 bytes 1334 pkt (dropped 0, overlimits 2782 requeues 0) rate 0bit 0pps backlog 0b 12p requeues 0 [root@kup-gw-02 /]# tc -s class show dev eth1 class htb 1:1 root rate 75000bit ceil 75000bit burst 1608b cburst 1608b Sent 14369397 bytes 1124 pkt (dropped 0, overlimits 0 requeues 0) rate 577896bit 5pps backlog 0b 0p requeues 0 lended: 1 borrowed: 0 giants: 1938 tokens: -205561 ctokens: -205561 class htb 1:10 parent 1:1 prio 0 **rate 75000bit ceil 75000bit** burst 1608b cburst 1608b Sent 14529077 bytes 1134 pkt (dropped 0, overlimits 0 requeues 0) **rate 589888bit** 5pps backlog 0b 11p requeues 0 lended: 1123 borrowed: 0 giants: 1938 tokens: -205561 ctokens: -205561 What I can't for the life of me understand is this: how come I get a "rate 589888bit 5pps" with a config of "rate 75000bit ceil 75000bit"? Why does the effective rate get so much higher than the configured rate? What am I doing wrong? Why is it behaving the way it is? Please help, I'm stumped. Thanks guys.

• Convert a cassette tape recording to digital format

  - by Optimal Solutions

  Has anyone been successful with transferring audio cassette tape recordings to a digital format? I would like to preserve old cassette tape recordings of my grandparents to some digital format: MP3, WAV, etc... The quality of the tapes are mediocre. I think I can handle the quality restoration but getting the audio from tape to digital is my question. Below is a list of the hardware that I can work with: Cassette Deck: I have a Technics stereo cassette deck model RS-B12. It has separate left and right IN and OUT RCA type jacks on the back. In the front it has a headphone phono jack, plus left and right mic input phono jacks. On the computer side: -I have a Windows Vista PC with no additional software other than what came with the machine from Costco. No sound editing software that I can see. There is no sound card on the PC. On the front panel there is a mini-phono mic input jack and there are several different types of in/out mini-phono jacks on the back. In addition, USB and Firewire. I also have access to a new (2009) iMac with a mini-phono input jack for a powered mic or other audio source and GarageBand that has come with the computer. In addition, USB and Firewire. What are my options for getting these cassette recordings into a digital format? Whats the best format? What sort of wires would I need and will I want to utilize the USB or Firewire or can I simply use the audio inputs on the PC (or Mac) to receive the audio stream?

• Hyper-V VM Lab + RRAS + RDP

  - by Dennis Evans

  My background is primarily .NET Development with some System Administration skills. I'm trying to set up a VM Lab for me to test System Applications I'm developing but I've only ever done System Administration in already set up environments; I've never set up my own. My current setup: Server 2008 R2 Hyper-V Host on physical machine (only role enabled) with two NICs. First NIC dedicated for Management w/ DHCP address from company's network. Second NIC dedicated to RRAS VM w/ DHCP address from company's network. RRAS VM has two NICS, one is virtual private internal only NIC w/ static entry. The other is the physical NIC mentioned above. I've joined it to my VMLab.net internal domain. My Active Directory Domain Controller server (ADCT) also runs DNS, DHCP, and Certificate Services which I'm familiar with but don't understand completely. RRAS is already set up with NAT to provide the private internal network with Internet access. What I would like to do is be able to RDP into the servers/computers on the VMLab.net domain from my computer. Do I need to add the Remote Desktop Services role and enable the Remote Desktop Gateway service on RRAS in order to do this or is there a way to set up port forwarding on RRAS to just allow a direct connection to the internal servers...or both? What would the best practices be here? Network Diagram http://i.stack.imgur.com/4qfnk.png

• Resize Win2003 system+boot partitions to bigger disks & different controller?

  - by ane

  Have an old Win2003 server with 1 SCSI hard drive partitioned as follows: D: boot (includes D:\ntldr, boot.ini, etc.) C: system (includes C:\WINDOWS) Want to move the whole system to new hardware with bigger drives and different controllers. Specifically, C: to a 300GB SAS drive, and D: to a 2TB SATA drive. Tried: VMWare Converter - VMWare Server - Diskpart Result: Diskpart refuses to resize system or boot disks VMWare Converter - VMWare Server - GParted Result: Will not boot (see http://serverfault.com/questions/219868/resize-ntfs-system-partitions-with-gparted ) Attach original VMWare disk to a duplicate VMWare install - Diskpart Result: Will not boot (goes to Directory Services Restore mode) Backup Exec System Recovery Server Edition 2010 with Restore Anywhere (tried restoring both to VMWare and to the bare system, without VMWare) Result: Windows Boot error: Could not read from the selected boot disk. Check boot path. Supposedly this is a boot.ini problem, so I try bootcfg /rebuild from the recovery console. Says it can't find windows partition so it can't rebuild. Thought about Ghost but it's completely different hardware/controllers that we're restoring to, so I doubt it would boot. Reinstalling Windows from scratch is not an option due to critical custom software heavily embedded on the original machine. Has anyone been in a similar situation (with unusual boot/system partitions) before and figured out how to resize onto different disks?

• Why does Windows make random "device connect" and "device disconnect" sounds?

  - by Steve Elmer

  Hello, I've been noticing this since Windows Vista. I see it on Windows 7, now, as well. In any case throughout the day I notice that my computer makes apparently random device-connect and/or device-disconnect ("boink") sounds. I suppose it is the same sound you hear when connecting or disconnecting a USB device such as a thumb drive. I've noticed that this happens on each of three computers I work with at home, my wife's computer, and my machine at work. It happens without any user action at all - i.e. I'll be just sitting there (hands off my mouse and keyboard), and the computer will make the sound. There is no visual queue or anything. Just the sound. I have sometimes gone in pursuit of the sound - running virus scans, examining event logs and such, and observing task manager - but have never had any luck tracking this thing down, but have not had any luck. Surely someone else out there must be experiencing this, too. Any ideas? Thanks, Steve

• Can any postfix guru assist me determine how emails are still being sent via my server from unauthorized sources?

  - by Dave

  Hi all, I'm getting a little concerned as I run a small server hosting a number of websites and manage the email for a few dozen people. Just recently though I've had a couple of notifications from spamcop alerting me that spam has been sent from my server, and when I have a look over the logs from time to time I can indeed see that there are many repeated attempts of mail being sent from my server. Most of the time it gets knocked back from the destination servers but sometimes its getting through. Unfortunately I'm not linux or postfix expert, I can get by but had though I had my machine locked down quite securely, I don't allow relaying, when I check the online DNS/MX tools they tend to report my server as being OK so I'm not sure where to take it now and hoping someone might be able to throw me a few pointers. I get lots of entries like this in my MAIL.INFO log Jan 2 08:39:34 Debian-50-lenny-64-LAMP postfix/qmgr[15993]: 66B88257C12F: from=<>, size=3116, nrcpt=1 (queue active) Jan 2 08:39:34 Debian-50-lenny-64-LAMP postfix/qmgr[15993]: 614C2257C1BC: from=<[email protected]>, size=2490, nrcpt=3 (queue active) and Jan 7 16:09:37 Debian-50-lenny-64-LAMP postfix/error[6471]: 0A316257C204: to=<[email protected]>, relay=none, delay=384387, delays=384384/3/0/0.01, dsn=4.0.0, status=deferred (delivery temporarily suspended: host mx.fakemx.net[46.4.35.23] refused to talk to me: 421 mx.fakemx.net Service Unavailable) Jan 7 16:09:37 Debian-50-lenny-64-LAMP postfix/error[6470]: 5848C257C20D: to=<[email protected]>, relay=none, delay=384373, delays=384370/3/0/0.01, dsn=4.0.0, status=deferred (delivery temporarily suspended: host mx.fakemx.net[46.4.35.23] refused to talk to me: 421 mx.fakemx.net Service Unavailable) then there tends to be connection timeouts, so from what I see even though I had relaying disabled.. something is getting by and trying to send.. So if you can help that will be greatly appreciated, and any further logging/config info I can supply. Thanks

• Firefox proxy authentication with Kerberos: one service ticket per connection (Linux)

  - by Dari

  I am trying to enable proxy authentication via Kerberos for Firefox. The setup is: Active Directory domain (for LDAP and Kerberos; this works and I can log in the computer and get Kerberos tickets without problems) Microsoft Windows witness machine (on which Firefox runs fine with no ticket problem) CentOS 6.3 system with Firefox (the tests were performed with both the 10.0.1 ESR found in the CentOS package repositories and the 15.0.1 downloaded from Mozilla's website) BlueCoat proxy with Kerberos authentication enabled For the moment, Firefox requests an element of a website, gets an HTTP error code of "407 Proxy Authentication Required" from the proxy, gets a ticket granting service (TGS) from the domain for the proxy and performs the request again while passing the ticket. The transaction runs fine. However, when more elements are requested (in parallel), Firefox requests one more ticket per proxy connection. And this takes many DNS queries, Kerberos interactions with domain controllers and costs a lot of time (for example, the home page of Adobe takes several minutes to load and at the end, I have about 30 valid Kerberos tickets). I am stuck on this since a while, and help would be greatly appreciated. Minor information: the CentOS operating system is virtualized with VMware Player 3.1.3, but I do not think this would be a game changer.

• Sony PMB causing failure to load Windows 7 Pro 64-bit normally or even Safe Mode

  After installing Sony's Picture Motion Browser on my desktop with Windows 7 Pro x64, it always goes to Startup Repair due to Windows 7 failing to start. This always happens after I try to install it. I've installed with all unnecessary programs closed and all disk drives and unnecessary usb ports empty. I don't exactly know what is causing the problem. Any ideas? My desktop is an HP m8530f. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01469325&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&product=3740333&lang=en Only upgrades are an HD4350 and a 500W PSU. EDIT: Windows 7 cannot start now. I'm currently running diagnostic tests from the BIOS. EDIT: Here are the problem details. Problem Signature: Problem Event Name: StartupRepairOffline Problem Signature 01: 6.1.7600.16385 Problem Signature 02: 6.1.7600.16385 Problem Signature 03: unknown Problem Signature 04: 21201022 Problem Signature 05: AutoFailover Problem Signature 06: 8 Problem Signature 07: CorruptFile OS Version: 6.1.7600.2.0.0.256.1 Local ID: 1033 CONCLUSION: So, I think Sony PMB may have caused some sort of corruption in the system files. So if you have Windows 7 and plan on installing Sony PMB, find a Vista or XP machine to install on.

• Malware Defense Shows Up in PlayOn Settings/Logs Although System Has Been Thoroughly Cleaned

  - by nicorellius

  I was hit really hard by some nasty malware: Malware Defense. I was doing something I should not have been doing when I got it (surfing Pirate Bay for TV shows). It locked up my system and I had to reboot in safe mode. I was able to shut down the process and remove it using a malware killer tool. I then installed, after my machine was cleaned up a bit, Clamwin, Malwarebytes, and another AV tool. I cleaned the heck out of my system. Simultaneously, while this was going on, I was having trouble with my media-server, PlayOn. This tool is great, but has some bugs. One in particular is that it will not function well with AV software running. I found a way to allow the new AV software to run while using PlayOn, but it still says I have Malware Defense on. Firstly, Malware Defense is long gone. I cleaned all remnants from my registry and scoured my system with the above tools multiple times. PlayOn is getting some information that I have this crap installed on my system, but it's not. The system runs OK, but not optimally. I have a feeling it is causing my streaming to be interrupted sometimes. How is it that I can't even find Malware Defense on my system if I tried but yet somehow PlayOn is getting a finger print of it somewhere? I have gone back and forth with MediaMall to no avail. I kind of just gave up, because the streaming works OK. BTW, I also uninstalled/reinstalled PlayOn several times, reverted back to previous versions, etc. The only thing I haven't done is reformat my disk and reinstall Windows. I really don't want to do this if there is another way to remove this little print. Any ideas?

• How can you connect to a SQL Server not on your domain?

  - by scotty2012

  I have a test machine that's not allowed on our domain because we are testing corporately unsupported applications (SQL 2008 and Server 2008). I want to use management studio to connect to the SQL2008 server but can't get it working. I have authentication set to mixed-mode, I've checked 'allow remote connections to this server', but when I try to access it, I get the error A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53) Since it says the provider is Named Pipes, I enabled Named Pipes on the server, but still no dice. I've tried connecting to the system name, the IP, the system name\instance and IP\instance, all to no avail. Is what I'm trying to do not possible? Edit: Well, through some basic troubleshooting, I've found that I can't ping the server from my client computer, but I can ping the client computer from the server? They are both plugged into the same switch, and are sitting next to each other. The windows firewall on the server is turned on, is there some specific settings I need to enable? DAH! So it was the firewall blocking me. How can I enable the firewall and still connect?

• Troubleshooting: Monitor never turns on, system fans running, DVD-ROM does not open.

  - by Wesley

  Hi all, Here are my specs beforehand: ECS P4VXASD2+ (V5.0) motherboard FSB 533MHz Intel Pentium 4 2.40A GHz Prescott Socket 478 2x 256MB PC2100 DDR RAM, 2x 256MB PC133 SDRAM CoolMax 350W PSU DVD-ROM - will edit with brand & model 128MB ATi Radeon 9800 Pro AGP No hard drive So, I just put those parts together today and I tried to power it up, with the monitor connected to the Radeon 9800 in the AGP slot (mobo does not have VGA port). After turning it on, the CPU fan, graphics fan and system fan go on. However, the monitor remains in standby mode, despite being plugged in. Also, after pushing the button on the DVD-ROM drive, it does not open. I've used the DVD-ROM drive before with absolutely no issues. The graphics card was slightly buggy when I put it on another machine, which was left outside in winter weather for 3 months. (Still that computer's integrated graphics worked fine.) CMOS battery was replaced and jumpers are all set correctly. Now, I'm wondering whether the motherboard, CPU, PSU or GPU is the problem. What can I do to test which part is the problem? Just to clarify, I don't have a hard drive, so I usually boot Ubuntu from the disc drive. Anyways, thanks in advance!

• No clue for high load average on top

  - by Oz.

  We have several machines on Amazon (ec2) of the type c1.xlarge with 16 cpus, running the Amazon AMI. Details on the machine: 7 GB of memory 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each) 1690 GB of instance storage 64-bit platform I/O Performance: High API name: c1.xlarge One out of the several machines is showing a high load average, since we have run the last yum upgrade a couple of weeks a go. We did not yet update the other machines, and everything looks normal on them. The strange thing is that the top command not showing any hint for the cause of the load.

• VirtualBox VM running web server not accessible via external IP

  - by mwigdahl

  I have a Windows 7 machine running VirtualBox with an Ubuntu guest. The guest has a Bitnami LAMP stack installed. I have the guest configured for Bridged networking, and I can access the guest web server just fine from other machines on my LAN using the guest's IP. I'm trying to configure port forwarding so that I can access the web server from outside my LAN. (The router is a 2WIRE model as I'm on ATT's UVerse). I've set up port forwarding for ports 80 and 443 to the guest's IP in a similar manner to how I had them set up for my previous, physical web server, which worked just fine. However, I cannot seem to access the new, virtual web server using my external IP on the forwarded port. I suspected Windows Firewall issues on the host, but disabling it didn't solve the issue. Anyone have advice on what I should try next? EDIT: I've now attempted disabling the firewall on the guest with sudo ufw disable -- that doesn't seem to help either. However, after checking the router's port forwarding in more detail I may see the problem. My VM is named "linux" and in the router's configuration pages it shows up inconsistently. Sometimes it reports with a valid LAN IP and other times it doesn't show up with any IP. Even when it shows the correct IP the router indicates that it is disconnected. Could this be an indication that the 2WIRE router doesn't play well with VirtualBox's bridged networking mode?

• WinHttpCertCfg not importing certificate

  - by Ramon Zarazua

  I need to setup a deployment script that imports an SSL certificate that my service uses. I have tried importing with WinHttpCertCfg and with CertMgr to no avail. Here are the command-line arguments I have tried to use with both: winhttpcertcfg.exe -i <certname>.pfx -c LOCAL_MACHINE\My -p <password> -a <user service runs as> and CertMgr.exe -add -all -s -r localMachine -c <cert name> My It seems from what I have investigated that CertMgr does not allow you to import certificates with a password, so I'd rather get winhttpcertcfg working. When I run them I get the following output: WinHttpCertCfg: Microsoft (R) WinHTTP Certificate Configuration Tool Copyright (C) Microsoft Corporation 2001. CertMgr: CertMgr Succeeded However, when I look into the local machine certificates in MMC, try to load them from my service, or list it out through winhttpcertcfg, or even looking at the registry in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\MY\Certificates it is not found. I have tried all of the following: If I install the cert manually (Through CertMgr.msc dialogs) it works. The user installing is running as administrator The user installing has full access on the certificate The tools print out an error when something is wrong (wrong password) Tried it in multiple machines (All of them server 2008 R2) At this point I am officially out of ideas. Thank you.

• Maintaining "Portability" Between Linux and Windows 7

  - by lokheart

  I am using the following ways in my office's Windows 7 machine to maintain my "portabilibity" when disaster strikes and I need to switch computer while I have no luxury of time for reinstalling all my program to the new PC. a majority of programs I used are portable, mostly from portableapp.com, like notepad+, GIMP, even R, I extract them and store them in a folder in My document, in a structure similar to the default portableapp installation when they are installed to a thumbdrive only a few software that portable version is not available and I will install them as usual all of my working files are stored in a folder in My document I regularly backup them all using syncback, because this program can keep versioning of my backup, and the backup is stored in a portable drive. One day I need to switch my computer and the operation is relative simple for me: I just move the two folders mentioned above into the my document folder of the new PC, install those few "non-portable" program in it, and this is almost done, some minor hiccups can be solved by reinstalling the portableapp into the drive. Overall speaking it is a smooth process. I would like to maintain the same degree of "portability" in my home Linux desktop (Ubuntu or Mint, I'm still deciding), that is, if my Linux crash and I need to reinstall it again. All I need to do is the move the two folder back to the new Linux, and most of my work will be almost ready to be worked on again. But I don't know how to find a Linux-alternative of portableapps. Being a newer to Linux, can anyone tell me whether this is possible in Linux?

• Modifier key bug with Adobe Design Standard CS4 (Mac OS 10.6.6)

  - by Andy

  When I launch the Adobe apps, they ask me if I want to delete the preferences file. I say 'no'. Then, when using the apps, none of the tools seem to work properly, eg in Illustrator, I can't move objects without it duplicating the object. Photoshop constantly displays the contextual menu icon that usually only appears when you hold down the control key. I can't do any work in them when this happens, so I am forced to log out and then back in. They work for a while and then this annoying bug happens again. I think it must be to do with the modifier keys (command option and control). I think Adobe's apps must think I'm permanently pressing the modifier keys down - the thing is, no other app on my machine has this problem! Does anyone else experience this? Or have a fix for it? Any suggestions much appreciated. Running: Mac OS X 10.6.6 on an iMac. Adobe CS4 Design standard installed.
