• Unusable network, packet losses between router and NIC

  - by KáGé

  I have this setup: Gigabyte P35-DS3P motherboard Asus NX1101 PCI network card (the one on the motherboard got fried a few years ago by a power surge) Asus RT-N16 router Windows 7 x64 I think the other specs are irrelevant here, but I'll post them if you say so. Until a week ago everything was fine, but then my network became unusable: websites start loading but timeout before anything would come through (true for the web interface of the router as well), I can't reach the computer from my notebook and Windows' ping utility measures a ~50% packet loss between the computer and the router. Pinging localhost is good. The router works completely fine when wired to my notebook. I also tested different ports on the router, different cables, different router and connecting directly to the modem, but it's still the same. Sometimes it works for a few minutes right after turning on the machine, but then it becomes crap again, but mostly it's useless from the start. I've tried updating the firmware on the router, updating the driver for the network card (after which I started getting BSoDs in every 15 minutes), reinstalling Windows, swapping to Fedora 15 but none of them changed anything. Does this mean that the network card is dying, or could it be something else? If it's the card, what model do you recommend as a replacement? (Could be PCI or PCI-Ex x1) Thanks for your help.

• All FireFTP passwords gone after auto-update

  - by GitaarLAB

  For the last six months (since the Firefox madness started and they keep on taking control of my PC) I'm terrified to touch Firefox. Problem is however, I've been using it in my business (since once upon a time it was a trustworthy application with useful extensions like FireFTP) and that installation (and plugins) holds four years of information. So Firefox continually deletes my important data (by) messing up (or blocking/or worse: auto-updating) my plug-ins, even crashing my computer as a result. Today Firefox killed FireFTP by (again) autoupdating FireFTP without my permission, and I did my best to disable that nonsense in about:config). Result: none of the (over 100) FireFTP accounts can be logged on to, they suddenly all ask for a password. I do not have the time to to find all of the passwords and reconfigure FireFTP again. How can I undo the mess Firefox created once again? That is, where are the passwords, how do I downgrade? As a side-question, how can I make Firefox behave again? I'm the boss of my computer, not them! How can I once and for-all take back control and completely kill every kind of auto-update feature?

• Printer spooler service stop running when sent print job

  - by Hanan N.

  Every time i am sending a print job to the printer, i am don't get any response from the printer, and at the printer job list at the status of the job, i see that there was an Error, but it don't give me any clue on what could be the problem. After some investigation i found that every time that i send the print job to the printer the printer spooler service stops to run, then after a second or two it start again (i think that this behavior is related to the printer spooler settings to rerun it self after it stops). Things that i have tried so far: Remove and Install again the Driver. After removing the driver, i have removed the unnecessary registry keys according to this article from Microsoft, these are: Rename all files and folders in: c:\windows\system32\spool\drivers\w32x86 Remove anything but Drivers Print and Processors: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environment\Windows NT x86 Remove anything in here: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors but: BJ Language Monitor Local Port Microsoft Document Imaging Writer Monitor Microsoft Shared Fax Monitor Standard TCP/IP Port USB Monitor WSD Port Disconnect and Reconnect the Printer. Clean the computer from Viruses & Spywares. Currently i am stuck, i have no more things to try, if anybody know about any kind of solution please let me know about it. Since i am want to keep this post as general problem that relate to the printer spooler, and not just my particular problem, i didn't included inside the windows version & the printer model, they are (although i think that it isn't relate just for that particular model): Windows 7 32bit, HP Officejet 4500 G510g-m (connect to the computer via USB). Thanks.

• High fan speed with no reason

  - by Klaus

  For a few weeks, the fans of my Lenovo B590 laptop, running on Xubuntu 14, turn to high speed a few minutes after it is turned on. The fans won't speed down until I turn the computer off. This is quite strange, since This didn't happen before The temperatures are quite low (are they ?) $sensors Adapter: Virtual device temp1: +36.0°C (crit = +88.0°C) temp2: +30.0°C (crit = +126.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +37.0°C (high = +72.0°C, crit = +90.0°C) Core 0: +34.0°C (high = +72.0°C, crit = +90.0°C) Core 1: +31.0°C (high = +72.0°C, crit = +90.0°C) thinkpad-isa-0000 Adapter: ISA adapter fan1: 0 RPM pkg-temp-0-virtual-0 Adapter: Virtual device temp1: +37.0°C $sudo hddtemp /dev/sda /dev/sda: ST500LT012-9WS142: 33°C The computer is under low load: top - 08:30:15 up 16 min, 2 users, load average: 0.28, 0.23, 0.23 Tasks: 197 total, 1 running, 196 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.8 us, 0.5 sy, 0.0 ni, 98.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem: 3607944 total, 1973956 used, 1633988 free, 99660 buffers KiB Swap: 3744764 total, 0 used, 3744764 free. 789936 cached Mem The BIOS is up to date (and there are no fan settings in it) The fan is clean and dust-free Why would the BIOS turn the fans to high speed where there seem to be no reason for that ? It seems that we cannot control the fan manually with this model, so I guess the only solution is to understand why this happens.

• Dell XPS 1530 DVD-RW firmware problem

  - by josecortesp

  Hello everyone. I have this XPS laptop since a year and a half ago. About 2 months ago, with the waranty expired, i tried to run the optiarc slot load DVD-RW firmware update, and said everything was okay. Then I restarted it and the problem started: Now, every single time I turn on my computer, it get stuck at the BIOS POST until the drive sounds like "ready" and then the computer starts normally. And this happen EXACTLY the same when it's getting back from sleep. I'm pretty sure is not a software issue, because I tried with Vista Home Premiun 32 bits, Ubuntu (from 8.10+)32 & 64, and with W7 64. Already tried to run the firmware installer like a million time, in case it is a failing install with no luck. Also, google it to see if someone has the same problem, and again, no. The Drive performs pretty okay once the System is on, but waiting to the drive to be ready everytime is really annoying. The Firmware I updated was this, and the drive is: K937C Assembly, Dvd+/-rw, 8, SLOT, 1530 Sony Nec Optiarc Inc. I'll apreciate any help you can give me

• no administrator password for Windows 7

  - by huskergirl78

  I'm a secretary and my boss set up my new Windows 7 OptiPlex 7010 (Dell) computer for me while I was on vacation (he does not remember setting any "administrator" password). We are a small office so there is no system password set, either. I've used it for 6 months, all the while I couldn't access network drives, etc., without an administrator password. It was annoying, but I could still get my work done. Finally, on a slow day I took it upon myself to "fix" the problem, and in all my infinite wisdom, I managed to change my user account from administrator to standard user, so now I really can't do anything. I can't download or install any programs, move or rename files, etc. I tried the Dell suggested solution, but the BIOS tells me there is no password set, so it has to be a Windows 7 problem. All the solutions I have come across require an administrator password to let me do them. What can I do to find out the admin password so I can use my own darn computer!? Is there a default admin password?

• Why can't I mount an image hosted on a read-only HFS+ partition via Boot Camp?

  - by deceze

  I have come across the following phenomenon and would like to know how leaky Windows' file system abstraction is or if there's something else involved. I partitioned the hard disk of my MacBook Pro and installed Windows 7 (64 bit). The Boot Camp driver package includes file system drivers that enable Windows to access the Mac OS HFS+ partition. It's read-only access, but it works. Now, I have some disk images of stuff I usually install, so I grabbed a copy of Daemon Tools to mount them. When I mount an image saved on the HFS+ partition, about two out of three installers on these disks (usually InstallShield) crash with all sorts of weird errors. Most are just gibberish that lead to all sorts of non-solutions on Google, one was "This application is not the right type for your computer, check if you need 32 or 64 bit versions." When moving the image files to another Windows 7 computer on the network and mounting them from the network share, they work fine. My question now is, why do applications behave differently depending on whether the read-only image file, which should be abstracted away through the read-only virtual Daemon Tools drive, is located on a read-only HFS+ partition or on a Windows network share? And I'll just roll this into the question as well since I was wondering: Does the file system of a network share matter? Does the client system need to understand the file system of the share host or is that abstracted away in SMB?

• Equivalent of scp -l bandwidth_cap for .ssh/config?

  - by Mark Bennett

  Short form: You can limit the bandwidth the scp uses with the -l switch, you pass a number that's in kbits/sec. I'd rather set this in my .ssh/config file for certain names machines. What's the equivalent named setting for -l ? I haven't been able to find it. Followup question: Generally, not sure how to map back and forth between ssh command line options and config names, short of doing Google searches or manually comparing man pages on a case by case basis. Is there a table that directly equates the two? Longer form of first question, with context: I've started using ssh config quite a bit, especially now that I need to go through a proxy and do lots of port mappings. I even define the same machine more than once depending on what type of tunneling I need. However, when uploading a large file, it's difficult to do anything else on my machine. Even though I have more download bandwidth than up, I think that scp saturates the link so even my small requests can't reach the Internet. There's a fix for this, using the -l bandwidth command line switch for scp. scp -l 1000 bigfile.zip titan: I'd like to use this in my config instead, so I'd create an additional named entry called "titan-upload" and I'd use that as the target whenever I upload. So instead of: scp bigfile.zip titan: I'd say: scp bigfile.zip titan-upload Or even set different caps depending on where I am: scp bigfile.zip titan-upload-from-home vs. scp bigfile.zip titan-upload-from-work I'm generally on Mac and Linux.

• Strange WiFi problem - network is "not connected" but works

  - by GalacticCowboy

  Background I'm using a Windows XP tablet PC connected to my home network. I do broadcast the SSID, but otherwise the wireless network is locked down as tight as I can make it - WPA2 with a strong key, MAC filtering, etc. I've had this computer for about 4 years and the router for about 6 months. Before that, the previous router was set up in the same way, and I've never had any particular problems. Problem This morning - as I type this, as a matter of fact - Windows is reporting that none of my network connections are connected. Yet somehow my Internet connectivity still works! ipconfig reports a valid IP address, domain, etc., even though Windows apparently doesn't know about it. I tried repairing the connection and it had no effect - the repair eventually timed out. I'm pretty sure that I could reboot the computer and/or the router, etc. and it would fix the problem. However, I'm more interested in knowing if any of you have ever seen anything like this, and what might have caused it? Since it works I'm not inclined to mess with it too much. My concern is that it's a precursor to bigger problems.

• Can't start Windows 7 after cloning HDD

  - by Paul

  Brief description: cloned HDD1 - HDD2 HDD1 partition 1 boots HDD1 partition 2 boots HDD2 partition 1 boots HDD2 partition 2 doesn't boot Windows, but is bootable in general Now verbosely: In all the cases computer is the same. I have two Windows 7 installations on HDD1 - both are booting fine. I choose between them using standard Windows 7 boot loader menu. Technically there are 4 partitions: 100 MB Boot loader partition (active), Windows 7 copy 1 (25 GB), Windows 7 copy 2 (150 GB) and Working partition. All are primary. In past few days I tried to clone the whole HDD1 to HDD2 of the same size (but 2,5 inch form factor) as is using Minitool Partition wizard. Everything has been copied, all files are accessible, no faults in file system structure, even boot loader wasn't damaged and I hadn't to repair it. But I can boot only first installation of Windows 7 (it boots without issues). When I choose the second installation, I get immediately a completely black screen without any texts, cursors and other data. HDD isn't accessed after that. This black screen is sensitive to Ctrl-Alt-Delete which causes computer reboot. I did some experimenting: Installed Windows 7 to that partition - it booted fine. Then I renamed "Windows" to "Windows.old" and copied Windows directory from HDD1 as it was, using Far Manager, and got the same troubles - black screen. (Of course I performed renaming and copying from other copy of Windows). So, it seems that problems are inside this installation of Windows, somewhere in its files.

• Files deleted. What could have happened?

  - by jjfine

  I'm having a weird issue today. I was writing and testing out some simple cgi scripts this morning when I realized that I couldn't run them from one of the other computers on the (windows) network. So I had my network admin come in and take a look at what was going on. A few minutes later a co-worker came in and told me that a bunch of files he was working with as well as a bunch of others (all *.c files) on the network drive got deleted. He also noticed some strange apache_dump_500.log.txt files in the same directories where the files got deleted. The apache_dump_500.log.txt files all look like this: REDIRECT_HTTP_ACCEPT=*/*, image/gif, image/x-xbitmap, image/jpeg REDIRECT_HTTP_USER_AGENT=Mozilla/1.1b2 (X11; I; HP-UX A.09.05 9000/712) REDIRECT_PATH=.:/bin:/usr/local/bin:/etc REDIRECT_QUERY_STRING= REDIRECT_REMOTE_ADDR=<my computer's local ip> REDIRECT_REMOTE_HOST= REDIRECT_SERVER_NAME=<my computer's domain url> REDIRECT_SERVER_PORT= REDIRECT_SERVER_SOFTWARE= REDIRECT_URL=/cgi-bin/trojan.py I looked and I don't have any trojan.py in my cgi-bin folder. And all my apache logs are clean. Windows event logger seems to not have any traces of what happened either. My httpd.conf: http://pastebin.com/Yny2Yh8v I think we've got some kind of virus that added this trojan.py file to my cgi-bin, ran the script, and deleted the script and any traces from the logs. Is this a thing that happens? Any ideas whatsoever would be much appreciated!

• Why do I need to set up Autologon values in registry twice before it works and can i fix this?

  - by jJack

  Background: As part an automated testing suite I am building, I need to set up Autologon on my virtual machines 'on demand'. By on demand, I mean that I don't want to necessarily pre-configure my VM or any snapshot to have Autologon set up already, for security reasons and also a huge business case. My solution so far: I'm copying a script to the guest machine and then using Sysinternals PsExec to execute it. The script is: reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v DefaultUserName /t REG_SZ /d myusername reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v DefaultPassword /t REG_SZ /d myfakepassword reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v DefaultDomainName /t REG_SZ /d mydomain reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v ForceAutoLogon /t REG_SZ /d 1 reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /f /v AutoAdminLogon /t REG_SZ /d 1 reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\AutoLogonChecked" /f /ve /d 1 Note: I don't believe AutoLogonChecked is required for machines post Windows 2000 but I'm doing it just in case for now. Maybe ForceAutoLogon isn't either, not sure yet. The Problem: I see PsExec executes this properly and all the values are in the registry, however when I restart the machine, the user isn't automatically logged on...When I run this a second time then restart the machine, the user is finally logged on. A diff between the registry states shows that the first time I run this, it is missing both the "1" for AutoAdminLogon, and also the DefaultPassword key. The second time I execute it, these values are correctly intact as I intended. So, what is going on here? Is this expected? This post claims in the end that it really all just works (the problem was that a logoff script was setting off the values). Doesn't seem to work for me however.

• Looking for a real DisplayPort hub/splitter

  - by squircle

  In my search for a new display, I came across the Dell Multi-Monitor Hub MMH11, which seemed to be an alternative to my search for daisy-chainable DisplayPort displays. However, before I cave and spend $179 on this device, I am wondering if this will be similar to other splitting devices where it appears to the computer as one big monitor and the device does the splitting (which I don't want). Or, does this use the packet-based nature of DisplayPort to present two/three separate displays to the computer? Also, would this device work on my MacBook Pro? (I know the Dell site says it's for Windows, but it also says that no driver installation is required. I'd assume since the MBP supports DP 1.2 it would work, but it's better to ask). Thanks! Edit: I've checked out the similar-looking Cirago DisplayPort splitter, but I have extreme doubts as to whether or not it's a genuine displayport splitter, or just another monitor-conglomerate. Their DVI solution looks identical to Dell's, which I'm pretty sure won't do what I want. I also don't want to order this DisplayPort "hub" and find that it doesn't do what I want it to.

• Windows 7 hangs on black screen for a while after log in

  - by steini

  I get the welcome screen. I click on my user and get the "logging on" screen. After that all I get is a black screen with a mouse cursor. I can't even start task manager. No ctrl+alt+del or ctrl+shift+escape. It stays like this for about 10 minutes, then the desktop finally starts loading. According to the hdd led on my case, windows isn't even trying to access the hard drive for that whole time. It's just hanging doing nothing it seems. What I have tried: Uninstalled video driver and removed leftovers with driver sweeper Disabled all startup programs and non microsoft services Loaded "last known good configuration" Ran the alleged "black screen fix" from prevx against my best judgement (don't really like running random exes without knowing what they do at all) None of that works. I can boot into safe mode normally. My specs: i7 920 Gigabyte X58-UD3R Gigabyte HD5870 1GB 12GB Mushkin Silverline 1333MHz Windows 7 Ultimate x64 I'm also having another problem which I suspect is related. After I have gotten the computer up and running, everything works perfectly, but when it's been on for a while it starts behaving strangely when changing display modes. When I start up a game or anything that changes the screen resolution the computer freezes for about a minute every time until I reboot again. I think this is probably related to the black screen problem. Just thought I'd check to see if anyone has had the same problem. Let me know if I should post any more details about my system to help diagnose this. Thanks in advance.

• Hadoop streaming job on EC2 stays in "pending" state

  - by liamf

  Trying to experiment with Hadoop and Streaming using cloudera distribution CDH3 on Ubuntu. Have valid data in hdfs:// ready for processing. Wrote little streaming mapper in python. When I launch a mapper only job using: hadoop jar /usr/lib/hadoop/contrib/streaming/hadoop-streaming*.jar -file /usr/src/mystuff/mapper.py -mapper /usr/src/mystuff/mapper.py -input /incoming/STBFlow/* -output testOP hadoop duly decides it will use 66 mappers on the cluster to process the data. The testOP directory is created on HDFS. A job_conf.xml file is created. But the job tracker UI at port 50030 never shows the job moving out of "pending" state and nothing else happens. CPU usage stays at zero. (the job is created though) If I give it a single file (instead of the entire directory) as input, same result (except Hadoop decides it needs 2 mappers instead of 66). I also tried using the "dumbo" Python utility and launching jobs using that: same result: permanently pending. So I am missing something basic: could someone help me out with what I should look for? The cluster is on Amazon EC2. Firewall issues maybe: ports are enabled explicitly, case by case, in the cluster security group.

• Troubleshooting an overheating CPU

  - by Jeff Fry

  I & my father just recently put together a new PC. Specs below. From the very beginning, on boot it will often complain that the CPU is too hot. If I sit in BIOS and watch the CPU, it'll drop back down from red to blue (<72C), at which point I've tended to just boot into Windows...and haven't had any problems. In fact, I've played a couple hours straight of Skyrim at max settings, and not had any visible issues. That said, I've occasionally walked away & come back to find that it's crashed. Yesterday, it crashed (while idle) twice in 12 hours, which shifted the balance from busy-with-life to nervous-I'm-about-to-melt-something. I just installed Core Temp which is showing my 4 cores fluxuating between 70-98C. I'm guessing at this point that the CPU fan may be incorrectly installed or defective. My first thought is to either (a) add water cooling (which the case supports) and / or (b) replace the CPU fan with an after-market one. That said, I'm very open to suggestions. A note, while I certainly don't want to burn money here, I have a baby coming any day now and am still unpacking from a recent move so if I have a choice between an option that costs money and another that takes a while...I'll happily spend a bit extra. Side question: Should I be nervous to even have this on at this point? Let me know if there's something useful I could add to my report. Otherwise, I'm looking forward to your suggestions! Thanks.

• Task scheduled to wake laptop - only works when lid is open

  - by JD Pack

  I am running Windows 7 Starter on an Acer Aspire One laptop. I want my laptop to automatically run a task (backup the HDD to a network drive) once a week in the middle of the night. I scheduled the task in "Task Scheduler" and checked the box to wake the computer to run the task. I also changed the advanced power settings to allow wake timers. This was half of the solution. It now works flawlessly when the lid is open... the computer can wake itself up from either sleep or hibernate mode to perform the backup. When the lid is closed however, its sleeping beauty. Any ideas? I don't want to have to remember to open the lid once a week. It sort of defeats the purpose of an "automatic" backup. Update: I discovered that it can wake from sleep (or hybrid sleep), but not from hibernate when the lid is closed. This is good news. I'd still be curious about how to get it to work from hibernate, but I'm pretty happy about waking from sleep at least.

• How do you enable view source in ie8 when it gets magically diabled

  - by Tim Meers

  I have multiple computers that all seem to have View Source disabled from the content menu when you right click on a web page. Now I know it's not that the web page is some how disabling it, I'm pretty sure thats not even possible. But alas I have at least 3 machines in my office (not on AD) that have this problem. I have also worked on clients computers that have this same issue. It's down right maddening! I tried to Google for it, but it just shows results from the dawn of IE6 in all of it's "glory" with a bug where if the cache was full it would be disabled. But this is not the case in IE8. Any body have a clue why this is happening, or a fix for it? Maybe a reg setting? Update: So I got a little closer to solving it, but there was still an issue on one computer where it allowed it not is HTTP, but not in HTTPS. One other computer works correctly in both. I Found these two keys missing in the registry: [-HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\View Source Editor] [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\View Source Editor]

• Application Virtualization

  - by Peter Versnee

  I have been looking for a solution to virtualize my desktop application as a SaaS. After picking Citrix XenApp as the best solution for my case and trying for ever to get it to work (with some more experienced people) I can't help but to conclude that Citrix has too much problems for my case. Every time I fix one thing some other thing pops up. As I can't imagine Citrix XenApp is the only way to deliver my application to my clients, I'd like to ask you experienced guys if you think there is an other way to deliver it whilst meeting my requirements. I've got no money issues - time on the other hand... My requirements: My application must run on a windows server; The application should be virtualized with the application window only (no desktop); Content Redirection (my application is the only one virtualized, so PDF, DOC(X) etc. is on the users' system); Easy user management; SSO;* Cross platform (Windows, Linux, Mac OSX).* I truly hope I don't annoy you with another of the same question. I've tried to find the same question here and - obviously - didn't found it. *) these I can live without, however very much appreciated

• Windows media scaling/interpolation method

  - by MichaelH

  Usually in Windows, if videos or other media is upscaled from a certain resolution to a higher resolution (e.g. "monitor size"), a bilinear filtering algorithm or similar is used, such that the upscaled material doesn't look blocky. On my system however, the used interpolation algorithm changed from 'bilinear' to 'nearest neighbor' at some point, with the effect that upscaled videos (e.g. viewed in MPC or WMP, and also Skype video streams) and games (e.g. from PopCap) appear rather blocky. Not sure what the common factor between those is, could be DirectShow(?). I am not aware of having changed any setting that could have affected this state, in fact I am not even aware such a setting exists. I'm guesing that some installed software must have changed something on my computer. My computer is running Windows 7, but I had already experienced the same effect on an XP machine some while ago, where it changed back again to the more pleasing bilinear interpolation after a while, as magically as the first time. What could be wrong with this installation, and how can I change this upscaling interpolation behavior?

• Unable to connect to server after a certain amount of time

  - by Troy

  I am a business FIOS subscriber with 5 static IPs. I have the following network setup: Verizon provided ONT Dlink switch Dell server running Ubuntu 12.04 with iptables enabled and a static IP address. The makes/models of hardware are: FIOS ONT Alcatel-Lucent I-211M-H ONT D-Link D-Link Web Smart Switch DES-1228P Server Dell Optiplex 755 (Ubuntu 12.04 Server) I have iptables running on the server with http, https and ssh ports open. I can connect to a website on the server from an external computer, but after a certain amount of time (mins to hours), I can no longer connect. All I have to do to re-enable connectivity is connect to the server via SSH from a computer INSIDE the network. I don't have to actually login, I just have to establish a connection. I can then access the website externally again. I did some googling and it seems some of verizon's equipment had an ARP bug where the ARP entries would expire after a certain time period, but those issues all seem to be from back in 2009 - 2010. I know the switch has an 'auto learning Mac address' feature, but I'm not sure if that could be the problem or not. Does anyone have any ideas or advice on how I can troubleshoot this? Thanks!

• Anonymous Login attemps from IPs all over Asia, how do I stop them from being able to do this?

  - by Ryan

  We had a successful hack attempt from Russia and one of our servers was used as a staging ground for further attacks, actually somehow they managed to get access to a Windows account called 'services'. I took that server offline as it was our SMTP server and no longer need it (3rd party system in place now). Now some of our other servers are having these ANONYMOUS LOGIN attempts in the Event Viewer that have IP addresses coming from China, Romania, Italy (I guess there's some Europe in there too)... I don't know what these people want but they just keep hitting the server. How can I prevent this? I don't want our servers compromised again, last time our host took our entire hardware node off of the network because it was attacking other systems, causing our services to go down which is really bad. How can I prevent these strange IP addresses from trying to access my servers? They are Windows Server 2003 R2 Enterprise 'containers' (virtual machines) running on a Parallels Virtuozzo HW node, if that makes a difference. I can configure each machine individually as if it were it's own server of course... UPDATE: New login attempts still happening, now these ones are tracing back to Ukraine... WTF.. here is the Event: Successful Network Logon: User Name: Domain: Logon ID: (0x0,0xB4FEB30C) Logon Type: 3 Logon Process: NtLmSsp Authentication Package: NTLM Workstation Name: REANIMAT-328817 Logon GUID: - Caller User Name: - Caller Domain: - Caller Logon ID: - Caller Process ID: - Transited Services: - Source Network Address: 94.179.189.117 Source Port: 0 For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

• "Ethernet" doesn't have a valid IP configuration

  - by Xuzuno

  I'm using an ethernet cord to connect to my internet and it has been working well until Thursday morning when I turned on my laptop (Windows 8) to see a yellow triangle sign in the bottom right hand corner, in front of the ethernet connected symbol. Since then I haven't been able been able to access the internet from my computer. When I hover over it, it says that it is an "Unidentified network" and there is "No internet access". I've run the Windows 8 troubleshooting and it says that the problem found was ""Ethernet" doesn't have a valid IP configuration", but I'm unsure how to fix it. I'm thinking that the problem is to do with my computer rather than my network, because I've tried another laptop (Windows 7) through the same ethernet cable and connection and the internet works fine on the other laptop. I've tried so many fixes that I've found online, with none of them actually working. Yesterday I even tried a full system reset, where I re-installed Windows 8, re-partitioned and wiped everything off the hard drive, but it still appears have the exact same problem. Today I also purchased and tried a new ethernet cable which didn't work, so I then purchased a USB to Ethernet adapter, to make sure that it wasn't my ethernet port on my laptop that was faulty. That didn't work either, and the same problem still remains. I feel like I've tried everything, so can someone please help me?

• Mac dev folder missing, SSH not working

  - by SamGoody

  A few days ago, SSH stopped working. When I try logging in a get the following message: PTY allocation request failed on channel 0 stdin: is not a tty fatal: unrecognized command '' Connection to 74.52.61.194 closed. Web searches have shown me that there might be something wrong with /dev/std. But my computer lacks a /dev/ drive. There is an Alias to /dev/ [hidden, but I've revealed hidden files to do this search], but when I try to open it I am told that it cannot find the folder it is aliasing. Now, many a web search tells me that without a dev folder, the computer doesn't work, but it does seem to work, except the SSH. Also, are there any tools that can save my SSH preferences so that I don't have to, each time, type out the username@adrees, password, path all of which are long and complex? Not looking for a Filezilla type client, there are many of those. Looking for a command line like putty, that lets me use bash on the remote client. Am on Macbook Pro, latest version of Tiger.

• SQL Server Installation: Is it 32 or 64 bit?

  - by CapBBeard

  Hi, Recently I was performing an OS upgrade on one of our DB servers, moving from Server 2003 to Server 2008. The DBMS is SQL Server 2005. While reinstalling SQL on the new Windows installation, I went to another of our DB servers to verify a couple of settings. Now, I always thought this second server was Server 2003 x64 + SQL 2005 x64 (from what I'd been told), but I now have my doubts about this. I now suspect that it is in fact only 32 bit SQL, however I'd like to verify this. Here's some details: The OS is definitely 64 bit. xp_msver shows Platform as NT INTEL X86 SELECT @@VERSION shows Microsoft SQL Server 2005 - 9.00.4035.00 (Intel X86)... However sqlservr.exe is not shown with '* 32' in taskmgr, does anyone know why this is the case, if it is in fact 32 bit as claimed? Despite this, it does seem to be running out of the x86 program files folder. If I do the same checks on a confirmed 64 bit installation, it does give back the expected 64 bit readings, which can only prove that this server in question is only running in 32 bit. Now, that being the case, the question arises about how much memory this '32 bit' install can use. Task manager reports about 3.5GB memory usage for sqlservr.exe (The server has 16GB physical). I suspect that AWE has not been configured at all, and therefore the server will be significantly under-utilised (remembering that the OS is 64 bit) if SQL is simply using a 32bit address space. Is this assumption correct? I feel the server should have SQL reinstalled as 64 bit in order to fully utilise the hardware platform, however it is currently heavily in production; this will be no easy task. I suspect we may just have to configure AWE correctly and let it be for the time being (Unless this is a bad idea?). I apologise that this question is a little vague/lost; I'm no SQL expert, just trying to get a handle on what's going on here.
