• intermittent SSH with ssh_exchange_identification error

  - by rafamvc

  My ssh connection to my server works every 30 min for around 10 min. Things that I figure out that might be the problem: The server is underload (it is a database server), but on those spare moments that I can connect, it is still under the same load, which doesnt make sense. The server is a ubuntu, and the consolekit was using a lot of virtual memory. Restarted the consolekit and it seems to be using a right amount of memory now. It is not the host alows or deny. Those are setup properly. It is not a firewall problem. Those settings were working and the same settings are working for other similar machines. It is on the ec2. Amazon cloud.

• Missing Desktop Icon Labels in Windows 7

  - by Buzzedword

  Hey guys. Big problem that has been bothering me to no end. My desktop icons have been stripped of their icon labels, and nothing seems to be recovering them. To be clear, when I attempt to rename, the text shows up, and when I view my desktop in an explorer window, all text is preserved. System restore to a stock state will not recover. No changes have been done to the computer-- no installs or downloads for two weeks prior to this error. Rebuilt the icon cache, still no response. Anybody know what can be causing this problem? Screenie below. Thanks in advance. OS: Windows 7 Enterprise 64-bit Profile: Local, non-roaming Image: http://img688.imageshack.us/img688/5152/capturemr.png

• How do I prevent users from entering a blank value in an Excel sheet?

  - by Tola Odejayi

  I want to restrict users to entering either just 0 or 1 in an Excel 2007 sheet. I use the Data Data Validation dialog to do this, but I'm finding that it doesn't stop them from entering blanks. What I would like is for there to be a prompt when they enter blanks, just like the one that appears when they enter any other non-blank data that is not 0 or 1. I plan to fill the sheet with 0s before applying the validation, so there should not be a problem with erroneous data. Also, I'm open to using VBA to fix this problem.

• Windows 7 hangs after longer inactivity of user

  - by scooby37

  I have serveral PCs running Windows 7 in different falvors (32- / 64-bit / Professional / Ultimate / ATI / Nvidia) - they all have one problem in common... ...if I don't work on any of them for a longer time and the screen goes off as it should be (all default settings!) they sometimes go into some kind of sleep mode where I get to see the desktop or whatever I did before leaving after moving the mouse or pressing a key - but nothing reacts for a different amount of time from serveral seconds to serveral minutes! Any hint that helps solving this anoying problem would be very welcome ;-)

• Windows 7 boot error 0xc0000225 after falling down

  - by Hulehule20

  My Toshiba netbook fell down and hasn't booted again. When I start Windows 7 it immediately says: Windows failed to start... Status: 0xc0000225 Info: The boot selection failed because a required device is inaccessible. After that, there are a few things to consider: There's a Linux distro Linkat which is also installed in the computer. It starts normally without any problem and it doesn't seem to display any errors when it boots. I restored all computer OSs with clonezilla and some images provided by the manufacturer, and it's done nothing. I have already checked the basic components of the PC (RAM, Hard Disk, WLAN Card) are pluged in and working. My impression is that's all about some broken part inside, though the Linux OS starts normally. Does anyone know a way I can fix this or at least any software for identifying the problem at all?

• What are the different file permission codes and what do they mean?

  - by zeckdude

  I am working with a file upload script. I am currently uploading a file and then trying to echo out an anchor linking to that file, but since I used mkdir() with 0700 permissions to upload the file, it won't allow me access to view the file. I am pretty sure the problem I am experiencing is because of the file permission code I used. The problem is I just don't know what all the different file permission codes are and what they mean. Can somebody please list out all the different file permissions and what they each do?

• Windows Update and IE fail to connect, but Chrome fine?

  - by I Gottlieb

  Out of ideas on this one. (Running Windows Vista.) I have a program that accesses the internet to retrieve financial market data. One day it tells me that it can't log in -- timeout error. I check the documentation and it says must have a working copy of IE browser installed. I check IE (have IE9) and sure enough -- it just spins. No error message, not timeout, no 'try later' -- just spins -- as far as I can tell, indefinitely. Any page, any address. Even access to a localhost site just spins. Chrome works fine. So does another program I have that fetches market data. Windows 'diagnose and repair' says my internet connection is working fine. I tried uninstall/re-install of IE. Same spinning. I tried to install Windows Updates, and guess what? I can't. I comes up with error 80072efd; checked documentation for the error and it says I should check firewall blockage. Thing is, the only firewall I have is Windows Firewall, and obviously it wouldn't be blocking Windows Update. In contrast, Windows 'Help' in all programs has no problem accessing the Internet. I had a filter on the internet connection, and this was updated just prior to first appearance of the problem. But I uninstalled the filter entirely (official, with passwd from the company's service rep) -- and no difference. I'm guessing that a high level Windows network service file is corrupted -- used only by MS programs and their ilk, but how do I find it? I'd like to avoid having to do a clean install of Windows. Much obliged for any insight. IG Ramhound -- Thanks for reply. I'm familiar with virtual machines as in e.g. JVM or an emulator for an alternative architecture or (theoretical) Turing Machine equivalence. But I'm not familiar with the way you're using the term. Please clarify -- what one needs for this VM 'test' and why you expect it will provide an advantage of insight into the problem. And what sort of 'configuration issue' are you referring to? IG

• Excel: #NAME? appearing when linking/referencing other spreadsheets/workbook cells

  - by Mike

  I'm updating a spreadsheet that refers to data in another worksheet =NameofWorksheet for some reason I get #NAME? in some of the cells, even when the actual path is correct. The only way to overcome the problem is to open up the source spreadsheet and then recalculate the destination spreadsheet. But, if I then close the workbooks; open up just the destination workbook the #NAME? issue comes back. I've even created a test destination spreadsheet and it doesn't suffer from the #NAME? problem. Any reason for this? Should I be worried about the integrity of some Sheets? Any advice greatly appreciated. Michael.

• Redirect websockets to port?

  - by DigitalMan

  So, I've got a WebSocket server in C++, that is a completely stand-alone entity - handles header parsing, receiving, sending, all of it on its own, listening directly to the port. Problem is, it needs to run on a server alongside Apache, and that's a bit of a problem. Now, there was a solution here to a similar issue involving mod_proxy, but I'm hoping I can intercept and redirect WebSocket communication before Apache even knows about it, possibly with iptables. So the question is, is it possible to direct traffic bound for chat.mysite.net to a WebSocket server on, say, port 8080, while anything else headed to mysite.net proceeds as expected to Apache?

• What data should I (can I) gather to prove a .net bug in third party software?

  - by gef05

  Our users are using a third-party system and every so often - a user might go all day without this happening, other days they may see it two or three times in seven hours - a red x will appear on screen rather than a button, field, or control. This is a .net system. Looking online I can see that this is a .net error. Problem is, our devs didn't write it, and the vendor wants proof that the problem resides with their system, not our PCs. What can we do to gather information on such an issue that would allow us to make our case to the vendor and get them to create a fix? I'm thinking of data to gather - anything from OS, memory. .net version installed etc. But I'd also like to know about error logging - if it's possible to log errors that occur in third-party systems.

• I think my computer is eating my USB devices

  - by user1068446

  Hi so I think the USB ports on the front of my desktop PC are eating all the devices that are plugged in. (I've found with a couple of USB disks I put at the start of the year, were then unusable on any device after wards). If this is the case, what's likely to be the problem, and how do I fix it? What would a good, simple way to diagnose the problem be? I'm a bit scared to put any of my USB devices in, because that sounds expensive. (I'm thinking I might look out for some cheap old disks).

• Is there any way to make an external monitor the primary under Boot Camp?

  - by mmc

  This may be a general problem for all Windows XP portables, I don't know, I don't have a dedicated Windows portable. I'm running a MacBookPro Unibody (so it's using the Nvidia 9600M chip under Windows XP SP2). Is there any way to get my external monitor to be the "main"? Even when I use the Nvidia Control Panel to move the task bar to my external monitor, games still refuse to run on anything other than the internal monitor. (In full screen mode, of course, if it's in a window, I can drag it to the other screen, no problem) I know I'm missing something elementary here.

• Debian virtual server hangs on reboot, need help debugging

  - by BubuIIC

  I'm admin of a Debian 6 virtual server. I've been trying to diagnose this problem for a while but haven't gotten anything. The server hangs every time I want to reboot it. All services seem to be shutting down, I lose ssh connection. Then nothing. I have to restart it through the hoster's web-interface, which just gives me the options "Normal Boot" and "Rescue System". Normal boot then brings the server back to life. Possibly (probably?) related, the server does not boot into a newer kernel version, it's running 2.6.18 right now, but installed is actually 2.6.32. I don't know whether it hangs on shutdown or on startup, but booting through the web-interface works (except the kernel part). Am I missing something obvious? Where should I start looking? I have no idea how to diagnose the problem.

• InnoDB table locks without apparent reason

  - by Skreo

  Hi, I have an InnoDB table for visitors' counting, which has perfectly worked for several years, but it failed twice yesterday, may be cause of the increase of visitors Without apparent reason, this table locked, with hundreds of DELETE an REPLACE INTO queries (+500) with "updating" or "cleaning up" status. (I've no more the copy of the processlist...) This table contains few entries, between 500 and 1500, so the updating queries are usualy very fast and don't lock. I don't know where I must search to find the cause of this problem and resolve it definitively. But I guess this could give you a better vision of the problem : mysql> show global status like "%innodb_row_lock%"; +-------------------------------+-----------+ | Variable_name | Value | +-------------------------------+-----------+ | Innodb_row_lock_current_waits | 0 | | Innodb_row_lock_time | 132004175 | | Innodb_row_lock_time_avg | 10521 | | Innodb_row_lock_time_max | 59373 | | Innodb_row_lock_waits | 12546 | +-------------------------------+-----------+ 5 rows in set (0.00 sec) Sorry for my poor english, and thanks for your help ;-)

  I'm using Linux Ubuntu 12.04 with curlftpfs to connect to a remote server. After mounting a remote ftp, opening and saving files with vim, list directories and files, for some time, after a while (no more of 30 minutes), with no reason it hangs. After opening other terminal tabs, all tabs remain iddle...but when using filezilla without restart the computer I still can get to the server and working with no problem. When using Nautilus, instead of curlftpfs, I'm having the same problem. After a while it hangs. Can anyone help me please?

• Entire folders deleted from My Documents periodically with remote logins

  - by darron

  I've got a customer who thinks our application is constantly deleting all it's data. It's really becoming a major problem for them. The problem is, there's no way it's us. They are losing not only our entire data folder (which we locate in the user's "My Documents" folder to make it easy to find), but some local settings files which are in entirely different places within the general user profile. It REALLY looks like the entire user is either getting reset, or is somehow synchronizing with a more... blank profile somewhere else. They're running this on some kind of virtualized Citrix guest OS. I see references to a "group policy folder redirection" that could do this... maybe roaming profiles? Any ideas? Help!

• Sony Vaio Sleep Mode

  - by someone11

  I have a problem with the sleep mode on Sony Vaio F Series and Windows 7 x64. If I wake it up by opening the lid and pressing power button everything works fine. However, if I wake it up on some other way (e.g. move the mouse), power light turns green and fan starts spinning, but LCD is dark and I cannot use keyboard (well, actually there is no sign that anyting works). Only thing I can do is to reboot it by pressing power button. Does anyone know what could be the problem?

• Why won't Windows XP 64 install on my machine?

  - by user272671

  I have a hp xw8200 workstation and would like to install Windowx XP 64 bit on it. Problem I seem to be having is when I reboot the machine and try to boot from the CD, nothing happens. Seems that the CD Drive is not being located or does not execute my cd to start the install. I already checked to verify that I can install Windows XP 64bit on my machine and also ensured I have the right bios and drivers for the install, only that the boot just does not take place. Anyone have any idea how I can solve this problem ? http://www.hp.com/workstations/pws/xw8200/xw8200.pdf http://h20331.www2.hp.com/Hpsub/cache/286710-0-0-225-121.html http://h20331.www2.hp.com/Hpsub/cache/286707-0-0-225-121.html thanks in advance

• TCP handshake ok, then the client isn't receiving any packets from the server

  - by infgeoax

  Topology: Client ----- Intermediate Device ----- Server Client: win7 Intermediate Device: unknown Server: CentOS 5.8 The problem occurs when the client and server are trying to establish a SSL connection. It happens to one specific port, 2000. I haven't been able to replicate the problem with other port numbers. I captured packets on both client and server. After the TCP handshake, from the client's perspective, it's not receiving ACKs for its previously sent packets so it kept re-sending them. On the server side, however, it did receive those packets and sent ACK packets. The weird thing is, after the server sent those ACKs, it received a [RST, ACK] packet, from the intermediate device, for every packet it sent. What could be the cause?

• One motherboard crashed. Changed and wants to crash again

  - by CoachNono

  My computer started to freeze randomly. I was pretty sure it was the hard drive that was starting to fail. Before I could change it, the motherboard was completely dead. I bought the same one and reinstall it. Everything went working well until my computer started to freeze again and doing the same problem has before. I don't want my motherboard to burn again and I'm really wondering what can be the problem... Could it be the power supply or the video cards that burned the motherboard ? I tested the voltages of the power supply and they seemed fine... The computer worked as is for four years... Here are the specs: ASUS P5N-D Motherboard LGA 775 NVIDIA 750i SLI Intel Q6600 2X EN9600GT 512mb 650w Corsair

• Pushing new mailbox limits for Exchange 2003 accounts

  - by Dobler

  There is this problem that I have every time I set up an account for a user on Exchange 2003. After I update the Mailbox limit to unlimited in the Exchange tab in the user preferences it does not seem to update right away. I remember reading somewhere that it takes several hours for the change to update in the database. I also remember typing in some terminal command that pushed the new updates immediately. What is that command, and why is it so difficult to find the answer to this problem on Google?

• IIS 7.5 Site being redirected from hostname to IP

  - by TuxOtaku

  So here's the problem. I have a site in IIS that is being redirected from the site's hostname to its IP address. The problem is, I haven't even set up redirects at all for the site; and yet when I analyze the headers that come through as the page loads, I see clear as day, "302 Temporary Redirect". What could be causing this? I thought perhaps it was something in my application's DB (it's a PHP/MySQL application), but I have ruled that out. I also thought that it might be a rewrite rule somewhere, so I deleted all my rewrite rules as well.
