• Cacti Login Page: Infinite loop occurs

  - by beicha

  Apache 2.2.3 | PHP 5.1.6 | MySQL 5.0.77 I followed cacti installation guide to install latest cacti 0.8.7h on CentOS 5.5 (64-bit). The installation of PHP/Apache/MySQL went smoothly until I finished the setup, and came to the login page. I can login http://.../cacti/index.php with admin account but the new page is redirected to the same login page with the message "Please enter your Cacti user name and password below" This is a infinite loop! If I use a wrong admin password I get the correct error message "Invalid User Name/Password Please Retype". [Same problem here] If I login use Guest/guest account, "Error: Access Denied, user account disabled." displays. The Cacti log file (./cacti/log/cacti.log) is empty. I Googled and seems this problem has existed for a long time, but no followup solutions were found on the forum posts I found. Anyone can help me on this problem? If more information needed, please let me know. Nov 18, 2011 UPDATE: I re-installed Cacti, this question remains UNSOLVED.

• How to pass Itemized Overlay from a class to a Listener Class.

  - by Taylor

  Hey guys, I tried searching the forums on this one, but I wasn't able to find anything on my problem. To describe my problem, everytime my location changes, it redraws the center maker on the map.... Only catch is that it doesn't delete the previous one. I can get it to delete the previous one when the location is changed, but I have no idea how to pass the original overlay in-between classes. Also, pastebin here Thanks in advance, hwrd

• Shapes-tool creating a vector mask every time, cannot seem to fix in CS3?

  - by Bryan

  Every time I create a shape using the shape tool, it places a vector mask on top of this. I don't know how I enabled this but it does not do it on my laptop version, only my desktop. I can seem to disable this problem I am having. Even reinstalling and restoring defaults I cannot seem to stop this. Very frustrating, anyone have a fix for this problem? Thanks in advance!

• Apache2.2 not responding or logging anything on Win 7

  - by Adam

  I'm having some trouble with Apache2.2 on Windows 7. For over a year it's been running no problem, but all of a sudden requests have just stopped responding. They don't time out as such, the browser just keeps on waiting forever. Nothing is recorded in either the error log (set to debug level), the access log, or Windows' Event Log. The problem showed up when I added a new VHost and restarted, however a syntax check has shown there's no problem with the config (from the little I changed), and the service does actually start error free. I've also disabled VHosts and tried with just localhost. I've tried to telnet to the web server, and it connects, but nothing happens. The prompt just goes blank and I can't type anything, and effectively become stuck. I've ensured there's a rule within Windows Firewall for Apache, and I've even disabled the entire thing just to check it wasn't the cause. Still the same. If I stop Apache however, the request fails immediately. I've uninstalled and reinstalled Apache, in the hope it might magically fix something using the default config, but still no joy. I've tried using a different port but nothing different. Does anybody have any suggestions to fix this? Or to perhaps try and figure out either if it's Apache itself not responding or something sitting between the two that's holding things up? I'm not too savvy on debugging Windows issues like this and I've been searching for hours but not found anything of use to me. Cheers Adam

• Computer keeps restarting [closed]

  - by Joris

  I have a strange problem with my desktop pc, when I start it, it just restarts immediately, it displays the bios/motherboard logo and then restarts. I can't access the bios to edit settings because it restarts to fast. Then I tried different things to fix it with mixed success. (I also tried to reset the bios without success) I noticed that a capacity from the graphics card was broken (it looked exploded) so I ordered a new graphics card & plugged it in the computer. It didn't change much, still the same problem. Then I unplugged everything that's not necessary and put only 1Gig RAM in the motherboard (usually it has 4 x 1Gig RAM) and the computer started, then I putted another gig of RAM and the computer still started. (starting=booting windows) When I putted in the 3th RAM it didn't boot anymore (again restarting all the time) so I removed this 3th gig of RAM and this is where it gets weird. I expected the computer to boot again because it is exactly the same configuration as before - which worked - but the computer didn't want to start. It just gave the same problem as before (restarting all the time.. ) Anyone an idea what might be wrong?

• mysql_connect "bool $new_link = true" is very slow

  - by Mikk

  Hi, I'm using latest version of Xampp on 64bit Win7. The problem is that, when I use mysql_connect with "bool $new_link" set to true like so: mysql_connect('localhost', 'root', 'my_password', TRUE); script execution time increases dramatically (about 0,5 seconds per connection, and when I have 4 diffirent objects using different connections, it takes ~2 seconds). Is setting "bool $new_link" to true, generally a bad idea or could it just be some problem with my software configuration. Thank you.

• Rendering a frame is producing noise from speakers in Windows and Linux

  - by Robber

  When any hardware accelerated application is rendering a frame (or many of them) a very short noise is coming from my speakers. This can be a game, a WebGL application or XBMC. When the application/game is rendering many frames per second (like most of them do) the noise is a continuous buzzing that gets higher pitched with higher framerates. This applies to Linux and Windows, so I'd assume it's a hardware problem. The current hardware in the PC is: CPU: Core2Quad Q9550 GPU: Radeon HD 5770 RAM: 2x2GB DDR2 Motherboard: Asus P5QLD PRO PSU: be quiet! Pure Power 530W Screen and speakers: Old 720p LCD TV connected via VGA and aux cable Muting the TV stops the noise, muting Windows doesn't. I tried replacing the PSU first (used a Tagan 700W PSU before) because I thought it was a power problem. It wasn't. I tried replacing the motherboard (used a ASUS P5B SE before) next because I thought it was a sound card problem. It wasn't. I tried the GPU in a different PC because I thought it was a broken graphics card. It worked perfectly fine in the other PC. I thought it might be interference, but moving the audio cable around changes absolutely nothing. I tried using an HDMI cable instead and that did work, but is not an option since my TV has only one HDMI input and I need that for my PS3.

• samba access from win98

  - by SimonSalman

  Hello, the admin installed a new file server in our institute: OpenSuse 11.1 with Samba 3.2.7-11.3.2-2154-SUSE-CODE11. They copied the smb.conf from the old machine (hosting Samba 3.0.0) to the new one. Everything works as before, but one Windows 98 machine can see but not access the file server. It prompts for user authentication, but will not accept any user-password combination. There exists a lot of discussion about the problem on the net, but none provided a clear answer to the problem. EDIT: 1. I changed Win98 registry enable plain-text passwords, and alternatively changed server's smb.conf and /etc/smbpasswd to accept encrypted passwords 2. Further I provide a profile with a user-password combination on Win98 machine similar to one of the samba users-password combinations. 3. I changed smb.conf such that the samba server is the Local Master Browser all these changes are not necessary when using the older samba server. So, I conclude that a configuration problem on the server side is likely. If you need any further information, I will post them here. Best regards, Simon

• How to disable monitor auto detection in Windows 7?

  - by Jay Yother

  I am currently running Windows 7 Ultimate 64-bit with a dual monitor setup with an NVIDIA 7950 GT graphics card. One monitor is dedicated to this machine and the other monitor is connected to a DVI KVM switch. When I switch to my other computer, Windows 7 disables the monitor. However, when I switch back it does not re-enable the monitor. The only circumstance that automatically re-enables the second monitor is when I switch back after Windows has put the monitors into power save mode. I am continually having to bring up the NVIDIA control panel to have it re-enable the monitor. Under Windows XP I would just disable the NVIDIA service to prevent it from auto-detecting the monitor (which doesn't solve the problem under Win7), and in Vista there was a registry hack that would prevent this. It looks as though that has been removed in Windows 7. I have found similar questions posted on this site, but nothing that matches my problem exactly. The following link is the question that comes the closest, but does not provide a solution to the problem. http://superuser.com/questions/96683/how-to-fix-monitor-detection-on-windows-7 Is there a way in Windows 7 to disable monitor auto-detection? Update: I just added a second graphics card to my Windows 7 64-bit machine. I plugged one monitor into each graphics card. Now, when I use the KVM switch to switch back and forth it will re-enable the second monitor like it should. There are however, a few quirks with this. If I have a program maximized on the second monitor and it has focus, when I switch it will move to monitor 1. If I have a program maximized on the second monitor and it does not have focus, when I switch it will behave like it is minimized and when I bring it back up it will show up maximized on monitor 1. Definitely better than it was, but still looking for a way to disable the auto-detection.

• Excel table auto update

  - by Mike

  So I have a table in Excel with formulas. When I add a new row, the new row automatically fills in the formulas as well, which is great. My problem is that it also changes the formula in the row above the added row as well. Here's what happens specifically: My table's last row is row 24. A formula I have in that row is the following: =COUNTIF(C$11:C24,"y")/(COUNTIF(C$11:C24,"Y")+COUNTIF(C$11:C24,"N")) When I add in data in row 25 the formula is updated in row 25 as well, which is what I want, to the following: =COUNTIF(C$11:C25,"y")/(COUNTIF(C$11:C25,"Y")+COUNTIF(C$11:C25,"N")) My problem is that the row above also updates - my row 24 changes to the same as row 25 (the C24 goes to C25). Why is my row 24 formula changing when I add a row 25? Note, my formulas above row 24 stay the same when I add in row 25 - only row 24 changes when I add in 25. Is there a way to not update the row above the row being added? This problem continues when additional rows are added - If I add in a row 26, then the formula in rows 24-26 then all reference C26. Why are they all updating?

• Can't detect hard drive on Macbook Pro

  - by MartinMoizard

  I changed a few month ago the config of my Macbook Pro with the following: I bought a SSD hard drive I removed the hard drive of my Mac book Pro and installed there my brand new SSD Then I removed my DVD drive and installed my hold hard drive instead with a caddy Everything was working great until today when I couldn't access anymore to my old hard drive because it is not detected anymore. Sometimes Mac OSX is mounting it but it takes like 15 min to browse a simple folder. I opened my laptop to have a look at the problem. It seemed like the optical drive connector was not plugged correctly to the motherboard (that connector: http://cl.ly/2T0X2e1j0J1g47061d1t). So I plugged it correctly and reboot. It didn't fix my problem. Then I tried to put my SSD in the caddy and to boot: no hard drive was detected. So I guess there is something wrong either with the caddy, either with the optical drive connector, or either with the plug that is on the motherboard. So my question is, how can I know where the problem comes from?

• Using jquery to prevent resubmitting form

  - by Tony

  I use jquery's .submit() to intercept user's submit event, however I found a problem. When the user single click the submit button, the form is submitted normally, but if a user deliberately fast click it multiple times, it will submit multiple times, which will cause duplicated data in the database. What's the solution for this kind of problem ?

• VPS goes slow at more than 20 users online at the same time

  - by hachiari

  I have 512 MB VPS (brustable to 1GB) Somehow, the site goes slow when there are about 10 users, and becomes impossible to load at 20 users online at the same time. I wonder what could be the problem for this. The bandwidth connection of the VPS is 1Gbps. Here is some settings in my VPS: KeepAlive Off <IfModule prefork.c> StartServers 7 MinSpareServers 7 MaxSpareServers 10 ServerLimit 64 MaxClients 64 MaxRequestsPerChild 0 </IfModule> my.cnf settings - calculated Max Memory 300MB Output from UNIXBENCH INDEX VALUES TEST BASELINE RESULT INDEX Dhrystone 2 using register variables 376783.7 13429727.4 356.4 Double-Precision Whetstone 83.1 1137.5 136.9 Execl Throughput 188.3 1637.4 87.0 File Copy 1024 bufsize 2000 maxblocks 2672.0 148868.0 557.1 File Copy 256 bufsize 500 maxblocks 1077.0 79430.0 737.5 File Read 4096 bufsize 8000 maxblocks 15382.0 1410009.0 916.7 Pipe Throughput 111814.6 4419722.0 395.3 Pipe-based Context Switching 15448.6 561505.1 363.5 Process Creation 569.3 10272.7 180.4 Shell Scripts (8 concurrent) 44.8 514.3 114.8 System Call Overhead 114433.5 3537373.8 309.1 ========= FINAL SCORE 295.0 I am afraid that the VPS company limit the number of connection to the VPS... is it possible? The server is in Japan, but the site has global traffic (some of the traffic are from countries with low speed connection). Could this be the problem? This is a serious problem :( my site just cant grow if this keeps on happening... please tell me if you have any idea. Thank You, Bryant

• A switch and router between the printer and PC that want to print but cannot

  - by Robert Memo

  IP 192.168.1.5 has a wireless connection to a Linksys router (192.168.1.1) which then is connected to a switch. The switch is connected to a server (192.168.0.2). My printer has IP address of 192.168.0.8. Internet connection is fine on 192.168.1.5. Problem 1: IP 192.168.1.5 can not print using printer 192.168.0.8. Problem 2: IP 192.168.1.2 can not access a shared folder on the the server. The reason for connecting this way is that, the server does not release wireless signal. In order to get wireless signal the Router is connected to the switch. The server is a computer server that only has one outgoing LAN port. Plus, due to inconvinience physical locations, I do not have option to change the physical locations and the way it is connected already. I just want the labtops that only have wireless connection to communicate with the printer and the server. I have tried to change the router IP address to 192.168.0.x like the server and printer. It caused problem for the laptop. The router no longer release internet signals. The router does have IP address from the server 192.168.0.5.

• Sending email with exim and external sender address

  - by Tronic

  hi. i have following problem: i want to send emails with an rails webapp. i set up an exim server and when looking into the logs, the sending works, but the emails aren't sent really. i had the same problem with another isp. the sender address is hosted on another mailserver, other isp. i think the problem is, that sending doesn't work because the sener address isn't hosted on the same server. do you have any advice on this? the logs (exim) tell me the following: 2011-01-01 14:38:06 1PZ1eo-0000Ga-38 <= <> R=1PZ1eo-0000GY-1p U=Debian-exim P=local S=1778 2011-01-01 14:38:08 1PZ1eo-0000Ga-38 => [email protected] R=dnslookup T=remote_smtp H=mx1.emailsrvr.com [98.129.184.131] X=TLS1.0:RSA_AES_256_CBC_SHA1:32 DN="C=US,O=mx1.emailsrvr.com,OU=GT21850092,OU=See www.geotrust.com/resources/cps (c)08,OU=Domain Control Validated - QuickSSL(R),CN=mx1.emailsrvr.com" 2011-01-01 14:38:08 1PZ1eo-0000Ga-38 Completed [email protected] is the external sender-address! thank you!

• Why catch Exceptions in Java, when you can catch Throwables?

  - by corfield

  Hi We recently had a problem with a Java server application where the application was throwing Errors which were not caught because Error is a separate subclass of Throwable and we were only catching Exceptions. We solved the immediate problem by catching Throwables rather than Exceptions, but this got me thinking as to why you would ever want to catch Exceptions, rather than Throwables, because you would then miss the Errors. So, why would you want to catch Exceptions, when you can catch Throwables?

• Windows Explorer Keeps On Crashing

  - by Josefvz

  Hey Folks. I'm lost... I'm using Windows 7 Ultimate 64bit. My Pc is up to date(windows updates) and I've used Winutilities to scan my registry. My explorer.exe keeps on crashing. Just randomly it seems. I don't even need to be doing anything particular. I do have experience with pc in general as I'm a software developer. I know you will require additional info, but i don't know what, so just leave a comment and I'll update. Additional info I think i should also mention that explorer is the only app that crashes on my pc. The crash report i got now: Description: A problem caused this program to stop interacting with Windows.

• Computer randomly shuts itself off

  - by Decency

  I have not been able to determine a pattern for why this happens, despite my best efforts. I've attempted to run it on full power with Prime95 and this doesn't trigger a restart. Generally the restarts occur while I'm playing games, watching videos, or even just having multiple tabs open in a browser. However, I often play processor intense games for hours without any restarts occurring, and sometimes they'll happen 3-4 times in an hour during less intense activity, so I don't think that is the problem. I imagine it has something to do with overheating or power consumption so I've been monitoring CPU temperature and cleaning with compressed air, but the problem keeps happening. I don't know how to track power consumption, and assume that this is the problem. Whenever this occurs, the sound gets stuck in a short loop of whatever was playing at the time, though restarts also occur when nothing is playing. Here is a screenshot of temperatures: and under load: Here's the parts list: http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=10546754 As shown in the list, the case includes a 585W Power Supply, which I've been told should be plenty. I built the computer myself with a friend's guidance but it's very possible I did something wrong. Right now I'm looking into ensuring that I have the latest drivers for all components. Any help would be appreciated- thanks.
