• Help with memory usage issues on VPS

  - by Niall Collins

  Hi there, I am running a VPS server with 6 .net web sites/applications running on it. I am having issues with performance on the server, mainly it running out of memory. I contacted the company that lease the server to me and they told me it was because I also had sql server 2008 express also running on the server. So I went ahead and removed this, uninstalled etc. However I still seem to be having issues. For example at present, looking at resource consumption, the virtual memory is: ID: vprvmem Current Use: 894,328,832 bytes Limit: 1,073,741,824 bytes This means useage of ~80%. Is there any way I can check out exactly that applications, web sites, software is taking up most of the servers memory, so I can look at rectifying it. I feel that 80% is much to high to allow for contingency for a spike in traffic. I have got extra memory resources added to the box recently, but I would prefer finding the source of the problem rather than throwing extra memory at it. Maybe these levels are correct and alls running ok, but would like to investigate it to make sure. My knowledge of hardware is limited as I mostly deal in the spectrum of software. So any tools out there that can help me or any pertient advice.

• rsnapshot schedule overlapping, help with backup schedule

  - by Znarkus

  Hello, I have to following configuration. rsnapshot.conf interval halfhourly 4 interval hourly 6 interval twohourly 12 interval daily 7 interval weekly 4 crontab 0,30 * * * * /usr/bin/rsnapshot halfhourly >> /var/log/rsnapshot.halfhourly.log 2>&1 5 * * * * /usr/bin/rsnapshot hourly >> /var/log/rsnapshot.hourly.log 2>&1 10 */2 * * * /usr/bin/rsnapshot twohourly >> /var/log/rsnapshot.twohourly.log 2>&1 15 3 * * * /usr/bin/rsnapshot daily >> /var/log/rsnapshot.daily.log 2>&1 20 6 * * MON /usr/bin/rsnapshot weekly >> /var/log/rsnapshot.weekly.log 2>&1 Only halfhourly is running correctly now. hourly spits out this error: rsnapshot encountered an error! The program was invoked with these options: /usr/bin/rsnapshot hourly ---------------------------------------------------------------------------- ERROR: Lockfile /var/run/rsnapshot.pid exists and so does its process, can not continue To me it seems like my 5 min space between halfhourly and hourly is too small. Is this configuration crazy? I like having backups every thirty minutes, that will probably save my ass some day. Please help me make a decent backup schedule, that doesn't clog up the system, but creates frequent enough backups. Thank you.

• Need Corrected htaccess File

  - by Vince Kronlein

  I'm attempting to use a wordpress plugin called WP Fast Cache which creates static html files from all your posts, pages and categories. It creates the following directory structure inside wp-content: wp_fast_cache example.com pagename index.html categoryname postname index.html basically just a nested directory structure and a final index.html for each item. But the htaccess edits it makes are crazy. #start_wp_fast_cache - do not remove this comment <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_METHOD} ^(GET) RewriteCond /home/user/public_html/wp-content/wp_fast_cache/%{HTTP_HOST}%{REQUEST_URI}x__query__x%{QUERY_STRING}index.html -f RewriteCond %{HTTP_USER_AGENT} !(iPhone|Windows\sCE|BlackBerry|NetFront|Opera\sMini|Palm\sOS|Blazer|Elaine|^WAP.*$|Plucker|AvantGo|Nokia) RewriteCond %{HTTP_COOKIE} !(wordpress_logged_in) [NC] RewriteRule ^(.*)$ /home/user/public_html/wp-content/wp_fast_cache/%{HTTP_HOST}%{REQUEST_URI}x__query__x%{QUERY_STRING}index.html [L] RewriteCond %{REQUEST_METHOD} ^(GET) RewriteCond %{QUERY_STRING} ^$ RewriteCond /home/user/public_html/wp-content/wp_fast_cache/%{HTTP_HOST}%{REQUEST_URI}index.html -f RewriteCond %{HTTP_USER_AGENT} !(iPhone|Windows\sCE|BlackBerry|NetFront|Opera\sMini|Palm\sOS|Blazer|Elaine|^WAP.*$|Plucker|AvantGo|Nokia) RewriteCond %{HTTP_COOKIE} !(wordpress_logged_in) [NC] RewriteRule ^(.*)$ /home/user/public_html/wp-content/wp_fast_cache/%{HTTP_HOST}%{REQUEST_URI}index.html [L] </IfModule> #end_wp_fast_cache No matter how I try and work this out I get a 404 not found. And not the Wordpress 404, and janky apache 404. I need to find the correct syntax to route all requests that don't exist ie: files or directories to: wp-content/wp_fast_cache/hostname/request_uri/ So for example: Page: example.com/about-us/ => wp-content/wp_page_cache/example.com/about-us/index.html Post: example.com/my-category/my-awesome-post/ => wp-content/wp_fast_cache/example.com/my-category/my-awesome-post/index.html Category: example.com/news/ => wp-content/wp_fast_cache/example.com/news/index.html Any help is appreciated.

• Cisco Spam Blocker, Iron Port, Lotus Domino, Integration Help

  - by NickToyota

  Hi serverfault universe, I work for a medium sized (roughly 200 user) company. We are attempting to intagrate our new Cisco Spam Video Blocker (ironport) device into our network so that it acts as an incoming filter then passes it off to our Lotus domino mail server. And also vise versa. The way our network is setup currently has an mx record pointing to our Domino mail SMTP incoming server which is currently setup to be an inbound gateway and filter (using symantec domino mail software). We want to replace the inbound gateway with the ironport. Our company has also invested in a pool of external IP addresses which I believe has been currently assigned to our web, email, servers. What would the proper course of action be to successfully integrate the device be? Mx record change? Replace the domino gateway completely with the ironport? We attempted to set the ironport device to the external IP of what our mx record is pointing to without much success. Any help on proper setup would be greatly appreciated.

• Help setting up an secondary authoritative DNS server.

  - by GLB03

  We have three Authoritative DNS servers and three recursive/caching DNS servers on my campus. Authoritative servers DNS1- Windows 2003 DNS2- Old Red Hat ----- Replacing w/ newer version DNS3- Windows 2008 (I installed) Caching and Recursive resolvers servers Server1- Windows 2003 Server2- CentOS 5.2 (I installed) Server3- CentOS 5.3 (I installed) I am replacing DNS2 with a newer Red Hat version, but have no documentation on how it was implemented. I have setup caching and windows authoritative servers, but not a linux secondary authoritative server. I have a perl script from the original server that pulls data from our DNS1 server. We use DJBDNS and TinyDNS on our linux servers. Our Network Engineer says the DNS2 server I am replacing is an authoritative server that doesn't need to be caching, but the only instructions I see is for an Authoritative server that does caching as well. Can someone point me in the right directions. I thought I was on the right track with using these instructions but when I query my new dns server I get "No response from server", I have temporarily disabled iptables to eliminate it from being an issue. ps -aux | grep dns avahi 3493 0.0 0.2 2600 1272 ?

• Registry remotley hacked win 7 need help tracking the perp

  - by user577229

  I was writing some .VBS code at thhe office that would allow certain file extensions to be downloaded without a warning dialog on a w7x32 system. The system I was writing this on is in a lab on a segmented subnet. All web access is via a proxy server. The only means of accessing my machine is via the internet or from within the labs MSFT AD domain. While writing and testing my code I found a message of sorts. Upon refresing the registry to verify my code changed a dword, instead the message HELLO was written and visible in regedit where the dword value wass called for. I took a screen shot and proceeded to edit my code. This same weird behavior occurred last time I was writing registry code except on another internal server. I understand that remote registry access exists for windows systems. I will block this immediately once I return to the office. What I want to know is, can I trace who made this connection? How would I do this? I suspect the cause of this is the cause of other "odd" behaviors I'm experiencing at work such as losing control of my input director master control for over an hour and unchanged code that all of a sudden fails for no logical region. These failures occur at funny times, whenver I'm about to give a demonstration of my test code. I know this sounds crazy however knowledge of the registry component makes this believable. Once the registry can be accessed, the entire system is compromised. Any help or sanity checking is appreciated.

• mod rewrite help

  - by Benny B

  Ok, I don't know regex very well so I used a generator to help me make a simple mod_rewrite that works. Here's my full URL https://www.huttonchase.com/prodDetails.php?id_prd=683 For testing to make sure I CAN use this, I used this: RewriteRule prodDetails/(.*)/$ /prodDetails.php?id_prd=$1 So I can use the URL http://www.huttonchase.com/prodDetails/683/ If you click it, it works but it completely messes up the relative paths. There are a few work-arounds but I want something a little different. https://www.huttonchase.com/prod_683_stainless-steel-flask I want it to see that 'prod' is going to tell it which rule it's matching, 683 is the product number that I'm looking up in the database, and I want it to just IGNORE the last part, it's there only for SEO and to make the link mean something to customers. I'm told that this should work, but it's not: RewriteRule ^prod_([^-]*)_([^-]*)$ /prodDetails.php?id_prd=$1 [L] Once I get the first one to work I'll write one for Categories: https://www.huttonchase.com/cat_11_drinkware And database driven text pages: https://www.huttonchase.com/page_44_terms-of-service BTW, I can flip around my use of dash and underscore if need be. Also, is it better to end the URLs with a slash or without? Thanks!

• Help trying to figure out why IIS7 is crashing / locking up / denying connections

  - by Pure.Krome

  Hi folks, I've got a pretty busy website that is running on a single web front end machine, on W2K8 + IIS7. Every now and then - eg. maybe monday at 3am or something, then a few days later .. some early morning time .. then nothing for 2 weeks ... etc - the website fails to respond to any client connections. ie. no one can connect to the website. I can remote desktop to the machine, etc no probs. I restart the app pool (the website is running in intergrated mode), still nothing. I try and get a crash dump of the process (it's around 600 mb maybe even more) ... that fails after about a min of trying (and i have plenty of HD space). The only way to fix this issue, is to manually stop the www service and then start it again. The stopping takes a while (a minute?) while starting is nearly instant. I'm at a loss to figure out what part of my code is causing this. At first, I thought it might be a stack overflow because of some error that might be going to the error page, which in turn errors .. rinse repeat boom. But i've had a look at the error page and it feels ok. So, I'm hoping someone might be able to help and say how I can correctly get a proper dump of the IIS process so i can then do some more autopsy on it. I would email Tess Ferrandez (the goddess of crash debuging) but I thought I'd try here before I spam her. Can anyone have any suggestions to how I can figure out how to start to debug this issue?

• Help with Ubuntu and Windows, separate HDs

  - by LuxuryMode

  Need some major help. Running a Dell XPS/Dimension 630i. It came with "SATA 2 RAID 0 With Dual 500GB Hard Drives." I have installed a new, third non-raided drive and installed Ubuntu on it. So now I have Windows on the original hard drive and Ubuntu Linux on the new HD. When I get to the boot menu where I can select an OS, if I select windows I get an error: "No such drive, no such disk." Also, strangely in the first place, in order to even get to the bootloader menu I have had to disable ALL ports under the RAID config. Unless I do this, I will just get to a never-ending blinking cursor. I have tried every conceivable CMOS config and nothing else works. Tried setting port 3 (the new HD w/ Ubuntu) to first hard disk boot priority. Tried disabling all other ports and enabling the Ubuntu HD port and vice versa. I have some pictures of boot up: first one is strange error i get after messing with CMOS to finally get ubuntu install to work. http://imgur.com/5sqJa then boot menu: http://imgur.com/TWtLq then error: http://imgur.com/TJ1mS. Also, please note that I can actually access all files from the raided Windows drive through Ubuntu.

• Need to restore emails that Outlook deleted from the mail server

  - by Mugen

  I wanted to use POP mail for my Yahoo mail account. So I went to the Yahoo mail settings and enabled POP feature. I installed Microsoft Outlook 2007 and added the settings for my Yahoo mail account. Then I performed a sync. I successfully received all the emails from Yahoo account into my pc. But when I logged into my Yahoo mail online, to my horror all the mails were deleted. It seems someone in Microsoft for some reason decided to keep the default setting unchecked for "Leave copy of messages on the server". This has been a very old account and I need to have all the mails also present on the mail server so I can access it anytime and future purposes. Is there anyway I can restore these emails on the server again? Any ideas how I can get it back to the way it was? I have been googling this for quite sometime now but I'm not able to find it. Any helpful suggestions are welcome. Thanks.

• How to handle files that don't need version control in mercurial

  - by richardh

  I am new to mercurial, and for the most part do LaTeX reports and statistical calculations in R using .csv and/or .sqlite files. Re LaTeX, all I really care is the .tex file. Re R, I don't need version control on the .csv or .sqlite files because they are static. When I do 'hg add' for a repo with a .csv and/or .sqlite file, I get a warning like: rev2.sqlite: up to 3070 MB of RAM may be required to manage this file (use 'hg revert rev2.sqlite' to cancel pending addition) So I revert and subsequently use adds like hg add -X *.sqlite. I guess I really have two questions: (1) Should I ignore these warnings? Because these large files are static, can I just add to the repo knowing that the diff files will always be empty and not worry about wasted resources? (2) If I should keep excluding these files from the repo, is there away that I can fix this option? I.E., add to my .hgrc file something that always appends an option like -I *.tex -I *.R to my 'hg add' commands? Thanks!

• Mac OS X in Virtualbox says "You need to restart your computer"

  - by humoeba

  I've been trying to figure out for the past week how to get Snow Leopard reliably running in a VM. Right now I am using VirtualBox, and it runs fine for a while, but every once in a while (happened 3 times in the last few hours) I get the "You need to restart your computer" message. Unfortunately, it hasn't even lasted long enough to finish installing the operating system yet. I first tried VMWare, which was a pain to set up. I got it running ok, operating system installed, with the guest tools. Every once in a while though, it just stops running. I click inside the VM, and there's no mouse. It doesn't respond to keyboard input either. I have to reset the VM to get a response. I'm wondering if this is the same error. This happens with both Workstation and Player. Here is the tutorial I used for VirtualBox: http://www.sysprobs.com/iboot-loader-virtualbox-install-snow-leopard Here's the tutorial I used for VMWare: http://bobhood.wordpress.com/2009/12/18/welcome-to-snow-leopard-mac-os-x-10-6-and-vmware-workstation-7/ I'm using an iso for Mac OS X 10.6.3. I have an HP Pavilion dm4 with an Intel Core i7 M640 running Windows 7; VT is turned on. Using VirtualBox 4.0.4 and VMWare Workstation 7.0.1 and VMWare Player 3.0.1 Does anyone know what might be causing this error or how I can fix it? Thanks.

• I need a driver for my Cardbus USB 2.0 card

  - by Carl

  The picture and details of the card are here: http://www.ht-link.com/en/ProductView.asp?ID=106 The Windows drivers for this don't work right. I tried them on my previous laptop, and then installed the ones off their included CD. (Note that the systems requirements includes a CD-ROM drive...) I have a new laptop, and lost the CD. The website that lists the drivers is broken - the download links don't work. It is here: http://www.ht-link.com/en/DownView.asp?ID=10 I need the very first link - The Win XP drivers for the HT-112NEC. The company does not reply to my e-mails. I've tried searching Google for other sources for the driver (I didn't bother with those sites that want me to install driver detection software or create a log-in for their site). [Here's the problem I am getting using the drivers Windows XP SP3 installs: When I plug in my USB 2.0 hard-disk adapter, a USB Mass Storage Device entry is added in the Device Manager, but there is no entry under Disk Drives, and a drive letter is not assigned, so I can't access the driver. Like I said, this card didn't work without their special drivers on my other laptop, either.]

• explanation of RAM specs, and what do I need for a Gaming rig

  - by ewok

  I am looking into upgrading my custom built PC's RAM. I use the machine mostly for gaming, but I don't really know a ton about RAM, so I wanted to ask a few questions. The research I've done tells me there is a negligible increase in speed for anything above 1600 MHz. is this true or is it worth the extra money to go higher? Other than drawing more power from the PSU, is there any real difference in performance with different voltages (1.5V vs 1.65V)? most of the kits I've found in the 2x4 1600 range have a CAS latency of 9 and timing of 9-9-9-24. For a significant increase in price (usually about 1.5x), I can get either 8 or 7 and lower timing. Is it worth the cost? What I am looking for here is someone to give a good explanation of what the different specs represent, and how that relates to the performance of the machine. Specifically, I'm looking for what specs I need to focus on for a good gaming rig. I am NOT looking for a "buy this, it's the best RAM" without an explanation of why. The information will be much more valuable as it will allow me to make my own informed decision. As they say, give a man a fish, he'll eat for a day. teach a man to fish, and he'll eat for the rest of his life.

• P2V Wouldn't Boot, Rebuilt initrd, Need to Clean Up

  - by Mike Soule

  We have a CentOS 5.4 server (build 2.6.18-164.el5xen). We went to P2V this server so we can have redundancy, the physical only has one PSU. The P2V only completed 99% of the way, we have a VMWare ticket opened, but they marked the ticket as low priority. I was able to boot into a rescue disc of Red Hat 5.4 and rebuild the initrd with the help of this blog post. Now the only issue is the original server had a modified initrd, which was also from a different OS build and made by an outside provider. We do not have a document outlining modifications. My question is, is it at all possible to copy the initrd off of the physical server and replace it on the virtual and some how have the virtual machine boot? Thanks for any input. Edit: I copied the initrd img from the physical and it recreated the original issue. Here is a screen capture of the error. http://i.imgur.com/MqC73.jpg Edit2: echo Scanning logical volumes lvm vgscan --ignorelockingfailure echo Activating logical volumes lvm vgchange -ay --ignorelockingfailure VolGroup00 resume /dev/VolGroup00/LogVol01 echo Creating root device. mkrootdev -t ext3 -o defaults,ro /dev/VolGroup00/LogVol00 echo Mounting root filesystem. mount /sysroot

• IPTables configuration help

  - by Sam

  I'm after some help with setting up IPTables. Mostly the configuration is working, but regardless of what I try I cannot allow localhost to access the local Apache only (i.e. localhost to access localhost:80 only). Here is my script: !/bin/bash Allow root to access external web and ftp iptables -t filter -A OUTPUT -p tcp --dport 21 --match owner --uid-owner 0 -j ACCEPT iptables -t filter -A OUTPUT -p tcp --dport 80 --match owner --uid-owner 0 -j ACCEPT Allow DNS queries iptables -A OUTPUT -p udp --dport 53 -j ACCEPT iptables -A OUTPUT -p tcp --dport 53 -j ACCEPT Allow in and outbound SSH to/from any server iptables -A INPUT -p tcp -s 0/0 --dport 22 -j ACCEPT iptables -A OUTPUT -p tcp -d 0/0 --sport 22 -j ACCEPT Accept ICMP requests iptables -A INPUT -p icmp -s 0/0 -j ACCEPT iptables -A OUTPUT -p icmp -d 0/0 -j ACCEPT Accept connections from any local machines but disallow localhost access to networked machines iptables -A INPUT -s 10.0.1.0/24 -j ACCEPT iptables -A OUTPUT -d 10.0.1.0/24 -j DROP Drop ALL other traffic iptables -A OUTPUT -p tcp -d 0/0 -j DROP iptables -A OUTPUT -p udp -d 0/0 -j DROP Now I have tried many permutations and I'm obviously missing everything. I place them above the in/out bound SSH to/from, so it's not the precedence order. If someone could give me the heads up on allowing only the local machine to access the local web server, that'd be great. Cheers guys.

• Help in recovering partition

  - by goshopedero

  Okay so i had one NTFS partition and i wanted to resize it, but while resizing it with partition magic some error occurred and now i am not able to enter in my partition anymore. I have slackware 13 also and i tried mounting the partition from there but it didn't succeed. One friend of mine came to my house with some live-cd os called backtrack3 and when he booted from cd, he was able to mount the damaged partition - and was able to read/write on it anywhere. I saw my files, they are all there, so nothing's erased just the partition is somehow damaged. But strange thing was that from backtrack we weren't able to mount some of the working partitions of my comp, and we could mount the damaged one. So i am asking for some help here: My files are all there, and i saw them from backtrack. What can i do to fix the partition so it would be usable from windows/slackware again ? Please tell me anything you've got because i have some important data on it. Thank you.

• I really need help resolving a Window Vista BSOD (Blue Screen Crash) on my desktop

  - by anonymous

  Hi, thanks for taking the time to read this. I'll get straight to the details. My desktop is on the fritz; it keeps going to blue screen with the stop message of 0x0000007E immediately after the loading bar of vista, right before transitioning to the account selection screen. My desktop runs on a dual-core 32-bit processor with windows Vista Home(?) installed. I have 3 GB of ram as two separate modules, a 1GB acer module and a 2GB geil module. I have an ati video card, unfortunately I cannot recall the exact name but the chipset is ATI and the manufacturer is Sapphire and the card is on the lower end. My hard drive is 320GB (i think) partitioned into two. The C:\ partition is red lined, while the D:\ partition is still pretty empty. As per the advice of my friend, i tried restarting the system with the graphics card removed. Upon failure, i repeated the process removing one RAM module one at a time, but the system still failed to load. Vista would attempt to repair the system and it would initially report that the system was fixed, but vista really failed to fix the problem. After removing the memory modules, vista started to report it's inability to fix the problem. I tried running on safe mode and the driver listing would always stop at crcdisk.sys. I ran memory diagnostics using the windows memory diagnostic tool found in the screen after vista's failed attempt to fix the problem with no luck. the problem details are as such: Problem Event Name : StartupRepairV2 Problem Signature 01: AutoFailover 02: (vista's version number?) 03: 6 04: 720907 05: 0x7e 06: 0x7e 07: 0 08: 2 09: WrpRepair 10: 0 OS Version: 6.0.6000.2.0.0.256.1 Locale ID 1033 any correct advice would be appreciated as i really need my pc to work so i can work on my projects. kinda sad, but i'm college of computer science and i have no idea what to do :P

• Help with Windows 7 BSOD with windbg minidump !analyze -v results

  Hi gang, Windows 7 X64 Ultimate is BSODing occasionally. I suspect an overheating issue or something related to the use of my GTX-295 card that runs very hot. Here is an !analyze -v listing of the most recent minidump. Any and all help greatly appreciated. Kurt Microsoft (R) Windows Debugger Version 6.12.0002.633 AMD64 Copyright (c) Microsoft Corporation.

• Need help making site available externally

  - by White Island

  I'm trying to open a hole in the firewall (ASA 5505, v8.2) to allow external access to a Web application. Via ASDM (6.3?), I've added the server as a Public Server, which creates a static NAT entry [I'm using the public IP that is assigned to 'dynamic NAT--outgoing' for the LAN, after confirming on the Cisco forums that it wouldn't bring everyone's access crashing down] and an incoming rule "any... public_ip... https... allow" but traffic is still not getting through. When I look at the log viewer, it says it's denied by access-group outside_access_in, implicit rule, which is "any any ip deny" I haven't had much experience with Cisco management. I can't see what I'm missing to allow this connection through, and I'm wondering if there's anything else special I have to add. I tried adding a rule (several variations) within that access-group to allow https to the server, but it never made a difference. Maybe I haven't found the right combination? :P I also made sure the Windows firewall is open on port 443, although I'm pretty sure the current problem is Cisco, because of the logs. :) Any ideas? If you need more information, please let me know. Thanks Edit: First of all, I had this backward. (Sorry) Traffic is being blocked by access-group "inside_access_out" which is what confused me in the first place. I guess I confused myself again in the midst of typing the question. Here, I believe, is the pertinent information. Please let me know what you see wrong. access-list acl_in extended permit tcp any host PUBLIC_IP eq https access-list acl_in extended permit icmp CS_WAN_IPs 255.255.255.240 any access-list acl_in remark Allow Vendor connections to LAN access-list acl_in extended permit tcp host Vendor any object-group RemoteDesktop access-list acl_in remark NetworkScanner scan-to-email incoming (from smtp.mail.microsoftonline.com to PCs) access-list acl_in extended permit object-group TCPUDP any object-group Scan-to-email host NetworkScanner object-group Scan-to-email access-list acl_out extended permit icmp any any access-list acl_out extended permit tcp any any access-list acl_out extended permit udp any any access-list SSLVPNSplitTunnel standard permit LAN_Subnet 255.255.255.0 access-list nonat extended permit ip VPN_Subnet 255.255.255.0 LAN_Subnet 255.255.255.0 access-list nonat extended permit ip LAN_Subnet 255.255.255.0 VPN_Subnet 255.255.255.0 access-list inside_access_out remark NetworkScanner Scan-to-email outgoing (from scanner to Internet) access-list inside_access_out extended permit object-group TCPUDP host NetworkScanner object-group Scan-to-email any object-group Scan-to-email access-list inside_access_out extended permit tcp any interface outside eq https static (inside,outside) PUBLIC_IP LOCAL_IP[server object] netmask 255.255.255.255 I wasn't sure if I needed to reverse that "static" entry, since I got my question mixed up... and also with that last access-list entry, I tried interface inside and outside - neither proved successful... and I wasn't sure about whether it should be www, since the site is running on https. I assumed it should only be https.

• Possible capacitor plague - need help identifying

  - by cornjuliox

  I've been having some PC power issues lately, and I think I've tracked it down to a bad power supply. Lately, when I'm on my PC it will often restart without warning, displaying "Hypertransport sync flood error occurred last boot." once POST finishes. I've googled the error, but can't come to a definitive conclusion as to what's causing it. I've seen posts suggesting that it might be a power supply issue, but nothing conclusive. Here's what I've done so far: -I haven't installed anything suspect within the last 3 months. -I do overclock just a tiny bit, so I tried raising the voltages a little. That didn't work so I brought both CPU multiplier and voltages all back to their default settings, but that didn't solve the problem either. The problem still occurs. -AV scanned the whole system, nothing suspect. -I suspected that it might be a bad power supply so I cracked that open and found the following: I think it might be cap plague, but I'm not sure. It looks more like glue TBH. Could someone help me figure out what might be wrong with this PC? EDIT: Sometimes, after these restarts, I noticed that the GPU fan doesn't spin up, and the single rear case fan that just happens to be connected to the same molex Y-cable as the GFX card doesn't spin up either. Anything to that? EDIT 2: I do use the system quite heavily, but I don't know how that will factor into this. I often play Diablo 3 and EVE Online at the same time, frequently alt-tabbing between the two. I also have Firefox open in the background, sometimes with several tabs, and if I feel like it, I'll mute the in-game sound and open foobar2000 for better music. Could it be that I'm just pushing this thing too hard? EDIT 3: I also noticed something odd. Right before I experience these restarts, my monitor would suffer from very faint lines of static moving across the screen. The monitor is still very much useable, but it is very annoying. Following the restart it disappears, and then would gradually re-appear over the next few days, and then restarts again. I find it to be very odd. System specs for good measure: Orion 600 W PSU AMD Athlon II X3 440 (overclocked to 3.14 ghZ, raised the CPU multiplier to x13 from x10) MSI G40-775 motherboard 1 GB inno3D GTX 550 ti 4 GB DDR3 RAM 500 GB Samsung SATA HD

• CPanel has two entries for site, need to use SSL one

  - by beingalex

  I have a website that is meant to be using SSL, however there are two entries in Cpanel's httpd.conf which seem to be causing an issue. When I visit just www.website.com I require it to go to https://www.website.com. However I have to write the https:// directly for the site to work. The secure site also has a different IP. I am not meant to edit the httpd.conf directly either and am unsure as to how to change the following directives: <VirtualHost 1.1.1.1:80> ServerName website.com ServerAlias www.website.com DocumentRoot /home/websitec/public_html ServerAdmin [email protected] ## User websitec # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup websitec websitec </IfModule> <IfModule !mod_disable_suexec.c> <IfModule !mod_ruid2.c> SuexecUserGroup websitec websitec </IfModule> </IfModule> <IfModule mod_ruid2.c> RUidGid websitec websitec </IfModule> CustomLog /usr/local/apache/domlogs/website.com-bytes_log "%{%s}t %I .\n%{%s}t %O ." CustomLog /usr/local/apache/domlogs/website.com combined ScriptAlias /cgi-bin/ /home/websitec/public_html/cgi-bin/ </VirtualHost> <VirtualHost 2.2.2.2:443> ServerName website.com ServerAlias www.website.com DocumentRoot /home/websitec/public_html ServerAdmin [email protected] UseCanonicalName Off CustomLog /usr/local/apache/domlogs/website.com combined CustomLog /usr/local/apache/domlogs/website.com-bytes_log "%{%s}t %I .\n%{%s}t %O ." ## User websitec # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup websitec websitec </IfModule> <IfModule !mod_disable_suexec.c> <IfModule !mod_ruid2.c> SuexecUserGroup websitec websitec </IfModule> </IfModule> <IfModule mod_ruid2.c> RUidGid websitec websitec </IfModule> ScriptAlias /cgi-bin/ /home/websitec/public_html/cgi-bin/ SSLEngine on SSLCertificateFile /etc/ssl/certs/www.website.com.crt SSLCertificateKeyFile /etc/ssl/private/www.website.com.key SSLCACertificateFile /etc/ssl/certs/www.website.com.cabundle CustomLog /usr/local/apache/domlogs/website.com-ssl_log combined SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown <Directory "/home/websitec/public_html/cgi-bin"> SSLOptions +StdEnvVars </Directory> # To customize this VirtualHost use an include file at the following location # Include "/usr/local/apache/conf/userdata/ssl/2/websitec/website.com/*.conf" </VirtualHost> As you can see there is obviously the unsecure directive before the secure one. And this is probably the issue, however if I try to change the IP for the site in WHM I get an error saying that the IP (2.2.2.2) is already in use. Which it is I guess. Any help is appreciated.
