  • Why is my biometric logon method no longer default and how to fix it? Win 7-based lenovo laptop

    - by StormRyder
    My laptop has been having some random problems with hibernating properly. That is a whole another topic that I still haven't resolved, but this is a different issue. The issues are connected, I guess, because one time after my computer experienced a failed hibernate, my login screen changed: since then my login screen always appears as the standard one with a prompt to type in a password. I can still use the finger scanner by clicking "other credentials" button. But that's annoying having to do that every time; previously the prompt to use finger scanner was the default one, whereas the typing password access was the alternate. How do I bring this arrangement back? In other words, how to switch the default from the type password prompt to the finger scan prompt? From online searches, I have only found discussions of turning the biometric access on or off... but clearly it is turned on and working, since I can use it. It's just not the default for some reason...

  • Windows, why 8 GB of RAM feel like a few MB?

    - by Desmond Hume
    I'm on Windows 7 x64 with 4-core Intel i7 and 8 GB of RAM, but lately it feels like my computer's "RAM" is located solely on the hard drive. Here is what the task manager shows: The total amount of memory used by the processes in the list is just about 1 GB. And what is happening on my computer for a few days now is that one program (Cataloger.exe) is continually processing large quantities of (rather big) files, repeatedly opening and reading them for the purposes of cataloging. But it doesn't grow too much in memory and stays about that size, about 90 MB. However, the amount of data it processes in, say, 30 minutes can be measured in gigabytes. So my guess was that Windows file caching has something to do with it. And after some research on the topic, I came across this program, called RamMap, that displays detailed info on a computer's RAM. Here is the screenshot: So to me it looks like Windows keeps in RAM huge amounts of data that is no longer needed, redirecting any RAM allocation requests to the pagefile on the hard drive. Even when I close Cataloger.exe, the RamMap reports the size of the mapped file as about the same for a long time on. And it's not just this particular program. Earlier I noticed that similar slowdown occurred after some massive file operations with other programs. So it's really not an exception. Whatever it is, it slows down the computer by like 50 times. Opening a new tab in Chrome takes 20-30 seconds, opening a new program can take up to a minute. Due to the slowdown, some programs even crash. So what do you think, is the problem hiding in file caching or somewhere else? How do I solve it?

  • APC fragmentation on EC2 Micro for Wordpress + W3TC

    - by Maarten Provo
    I'm trying to optimize APC for my Amazon EC2 Micro server running one Wordpress-site with W3TC. I've started with the settings advised by TechZilla in another topic but I keep getting high fragmentation with 50% of space being free. I've uploaded an image to http://www.maartenprovo.be/downloads/apc.jpg but I can't post it here since I need at least 10 reputation. What values can I optimize to prevent fragmentation? [apc] apc.enabled=1 apc.shm_segments=1 ;32M per WordPress install apc.shm_size=164M ;Leave at 2M or lower. WordPress does't have any file sizes close to 2M apc.max_file_size=2M ;Relative to the number of cached files apc.num_files_hint=1000 ;Relative to the size of WordPress apc.user_entries_hint=4096 ;The number of seconds a cache entry is allowed to idle in a slot before APC dumps the cache apc.ttl=7200 apc.user_ttl=7200 apc.gc_ttl=3600 ;Auto update chache files on change in WP-ADMIN or W3TC apc.stat=1 ;This MUST be 0, WP can have errors otherwise! apc.include_once_override=0 ;Only set to 1 while debugging apc.enable_cli=0 ;Allow 2 seconds after a file is created before it is cached to prevent users from seeing half-written/weird pages apc.file_update_protection=2 ;Ignore files apc.filters apc.slam_defense = 0 apc.write_lock = 1 apc.cache_by_default=1 apc.use_request_time=1 apc.mmap_file_mask=/var/tmp/apc.XXXXXX apc.stat_ctime=0 apc.canonicalize=1 apc.write_lock=1 apc.report_autofilter=0 apc.rfc1867=0 apc.rfc1867_prefix =upload_ apc.rfc1867_name=APC_UPLOAD_PROGRESS apc.rfc1867_freq=0 apc.rfc1867_ttl=3600 apc.lazy_classes=0 apc.lazy_functions=0

  • Issues with VPN functionality

    - by Xorandor
    I've been working on setting up VPN connectivity to our office location. We bought a Cisco WRV210 which have a builtin VPN server. Cisco has some software QuickVPN, which is not as quick and easy as I had thought. I've had mixed experiences on different machines with connecting. Instead I configured an IPSec VPN tunnel following a guide from TheGreenBow here http://www.thegreenbow.com/doc/tgbvpn_cg_linksys_wrv200_en.pdf I followed their instructions and tried out an evaluation of their software, and VPN connection should be working ok. I'm able to do RDP to a machine on the network (using IP address, not machine name) and ping the router etc. What I'm trying to solve are two things: It's not like I'm "really" on the network. Or at least I'm restricted to some degree when going through the VPN. I can't access a machine on the network using machine name, only IP. I can't ping a machine, but the router just fine. Could this be that something is not set up properly? If so, I can ofcourse supply additional information. Second, when I log onto the VPN, I would really like my outgoing connection to go through the internet connection of the remote location. Basically if I connect to the VPN I want my outgoing IP to be that of the remote location's (needed for some IP resctrictions on some of our servers). At a previous work location it worked like this when we connected to our office VPN over PPTP and the builtin windows VPN client. I'm not a huge expert on the topic, so any hints will be appreciated.

  • How to set up RAID-0 first time on new PC?

    - by jasondavis
    I have built basic PC's in the past but have never used a RAID array at all. SO now I am buying parts to build my new PC, it will be an intel i7 processor. My motherboard will have RAID support which I will use instead of an aftermarket raid controller for now. Also I plan to use 2 SSD drives in RAID-0 for my windows 7 OS. (Please note that I am aware of the issues with doing this, including lack of TRIM support when using RAID with SSD drives. I am OK with it not working as I can just re[place the drives in a year or so or wheneer they become more sluggish). SO here is my question part. If I assemble the motherboard, PSU, processor, RAM, vidm card, etc and then go to turn the PC on, it will have the 2 SSD drives hooked up. so I assume I will then soon the BIOS screen before I install windows? How to I go about making the 2 drives work in RAID-0 at this point? I do the raid part before installing my OS right? Please help with the steps involved from assembling the parts of the PC and then turning it on, to the part of getting the RAID-0 set up between the 2 drives and then installing my windows 7 OS from a Optical drive? Please help, all advice, instructions, tips appreciated as long as on topic. I do not need to be told that this is a bad idea as far as if 1 drive fails I losse it all, I plan on having a disk IMAGE to be able to restore my OS and software to a new set of drives at anytime needed in the event of drive failure. Same goes for lack of TRIM support. Thanks for reading and help =)

  • Good visuals supporting adopting Macintosh in a Windows company

    - by jdmuys
    I work in a Windows only software service company, which just put up an internal contest for innovative ideas for the company. The idea I submitted is to let employees use a Mac instead of the mandatory PC if they wished to. My idea has been selected (among a few others) to reach the next stage of the contest. One of the items requested for the next stage is ONE visual that best illustrates the idea. While my pitch is rather good (I think), I have a hard time coming up with ONE visual that would be suggestive enough and not too fanboy-ish, or too restricted. That's why I am requesting suggestions. For reference, some of the points I intend to develop are (not in order): de facto safety (little or no malware) Apple as a company reached its leading position through innovation (bio)diversity is a source of value for a service company, that expands its reach. it makes financial sense the Mac is the most compatible machine, making it a lot easier to test our software (especially web sites). Some OS X technologies can be valuable to a software service company (eg Applescript) Some Apple tools can help us improve (eg Keynote) It's good citizenship for our company as Apple is now best in class according to Greenpeace. I realize this question may be out of topic here. I'd be happy to have suggestions on where to post this question. Please do not argue why OS X might be better or worse than Windows. My question is very narrow. Thanks.

  • What's the piece of hardware listening on Facebook's or Wikipedia's IP address?

    - by Igor Ostrovsky
    I am trying to understand how massive sites like Facebook or Wikipedia work, for my intellectual curiosity. I read about various techniques for building scalable sites, but I am still puzzled about one particular detail. The part that confuses me is that ultimately, the DNS will map the entire domain to a single IP address, or a handful of IP addresses in the case of round-robin DNS. For example, wikipedia.org has only one type-A DNS record. So, people from all over the world visiting Wikipedia have to send a request to the one IP address specified in DNS. What is the piece of hardware that listens on the IP address for a massive site, and how can it possibly handle all the load coming from the requests for users all over the world? Edit 1: Thanks for all the responses! Anycast seems like a feasible answer... Does anyone know of a way to check whether a particular IP address is anycast-routed, so that I could verify that this really is the trick used in practice by large sites? Edit 2: After more reading on the topic, it appears that anycast is not typically used for dynamic web content. Anycast is usually used for UDP (e.g., DNS lookups), or sometimes for static content. One interesting thing to note is that Facebook uses profile.ak.fbcdn.net to host static content like style sheets and javascript libraries. Each time I ping this name, I get a response from a different IP address. However, I can't tell whether this is anycast in action, or a completely different technique. Back to my original question: as far as I can tell, even a large site will have a single expensive piece of load-balancing hardware listening on its handful of public IP addresses.

  • All my sites are 403 but the server is running. Errors on startup

    - by Craig
    We gave access to a contractor to install a firewall and somehow while he was doing it he fracked something up. Everything went off-line about 24 hours ago and we are effectively out of business until I solve this and the person who messed up the thing is not returning calls. I found a few errors. First, I'm not a server guy - I can look at log files and normally everything runs fine. All 'services' are running according to 1and1 server monitoring and mail is being delivered just fine. The whole thing was off-line until I (probably stupidly) updated the kernel from 6.2 to 6.3 this morning and I got everything back except the http access. All the domains (~200 of them) are returning a 403 error and nothing is recorded in the access log. On every restart I see this error in the messages log file: init: Failed to spawn ttyS0 main process: unable to execute: No such file or directory and a little later these: kernel: WARNING: at kernel/sched.c:5914 thread_return+0x232/0x79d() (Not tainted) kernel: Hardware name: X9SCL/X9SCM kernel: Modules linked in: xt_iprange iptable_filter ip_tables ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables ipv6 ext4 jbd2 serio_raw i2c_i801 i2c_core sg iTCO_wdt iTCO_vendor_support e1000e ext3 jbd mbcache raid1 sd_mod crc_t10dif ahci dm_mirror dm_region_hash dm_log dm_mod [last unloaded: scsi_wait_scan] kernel: Pid: 367, comm: md3_raid1 Not tainted 2.6.32-220.2.1.el6.x86_64 #1 kernel: Call Trace: kernel: [<ffffffff81069997>] ? warn_slowpath_common+0x87/0xc0 kernel: [<ffffffff810699ea>] ? warn_slowpath_null+0x1a/0x20 kernel: [<ffffffff814eccc5>] ? thread_return+0x232/0x79d kernel: [<ffffffff8126a4d9>] ? cpumask_next_and+0x29/0x50 kernel: [<ffffffff813e9c05>] ? md_super_wait+0x55/0x90 kernel: [<ffffffff81090a10>] ? autoremove_wake_function+0x0/0x40 kernel: [<ffffffff813ebf46>] ? md_update_sb+0x206/0x3f0 kernel: [<ffffffff813ee922>] ? md_check_recovery+0x3f2/0x6d0 kernel: [<ffffffffa005b129>] ? raid1d+0x49/0x1050 [raid1] kernel: [<ffffffff814ed985>] ? schedule_timeout+0x215/0x2e0 kernel: [<ffffffff814ef447>] ? _spin_unlock_irqrestore+0x17/0x20 kernel: [<ffffffff813eb336>] ? md_thread+0x116/0x150 kernel: [<ffffffff81090a10>] ? autoremove_wake_function+0x0/0x40 kernel: [<ffffffff813eb220>] ? md_thread+0x0/0x150 kernel: [<ffffffff810906a6>] ? kthread+0x96/0xa0 kernel: [<ffffffff8100c14a>] ? child_rip+0xa/0x20 kernel: [<ffffffff81090610>] ? kthread+0x0/0xa0 kernel: [<ffffffff8100c140>] ? child_rip+0x0/0x20 And something is wrong with the Named/BIND resulting in the same error for all domains: zone DOMAINEXAMPLE.com/IN: loading from master file DOMAINEXAMPLE.com failed: file not found zone DOMAINEXAMPLE.com/IN: not loaded due to errors. _default/DOMAINEXAMPLE.com/IN: file not found I'm pretty sure this is not enough information to solve the problem, but I'm willing to engage someone who can work this out for me. Any help would be greatly appreciated.

  • Is VGA port hot-pluggable?

    - by Martin Bøgelund
    In meetings, I often see people detaching the VGA connector from one running laptop and connecting it to another, while the projector is still on. Is this 100% risk free, and OK by design of the VGA standard? If there's a risk involved in hot-plugging VGA, can it be removed by turning off or suspending either laptop, display, or both? I see this being done all the time without causing disaster, so clearly I'm not interested in answers stating "we do it all the time, so it should be OK!". I want to know if there's a risk - real or in theory - that something breaks when doing this. EDIT: I did an internet search on the topic, and I never found a clear statement as to why it is safe or unsafe to hot swap VGA devices. The typical form is a forum question asking basically the same question as I did, and the following types of statements Yes it's hot swappable! I do it all the time! It involves some kind of risk, so don't do it! You're some kind of moron if you think there's a risk, so just do it! But no explanation as to why it safe or not... Joe Taylors answer below contains a link to a forum post and answers that basically give me the same statements as mentioned above. But again, no good explanation why. So I looked for an actual manual for a projector, and found "Lenovo C500 Projector User’s Guide". It states on page 3-1: Connecting devices Computers and video devices can be connected to the projector at the same time. Check the user’s manual of the connecting device to confirm that it has the appropriate output connector. [image] Attention: As a safety precaution, disconnect all power to the projector and devices before making connections. But again, no good explanation.

  • Relation between server_name in nginx sites-available, /etc/hosts file and A-records

    - by user2818584
    I have the following two server-blocks in my config-file in sites-available: server { listen 80; server_name www.mydomain.be; root /usr/share/nginx/html; index index.html index.htm; location / { try_files $uri $uri/ =404; } } server { listen 80; server_name sub.mydomain.be; root /usr/share/nginx/sub; index index.html index.htm; location / { try_files $uri $uri/ =404; } } I also created an A-record for both www.domain.be and sub.domain.be with the IP of my server as value. Yet, when I try to reload my nginx configuration with service nginx reload it fails. When I remove the second server-block, it reloads as expected. I know this topic is popular, and that there are loads of such [nginx][subdomain] questions here, but none of them seems to discuss explicitly how the following three things hang together: virtual hosts or server blocks in nginx (est. server_name matching) the effect of A-records on how nginx processes requests the need to add hosts to /etc/hosts Right now I have the impression that a lack of knowledge of this bigger picture, rather than specific knowledge of nginx configuration prevents me from making this work.

  • VPN Setup: Mac OS X and SonicWall

    - by noloader
    I'm trying to get VPN access up and running. The company has a SonicWall firewall/concentrator and I'm working on a Mac. I'm not sure of the SonicWall's hardware or software level. My MacBook Pro is OS X 10.8, x64, fully patched. The Mac Networking applet claims the remote server is not responding. The connection attempt subsequently fails: This is utter bullshit, as a Wireshark trace shows the Protected Mode negotiation, and then the fallback to Quick Mode: I have two questions (1) does Mac OS X VPN work in real life? (2) Are there any trustworthy (non-Apple) tools to test and diagnose the connection problem (Wireshark is a cannon and I have to interpret the results)? And a third question (off topic): what is broken in Cupertino such that so much broken software gets past their QA department? EDIT (12/14/2012): The network guy sent me "VPN Configuration Guide" (Equinox document SonicOS_Standard-6-EN). It seems an IPSec VPN now requires a Firewall Unique Identifier. Just to be sure, I revisited RFC 2409, where Main Mode, Aggressive Mode, and Quick Mode are discussed. I cannot find a reference to Firewall Unique Identifier. I think I am screwed here: I am trying to connect to a broken (non-standard) firewall, with a broken Mac OS X client. Fortunately, I can purchase VPN Tracker Personal (a {SonicWall|Equinox}-authored client) for $129US from Equinox. So much for standards....

  • Can't upgrade NVIDIA GeForce 310M display driver on Acer Aspire 5745PG

    - by Emerson
    I've been for days already trying to update my video driver. I have an Acer Aspire 5745PG with a "NVIDIA GeForce 310M" board, and I was trying to run Sony Vegas video editor with Boris Continunn plugins. It happened that some of the plugins, like BCC Text Extrude wouldn't work, showing the message "Insufficient depth resolution to run Blue". I then read somewhere that updating the display driver would do the trick. That was when my nightmares started, I lost already good 3 nights trying to sort this out, without success :( The display driver that was before (and that I current have after restoring) was the version 8.16.11.8997. First thing I tried was downloading the 8.17.12.6619 driver directly from Acer, which was shown as the latest version from Acer website: http://support.acer.com/product/default.aspx?modelId=2466 Running it would say "Diver Package Failure - Setup failed to read the required Display Driver to be used with this package" I then tried directly the NVIDIA own driver, which the latest was version 296.10: http://us.download.nvidia.com/Windows/296.10/296.10-notebook-win7-winvista-64bit-international-whql.exe That gave me similar error message :/ So after some researching I found out that some people had the same issue and they had to change the configuration file to allow the installer to recognize this NVIDIA board: http://forums.nvidia.com/index.php?showtopic=222904 That topic said to look for the "Device Instance Id" property of the "NVIDIA GeForce 310M" display , which I couldn't find, instead I found the "Hardware Id", which seemed to be the right one. I followed the instructions and changed the inf file first for the Acer installation, and after for the NVIDIA own driver. It actually managed to go ahead with the installation in both instances, but the only thing I got was a black screen, while the computer still apeared to be running fine. I had to hard reset, and then it would come back with generic vga driver. I could only get my display back using the recovery function. I imagine thousands of this notebook was sold, and it can't have its driver updated?? Could someone help me with this?? Thanks Echo

  • CLI package to replace Plesk

    - by dotancohen
    Myself and another programmer are tasked with maintaining a few webservers. I prefer CLI tools, she prefers Plesk. However, I am adamant about not installing Plesk for quite a few reasons. I have written a small Python script for adding new domains, and now I am about to add the ability to configure email addresses while abstracting the details of Postfix from her. Before I go that route, I have googled to see if anything already exists, and am surprised that I have come up with nothing! Are there any mature, stable "control panels" or "server admin" tools like Plesk, but which are accessed via the CLI over SSH? I am looking for the following features: Add / remove / configure domains served by Apache. Add / remove / configure email boxes and mail groups. Add / remove MySQL databases, users, and configure users to databases. Provide basic monitoring of "server health", that is: memory usage, disk usage, CPU usage, bandwidth usage. Possibly set up STFP accounts so that only specific FTP users could access specific /var/www/someSite/ directories. Note that I was unsure if this question is OT for ServerFault. As per the ServerFault about page (There seems to be no more FAQ) this question meets two of the "ask about" criterion and zero of the "don't ask about" with the possible exception of being opinion-based. Therefore, to keep on-topic, I would like to know about the available applications but we should be subjective and less opinionated. Thank you!

  • smartctl short test doesn't seem to complete

    - by Cédric COPY
    I am working on project which involve automated HDD testing through smartctl. The station is working fine on most product, but I have two specific products that fail the smartctl test. Those two product are both WD product (WD2500BUDT series) Smartctl behaviour is quite strange, in fact the test is launched without any problem, i wait about 2min (test length), and when i check the smartctl, i have got no result at all. It's like I hadn't launched any test (no fail, no success in smartctl result). No error return on command, nothing in syslog, .. As i said before, the test is working for other product, thousands products worked well with this test. The main smartctl command used are : smarctl -t shortest /dev/sdX #Launch test smartctl -l selftest /dev/sdX #Look at test result I have tried to use: smartctl -s on /dev/sdX or smartctl -o on /dev/sdX But doesn't change anything. The system is using Debian 6.0, smartctl v5.40 (rev 3124) x86_64, HDD are plug through SATA to PCI controller. I have 4 HDD connected at a time. Well if anyone has some hints to give with this problem, because I have no idea how can i fix this. Thanks in advance. PS: Not sure if it was a serverfault topic, sorry if i was wrong!

  • Production deployment to EC2 with minimal downtime

    - by jensendarren
    I have a simple web application deployed on a large instance with EC2. I now want to deploy the latest code to this server but I want to do this in a way which minimizes downtime and is a smooth as possible for the end user. Here is my plan: Fire up another large instance Install all the software layers on that instance Restore and attach an EBS drive to the instance Deploy our latest production ready code on the new instance Run all tests (including manual testing of the application) (If tests pass) Put a "Site Under Maintenance" notice on the live site. Backup the EBS instance on the live site Detach the EBS instance from the new server and replace with the latest backup Use ec2-associate-address to move the IP address to the new instance Sit back and wait for traffic to start flowing though the new instance Terminate the old instance Does this seem like a good strategy? Are there any tutorials or books that might cover this topic? I have already read Cloud Application Architectures by George Reese, which is an excellent book, but does not cover deployment. Additionally, I know that there are tools that can help with this like RightScale or enStratus which I will use when I start using more than one instance.

  • Require a very simple bash-based webserver for logging XML POST [on hold]

    - by Syffys
    As in title, it's for testing purpose and I need it to be extremely light (1 line to 1 single light file). Here is a XML query sample: XML_QUERY=$(cat <<EOF <?xml version='1.0' encoding='UTF-8'?> <Test></Test> EOF ) curl -H "Content-type: text/xml; charset=utf-8" -H "Soapaction: \"\"" -k -d "${XML_QUERY}" http://localhost:8088 Here are some of the tracks I have found so far even if I wasnt able to adapt them to work as I expect: Netcat minimal webserver: Problem is that my nc does not have the -q option, so the connection is closing before delivering the XML content Netcat Only webserver: Same as above Thanks in advance! EDIT: As it's been asked, I'm running Linux Redhat, even if the distro does not really matter and the OS implied since I'm asking a bash-based solution... Also about my topic being on hold: "Instead, describe your situation and the specific problem you're trying to solve" = I though this was exactly what I was doing, but ok I'll reword: My situation: bash environment (which can also include some standard linux tool: netcat, python or whatever) My specific problem: please see title: Require a very simple bash-based webserver for logging XML in HTTP POST for testing purpose

  • Tools for displaying a multidimensional data table?

    - by ShreevatsaR
    [Apologies if this sort of question is off-topic for SuperUser. Please redirect to the right place if so.] There is a 3-dimensional array of values. (That is, instead of a table/2-dimensional array with values in a grid, the values can be thought of in a cube instead.) Is there a way to display this "cube" interactively, ideally on a webpage? Specifically, given the data, it would work something like this: the user selects two of the 3 variables. He then sees a "stack" of tables, one for each value of the third variable (cross-sections, in other words). By selecting the appropriate table from the stack, he can see the (i,j,k) value he wants. The "technology" for displaying such a thing (stacked tables, rotation, etc.) already exists, so this seems the sort of thing that someone ought to have written already. To be clear: I don't need sophisticated graphics necessarily, just the ability to select from cross-sections of variables. But I have no experience with (say, for displaying on a webpage) what web gadgets exist, so I'm clueless how to even search for one. (Google searches like "multidimensional data visualization" didn't throw up anything useful. Google Spreadsheets can do a few kinds of charts which can be embedded on a webpage, but I cannot tell if this is one of them.) [I can imagine how it ought to work for higher dimensions. For four-dimensions, instead of selecting just a stack, you'd first select an (i,j) from an "outer table", which would show all (k,l) values for that (i,j). For higher dimensions, inductively: you select (i,j), and then repeat what you'd do with 2 fewer dimensions.] So has this been written? Is this easy to write? Where ought one to look for such a thing?

  • Errors generating gpg keypair

    - by Evan Lynch
    I posted this originally on stackoverflow, but was told that it was offtopic and this would be the better place to post it, so I am reposting it here and deleting my original topic. I have a rather old PGP key, but I've long ago lost the private key for it, so I'm trying to generate a new key with GPG on Windows 7. While it technically generates the key, GPA crashes every time I generate the keypair. I've tried this four times now and just downloaded what appears to be the latest version of Gpg4Win and am still receiving this problem. A comment on my original post informed me that GPA crashes is not a very good description of the problem, but unfortunately I can't do much better than that: all it tells me is "gpa.exe has crashed and will close now", I don't get an error dump or anything. Is there anything I can do to fix this, or is this just a bug in the latest version of Gpg4Win? Here are the specs of GPG that I'm using: GPA 0.9.4. GnuPG 2.0.22. My operating system is Windows 7 64 Bit, and I have 5 GB of RAM. Also, I was told to try generating the keypair on the command line but can't find any documentation for how to do this in Windows 7. If anyone could link me to current documentation for this, that would be a good workaround for solving this problem.

  • Apache sends plain-text response when accessing SSL-enabled site without HTTPS

    - by animuson
    I've never encountered something such as this before. I was attempting to simply redirect the page to the HTTPS version if it determined that HTTPS was off, but instead it's displaying an HTML page rather than actually redirecting; and even odder, it's displaying it as text/plain! The VirtualHost Declaration (Sort of): ServerAdmin [email protected] DocumentRoot "/path/to/files" ServerName example.com SSLEngine On SSLCertificateFile /etc/ssh/certify/example.com.crt SSLCertificateKeyFile /etc/ssh/certify/example.com.key SSLCertificateChainFile /etc/ssh/certify/sub.class1.server.ca.pem <Directory "/path/to/files/"> AllowOverride All Options +FollowSymLinks DirectoryIndex index.php Order allow,deny Allow from all </Directory> RewriteEngine On RewriteCond %{HTTPS} off RewriteRule .* https://example.com:6161 [R=301] The Page Output: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body> <h1>Moved Permanently</h1> <p>The document has moved <a href="https://example.com:6161">here</a>.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> I've tried moving the Rewrite stuff up above the SSL stuff hoping it'd do something and nothing happens. If I view the page with via HTTPS, it displays fine like it should. It's obviously detecting that I'm trying to rewrite the path, but it's not acting. The Apache error log does not indicate anything to me that might have gone wrong. When I remove the RewriteRules: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> Reason: You're speaking plain HTTP to an SSL-enabled server port.<br /> Instead use the HTTPS scheme to access this URL, please.<br /> <blockquote>Hint: <a href="https://example.com/"><b>https://example.com/</b></a></blockquote></p> <p>Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> I get the standard "you can't do this because you're not using SSL" response, which is also provided in text/plain rather than being rendered as HTML. This would make sense, it should only work for HTTPS-enabled connections, but I still want to redirect them to the HTTPS connection when it determines that it is not enabled. Thinking I could circumvent the system: I tried adding a ErrorDocument 400 https://example.com:6161 to the config file instead of using RewriteRules, and that just gave me a new message, still no cheese. <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>302 Found</title> </head><body> <h1>Found</h1> <p>The document has moved <a href="https://example.com:6161">here</a>.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> How can I force Apache to actually redirect rather than displaying a "301" page that shows HTML in plain-text format?

  • How does Windows 7 taskbar "color hot-tracking" feature calculate the colour to use?

    - by theyetiman
    This has intrigued me for quite some time. Does anyone know the algorithm Windows 7 Aero uses to determine the colour to use as the hot-tracking hover highlight on taskbar buttons for currently-running apps? It is definitely based on the icon of the app, but I can't see a specific pattern of where it's getting the colour value from. It doesn't seem to be any of the following: An average colour value from the entire icon, otherwise you would get brown all the time with multi-coloured icons like Chrome. The colour used the most in the image, otherwise you'd get yellow for the SQL Server Management Studio icon (6th from left). Also, the Chrome icon used red, green and yellow in equal measure. A colour located at certain pixel coordinates within the icon, because Chrome is red -indicating the top of the icon - and Notepad++ (2nd from right) is green - indicating the bottom of the icon. I asked this question on ux.stackoverflow.com and it got closed as off-topic, but someone answered with the following: As described by Raymond Chen in this MSDN blog article: Some people ask how it's done. It's really nothing special. The code just looks for the predominant color in the icon. (And, since visual designers are sticklers for this sort of thing, black, white, and shades of gray are not considered "colors" for the purpose of this calculation.) However I wasn't really satisfied with that answer because it doesn't explain how the "predominant" colour is calculated. Surely on the SQL Management Studio icon, the predominant colour, to my eyes at least, is yellow. Yet the highlight is green. I want to know, specifically, what the algorithm is.

  • Cannot connect to website - SSL handshaking fails

    - by ravenspoint
    So I cannot connect to certain websites. Just a few, most are OK. The one I really care about is paypal.com. I have done the usual things. Let's see: Checked my etc/hosts Flushed the DNS cache Checked firewall Switched on & off virus protection Switched on and off ad blocking pinged the sites Eventually, I decided to look at what curl is saying in detail == Info: About to connect() to www.paypal.com port 443 (#0) == Info: Trying 66.211.169.2... == Info: connected == Info: SSLv3, TLS handshake, Client hello (1): => Send SSL data, 110 bytes (0x6e) 0000: 01 00 00 6a 03 01 4f 6c aa 8c 57 2b 3d 1e 74 64 ...j..Ol..W+=.td 0010: c1 27 25 a5 3a 12 7f 3f 41 0a 17 15 2e c9 67 7c .'%.:.?A.....g| 0020: b3 e1 f6 9a db a9 00 00 2a 00 39 00 38 00 35 00 ........*.9.8.5. 0030: 16 00 13 00 0a 00 33 00 32 00 2f 00 07 00 05 00 ......3.2./..... 0040: 04 00 15 00 12 00 09 00 14 00 11 00 08 00 06 00 ................ 0050: 03 00 ff 01 00 00 17 00 00 00 13 00 11 00 00 0e ................ 0060: 77 77 77 2e 70 61 79 70 61 6c 2e 63 6f 6d www.paypal.com (hangs here for ever) This looks to me like paypal is refusing to reply to the first SSL handshake. I don't know much about SSL, but compaing to the output from a site that works for me seems to make it obvious == Info: About to connect() to www.cibc.com port 443 (#0) == Info: Trying 159.231.80.200... == Info: connected == Info: SSLv3, TLS handshake, Client hello (1): => Send SSL data, 108 bytes (0x6c) 0000: 01 00 00 68 03 01 4f 6c ad 6a 1f 67 d5 84 c4 4b ...h..Ol.j.g...K 0010: 0d 49 ae d6 b9 5b c3 63 f9 48 aa 18 da 43 d1 32 .I...[.c.H...C.2 0020: 47 ae 17 e5 cd e9 00 00 2a 00 39 00 38 00 35 00 G.......*.9.8.5. 0030: 16 00 13 00 0a 00 33 00 32 00 2f 00 07 00 05 00 ......3.2./..... 0040: 04 00 15 00 12 00 09 00 14 00 11 00 08 00 06 00 ................ 0050: 03 00 ff 01 00 00 15 00 00 00 11 00 0f 00 00 0c ................ 0060: 77 77 77 2e 63 69 62 63 2e 63 6f 6d www.cibc.com == Info: SSLv3, TLS handshake, Server hello (2): <= Recv SSL data, 74 bytes (0x4a) 0000: 02 00 00 46 03 01 00 00 58 cf 26 e2 e1 65 db 11 ...F....X.&..e.. 0010: bc 6f 26 7b 3b 6d eb 14 5f ad 47 dd 86 ea 4d a3 .o&{;m.._.G...M. 0020: fb 9f b7 2a 54 3e 20 5f 6b 04 5a 12 38 64 5d 18 ...*T> _k.Z.8d]. 0030: 65 9e e9 cd 61 eb 91 c1 16 25 61 30 bb 08 2a 78 e...a....%a0..*x 0040: b8 ee b8 7e f2 65 6a 00 04 00 ...~.ej... == Info: SSLv3, TLS handshake, CERT (11): ... and so on - working nicely eventually get some nice HTML Now I am reaaly stuck. This has been going on for five days, so I am pretty sure that the problem is not with paypal. But what on my system could be interfering with the SSL handshaking done by curl with this particular site? I suppose I could not be offering any certificates that PayPal accepts, but wouldn't I get a reply telling me so, or at least giving an error?

  • Barriers to IPv6 deployment: addressing

    - by sysadmin1138
    There are several things that are keeping IPv6 deployment from being a topic of active discussion here at my work. There are the usual technical issues, but one non-technical one appears to be a major stumbling block on the path to actually getting a deployment project going. Addresses, memorizing of. Specifically, IPv4 addresses are comprehensible, and IPv6 addresses just look like a big long string of hex. The human mind has real trouble memorizing lists of more than 7-8 items, and an IPv4 address (192.168.231.148) has four items in it which makes it easy for us to memorize. A fully populated IPv6 address has not only 8 sections, but each section has 4 hex digits in it. IPv6 addresses were not designed for memorization. To the technician who knows that the DNS server is at 192.168.42.42 (or more likely "42.42", since the company prefix is likely memorized), the idea of memorizing an IPv6 address fills them with dread. Which in turn makes them much less enthusiastic about participating in an IPv6 deployment project. Because of how our network works we're not fully dynamic in terms of v4 addressing. We have several to many subnets that are entirely statically assigned for a variety of reasons, chief among them being that the overhead of static DHCP assignments is perceived as being too great. Also, some devices still aren't smart enough to pull DNS addresses out of DHCP while also having a static assignment, and therefore require manually configured DNS settings. Therefore, some v6 address memorization will have to be done. We're not under any mandate to get v6 out the door, so we don't have pressure from the top. However, it is time to start prepping our infrastructure to handle IPv6 even if we don't convert wholesale. For those of you who have been in IPv6-land for a while, what short-cut methods do you use to discuss or keep track of subnets and specific/critical IP addresses? If I can help reduce some of the dread surrounding IPv6 we might get the project going.

  • What are these isolated resource requests in Apache's access_log?

    - by Greg
    I was looking at my Apache access log and came across some strange requests. A single IP address will access several resources (mostly css style sheets and images), but no actual pages. Sometimes they are requesting a resource that no longer exists on the server, or one that is still under the web root but no longer used (e.g. a resource in an old WordPress theme). Also: The requests list no referrer I get no useful information on the IP address by looking it up There doesn't seem to be any pattern among the IP addresses that are making these requests (e.g. different countries) Are these just links from a stale cache somewhere? Could it be a sign of an attack of some sort? Here is a typical example: GET /wp-content/themes/my-theme/images/old-image.gif HTTP/1.1" 500 809 "-" "Mozilla/4.0 (compatible;)" This was one of about 10 similar requests, some for existing resources, some for older resources. There is no other sign of this IP address in access_log. Note the internal server error, which is a topic for a different thread. What I'm asking here is where would isolated requests like this come from?
