  • How do I configure Jetty (via jettyrunner) so that it names a character set in the Content-Type response header?

    - by Pointy
    I use Jetty (via the oh-so-handy Jetty Runner) for day-to-day web application testing. One thing I've recently stumbled on is the fact that I don't get a character set called out in the "Content-Type" response header all the time. I do get it in response to my application's XMLHttpRequest transactions, but not for plain old pages loaded by <a> links or whatever. I've read a little bit about how to set up a Jetty config file, but I've never been able to completely understand that; all servlet containers are complicated, and while Jetty is pretty simple it's just weird enough that I don't grok the overall idea. Thus, all I do to launch my app is to run the Jetty Runner .jar file with a couple of simple arguments to set up the port number and logfile path, and then I just give it the .war file to run. It works great — except for the missing character set :-) Anybody have a quick sample config file that might fix this? edit — oh if it matters, I'm running Jetty 7.0.0 RC3; I've also tried with a slightly newer version (still 7.something) with exactly the same issue. All my testing is on Ubuntu.

  • How to setup apache to catch a proxy_pass from nginx?

    - by Paté
    I have a working apache vhost such as <VirtualHost localhost:10006> DocumentRoot "/home/pate/***/git/kohana_site/public/site/" </VirtualHost> <VirtualHost *:10006> ServerName api.* DocumentRoot "/home/pate/***/git/kohana_site/public/api/" LogLevel debug </VirtualHost> If i point to localhost:10006 I get my website and api.localhost:10006 I get my api. Then I have haproxy setup on top of that, that runs on port 10010 and both localhost:10010 and api.localhost:10010 have the expected behaviour. Now I have nginx setup on port 80 with this configuration. server { listen 10000; server_name api.*; location / { proxy_pass http://legacy_server; } } server { listen 10000 default; server_name _; location /nginx_status { stub_status on; access_log off; } # images are accessed via the CDN over HTTP (not https) location /n/image { proxy_pass http://image_caching_server; } location / { return 301 https://$host:10014$request_uri; } } upstream legacy_server { server localhost:10010 fail_timeout=0; } the problem is that apache does not recognize the vhost properly and redirects api.localhost to the website instead of the api. I tried playing with set_proxy_header Host $host but it doesn't seem to do anything.

  • Compare-Object gives false differences

    - by Andy
    I have some problem with Compare-Object. My task is to get difference between two directory snapshots made at different times. First snapshot is taken like this: ls -recurse d:\dir | export-clixml dir-20100129.xml Then, later, I get second snapshot and load both of them: $b = (import-clixml dir-20100130.xml) $a = (import-clixml dir-20100129.xml) Next, I'm trying to compare with Compare-Object, like that: diff $a $b What I get is in some places files that were added to $b since $a, but in some -- files that were in both snapshots, and some files, that were added to $b, are not given in Compare-Object output. Puzzling, but $b.count - $a.count is EXACTLY the same as (diff $a $b).count. Why is that? Ok, Compare-Object has -property param. I try to use that: diff -property fullname $a $b And I get the whole mess of differences: it shows me ALL the files. For example, say $a contains: A\1.txt A\2.txt A\3.txt And $b contains: X\2.mp3 X\3.mp3 X\4.mp3 A\1.txt A\2.txt A\3.txt diff output is something like that: X\2.mp3 => A\1.txt <= X\3.mp3 => A\2.txt <= X\4.mp3 => A\3.txt <= A\1.txt => A\2.txt => A\3.txt => Weird. I think I don't understand something crucial about Compare- Object usage, and manuals are scarce... Please, help me to get the DIFFERENCE between two directory snapshots. Thanks in advance UPDATE: I've saved data as plain strings like that: > import-clixml dir-20100129.xml | % { $_.fullname } | out-file -enc utf8 a.txt And results are the same. Here're excerpts of both snapshots (top 100-something lines, a.txt and b.txt), output of compare-object, and output of UNIX diff (unified). All files are UTF-8: http://dl.dropbox.com/u/2873752/compare-object-problem.zip

  • Is it possible to get ESC to behave as an actual escape key?

    - by leftaroundabout
    So I have finally switched, not so much because I'm yet convinced Emacs in itself is the better editor but because it certainly does have more powerful extensions. I am still using vim-mode though, perhaps that's part of my problem... but I really don't intend to abandon the modes-approach, so I'll probably stay with it. I'm getting along quite well, but one thing I find really unnerving is the behaviour of the esc key (which I have in the shift-lock position). I'm used to relying on this a lot as more or less a "panic key", which may not be nice but I find allows me to work generally quite a bit less caring about the keystrokes themselves, and thus faster. What I'd like this key to do is just get me out of any minibuffer or special editing mode into a well-defined normal state. Perhaps most importantly, I would like it to not do anything unrelated, Simulate meta. What do I have an alt key for? Close windows I'm not even in at the time. Getting interpreted as the final key in some key sequence. ... Is it possible to turn all that off and make esc an actual escape key? Vim-mode does make it behave kind of as I like in some situations, but when other plugins are involves this often breaks. Alternatively, are there different options that might suit my kind of workflow?

  • Bridging networks problems

    - by Eric
    In my setup I have 3 computers and 2 (wireless d-link) routers. Computer1 has ethernet and wireless interfaces ethernet : 192.168.0.x (DHCP) wireless : 192.168.10.254 (static) Computer 2 has ethernet with two ips ethernet1 : 192.168.0.90 (static) ethernet2 : 192.168.10.110 (static) Computer 3 is a particular device with a hardcoded ip that I can't change wireless : 192.168.10.41 (static) Router1 manages internet and DHCP for network 192.168.0.0/24 Router2 is more complicated. I don't use DHCP. I use it to bridge between both networks. Its static ip is 192.168.10.1 Computer1 can ping Computer2. Computer1 can ping Computer3. Computer1 can ping Router1. Computer1 cannot ping Router2. Computer2 cannot ping Computer3. Computer2 can ping Router2. Router1 can ping Router1 Router2 can ping Computer2 Router2 cannot ping Computer1 Router2 cannot ping Computer3 This is very weird. Router2 manages the wireless connection, it should be able to ping its own computers right? My question is obviously : How can I make it so Computer2 can access everything else. This is a traditional case of "it was working before christmas and now it doesn't". The ethernet wiring is as follow : [ Computer1 ]----[ Router1 ]---[ Router2 ]---[ Computer3 ] I am using switch (lan) ports on Router1/2.

  • Manual Http error response code in non-existent folder via routing

    - by Slytherin
    Apache server running on ubuntu-like linux I am getting unexpected behaviour when i try to manually send error response. If my .htaccess is responsible for the error response , then appropriate error document is loaded and displayed , with according response code in browser console. However , if my router is origin of the response code , then i get blank screen , but correct response code. .htaccess looks like this RewriteEngine On # RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule !\.(css|js|icon|zip|rar|png|jpg|gif|pdf)$ index.php [L] ErrorDocument 404 /err/404.html ErrorDocument 403 /err/403.html ErrorDocument 500 /err/500.html part of my router that sends the response is the following header("HTTP/1.1 403 Forbidden"); trying this format didnt help either header("HTTP/1.1 403 Forbidden", TRUE, 403); I also tried HTTP/1.0. Furthermore i was thinking that maybe relative path to error page might be an issue , but discarded this idea after attempting to access a document that is forbidden via .htaccess EDIT I should also point out , this scenario happens when URL for not-existing article is requested. Is it possible that Server is looking for a .htaccess file in a folder based on URL ? Eg: domain/blog/non-existent , is server looking for blog folder ? I am specifically asking this because there is no blog folder

  • Restore a database with LDF file only

    - by Martin
    First of all, i know how stupid it is not to have a any backup. I can't help it, but i have to (try) to solve it. I have a transaction log (LDF) file from a SQL Server 2000 database that contains all transactions since the creation of the database. No truncation has been done. The MDF file is gone. Probably because of some disk failure. There is no backup. Not from the original database and not from the transaction log. I have tried to link the transaction log to a new clean database. But (ofcourse) that failed because SQL Server checks the identity of both files. I have read about software that can read the transaction log. ApexSQL seems to do that. I tried to install the trial version but it gives weird errors when trying to start the program. Anyone knows a solution for me? It may contain third party software, but i prefer a clean SQL Server solution.

  • InstallShield or Windows installer corrupted

    - by Bobby S
    Just recently I've been unable to install any software on my Windows 7 machine. Anything that uses InstallShield or the Windows installer will just hang or give a weird error. I noticed there will be many duplicate isbew64.exe processes (like 25) that launch and then just sit there or else a lot of msiexec.exe *32 processes, depending on what I'm trying to install. One piece of software specifically is the Logitech Harmony software. It gives me an *is_string_not_defined* error, saying c:\program files (x86)\:\ the filename, directory name, or volume label syntax is incorrect. The other thing I was trying to install was Battlefield: Bad Company 2, and that just hangs as well, and then just leaves all the Windows installer processes running in the background after I quit the install process. Very odd. I've checked well and googled these issues, it doesn't appear to be any sort of malware issue. I feel like it's related to some kind of corrupted installer application. I've rebooted, deleted the InstallShield folder in program files/common files as some places online suggested but to no avail. I have no idea what to do, any ideas?

  • Permissions error when creating desktop shortcut

    - by Ryan M.
    Hey guys, I have a user that's got a weird permissions problem on Windows 7. He's trying to create a shortcut for Outlook on his desktop(he doesn't want it in his start menu or his taskbar...). If we right click the outlook.exe and do Send to Desktop, it works just fine. If we do a search for "outlook" in the search bar, and then try and drag and drop the outlook icon to the desktop, we get the error message "You need Permission to perform this action. You require permission from SYSTEM to make changes to this file: Microsoft Office Outlook 2007". Dragging and dropping other exe's onto the desktop work just fine. They create shortcuts without any problems. But if I try to do ANY of the Office programs (Word, Excel, Outlook, etc..) I get this permission error. Any ideas? He's using an A.D. account and he's in the local administrators group. He's an executive so he's not accepting "this isn't a real problem because I found another way to make a shortcut" as an answer. Any help is appreciated.

  • SSH hangs when executing command remotely

    - by Serty Oan
    Client : OpenSSH_5.1p1 Debian-5ubuntu1 (Ubuntu 9.04) Server : OpenSSH_5.1p1 Debian-5 (Proxmox 2.6.24-7-pve) I use SSH to execute commands remotely on the server (module check_by_ssh of Nagios). But SSH hangs from time to time when trying to execute commands. I can log to the server via SSH but not executing a simple 'ls'. And it seems to block from all clients from the same IP address. Authentication is not the problem, may it be made by SSH keys or password. ssh -l root -p 2222 server.domain.tld 'ls' Here the client debug info debug1: Entering interactive session. debug2: callback start debug2: client_session2_setup: id 0 debug1: Sending environment. debug3: Ignored env ORBIT_SOCKETDIR *** skipping approx 40 env var ignored debug1: Sending command: ls debug2: channel 0: request exec confirm 1 It hangs there. Then after a random time, it works again (without doing anything). Killing all sshd process on the server seems to work too. It works from a Putty. I saw that some people had trouble like this due to ISP reverse DNS problem, but it does not seem to be the case here. It can work for hours and then not work for half an hour or so. What could explain this behaviour ?

  • SQL Server 2008 services error on account

    - by TheDude
    I installed SQL Server Enterprise, but can't get it to work. It is a stand alone, on a laptop for development purposes. No network is involved, no other users. The OS is windows 7. Now, I keep receiving eventId 7000, which means that access is denied for the user (the user was Network Services). So, after reading up on it, I kind of got the idea that a user account should be created with minimal privileges. So, off I went and added a user, SQLservices. In the SQL Server Configuration Manager I right clicked SQL Server(MSSQLSERVER), and in the properties I added my new user. Well, here's mister eventId 7000 again. I don't get what I am doing wrong. Also, this new user ends up on my start-up screen. I don't think I want that... I mean, it would be weird to have x number of users crowding up my start-up screen just because I created those for my windows services... The error I get when I add the user in SQL Server Configuration Manager is as follows: Permission Denied. [0x80070005] Helps!

  • Adventures in Drupal multisite config with mod_rewrite and clean urls

    - by moexu
    The university where I work is planning to offer Drupal hosting to staff/faculty who want a Drupal site. We've set up Drupal multisite with clean urls and it's mostly working except for some weird redirects. If you have two sites where one is a substring of the other then you'll randomly be redirected to the other site. I tracked the problem to how mod_rewrite does path matching, so with a config file like this: RewriteCond %{REQUEST_URI} ^/drupal RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /drupal/index.php?q=$1 [last,qsappend] RewriteCond %{REQUEST_URI} ^/drupaltest RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /drupaltest/index.php?q=$1 [last,qsappend] /drupaltest will match the /drupal line and all of the links on the /drupaltest page will be rewritten to point to /drupal. If you put the end of string character ($) at the end of each rewrite condition then it will always match on the correct site and the links will always be rewritten correctly. That breaks down as soon as a user logs in though because the query string is appended to the url so just the base url will no longer match. You can also fix the problem by ordering the sites in the config file so that the smallest substring will always be last. I suggested storing all of the sites in a table and then querying, sorting, and rewriting the config file every time a Drupal site is requested so that we could guarantee the order. The system administrator thought that was kludgy and didn't address the root problem. Disabling clean urls should also fix the problem but the users really want them so I'd prefer to keep them if possible. I think we could also fix it by using an .htaccess file in each site to handle the clean url rewriting but that also seems suboptimal since it will generate a higher load on the server and the server is intended to host the majority of the university's external facing web content. Is there some magic I can do with mod_rewrite to get it to work? Would another solution be better? Am I doing something the wrong way to begin with?

  • MSMQ on Win2008 R2 won't receive messages from older clients

    - by Graffen
    I'm battling a really weird problem here. I have a Windows 2008 R2 server with Message Queueing installed. On another machine, running Windows 2003 is a service that is set up to send messages to a public queue on the 2008 server. However, messages never show up on the server. I've written a small console app that just sends a "Hello World" message to a test queue on the 2008 machine. Running this app on XP or 2003 results in absolutely nothing. However, when I try running the app on my Windows 7 machine, a message is delivered just fine. I've been through all sorts of security settings, disabled firewalls on all machines etc. The event log shows nothing of interest, and no exceptions are being thrown on the clients. Running a packet sniffer (WireShark) on the server reveals only a little. When trying to send a message from XP or 2003 I only see an ICMP error "Port Unreachable" on port 3527 (which I gather is an MQPing packet?). After that, silence. Wireshark shows a nice little stream of packets when I try from my Win7 client (as expected - messages get delivered just fine from Win7). I've enabled MSMQ End2End logging on the server, but only entries from the messages sent from my Win7 machine are appearing in the log. So somehow it seems that messages are being dropped silently somewhere along the route from XP or 2003 to my 2008 server. Does anyone have any clues as to what might be causing this mysterious behaviour? -- Jesper

  • Diff bios - corrupt video driver

    - by sfonck
    Hi, I'm using an Dell M90 Precision Laptop which has a NVidia Quadro FX 2500M graphics card and is running Windows XP. Laptop has been running fine - but a few weeks ago screen went 'white' - restarted computer- bios and startup screens show weird green dots and stripes, normal startup only shows a black screen... only VGA mode works to display something. I've been trying to remove and reinstall the correct drivers downloaded from Dell's website - no solution. I gave up and reinstalled XP - everything was working perfect again. 2 weeks later - again the white screen - tried everything again (flashin new bios also - nothing works) Reinstalled XP - everyhting was working again, so I made a DriveSnapShot of the partition. Today - again the 'white screen'. Ok, no problem ...I was thinking all I needed to do was to restore the DriveSnapShot backup... Few minutes later the backup is restored ... but guess what: video driver does not work correctly... As the DriveSnapShot restored the complete partition, as it was at the time everything was working perfectly, this would mean my driver problems are due to 'settings' in the bios or on the graphics-card itself + these 'settings' can get overridden by doing a new XP-install.... I'm out of options, can somebody help me to find a solution for this problem: Is there some way to backup and restore a bios after seeing some problems? Is there some way to know what is causing this problem like a bios diff utility? Thanks!

  • Hiding my location to websites with region-specific languages/content

    - by Tudor
    I just went to download Microsoft Secority Essentials and it enraged me as it redirected me to a site in my home language and not the default English. If I go to America, I don't want them to speak Swahili. It reminded me of all the other websites who try to do the same. I don't want my content in greek when I'm on vacation! I for one simply can't work on a computer unless the language is English (or unless there's a VERY good reason to change the language). Location aware content is only good for download mirrors, and even then I would rather pick from a list of countries myself. (or if you can't speak anything but your own language) I know websites get your location from your IP and ISP, but is there any way you can inhibit this behaviour on a browser level? Is there any Chrome/Firefox extension for it? Do I really have no choice but to hide my IP? There's all sorts of services that claim they're hiding your IP for free so that people can't log and trace your steps through the internet, but they're probably logging it themselves and making money off it. Why else would they be free? I've found that Firefox has an Option that says "Choose your preferred language when displaying pages". Haven't found anything for Chrome.

  • Truecrypt files corrupted after moving PC into another case

    - by Dygerati
    I recently bought a new PC case and transferred all of my PC hardware into it. The only hardware modification was the addition of two identical ram modules. The entire process went smoothly, and everything worked and booted as before. The only side-effect I found when accessing one my of file-based hidden truecrypt volumes shortly there after. Some of the files in the volume - NOT all - seemed to be entirely corrupted. The directory and file names are garbled characters, but a few of the directories in the same volume appear and function normally. Also, all files in the non-hidden tc volume were still intact. Is this not weird? The only other real change I could think of would be that the hard drives were connected to different SATA ports on the mobo. I really don't know how the truecrypt encryption works well enough to know what could cause this...and the fact that not all the files were corrupted makes it more bizarre still. So, first off (and I'm not too hopeful on this point), would it be possible to restore these files? I had a backup of most, but not all of the files involved. Other than that I'm just curious how this happened and how I can prevent it next time. Thanks!

  • Is it possible to command a common router without using the web interface?

    - by MDeSchaepmeester
    Some background The internet arrangement in my student home is really weird. There is one ethernet outlet and several wifi hotspots. Either way requires a login through a web site to get internet access. This is annoying as each device needs to login seperately and with a PS3 for example, it is impossible to get connected at all since the web login procedure doesn't work. Therefore I have installed a D-Link DIR-635 router which is connected to the ethernet outlet. It has DHCP enabled so it uses NAT, but whatever it is connected to also uses NAT and I've read this should not work. A fellow student tried it with an Apple Airport but that keeps giving errors related to NAT after NAT. Anyway my setup does work so bonus points if you can clarify this. I need to login to the web site I mentioned earlier with any device, after which all devices in my LAN have connectivity. This is great. Except... In short From time to time, I lose internet connectivity and my D-Link DIR-635 router needs to do a DHCP renew. I can do this via the web interface but my life would be easier if I could just run a cmd file which tells my router to do this without all the hassle. This would setup a connection to my router and execute the proper command. I have tried googling but couldn't find much helpful stuff.

  • Cisco AnyConnect VPN client - prevent connecting as work network

    - by Opmet
    From Windows 7 I'm using "Cisco AnyConnect Secure Mobility Client 3.0" to connect to our corporate network. Every time I establish the VPN connection Windows will set the type as "work network". I don't want this. So I go to "network and sharing center" and manually / interactively change it to "public network". But I have to repeat it for every new VPN connection. Is there any way to make Windows remember / persist this configuration? Can it be configured in the VPN client? Do our IT admins need to change something at server end? Motivation: A "work network" per default uses different firewall settings that allows for stuff like "network discovery" and "file shares". But I just need "remote desktop" (mstsc). Additional info: Our IT admins claimed this would be Windows default behaviour and there was nothing we could do about it: Windows would always initiate a VPN connection as "work network". Based on this statement I assume this is a "general" issue and went ahead posting here (at superuser.com).

  • Nginx conditional not evaluating correctly

    - by cjc
    I'm running into a weird problem with nginx and how it evaluates conditionals. Here's the relevant configuration: set $cors FALSE; if ($http_origin ~* (http://example.com|http://dev.example.com:8000|http://dev2.example.com)) { set $cors TRUE; } if ($request_method = 'OPTIONS') { set $cors $cors$request_method; } if ($cors = 'TRUE') { add_header 'Access-Test' "$cors"; add_header 'Access-Control-Allow-Origin' "$http_origin"; add_header 'Access-Control-Allow-Methods' 'POST, OPTIONS'; add_header 'Access-Control-Max-Age' '1728000'; } if ($cors = 'TRUEOPTIONS') { add_header 'Access-Test' "$cors"; add_header 'Access-Control-Allow-Origin' "$http_origin"; add_header 'Access-Control-Allow-Methods' 'POST, OPTIONS'; add_header 'Access-Control-Allow-Headers' 'X-Requested-With, X-Prototype-Version'; add_header 'Access-Control-Max-Age' '1728000'; add_header 'Content-Type' 'text/plain'; } So, the conditional blocks never trigger. When I remove the conditions, I see that the "Access-Test" header and the "Access-Control-Allow-Origin" set correctly, but, as noted, enabling the conditionals causes the headers not to be sent. I'm testing by running: curl -Iv -i --request "OPTIONS" -H "Origin: http://example.com" http://staging.example.com/ Am I missing something obvious? I've tried the "if" with and without quotes, etc. This is nginx 1.2.9.

  • Is it logical that file system acls would be corrupted in a way that adds permission for another user?

    - by wilbbe01
    I was having issues on a shared hosting provider with the host's web server instance not serving some files. I asked the companies support about the issue and they responded with the results of getfacl on my home directory, and added the necessary line to allow their web server to obtain the necessary permissions. All is working happily now, but I noticed a line in the getfacl that was for what appeared to be another username to which I had no relation. I asked them about this and their response was that it was likely some minor corruption and that I could remove the unwanted line with the setfacl -x option. I know I never added the user to my home directory, and I also find it weird that that could truly happen due to corruption. So now that it is fixed I'm a little bit weary of whether or not they were trying to cover up a problem they accidentally gave someone permissions to my account, or if this kind of thing can really be corrupted in that way. Especially when that user is a real user on the same server. Any thoughts? Thanks.

  • What is the --daemon option?

    - by Pascal Dimassimo
    I was installing Solr with Jetty using these instructions. Basically, those instructions made you download the Jetty startup script and copy it to /etc/init.d/jetty. But it was not working. Each time I was starting Jetty, I had a "FAILED" message and nothing to understand why it was happening. I decided to open up the /etc/init.d/jetty script to understand what was happening. I saw that this script was using start-stop-daemon to launch jetty. After a couple of time of debugging, I discovered that removing the --daemon option at the end of the start-stop-daemon call was fixing my problem. I did a couple of research and discovered that this guy had the same problem and resolved it like I did: my removing the --daemon option. What is weird is that the switch does not seem to be specific to start-stop-daemon, because it is not documented in the man page. Also, I've seen it used for other commands. So what is that --daemon option doing? And why removing it resolved my problem? Note that I am working on Ubuntu 10.04.2 LTS.

  • Mysterious swap usage on EC2

    - by rusty
    We're in the middle of a project to move our infrastructure from a co-lo situation into Amazon EC2 and we've noticed some weird memory characteristics of the processes in our setup. Without going into too much detail about the specifics of our processes, we've noticed that on our EC2 instances "top" will show processes using a lot of swap space -- in fact, much greater than the amount of available swap or (if you add it all up) more than the available disk. Here's a sample top output: Mem: 7136868k total, 5272300k used, 1864568k free, 256876k buffers Swap: 1048572k total, 0k used, 1048572k free, 2526504k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP COMMAND 4121 jboss 20 0 5913m 603m 14m S 0.7 8.7 3:59.90 5.2g java 22730 root 20 0 2394m 4012 1976 S 2.0 0.1 4:20.57 2.3g PassengerHelper 20564 rails 20 0 2539m 220m 9828 S 0.3 3.2 0:23.58 2.3g java 1423 nscd 20 0 877m 1464 972 S 0.0 0.0 0:03.89 876m nscd You can see, for instance, that jboss is reportedly using 5.2 gigs of swap space which is definitely impossible since there's only 1G allocated and none is being used (probably because there's still 1.8G of RAM free). And here's the results of uname -a: Linux xxx.yyy.zzz 2.6.35.14-106.53.amzn1.x86_64 #1 SMP Fri Jan 6 16:20:10 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux We're running an AMI based off of the default Amazon Linux AMI (Amazon Linux AMI release 2011.09, so some RHEL5 and RHEL 6) with not too many customizations and definitely no kernel-level customizations. Something here tells me that on this particular kernel/distribution, the reporting of swap or maybe even total memory usage isn't what it appears to be... Any help would be appreciated!

  • lamp -- edit PHP file but doesn't change web output -- including die()

    - by Reid W
    Server is standard Linux server on Amazon Web Services. Cent OS 5/Apache/PHP 5.3. No APC. It's worked fine for over a year, but now when I edit some but not all PHP files on the server using vi, the changes don't affect the web output. For example, I edit myfile.php and put a die() at the top, but when I load the page in my web browser, instead of the die() I see the content that would show up if the die() weren't there. svn updating the file in question doesn't help either. Files are on an Amazon EBS partition symlinked to /var/www/html. Just to reiterate -- this has worked fine for a long time. Restarting apache didn't help, nor did rebooting the server. What's weird is that it's just some of the files but not all. File ownership/permissions are the same for the "good" and "problem" files. I'm not a Linux newbie but am at a complete loss with this, and couldn't find anything on Google either. Any hints would be much appreciated!

  • Boot stuck at blinking cursor before GRUB - only works via BIOS boot menu

    - by delta1
    I have a new box running Debian Squeeze. Grub is installed on /dev/sda, but when booting up I just get a blinking cursor, before the Grub menu. I can only boot to grub successfully when I choose boot options (during post) and select that specific drive! I have made sure the correct drive is set to boot first in the BIOS. So Grub works, but the system won't boot to that drive automatically? Any ideas on what could cause this? Drives sda/b/c are all 2TB (sda runs the system with b/c as raid device md0) with the following partitions: $ cat /proc/partitions major minor #blocks name 8 0 1953514584 sda 8 1 977 sda1 8 2 9765625 sda2 8 3 6445313 sda3 8 4 1937302627 sda4 8 32 1953514584 sdc 8 16 1953514584 sdb 9 0 1953513424 md0 but # fdisk -l /dev/sda gives WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sda1 1 243202 1953514583+ ee GPT Any insight into this strange behaviour would be greatly appreciated.

  • Varnish going sick

    - by junke1990
    I'm having trouble with Varnish, it works for a couple of views and then just goes sick... The weird thing is that it does work for about 20 or 30 requests. If I call apache directly it works fine. I'm running Varnish Version: 3.0.3-1 on Debian Squeeze and, for now, Apache on port 80 and Varnish on port 8080 on the same server.. I'm using https://github.com/mattiasgeniar/varnish-3.0-configuration-templates as base for my VCLs and modified the VCLs to support Concrete5. Anyone any clue on how I should debug this? backend default { .host = "127.0.0.1"; .port = "80"; .connect_timeout = 1.5s; .first_byte_timeout = 45s; .between_bytes_timeout = 30s; .probe = { .url = "/"; .timeout = 1s; .interval = 10s; .window = 10; .threshold = 8; } } LOG 0 CLI - Rd ping 0 CLI - Wr 200 19 PONG 1353791312 1.0 0 CLI - Rd ping 0 CLI - Wr 200 19 PONG 1353791315 1.0 0 Backend_health - default Still sick 4--X-R- 0 8 10 0.000689 0.000000 HTTP/1.1 301 Moved Permanently (the 301 is because I check for www.)
