  • Squid reverse proxy array - siblings not communicating with each other

    - by V. Romanov
    I want to set up 2 squid servers to act as reverse proxy and cache for a webserver on our intranet. The load balancing will be done with DNS round robin or just different mappings for different clients. The thing is, I want both servers to try and contact each other to see if they have the object required in cache before contacting the webserver for it (the network that servers the webserver is the bottleneck and I'm trying to eliminate it) Both squids are configured the same, here are the relevant config lines : acl dvr1_cache_it_best_tv_com dstdomain dvr1.cache.it.best-tv.com acl squid1_it_best_tv_com dstdomain squid1.it.best-tv.com acl squid2_it_best_tv_com dstdomain squid2.it.best-tv.com http_access allow dvr1_cache_it_best_tv_com http_access allow squid1_it_best_tv_com http_access allow squid2_it_best_tv_com http_access allow all http_port 8081 accel defaultsite=dvr1.cache.it.best-tv.com cache_peer dvr1.origin.it.best-tv.com parent 80 0 no-query originserver name=Proxy_dvr1_origin_it_best_tv_com cache_peer squid1.it.best-tv.com sibling 8081 3130 weight=10 name=Proxy_Squid1_it_best_tv_com cache_peer squid2.it.best-tv.com sibling 8081 3130 weight=10 name=Proxy_Squid2_it_best_tv_com cache_peer_access Proxy_dvr1_origin_it_best_tv_com allow dvr1_cache_it_best_tv_com cache_peer_access Proxy_squid1_it_best_tv_com allow squid1_it_best_tv_com cache_peer_access Proxy_squid1_it_best_tv_com allow squid2_it_best_tv_com cache_peer_access Proxy_squid1_it_best_tv_com allow dvr1_cache_it_best_tv_com cache_peer_access Proxy_squid2_it_best_tv_com allow squid1_it_best_tv_com cache_peer_access Proxy_squid2_it_best_tv_com allow squid2_it_best_tv_com cache_peer_access Proxy_squid2_it_best_tv_com allow dvr1_cache_it_best_tv_com just to make it clear - dvr1.cache is the alias for the proxy servers. dvr1.origin is the web server. Both servers work, both serve content and cache it and work fine. However, when I clear the cache on one server and then access it, it gets the content from the parent (DVR1_ORIGIN) instead of going to the sibling squid. What did I configure wrong? Or perhaps I don't understand the architecture correctly? I read the squid manuals but as far as I see i did it all by the book and yet it doesn't work right. Any help will be appreciated!

  • Tape vs SSDs backups regarding long-term storage reliability

    - by user66131
    My question is very specifically about solid state drives, not regular hard drives. I would like to put in place a grandfather-father-son backup scheme, with the SSDs being used for the grandfather and father portions, and the yearly grandfather would be locked in a safe offsite for maybe 5-10 years. Can I expect that after this period of time the data would be preserved as well as it would be on a tape?

  • Computer Won't Boot Properly, unless in safe mode?

    - by Mr_CryptoPrime
    I bought a computer today and booted it up, but when I did I only got a blank screen. I checked to make sure it wasn't the monitor by connecting it to my old computer...it worked. I then tried connecting my monitor to both DVI ports and found that the bottom one did work. However, now it just boots up and says "loading windows" and then when the login screen is suppose to come up the screen just goes blank and monitor says "no input, check cord" (or something like that). I tried reinstalling windows and then I was able to log on normally. I used the CD's and reinstalled all the drivers, then rebooted...now I am stuck right back where I started. I tried taking out the RAM and inserting into different slots, that didn't fix anything. I was able to boot up into windows using safe-mode. I suspected that my ATI Radeon 6950 was the issue and downloaded the drivers, but I can't install them on safe-mode. Someone said to install C++ distr. and I tried doing that to fix driver installation problem of "failed to load detection driver" but it wouldn't let me do that either. Please someone help me, I don't want to have to deal with the evil redtape of sending it back to get a replacement!

  • How to create a mysql database that can contain any character, also different languages

    - by Jakke
    I'm trying to create a database that has to contain articles in different languages. I'm using Mariadb as my server and I know bits of SQL. My knowledge doesn't really cover details like the differences between engines like MyISAM, InnoDB etc or character sets like utf8/16/32, latin 5/7/etc. I do know that the character set has importance, I guess what I'm looking for is an all-encompassing character set and an engine that best deals with this type of content. Also, is there an advantage in storing articles in multiple data rows (equivalent of different pages) to make things a little faster, or would you store a whole article in a single data row. Or does that depend on the size of the articles? Sorry for my noobish question, I know the information is all out on the internet but it would take me quite a long time to research and get a grip on everything. Would be cool if someone with experience could give me a little head start and point me in the right direction. This is for a intranet site, consider the content to be somewhat like a blog (and no, I don't want wordpress or something similar at this point). Not sure if it matters, but I tend to create and manipulate my tables with phpmyadmin, I use apache as web server and it all runs on Linux.

  • What is the best way to secure MySQL data on a laptop *without* whole-disk-encryption?

    - by GJ
    I need to have the mysql data on my laptop stored in an encrypted state so that in case of the laptop being lost/stolen it will extremely difficult to recover the data without the password. I don't wish to use whole disk encryption, due to the performance impact it will have on other disk-intensive programs' usage. What could be the ideal solution for me balancing security and performance? Thanks!

  • Puppet and launchd services?

    - by Joel Westberg
    We have a production environment configured with Puppet, and want to be able to set up a similar environment on our development machines: a mix of Red Hats, Ubuntus and OSX. As might be expected, OSX is the odd man out here, and sadly, I'm having a lot of trouble with getting this to work. My first attempt was using macports, using the following declaration: package { 'rabbitmq-server': ensure => installed, provider => macports, } but this, sadly, generates the following error: Error: /Stage[main]/Rabbitmq/Package[rabbitmq-server]: Could not evaluate: Execution of '/opt/local/bin/port -q installed rabbitmq-server' returned 1: usage: cut -b list [-n] [file ...] cut -c list [file ...] cut -f list [-s] [-d delim] [file ...] while executing "exec dscl -q . -read /Users/$env(SUDO_USER) NFSHomeDirectory | cut -d ' ' -f 2" (procedure "mportinit" line 95) invoked from within "mportinit ui_options global_options global_variations" Next up, I figured I'd give homebrew a try. There is no package provider available by default, but puppet-homebrew seemed promising. Here, I got much farther, and actually managed to get the install to work. package { 'rabbitmq': ensure => installed, provider => brew, } file { "plist": path => "/Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist", source => "/usr/local/opt/rabbitmq/homebrew.mxcl.rabbitmq.plist", ensure => present, owner => root, group => wheel, mode => 0644, } service { "homebrew.mxcl.rabbitmq": enable => true, ensure => running, provider => "launchd", require => [ File["/Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist"] ], } Here, I don't get any error. But RabbitMQ doesn't start either (as it does if I do a manual load with launchctl) [... snip ...] Debug: Executing '/bin/launchctl list' Debug: Executing '/usr/bin/plutil -convert xml1 -o /dev/stdout /Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist' Debug: Executing '/usr/bin/plutil -convert xml1 -o /dev/stdout /var/db/launchd.db/com.apple.launchd/overrides.plist' Debug: /Schedule[weekly]: Skipping device resources because running on a host Debug: /Schedule[puppet]: Skipping device resources because running on a host Debug: Finishing transaction 2248294820 Debug: Storing state Debug: Stored state in 0.01 seconds Finished catalog run in 25.90 seconds What am I doing wrong?

  • MySQL Not Turning On

    - by Shalin Shah
    I have an amazon ec2 instance running on the Amazon Linux AMI and its a micro instance. I wanted to install Django onto my server so I entered these commands wget http://www.mlsite.net/blog/wp-content/uploads/2008/11/go wget http://www.mlsite.net/blog/wp-content/uploads/2008/11/django.conf chmod 744 go ./go So after I was done, I ran sudo service httpd restart and sudo service mysqld restart and This is what came up for mysqld: Stopping mysqld: [ OK ] MySQL Daemon failed to start. Starting mysqld: [FAILED] So I deleted the django files /usr/local/python2.6.8/site-packages/django_registration.egg and I tried finding the error and I found out that in my /etc/my.cnf for the socket, it said socket=/var/lock/subsys/mysql.sock so I went to /var/lock/subsys/ and there was no mysql.sock. I tried creating one using vim but it still didn't work. Then I checked the error log and it said Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) So I am pretty much lost right now. I know it has something to do with mysql.sock If you might know a reason why this was caused could you please let me know? I have a wordpress site on my server, so i kind of need MySQL to work. Thanks!

  • How can I "filter" postfix-generated bounce messages?

    - by Flimzy
    We are using postfix 2.7 and custom SMTPD (based on qpsmtpd) in highly customized configuration for spam filtering. We have a new requirement to filter postfix-generated bounces through our custom qpsmtpd process (not so much for content filtering, but to process these bounces accordingly). Our current configuration looks (in part) like this: main.cf (only customizations shown): 2526 inet n - - - 0 cleanup pickup fifo n - - 60 1 pickup -o content_filter=smtp:127.0.0.2 Our smtpd injects messages to postfix on port 2526, by speaking directly to the cleanup daemon. And the custom pickup command instructs postfix to hand off all locally-generated mail (from cron, nagios, or other custom scripts) to our custom smtpd. The problem is that this configuration does not affect postfix generated bounce messages, since they do not go through the pickup daemon. I have tried adding the same content_filter option to the bounce daemon commands, but it does not seem to have any effect: bounce unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 defer unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 trace unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 For reference, here is my main.cf file, as well: biff = no # TLS parameters smtpd_tls_loglevel = 0 smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache smtp_tls_security_level = may mydestination = $myhostname alias_maps = proxy:pgsql:/etc/postfix/dc-aliases.cf transport_maps = proxy:pgsql:/etc/postfix/dc-transport.cf # This is enforced on incoming mail by QPSMTPD, so this is simply # the upper possible bound (also enforced in defaults.pl) message_size_limit = 262144000 mailbox_size_limit = 0 # We do our own message expiration, but if we set this to 0, then postfix # will try each mail delivery only once, so instead we set it to 100 days # (which is the max postfix seems to support) maximal_queue_lifetime = 100d hash_queue_depth = 1 hash_queue_names = deferred, defer, hold I also tried adding the internal_mail_filter_classes option to main.cf, but also tono affect: internal_mail_filter_classes = bounce,notify I am open to any suggestions, including handling our current content-filtering-loop in a different way. If it's not clear what I'm asking, please let me know, and I can try to clarify.

  • PDF form (not) saving

    Hi, I've created a form in a PDF with Adobe Acrobat Pro. When empy, I want to use it as a template which the user opens, fills in, and saves as a copy to preserve the blank state of the template. Here's the trick : I found both ways to make the document read only - the user can't save the form value, only print them make the document writeable, but in this case the document acting as a template can be modified too. Any ideas? Thanks.

  • CloudFront with Custom Origin and ELB

    - by kmfk
    We are using CloudFront for our static assets but also wanted to allow for Gzip. We set up a new distribution with a custom origin pointing back to our application servers which are behind a elastic load balancer. We manually keep the files in sync across the cluster and update them when we publish. However, with this set up, we get nothing but Miss and RefreshHits from CloudFront, which so far has defeated the purpose. Is there any additional settings in order to use an ELB as your custom origin? In the docs, it references this as a viable solution. It appears when we point the distribution to a single server in our production cluster, cloudfront properly caches our assets. Is it possible that the sticky sessions cookie and the subsequent header that gets added by it could be an issue? Cache-Control: no-cache="set-cookie" //Added by load balancer Any ideas? FYI - currently, we have our custom origin pointing to a single EC2 instance, so caching is working correctly - in case you try to curl the file below. Example headers: curl -I http://static.quick-cdn.com/css/9850999.css HTTP/1.0 200 OK Accept-Ranges: bytes Cache-Control: max-age=3700 Cache-Control: no-cache="set-cookie" Content-Length: 23038 Content-Type: text/css Date: Thu, 12 Apr 2012 23:03:52 GMT Last-Modified: Thu, 12 Apr 2012 23:00:14 GMT Server: Apache/2.2.17 (Ubuntu) Vary: Accept-Encoding X-Cache: RefreshHit from cloudfront X-Amz-Cf-Id: K_q7Zy3_jdzlEJ85ukELVtdx1GmuXqApAbZZ7G0fPt0mxRMqPKX5pQ==,RzJmPku-rEIO9WlvuSoKa8hiAaR3dLk5KC4cQMWWrf_MDhmjWe8n6A== Via: 1.0 28c34f9fbf559a21ee16594849e4fc9c.cloudfront.net (CloudFront) Connection: close

  • Gentoo box can't cURL or ping after restarting net.eth1

    - by Curlybraces
    Hi all, the following is completely baffling me. We currently have a gentoo box which acts as our LAMP, DNS, DHCP server. This is assigned a static IP on the network. This server is connected directly to the internet via a BT BusinessHub Router. The server is also connected to a patch panel/switch port which connects the remaining office (around 10 PC's) to the server. Everything has been plain sailing until the other day when the server was restarted. For some reason now only portions of network accessibility is available depending on which ethernet device was last restarted. Restarting net.eth0 allows the office server to cURL, ping, etc but stops all networked PC's from accessing the internet. Then restarting net.eth1 restores all internet to the network but stops the server from curling, pinging, etc again. However, even when the server can't ping, curl, etc, I can still remote SSH and remote MySQL connect from the server command line to other external servers that we own. Here's my route map (router is 192.168.1.254): Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 192.168.1.254 0.0.0.0 UG 0 0 0 eth1 Here's my /etc/conf.d/net: iface_eth0="192.168.1.99 broadcast 192.168.1.255 netmask 255.255.255.0" iface_eth1="dhcp" None of the above have ever been changed however.

  • Redirect from folder containing website

    - by Sam
    I have a website reached from this url: http://www.mysite.com/cms/index.php being served from this directory: public_html/cms/index.php In public_html I have this .htaccess RewriteRule (.*) cms/$1 [L] Which lets me get to the site like this: http://www.mysite.com/index.php But now if I reference the 'old' address, I'd like to redirect to the rewritten address with a permanent redirect code. for example: http://www.mysite.com/cms/?q=node/1 is redirected to... http://www.mysite.com/?q=node/1 How can I make this happen?

  • How to make a persistent acknowledgment in Icinga/Nagios?

    - by blerontin
    I am using Icinga (Nagios fork) to also monitor uptime of external hosts and services. Currently when looking at the "Critical" count I find it difficult to decide if an internal service is affected (I should take immediate action) or an external service (I just acknowledge the problem). Is there a way to keep a problem acknowledgement for future down-times of the checked host/service? Is there some way to auto-acknowledge the state change of external hosts/services?

    I am trying to pass a PCI compliance test, and I'm getting a single "high risk vulnerability". The problem is described as: Information on the machine which a web server is located is sometimes included in the header of a web page. Under certain circumstances that information may include local information from behind a firewall or proxy server such as the local IP address. It looks like Nginx is responding with: Service: https Received: HTTP/1.1 302 Found Cache-Control: no-cache Content-Type: text/html; charset=utf-8 Location: http://ip-10-194-73-254/ Server: nginx/1.0.4 + Phusion Passenger 3.0.7 (mod_rails/mod_rack) Status: 302 X-Powered-By: Phusion Passenger (mod_rails/mod_rack) 3.0.7 X-Runtime: 0 Content-Length: 90 Connection: Close <html><body>You are being <a href="http://ip-10-194-73-254/">redirect ed</a>.</body></html> I'm no expert, so please correct me if I'm wrong: but from what I gathered, I think the problem is that the Location header is returning http://ip-10-194-73-254/, which is a private address, when it should be returning our domain name (which is ravn.com). So, I'm guessing I need to either hide or replace the Location header somehow? I'm a programmer and not a server admin so I have no idea what to do... Any help would be greatly appreciated! Also, might I add that we're running more than 1 server, so the configuration would need to be transferable to any server with any private address.

  • Ubuntu's 'drag window to side of screen expand' in a hotkey

    - by Bentley4
    In ubuntu(using version 12.04), when you drag a window to the left or right side of your screen the window gets auto-maximized in height and is half of the screen on the left or right side respectively. What would be super useful imo is a hotkey that autodetects what side of the screen your window is on the most and then expands it to a state identical to the one described in the above paragraph. Has anyone programatically done this before? If not, how would you go about achieving this?

  • bind9 - forwarders are not working

    - by Sarp Kaya
    I am experiencing an issue with bind. If i want to resolve any domain name that is on the zone file. It works fine. However, when I try to resolve anything that does not belong to the zone file. I know that actual DNS servers that are being forwarded are working fine. But somehow bind9 fails to use them. The content of /etc/bind/named.conf.options is: options { directory "/var/cache/bind"; forwarders { 131.181.127.32; 131.181.59.48; }; dnssec-validation auto; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; }; I have also tried to use only one ip address and it still did not work. also the content of /etc/bind/named.conf is: include "/etc/bind/named.conf.options"; include "/etc/bind/named.conf.local"; include "/etc/bind/named.conf.default-zones"; So there is no problem with including options file. Any recommendations for fixing this problem?
