  • Providing DNS redirection to honeypot server for known bad domains

    - by syn-
    Currently running BIND on RHEL 5.4 and am looking for a more efficient manner of providing DNS redirection to a honeypot server for a large (30,000+) list of forbidden domains. Our current solution for this requirement is to include a file containing a zone master declaration for each blocked domain in named.conf. Subsequently, each of these zone declarations point to the same zone file, which resolves all hosts in that domain to our honeypot servers. ...basically this allows us to capture any "phone home" attempts by malware that may infiltrate the internal systems. The problem with this configuration is the large amount of time taken to load all 30,000+ domains as well as management of the domain list configuration file itself... if any errors creep into this file, the BIND server will fail to start, thereby making automation of the process a little frightening. So I'm looking for something more efficient and potentially less error prone. named.conf entry: include "blackholes.conf"; blackholes.conf entry example: zone "bad-domain.com" IN { type master; file "/var/named/blackhole.zone"; allow-query { any; }; notify no; }; blackhole.zone entries: $INCLUDE std.soa @ NS ns1.ourdomain.com. @ NS ns2.ourdomain.com. @ NS ns3.ourdomain.com.                        IN            A                192.168.0.99 *                      IN            A                192.168.0.99

  • phpMyAdmin causes php-fpm worker to restart (502 Bad Gateway)

    - by rndbit
    I am trying to set up a test site for myself. Everything works fine except phpMyAdmin. php installation loads my test site scripts, they work fine, however trying to load phpMyAdmin i get 502 Bad Gateway error. Judging from logs (that are not too helpful) it seems that php-fpm worker is crashing each time phpmyadmin is being accessed. No clue how or why.. Does anyone have any idea? nginx log: *3 recv() failed (104: Connection reset by peer) while reading response header from upstream, And php-fpm log: [07-Jun-2012 14:19:51] WARNING: [pool www] child 32179 exited on signal 11 (SIGSEGV) after 3.217902 seconds from start [07-Jun-2012 14:19:51] NOTICE: [pool www] child 32351 started My nginx conf: user nginx; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; keepalive_timeout 65; fastcgi_buffers 8 16k; fastcgi_buffer_size 32k; include /etc/nginx/conf.d/*.conf; server { listen 443 ssl; listen 80; server_name testsite.net www.testsite.net; ssl on; ssl_certificate /var/www/html/admin/ssl/certificate.pem; ssl_certificate_key /var/www/html/admin/ssl/privatekey.pem; ssl_session_timeout 1m; ssl_protocols SSLv2 SSLv3 TLSv1; ssl_ciphers HIGH:!aNULL:!MD5:!kEDH; ssl_prefer_server_ciphers on; access_log off; location ~ \.php$ { root /var/www/html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include /etc/nginx/fastcgi_params; } location / { root /var/www/html; index index.php; } } } php.ini is standard, with cgi.fix_pathinfo=0 php-fpm.conf: include=/etc/php-fpm.d/*.conf [global] pid = /var/run/php-fpm/php-fpm.pid error_log = /var/log/php-fpm/error.log log_level = notice php-fpm.d/www.conf: [www] listen = 127.0.0.1:9000 listen.allowed_clients = 127.0.0.1 user = nginx group = nginx pm = dynamic pm.max_children = 10 pm.start_servers = 1 pm.min_spare_servers = 1 pm.max_spare_servers = 10 slowlog = /var/log/php-fpm/www-slow.log php_flag[display_errors] = on php_admin_value[error_log] = /var/log/php-fpm/www-error.log php_admin_flag[log_errors] = on

  • 502 Bad Gateway with nginx + apache + subversion + ssl (SVN COPY)

    - by theplatz
    I've asked this on stackoverflow, but it may be better suited for serverfault... I'm having a problem running Apache + Subversion with SSL behind an Nginx proxy and I'm hoping someone might have the answer. I've scoured google for hours looking for the answer to my problem and can't seem to figure it out. What I'm seeing are "502 (Bad Gateway)" errors when trying to MOVE or COPY using subversion; however, checkouts and commits work fine. Here are the relevant parts (I think) of the nginx and apache config files in question: Nginx upstream subversion_hosts { server 127.0.0.1:80; } server { listen x.x.x.x:80; server_name hostname; access_log /srv/log/nginx/http.access_log main; error_log /srv/log/nginx/http.error_log info; # redirect all requests to https rewrite ^/(.*)$ https://hostname/$1 redirect; } # HTTPS server server { listen x.x.x.x:443; server_name hostname; passenger_enabled on; root /path/to/rails/root; access_log /srv/log/nginx/ssl.access_log main; error_log /srv/log/nginx/ssl.error_log info; ssl on; ssl_certificate server.crt; ssl_certificate_key server.key; add_header Front-End-Https on; location /svn { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; set $fixed_destination $http_destination; if ( $http_destination ~* ^https(.*)$ ) { set $fixed_destination http$1; } proxy_set_header Destination $fixed_destination; proxy_pass http://subversion_hosts; } } Apache Listen 127.0.0.1:80 <VirtualHost *:80> # in order to support COPY and MOVE, etc - over https (443), # ServerName _must_ be the same as the nginx servername # http://trac.edgewall.org/wiki/TracNginxRecipe ServerName hostname UseCanonicalName on <Location /svn> DAV svn SVNParentPath "/srv/svn" Order deny,allow Deny from all Satisfy any # Some config omitted ... </Location> ErrorLog /var/log/apache2/subversion_error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog /var/log/apache2/subversion_access.log combined </VirtualHost> From what I could tell while researching this problem, the server name has to match on both the apache server as well as the nginx server, which I've done. Additionally, this problem seems to stick around even if I change the configuration to use http only.

  • php-fpm or nginx: bad gateway

    - by John Tate
    I'm getting a bad gateway error all the sudden for a site. I didn't change the configuration for the site, I just added a new server config where I put them under /etc/nginx/servers and it stopped working. The new server works, and there is no conflict between the php-fpm listen addresses. server { listen 80; server_name obfuscated.onion; location = / { root /var/www/sites/obfuse; index index.php; } location / { root /var/www/sites/obfuse; index index.php; if (!-f $request_filename) { rewrite ^(.*)$ /index.php?q=$1 last; break; } if (!-d $request_filename) { rewrite ^(.*)$ /index.php?q=$1 last; break; } } error_page 404 /index.php; location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico)$ { root /var/www/sites/obfuse; access_log off; expires 30d; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/sites/obfuse$fastcgi_script_name; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param PATH_INFO $fastcgi_script_name; include fastcgi_params; } } There is nothing unusual in php-fpm's log even when I raised the level to debug.

  • 40k Event Log Errors an hour Unknown Username or bad password

    - by ErocM
    I am getting about 200k of these an hour: An account failed to log on. Subject: Security ID: SYSTEM Account Name: TGSERVER$ Account Domain: WORKGROUP Logon ID: 0x3e7 Logon Type: 4 Account For Which Logon Failed: Security ID: NULL SID Account Name: administrator Account Domain: TGSERVER Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc0000064 Process Information: Caller Process ID: 0x334 Caller Process Name: C:\Windows\System32\svchost.exe Network Information: Workstation Name: TGSERVER Source Network Address: - Source Port: - Detailed Authentication Information: Logon Process: Advapi Authentication Package: Negotiate Transited Services: - Package Name (NTLM only): - Key Length: 0 This event is generated when a logon request fails. It is generated on the computer where access was attempted. The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe. The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network). The Process Information fields indicate which account and process on the system requested the logon. The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases. The authentication information fields provide detailed information about this specific logon request. - Transited services indicate which intermediate services have participated in this logon request. - Package name indicates which sub-protocol was used among the NTLM protocols. - Key length indicates the length of the generated session key. This will be 0 if no session key was requested. On my server... I changed my adminstrative username to something else and since then I've been inidated with these messages. I found on http://technet.microsoft.com/en-us/library/cc787567(v=WS.10).aspx that the 4 means "Batch logon type is used by batch servers, where processes may be executing on behalf of a user without their direct intervention." which really doesn't shed any light on it for me. I checked the services and they are all logging in as local system or network service. Nothing for administrator. Anyone have any idea how I tell where these are coming from? I would assume this is a program that is crapping out... Thanks in advance!

  • Is it bad to redirect http to https?

    - by jasondavis
    I just installed an SSL Certificate on my server. I use a web hosting panel called ZPanel that is an open source project. It then set up a redirect for all traffic on my domain on Port 80 to redirect it to Port 443. In other words, all my http://example.com traffic is now redirected to the appropriate https://example.com version of the page. The redirect is done in my Apache Virtual Hosts file with something like this... RewriteEngine on ReWriteCond %{SERVER_PORT} !^443$ RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R,L] My question is, are there any drawbacks to using SSL? Since this is not a 301 Redirect, will I lose link juice/ranking in search engines by switching to https? I appreciate the help. I have always wanted to set up SSL on a server, just for the practice of doing it, and I finally decided to do it tonight. It seems to be working well so far, but I am not sure if it's a good idea to use this on every page. My site is not eCommerce and doesn't handle sensitive data; it's mainly for looks and the thrill of installing it for learning. UPDATED ISSUE Strangely Bing creates this screenshot from my site now that it is using HTTPS everywhere...

  • Why is my spawned process still causing IntelliJ to wait?

    - by itsadok
    I'm trying to start a server as part of an Ant artifact. Here are the relevant lines: <exec dir="." executable="cmd.exe" spawn="true"> <arg line="/c c:\Java\james-2.3.2\bin\debug.bat" /> </exec> If I start it with ant from the command line, a process is spawned and I get a command prompt and everything seems fine. However, if I start it from IntelliJ 6, my IDE, the build stays alive until I kill the server. Here's the line IntelliJ uses to start ant: C:\Java\jdk1.6.0_02\bin\java -Xmx128m -Dant.home=C:\Java\apache-ant-1.7.1 -Dfile.encoding=UTF-8 -classpath "C:\Java\apache-ant-1.7.1\lib\ant-antlr.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-bcel.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-bsf.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-log4j.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-oro.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-regexp.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-resolver.jar;C:\Java\apache-ant-1.7.1\lib\ant-commons-logging.jar;C:\Java\apache-ant-1.7.1\lib\ant-commons-net.jar;C:\Java\apache-ant-1.7.1\lib\ant-jai.jar;C:\Java\apache-ant-1.7.1\lib\ant-javamail.jar;C:\Java\apache-ant-1.7.1\lib\ant-jdepend.jar;C:\Java\apache-ant-1.7.1\lib\ant-jmf.jar;C:\Java\apache-ant-1.7.1\lib\ant-jsch.jar;C:\Java\apache-ant-1.7.1\lib\ant-junit.jar;C:\Java\apache-ant-1.7.1\lib\ant-launcher.jar;C:\Java\apache-ant-1.7.1\lib\ant-netrexx.jar;C:\Java\apache-ant-1.7.1\lib\ant-nodeps.jar;C:\Java\apache-ant-1.7.1\lib\ant-starteam.jar;C:\Java\apache-ant-1.7.1\lib\ant-stylebook.jar;C:\Java\apache-ant-1.7.1\lib\ant-swing.jar;C:\Java\apache-ant-1.7.1\lib\ant-testutil.jar;C:\Java\apache-ant-1.7.1\lib\ant-trax.jar;C:\Java\apache-ant-1.7.1\lib\ant-weblogic.jar;C:\Java\apache-ant-1.7.1\lib\ant.jar;C:\Java\apache-ant-1.7.1\lib\xercesImpl.jar;C:\Java\apache-ant-1.7.1\lib\xml-apis.jar;C:\Java\jdk1.6.0_02\lib\tools.jar;C:\Program Files\JetBrains\IntelliJ IDEA 6.0\lib\idea_rt.jar" com.intellij.rt.ant.execution.AntMain2 -logger com.intellij.rt.ant.execution.IdeaAntLogger2 -inputhandler com.intellij.rt.ant.execution.IdeaInputHandler -buildfile C:\Java\Projects\CcMailer\ccmailer.xml jar I suspect the inputhandler parameter has something to do with the problem, but if I run it myself the problem is not reproduced. Either way, I have only limited control over what IntelliJ does. My question is: how does IntelliJ even know the process is running? The Ant process is long gone. Is there a way to start a subprocess in a more sneaky way, so that IntelliJ won't even know there's anything to wait around for? Here's what I've tried so far: I tried using the start command, like this: <exec dir="." executable="cmd.exe" spawn="true"> <arg line="/c start cmd /c c:\Java\james-2.3.2\bin\debug.bat" /> </exec> I also tried using python, with code like this: import os.path import subprocess subprocess.Popen(["cmd.exe", "/c", "debug.bat"], stdin=open(os.path.devnull), stdout=open(os.path.devnull, "w"), stderr=subprocess.STDOUT) To no avail. The build window always stays up until I kill the server. Any ideas?

  • Javascript crazy idea finding a node

    - by Louis
    I had a crazy (but so crazy that it just might work) idea where every element on a page is created in javascript but given an ID which is a hash of its path in the DOM. So instead of searching through the DOM to find an element, you hash the path and then getElementById() with that hash. Problem with this is getting the path might be more expensive than searching the DOM in the first place. Any ideas how this could be done or if it is just plain stupid?

  • Are iframes a terrible idea?

    - by jamtoday
    I'm building a widget, and I've been using iframes to present content within it. At some point, I might start serving third party HTML and JS, so I thought iframes would be a good idea. It does make the widget javascript a little more complicated, and I'm concerned that this might not be the best implementation. Do you have any advice? It would be a huge help to hear what other people think about iframes.

    hi there I have an entity and it seems like using DateTime as the Id would be a good suit, however I there is this strange feeling that that it might be a terrible idea ( tho i cant come up with any logical reason as to why), This is an immutable object ( ie once the value is recorded it shouldn't really change ) So DateTime as id field in NHibernate yay or Nay? I would appreciate your comments on this

    - by Andrew Welch
    Hi, This is an idea more than a question, but I thought it would be the right community. I really like mindmapping as a way to organise information and I think it would be really cool to have a piece of software that allowed you to organise bookmarks into a dynamic mind map. If I get time I would start to create such a thing. Any thoughts or does it already exist? Thanks Andy

From some email clients I am getting the following 'bad signature data' error: Jun 7 02:10:09 ip-10-194-99-63 dkim-filter[27964]: (unknown-jobid) no signing domain match for `gmail.com' Jun 7 02:10:09 ip-10-194-99-63 dkim-filter[27964]: (unknown-jobid) no signing subdomain match for `gmail.com' Jun 7 02:10:09 ip-10-194-99-63 dkim-filter[27964]: (unknown-jobid) no signing keylist match for `[email protected]' Jun 7 02:10:09 ip-10-194-99-63 dkim-filter[27964]: (unknown-jobid) not internal Jun 7 02:10:09 ip-10-194-99-63 dkim-filter[27964]: (unknown-jobid) not authenticated Jun 7 02:10:09 ip-10-194-99-63 dkim-filter[27964]: (unknown-jobid) mode select: verifying Jun 7 02:10:09 ip-10-194-99-63 dkim-filter[27964]: BA6E210015D: bad signature data Jun 7 02:10:10 ip-10-194-99-63 postfix/cleanup[30131]: BA6E210015D: milter-reject: END-OF-MESSAGE from mail-pv0-f176.google.com[74.125.83.176]: 5.7.0 bad DKIM signature data; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail-pv0-f176.google.com> can anybody give me any clue why I am getting the above error in my postfix logs and what remedies I can put in to rectify or workaround this or warn the sender.

  • Interface Builder caching bad data (voodoo)

    - by Ryan Townshend
    Sometimes IB will hold onto old or bad references, and I cannot seem to remove or edit them. EDIT I have made this a wiki question with the intention of gathering more data on the phenomenon. Answers involving situations where other coders have encountered this are welcome. This happened to me again last night with a table controller. When I created a spike project to try and reproduce the error, the system worked the way I anticipated. Then back in the actual project the bad behavior continued, even if I remove the xib file and all controllers involved. Creating a whole new project with none of the original (problematic) xib and nib files worked correctly. This question is not about the specifics of this incident but about this type of incident in IB. Does anyone know more about this type of bad IB behaviour, and possibly a more stylish way to to eliminate it than nuking the project? Note, removing the offending IB files and recreating them in the same project has not solved this for me in the past, only whole new projects. Answers regarding examples of when/how this glitch has been observed/created are welcome as well.
