  • How to tunnel all traffic through Tor?

    - by HappyDeveloper
    All I want is be able to use flash and javascript while using Tor (I don't intend to use it for torrents) Normally, using flash with Tor is not recommended because firefox plugins run outside of the sandbox, so the browser's proxy settings don't apply to them, and can reveal your real IP. But I think it should be possible to also redirect flash to the same socket as the browser, and block the other outgoing ports just in case. Any ideas on how to do this?

  • Cisco VPN stops Windows 7 Browsing

    - by Sharjeel Sayed
    My browsing and other 'internet' activity (dropbox,digsby etc) halts when I connect to my office VPN using Cisco Systems VPN client Version 5.0.04.0300 on my Windows 7 Ultimate.The only option left for me at this time is to use my office proxy to enable the connection back. I tried doing the ucheck "Use default gateway on remote network" solution as mentioned on a previous post Windows 7 VPN stops web browser but I don't see that option on the properties of "Cisco systems VPN adapter" connection properties. Here is the screenshot

  • Price drop patterns

    - by doug
    I'm looking to buy a new laptop, and i don't need the top hi-tech because I'll use it for office type applications. In this case, the CPU and RAM are those who are mostly used. For example Intel i3 CPU was launched in Jan 2010 and in this case, the prices for Core Duo technology will drop. Do you know when or which are the signs? Can we talk about such a pattern?

  • Is there a .NET 4.0 offline install?

    - by TrueWill
    I'm trying to install .NET 4.0 on some VMs using dotNetFx40_Full_setup.exe and am getting error 0x800C0005. The issue likely involves the firewall/proxy/security configuration. Rather than dealing with that, does Microsoft have an offline install available yet? I've searched but not found one.

    I noticed a pattern of errors while trying to install PyMedia and Python Audio Tools. For both modules I run the following: $ python setup.py install Then I get a series of compilation errors, and then this: lipo: can't figure out the architecture type of: /var/folders/Kx/Kxxj4868HGi6VMhZLPyZN++++TI/-Tmp-//cch1y9AO.out error: command '/usr/bin/gcc-4.2' failed with exit status 1 I'm running Mac OS X 10.5, and this happens whether I'm using gcc-4.0 or gcc-4.2, Mac-Python 2.5 or 2.6, and MacPorts-Python 2.6.

  • Pidgin To Shoretel Call Manager IM

    - by ocatenac
    Is anyone out there using Pidgin to connect with Shoretel's Instant Messaging? Shoretel 9.2. According to one of the docs I found on Shoretel's website, it should be connecting as a SIMPLE client but so far no dice. It keeps getting an error resolving the server. There's no proxy involved that I know of. I was just wondering if anyone else had this particular configuration and if they'd made it work correctly.

  • Deploying Django App with Nginx, Apache, mod_wsgi

    - by JCWong
    I have a django app which can run locally using the standard development environment. I want to now move this to EC2 for production. The django documentation suggests running with apache and mod_wsgi, and using nginx for loading static files. I am running Ubuntu 12.04 on an Ec2 box. My Django app, "ddt", contains a subdirectory "apache" with ddt.wsgi import os, sys apache_configuration= os.path.dirname(__file__) project = os.path.dirname(apache_configuration) workspace = os.path.dirname(project) sys.path.append(workspace) sys.path.append('/usr/lib/python2.7/site-packages/django/') sys.path.append('/home/jeffrey/www/ddt/') os.environ['DJANGO_SETTINGS_MODULE'] = 'ddt.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() I have mod_wsgi installed from apt. My apache/httpd.conf contains NameVirtualHost *:8080 WSGIScriptAlias / /home/jeffrey/www/ddt/apache/ddt.wsgi WSGIPythonPath /home/jeffrey/www/ddt <Directory /home/jeffrey/www/ddt/apache/> <Files ddt.wsgi> Order deny,allow Allow from all </Files> </Directory> Under apache2/sites-enabled <VirtualHost *:8080> ServerName www.mysite.com ServerAlias mysite.com <Directory /home/jeffrey/www/ddt/apache/> Order deny,allow Allow from all </Directory> LogLevel warn ErrorLog /home/jeffrey/www/ddt/logs/apache_error.log CustomLog /home/jeffrey/www/ddt/logs/apache_access.log combined WSGIDaemonProcess datadriventrading.com user=www-data group=www-data threads=25 WSGIProcessGroup datadriventrading.com WSGIScriptAlias / /home/jeffrey/www/ddt/apache/ddt.wsgi </VirtualHost> If I am correct, these 3 files above should correctly allow my django app to run on port 8080. I have the following nginx/proxy.conf file proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; Under nginx/sites-enabled server { listen 80; server_name www.mysite.com mysite.com; access_log /home/jeffrey/www/ddt/logs/nginx_access.log; error_log /home/jeffrey/www/ddt/logs/nginx_error.log; location / { proxy_pass http://127.0.0.1:8080; include /etc/nginx/proxy.conf; } location /media/ { root /home/jeffrey/www/ddt/; } } If I am correct these two files should setup nginx to take requests on the HTTP port 80, but then direct requests to apache which is running the django app on port 8080. If i go to mysite.com, all I see is Welcome to Nginx! Any advice for how to debug this?

  • Setting up my own VPN or SSH server

  • Apache Mod_rewrite rule working on one server, but not another

    - by Mason
    I am using mod_jk and mod_rewrite on httpd 2.2.15. I have a rule.... RewriteCond %{REQUEST_URI} !^/video/play\.xhtml.* RewriteRule ^/video/(.*) /video/play.xhtml?vid=$1 [PT] I just want to rewrite something like /video/videoidhere to /video/play.xhtml?vid=videoidhere This works perfectly on my developer machine, but on production I get a 404 (generated by Jboss, not Apache). here is the tail of access.log and rewrite.log on prod (broken). the rewrite.log is exactly the same on dev(working) applying pattern '^/video/(.*)' to uri '/video/46279d4daf5440b2844ec831413dcc3b' RewriteCond: input='/video/46279d4daf5440b2844ec831413dcc3b' pattern='!^/video/play\.xhtml.*' => matched rewrite '/video/46279d4daf5440b2844ec831413dcc3b' -> '/video/play.xhtml?vid=46279d4daf5440b2844ec831413dcc3b' split uri=/video/play.xhtml?vid=46279d4daf5440b2844ec831413dcc3b -> uri=/video/play.xhtml, args=vid=46279d4daf5440b2844ec831413dcc3b forcing '/video/play.xhtml' to get passed through to next API URI-to-filename handler "GET /video/46279d4daf5440b2844ec831413dcc3b HTTP/1.1" 404 420 "-" "Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.6) Gecko/20100628 Ubuntu/10.04 (lucid) Firefox/3.6.6" I can access http://www.fivi.com/video/play.xhtml?vid=46279d4daf5440b2844ec831413dcc3b but not /video/46279d4daf5440b2844ec831413dcc3b Both server are even using the EXACT same httpd.conf, and modules.

  • Millions of SYN_RECV connections, no DDoS

    - by ThomK
    We have such server structure: reverse proxy (nginx) - worker (uwsgi) - postgresql / memcached. All servers are in local network behind router, with NATed external ip:ports (http/s 80/443 to proxy, and ssh 22 to all servers). Problem is, that sometimes proxy server netstat reports MILLIONS of SYN_RECV connections. From same IP / same ports. Like that: nginx ~ # netstat -n | grep 83.238.153.195 tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV tcp 0 0 192.168.1.1:80 83.238.153.195:3107 SYN_RECV [...] And this is not DDoS, because all IPs affected belongs to our website users. On side note, users says that it's not affecting them. Website is online and working, but... that particular one (from example above) told me that website is down and Firefox can't connect.

  • URL rewriting with TomCat

    - by Tudor Olariu
    I am looking to rewrite an incoming url request on TomCat with the Tuckey rewriter: <rule> <from>/OutputFile?sourceArticleId=([0-9]+)</from> <to>/app/clipping/get/$1</to> </rule> the "?" question mark fails the regexp pattern matching. How can I properly escape it or what is the correct solution for this?

  • Nagios not accepting regex in command

    - by Creshal
    I have this command defined: define command{ command_name check_http_sane command_line $USER1$/check_http -H $HOSTNAME$ -r "HTTP/1.1 (200|301|302|303|304|307|401|418|426)" } When I run it manually on command line, it works fine, but nagios (2.6) reports a "pattern not found" error. Do I need to escape something? Edit: As stated below, I solved it by replacing check_http with my own script which works (good enough for our use case, anyway). Script: http://pastebin.com/hNmz6Wa1

  • Make Apache Ignore Domains on the Same Server (Ubuntu 9.10). How?

    - by vladikoff
    Hello, I'm running Apache on Ubuntu 9.10. I want Apache to ignore certain domains on my server, and let other HTTP servers make full use of them. I've used mod_proxy and other Apache modules to configure the proxy/redirect to certain ports but sometimes that's too much work or doesn't work properly. Example: Server 00.00.000.000 domain1.com:80 - Apache domain2.com:80 - Apache domain3.com:80 - Webrick domain4.com:80 - Jetty Is this possible?

  • How do you set up SSL and Nginx Proxying?

    - by Jason Christa
    I have Nginx listening to traffic on port 80 and proxying certain request to Apache over port 8080. I am going to set up Nginx to listen to port 443 for https traffic, but my question is how should the proxying be done now? Does the proxy to Apache need to be https or has Nginx already decoded it so I can keep sending it to Apache over port 8080. BTW, Apache is running with the least amount of modules installed possible and has currently has no SSL related modules, would I need to install any?

  • Why is my new Phenom II 965 BE not significantly faster than my old Athlon 64 X2 4600+?

    - by Software Monkey
    I recently rebuilt my 5 year old computer. I upgraded all core components, in particular from an Athlon 64 X2 4600+ at 2.4 GHz with DDR2 800 to a Phenom II 965 BE (quad core) at 3.6 GHz with DDR3 1333 (actually 1600, but testing consistently detected memory errors at 1600). The motherboard is also much newer and better. The HDD's (x3), DVD writer and card reader are the same. The BIOS memory config is auto-everything except the base timing which I overrode to 1T instead of 2T. The BIOS CPU multiplier is slightly over-clocked to 3.6 GHz from the stock 3.4 GHz. I noticed compiling Java is slower than I expected. As it happens I have some (single-threaded) Java pattern-matching code which is CPU and memory bound and for which I have performance numbers recorded on a number of hardware platforms, including my old system. So I did a test run on the new equipment and was stunned to find that the numbers are only slightly better than my old system, about 25%. The data set it is operating on is a 148,975 character array, which should easily fit in caches, but in any event the new CPU has larger caches all around. The system was, of course, otherwise idle for the test and the test run is a timed 10 seconds to eliminate scheduling anomalies. A long while ago, when I upgraded only memory from DD2 667 to DDR2 800 there was no change in performance of this test, which subjectively supports that the test cycle does not need to (significantly) access main memory, but yes it is creating and garbage collecting a large number of objects in the process of this test (low millions of matches are found for the pattern set). I am about 99.999% certain the code hasn't changed since I last ran it on 2009-03-17 - but I can't easily retest the old hardware, because it is currently in pieces on my work-bench waiting to be built into a new computer for my kids. Note that Windows (XP) reports a CPU speed of 795 MHz unless I have some thing running. With stuff running it seems to jump all over the place each time I use ALT-Pause to display the system properties, everywhere from 795 MHz to 3.4 Ghz. So why might my shiny new hardware under-performing so badly? EDIT: The old memory was Mushkin DDR2 800 with timings set for auto which should have been 5-5-5-12. The new memory is Corsair DDR3 1600, running at 1333 with timings also auto which are 9-9-9-21. In both cases they are a paired set of dual channel DIMMs. I was waiting to ensure my system was stable before tweaking with memory timings.

  • SIP server ("gateway") for joining accounts

    - by Tomas Srna
    Hello, I have a phone supporting 2 accounts, but I need 4 accounts. Is it possible to install some sort of SIP server/gateway/proxy (on a linux server), that would register those 4 accounts and I would be able to connect to it as if it was 1 account? (With dialing rules, etc.) 3 of the accounts have incoming numbers. Thanks. Tomas.

  • How can I troubleshoot Virtualbox port forwarding from Windows guest to OSX host not working?

    - by joe larson
    There are a plethora of questions about virtual box port forwarding problems but none with my specific details. I have a Windows install living in Virtual Box, hosted within OSX. I've got several webservers running on localhost on different ports within the Windows install. I cannot for the life of me get port forwarding to work so I can access those webservers from OSX. My settings look like this (yes I have a NAT adapter): And in my vbox configuration file the relavent portion looks like this: <NAT> <DNS pass-domain="true" use-proxy="false" use-host-resolver="false"/> <Alias logging="false" proxy-only="false" use-same-ports="false"/> <Forwarding name="RLPWeb" proto="1" hostport="7084" guestip="127.0.0.1" guestport="7084"/> <Forwarding name="UtilWeb" proto="1" hostport="4040" guestip="127.0.0.1" guestport="4040"/> <Forwarding name="WCARLP" proto="1" hostport="8084" guestip="127.0.0.1" guestport="8084"/> <Forwarding name="WCAUtil" proto="1" hostport="4848" guestip="127.0.0.1" guestport="4848"/> </NAT> I've turned off the Windows firewall to ensure it is not interfering, and I am not running a firewall on OSX. Anyway, when I attempt to go to for example http://127.0.0.1:4040/ on any of my OSX browsers, it will eventually time out. The log file for this VM shows that it is correctly reading the settings and implying it's doing the right thing here: 00:00:08.286 NAT: set redirect TCP host port 4848 => guest port 4848 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 8084 => guest port 8084 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 4040 => guest port 4040 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 7084 => guest port 7084 @ 127.0.0.1 00:00:08.290 Changing the VM state from 'LOADING' to 'SUSPENDED'. 00:00:08.290 Changing the VM state from 'SUSPENDED' to 'RESUMING'. 00:00:08.290 Changing the VM state from 'RESUMING' to 'RUNNING'. 00:00:08.337 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=000000012017d000 w=1834 h=929 bpp=32 cbLine=0x1CA8, flags=0x1 00:00:09.139 AIOMgr: Host limits number of active IO requests to 16. Expect a performance impact. 00:00:13.454 NAT: DHCP offered IP address 10.0.2.15 I've tried setting the Host IP to 127.0.0.1, and I've tried setting Guest IP blank and also 10.0.2.15. None of these seem to help. What else can I look at to troubleshoot this issue? Details of setup: OSX 10.6.8 Windows 7 Professional 64bit VirtualBox 4.1.2
