• Archlinux/atheros WLAN configuration troubles

  - by GrinReaper

  I'm trying to config archlinux to use my wireless network adapter. It's quite troublesome. From what I've gathered, it's an atheros network adapter, using the ath5k driver/module... I can't get it to work; any ideas? Here's some of the output from my tinkering: # lspci | grep -i net 00:0a.0 Ethernet controller: nVidia corporation MCP67 Ethernet (reva2) 03:00.0 Ethernet controller: atheros communications inc.

Sorry, first time using a linux distro... EDIT: So I just tried this: I actually just did this twice. (I can't tell which setting is on/off for my wireless adapter. The lights are blue all the time now.) #rfkill list 0: hp-wifi: wireless lan softblocked: no hardblocked :yes 1: hp-bluetooth: bluetooth softblocked: no hardblocked :yes 3: phy1: wireless lan softblocked: no hardblocked :yes #rfkill list 0: hp-wifi: wireless lan softblocked: no hardblocked :no 1: hp-bluetooth: bluetooth softblocked: no hardblocked no 3: phy1: wireless lan softblocked: no hardblocked :yes 7: hci0: bluetooh 0: hp-wifi: wireless lan softblocked: no hardblocked :no I've dug around some other articles and it seems like ath5k is supposed to be preferable to madwifi, so should i be using madwifi? I'm 99% sure I disabled the hardblock (by turning it ON) but, as shown above, phy1 wireless lan is STILL hardblocked. What gives? Maybe I've made some more fundamental error in a basic config file? EDIT: I've fixed the hardblock. I've tried pinging www.google.com, but to no avail. I get: ping: unknown host www.google.com In the arch wiki: Edit /etc/hosts and add the same HOSTNAME you entered in /etc/rc.conf: 127.0.0.1 archlinux.domain.org localhost.localdomain localhost archlinux To my understanding, hostname is just a user-specified and based on preference(?) My /etc/rc.conf: HOSTNAME="gestalt" My /etc/hosts: 127.0.0.1 localhost.localdomain localhost gestalt but should it be the following? 120.0.0.1 localhost.domain.org localhost.localdomain localhost gestalt

• Not being able to `make` in terminal on Mac OS X 10.7

  - by AlanTuring

  Hi so i am trying to install the commands wget and with-readline for use with Mac OS X's terminal. The configuration seems to work fine for both even though i am required to specify for the first one, host= i686-apple. When i get to the make part of the installation, the output is as follows. For wget: for with-readline so does anyone have any idea what's going on? Pastie links: wget: http://pastie.org/4925079 with-readline: http://pastie.org/4925083 Thanks in advance.

• Is it a good idea to use virtualization for apache/php and Mysql servers?

  - by Cédric Girard

  Hi, we (our company) provide SAAS (software as a service) applications, and we think about virtualization to host our apache/php servers, and our mysql master/slave servers. Is it a good idea? Mysql servers need fast I/O and memory, and both need high network bandwith. How to make the right choice? Thanks Best regards Cédric

• How secure is a bluetooth keyboard against password sniffing?

  - by jhs

  In a situation where an admin will enter sensitive information into a keyboard (the root password), what is the risk that a bluetooth keyboard (ship by default with Mac systems these days) would put those passwords at risk? Another way of asking would be: what security and encryption protocols are used, if any, to establish a bluetooth connection between a keyboard and host system?

• What "pieces" are needed in order to set up a cluster of physical servers?

  - by Chris Dutrow

  Background: Currently, we use Rackspace cloud servers. We have no intention to stop using them, but would like to look into setting up a cluster of physical servers (probably desktop computers in the $400 range with 8gb memory each) to offset some of our load and work as a secondary, more powerful, less reliable system. To put things in perspective, we can buy comparable desktop computers for the same price as we pay in one month to rent them on Rackspace Cloud. I understand that this is generally a dumb idea. However, in this particular instance, the server cluster is needed for its computation power. It is not mission-critical, it does not host a consumer-facing website, and if it goes down for a day or two, its not really a problem. Currently, we have access to business class verizon fios. If I understand correctly, we can get at least 25 dedicated IP addresses with this service, this should be enough. Requirements: Each server runs Linux Centos 6.3 Some of the servers run Python and execute processes from a task queue (Redis or RabbitMQ) Some of the servers are capable of serving static files and Python driven REST APIs Some of the servers host a Cassandra database cluster One or more of the servers are a Redis database servers One or more of the servers are PostgreSQL servers Questions: What kind of router or switch is needed? We would like the computers to be able to communicate effectively with each other via internal IP addresses. This is especially important for communicating with servers hosting Redis that need to be able to respond to requests very quickly. Are there special switches or routers that need to be used to connect the servers together? Are Desktop computers ok for this? We have found that we are mostly RAM-bottle necked, I understand that some servers have highly superior CPUs, but I'm not sure we need CPU power as much as we need RAM, which is cheap in Desktop computers. Will we have problems with the WIFI cards in the desktops or any other unexpected hardware limitation? What tools should be used to "image" the servers. For example, when we get an installation right for a Redis server or Cassandra node, are there tools that come with Linux Centos 6.3 to image the server to a USB drive or something like that? Or do we need to use some other software for this? What other things are we missing that we should be concerned about? Thanks so much!

• Add DNS record for subdomain on different web hotel

  - by Martin Wiboe

  Hi, I am quite inexperienced with DNS, so this might be simple. Our main domain foo.com is hosted at provider A. Now, we would like to host bar.foo.com at some other provider B - they have the domain set up with them, so I figure that I can do this by somehow adding the nameserver at provider B to the DNS configuration at provider A. The current DNS config is as follows: http://imgur.com/kG099.png How can I add the new subdomain to this configuration? Regards, Martin Wiboe

• Windows 2008 RRAS and PPPoE

  - by Massimo

  I'm trying to use Windows Server 2008's Routing and Remote Access Server to share an ADSL connection which uses PPPoE, but I'm having no luck. I can setup the connection as a broadband Internet connection in Windows, and it works. I can share it using Internet Connection sharing, and it works (but it's not what I need). I have installed and enabled the Routing and Remote Access Service and configured it for NAT with a demand-dial interface; I create the aforementioned interface using PPPoE with the exact same parameters used on the Windows connection; I connected it, and it seems to work: I can also see it gets its public IP address and DNS assigned correctly. But it just doesn't work. The server has no Internet connectivity at all, and PINGing anything on the Internet results in a cryptic "general error". Any help?

• Autoloading Development or Production configs (best practices)

  - by Xeoncross

  When programming sites you usually have one set of config files for the development environment and another set for the production server (or one file with both settings). I am assuming all projects should be handled by version control like git or svn. Manual file transfers (like FTP) is wrong on so many levels. How you enable/disable the correct settings (so that your system knows which ones to use) is a problem for me. Each system I work on just kind of jimmy-rigs a solution. Below are the 3 methods I know of and I am hoping that someone can submit a more elegant solutions. 1) File Based The system loads a folder structure based on the URL requested. /site.com /site.fakeTLD /lib index.php For example, if the url is http://site.com then the system loads the production config files located in the site.com folder. However, if I'm working on the site locally I visit http://site.fakeTLD to work on the local copy of the site. To setup this I edit my hosts file and add site.fakeTLD to point to my own computer (127.0.0.1/localhost) and then create a vhost in apache. So now I can work on the codebase locally and then push to the server without any trouble. The problem is that this is susceptible to a "host" injection attack. So someone loading site.com could set the host to site.fakeTLD and then the system would load my development config files instead of production. 2) Config Based The config files contain on section for development - and one for production. The problem is that each time you go to push your changes to the repo you have to edit the file to specify which set of config options should be used. $use = 'production'; //'development'; This leaves the repo open to human error should one of the developers forget to enable the right setting. 3) File System Check Based All the development machines have an extra empty file called "development.txt" or something. Each time the system loads it checks for this file - if found then it knows it is in development mode - if missing then it knows it is in production mode. Since the file is NEVER ADDED to the repo then it will never be pushed (and checked out) on the production machine. However, this just doesn't feel right and causes a slight slow down since all filesystem checks are slow.

• Apache/Jboss Issue - is this connection timeout?

  - by user115391

  We have an application. The architecture is as below 1 load balancer (apache), which redirects to 2 app servers (jboss). The site is working fine and I am able to access it fine. But sometimes, randomly the homepage takes a while (like 30-40 secs) to load. I tried checking the logs but could not figure out why. I used the httptraffic analyzer, fiddler to see the traffic, but it just says the request/response took 30 secs or so. I checked the apache access logs, mod_jk.log. My configurations are below mod-jk.conf LoadModule jk_module modules/mod_jk.so JkWorkersFile conf/workers.properties JkLogFile logs/mod_jk.log #JkLogLevel info #JkLogLevel debug JkLogLevel error # Select the log format JkLogStampFormat "[%a %b %d %H:%M:%S %Y]" JkOptions +ForwardKeySize +ForwardURICompatUnparsed -ForwardDirectories JkRequestLogFormat "%w %V %T %P %{tid}P %D" JkMount /__application__/* loadbalancer JkUnMount /__application__/images/* loadbalancer <VirtualHost *:8080 > JkMountFile conf/uriworkermap.properties </VirtualHost> JkShmFile run/jk.shm <Location /jkstatus> JkMount status Order deny,allow Deny from all Allow from 127.0.0.1 </Location> ----------------------------- uriworkermap.properties Simple worker configuration file # Mount the Servlet context to the ajp13 worker /=loadbalancer /*=loadbalancer ----------------------------- workers.properties worker.list=loadbalancer,status worker.template.port=8009 worker.template.type=ajp13 worker.template.lbfactor=1 worker.template.prepost_timeout=10000 worker.template.connect_timeout=10000 worker.template.ping_mode=A worker.worker1.reference=worker.template worker.worker1.host=hostname1 worker.worker2.reference=worker.template worker.worker2.host=hostname2 worker.loadbalancer.type=lb worker.loadbalancer.balance_workers=worker1,worker2 worker.status.type=status ----------------------------- my jboss server.xml - $JBOSS_HOME/server/default/deploy/jbossweb.sar/server.xml --------------------------------- The logs from access log is below The issue where it took time - look at the seconds column [23/Mar/2012:12:10:38 -0400] "GET / HTTP/1.1" 200 138 x.x.x.x - - [23/Mar/2012:12:10:49 -0400] "GET /index.jsp HTTP/1.1" 302 - x.x.x.x - - [23/Mar/2012:12:11:10 -0400] "GET /home.jsp HTTP/1.1" 200 936 x.x.x.x - - [23/Mar/2012:12:11:31 -0400] "POST /login/ HTTP/1.1" 200 8895 x.x.x.x - - [23/Mar/2012:12:11:52 -0400] "GET /login/includes/login-style.css HTTP/1.1" 304 - The one after the issue x.x.x.x - - [23/Mar/2012:12:12:18 -0400] "GET / HTTP/1.1" 200 138 x.x.x.x - - [23/Mar/2012:12:12:18 -0400] "GET /index.jsp HTTP/1.1" 302 - x.x.x.x - - [23/Mar/2012:12:12:18 -0400] "GET /home.jsp HTTP/1.1" 200 936 x.x.x.x - - [23/Mar/2012:12:12:18 -0400] "POST /login/ HTTP/1.1" 200 8895 x.x.x.x - - [23/Mar/2012:12:12:18 -0400] "GET /login/includes/login-style.css HTTP/1.1" 304 - Would it be a cache or timeout issue?

• debian mysql server always down

  - by lokheart

  I am hosting a mysql server in a debian 6.0.4 server hosted in linode, the new data is frequently written into the mysql server using R, about 30-40 "write" per minute, about 7 hours a day, 5 days a week. Recently I found that the mysql server seem to down frequently, always give me error that mysql server cannot be connected through socket. I wonder if this is caused by my high demand to my mysql server, and if this can be solved. I am definitely a newbie in manage server. Please let me know if I need to provide additional information for this question in order to get it solved. Thanks.

• Cloud hosting for windows domain controller, possible?

  - by Preet Sangha

  We currently host our own domain controller (small company) locally on dedicated h/w. However to mitigate disaster recovery we're considering the use of virtualisation and cloud hosting. One thought is Virtual primary domain controller hosted in the cloud + a local (secondary) virtualised server running in the office as a cache? Is this possible or should I consider something else? We're happy to pay for the decent hosting and DR but this is really out of my experience.

• 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?

For this we have defined StartCalendarInterval and this all works very well. Now it happens that I would like to start one of these jobs out of schedule, but this does not start the job (but also does not give an error/warning): sudo launchctl start org.job-label The manpage of launchtl states that start is intended to test on-demand jobs, no word of scheduled jobs. Is there a way to kickstart scheduled jobs?

Many are outdated, or just flat out wrong. server { listen *:80; server_name <%= @fqdn %>; #root /nowhere; #rewrite ^ https://$server_name$request_uri? permanent; #rewrite ^ https://$server_name$request_uri permanent; #return 301 https://$server_name$request_uri; #return 301 http://$server_name$request_uri; #return 301 http://192.168.33.10$request_uri; return 301 http://$host$request_uri; } server { listen *:443 ssl default_server; server_name <%= @fqdn %>; server_tokens off; root <%= @git_home %>/gitlab/public; ssl on; ssl_certificate <%= @gitlab_ssl_cert %>; ssl_certificate_key <%= @gitlab_ssl_key %>; ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers AES:HIGH:!ADH:!MDF; ssl_prefer_server_ciphers on; location / { # serve static files from defined root folder;. # @gitlab is a named location for the upstream fallback, see below try_files $uri $uri/index.html $uri.html @gitlab; } # if a file, which is not found in the root folder is requested, # then the proxy pass the request to the upsteam (gitlab puma) location @gitlab { proxy_read_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694 proxy_connect_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694 proxy_redirect off; ect.... I've restarted after every configuration change, and yet I still only get the 'Welcome to nginx' page when visiting http://192.168.33.10. whereas https://192.168.33.10 works perfectly. Why will nginx still not redirect http requests to https? tailf /var/log/nginx/access.log 192.168.33.1 - - [22/Oct/2013:03:41:39 +0000] "GET / HTTP/1.1" 304 0 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:24.0) Gecko/20100101 Firefox/24.0" 192.168.33.1 - - [22/Oct/2013:03:44:43 +0000] "GET / HTTP/1.1" 200 133 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:24.0) Gecko/20100101 Firefox/24.0" tailf /var/log/nginx/gitlab_error.lob 2013/10/22 02:29:14 [crit] 27226#0: *1 connect() to unix:/home/git/gitlab/tmp/sockets/gitlab.socket failed (2: No such file or directory) while connecting to upstream, client: 192.168.33.1, server: gitlab.localdomain, request: "GET / HTTP/1.1", upstream: "http://unix:/home/git/gitlab/tmp/sockets/gitlab.socket:/", host: "192.168.33.10" Resources http://wiki.nginx.org/Pitfalls How to make nginx redirect How to force or redirect to SSL in nginx? nginx ssl redirect Nginx & Https Redirection https://www.tinywp.in/301-redirect-wordpress/ How to force or redirect to SSL in nginx?

• Certain clients (IP range) can not ping server

  - by Logman

  I just virtualized a Windows 2003 Server SP2 x32. The server contained our help desk server (Spiceworks) and our anti virus management server (ESET RAC). The host computer actually contained the virtualized server originally; I created the vhd and then I wiped this system clean and installed Windows 2008 R2 x64 Datacenter and added the virtualized 2003 onto the Hyper-V 2008 R2 Server. I got the server running fine except for... certain ip ranges. Local clients can get updates from the AV server from my 192.168.180.xxx & 192.168.181.xxx BUT NOT from any 192.168.182.xxx, 192.168.183.xxx, 192.168.184.xxx etc... I can not ping the server from any clients except for the 180. & 181. ranges. Now I created 2 other virtualized servers (win2008 & a win7 pro) and they exist on the same virtual host as the 2003 server. And at first I could not ping those until I went to the "\Network and Sharing Center\Advanced sharing settings" and Turned On File and Print Sharing. Then I could ping and access those virtualized guests. Win2003 server isn't quite the same. But I am sure I have it on. But now when I ping from a client on one of those ranges that would not work I get this: As you can see the ping leaves our network. We have 2 ad/dns servers (one 180. & the other in the 181. range). Is it DNS? Both AD/DNS servers are Windows 2003. And we plan on upgrading both to 2008 R2 within a month or two but I need to fix this issue pronto (esp the AV end). btw, I did rename that 2003 Server (Spiceworks/AV) hostname. And I tried a CNAME. But I do not think that is the problem. EDIT: OR because this server existed on this hardware/computer before becoming virtualized?

• Is there another way to run Apache2 securely for end users without using CGI mode?

  - by Volomike

  Is there another way to run Apache2 securely for multiple end users (like hosting hundreds of blogs) without using CGI mode as required by suPHP? It just seems so inefficient to use CGI mode for PHP when if we could set up permissions properly, we could host PHP through mod_php perhaps? I mean, I do want to restrict these users to their home directories for their sites, but don't want any security issues.

• Reverse DNS Lookup from the Command Line

  - by user41322

  I'd like to get a list of all domains pointed to a certain IP address. Is there a way to get this information from the command line? Nothing like "host", "nslookup" or "dig -x". Those return the hostname of the IP address which, while helpful, is only part of what I want returned.

• Making hosts accessible between LAN subnets

  - by nixnotwin

  I have two inerfaces on my router with tomato firmwre: br0 and vlan4. br0 is on 192.168.0.0/16 subnet and vlan4 on 10.0.1.0/24 subnet. As I don't want the different network services on br0 available on vlan4, I have added this firewall rule: iptables -I INPUT -i vlan4 -j ACCEPT; iptables -I FORWARD -i vlan4 -o vlan2 -m state --state NEW -j ACCEPT; iptables -I FORWARD -i br0 -o vlan4 -j DROP; vlan2 is my WAN (internet acess). The issue that I want to solve is that I want to make one host from 192.168.0.0/16 network (br0), which has ip 192.168.0.50, available on vlan4 (10.0.1.0/24). Only that host should be available on vlan4 (and all other hosts on br0 should be inaccessible). What firewall rules can be used to do it?

• iso is already present on server

  - by andygriff

  Hi, I'm using SCVMM R2 with Windows 2008 R2 hosts. I've noticed that if I have an iso mounted on a vm from the scvmm library and then a snapshot is restored then you always get an error .iso is already present on server when trying add it again. I know you can log onto the Host and delete the iso from the Virtual Machine foler but that will be a nigthmare in a 200 VM strong implimentation. is there another way?
