  • Hosting a web site at home: ISP Blocking port 80?

    - by tombull89
    Hello, I presume this is a better place to put this rather than server fault. I'm interested in setting up a small site to host at home as a "proof of concept" exercise, i.e. to prrove that I know how to do it. I've got a (virtual) server 2003 machine with a site on it, all configured with port forwarding through to 80 on my server. I have a Belkin F5D7634 which I have put my DYNDNS details in but when I try to go to my DYNDNS address it comes up with the page cannot be displayed. My ISP is Carphone Warehouse/AOL and I've been unable to find any information if they block port 80. If they do, can anybody reccomend a home provider that does not block port 80? Regards, Tom.

  • Session persistence between multiple Rails / Unicorn servers with Redis as session_store on AWS

    - by d_ethier
    I've got 2 nginx EC2 instances pointing to 2 Unicorn EC2 instances in a round robin load balanced configuration. The two nginx instances are being the Elastic Load Balancer. Both Unicorn instances have a Redis session_store configured which is in a master/slave configuration with an Elastic IP attached to the master. I've tried configuring the session stickiness on the load balancer, but sessions are lost on each page refresh. I'm using the redis-store gem for the session_store configuration and redis support. Anyone have any ideas as to why this is not working?

  • Mirror DFS configuration data between 2 servers/ sites

    - by Retro69
    I have 1 Windows 2008 R2 server in Site A running Domain Integrated DFS in 2008 mode with a Single Namespace with a large number of DFS Targets all configured to point to a share on our NetApp SAN. Step 1. I want to initially copy this configuration data across to a 2012 server in Site A preserving all the configuration data. Step 2. I need to mirror this configuration to a 2nd server in Site B so we dont have a single point of failure for the DFS namespace. For Example. A user in Site B would "connect" to the DFS server in Site B, but if that site was down, it would attempt to connect to the Server in site A and vice versa. Note im not interesting in replicating actual Data here, just the configuration. Our NetApp SANS have mirroring which take care of that. Is this possible? Many thanks.

  • bind named server - forward some requests to other servers

    - by Pentium100
    Is there a way to make bind answer some queries but forward all other queries (of the same domain) to another server, as in: example.com A 127.0.0.1 www.example.com A 127.0.0.1 everything not on this list (example.com MX, ftp.example.com A etc) - ask 192.168.0.1 (another DNS server) Essentially I want to intercept some (but not all) queries going to (in this example) 192.168.0.1 and answer for it. example.com A- intercept www.example.com - intercept example.com MX - pass trough ftp.example.com - pass trough

  • Web Development - How to access custom host, defined in my hosts file, from another device in the same network

    - by Neara
    Ok, I hope i'll be able to explain the issue im experiencing. I'm working on a project, that has 2 parts: one takes all requests from usual localhost, the other handles requests from myhost.local. While trying to access both addresses from my computer, it works ok. But now i need to test myhost.local on mobile devices, connected to the same network. Usually i would just run server from my computer ip in the network: python manage.py runserver 10.0.0.8:8000 And then from any device, going to 10.0.0.8:8000 would show the project im working on. However, now accessing that ip address routes me straight to localhost. So, my question is how to access myhost.local from another device in same network? I don't want to change router settings, if that can be avoided, cos sometimes i work from places where i can't access router admin. Is there any network settings on my computer, that i can change to fix the routing to myhost.local w.o losing access to localhost as well?

  • Django - Moving database from development to production servers

    - by Garfonzo
    I am working on a Django project with a MySQL backend. I'm curious about the best way to update a production server's database to reflect the changes made on the development server's database? When I develop now, I make some changes to a models.py file, then to a schemamigration using South. Sometimes I do several migrations across several apps within the main project folder before it's ready for the production database. This means that there are several migration files in the app/migrations/ folder created by South. So on the production server, how does one update the database to reflect all the changes made in development, without having any data loss?

  • isolate web servers on intranet with dfl-800

    - by microchasm
    I administer a small network (10 users). I'm getting ready to deploy a internal webapp that will be hosted and accessed locally only. There are about 10 users on the network (192.168.111.0/24), a win2k3 server, apache (RHEL), and Mysql (RHEL), and various miscellaneous peripheries. I'd like to isolate the apache and sql boxes into a seperate area of the lan to keep things easier to maintain/grow. I've been reading about vlans, subnets, etc.. I'm not clear, however, which would be the best solution for our setup. Thanks for any tips and or advice.

  • What is the best IP/Subnet set up strategy for a multi-server webhosting setup?

    - by Roy Andre
    Sorry for the mixed-up title, but let me try to explain better: We run a hosting solution, which until now has supported shared hosting and VPSes. Easy enough. We are now getting larger clients which require a more complex setup. We have more or less settled the server-setup itself, which will consist of: 1-2 Frontend Proxy/Load balancing servers 2+ Application servers 1 Database server 1 optional Memcached server The issue we are dealing with is to agree on a flexible and easy-to-maintain IP setup. So far we've been into VLAN'ing the internal servers in its own subnet, we've though of assigning an official IP to each server, and so on. What will be the best approach here? Any best practices? Using one official IP on the Frontend server, and then just set up an internal subnet for the servers behind that? We could then just NAT in any eventual sources required to access for instance the DB server directly over 3306.

  • nginx proxying different servers for different subdomains

    - by The.Anti.9
    i just set up an nginx server. On the same computer as nginx, I have apache running on port 8000 (this was previously set up.) and I want no subdomain and the www. subdomain to go to the local apache instance. But i want the stuff. subdomain to link to my server where i keep all my miscellaneous files (pictures, documents, etc.), which is also listening on port 80 at the ip 192.168.1.102. I tried configuring it, but when i go to my domain, I just get the "Welcome to nginx!". Here's what I have: user www-data; 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; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; gzip on; include /etc/nginx/conf.d/*.conf; server { listen 80; server_name theanti9.com www.theanti9.com; access_log /var/log/nginx/access.log; location / { proxy_pass http://localhost:8000; } } server { listen 80; server_name stuff.theanti9.com; access_log /var/log/nginx/access.log; location / { proxy_pass http://192.168.1.102:80; } } } I'm not really sure what's wrong. Any suggestions?

  • Differences between Fedora servers

    - by Yarin
    I'm using Amazon EC2 and trying to choose a machine image (AMI) for my project. It seems all their LAMP AMIs are Fedora Core 4, but this seems like quite an old version, considering the current release is apparently Fedora 12, and < 10 releases are no longer supported. My question is how significantly different are the early fedora releases- is it crazy to be on versions 4 or even 8? (I realize this is probably a broad question)

  • Moving email accounts between shared-hosting servers

    - by Michal M
    I've got to move email from one shared-hosting server to another. The reason to move is my current provider doesn't support IMAP, so access to emails is only through POP. I have 5 accounts to move, with 3 of them being 500MB. Is there a way to do it? (other than downloading it all to a client and updating server settings to new server and therefore uploading the files to new server) Any suggestions?

  • reverse proxying with NGINX to two back-end servers

    - by aag
    I am trying to learn how to configure the Nginx proxy. All requests from external (www.external.com) should go to internal server 10.10.10.16:2080, except for www.external.com/nagios requests, which should go to internal 10.10.10.18. My location block looks as follows: location ~* / { proxy_buffers 16 4k; proxy_buffer_size 2k; proxy_buffering off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Accept-Encoding ""; proxy_pass http://10.10.10.16:2080; } # # nagios server location ~* /nagios/ { proxy_buffers 16 4k; proxy_buffer_size 2k; proxy_buffering off; # proxy_set_header Host $host; # proxy_set_header X-Real-IP $remote_addr; # proxy_set_header Accept-Encoding ""; proxy_pass http://10.10.10.18; } The first location seems to work fine. However, any request to www.external.com/nagios sends the browser into the eternal pastures. Of course, 10.10.10.18/nagios was tested and works fine. What am I missing?

  • Virtual Windows Servers and Pagefile location [closed]

    - by Luke Puplett
    Considering that Windows makes heavy use of the pagefile even with huge amounts of RAM available, is it not best to have this pagefile on the fastest disk possible as close to the virtual systems as possible? I'm thinking, RAM disk. Where I work, storage for VMs is out on a NAS/SAN. I'm worried that so much memory access is having to go across the network! As a side, I think its about time MS got rid of paging and told us to buy more DIMMS. UPDATE So this question has been downvoted??! Accessing a local spindle is C40,000 times slower than a DIMM, so going over the network will be even slower for hard faults. I don't know why I got the downvote, I'm certain that this is an issue unless there's some other mechanism in ESX/HyperV that manages this.

  • Exchange - inbound email only works from some servers

    - by Kryptonite
    I am having a problem where inbound mail from outside only works when sent from certain hosts.

  • Improve file transfer speed between Windows PCs and servers

    - by Geotarget
    I've setup a server which I've connected to multiple PCs in my workplace. Sadly, data transfer speeds are at max 3 MB/sec per connection which works out slow for file transfers, especially when transferring large files. I'm using Windows filesharing and the server is a Windows Server 2008 (2 Ghz CPU, 1 GB RAM) and the client PCs mostly running Windows 7. How can I detect bottlenecks in my network and improve file sharing speed within the network?

  • nginx: override global ssl directives for specific servers

    - by alkar
    In my configuration I have placed the ssl_* directives inside the http block and have been using a wildcard certificate certified by a custom CA without any problems. However, I now want to use a new certificate for a new subdomain (a server), that has been certified by a recognized CA. Let's say the TLD is blah.org. I want my custom certificate with CN *.blah.org to be used on all domains except for new.blah.org that will use its own certificate/key pair of files with CN new.blah.org. How would one do that? Adding new ssl_* directives inside the server block doesn't seem to override the global settings.

  • Will spreading your servers load not just consume more recourses

    - by Saif Bechan
    I am running a heavy real-time updating website. The amount of recourses needed per user are quite high, ill give you an example. Setup Every visit The application is php/mysql so on every visit static and dynamic content is loaded. Recourses: apache,php,mysql Every second (no more than a second will just be too long) The website needs to be updated real-time so every second there is an ajax call thats updates the website. Recourses: jQuery,apache,php,mysql Avarage spending for single user (spending one minute and visited 3 pages) Apache: +/- 63 requests / responsess serving static and dynamic content (img,css,js,html) php: +/- 63 requests / responses mysql: +/- 63 requests / responses jquery: +/- 60 requests / responses Optimization I want to optimize this process, but I think that maybe it would be just the same in the end. Before implementing and testing (which will take weeks) I wanted to have some second opinions from you guys. Every visit I want to start off with having nginx in the front and work as a proxy to deliver the static content. Recources: Dynamic: apache,php,mysql Static: nginx This will spread the load on apache a lot. Every Second For the script that loads every second I want to set up Node.js server side javascript with nginx in te front. I want to set it up that jquery makes a request ones a minute, and node.js streams the data to the client every second. Recources: jQuery,nginx,node.js,mysql Avarage spending for single user (spending one minute and visited 3 pages) Nginx: 4 requests / responsess serving mostly static conetent(img,css,js) Apache: 3 requests only the pages php: 3 requests only the pages node.js: 1 request / 60 responses jquery: 1 request / 60 responses mysql: 63 requests / responses Optimization As you can see in the optimisation the load from Apache and PHP are lifted and places on nginx and node.js. These are known for there light footprint and good performance. But I am having my doubts, because there are still 2 programs extra loaded in the memory and they consume cpu. So it it better to have less programs that do the job, or more. Before I am going to spend a lot of time setting this up I would like to know if it will be worth the while.
