  • Nginx reverse proxy with separate aliases

    - by gabeDel
    Interesting question I have this python code: import sys, bottle, gevent from bottle import * from gevent import * from gevent.wsgi import WSGIServer @route("/") def index(): yield "/" application=bottle.default_app() WSGIServer(('', port), application, spawn=None).serve_forever() that runs standalone with nignx infront of it as a reverse proxy. Now each of these pieces of code run separately but I run multiple of these per domain per project(directory) but the code thinks for some reason that it is top level and its not so when you go to mydomain.com/something it works but if you go to mydomain.com/something/ you will get an error. No I have tested and figured out that nginx is stripping the "something" from the request/query so that when you go to mydomain.com/something/ the code thinks you are going to mydomain.com// how do I get nginx to stop removing this information? Nginx site code: upstream mydomain { server 127.0.0.1:10100 max_fails=5 fail_timeout=10s; } upstream subdirectory { server 127.0.0.1:10199 max_fails=5 fail_timeout=10s; } server { listen 80; server_name mydomain.com; access_log /var/log/nginx/access.log; location /sub { proxy_pass http://subdirectory/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_max_temp_file_size 0; 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; } location /subdir { proxy_pass http://subdirectory/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_max_temp_file_size 0; 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; } }

  • 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. Things have just ceased to operate correctly, which makes me think it's a freshly added Iptables rule. Here's the Iptables Filter table: Chain INPUT (policy ACCEPT) target prot opt source destination DROP tcp -- ##.##.##.## anywhere tcp dpt:ssh ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt:2199 ACCEPT tcp -- anywhere anywhere tcp dpt:3199 ACCEPT tcp -- ##.###.###.## anywhere tcp dpt:http ACCEPT tcp -- ###.###.##.## anywhere tcp dpt:2199 ACCEPT tcp -- ##.###.###.### anywhere tcp dpt:http ACCEPT tcp -- ##.###.##.## anywhere tcp dpt:http ACCEPT tcp -- ##.###.###.### anywhere tcp dpt:3128 ACCEPT udp -- ##.###.###.### anywhere udp dpt:3128 ACCEPT tcp -- ##.###.###.### anywhere tcp dpt:http ACCEPT tcp -- ##.###.###.### anywhere tcp dpt:https Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere ##.###.###.## DROP all -- anywhere ##.###.###.## ACCEPT all -- anywhere anywhere state NEW,ESTABLISHED Chain OUTPUT (policy ACCEPT) target prot opt source destination ACCEPT udp -- anywhere anywhere udp spt:2199 ACCEPT udp -- anywhere anywhere udp spt:4817 ACCEPT udp -- anywhere anywhere udp spt:4819 ACCEPT udp -- anywhere anywhere udp spt:3199 Help gratefully appreciated.

  • How do you keep track of installed/used software/systems/services in your organisations server infr

    - by edgars
    I'm interested in any software, experience or guidelines listed that help to deal with listing installed services, their primary user (or business person that is responsible for this service), domain names, ip addresses, ports in your servers. Servers are both Windows and Linux, so licenses are also good to track with all of this information. Scale of the infrastructure in question - 20-50 servers. Currently we have no better idea as to use Excel for it.

  • VM connected to network but not to internet in VMware Player 6 on Windows 8.1 host

    - by user1257262
    So I am running Bitnami's MEAN stack in VMware Player 6.0.2 on Windows 8.1 and the VM connects just fine to the network: https://www.dropbox.com/s/xfdzohjuuepz52w/ifconfig.PNG However, I am having a great deal of trouble getting the VM to communicate with the internet. No matter what sort of action I take (even something as simple as apt-get update), the machine just sits there and eventually fails to connect. Here is my VM's Network Adapter configuration: https://www.dropbox.com/s/xfdzohjuuepz52w/ifconfig.PNG On my host Windows 8.1 computer, I actually have the VMware Bridge Protocol enabled but for VMware Network Adapters (VMnet1 and VMnet 8), but they are listed as having No Internet access in my Network and Sharing Center. I am not entirely sure if these adapters are relevant to connecting the VM to the internet, to be honest. This is the first time I have ever had an issue connecting a virtual machine to the internet. This problem is also happening with other VM's I am trying to run. Can someone tell me what I am doing wrong and how I can fix it?

  • Does hosting multiple sites on one server hurt your SEO?

    - by MarathonStudios
    I have a handful of (content unrelated) sites with decent PRs and I'm considering hosting them all on the same server. I've heard that if you do this, internal linking between two seperate domains on that server may be seen as less "valid" by Google in PageRank terms (since you obviously own both of the sites as they share an IP address). Anyone have any experience in this? I'd love to save some hosting cash by consolidating, but not at the expense of losing the ability to link my sites together powerfully.

  • Firewall - Preventing Content Theft & Rogue Crawlers

    - by drodecker
    Our websites are being crawled by content thieves on a regular basis. We obviously want to let through the nice bots and legitimate user activity, but block questionable activity. We have tried IP blocking at our firewall, but this becomes to manage the block lists. Also, we have used IIS-handlers, however that complicates our web applications. Is anyone familiar with network appliances, firewalls or application services (say for IIS) that can reduce or eliminate the content scrapers?

  • What is your approach to draw a representation of your network ?

    - by Kartoch
    Hello, I'm looking to the community to see how people are drawing their networks, i.e. using symbols to represent complex topology. You can have hardware approach, where every hardware unit are represented. You can also have "entity" approach, where each "service" is shown. Both are interesting but it is difficult to have both on the same schema (but this is needed, especially using virtualization environment). Furthermore, it is difficult to have complex informations on such representation. For instance security parameters (encrypted link, need for authentication) or specific details (protocol type, ports, encapsulation). So my question is: where your are drawing a representation of your network, what is your approach ? Are you using methodology and/or specific softwares ? What is your recommendations for information to put (or not) ? How to deal with the complexity when the network becomes large and/or you want to put a lot of information on it ? Examples and links to good references will be appreciated.

  • Is it possible to pick out what applications that should run through a VPN in Ubuntu 9.10

    - by user31257
    Hi, I'm using Ubuntu 9.10 and I'm wondering if it is possible to pick out what applications that should use a VPN. Say for example that I want to route Transmissions connection through a VPN, but I also want to be able to access my computer over SSH via my usual static IP-adress ( running the SSH- deamon over my normal internet connection) . Is there anyway to do this? As I've been searching the web I found that at least it is possible to set whether you want both your internet connection and your "local network" to go through the VPN or if you want just the "local network" to go through it. I'm using the network-manager-pptp with the pptp- protocol.

  • Nginx Rewrite Rule For File Within Folder Not Working

    - by user3620111
    Good evening everyone or possible early morning if you are in my neck of the woods. My problem seems trivial but after several hours of testing, researching and fiddling I can't seem to get this simple nginx rewrite function to work. There are several rewrites we need, some will have multiple parameters but I cant even get this simple 1 parameter current url to alter at all to the desired. Current: website.com/public/viewpost.php?id=post-title Desired: website.com/public/post/post-title Can someone kindly point me to as what I have done wrong, I am baffled / very tired... For testing purposes before we launch we were just using a simple port on the server. Here is that section. # Listen on port 7774 for dev test server { listen 7774; server_name localhost; root /usr/share/nginx/html/paa; index index.php home.php index.html index.htm /public/index.php; location ~* /uploads/.*\.php$ { if ($request_uri ~* (^\/|\.jpg|\.png|\.gif)$ ) { break; } return 444; } location ~ \.php$ { try_files $uri @rewrite =404; fastcgi_index index.php; include fastcgi_params; fastcgi_pass php5-fpm-sock; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_intercept_errors on; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location @rewrite { rewrite ^/viewpost.php$ /post/$arg_id? permanent; } } I have tried countless attempts such as above @rewrite and simpler: location / { rewrite ^/post/(.*)$ /viewpost.php?id=$1 last; } location ~ \.php$ { try_files $uri =404; fastcgi_index index.php; include fastcgi_params; fastcgi_pass php5-fpm-sock; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_intercept_errors on; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } I can not seem to get anything to work at all, I have tried changing the location tried multiple rules... Please tell me what I have done wrong. Pause for facepalm [relocated from stack overflow as per mod suggestion]

  • Configure server on network to analyze traffic

    - by Strajan Sebastian
    I have the following network: http://i.stack.imgur.com/rapkH.jpg I want to send all the traffic from the devices that connect to the 192.168.0.1 router to the 192.168.10.1 router(and eventually to the Internet), by passing through the server and an additional router. Almost 2 days have passed and I can't figure what is wrong. While searching on the Internet for some similar configuration I found some articles that are somehow related to my needs, but the proposed solutions don't seem to work for me. This is a similar article: iptables forwarding between two interface I done the following steps for the configuration process: Set static IP address 192.168.1.90 for the eth0 on the server from the 192.168.1.1 router Set static IP address 192.168.0.90 for the eth1 on the server from the 192.168.0.1 router Forwarded all the traffic from 192.168.0.1 router to the server on eth1 interface witch seems to be working. The router firmware has some option to redirect all the traffic from all the ports to a specified address. Added the following rules on the server(Only the following, there aren't any additional rules): iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT I also tried changing iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT into iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT but still is not working. After adding the following to enable the packet forwarding for the server that is running CentOS: echo 1 /proc/sys/net/ipv4/ip_forward sysctl -w net.ipv4.ip_forward = 1 After a server restart and extra an extra check to see that all the configuration from above are still available I tried to see again if I can ping from a computer connected to 192.168.0.1/24 LAN the router from 192.168.1.1 but it didn't worked. The server has tshark(console wireshark) installed and I found that while sending a ping from a computer connected to 192.168.0.1 router to 192.168.1.1 the 192.168.0.90(eth1) receives the ping but it doesn't forward it to the eth0 interface as the rule tells: iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT and don't now why this is happening. Questions: The iptables seem that don't work as I am expecting. Is there a need to add in the NAT table from iptables rules to redirect the traffic to the proper location, or is something else wrong with what I've done? I want to use tshark to view the traffic on the server because I think that is the best at doing this. Do you know something better that tshark to capture the traffic and maybe analyze it?

Firewall is disabled. How to resolve that problem, please help!?

    We have a SQL Server that has important databases for our clients, if the server goes down we want another server to be ready to be switched over (we would just change the IP).

  • Modem with support for wired 802.1x

    - by menko
    I'm looking at allowing internet access for only a few scattered users on a school network. One method I'm considering is using 802.1x authentication for the modem. Of course there are simpler options like only allowing specific IP or mac addresses, but policy requires something more secure than this. So, are there any modems with 802.1x wired authentication? All my searching on this yields info about wireless.

  • IIS serving locally, but not remotely

    - by cinqoTimo
    There is a router between the modem and the server. In the admin panel, I use single-port forward Internal Port External Port IP 80 80 to 192.168.1.100 (Web Server) Basically, I'm not on site, and there is a local IT person who is supposed to have this ready. I saw the port forward page, and it was configured as described above. So my question is, the only other thing it could be is firewall software, or some other device on the network that their not telling me about, right?

When I add my exchange account to Outlook, it seems to work perfectly (sending/receiving email, syncing everything), but when I open the account settings it has the following set as the Server: [email protected] I would have expects this to be: mail.domain.com since this is the DNS A record pointing to the IP of my server. Where is it getting this server name?

  • Asterisk server firewall script allows 2-way audio from incoming calls, but not on outgoing?

    - by cappie
    I'm running an Asterisk PBX on a virtual machine directly connected to the Internet and I really want to prevent script kiddies, l33t h4x0rz and actual hackers access to my server. The basic way I protect my calling-bill now is by using 32 character passwords, but I would much rather have a way to protect The firewall script I'm currently using is stated below, however, without the established connection firewall rule (mentioned rule #1), I cannot receive incoming audio from the target during outgoing calls: #!/bin/bash # first, clean up! iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X iptables -P INPUT ACCEPT iptables -P FORWARD DROP # we're not a router iptables -P OUTPUT ACCEPT # don't allow invalid connections iptables -A INPUT -m state --state INVALID -j DROP # always allow connections that are already set up (MENTIONED RULE #1) iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT # always accept ICMP iptables -A INPUT -p icmp -j ACCEPT # always accept traffic on these ports #iptables -A INPUT -p tcp --dport 80 -j ACCEPT iptables -A INPUT -p tcp --dport 22 -j ACCEPT # always allow DNS traffic iptables -A INPUT -p udp --sport 53 -j ACCEPT iptables -A OUTPUT -p udp --dport 53 -j ACCEPT # allow return traffic to the PBX iptables -A INPUT -p udp -m udp --dport 50000:65536 -j ACCEPT iptables -A INPUT -p udp -m udp --dport 10000:20000 -j ACCEPT iptables -A INPUT -p udp --destination-port 5060:5061 -j ACCEPT iptables -A INPUT -p tcp --destination-port 5060:5061 -j ACCEPT iptables -A INPUT -m multiport -p udp --dports 10000:20000 iptables -A INPUT -m multiport -p tcp --dports 10000:20000 # IP addresses of the office iptables -A INPUT -s 95.XXX.XXX.XXX/32 -j ACCEPT # accept everything from the trunk IP's iptables -A INPUT -s 195.XXX.XXX.XXX/32 -j ACCEPT iptables -A INPUT -s 195.XXX.XXX.XXX/32 -j ACCEPT # accept everything on localhost iptables -A INPUT -i lo -j ACCEPT # accept all outgoing traffic iptables -A OUTPUT -j ACCEPT # DROP everything else #iptables -A INPUT -j DROP I would like to know what firewall rule I'm missing for this all to work.. There is so little documentation on which ports (incoming and outgoing) asterisk actually needs.. (return ports included). Are there any firewall/iptables specialists here that see major problems with this firewall script? It's so frustrating not being able to find a simple firewall solution that enabled me to have a PBX running somewhere on the Internet which is firewalled in such a way that it can ONLY allows connections from and to the office, the DNS servers and the trunk(s) (and only support SSH (port 22) and ICMP traffic for the outside world). Hopefully, using this question, we can solve this problem once and for all.

  • What protocols will/are ISPs use for IPv6 deployment?

    - by rbeede
    Currently ISPs deal out addresses via DHCP for IPv4 dynamic (single) addresses. What protocol will/are ISPs going to use for IPv6 when they can hand a customer an entire /64 (or /48 if they are nice) block? DHCPv6, RA? For ISPs that support true end-to-end IPv6 will they provide gateway devices (similar to cable modem or true DSL bridges for example) that receive border information for that specific customer? I'm just trying to get an idea of how your common residential service customer will have to configure things in an IPv6 Internet (whenever that comes). Will it be something customers are expected to statically configure on their home wireless router? Today with IPv4 I do it like this: Modem (bridge) passes public IPv4 obtained via DHCPv4 from ISP to second device (wireless router). It in turn has its own DHCPv4 service it provides on the internal lan.

  • Ubuntu Server on live Internet

    - by vaibhav
    I just installed Ubuntu Server 12.04 in an office machine with openSSH, DNS and LAMP Server. I also made the IP static and I can access the server in my office premises easily, but when I try to access my server from my home it is not working. I know I have to make some changes and need to install some firewall (I had just gone through with a couple of posts) but I guess an expert advise will save my time here.
