My computer shares an internet connection using an ADSL router.There are other three machines.I have set up a Apache server for learning purpose and I want it to be inaccessible from anywhere else including the PCs in the network.When I enter my ip-address assigned in the network (192.168.1.1xx) from other computer,I get my ppages and I dont want that.
How can I block HTTP requests from other computers?
i have recently had a house mate move in and he is using my wireless network, even though i asked him not to give out the network key to his friends either he has or they have hacked my network and are using it when they come over, is there a program i can use to monitor the number of computers that are connected to my network and block them, or is there a way i can just wee what is going on. They seem to just connect and i don't want to have to change the password particularly because that involves changing it on multiple devices.

View 9 Replies View RelatedHow do Http requests and responses go from a client to the server? IS a TCP Connect Tunnel always formed or is there some different mode ?
View 4 Replies View RelatedI have a server (Fedora 12) setup at a client's datacenter and the network is setup to allow me ssh access into the server, but prevents me from opening any connections from the server. However, I need to make http and https request from the server. What I'd like to do is forward all http/https traffic through another machine outside the network.
I've been looking at the documentation for ssh and the various options there and have gotten so far as to enable initiating an ssh connection from the client network back to my machine, but am not sure where to take it from there.
Here are some of the commands I've used so far:
Code:
I'm attempting to bind port 80 to be forwarded through the local machine. I assume I use "ssh -R" to create a dynamic tunnel to forward requests but I must be missing something.
By the way, root login via ssh is disabled.
For some of the files that I share using Apache, I want to make sure that they are served ONLY via https.
How can I configure this for Apache?
We have a cisco ASA firewall at work,which redirects all http traffic to our webserver. We have to install a new website ,but it can't be installed to the same server. Setting up a squid reverse proxy can redirect the incoming http requests to the appropriate webserver? If yes, could I get some directions on howto?
View 5 Replies View RelatedI'm learning about the HTTP protocol and I'd like to know if there's a tool I can use to input a HTTP request I have created myself that will output the raw response. I've had a look at cURL and wget but they don't seem to have an obvious option to do this. For example:
$ http_response < my_http_request.txt
HTTP/1.0 200 OK

View 1 Replies View RelatedI've had a VPS running Ubuntu 9.10 x64 server, hosting 3 websites of mine for a few months now. This problem has been happening for a while. Every once in a while, probably every 2 or 3 days, I'll wake up in the morning, and apache won't be responding, no web pages will load. /etc/init.d/apache2 status, reports that apache is functioning properly. Every time I simply have to restart the daemon and things run fine for another few days.
I thought maybe it was a memory issue, so I lowered the MaxClients in the prefork module from 50 to 30 a few days ago, but the same thing is still happening. My VPS has 512MB of ram, burstable to 1GB, and according to Virtuozzo, there was only one night of high traffic where I even came close to that soft limit. I've checked my syslog, and there's absolutely nothing in there about apache. I've checked apache's error.log as well, and there's nothing in there that would indicate a problem either.
For one project I use a web hosting service. I wanted the entire site to be https, so I bought a service from them in which they automatically install a trusted cert so people can access the site through https protocol. Since http is still available, though, I need to do automatic rewrites or something to change http into https requests. (I don't have access to their Apache server configuration files or anything like that.)I found on the net this code to add to my .htaccess file:
Code:
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

A Linux (CentOS5.3) server is setup with apache reverse proxy. The reverse proxy server is opened to outside and an internal server is mapped to ProxyPass configuration. SSL certificate is also installed on the Apache reverse proxy server. The problem is, it is extremely slow in serving http requests through reverse proxy. There is no problem with server resources or bandwidth. When the internal server is directly accessed through Internet, there is no delay. The backend server and the reverse proxy server are also on the same switch (same subnet). When I searched the Net, there were recommendations to enable cache in Apache. I did so as follows in httpd.conf.
<IfModule mod_disk_cache.c>
CacheEnable disk /
CacheRoot "/var/cache/mod_proxy"
CacheDirLevels 5
CacheDirLength 3
</IfModule>
But still there is no progress. Do I want to enable cache in ssl.conf too? Or is there any other workaround to speed up Apache reverse proxy. Is there a way to check that caching is happening?
Background:I have a small PC104 running opensuse 11.1. I'm writing a small client/server application for debugging purposes using mono and WCF. All the client does is make a request for information every 100ms.Problem:After about 20 requests the server quits responding to the client. Even if the client is running on the same machine. I've run the exact code on another laptop running opensuse as well as a laptop running windows and everything works great. Hopefully that closes the option that it is a code, mono, or opensuse flaw.Is there a kernel option or a network option that anyone knows about that might cause this sort of behavior?

I run a small home server (Debian 4), which acts as my gateway to the internet (ie, firewall) and runs a web server, dhcp, dns, and acts as a file server to the rest of the machines on my home network. Now I know it's never a smart idea to have all those services running on the same machine that is acting as a firewall, but I don't fancy running multiple servers just for home use, as it's mainly allowing me to learn system administration.
I noticed a few days ago that my internet had become unbearably slow, to the point where I could sometimes not load web pages. I spent a while searching through log files on my gateway, to try and find out what was eating up all of my bandwidth. When I came to apache's access.log file, I was confronted with this:
Code:

Multiple requests to my server, for totally random websites. I didn't even know it was possible to make those types of queries to a webserver. The only thing that is on the web server is a browser based torrent client. I have only shown a small snippet of the log file, but there are around 90k lines to different web addresses, from many different IPs. What I want to know, is what is happening? :S Why is someone querying MY web server, for web sites totally unrelated to it? And most of all, how can I stop it. My initial was to try and use iptables to block multiple requests from the same ip within a certain time frame, which I think would work as the server shouldn't really get many queries from external networks.
I have suspicious requests in my haproxy logs from multiple sources to the same target. I could deny them in /etc/hosts.deny, but there are too many to keep track of. Is there a way to deny all requests to a specific target either in haproxy or through iptables?
Here's an example of the request: Apr 12 15:11:37 127.0.0.1 haproxy[28672]: 41.105.42.150:27072 [12/Apr/2011:15:11:37.315] web_servers frontend_farm/######## 3/0/1/1/169 404 1073 - - --NI 3/3/2/1/0 0/0 "GET /images/comment_icon.gif HTTP/1.1"
I've commented out my amazon instance id for security purposes. The request is for comment_icon.gif which does not exist. All requests go to that. The source IPs are from different countries as well. Blocking a certain country won't work either. Basically, if there was a way to send all requests for comment_icon.gif to /dev/null or something it would work.
