Networking :: Forward All Http/https Requests ?
May 12, 2010
I 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 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}
[code]....

I'm trying to make my wireless router always give me the same ip address every boot (192.168.1.100). I do not have a static ip address from my isp.
Everything I've tried from online help has made my internet break and I'm not even sure what exactly I should be searching for on google.
Ultimately, I'm trying to get my wireless router to forward ftp requests to my computer which shares the network with an xp machine. I think this is the way to go about it.

I'm trying to use svn over http or https because I'm rear of a corporate proxy. Only allows HTTP connections.
I tried connect-tunnel but no success.
I also modified ./subversion/servers and I added the proxy server but no success.

I need to redirect all http/https/ftp traffic through the remote proxy, but when I changes connection settings in browser or in System->Preferences->Network Proxy it doesn't work well: instead of getting page content browser asks for saving some short (8 bytes) file with the same content for all requested pages. It happens in Chrome/Opera/Firefox. This proxy requires authorization and works on computer with Windos XP. It worked well when I was using Windows 7 and Proxifier, now I have Ubuntu 9.10 with all available updates.

i have a web site and i need to forward all requests to the same page. Basically i would like to show a maintenance page while we are working with our database behind the application and in the meantime i would like to redirect all url in the root directory as following :
http:[url].....
http:[url]....
i tried to perform the action using mod_rewrite in this manner :
Code:
RewriteEngine On
RewriteRule . http://www.mysite.com [L][code].....
The webpage at http:[url]....has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

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?

I want to ENABLE SSL on a PORT 2222 :
Now this works fine. But I also want the HTTP URL to work and redirect it to HTTPS.
When I visit http://IP:2222 I get :
Quote:
Bad Request
Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.
Hint: [url]
How should I make this request of [url] CT to [url]

I'm using a box running CentOS 5.5 powered with Apache2. In this machine I hosted several domains and sub domains, managed by Apache's virtual host.
Due to security issue, one sub domain needs to be able to be accessed either using http or https.
My question is: Is it possible to set a sub domain to be able to be reached using both http and https? If it's possible, how to make it happens?

I'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
Date: Sat, 24 Jul 2010 18:43:58 GMT
etc..

I'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.

I have my Linux laptop running Katatonic Koala at the moment. It is connected via CAT5 to a switch. The switch then connects to my router. All five of my computers are connected to the switch, actually. The only one that won't talk to any sites other than https secure sites is the Linux box. I am not well-versed in the inner workings of Linux and need some help in what I need to do so that regular http sites work. You guys always have the right anwers so I will wait humbly for your replies.

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?

I am trying to configure iptables for only HTTP and HTTPS traffic. I start by blocking all traffic, which works, via:
Code:
iptables -F
iptables -P INPUT DROP
iptables -P FORWARD DROP
iptables -P OUTPUT DROP
I then try to allow HTTP and HTTPS on eth0 with these commands, which does not work:
Code:
iptables -A INPUT -i eth0 -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -o eth0 -p tcp --sport 80 -m state --state ESTABLISHED -j ACCEPT
Code:
iptables -A INPUT -i eth0 -p tcp --dport 443 -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -o eth0 -p tcp --sport 443 -m state --state ESTABLISHED -j ACCEPT After these commands I should be able to access the internet. Does anyone know why this is not working?

I am working on a project to create a video conferencing environment. For this I use a default installation of BigBlueButton on ubuntu 10.04. One of the main problems here is that it's not safe enough to share classified documents trough this software. It's a simple webserver that uses nginx. What I want to do is make this connection secure.
One of the problems is that I don't only have a connection trough port 80 but it uses the following ports:
Port 80 (HTTP), 1935 (RTMP), 9123 (Desktop sharing).
I would like to use a proxy instead of some tunneling or vpn to do this. Would anyone happen to know anything about squid or another equivalent to do this?

When I click on an http link in Thunderbird, nothing at all happens. There's no error message on the console, there's no new browser starting, and there's no new tab opening with the browser already running.
I've tried: sudo update-alternatives --config x-www-browser, choosing firefox.I've also tried: adding a new string value to Thunderbird's warranty-voiding config: network.protocol-handler.app.http, with a value of /usr/bin/firefox. This was recommended in various threads.But no luck.There's an entry for https - firefox on the Attachment tab of the preferences, and https links are indeed opening in Firefox. But not http.KDE 4.4.2 itself has default mail client and browser set to Thunderbird 3.0.4 and Firefox 3.6.3 (both from the repositories, no website downloads).

What is the best way to go about setting up multiple virtual hosts on the same box, one using http and one using https/ssl? I'd like to serve them from the same ip address if possible; I know it's possible in apache 1.3.

Is there a driver or utility to mount an iso image over http or https? There is a httpDisk driver for windows but I can't find anything similar for Linux.
There may be a way of using curl/wget but not sure if this is possible.

How to best manage both http and https pages on the same apache-server without conflicts. For example, if i have both 000-default.conf and 000-default-ssl.conf pointing to mydomain.com, and don't want users who visit mydomain.com without specifically type the https-prefix to be redirected to the https-page - how to handle users using browserplugins such as https-everywhere etc?
Another option would be to create a subdomain ssl.mudomain.com and have users who want to reach the ssl site to have to type ssl. I have tested several things with https everywhere enabled in my own browser, and it seems really hard to make this working the way i want, in one way or another i always end up getting redirected to the ssl-site automatically.
The reason i need this to work is because i run one site that i don't care much about SSL, that is the "official" part of that site, and i also host some things for friends and family on the SSL-part. This would not have been a problem if it wasn't that i use self-signed certificates for my ssl-site and the major user become afraid when a certificate-warning pops up in their browser and therefor leave the site.

I have 2 web server in my office : http and https. You will find attached the httpd.conf and ssl.conf. I can acces the https server from home, but not the http one.
What I did :
configure the router to forward port 80 to my fedora 11 machine
open port 80 with system-config-network
created a virtualhost
The same exact steps have been done for port 443
I can access both server locally but only the https server remotelly.
Here are my iptables :
Code:
you can try to acces my servers using [url]
I made httpd to listen to port 8080, and done all the port forwarding/opening stuf, and it works. so is it a bug ?
Finally found my error seams like turning off UseCanonicalName to off did the trick
I really think it's a bug now. It was definitively working last week, I just added content to the main host of my website, and now i can't acces it from port 80. If someone think it's not a bug or find someting missing/wrong in my conf file.

My router has two bridges, br0 and br1. I'm sharing wifi access, and the guest subnet will be 192.168.2.x.The home subnet will be 192.168.1.x. I want all traffic destined for port 80 from the guest net to forward to a proxy port on a box on the home network. That's the only traffic I want to cross the bridges. How do I set this up with iptables on the router?

I've noticed that when I open firefox I get really strange HTTP and HTTPS connections showing up in firestarter (which as I understand it is just a GUI for IPtables). They connect to various bits of a site listed as 1e100.net (when you use "lookup hostnames") such as wy-in-f18.1e100.net, they stay connected all the time as far as I can see unless I close firefox. I've heard people say they are connected to Google, but I can close all tabs after loging out of google and still see them... it's very odd.
