Server :: Setup Reverse Proxy With Proxy_mod To Port 443 On IIS Server

Aug 30, 2010

We currently have a SUSE Apache2 reverse proxy server setup to reverse proxy (proxy_mod) our GroupWise Web Access server. Our SUSE box is located at www.domain.com. Our GroupWise Web Access server is located internally and is called GWMail. We are in the process of migrating from Novell to Windows, so we will have an exchange server with OWA access running on a Windows Server 2008 IIS7 box. That one will be called EXMail internally. Right now when someone goes to www.domain.com/gw/webacc it goes to the GWMail internal server from the outside world. This was all set up by previous techs who used Linux more.

We would like to set up reverse proxy to be able to reverse proxy to the Exchange Server from the outside world. Unfortunately the snag we are running into is that Exchange needs to run on port 443, and forwarding to port 443 has been a little tricky. I've read elsewhere we need to implement a generic TCP proxy, such as IPtables. what we need to do to get our SUSU Apache2 server to be able to reverse proxy to our Exchange server on port 443. For the save of argument lets call our SUSE server ExtranetServer. Below is our default-configuration.conf file's configuration:

Server :: Reverse Proxy On Squid To Port 8080?

Apr 25, 2011

I have got a reverse proxy that is working just fine, it accepts requests on port 443 and port 80 and ONLY sends traffic upstream to port 80 to the apache server listening on localhost. I use the following config:

https_port 10.14.1.72:443 cert=/etc/squid/self_certs/site.crt key=/etc/squid/self_certs/site.key defaultsite=site vhost
cache_peer 127.0.0.1 parent 443 80 no-query originserver login=PASS
http_port 10.14.1.72:80 vhost

My problem is the following : The site should act differently in some occasions based on whether http or https was requested. So my idea is to setup second http vhost on apache listening to port 8080 and on that vhost I would server the https code. So is it possible to use SQUID to :

Send traffic destined for port 443 to localhost:8080
and
Send traffic destined for port 80 to localhost:80 ?

Ubuntu :: Reverse Proxy Setup - Pass Multiple Domains Thruough One Server To Various Hosts On Local Network

Apr 13, 2011

I'm trying to pass multiple dpmains thru one ubuntu server to various hosts on my local network.

[url] should be sent to the /var/www folder on the local host.

[url] should be forwarded to an IIS box on my local network (owa.nunya.local)

[url] should be sent to another ubunto box on my local network (smtp.biznet.net)

I have tried placing VirtualHost entries in /etc/apache2/sites-available/default and [url]and [url] both work but [url] gets forwarded to the c:inetpub folder on the IIS box.

Server :: Reverse Proxy Solution For SSH?

Jan 25, 2011

I have a server in a corporate data center for a project. I have an SSH access to this machine at port 22.There are some virtual machines running on this server and then at the back of every thing many other Operating systems are working. Now Since I am behind the data centers firewall my supervisor asked me if I can do some thing by which I can give many people on Internet access to these virtual machines directly. I know if I were allowed to get traffic on port other than 22 then I can do a port forwarding. But since I am not allowed this so what can be a solution in this case.

The people who would like to connect might be complete idiots.Who may be happy just by opening putty at their machines or may be even filezilla.I have configured an Apache Reverse Proxy for redirecting the Internet traffic to the virtual machines on these hosts.But I am not clear as for SSH what can I do.So is there some thing equivalent to an Apache Reverse Proxy which can do similar work for SSH in this situation.I do not have firewall in my hands or any port other than 22 open and in fact even if I request they wont allow to open.2 times SSH is not some thing that my supervisor wants.

CentOS 5 Server :: 5.6 - Reverse Proxy With SSL

Aug 24, 2011

I've been struggling with this for a couple of days now. I'm trying to setup a reverse proxy with SSL. The config works when it's not using SSL, but as soon as I setup the virtualhost for 443, I get a ERR_CONNECTION_REFUSED in my browser.

The setup is that it's a CentOS 5.6 running Apache 2.2.3. I was configuring it via this guide: [URL]

This server is acting as a reverse proxy for a Windows server running Apache. Currently, I'm just trying to get the manager page from the Windows server to go through the reverse proxy. Here's the virtual host section of my httpd.conf file on the reverse proxy:

<VirtualHost *:443>
ServerName aspwebview.vtinfo.com
SSLEngine On
SSLCertificateFile /etc/httpd/ssl/star_vtinfo.com.crt

[Code]....

Thoughts? Is there anything I have to do on the Windows server (maybe in the connector section of server.xml)?

Server :: Trying To Configure Apache Reverse Proxy

Oct 4, 2010

I have a question to masters of Apache. In my operating system (CentOS 5) I have installed two Apaches. One is Apache (port 80) from repository where I planning to configure proxy and second one is Apache integrated(port 8090) with KnowledgeTree software. The problem is that when I am trying to configure proxy reverse it simply doesn't work.

This is link to KnowledgeTree software:
- http://127.0.0.1:8090/knowledgeTree

This link I would like to rewrite with proxy like this:
https://myserver.com/knowledgeTree
(HTTPS dont forget)

In my ssl.conf in VirtualHost part I have created something like this:
Code:
<IfModule mod_proxy.c>
<Proxy *>
Order allow,deny
Allow from all
</Proxy>

ProxyRequests off
ProxyPass /knowledgeTree http://127.0.0.1:8090/knowledgeTree
ProxyPassReverse /knowledgeTree http://127.0.0.1:8090/knowledgeTree
<Location /knowledgeTree/>
ProxyPassReverse /
</Location>
</IfModule>

When I am trying to connect I see only: Unable to connect. Firefox can't establish a connection to the server at ifdocu.contaxt.biz:8090.

Server :: Squid As Reverse Proxy - Too Slow ?

Mar 16, 2011

I've been using squid-cache for a long time for authentication/authorization. It has work fine for years, but now it starts working too slow only in one computer (the others, works fine).

It's configured as a reverse proxy.

I see it can be a DNS problem, but the computer is configured with the same dns servers in resolv.conf that the other computers have.

I use squid 2.6.stable14 on RHEL 4.4.

If I restart the service (service squid restart) it works fine, but 15-20 minutes later, the problem repeats.

Server :: Apache Vhost With Reverse Proxy And Redirection

Jan 6, 2010

Here my setup of Apache :
I have two virtual hosts on separate IP and on both I am using port :80 one is main website domain.name and another webmail.domain.name. And to get full link path I am using index.html with redirection derectives. My question how I can setup each Vhost to he is own redirection directive to set two full link like:
when type webmail.domainname -----> redirect to webmail.domainname/horde/imp/file.php
and www.domainname ------> redirect to www.domainname/csr/
Right now working only one of this Vhosts, just problem to separate them when I type www.domainname -----> apache redirect to webmail.domainname.

index.html
<html>
<head>
<title>WebSite</title>
<meta http-equiv="REFRESH" content="1;url=http://www.domainname/csr/"></HEAD>
<BODY>REDIRECTION</BODY>

Networking :: Tuning For High Throughput Reverse-proxy Server?

Jan 18, 2011

I have an enormous quadcore machine with 16gb ram and dual gigabit NICs. It used to be for MySQL but we have upgraded the whole database infrastructure so now this server is left floating. I had the great idea of turning this into a reverse-proxy (using apache mod_proxy) and it really handles a ton of requests. But I have a feeling that we are not getting the most use out of what it can offer.

Our traffic consists of a few thousand very small (less than 10 byte) ajax calls per second, and frequently I find we are running out of kernel allocated network stack to handle all the requests. Often we get the kern.log warning "possible SYN flooding on port 80. Sending cookies." and other things like this. Obviously we are not getting SYN flooded, we just have very high demand.

So far I have found a few kernel tuning guides to tell the kernel to allocate more of the base system memory for networking but every guide I have found has been for the purpose of increasing the performance between WAN links (direct backbones between offices etc) and usually with very large file sizes being the priority. One such example (and great) write up is here:

cyberciti.biz/faq/linux-tcp-tuning/

I was hoping some people could provide further input, such as along the lines of disabling nf_conntrack (to speed up socket set up/tear down time) or anything that will speed up a high throughput proxy like mine. Any links to studies or benchmarks between different configurations or hardware gets extra points!

Server :: Will Squid Work To Reverse Proxy Non-HTTP Traffic?

Aug 2, 2011

I have searched and searched for a reverse proxy solution for non-website traffic. TCP but not http, on ports other than 80, 443, 8080, etc. Basically I just need a TCP forwarder that works with multiple TCP servers, WITHOUT webpage caching features. I do not need or want any webpage caching. Can squid work as a reverse proxy for TCP traffic without http? The other program I came across in searching was HAproxy. Both programs are for http but I am curious if they would work for TCP servers that do not serve webpages.

Server :: Apache Reverse Proxy Slow In Serving HTTP Requests

Mar 18, 2010

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?

Server :: Server Setup Using Ubuntu For SSH Account Hosting For Socks Proxy?

Mar 21, 2010

I have a few friends that have seen me bypass firewalls with a socks proxy (SSH). I explained on how it works and how secure it is for browsing the Internet and checking your email in public places. I had at least 6 asked me if I could set up an account on my server for them and they would pay me! Now what I wanted to know was how I can set this up in a server and website where they can register an account and pay me through PayPal! I don't need help setting up the site! Just on how to set up the server to automate this. What tools are needed (ex. ISPConfig, jailkit.... stuff like that?) I don't mind doing this manually but if I get more people that would like this I don't really want to do every single one.

Ubuntu :: Setup Personal Server To Use As Proxy/Off Site Backup?

I have a simple issue that I think can be solved with several different methods. I basically want to create a personal server solution that allows me to do two things:

1.) I want to be able to remotely backup data to my server.

2.) I want to be able to pass traffic through it and use it as a proxy.

I am off to college next year and I want to leave a computer/server back home to do the two things stated above. I was thinking of using an Asus Eee Box PC like this:url

I want a low power reliable machine that will only be used as a remote solution. I won't be hooking up a monitor to it (that is, after I set it up).

It will be on 24/7 for easy access.

I will be accessing this server from a Windows 7 based machine.

I do not mind at all installing Linux on my server, but I am not an experienced coder so I will need software with a GUI that can help me set this all up.
