General :: Transparent Redirect Site To Port 8080?
Nov 4, 2010
Currently my home internet provider does not allow services on ports 1 to 1024 but allow the use of high ports to whatever users want to do and I was wondering what ways are there to mask my webserver @ ip:8080 and yet maintain the servernames ? For example currently if I use myexample.com:8080 it will open just fine but I know there some ways to make it look like if port 8080 never existed, one example of this would be using a proxy server somewhere else to redirect the access but I don't have one available nor money to use for this.
In the above case what would happen is that when user hitted the proxy server it would redirect and query my server so user would never know 2nd server existed at all. Another way would be creating a page somewhere else and put your site as a iframe or frame which would hide it but may be a problem to some browsers etc...
So I belive the question here is what options do I have to mask my server at 8080 to look like a transparent webserver? While I do know this seems a bit technical I belive the place to ask this question would be here instead of serverfault

Finding the process that is using a certain port in linux
I have an Ubuntu Server setup, where I'm trying to set up a daemon that wants to have access to port 8080. When I run the command, the error message says it's being used by another process. But which one, it doesn't say. How can I go about finding which program uses this port?

I want to do a simple port redirect, i.e. whatever comes trough whatever interface on port AAAA will get redirected to port BBBBI thought that iptables -t nat -I PREROUTING --source 0/0 --destination 0/0 -p tcp --dport AAAA -j REDIRECT --to-ports BBBBhowever it doesn't work, e.g. nc -v -w2 -z localhost AAAA gives:
nc: connect to localhost port AAAA (tcp) failed: Connection refused
while
nc -v -w2 -z localhost BBBB

I will be setting up a web server at my house. It will be a simple page for my family to keep in touch and maybe some other stuff. Here is the problem: I believe my ISP blocks port 80. So when setting up the firewall and it list the normal port 80 am I able to edit to say 8080? I have a ddns already setup for my router and I am waiting for an email back from DynDNS.com on setting up a new domain to forward to my already setup hostname. I just need to get everything redirected to another port beside 80.

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 ?

I am a network/system Administrator in an avg. based company, we are using Cent Os as servers. We are developing applications in both php & java, for java we are using apache tomcat as server (port number 8080) & for php we are using apache as server (port 80). Php applications are uploaded in the server and giving the link to our clients like localhost.com/chrome. Now we are planning to give the java based application for testing purpose to clients & can give the application link to client as localhost.com:8080/mozilla. Is it is possible to change the link localhost.com:8080/mozilla to localhost.com/mozilla with out changing the portnumber of apache tomcat server & without interrupting the php applications, that means our clients can access php application as localhost.com/chrome & java application as localhost.com/mozilla in the same server at the same time.

I am having trouble getting my FC10 with tomcat visible to the outside world. first off i am somewhat new to linux. I am running vmware workstation to host my linux web server. i have my VMWare setup to use my second NIC solely. it is bridged and the tcp/ip is disable from the host. i can ping the ip address but cant access tomcat on port 8080 from the outside. i can hit it fine from inside fedora. i have configured my router (wrt54gs with DD-WRT firmware) for port forwarding. so basically i think that the problem is somewhere in between the host and the vmware configuring allowing the port to be forwarded through.

I am setting up tomcat server on my Centos 5.5 machine. I've been advised to run tomcat on 8080 as non root user and redirect traffic to it from port 80.
I searched and found the following iptables commands for this:# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT -to-ports 8080
# iptables -I INPUT -p tcp --dport 8080 -j ACCEPTI have a doubt:
Tomcat is not accessible via port 80 without the second command. But the second command opens 8080 and makes it accessible over the internet (tomcat is accesible via both: www.<website>.com and http://<ip address>:8080). This doesn't seem right. Is there some simple (iptables) way to redirect traffic "internally" from port 80 to 8080 without having to open 8080 to the internet.

My first time installing centos server and adding it to xp home network. I am new to setting up my own network in general. I have a home windows wired ethernet xp network (simple linxs router) with 2 xp boxes and one centos5 box all connected to the same router. I just set up the centos box running tomcat on port 8080. I need to do two very basic things at this point, but am not sure what I need to do:
What do I need to do so I can:
1. Connect in firefox on one of my xp boxes and call the tomcat server running on my centos box?
2. Be able to ftp to centos box from either of my xp boxes?

I have set up an openvpn server on ubuntu via port tcp 443. The server use a public network and almost every ports are blocked (not 443) So when a client connect to the server, if it send traffic needing a blocked port, the connection cannot been etablished of course. So i d like to know if it is possible to redirect all incoming traffic on the server to an other unblocked port (like 443) to bypass firewall.
I dont think openvpn offer this possibility but maybe with linux it is possible..

Here is my network diagram ADSL router----firewall--LAN inside the LAN my squid is running. currently all users are working with out proxy server. I installed the proxy server inside the LAN. now all users can access web browsing ,but no other ports are working , like POP3, smtp, then some other TCP port based applications are not working. My firewall ( juniper) is created and tested the rules to allow the POP3 and smtp and selected poprts which is working , but I redirected through squid proxy server the clients are not able to access. where do I have to create rules?
** in squid proxy( i already did in safe port list stillnot working)

I have "Server A" with real internet ip 1.2.3.4 (eth0) and lan ip 192.168.1.1 (eth1) There's also "Server B" with lan ip 192.168.1.2 (eth0), I'm running an Apache Web server on "Server B", so I want to redirect all traffic from IP 1.2.3.4 port 80 (Server A) to 192.168.1.2 port 80 (Server B), using the following rule:
[Code]....
iptables -t nat -A PREROUTING -p tcp -d 1.2.3.4 --dport 80 -j DNAT --to 192.168.1.2:80 This actually works pretty good, from internet I can browse ttp://1.2.3.4 But the problem is that if I check the Apache logs, all incoming connections seems to come from 192.168.1.1 instead of showing the real source ip addresses (internet ip's) so this is screwing up all my web stats, I've been looking for hours and hours on how to make a transparent redirect, but can't find any info, I know there must be a way because my old WRT54G router which uses iptables could do it.

I'm new to linux, but enjoy using it very much, especially without a GUI, console is fun! I need to set up port forwarding. We have 3 servers, 1x running Ubuntu server 8.04 (used as transparent proxy), 1x server 2003, 1x windows xp.
The linux box has the following ips:
eth0 (internal) 192.168.1.5
eth1 (external) 192.168.0.7
Windows server 2003:
192.168.1.6
Windows XP:
192.168.1.9
Router:
192.168.0.1
The router automatically forwards specific ports to 196.168.0.7 (Linux eth0). From there I want to forward port 8585 to 192.168.1.6 and 3000 to 192.168.1.9. Is there a way that I can do this using iptables?
The commands that I think I'm gonna use look like this:
iptables -A FORWARD -s 192.168.0.0/24 -p tcp --dport 8585 -d 192.168.1.6 -j ACCEPT
iptables -A FORWARD -s 192.168.0.0/24 -p tcp --dport 3000 -d 192.168.1.9 -j ACCEPT
Would this be a correct way of doing it? My biggest problem is that I can't test it without going live, and if I go live and something doesn't work, the entire building will be left without internet, people will hate me. Also, The proxy captures all data on port 80 and forwards it to 3128 so that the proxy can monitor the usage, and a few systems runs fine with it, others however can ping websites, and internet explorer says "website found, waiting for reply" but the webpages cannot be displayed.

This is where it starts: I have 2 networks. The first: 192.168.1.0/24 composed by the router which has access to the internet with the IP 192.168.1 and the server (who is a gateway) with the IP 192.168.1.42 The other network: 192.168.2.0/24 composed by the gateway with the IP 192.168.2.1 and the clients (on the 192.168.2.0/24 subnet). To sum up, the gateway has 2 IPs (192.168.1.4(eth0) and 192.168.2.1(eth1)). On this gateway, I have squid installed (and listening on port 3128). I also made a redirection to redirect some computers who want to access to the web (port 80) to squid (port 3128) with this command: /sbin/iptables -t nat -A PREROUTING -m mac --mac-source CLIENT_MAC -p tcp -m tcp --dport 80 -j REDIRECT --to-port 3128
At this stage, everything works fine. The clients can access the web by the proxy without "knowing". What I wanted to do, is redirect also the port 443 (HTTPS). Actually, when a client wants to access to, for example, [URL]. He cannot. So I would want to be able to redirect people (without passing by any proxy) directly to google. Like a NAT. But the problem is that I can't. The thing would be to, in the gateway, take all the packets with port 443 in destination and handle them to the router 192.168.1.1. Then, when the router sends the packet back, the gateway takes the packet and handles it to the client. I tried putting ip_forward to 1, but the problem is that all IPs and ALL PORTS are forwarded. And I just want port 443 to be forwarded.

* a router/gateway. The external interface have the public IP, an other the DMZ, a third the internal room* a DMZ with the web server* an internal network (internet public room)I redirect the http port 80 to the web server. You should see him there.But I can't see this web site from the internal room. From the public IP /URL I have some sort of non existent message (sorry forgot to copy it). If I call for the private IP, I get the home page (but not the CSS files)the gateway nat's the networks.What is the trick to see the web site from the internal network?

I have multiple jvm instance of tomcat application on a unix server and its running on different port.i would like to redirect the port and uri.How can i achieve this with the help of apache. i heard we can do it using mod_proxy.
[URL]
Currently when i access http://myapp.xx.com/offer i get 404 error.
one way to achieve this is to rename my exploded app name (offers-service-main) to offer. But i dont want to do that.anyway to achieve it.
This what i have done from my side.
1) installed apache 2.2 with mod_proxy
./configure --prefix=/usr/local/apache2.0
--enable-proxy
--enable-proxy-connect
--enable-proxy-http
2) Added the below config in apache
ProxyRequests Off
ProxyPreserveHost On
ProxyPass /offer http://myapp.xx.com:18120/offers-service-main
ProxyPassReverse /offer http://myapp.xx.com:18120/offers-service-main
But the above configuration dosent seems to be work. Let me know if i need to do anything on the tomcat side.

I have a question about anybody who knows how to use firestarter firewall. I'm trying to get access to a Macromedia flash site that needs port 1935 open. While it is not a big issue to open the port, I want to do it just for the server that needs it. I do not want to open it to everybody else. I wonder if anybody has any idea of how to do this. Normally I just go to www.redhotpawn.com which is a chess playing site. I then pressed on the blitz button to go into a game. But it tells me access denied, and then the site has a warning about what it means. The site that mentions that if this is the case then this port has to be open. I don't have a problem of opening the port for the one site as I trust it. But I don't want the port open for every site. I know I can go into the firewall settings and under policy I click on the allow service port for. I put in the port number, but then I don't want to select all. I want to find out what the IP, host or network that I need to allow. Basically I only want to open the port to the one site.
