netstat -plnt shows that my port 8080 is listening at 0.0.0.0 but I can't access it with external IP where as localhost:8080 works just fine
If it shows this shouldn't I be able to access this using the servers IP using http://167.99.144.42:8080/ or do I need to forward the port for some reason.
I am using Apache2 on Ubuntu and Nodejs.
167.99.144.42 on port 8080 and 22 is working fine from the public Internet
There is probably a problem with access from your browser such as a local proxy
I'm hosting multiple websites on the same server with multiple tomcat running.
So I want to route
www.example.com to localhost:80/example
and also to route
test.example.com to localhost:8082/example
I heard about a lot of scenarios: mod_jk, mod_proxy using apache http or may be nginx
but I don't know which one is the best and how to do it.
Could you please help me ?
Next step will be to use HTTPS instead of HTTP.
Thanks
The easiest way is to do it with iptables port natting.
(If your application is listening on interface eth0)
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8082
But I prefere using nginx, Apache or HAproxy. there's a lot of tutorials on the net on how to setup a reverse proxy.
I have the following setup:
one public IP
2 different domain names pointing to the same IP above: domain1.com and domain2.com
2 different ssl certificates: one for domain1.com and one for domain2.com
2 physical machines on the same LAN (192.168.1.10 and 192.168.1.20) running Apache2 and debian 8.5
I tested both servers indipendently forwarding the 443 port traffic to either of the machines. They work nicely.
Now, I am forwarding all port 443 requests arriving to the public IP to the first server at 192.168.1.10 and I would like this server to act as a https server for https://domain1.com and redirect the requests for https://domain2.com to address 192.168.1.20
I have tried to configure a reverse proxy in the first machine. It does redirect the requests for domain2 to the machine at 192.168.1.20 BUT it serves the certificate for domain1.
How can I configure reverse proxy as to present the right certificate for each one of my servers?
thank you in advance.

Easiest "solution" (well, workaround) would be to use a single certificate that contains both hostnames. If you cannot do that, then you need to configure Apache SNI, like so: SSL with Virtual Hosts Using SNI
As some suggested I tried to use the Apache2 reverse proxy.
This somehow works but you have to install all the certificates on the machine running Apache2. Thus the trafic on the lan is no longer https which does not satisfy my requirement.
The solution is to use haproxy. This package can be set up as a pass through for https. There are many examples of such applications on the internet. It does exactly what I am asking for: I can host many https servers on a lan behind a nat router with one single public IP. The trafic is sent by haproxy as https to the indicated server on the LAN. If anyone is interested, I will be glad to share my config file solving precisely the problem I set out in my question.
To Robert M:
here is my configuration to be added at the end of the default haproxy.cfg file:
frontend ft_https
mode tcp
option tcplog
bind *:443
tcp-request inspect-delay 5s
tcp-request content accept if { req.ssl_hello_type 1 }
acl domain1_com req.ssl_sni -m end domain1.com # all url ending with domain1.com
acl domain2_com req.ssl_sni -i www.domain2.com # exactly www.domain2.com
use_backend b_domain1_com if domain1_com
use_backend b_domain2_com if domain2_com
default_backend b_default
backend b_default
mode tcp
option tcplog
server srv_default 127.0.0.1:1443
backend b_domain1_com
mode tcp
option tcplog
server srv_domain1 192.168.1.10:1443
backend b_domain2_com
mode tcp
option tcplog
server srv_domain2 192.168.1.20:443
I had to change the https port for apache on the first server to 1443 because both haproxy and apache cannot bind to the same 443 port as they reside on the same machine, but it is transparent to the user.
I recently installed an SSL certificate on my Amazon EC2 Ubuntu 12.04(32bit) server running Apache 2.
When I attempt to access my site via https, it does not load. When I perform an nmap scan, i see that port 443 is not open.
I tried to open port 443 in my ip tables to no avail. iptables -L yeilds
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:https
Here's how I installed ssl
I modified /etc/init.d/apache2.conf to include ssl.conf and modified ssl.conf to include the requisite
paths of my certificate files, ie
SSLCertificateFile /path/file
SSLCertificateKeyFile /path/file
SSLCertificateChainFile /path/file
I configured my security group to allow inbound requests from port 443 (TCP source:0.0.0.0/0)
When I perform the following test with php
if (!extension_loaded('openssl'))
{
echo "not loaded";
}
else
{
echo "loaded" ;
}
I get "loaded".
Any ideas?
In httpd-ssl.conf, do you have
Listen 443
If not, try adding that, and restarting apache.
First check if mod_ssl is enabled. If not, enable it by running a2enmod ssl. Then check if Apache is listening on port 443 for https. Then check if the firewall is not blocking port 443.
If anyone else finds this and is using Amazon Lightsail (like me), you have to use their web UI to explicitly open port 443.
I spent hours pouring over my server config files before I discovered that :/
In httpd.conf the following is disabled by default:
# Secure (SSL/TLS) connections
# Include conf/extra/httpd-ssl.conf
Simply remove the # from the Include and restart Apache.
If you can connect locally (e.g. with telnet localhost 443 as mti suggests), check if the firewall is configured properly.
In my case, ufw was blocking everything, so I had to ufw allow 443 which fixed the underlying problem to the same symptom.
I just ran into a situation where there was a process listening on port 443, the firewall was completely open, SELinux was disabled, and I still couldn't telnet to port 443. Not even from the localhost. I kept getting:
telnet 127.0.0.1 443
telnet: connect to address 127.0.0.1: Connection refused`
It turns out the iptables NAT table had some rules redirect traffic coming in on port 443 to a different port (8443). Nothing was listening on port 8443.
# iptables --table nat --list
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
REDIRECT tcp -- anywhere anywhere tcp dpt:https redir ports 8443
Removing the relevant NAT entries fixed the problem for me.
For me it's the stupid Chrome cache. Ctrl + Shift + Del to clear the cache, restart Chrome, and SSL is correctly working now.
If the SSL keys are not set (or were inexplicably commented out by gremlins), Apache 2.2 SSL will silently fail. There will be no error in the log, and it will not be listening to 443. The http:80 sites will work.
First, Check processes on port "80" and "443" sudo netstat -peanut | grep ':80' and *sudo netstat -peanut | grep ':443'* .If 443 is has no process then this would help:
Editing the Apache configuration file to serve the cert works well.
Use the command sudo certbot --apache
You are good
Sometimes an iptables -F works. I had the port 443 open for inbound in Amazon, but still the site was not opening in my browser.
Logged on to the site, gave an iptables -F and immediately the site was accessible.
Ok so I configured my apache installation on Windows 7 such that it listens on port 8080 by changing the respective entry in httpd.config.
I was too stupid to realize that now I have to access localhost with :8080 at the end.
Question: is there a way to have my box automagically resolve localhost to 127.0.0.1:8080 ? I don't like haviog to type :8080, and NO I CANNOT change the port to 80, I need that one for firewall.
Thanks
no. hostnames have nothing to do with ports. You'll have to specify the port yourself, or set up a proxy on the usual port 80 that will do the 8080 requests on your behalf. ... or bite the bullet and use port 80 directly and move your firewall elsewhere.
