I am trying to setup a remote apache server on centos. I have installed httpd and it is listening to port 80 as it is supposed to. And I am able to connect to the remote system through ssh. but when I try to access the apache server on website using the ip address browser is giving 'Could not connect to error".
My iptable looks like this
I have tried solutions from this question and none of them are working.
Could you have something using NAT in between ? If yes then you have to configure port forwarding.
If you disabled the SELinux using:
setenforce 0
then your server may be behind a firewall, or NAT, and port 80 need to be enabled there.

I am having trouble accessing the weblogic console from a different machine in the same network.
I installed weblogic on a server from a different machine by ssh. The weblogic is up and running, but now I can't access the console on a browser from my machine. Both machines are part of the same network.
I am able to SSH in to the server from my local machine. Ping also works on both machines using each other's IP address.
telnet gives me the following output:
am#Linux-Vostro-3250:~$ telnet 192.x.x.x 7002
Trying 192.x.x.x...
telnet: Unable to connect to remote host: No route to host
This is confusing me, because I am able to access the server using ssh.
I searched everywhere for a possible solution, but I could only find more problems.
In very simple language, how do I resolve this issue or what exactly may the cause be?
There was no firewall cinfigured in the server. I set up a firewall by following the instructions from this site "https://oracle-base.com/articles/linux/linux-firewall"
There are two GUI options but none of them worked for me so better stick to the CLI.
then, using the following command i granted access to my local machine from the server :
# Accept packets from specific host (x.x.x.x).
iptables -A INPUT -s x.x.x.x -j ACCEPT
Now i can access the Weblogic console from my x.x.x.x machine.
I have been given a centos server to lauch eclipse orion code editor. I installed eclipse orion as per the instruction on https://wiki.eclipse.org/Orion/How_Tos/Install_Orion_on_Localhost (steps for linux using jetty server). It works fine on centos browser. The centos os is running on 198.168.1.226. So that I can access the following urls on web browser of centos.
198.168.1.226:8080
localhost:8080
127.0.0.1:8080
0.0.0.0:8080
But when I tried to access the 198.168.1.226:8080 from other local machines on local network, that is not accessible. I searched the StackOverflow Questions like how to make jetty server accessible from LAN? and Unable to access jetty server with local IP address but both are useless for me. How can I fix this situation? Can I fix it editing the code on orion.ini file or need to deal with configuration file or something else?
I have also tried the orion for windows computer but it worked itself for accessing the orion system for any other computer in local network. But I am surprised to face it on centos using the jetty server for setting up eclipse-orion system .
First of all check that have you allowed specific port (8080) from eclispse.
add rule with that port no. in centos iptables as below:-
iptables -A INPUT -p tcp --dport 8080 (adjust according your port no.) -j ACCEPT
Host Machine - Win 7
Guest - Fedora
I have installed nginx web server on guest fedora machine and I can access the webpage inside guest machine using the interface address. How can I access the web page from host machine's browser ?
I am using bridged connection.
Router is assigning 192.168.0.16 to the guest machine's interface. I tried same address in my host machine but it doesn't work.
Based on your description:
First you should check your web application's config. You don't mention which type of your web application running on your Apache server, some are launched with the specific ip argment 127.0.0.1( or localhost), so kind of these web application can only be visited on your localhost computer. You should change the ip argument to 0.0.0.0
Second if the "Fisrt" failed, check the connection of the two server(host and your guest) by using telnet.
On your Win7, you can use the command:
telnet ip port
for example:
telnet 192.168.0.16 80
80 is the default port of Apache Http(s) Server.
if the command don't show the "connection refused" error, your Apache server is goood, so it might be something wrong of your web application.
If that, show me your error msg then we go on further.
I have a VPS with node.js installed, I already uploaded a basic example to test it on the server, so I tried doing this:
I access by SSH, navigate to my project folder and run
node app.js
I get this message
Express server listening on port 8080
I thought i could see my app here
example.com:8080 or server.example:8080... but nothing. Then I tried with the info from os.networkInterfaces(); and os.host(); and still nothing happen
could you help me out? as you can see I am a total noob on node.js. What I'm doing wrong? or what should I do before running my app? Something related to DNS's? i have no idea
How do you ssh to your host? with ip or name? Is it something like:
ssh root#example.com
if so then at least you know your DNS is ok.
Once on the server do a
netstat -a
if you find *:8080 then your server is listening in the default ip. If you see something like 12.23.45.67:8080 then this number is the ip your server is listening.
ifconfig
will give you the servers ip. This should be the same as the ip of example.com. If not then maybe there is some router/firewall in front of your server and you have to configure that to allow port 8080 to reach your server.
if someone ever has the same problem this is how i solved on CentOS:
Open this file
/ Etc / csf / csf.conf
Add the required port
Allow incoming TCP ports
TCP_IN = "20,21,22,25,53,80,110,143,443,465,587,993,995,26"
Allow outgoing TCP ports
TCP_OUT = "20,21,22,25,37,43,53,80,110,113,443,587,873"
Restart
# # Csf-r
I am running ssh on Amazon EC2 (linux) machine on Port 443.
Yet i am unable to ssh it, as i am behind a firewall.
When i do
http:// host:443
Following message is displayed:
SSH-2.0-OpenSSH_5.3
That means ssh is clearly listening on port 443, and the port is even reachable (via browser).
But yet when i do ssh from my desktop command-line (or putty), it just doesn't work.
Is it that firewall is examining packets and blocking it?
Any ideas?
Are you doing ssh -p 443 host? Sorry to state te obvious... but sometimes the obvious is what eludes us.
Worked!
The putty also required proxy entries :)
