I have an assignment to assign a new IP address to my VMware Ubuntu virtual machine and then deploy a WordPress site on it.
I used PuTTY to remotely connect from my Windows 10 host to the VM using ssh.
At first with the default config, I successfully deployed it.
However when I try to change the IP address of the VM by using UI I cannot connect through PuTTY anymore.
Is there anything I did wrong when I changed the IP address like that?
First, you can use openSSH instead of putty on Windows 10 nowoadays.
And you would then connect to it in command line with
ssh user#<serverName / IP address>
But, if you are using an IP address instead of a server name, then yes, changing said IP would change your URL (and your Putty configuration)
I am running Kali Linux on VMware. The host operating system is windows 7, and I'm using NAT for connectivity.
In my metasploit console, when I typed 'exploit' at the msf prompt,(where I am using windows/meterpreter/reverse_tcp as the payload) it showed me the error
Handler failed to bind to My IP:4444
(My IP is my external IP address.)
So in the VMware virtual network editor, I have port forwarded port 4444 of host PC to port 4444 of the virtual PC. Then I allowed inbound packets in the firewall of the host PC, for port 4444 of the host PC.
To ensure that everything is alright, I set up an apache server on the virtual PC, that serves a webpage when accessed via port 4444. The server served flawlessly when I accessed it with an external browser. Satisfied, I shut down the server.
But guess what? Metasploit console has thrown up the same error when I typed 'exploit' again in the msf prompt.
What to do now?
What did it say the reason for failing was.
I'm assuming the full error was failed to bind to port 4444 port is already in use.
You can not run a server on the same port you are trying to bind to.
The correct way to do this is to port forward through your router. Open your router settings and port forward port 4444 to your machines local ip.
I have a Ubuntu Server 16.04 running on a machine in my local network.
The machine has static assigned IP and running apache2. There is no problem in connecting to it from my local network.
I have port-forwarding for ports 22 and 80 setup on my router to the IP address of the machine.
When I check the ports with my public IP address on sites like http://www.canyouseeme.org/ the result is that the ports are open. When I try to connect using my public IP address and using those ports the connections are refused.
I tried disabling firewall in the router and also on the machine, no result.
What else should I try? It seems that the server is getting no incoming connection when I check with netstat.
Just for troubleshooting purposes:
Setup port forwarding on port 22 and try to ssh into your server using the public IP? If it works, it means apache is refusing the connections and not your router or ISP
On your router, setup the server on the DMZ temporarily and check if it works
Add another port forwarding rule on your router to redirect all http requests on port 8000,for example, to port 80 internally, then try to access your server with http://[public_ip]:8000
Have you changed anything on the apache2.conf file? Also, explain how you are testing the connection, internally using the public IP or from the Internet?
I want to test some pages on several machine.
I have tomcat running on one pc lets say PC1 and several pc are connected to PC1. I want other pc to load the one page from PC1. I have tried some alternatives but it is not working
Does anyone know about this??
Thanks
Troubleshooting
From PCX try pinging PC 1: ping PC1
If that succeeds try doing telnet to Tomcat port (default 8080): telnet PC1 8080
That's probably where it will fail, refusing to connect to 8080.
Alternative 1
You have a Firewall blocking the the other PC to access Tomcat port (default 8080).
Alternative 2
Tomcat is binded to localhost only, and you can't access it from another host.
Look for the tomcat/conf/server.xml file and look for some text like:
<Connector
port="8080"
protocol="HTTP/1.1"
address="127.0.0.1"
...
If you find the address attribute, remove it and it should bind to every ip address.
I am a newbie with Apache. I am learning .. after the installation when I tried to start the service I got the following errors.
The Apache service named reported the following error:
Unable to open logs .
The Apache service named reported the following error:
no listening sockets available, shutting down .
The Apache service named reported the following error:
(OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:80 .
The Apache service named reported the following error:
httpd.exe: Could not reliably determine the server's fully qualified domain name, using 192.168.1.6 for ServerName .
The following error usually means that some other program is listening on the HTTP port (80).
(OS 10048)Only one usage of each
socket address (protocol/network
address/port) is normally permitted. :
make_sock: could not bind to address
0.0.0.0:80 .
In my experience, IM (chat) clients like to connect to port 80.
From a command prompt, (cmd.exe) run the command:
netstat -an
See if there is a listener on port 80 (Look for a line that says:
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING
=== ====
the important thing being TCP and 80. If you find something, you'll need to track it down using something like TcpView
If Skype is your problem and it seems it usually is, alter Skype's port usage.
Click on Tools in Skype,
click on Options,
click Advanced,
click Connections.
In Connection is the option to use another port, I use a high numbered port such as 65432, then un-click the alternative use of port 80 and 443.
Close and restart Skype.
modifying C:\Program Files\Apache Software Foundation\Apache2.2\conf\httpd sloved the problem.
If you had installation problems, note that you might experience some errors such “ no services installed ”
if Apache is trying to share port 80 with another web server or application, such as a locally installed
firewall application. To fix this, you can tell Apache to use a different port. Open your httpd.conf file
in the conf subdirectory ( C:\Program Files\Apache Software Foundation\Apache2.2\conf by
default) and locate the following lines:
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the < VirtualHost >
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
#
#Listen 12.34.56.78:80
Listen 80
Change the last line of this block to read:
Listen 8080
skype uses port 80, try logout and shut down the program...
now run apache
if you are using windows os and believe that skype is not the suspect, then you might want to check the task manager and check the "Show processes from all users" and make sure that there is NO entry for httpd.exe. Otherwise, end its process. That solves my problem.
Changing in the config file every occurrence of the path to apache (eg: "C:/Users/xxxx/Desktop/Apache Software Foundation/") to the new location (in case you shifted directory of apache installation by copy paste) solved my problem. Hope it helps you too..
Please note that, not only http port 80, may your ssl port 443 is being used by any other service or software.
I have installed vmware workstation on my PC, so a process which was initiated by Vmware Workstation was using ssl port 443.
In my case, it was vmware-hostd.exe which was utilizing ssl port 443.
Try shutting down vmware-hostd.exe or simply change your ssl-httpd.conf and modify Listen from 443 to 8080 or something else.
While choosing the port number please be sure that you don't enter any port which can be used by any other software on your PC.
just provide the listen address and port in httpd.conf file. that will not show IP related error as
Listen IP_ADDRESS:PORT
If you change port ( not port 80) then port conflict will not occur and server comes up.

Port 80 conflict. There are a number of well-known Windows programs which use
port 80:
IIS
The most likely culprit is Microsoft Internet Information Server. Stop the
service with the command from the command line on Windows 7/Vista:
net stop was /y
If needed start the services again with the command from the command line on
windows /Vista:
net start was /y
