I have configured a Nagios server which is working well with all king of clients. But when I added a new windows machine to monitor, it gives a error message "connection refused". I have set everything as prior machines.
Now, I just wanted to know the process by which we can check if server is able to communicate with the client's NSclient daemon. In Linux, we simply issue "./check_nrpe -H hostname" and if ok, it gives the NRPE version which indicates the status ok.

I am merely trying to change the port for my ssh server.However it isn't changing.I edited my ssh_config file to:
Code:
# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for[code]...
When i try to connect to my server via port 443 i get a connection refused error. However when i try to connect via port 22 it connects. Since that didn't work, i tried restarting the entire server.To restate, i changed the config file and restarted ssh then the computer, however the port didn't change.Ohh and yes my router is set to port forwarding on port 443, though it doesn't matter since I'm inside the network.

I need to browse the net more securely and bypass throttling by an infrastructure-dictator by creating a SSH Tunnel directly to my internet service provider and use it as proxy.
I tried both a dynamic and local tunnel, was a able to connect to the server and log-in just fine, but when I tried to surf I get a 'Connection refused' error.
Here's what I tried:
Code:
ssh -D 8022 user@tunnel.host -N
ssh -L 8022:tunnel.host:8080 user@tunnel.host -N
(not at the same time of course)
Then I set 127.0.0.1:8022 as proxy in browser settings. As long as the tunnel is open the browser displays a blank page with no error when I try to open a remote web page, while the terminal gives me a 'Connection refused' error.
I'm using OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007 on Xubuntu Hardy.
In case anybody is wondering this is perfectly legitimate. The tunnel.host I connect to is a server set-up by my ISP specifically for this purpose.
Either of the examples above should work as others who have the same ISP reported that it works. Therefore, I suspect this is an issue with my own security settings which are slightly on the paranoid side but I can't figure out what. Stopping ufw and explicitly opening port 8022 didn't help.

I'm try to setup a database server using mysql, the server starts fine, and I can access it using the built in mysql client via console (adding databases and tables works fine), but the problem is... I always get a connection refused error whenever I access the database outside the built in mysql client (example, if I write a code that connects to mysql). So, I tried execute an nmap command and the only ports open are these ports:
[Code]....
there's no 3306 for mysql... I'm thinking that the firewall is just blocking the port that mysql is using, but my question is, how could the built in client connect to the server if there's no open port for mysql server? Don't clients usually access a servers through ports?

I have FileZilla installed on this machine, and OpenSSH (with an open port 22) on another machine on my home network. When I try and connect, I get: Quote: Status:Connecting to 192.168.2.3... Response:fzSftp started Command: open "alphatwo@192.168.2.3" 22 Error:Connection refused Error:Could not connect to server
Which has left me puzzled as I have an open port. Does the username have to be defined somewhere? E.g. the machine acting as my SFTP server can be logged on to locally as alphatwo so that's what I logged in as (with the correct password). Is this correct? If so, does anyone have any ideas as to how I might rectify it? I want SFTP set up so I can copy PHP files from my laptop to /var/www/html/ on another PC (across the home network).

I'm building a music server using an Alix board with Voyage linux installed on that. The Alix board is attached to my laptop, running Debian, and the laptop acts as the file server via NFS.
I have MPD installed and configured on the Alix board, and have configured NFS on the Alix board to look for the directory where my music files are on the laptop.
I'm directly connecting the Alix board and the Laptop with a crossover cable as I don't want internet access - this is purely for storing and playing my FLAC files via the hi fi. As a result I've setup static IP addresses on both the Alix board and the Laptop, using 10.0.0.1 as the Laptop address and 10.0.0.2 for the Alix board address. Both the Laptop and Alix board have a netmask of 255.0.0.0
The Laptop /etc/network/interfaces output is
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.0.0.0
[Code]....
1. Comment out the "bind to any address = "any" line in the mpd.conf, but that didn't solve it.
2. I'm wondering if I need to setup my routing tables so that it uses a static route, but I don't think that will help as I'm not connecting via a router.
The Laptop is an IBM Thinkpad and not a Mac (I've read about people with Mac's having problems like this).
As far as I know I don't have any firewalls - The Debian install is just disks 1 and 2, and I haven't installed any firewalls (but not sure if Debian comes with one as standard?) The Alix board has the Voyage distribution specifically for Alix and I'm certain that doesn't have anything like a firewall built into it as Voyage is a very stripped down linux kernel.

I downloaded the ubuntu server (command line only) iso and set up a server on a spare computer. The only partition is ubuntu. LAMP server installed, and runs. Its plugged into my home network and the router assigns it a DMZ. I use ptty and that allows me to connect the server from my Windows PC. I installed samba and that works, I set up the server as Z: to my windows PC, and I can now use Filezilla FTP to move gigs of files over from my windows PC to the ubuntu server. I have to log in to activate the connection to Z: but it works.
Problem is getting a database connection from my windows PC (client) to my ubuntu server. Server is running a MySQL server and an Apache Derby server but both give connection:refused every time I try to connect with a java app, or with ij from my client. I tried MySQL Workbench, as that has a GUI, that doesnt connect to MySQL either. Every time I start my server I have to add lots of jar files to the CLASSPATH just to get the Derby server running. The Derby client connection on my client PC is also properly set up with PATH and CLASSPATH etc etc all configured and tested. But the server refuses every attempt to connect even though it tells you the Derby server is up and runnign as listening on port 1527!!!
What I want is a script or app that will "unlock" my server so I can actually do something with it instead of constantly trying new settings and packages in the vain hope it will then actually 'serve'. I am missing something here. There is nothing of value on this server that cannot be 'exposed' to the internet, so I'd be happy to turn off all the security just so the damn thing allowed connections...!

I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.
Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).
Any clues over here? I'm using pand 4.91 and blueman.

I've just completed a fresh install of Ubuntu Server (x64) on a HP Proliant N36L. During the installation I selected to install LAMP, SAMBA and SSH. To continue the installation of software on the server I wanted to connect remotely from windows PC on the same LAN. I am using PuTTY but when I try to connect I get "Error:Connection Refused". I have trawled the forums regarding the setup of putty and openssh and everything appears to be correctly configured.I have checked that the services are running on the server and that the IP address for the server is correct.The guides I have read online suggest that ssh should be correctly configured as part of the install, so why can I not connect from the same LAN?Is the firewall enabled by default during install?

I need to access all PCs in our LAN via ssh from our server in order to do some maintenance. All of them have Ubuntu or Kubuntu Lucid Lynx. Some of the PCs allow this access with no problems, but most of them not. They just answer "Connection refused". I realized that these PCs don't start sshd at startup. If I type "sudo service ssh start" manually in these PCs then sshd starts and all works. But I need it to be started automatically.
I tried some workarounds to solve with no success. I always tried to run a script at startup that could start ssh. If I write a script with this single command inside (service ssh start) and execute it as root, it doesn't work! It doesn't start ssh. But if I execute the same command directly in the command line, it works. I don't understand this behaviour. Also I don't understant why it doesn't happen to ALL the computers. Some of them start ssh at startup with no problems.

Im running a dedicated server for our website(and a few other things) and for some reason, the website suddenly started giving everyone trying to access it a 500 internal server error.
When I went to correct this problem through ssh, it says "connection refused". We don't have an ftp account and webmin isn't working either, is there any other way we can get into the server?
We are running a Apache/2.2.3 (CentOS) Server.

I have about 5 computers on my network that get their internet connection from a Linux NAT server.
192.168.12.02 is a Linux server that has a NAT set up to share the internet connection.
192.168.12.03 is a download server that is almost always downloading
192.168.12.05 - 192.168.12.20 is assigned by DHCP to users.
I want to make it so that the download server runs at full speed but is throttled only when someone from the user IP addresses range tries to use the NAT server.I think I'm looking for some way to set the download server's packets to have a lower priority than the client's packets. Is there a way to set this in the Linux server?

So I setup VNC on my Mac (that runs Snow Leopard) and my PC (that runs Ubuntu) and I gave the IP address to Ubuntu, entered the password and it worked fine. The problem is that it still works fine... I only made this connection to test it because I thought it'd be cool, which it was (for a while). Now I cannot delete this connection whatsoever!
I have tried changing the password on the Mac, limiting the users, and even switching it off completely by unchecking its checkbox. I have also tried limiting the users... BUT UBUNTU STILL MANAGES TO GET INTO MY COMPUTER! This is really annoying because anyone using the PC downstairs can now go into my Mac and mess about with things - I hate this. Somehow, Ubuntu has locked in on my Mac and, despite the changes, can earn access no matter what!

fetchmail: SMTP connect to localhost failed
fetchmail: SMTP transaction error while fetching from stefan%mydomain.com@mail.mydomain.com and delivering to SMTP host localhost
