Ubuntu Networking :: "Connection Refused" - Script - Access All PCs In LAN Via Ssh From Server

May 10, 2011

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.

Ubuntu :: Cant Get Access To Telnet Console / 'connection Refused'

Mar 2, 2010

I have an application that uses a telnet console, and I have an autostart script to start it (and check that it is running).The problem is that if the program is not startet by root, or by using sudo, I cant get access to the telnet console, it just says "connection refused".The application works fine, but I cant acces its console, so I have to shut it down, and then restart it with sudo to be able to log in to it.Anyone know how to make the script start the application with enough rights?

Ubuntu Networking :: Setting Up Bluetooth Connection Between Two Computers Throws Connection Refused (111)

Apr 3, 2011

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.

Networking :: Can't Get Into Server Through SSH "Connection Refused"

Jul 24, 2011

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.

Ubuntu Servers :: SSH Server - Connect To Server Via Port 443 I Get A Connection Refused Error?

Jan 7, 2011

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.

CentOS 5 Server :: Openssh 5.8p2 - Transfer Data From Other Server Through Scp It Gives Connection Refused?

Aug 1, 2011

I have configured openssh 5.8p2 with centos 5.6. My sftp is working fine with chroot environment but i am having problem with SCP. I am dealing with muliti Redhat servers. When i try to transfer data from other linux server through scp it gives connection refused. For e.g ssh 5.8 is configured on new server and i want to transfer files from old server which is using openssh 4.3 version.i created same username and password on new server as on old server.My sftp users on new server has no shell access but only sftp access. When i try to scp from old server to new server it gives error connection refused. Is the below configuration only for sftp and can't scp? According to google the configurations i found are for scp and sftp. Do i need to generate ssh keys by giving users on new server shell access, once created then stop shell access again, as i dont want to give shell access permanent for security reasons? but i want to use ssh keys for more security as well.

Port 22
PermitRootLogin no

Fedora :: VNC Server - Get Timeout Or Connection Refused

I have a box running Fedora 14 upstairs and I've been trying to get it to run VNC server, unsuccessfully. I've RTFM, and followed the instructions step-by-step, but it still won't run.

I've read and tried all the troubleshooting; been working on this for about 12 hours now. Is there something major that I could be overlooking?

Ubuntu Networking :: Get A 'Connection Refused' Error

Apr 21, 2010

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.

Ubuntu Networking :: Ssh/sftp Connection Refused?

I'm trying to establish a connection between two laptops using sftp but am getting the following error message:

ftp isn't working either. Both machines are running Ubuntu and connect to the internet through the same wifi router in case that's relevant. What could be the problem?

Ubuntu Networking :: Connection Refused Through Wifi?

Jul 23, 2010

I cant connect with ssh to my workstation using my notebooks wireless lan. with cable I'm able to connect.so the funny thing is, if I first establish a connection from my workstation to my notebook (like ssh it or just ping the notebook) I'm able to create a ssh connection from my laptop to the workstation using wireless lan.scanning my workstation from the wireless lan of my notebook with

Code:
nmap -sT -p 22 ventury
says port 22 is closed

scanning it from the notebook with cable lan,it says port 22 is opened

scanning it from the wireless lan of my notebook an have sent a ping from the workstation before says port 22 is opened.ution.

I got a 64bit version of Kubuntu 10.04, up to date, installed on both, my workstation(ventury) and my notebook (defiant).the question is: Do I always have to ping my notebook first if I want to ssh from it to my workstation or is there some other solution? And why does it work fine with cable, but not with WiFi?

Ubuntu Networking :: Port 22:connection Refused With SSH

Dec 21, 2010

having a port 22:connection refused problem with SSH. None of what I have read has been what I have been experiencing, so I figured I would post here. The worst that could happen is this gets completely ignored, or I am told that there is already a solution, that I missed it, and directed to it. Here is my problem:

Just learned how to ssh into my machine a few days ago. Everything has been running smoothly until I ran into a little problem: all of a sudden I can't connect anymore. I have sshd-server installed and updated. I have sshd turned on

Code:
/sbin/service sshd start
And I even ran:

Code:
/etc/init.d/sshd start
Because I was told that it would start ssh from boot. Nothing has changed from today and yesterday and I haven't been having problems with port 22 being blocked.

I have also tried to ssh into the machine by the machine itself:

Code:
ssh <IP of machine>
with the same error.

Server :: Nagios - Error Message - Connection Refused

May 4, 2010

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.

Ubuntu Networking :: Trying To Open Two Ports - Connection Refused

Apr 12, 2010

I forwarded ports 28900(TCP/UDP) and 5029(UDP) to my linux box for a game. Testing my ports with a website now shows these ports as "connection refused" rather than "timeout" which means the connections are getting to my system but the iptables are blocking them. But I added 28900 as a test and it still won't accept anything on this port. This is my output of iptables -L

root@BPC3:~# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:28900

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:28900

What do I need to do exactly to add exceptions for 28900 TCP/UDP and 5029 UDP?
