Server :: Connection Refused By Host ?

Aug 17, 2011

I am experiencing a problem with Nagios running some checks on our Ubuntu 10.04 servers.

we have 16 Nos HDD in each servers. These HDD's are checking by nagios with CPU and users.

For whatever reason, all of the checks will come up with the response: "Connection refused by host".

We have checked the server at the time of occurence and all seems fine. No memory issues, no CPU issues etc.

Then within 5-10 minutes the problem goes away.

General :: Check_NRPE From Ubuntu Server To OpenWRT Router - Connection Refused By Host

May 23, 2011

I am trying to monitorize an OpenWRT (Backfire 10.03, r23115) router from an Ubuntu server, but I am having some problems. I have installed Nrpe (2.12) on the remote host (OpenWRT), I have executed the program as a deamon (/usr/sbin/nrpe -d) but when I start the NRPE deamon, I don't get anything about NRPE executing netstat -at or ps -ef.I would need to install check_nrpe on OpenWRT to find out if NRPE is working, but I can't find any ipk package with it. Now, once in the monitoring host when I try to reach the remote host from the server:

/usr/local/nagios/libexec/check_nrpe -H ip_remote_host

I get: Connection refused by host

Even, trying with localhost:

/usr/local/nagios/libexec/check_nrpe -H localhost

I get the same error: Connection refused by host

I have installed Nagios Plugins and the check_nrpe plugin. I have edited the /etc/nrpe.cfg file:

allowed_hosts=127.0.0.1 ip_server

I don't exactly know if it is remote host's fault, monitoring host's fault or both.

Networking :: Ssh: Connect To Host 192.168.1.11 Port 22: Connection Refused

Dec 11, 2010

I cannot use GRsync from Ubuntu Desktop to PCLinuxOS laptop.The 2 computers can ping each other. I have disabled both firewalls. My laptop IP address is 192.168.1.11This is the error on Ubuntu Grsync:

ssh: connect to host 192.168.1.11 port 22: Connection refused
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(601) [sender=3.0.7]
Rsync process exit status: 12

On PCLinuxOS it wont say Ethernet is connected when trying a static address setup.However it does connect to the internet via auto Ethernet setup and a LAN cable. It then says connected. In order to use SSH and GRsync what programs are required? I have these installed on both machines: grsync openssh-client openssh-server

CentOS 5 :: Ssh: Connect To Host 111.222.33.44 Port 22: Connection Refused

Sep 12, 2010

I have become convinced that rsync for CentOS 5 is broken. I'm trying to set up automatic backups between 2 servers in 2 different countries using rsync under CentOS 5.I can get manual backups to work between the 2 servers by doing two things I shouldn't need to do, but automatic backups fail and I see no solution.Here are the problems I am encountering: According to the instructions I've read everywhere, I am to set up two configuration files:

/etc/rsyncd.conf
/etc/rsyncd.secrets

When I run rsync from root, it apparently just totally ignores these two files. No custom greeting, no log, no password used.
Even when I specify --password-file=/etc/rsyncd.secrets in the command line, it still ignores it. I am prompted and I must enter the password manually. Let me back up a moment. After first installing rsync, when I ran any command to access the root server, I get this error:

ssh: connect to host 111.222.33.44 port 22: Connection refused
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(463) [sender=2.6.8]

I read everywhere that rsync uses port 873, not port 22 which is used for SSH. Why is rsync on CentOS trying to use port 22?I have SSH switched from port 22 to another port (let's call it 5432 here) and block port 22.So, I have added this to the command line:

--rsh='ssh -p5432'

Then I get a connection ...

... but it prompts me for my password. It doesn't matter that I have my username and password, same one, in /etc/rsyncd.secrets on both servers. It still asks.And it rejects my password!The only way I can get it to connect is by creating an SSH user on the remote server for this.Even then, rsync STILL prompts me for a password, even though:

1. the username and password are specified in the /etc/rsyncd.secrets files on both servers

2. I've added the command line parameter --password-file=/etc/rsyncd.secrets Therefore, it is totally impossible to use an any cron job or other automatic synchronization, under CentOS 5.

rsync -av --password-file=/etc/rsyncd.secrets --rsh='ssh -p5432' sourcefiles* rsyncusername@111.222.33.44:httpdocs/rsync
rsync -av --password-file=/etc/rsyncd.secrets --rsh='ssh -p5432' sourcefiles* 111.222.33.44:httpdocs/rsync
rsync -av --verbose --progress --stats --password-file=/etc/rsyncd.secrets --rsh='ssh -p5432' sourcefiles* rsyncusername@111.222.33.44:httpdocs/rsync

Yes, I have made sure that I have the latest rsync. I have run yum update for everything.Yes, I have double checked, triple checked, and quadruple checked my config files.

Fedora Networking :: Ssh: Connect To Host 192.168.1.100 Port 22: Connection Refused

Nov 27, 2010

I have my desktop computer (running F13) configured to accept ssh over port 22 via the firewall configuration tool. If I type ifconfig -a, this computer, which is running on my wireless network, tells me:

Code:

inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0

However, if I go to my laptop computer (also running F13) and try and ssh into the desktop, i.e. ssh icthy@192.168.1.100, I get this response:

Code:

ssh: connect to host 192.168.1.100 port 22: Connection refused.

I guess I am confused to what is blocking the connection? Is there another means on F13 other than the default Firewall? I haven't really messed with the network at all. For what it's worth, I am hoping to set things up so I can just ssh into the computer name, (ssh icthy@desktop) eventually, but want to start with the IP. So, can anyone offer a hint as to what I can look for that is blocking port 22?

This last one is strange as I the IP looks odd.

Ubuntu :: Telnet: Unable To Connect To Remote Host: Connection Refused

Jul 16, 2010

when i try a telnet to a host like that: telnet 10.10.10.10 1234 i got this: telnet: Unable to connect to remote host: Connection refused.

1/ does this mean that the problem is not due to a firewall, but that the host 10.10.10.10 doesn't listen on the port 1234? other way does this mean that my firewall is authorizing traffic on the port 1234?

and when i try a telnet on another port like that: telnet 10.10.10.10 1235 i get: Trying 10.10.10.10 ...

in this case this

2/ does this mean that the firewall is blocking the traffic between my host and the 10.10.10.10 on the port 1235?

Ubuntu Networking :: Ssh: Connect To Host Srv3 Port 22: Connection Refused

May 4, 2011

I have installed ubuntu 11.04 and I'm now trying to connect to existing SUSE servers on the LAN. My home directory has a shared NFS mounted home on the SUSE servers while my home on the ubuntu machine is local. I can log in using ssh to all the SUSE servers except one. I get:

ssh: connect to host srv3 port 22: Connection refused

If I use the IP address of srv3 directly it works. Also, before I changed the default machine name ("ubuntu") I could log into srv3.

nslookup srv3 works OK.
ping srv3 works OK.

Even if I completely delete the .ssh directory in both my ubuntu home and in my shared home on the SUSE servers I still cannot log in using the srv3 name, only direct IP address works. I'm thinking that the login I did to srv3 before I changed the machine name for the ububtu machine must have goofed up something

Programming :: Script - If Telnet Root Hostname Fails Then Try To Ssh In - Error "Unable To Connect To Remote Host: Connection Refused"

May 11, 2010

I'm trying to make an SSH script for my place of employment. This script, I want to go out to the server hostnames we have specified (in another file) and change a users account password. We use Kerberized telnet, so if telnet root hostname fails, I want it to use ssh username hostname and use the old password (specified). If both fail, I want it to ask the user what the port should be and input the port in the ssh command.

But I'm having a issue having it try telnet root hostname and if it fails then, try to ssh in, I have no clue how to have it proceed. Is it an if statement? Here's the telnet failed message: telnet: Unable to connect to remote host: Connection refused

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

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.
