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.

Fedora Servers :: SFTP Connection Refused Error: Could Not Connect To Server

Dec 20, 2009

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).

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.

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

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?

I am experiencing a bit of a problem with openssh-server. I installed the server like I normally do. It wouldn't work, so I tried using this. It still didn't work. Later, I have realised that when using service sshd start SSH says it started, but when you check if it's running with service sshd status it says it doesn'triend advised me to use /etc/init.d/sshd and I managed to get it started. However, that doesn't return anything, and when I try to connect it says connection refused even when I try to connect from localhost to localhost

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.

CentOS 5 Server :: Status=deferred - Delivery Temporarily Suspended - Connect To 127.0.0.1[127.0.0.1]: Connection Refused

Apr 6, 2010

For some reason my mail server (Postfix) seems to have stopped delivering mail.

The error in the mail logs is "status=deferred (delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]: Connection refused) against all mails.

I have researched to try and find an answer, most information on this problem seems to point to a malfunction in the Anti Virus and Spam Filtering solution.

I have checked that Amavisd and Clamd are both operating and have restarted Postfix but all to no avail, squirrelmail is not working either.. ie not even producing a login page.

I have not changed anything in the config and am just wondering if anyone has experienced similar and could point me in the right direction of a solution.

Server :: Setup A Database Using Mysql - Always Get A Connection Refused Error

Mar 2, 2010

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?

Ubuntu Servers :: Unable To Connect To Web/Connection Refused

Feb 14, 2011

I have a new Ubuntu server (10.10), named Denholm, recently installed and updated. I came in this morning, attempted to add a package with apt-get, and got a "Connection refused" response. I have another server (also 10.10), named Moss, on the same network that can connect successfully.

Here's what I've found/tried so far:

This doesn't look like and apt problem anyway, but the sources.list files on Denholm and Moss are identical.

I can ping [URL] (and other sites) successfully from Denholm.

I have tried 'wget www.google.com'. From Moss the wget is successful, but from Denholm I get "Connection refused."

I have a web server on Moss and Denholm can successfully access it.

To the best of my knowledge, Denholm is not configured to use a proxy server (no http_proxy variable set).

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.
