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?
My system is Ubuntu 11Before I typed "telnet localhost" or "telnet localhost 23". I have make this work below:$sudo apt-get install xinetd$vim /etc/xinetd.conf

I am running CentOS 5.1 on VMware on Win 7 On CentOS I added Bridged network adapter and the server is connected to internet without any problems, but when I telnet any server on port 25 I get connection timeout.

Trying 98.137.54.237...
telnet: connect to address 98.137.54.237: Connection timed out

I stopped all servers, iptables and sendmail on the linux server and the firewalls on the win 7 but still getting the same error! I added new network adapter ( host-only ) and tried to telnet the win machine from vmware Linux but I got connection refused

Is strange but my telnet services works (telnet xxx.xxx.xxx.xxx), In addition, i tried with firewall enabled and disabled and the problem still happens. My centOS run on virtualbox.
View 3 Replies View RelatedI'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

Also, during install of the new ubuntu, it was unable to reach the repos for downloading. Odd thing is that I can go online, and that when I type 'ftp.microsoft.com' in my browser, it displays the file-hierarchy.

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
I am facing trouble to scp from server to to my local machine where as the vice-vesra is working fine.
The error is like below.

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.
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
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 getting "ssh:connect to host restart port 22: Connection refused" error when trying to start "ssh" in Ubuntu. I uncommented the port 22 in ssh_config, I dont have iptables setup...Did try to check if the port is listening using the netstat -an | grep "LISTEN" & couldnt find.
View 14 Replies View RelatedI 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).
When I was checking the /var/log/messages, I found these entries:

CUPS is stopped in the system and the system is configured as samba server. What could be the reason for these printing requests from smbd?
I have set up SSH and redirected the ssh server to listen on another port other than 22 for a bit of added security.
Now in hosts.deny I have:
ALL : ALL
In hosts.allow I have:
SSH : ip_address_of_client
I can no longer connect. I get the message: ssh_exchange_identification: Connection closed by remote host.
When I change hosts.allow to read:
ALL : ip_address_of_client
I can successfully connect the server.
However, I only want to allow SSH access in hosts.allow. What is the correct syntax?
I have tried and failed with each one of these:
SSH : ip_address:port_number
SSH2 : ipaddress
sshfwd-portnumber : ip_address_of_client

I am running 11.2 and set ssh to boot at runlevel 3 and 5 through yast and started the service through the terminal. I have turned off the firewall on my wireless router and in the local firewall. When I try to connect from a machine in my office, I get the following
Code:
ssh: connect to host xx.xxx.xx.xxx port 22: Connection refused
When I run telnet from the machine, I get:
Code:
telnet: connect to address xx.xxx.xxx.xx: Connection refused
telnet: Unable to connect to remote host: Connection refused
netstat -tlnp on my machine shows:
Code:

Is the following sendmail scenario possible? If yes, what modification(s) should be made, in order to work?
system1 with host1 - where the sendmail is executed
system2 with host2 - where the destination email address is stored
When trying to sendmail from host1 to an email address stored on host2. but with the format username@host1, the sendmail service returns Connection refused by host1.
