I assume that *:* means that any foreign host can connect from any port, but then what does [::]:* mean? and localhost:ipp... what port is ipp? Shouldn't ports be numeric?
Right now I have a machine set up running Fedora. I have configured inittab to accept Console Logins, but I am having problems getting my netbook running PuTTY to connect. How would I go about finding the Host Name and Port to connect to?
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 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:
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 have a Windows machine on which NX Client has been installed. I wanted to test if I could access my Ubuntu box. The Ubuntu Box has NX Server, Node and Client installed. When I try to log in from the Windows machine using NX Client with my Ubuntu username and password I get an error connection refused.
The following service is running: OpenBSD Secure Shell server sshd How can I resolve the issue?
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'm trying to connect with my server via telnet, but when i sent the command (telnet xxx.xxx.xxx.xxx Port) doesn't works and shows then follow error: Unable to connect to remote host: Connection refused, It happens with any port. 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.
I'm trying to ssh from my laptop to my desktop (both fedora 14) over a local network. I can ping my desktop and get responses, but if I ssh to it, I receive
ssh: connect to host 192.168.100.xxx port 22: No route to host
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.
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 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.
I'm having problems with ssh and don't know what else to do. I keep getting "ssh: connect to host stop port 22: Connection refused" when i try to stop or start ssh:

I've been trying to ssh out of my home network to school computers and I keep getting:
ssh: connect to host sage.math.washington.edu port 22: Connection timed out
I've tried this on my machine (running Ubuntu 10.04) and on a windows 7 machine (using putty). I have been successful ssh'ing to this machine using either of the laptops from every other network I've tried, so I'm pretty sure it's something about my home network.
had some problems with setting up Linux on my virtual machine as I cannot connect with putty (connection gets refused) to it but now I guess I figured my problem out, just not the way how to solve it .If I do netstat -nap | grep :22 I get the following output:[[ see attachment ]]
Shouldn`t there be some kind of LAN IP instead of 0.0.0.0?Does anyone have a possible solution for that? Checked iptables and such, they are not causing it.
I'm trying to open port 8080 on my application server. I've included it in my iptables; however I still cannot access through ssh nor putty and it doesn't show up when I netstat either.Here is my iptables-config:
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -i eth0 -s xxx.xx.x.0/24 -j ACCEPT
OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to server ["address"] port 22. debug1: connect to address "address" port 22: Connection timed out ssh: connect to host "server" port 22: Connection timed out
I suppose this is because I am connecting from a public institute where there is a firewall that is blocking an outbound connection on port 22.Is there anyway I can bypass the firewall using the internet ?
Lets say i have two machines on public ips. If i get incoming traffic on machine #1 on port 55242 i would just like to forward it to machine #2 on port 35000.I would just like to use machine #1 same way as a dns server works. It just redirects the traffic and tells the client where to go.
I see three separate intermittent symptoms on the 10.0.0.0 network. 1) Both machines will cut off in the middle of the data transfer (rsync) if it takes too long. 2) Both machines will claim that the RSA key host has changed on the other...this will happen every few minutes. 3) Both machines will, at times, disallow login from the other...ssh prompts for password but will not accept the password.
Performing any operation between the same machines via the 192.168.1.0 subnet has no issue (as of yet).From what I can see, the routing tables are set correctly. Machines were exact clones of each other. Machine 2 is a recently rebuilt machine with a fresh suse11 distro install. Symptoms on Machine 2 appeared immediately. I had this exact setup but reversed ip addresses before Machine 2 burned out without issue. All networks but the 12.0.0.1 are internal and there hasn't been any indication of attack.At times, running ssh-keygen -R <ipaddress> will fix issues 1-3, other times only 1-2.
I performed a F13 to F14 upgrade today and it went very well. The only problem I'm having is that I can longer Telnet to the machine.The client side returns a "connection closed by foreign host" message or "connection to host lost", depending on the client.The /var/log/messages file contains "FATAL: bad tty" following every telnet attempt.I receive the same error even when trying to telnet to localhost on the local machine.
Trying 192.168.100.9... telnet: Unable to connect to remote host: Connection refused
[Code].....
This last one is strange as I the IP looks odd.
What I am doing wrong, and how do I fix it. After much surfing many mosts say that telnet is not used anymore but I want to use it to test my smtp server.
is it possible using a perl script to test for a socket listening on a UDP port on a remote host ?I work in an environment where netcat is not allowed and from time to time I need to see if a UDP port is open on a remote host.
have fedora 10 and am having problems with ssh. For some reason I can't connect via a remote host to my ssh. Local network connections do work just fine. I have been looking for a log of what is going on but have not had luck seeing anything.Things I have tried:
-Modify hosts.allow to allow ssh to all -generated rsa1 key identity tryed specifying that with the -i option on the guest computer
I have VMWare on a notebook, guest Windows running on Linux host. The network in that virtual machine is configured as NAT. I want to share/transfer files from Linux (host) to Windows (guest). So I leave sshd always running on the notebook, I go into Windows and run an SSH/SFTP program. My Wifi router has address 192.168.1.1, my desktop has address 192.168.1.2 and my notebook has address 192.168.1.3. On the notebook, that SSH/SFTP program connects to 192.168.1.3 (i.e. the notebook itself) and everything works fine. But it's a notebook, and when I leave home with it, 192.168.1.3 is no longer accessible. How can I let the guest OS connect to the host OS when I'm away from my Wifi network?
