Denied SSH Port
- date: October 21, 2012
I've created a server on a computer and I am trying to connect to it through a Linux terminal on another computer running Ubuntu.
To connect I'm using the command:
ssh [email protected]
and it gives me an error message:
connect to host: server_ip_address port 22: no route to host
I'm fairly new to the commands of networking (and Ubuntu forums, I apologise if this post thread is in the wrong area), but how can I solve this problem?
Is there a command I need to run on the server to allow traffic through port 22? Or do I need to connect to a different port?
Netgear router DG834GT and SSH port forward
location: ubuntuforums.com - date: December 7, 2008
Using Ubuntu 8.04
I am almost concluding here that my new netgear router does not work as it is supposed to......(!)
I successfully got into the basics of ssh, vnc and port forwarding recently when I was using my home vigor 2600 router. It was confusing at first but I think I got the hang of it and I could connect to one machine using its internet IP address, with vnc through an ssh tunnel, using keys, from another machine. The same keys are still in place in the two machines so I am not expecting a problem with them (?)
I am now having trouble. With the same two machines, (a laptop trying to connect into a desktop), in a different location, and significantly now using a completely different router which handles port forwarding in a very different way to the way the vigor did.
The router instructions seem clear enough, and I am following them. However, it looks as if the port forwarding is not happening, or anyway, I get a response when using
ssh [IP address of desktop]

SSH port forwarding advanced
location: ubuntuforums.com - date: August 13, 2010
Here is my problem! I recently switched from Windows not suspecting that Linux would put those constraint on my work.
I am a big fan and constant user of putty and especially the port forwarding feature. I often switch and change forwarding options, which is very easy with the right button to the title bar of the connection. So in an established connection I switch with no hassle the option and this works. Also I often use the duplicate this session option.
Now how could one accomplish these routines under Ubuntu?
(change settings of an established session. i even searched for a commands solution)
duplicate an existing session
Does Windows have a better ssh client and options than Ubuntu?!

Change default ssh port number HPUX

Does anyone know how I would change the default port number in HP-UX? It is currently at port 22
[SOLVED] Changing ssh port
location: linuxquestions.com - date: May 8, 2013
I changed the default port by editing sshd_config file and placing the desire port (removed the comment out)
I also updated iptables by removing 22 and putting the desire port.
The centos is 6.4. I had the same issue with 6.3 but forget what I did to fix it. I also turned selinux off.
I am reading about iptables, that the line has to be above the reject command?
If I turned off the firewall, it works.
ssh port forwarding doesn't work on Ubuntu 10.04 LTS
location: ubuntuforums.com - date: June 13, 2012
I have a problem of dynamic port forwarding on Ubuntu 10.04. I have a Ubuntu 10.04 desktop which connects to internet through a proxy. This machine (machine A) is installed with SSH server. From another machine which is also installed Ubuntu 10.04, I tried to use dynamic port forwarding with the command
ssh -D 9999 <user>@machineA
Then, at the SSH client, I configured firefox to use the SOCKs v5 127.0.0.1:9999 as a proxy but I couldn't access to the internet using dynamic port forwarding. I tried successfully with a CentOS server with SSH server enabled.
Most of documents and articles in the Internet say that it's simply to enable X11Forwarding, AllowTcpForwarding and PermitTunnel on SSH server. I'm not sure if this problem is related to firewall rules, Ubuntu 10.04, etc. Do anyone have an idea how to solve this problem?
ssh port forwarding from IPv6 not recognized
location: ubuntuforums.com - date: February 19, 2010
A command like (single quotes used in the command):
ssh -L '[::1]:3128:127.0.0.1:3128' ...
is getting an error message like:
channel_setup_fwd_listener: getaddrinfo(::1): Address family for hostname not supported
This is supposed to be an IP address, not a hostname, for the localhost in IPv6. Anyone know what is wrong with this? Addresses like this work OK in rsync. I know I can use ip6-localhost as a hostname. But right now I'm testing actual IP addresses in IPv6 to see what programs can or cannot handle it.
Samba, ssh, port forwarding, and dynamic IP
location: linuxquestions.com - date: March 19, 2004
I am trying to set up remote access to our office's samba file server and so far I am thinking that port forwarding via ssh is the way to go, but through my research so far I have not been able to answer a few questions.
1. What effect will a dynamic IP address on one end have on the connection system?
2. Both ends are protected via a router, with one of them, my end, already forwarding port 22 to the samba file server. Will the setup require port 22 to be opened on the other end? All connection requests will be coming from within the other network.
3. What setup changes are required, if any, to allow multiple users to remotely map a samba drive at their end or is it only possible to allow one remote user to connect per remote network?
4. Can the setup for remote users be created in the form of a no-brainer connection with a minimal amount of work required each time the want to reconnect. I know they will have to initiate the connection via Putty and I can sto
