So far, we saw how we fix the ssh timeout error. We remove the IP restrictions to fix the error. So, our Support Engineers check the firewall settings and make sure that it does not cause the ssh connection timeout.įor instance, we check the iptables to see if there are any IP restrictions. This can be due to some server-side settings or port blocks in some networks. Many times, firewall settings can cause timeout errors while trying to connect using SSH. Further, we check the SSH configuration file at /etc/ssh/sshd_config and verify the port parameters. Thus, our Support Team will be able to find the port at which SSH runs. To check the SSH port we use the command, netstat -l | grep ssh Then, when the customer tries to connect, the ssh timeout error shows up. Some customers may change the default SSH port 22 to some custom port in their server. We ensure that the users use correct host IP addresses, user details without any typo errors. Therefore, our Support Team begins checking by verifying the SSH connection details. Usually, SSH timeout errors show up when users give the wrong SSH hostname or outdated IP address. Now let’s see the causes for the error and discuss how our Support Team fixes it for our customers. Here xx.xx.xx.xx denotes the host IP that the user is trying to connect.įor users making important server changes, this timeout can be annoying.Ī few reasons for this timeout error include incorrect host IP, firewall setting, port block, etc.Ĭauses and fixes for an SSH timeout error ssh: connect to host xx.xx.xx.xx port 22: Connection timed out

And the SSH user will get the message ‘ssh timeout server not responding’. This event changes the status of an inactive user session to invalid. Usually, the session timeout is an event that indicates an inactive user. For instance, network services like login, remote command execution, etc. SSH is a secure way to login to a remote machine over an insecure network. Today, let’s discuss the ssh timeout error and see how our Support Engineers fix it.

Usually, the SSH connection timeout occurs due to bad server settings, wrong IP hosts, firewall restrictions, etc.Īt Bobcares we often get requests to fix ssh timeout error, as a part of our Server Management Services. The potential issue is that if config changes have been made, but not saved to the startup then you will lose those config changes.SSH timeout server not responding is a frustrating error message for users.Īnd, when it happens while making important server changes, things go for a real toss ! So when you power cycle the switch you will end up running on the startup config. When you power cycle the switch it erases the running config and then it boots using the startup config. To understand the impact of power cycle the switch you need to understand that the switch has a copy of the config which is saved (called the startup config) and a copy of the currently active config (called the running config). It is not quite true that it erases the config of the switch. If console/aux port access does not work then it may be that your only alternative is to power cycle the switch. I am not clear what you are saying about console access and whether you are eventually able to get access via the console. This should allow you to clear the vrty lines which would free up a session that would allow you to SSH again. The best option would be to get access via the console port (or perhaps via the aux port). But having some timeout configured will prevent the problem that you are now experiencing. It can be a very long timeout if you want. I certainly suggest that when you do get access to the switch that you configure a value for the timeout. This is the reason that you get the connection rejected error.

This allows sessions to go on being connected even after the user has stopped using the session and the result is that all of your vty connections are busy. The config that you posted does confirm that the switch has disabled the inactivity timeout (exec-timeout 0 0).
