How to resolve channel 1: open failed: administratively prohibited: open failed

There are a few reasons why you could get

channel 1: open failed: administratively prohibited: open failed

But essentially it means the port you are trying to tunnel into on the remote machine cannot be opened

To debug the issue

• If you have access to the remote machine check /var/log/secure to get more information on error
• You could try ssh tunnel in verbose mode with -v option
• Try with a different port number on the remote host just to test - some ports are reserved

To resolve the issue - Depending on what the error was from debugging you might have to

• If the error in the secure log was cannot resolve host name - it means you need to restart your network service or interfaces - it could be due to dns server issues
• restart sshd on the remote server - make sure port forwarding is enabled in your ssh config - there are plenty of resources on the net that will explain this
