SSH Secure Shell, Algorithm negotiation failed

windows

Its happen one of my client is using SSH Secure Shell client to connect to one of their virtual machine.

The error message sound like,

Server responded “Algorithm negotiation failed”.

Key exchange with the remote host failed. This can happen for example if the remote host computer does not support selected algorithm.

Reading this pop-up error message remind me of one of security scanning executed by our security department (obviously) to disable certain cipher and algorithm which they flag as Medium.

This SSH Secure Shell client is a very old program, and does not support modern algorithm for secure connection.

My advice, change to another SSH client instead. Putty is the first suggestion and beside the file transfer capability, it seems that he did not complain.

Problem solved!

Windows 7 64bit update problem

Its happen now and then, Windows will screw up their Windows Update and return with funny error code. This is a very unfortunate event where’s I need my system up and running with latest available update.

Failure to do so will expose machine to vulnerability or maybe features that might useful for daily work.

I bumped one of those error as below.

Spending few minutes on google.com and found out that Windows Support page suggesting to download a tool named “Windows Update Troubleshooter“.
