ssh – remove offending key.

Whenever a system/server is re-installed or the host key changed for any reason, you would have seen the “host key verification failed”. And as usual you would have to go to known_hosts file and delete the offending key. I will show you 2 simple ways to do this here.

The output that you get in such scenario is:

Offending ECDSA key in ~/.ssh/known_hosts:4

First, you can use sed to directly delete the offending key with a command like this :

Simple rss to email service for your feeds on Linux with your/ISP server.

I like couple of blogs and feeds but the problem is that I keep forgetting to run the rss reader and would rather like to have the rss article’s emailed to me at regular intervals so that I can read them when I want to without having to make sure that I am at my desktop at home computer or remembering to start the rss client. That sounds simple and do-able so lets try to do that.
