Mosh (mobile shell) is a gift from the Gods(tm). Anyone with spotty internet or wireless connection has suffered the pain of a lost SSH session. Sure, one can fire up screen (or tmux as the kids are using these days), but that's an extra step and you are still using the SSH protocol.

I'm not here to tout the benefits of Mosh, you came here to open it up in your firewall.

Create the following file as /etc/firewalld/services/mosh.xml
firewall-cmd --add-service=mosh --permanent
firewall-cmd --reload

If you tend to have a lot of sessions (not recommended), you can increase the ports, but the default should be fine for most applications.

My thoughts on MessagePack

Hi. My name is Sadayuki "Sada" Furuhashi. I am the author of the MessagePack serialization format as well as its implementation in C/C++/Ruby.

Recently, MessagePack made it to the front page of Hacker News with this blog entry by Olaf, the creator of the Facebook game ZeroPilot. In the comment thread, there were several criticisms for the blog post as well as MessagePack itself, and I thought this was a good opportunity for me to address the questions and share my thoughts.

My high-level response to the comments

To the best of my understanding, roughly speaking, the criticisms fell into the following two categories.

	// A small SSH daemon providing bash sessions
	//
	// Server:
	// cd my/new/dir/
	// #generate server keypair
	// ssh-keygen -t rsa
	// go get -v .
	// go run sshd.go
	//
	// Client:
