Battlestar Galactica is now over

Saturday, March 21st, 2009

The ending was possibly the best ending of anything I’ve seen in awhile. I don’t want to spoil it for anyone, so I won’t cover any specific points.

I have hope for the human race where I don’t think I’ve had some for a long while.

Also, Ronald Moore, if you’re out there, thank you. And please, make sure I can buy the entire series in one boxed set on Bluray as soon as possible. I will pre-order it soon as Amazon lets me.

Dealing with SSH’s key spam problem

Sunday, March 15th, 2009

Recently I created a new virtual machine locally, and I tried to ssh into it.

[diablo@infinity ~]$ ssh tachikoma
Received disconnect from tachikoma: 2: Too many authentication
failures for diablo
[diablo@infinity ~]$

I didn’t put a key on tachikoma yet, and ssh didn’t ask me my password. It didn’t make any sense.

So, I ran the same command with -vvv and realized… its sending all my identity keys to tachikoma, and the sshd on that machine is kicking the connection due to all of them failing.

What bizarre behavior.

So I dug around in the man page for ~/.ssh/config, ssh_config and noticed I can just add…

host *
IdentitiesOnly yes

… to force ssh to only use specifically named identities which (what I’ve been doing for years, anyways) are written like this…

host some.remote.host.com
IdentityFile ~/.ssh/id_rsa_some.remote.host.com

… or something similar. With the IdentitiesOnly directive in there, it only sends specifically the identity keys I specify with IdentityFile instead of spamming all the keys I have.

I’m not sure if this is a Debian-only problem (both infinity and tachikoma are Debian machines), but even though its a security feature, its kind of annoying.
