The Grumpy Troll

Ramblings of a grumpy troll.

SSH and Zeroconf

Memo to self: while ending a ~/.ssh/config file with a block supplying defaults for * is good (as each attribute uses the first match found for that attribute), and adding security checks is good, DNS based checks do not necessarily play well with Zeroconf. In particular, VerifyHostKeyDNS ask is problematic.

To avoid major delays on connecting, it may be helpful to precede that block with:

Host *.local
    VerifyHostKeyDNS no
