Would you mind sharing the known host line in /Users/daniel/.ssh/known_hosts:4
? It's likely that you have an invalid host line that wasn't added by upterm
and upterm
complained about it when trying to write a new host line for the uptermd server
Same issue here, but the reported line is the one created by upterm:
@cert-authority uptermd.upterm.dev,[2a09:8280:1::3:4b89] ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAICiecex8Dq718eSe1CCLgLvDmI7AagvCtax7brPFWkh4
IPv6 addresses are added with brackets to avoid ambiguities, and OpenSSH mandates an explicit port with the bracketed syntax.
The issue is that golang.org/x/crypto/ssh/knownhosts.Normalize
omits the port when it's the default one, even when adding brackets,
which is not valid according to sshd(8)
/ "SSH_KNOWN_HOSTS FILE FORMAT".
Upstream issue: https://github.com/golang/go/issues/53463
After running upterm an invalid entry is added to the
known_hosts
file. Attempting to run upterm later results in the following error:OS: Darwin 21.6.0 Darwin Kernel Version 21.6.0: Sat Jun 18 17:07:22 PDT 2022; root:xnu-8020.140.41~1/RELEASE_ARM64_T6000 arm64 Upterm: Upterm version v0.9.0 Removing the entry enables you to run upterm again. Manually adding port 22 to the address resolves the issue.
