Dear Misc@, I am getting some funny behaviour from tailscale (v1.86.2 using Go 1.25.1) on -current. This is on a fresh install on amd64, and I have had this happen both on my (amd64) and in a VM (also amd64):
> # rcctl enable tailscaled && rcctl start tailscaled > tailscaled(ok) > # tailscale up > Post "http://local-tailscaled.sock/localapi/v0/login-interactive": EOF And if I try to run tailscaled on its own in the foreground, then I see the following errors: > magicsock: failed to set UDP read buffer size to 7340032: set udp6 > [::]:36352: setsockopt: no buffer space available magicsock: failed > to set UDP write buffer size to 7340032: set udp6 [::]:36352: > setsockopt: no buffer space available onPortUpdate(port=29858, > network=udp4) > magicsock: failed to set UDP read buffer size to 7340032: set udp4 > 0.0.0.0:29858: setsockopt: no buffer space available magicsock: > failed to set UDP write buffer size to 7340032: set udp4 > 0.0.0.0:29858: > setsockopt: no buffer space available I am not quite sure why this is happening. On my desktop tailscale has been running fine on the following: > $sysctl kern.version > kern.version=OpenBSD 7.7-current (GENERIC.MP) #25: Mon Sep 8 10:44:36 > MDT 2025 > [email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP > $ tailscale version 1.86.2 > long version: 1.86.2 > go version: go1.25.0 Is there something I am missing? I did not see anything mentioned in the install notes, and it used to "just work". Thanks for any comments, rqm
