Fix UDP Buffer Sizes for cloudflared tunnel

cypr0 opened this issue · 1 comments

With the current config I get the following error when starting cloudflared tunnel:

failed to sufficiently increase receive buffer size (was: 208 kiB, wanted: 2048 kiB, got: 416 kiB). See https://github.com/quic-go/quic-go/wiki/UDP-Buffer-Sizes for details.

To fix this for Debian, modify cluster-prepare.yaml.j2 as follows:

sysctl_config:
fs.inotify.max_queued_events: 65536
fs.inotify.max_user_watches: 524288
fs.inotify.max_user_instances: 8192
net.core.rmem_max: 2500000
net.core.wmem_max: 2500000

Fixed in 28ae26d thanks for reporting!
